query: Teaching hospitals do not provide better care than non-teaching hospitals.

positive: Patient Outcomes with Teaching Versus Nonteaching Healthcare: A Systematic Review Background  Extensive debate exists in the healthcare community over whether outcomes of medical care at teaching hospitals and other healthcare units are better or worse than those at the respective nonteaching ones. Thus, our goal was to systematically evaluate the evidence pertaining to this question. Methods and Findings  We reviewed all studies that compared teaching versus nonteaching healthcare structures for mortality or any other patient outcome, regardless of health condition. Studies were retrieved from PubMed, contact with experts, and literature cross-referencing. Data were extracted on setting, patients, data sources, author affiliations, definition of compared groups, types of diagnoses considered, adjusting covariates, and estimates of effect for mortality and for each other outcome. Overall, 132 eligible studies were identified, including 93 on mortality and 61 on other eligible outcomes (22 addressed both). Synthesis of the available adjusted estimates on mortality yielded a summary relative risk of 0.96 (95% confidence interval [CI], 0.93–1.00) for teaching versus nonteaching healthcare structures and 1.04 (95% CI, 0.99–1.10) for minor teaching versus nonteaching ones. There was considerable heterogeneity between studies (I2 = 72% for the main analysis). Results were similar in studies using clinical and those using administrative databases. No differences were seen in the 14 studies fully adjusting for volume/experience, severity, and comorbidity (relative risk 1.01). Smaller studies did not differ in their results from larger studies. Differences were seen for some diagnoses (e.g., significantly better survival for breast cancer and cerebrovascular accidents in teaching hospitals and significantly better survival from cholecystectomy in nonteaching hospitals), but these were small in magnitude. Other outcomes were diverse, but typically teaching healthcare structures did not do better than nonteaching ones. Conclusions  The available data are limited by their nonrandomized design, but overall they do not suggest that a healthcare facility's teaching status on its own markedly improves or worsens patient outcomes. Differences for specific diseases cannot be excluded, but are likely to be small.

negative: Implementation of a Clinical Pharmacy Education Program in a Teaching Hospital: Resident Oriented Documentation and Intervention The aim of this study was to provide a clinical pharmacy education program at Masih Daneshvari hospital, a University affiliated hospital, located in Tehran, Iran. For this purpose, the most common pharmacist involved interventions and aspects of potential fields for pharmacy students and residents education was firstly identified. Clinical pharmacy interventions and drug information forms were filled during the study period, from January 2006 till January 2007. Based on the results of this study, a total number of 772 interventions were conducted during the study year. Drug information had the highest rate of 22.30% among all interventions, followed by dose adjustment, and therapeutic reduction or addition. The mean number of medications per patient was 8.62 ± 7.54. In conclusion, it could be said that although in our country the challenge for the pharmacy as a profession is in its initial stages compared to the developed countries, the result of this study revealed a high demand for this service among health care providers.

negative: A case-mix classification system for explaining healthcare costs using administrative data in Italy. BACKGROUND The Italian National Health Service (NHS) provides universal coverage to all citizens, granting primary and hospital care with a copayment system for outpatient and drug services. Financing of Local Health Trusts (LHTs) is based on a capitation system adjusted only for age, gender and area of residence. We applied a risk-adjustment system (Johns Hopkins Adjusted Clinical Groups System, ACG® System) in order to explain health care costs using routinely collected administrative data in the Veneto Region (North-eastern Italy). METHODS All residents in the Veneto Region were included in the study. The ACG system was applied to classify the regional population based on the following information sources for the year 2015: Hospital Discharges, Emergency Room visits, Chronic disease registry for copayment exemptions, ambulatory visits, medications, the Home care database, and drug prescriptions. Simple linear regressions were used to contrast an age-gender model to models incorporating more comprehensive risk measures aimed at predicting health care costs. RESULTS A simple age-gender model explained only 8% of the variance of 2015 total costs. Adding diagnoses-related variables provided a 23% increase, while pharmacy based variables provided an additional 17% increase in explained variance. The adjusted R-squared of the comprehensive model was 6 times that of the simple age-gender model. CONCLUSIONS ACG System provides substantial improvement in predicting health care costs when compared to simple age-gender adjustments. Aging itself is not the main determinant of the increase of health care costs, which is better explained by the accumulation of chronic conditions and the resulting multimorbidity.

negative: The impact of organisational change on outcome in an intensive care unit in the United Kingdom Objectives: To study the change in outcome for patients admitted to an intensive care unit following the establishment of a team of resident medical staff and a change from an "open" to a "closed" organisational format. Design: Database review of prospectively collected data. Setting: Intensive care unit of a postgraduate teaching hospital. Subjects: 1134 admissions to the intensive care unit over a 3-year period, of whom 476 (42%) followed elective surgery. Main outcome measure: Hospital mortality corrected for illness severity by using the APACHE II scoring system. Results: Crude hospital mortality fell from 28% before the changes to 20% afterwards (P=0.01). With correction for case-mix factors, the probability of death after the changes was reduced by almost half (OR 0.51; CI 0.32, 0.82, P=0.005). Conclusion: A "closed" format of organisation of the delivery of care may result in improved outcomes for patients admitted to intensive care units.

negative: Cost effectiveness of ward based non-invasive ventilation for acute exacerbations of chronic obstructive pulmonary disease: economic analysis of randomised controlled trial. OBJECTIVE To evaluate the cost effectiveness of standard treatment with and without the addition of ward based non-invasive ventilation in patients admitted to hospital with an acute exacerbation of chronic obstructive pulmonary disease. DESIGN Incremental cost effectiveness analysis of a randomised controlled trial. SETTING Medical wards in 14 hospitals in the United Kingdom. PARTICIPANTS The trial comprised 236 patients admitted to hospital with an acute exacerbation of chronic obstructive pulmonary disease and mild to moderate acidosis (pH 7.25-7.35) secondary to respiratory failure. The economic analysis compared the costs of treatment that these patients received after randomisation. MAIN OUTCOME MEASURE Incremental cost per in-hospital death. RESULTS 24/118 died in the group receiving standard treatment and 12/118 in the group receiving non-invasive ventilation (P=0.05). Allocation to the group receiving non-invasive ventilation was associated with a reduction in costs of 49362 pounds sterling (78741 dollars; 73109 euros), mainly through reduced use of intensive care units. The incremental cost effectiveness ratio was -645 pounds sterling per death avoided (95% confidence interval -2310 pounds sterling to 386 pounds sterling), indicating a dominant (more effective and less costly) strategy. Modelling of these data indicates that a typical UK hospital providing a non-invasive ventilation service will avoid six deaths and three to nine admissions to intensive care units per year, with an associated cost reduction of 12000-53000 pounds sterling per year. CONCLUSIONS Non-invasive ventilation is a highly cost effective treatment that both reduced total costs and improved mortality in hospital.

negative: Long-term survival, quality of life, and quality-adjusted life-years among critically ill elderly patients. OBJECTIVES To assess mortality, quality of life (QOL), and quality-adjusted life-years (QALYs) for critically ill elderly patients. DESIGN Cross-sectional survey. SETTING A ten-bed medical-surgical intensive care unit (ICU) in a tertiary care university hospital. PATIENTS The study group included 882 elderly patients (> or =65 yrs of age) and 1,827 controls (<65 yrs of age) treated during the period of 1995 to 2000. INTERVENTION None. MEASUREMENTS AND MAIN RESULTS Mortality was assessed during the ICU and hospital stays, and 12, 24, and 36 months after ICU discharge. The cumulative 3-yr mortality rate among the elderly (57%) was higher (p < .05) than that among the controls (40%). The majority (66%) of the elderly nonsurvivors died within 1 month after intensive care discharge. All elderly patients with day-1 Sequential Organ Failure (SOFA) scores >15 died during the ICU stay. QOL was assessed with EQ-5D and RAND-36 measures from 10 months to 7 yrs after discharge. The majority (88%) of the elderly survivors assessed their present health state as good or satisfactory; 66% found it to be similar or better than 12 months earlier, and 48% similar or better than their preadmission state. QOL measures by RAND-36 revealed that aging decreased their competencies most in physical functioning, physical role limitations, and vitality, but the elderly had better values in mental health than the controls. However, QALYs of the elderly respondents were 21% to 35% lower than the mean QALY minus 2 sd units of the age- and gender-adjusted general population. CONCLUSIONS High age alone is not a valid reason to refuse intensive care, but the benefits perceived by intensive care seem to decrease with aging, if reflected as QALYs. However, 97% of the elderly survivors lived at home and 88% of them considered their QOL satisfactory or good after hospital discharge. Therefore, more reliable information on the outcome for the elderly is clearly needed.

negative: Economic implications of nighttime attending intensivist coverage in a medical intensive care unit. OBJECTIVE Our objective was to assess the cost implications of changing the intensive care unit staffing model from on-demand presence to mandatory 24-hr in-house critical care specialist presence. DESIGN A pre-post comparison was undertaken among the prospectively assessed cohorts of patients admitted to our medical intensive care unit 1 yr before and 1 yr after the change. Our data were stratified by Acute Physiology and Chronic Health Evaluation III quartile and whether a patient was admitted during the day or at night. Costs were modeled using a generalized linear model with log-link and γ-distributed errors. SETTING A large academic center in the Midwest. PATIENTS All patients admitted to the adult medical intensive care unit on or after January 1, 2005 and discharged on or before December 31, 2006. Patients receiving care under both staffing models were excluded. INTERVENTION Changing the intensive care unit staffing model from on-demand presence to mandatory 24-hr in-house critical care specialist presence. MEASUREMENTS AND MAIN RESULTS Total cost estimates of hospitalization were calculated for each patient starting from the day of intensive care unit admission to the day of hospital discharge. Adjusted mean total cost estimates were 61% lower in the post period relative to the pre period for patients admitted during night hours (7 pm to 7 am) who were in the highest Acute Physiology and Chronic Health Evaluation III quartile. No significant differences were seen at other severity levels. The unadjusted intensive care unit length of stay fell in the post period relative to the pre period (3.5 vs. 4.8) with no change in non-intensive care unit length of stay. CONCLUSIONS We find that 24-hr intensive care unit intensivist staffing reduces lengths of stay and cost estimates for the sickest patients admitted at night. The costs of introducing such a staffing model need to be weighed against the potential total savings generated for such patients in smaller intensive care units, especially ones that predominantly care for lower-acuity patients.

negative: Hospital volume and the outcomes of mechanical ventilation. BACKGROUND An increased volume of patients is associated with improved survival in numerous high-risk medical and surgical conditions. The relationship between the number of patients admitted (hospital volume) and outcome among patients with critical illnesses is unknown. METHODS We analyzed data from 20,241 nonsurgical patients receiving mechanical ventilation at 37 acute care hospitals in the Acute Physiology and Chronic Health Evaluation clinical information system from 2002 through 2003. Multivariate analyses were performed to adjust for the severity of illness and other differences in the case mix. RESULTS An increase in hospital volume was associated with improved survival among patients receiving mechanical ventilation in the intensive care unit (ICU) and in the hospital. Admission to a hospital in the highest quartile according to volume (i.e., >400 patients receiving mechanical ventilation per year) was associated with a 37 percent reduction in the adjusted odds of death in the ICU as compared with admission to hospitals in the lowest quartile (< or =150 patients receiving mechanical ventilation per year, P<0.001). In-hospital mortality was similarly reduced (adjusted odds ratio, 0.66; 95 percent confidence interval, 0.52 to 0.83; P<0.001). A typical patient in a hospital in a low-volume quartile would have an adjusted in-hospital mortality of 34.2 percent as compared with 25.5 percent in a hospital in a high-volume quartile. Among survivors, there were no significant trends in the length of stay in the ICU or the hospital. CONCLUSIONS Mechanical ventilation of patients in a hospital with a high case volume is associated with reduced mortality. Further research is needed to determine the mechanism of the relationship between volume and outcome among patients with a critical illness.

negative: Geographical access to healthcare in Northern England and post-mortem diagnosis of cancer. BACKGROUND There is some previous evidence that diagnosis of cancer at death, recorded as registry death certificate only records, is associated with problems of access to care. METHODS Records from the Northern and Yorkshire Cancer Registry for patients registered with breast, colorectal, lung, ovarian or prostate cancer between 1994 and 2002 were supplemented with measures of travel time to general practitioner and hospital services, and social deprivation. Logistic regression was used to identify predictors of records where diagnosis was at death. RESULTS There was no association between the odds diagnosis at death and access to primary care. For all sites except breast, the highest odds of being a cancer diagnosed at death fell among those living in the highest quartile of hospital travel time, although it was only statistically significant for colorectal and ovary tumours. Those in the most deprived and furthest travel time to hospital quartile were 2.6 times more likely to be a diagnosis at death case compared with those in the most affluent and proximal areas. CONCLUSIONS There is some evidence that poorer geographical access to tertiary care, in particular when coupled with social disadvantages, may be associated with increased odds of diagnosis at death.

negative: Home birth and barriers to referring women with obstetric complications to hospitals: a mixed-methods study in Zahedan, southeastern Iran BACKGROUND One factor that contributes to high maternal mortality in developing countries is the delayed use of Emergency Obstetric-Care (EmOC) facilities. The objective of this study was to determine the factors that hinder midwives and parturient women from using hospitals when complications occur during home birth in Sistan and Baluchestan province, Iran, where 23% of all deliveries take place in non- hospital settings. METHODS In the study and data management, a mixed-methods approach was used. In the quantitative phase, we compared the existing health-sector data with World Health Organization (WHO) standards for the availability and use of EmOC services. The qualitative phase included collection and analysis of interviews with midwives and traditional birth attendants and twenty-one in-depth interviews with mothers. The data collected in this phase were managed according to the principles of qualitative data analysis. RESULTS The findings demonstrate that three distinct factors lead to indecisiveness and delay in the use of EmOC by the midwives and mothers studied. Socio-cultural and familial reasons compel some women to choose to give birth at home and to hesitate seeking professional emergency care for delivery complications. Apprehension about being insulted by physicians, the necessity of protecting their professional integrity in front of patients and an inability to persuade their patients lead to an over-insistence by midwives on completing deliveries at the mothers' homes and a reluctance to refer their patients to hospitals. The low quality and expense of EmOC and the mothers' lack of health insurance also contribute to delays in referral. CONCLUSIONS Women who choose to give birth at home accept the risk that complications may arise. Training midwives and persuading mothers and significant others who make decisions about the value of referring women to hospitals at the onset of life-threatening complications are central factors to increasing the use of available hospitals. The hospitals must be safe, comfortable and attractive environments for parturition and should give appropriate consideration to the ethical and cultural concerns of the women. Appropriate management of financial and insurance-related issues can help midwives and mothers make a rational decision when complications arise.

negative: "We charge them; otherwise we cannot run the hospital" front line workers, clients and health financing policy implementation gaps in Ghana. OBJECTIVES This paper examines policy implementation gaps of user fees plus exemptions and health insurance in providing financial access to primary clinical care for children under five in Ghana. METHODS Methods included analysis of routine data, focus group discussions, in-depth interviews, and administration of a structured questionnaire. RESULTS Providers modified exemptions policy implementation arrangements, sometimes giving partial or no exemptions. Clients who knew or suspected exemption entitlements failed to request them because of fear of negative reactions from providers. Providers attributed their modification of implementation arrangements and negative reactions to the threat posed to the financial viability of their institutions by reimbursement uncertainty and delays. At the time of the study insurance coverage was low and frontline workers were not noticeably modifying implementation arrangements. However, the underlying goal conflicts, resource scarcity, conditions of work and relationships between frontline workers and clients that fueled the exemptions policy implementation gaps were unchanged. The potential for the health insurance policy to stumble over implementation gaps as happened with the exemptions policy therefore remained. CONCLUSIONS Policies that do not take into account the incentives for frontline worker adherence and align them better with policy objectives may experience implementation gaps.

negative: Care Seeking for Neonatal Illness in Low- and Middle-Income Countries: A Systematic Review BACKGROUND Despite recent achievements to reduce child mortality, neonatal deaths continue to remain high, accounting for 41% of all deaths in children under five years of age worldwide, of which over 90% occur in low- and middle-income countries (LMICs). Infections are a leading cause of death and limitations in care seeking for ill neonates contribute to high mortality rates. As estimates for care-seeking behaviors in LMICs have not been studied, this review describes care seeking for neonatal illnesses in LMICs, with particular attention to type of care sought. METHODS AND FINDINGS We conducted a systematic literature review of studies that reported the proportion of caregivers that sought care for ill or suspected ill neonates in LMICs. The initial search yielded 784 studies, of which 22 studies described relevant data from community household surveys, facility-based surveys, and intervention trials. The majority of studies were from South Asia (n = 17/22), set in rural areas (n = 17/22), and published within the last 4 years (n = 18/22). Of the 9,098 neonates who were ill or suspected to be ill, 4,320 caregivers sought some type of care, including care from a health facility (n = 370) or provider (n = 1,813). Care seeking ranged between 10% and 100% among caregivers with a median of 59%. Care seeking from a health care provider yielded a similar range and median, while care seeking at a health care facility ranged between 1% and 100%, with a median of 20%. Care-seeking estimates were limited by the few studies conducted in urban settings and regions other than South Asia. There was a lack of consistency regarding illness, care-seeking, and care provider definitions. CONCLUSIONS There is a paucity of data regarding newborn care-seeking behaviors; in South Asia, care seeking is low for newborn illness, especially in terms of care sought from health care facilities and medically trained providers. There is a need for representative data to describe care-seeking patterns in different geographic regions and better understand mechanisms to enhance care seeking during this vulnerable time period.

negative: Gender differences in the utilization of health care services. BACKGROUND Studies have shown that women use more health care services than men. We used important independent variables, such as patient sociodemographics and health status, to investigate gender differences in the use and costs of these services. METHODS New adult patients (N = 509) were randomly assigned to primary care physicians at a university medical center. Their use of health care services and associated charges were monitored for 1 year of care. Self-reported health status was measured using the Medical Outcomes Study Short Form-36 (SF-36). We controlled for health status, sociodemographic information, and primary care physician specialty in the statistical analyses. RESULTS Women had significantly lower self-reported health status and lower mean education and income than men. Women had a significantly higher mean number of visits to their primary care clinic and diagnostic services than men. Mean charges for primary care, specialty care, emergency treatment, diagnostic services, and annual total charges were all significantly higher for women than men; however, there were no differences for mean hospitalizations or hospital charges. After controlling for health status, sociodemographics, and clinic assignment, women still had higher medical charges for all categories of charges except hospitalizations. CONCLUSIONS Women have higher medical care service utilization and higher associated charges than men. Although the appropriateness of these differences was not determined, these findings have implications for health care.

negative: An administrative claims measure suitable for profiling hospital performance on the basis of 30-day all-cause readmission rates among patients with heart failure. BACKGROUND Readmission soon after hospital discharge is an expensive and often preventable event for patients with heart failure. We present a model approved by the National Quality Forum for the purpose of public reporting of hospital-level readmission rates by the Centers for Medicare & Medicaid Services. METHODS AND RESULTS We developed a hierarchical logistic regression model to calculate hospital risk-standardized 30-day all-cause readmission rates for patients hospitalized with heart failure. The model was derived with the use of Medicare claims data for a 2004 cohort and validated with the use of claims and medical record data. The unadjusted readmission rate was 23.6%. The final model included 37 variables, had discrimination ranging from 15% observed 30-day readmission rate in the lowest predictive decile to 37% in the upper decile, and had a c statistic of 0.60. The 25th and 75th percentiles of the risk-standardized readmission rates across 4669 hospitals were 23.1% and 24.0%, with 5th and 95th percentiles of 22.2% and 25.1%, respectively. The odds of all-cause readmission for a hospital 1 standard deviation above average was 1.30 times that of a hospital 1 standard deviation below average. State-level adjusted readmission rates developed with the use of the claims model are similar to rates produced for the same cohort with the use of a medical record model (correlation, 0.97; median difference, 0.06 percentage points). CONCLUSIONS This claims-based model of hospital risk-standardized readmission rates for heart failure patients produces estimates that may serve as surrogates for those derived from a medical record model.

negative: Use of health services by prison inmates: comparisons with the community. The future organisation of prison health care 1 recommends that the NHS and the Prison Service work together to plan and provide health care services for prisoners. Whereas previously the Prison Service had this responsibility alone. The NHS will therefore have to take stock of the current level at which prison health care is demanded and provided. A key part of the information base for joint planning therefore includes data on current service utilisation. This paper compares primary care and inpatient health service utilisation data for UK prisoners with health services utilisation data for equivalent community populations. In the community, primary care is provided principally by general practitioners and professions allied to medicine (mostly nurses). Residents in the community have access to the full range of NHS outpatient and inpatient facilities. Within prisons, primary care is provided by medical officers (some of whom are general practitioners), nursing grades and health care officers (who have received some training in health care). Some prisons have their own inpatient facilities (health care centre beds). These provide a low level of inpatient care and do not have a direct equivalent in the community. Prisoners also have access to NHS outpatient and inpatient facilities and to visiting specialists. The prison population has a high turnover and varies from day to day. Because of this, the prison population is expressed as an average daily population during a one year period. …

negative: Screening for concomitant diseases in peripheral vascular patients. Results of a systematic approach. BACKGROUND Patients considered for arterial surgery, have been shown to have a high incidence of coexistent cardiac, vascular and other diseases, affecting operative risk and survival. We developed a systematic workup strategy for detecting these coexistent diseases in our vascular surgical patients, mainly based on non-invasive diagnostic techniques. METHODS We evaluated 200 consecutive patients, admitted to the department of vascular surgery in an academic teaching hospital, in order to establish the total incidence of relevant concomitant disorders, the extent to which this screening yielded previously unknown diagnostic information, and the impact on short-term (one year) survival. RESULTS Coronary artery disease was present in 46% of the patients; 22% had active ischaemia, newly diagnosed in 5.5%. Impaired cardiac function was found in 37%: severely impaired in 12%, newly diagnosed in 27%. Carotid artery disease was present in 32%: critical stenoses were found in 9%; new diagnoses in 29.9%. Aortic aneurysms were present in 7%, newly diagnosed in 5%. Severe renal artery stenosis was present in 5%, newly diagnosed in 3.5%. Sixteen % of the patients had chronic obstructive pulmonary disease, newly diagnosed in 3.5%, and 4.5% had unexpected disorders, which were all new diagnoses. Overall, new diagnoses were reached in 64.5% of the population, affecting therapeutic strategy immediately in 21% of the patients. The presence of coronary artery disease and of cardiac failure were clearly related to one year survival. CONCLUSIONS We conclude that a systematic screening strategy, mainly based on noninvasive techniques, can detect the presence of concomitant diseases in the vascular surgical patient. Most important seem the newly diagnosed diseases altering surgical management in one out of every five patients; they also have important implications for patient prognosis.

negative: The impact of open versus closed format ICU admission practices on the outcome of high risk surgical patients: a cohort analysis BACKGROUND In the year 2000, the organizational structure of the ICU in the Zaandam Medical Centre (ZMC) changed from an open to a closed format ICU. The objective of this study was to evaluate the effect of this organizational change on outcome in high risk surgical patients. METHODS The medical records of all consecutive high risk surgical patients admitted to the ICU from 1996 to 1998 (open format) and from 2003 to 2005 (closed format), were reviewed. High-risk patients were defined according to the Identification of Risk in Surgical patients (IRIS) score. Parameters studied were: mortality, morbidity, ICU length of stay (LOS) and hospital LOS. RESULTS Mortality of ICU patients was 25.7% in the open format group and 15.8% in the closed format group (p = 0.01). Morbidity decreased from 48.6% to 46.1% (p = 0.6). The average length of hospital stay was 17 days in the open format group, and 21 days in the closed format group (p = 0.03). CONCLUSIONS High risk surgical patients in the ICU are patients that have undergone complex and often extensive surgery. These patients are in need of specialized treatment and careful monitoring for maximum safety and optimal care. Our results suggest that closed format is a more favourable setting than open format to minimize the effects of high risk surgery, and to warrant safe outcome in this patient group.

negative: A brief analysis of clinical pharmacy interventions undertaken in an Australian teaching hospital. Selected clinical pharmacy interventions undertaken during a 30-day data capture period were analysed, seeking to gain a greater understanding of the nature of the drug-related problems involved. Pharmacists were asked to record only interventions that were of potentially major significance. A total of 67 interventions were submitted for analysis. In 28 cases (41.7% of the initial total) the intervention reports were excluded from further analysis after initial review. For the remaining 39 interventions, 20 patients (51%) were under the care of a medical unit, and cardiovascular/antithrombotic agents accounted for 17 reports (43.5%). The majority of interventions were implemented at the time of inpatient medication order review by the clinical pharmacist (n=25, 64%). The most common category of drug-related problem addressed in the interventions related to the prescription of inappropriately high doses of the correct drug for the patient (n=17, 43.6%). Deficiencies in technical knowledge accounted for less than 25% of all cases.

negative: Adult T-cell leukemia/lymphoma in London: clinical experience of 21 cases. Adult T-cell leukemia/lymphoma (ATLL) is uncommon in the United Kingdom and has so far been restricted to people of Afro-Caribbean extraction. Between 1981 and 1995, 21 cases presented to 2 inner London teaching hospitals where 17% of the population are of Afro-Caribbean origin. Clinical presentations were similar to those of the disease in HTLV-I-endemic areas. Major responses (CR + PR) were obtained in 10/16 assessable patients (63%) treated with combination chemotherapy. However, median survival was only 5.5 months. Disease progression and opportunistic infection were the major causes of treatment failure and death. Three patients (14%) relapsed in the central nervous system (CNS). Our cases confirm the profound immunosuppression in ATLL. The poor prognosis of acute and lymphoma types of ATLL highlight the need for new approaches to treatment such as zidovudine and alpha-interferon, incorporating prophylaxis against CNS disease and opportunistic infections.

negative: Why do general practitioners prescribe antibiotics for upper respiratory tract infections to meet patient expectations: a mixed methods study OBJECTIVES To describe the role patient expectations play in general practitioners (GPs) antibiotic prescribing for upper respiratory tract infections (URTI). METHODS Concurrent explanatory mixed methods approach using a cross-sectional survey and semistructured interviews. SETTINGS Primary care GPs in Australia. PARTICIPANTS 584 GPs (response rate of 23.6%) completed the cross-sectional survey. 32 GPs were interviewed individually. OUTCOME MEASURE Prescribing of antibiotics for URTI. RESULTS More than half the GP respondents to the survey in Australia self-reported that they would prescribe antibiotics for an URTI to meet patient expectations. Our qualitative findings suggest that 'patient expectations' may be the main reason given for inappropriate prescribing, but it is an all-encompassing phrase that includes other reasons. These include limited time, poor doctor-patient communication and diagnostic uncertainty. We have identified three role archetypes to explain the behaviour of GPs in reference to antibiotic prescribing for URTIs. The main themes emerging from the qualitative component was that many GPs did not think that antibiotic prescribing in primary care was responsible for the development of antibiotic resistance nor that their individual prescribing would make any difference in light of other bigger issues like hospital prescribing or veterinary use. For them, there were negligible negative consequences from their inappropriate prescribing. CONCLUSIONS There is a need to increase awareness of the scope and magnitude of antibiotic resistance and the role primary care prescribing plays, and of the contribution of individual prescribing decisions to the problem of antibiotic resistance.

negative: Noninvasive ventilation for treatment of acute respiratory failure in patients undergoing solid organ transplantation: a randomized trial. CONTEXT Noninvasive ventilation (NIV) has been associated with lower rates of endotracheal intubation in populations of patients with acute respiratory failure. OBJECTIVE To compare NIV with standard treatment using supplemental oxygen administration to avoid endotracheal intubation in recipients of solid organ transplantation with acute hypoxemic respiratory failure. DESIGN AND SETTING Prospective randomized study conducted at a 14-bed, general intensive care unit of a university hospital. PATIENTS Of 238 patients who underwent solid organ transplantation from December 1995 to October 1997, 51 were treated for acute respiratory failure. Of these, 40 were eligible and 20 were randomized to each group. INTERVENTION Noninvasive ventilation vs standard treatment with supplemental oxygen administration. MAIN OUTCOME MEASURES The need for endotracheal intubation and mechanical ventilation at any time during the study, complications not present on admission, duration of ventilatory assistance, length of hospital stay, and intensive care unit mortality. RESULTS The 2 groups were similar at study entry. Within the first hour of treatment, 14 patients (70%) in the NIV group, and 5 patients (25%) in the standard treatment group improved their ratio of the PaO2 to the fraction of inspired oxygen (FIO2). Over time, a sustained improvement in PaO2 to FIO2 was noted in 12 patients (60%) in the NIV group, and in 5 patients (25%) randomized to standard treatment (P = .03). The use of NIV was associated with a significant reduction in the rate of endotracheal intubation (20% vs 70%; P = .002), rate of fatal complications (20% vs 50%; P = .05), length of stay in the intensive care unit by survivors (mean [SD] days, 5.5 [3] vs 9 [4]; P = .03), and intensive care unit mortality (20% vs 50%; P = .05). Hospital mortality did not differ. CONCLUSIONS These results indicate that transplantation programs should consider NIV in the treatment of selected recipients of transplantation with acute respiratory failure.

negative: Ethnographic study of incidence and severity of intravenous drug errors. OBJECTIVES To determine the incidence and clinical importance of errors in the preparation and administration of intravenous drugs and the stages of the process in which errors occur. DESIGN Prospective ethnographic study using disguised observation. PARTICIPANTS Nurses who prepared and administered intravenous drugs. SETTING 10 wards in a teaching and non-teaching hospital in the United Kingdom. MAIN OUTCOME MEASURES Number, type, and clinical importance of errors. RESULTS 249 errors were identified. At least one error occurred in 212 out of 430 intravenous drug doses (49%, 95% confidence interval 45% to 54%). Three doses (1%) had potentially severe errors, 126 (29%) potentially moderate errors, and 83 (19%) potentially minor errors. Most errors occurred when giving bolus doses or making up drugs that required multiple step preparation. CONCLUSIONS The rate of intravenous drug errors was high. Although most errors would cause only short term adverse effects, a few could have been serious. A combination of reducing the amount of preparation on the ward, training, and technology to administer slow bolus doses would probably have the greatest effect on error rates.

negative: Clinical outcomes following institution of the Canadian universal leukoreduction program for red blood cell transfusions. CONTEXT A number of countries have implemented a policy of universal leukoreduction of their blood supply, but the potential role of leukoreduction in decreasing postoperative mortality and infection is unclear. OBJECTIVE To evaluate clinical outcomes following adoption of a national universal prestorage leukoreduction program for blood transfusions. DESIGN, SETTING, AND POPULATION Retrospective before-and-after cohort study conducted from August 1998 to August 2000 in 23 academic and community hospitals throughout Canada, enrolling 14 786 patients who received red blood cell transfusions following cardiac surgery or repair of hip fracture, or who required intensive care following a surgical intervention or multiple trauma. INTERVENTION Universal prestorage leukoreduction program introduced by 2 Canadian blood agencies. A total of 6982 patients were enrolled during the control period and 7804 patients were enrolled following prestorage leukoreduction. MAIN OUTCOME MEASURES All-cause in-hospital mortality and serious nosocomial infections (pneumonia, bacteremia, septic shock, all surgical site infections) occurring after first transfusion and at least 2 days after index procedure or intensive care unit admission. Secondary outcomes included rates of posttransfusion fever and antibiotic use. RESULTS Unadjusted in-hospital mortality rates were significantly lower following the introduction of leukoreduction compared with the control period (6.19% vs 7.03%, respectively; P =.04). Compared with the control period, the adjusted odds of death following leukoreduction were reduced (odds ratio [OR], 0.87; 95% confidence interval [CI], 0.75-0.99), but serious nosocomial infections did not decrease (adjusted OR, 0.97; 95% CI, 0.87-1.09). The frequency of posttransfusion fevers decreased significantly following leukoreduction (adjusted OR, 0.86; 95% CI, 0.79-0.94), as did antibiotic use (adjusted OR, 0.90; 95% CI, 0.82-0.99). CONCLUSION A national universal leukoreduction program is potentially associated with decreased mortality as well as decreased fever episodes and antibiotic use after red blood cell transfusion in high-risk patients.

negative: What do medical schools teach about women's health and gender differences? PURPOSE To examine the curricula of U.S. medical schools to assess the inclusion of women's health and gender-specific information and identify institutional characteristics associated with this content. METHOD Using data from the Association of American Medical Colleges' Curriculum Management and Information Tool (CurrMIT), in November 2003 to February 2004 the authors performed a curriculum search of schools that entered course/clerkships in CurrMIT to identify interdisciplinary women's health or gender-specific courses/clerkships. A subset of schools that entered comprehensive information in CurrMIT was searched for a specified list of women's health topics and or gender-specific content on any topic. Statistical analyses were performed to assess the relationship between frequency of topics and school characteristics. RESULTS The authors identified 95 schools that entered related courses/clerkships. Ten courses/clerkships at nine schools met criteria for an interdisciplinary women's health course/clerkship. In the subset of 60 schools with comprehensive CurrMIT information, 18 specified women's health topics were identified, as well as 24 topics on gender-specific content, for a total of 42 topics. The number of topics taught ranged from zero to 26 (mean = 11). More than 50% of these schools taught 11 of the 18 specified topics, while fewer than 30% included gender-specific topics. There was no association in bivariate analysis between the mean number of topics taught and schools' characteristics; however, a women's health program (p= .01) and female dean (p= .06) were positively associated in a regression model. CONCLUSIONS Few schools offer interdisciplinary women's health courses/clerkships or include gender-specific information in their curricula. A designated women's health program may increase this content in schools' curricula.

negative: Costs and cost-effectiveness of alternative tuberculosis management strategies in South Africa--implications for policy. OBJECTIVE To conduct an economic analysis of the Hlabisa community-based directly observed therapy management strategy for tuberculosis and to project costs of three alternative strategies. SETTING Hlabisa health district, KwaZulu-Natal, South Africa. METHODS An economic analysis comparing the current tuberculosis management strategy in Hlabisa with three alternative strategies (the Hlabisa strategy prior to 1991 based on hospitalisation, the national strategy and sanatorium care) in terms of costs to both health service and patient and of cost-effectiveness. RESULTS The current Hlabisa strategy was the most cost-effective (R3799 per patient cured), compared with R98307 for the strategy used prior to 1991, R9940 for the national strategy, and R11145 for sanatorium care. Between 71% and 88% of treatment costs lie with the health service, and hospitalisation (R119 per day) is the most expensive item. Prolonged hospitalisation is extremely expensive, but community care is cheaper (community clinic visit, R28; community health worker visit, R7). The total cost of supervising a patient in the community under the current Hlabisa strategy was R503, equivalent to 4.2 days in hospital. Drug costs (R157) are equivalent to just 1.3 days in hospital. CONCLUSION Cost to both health service and patient can be substantially reduced by using community-based directly observed therapy for tuberculosis, a strategy that is cheap and cost-effective in Hlabisa. These findings have important national implications, supporting the goals of the new tuberculosis control programme.

negative: Research in cardiovascular care: a position statement of the Council on Cardiovascular Nursing and Allied Professionals of the European Society of Cardiology. To deliver optimal patient care, evidence-based care is advocated and research is needed to support health care staff of all disciplines in deciding which options to use in their daily practice. Due to the increasing complexity of cardiac care across the life span of patients combined with the increasing opportunities and challenges in multidisciplinary research, the Science Committee of the Council on Cardiovascular Nursing and Allied Professionals (CCNAP) recognised the need for a position statement to guide researchers, policymakers and funding bodies to contribute to the advancement of the body of knowledge that is needed to further improve cardiovascular care. In this paper, knowledge gaps in current research related to cardiovascular patient care are identified, upcoming challenges are explored and recommendations for future research are given.

negative: The missing cases of tuberculosis in Malawi: the contribution from cross-border registrations. Low case detection rates of new smear-positive pulmonary tuberculosis (PTB) patients globally are a cause for concern. The aim of this study was to determine for patients registered for TB in Malawi the number and percentage who lived in a neighbouring country and the registration, recording and reporting practices for these 'foreign' patients. All 44 non-private hospitals, which register and treat all TB patients in the public health sector in Malawi, were visited. Ten (23%) hospitals in 2001 and 14 (32%) in 2002 maintained a separate register for cross-border TB cases. Patients recorded in these registers were not formally reported to the Malawi National TB Programme (NTP), the neighbouring country's NTP, nor to WHO. They therefore constitute missing cases. In Malawi, the number of cross-border new smear-positive PTB cases was 77 in 2001 and 91 in 2002, constituting about 3% of missing smear-positive cases in those hospitals that maintain cross-border registers and about 1% of missing cases nationally.

negative: Contribution of traditional healers to a rural tuberculosis control programme in Hlabisa, South Africa. SETTING The rural health district of Hlabisa, KwaZulu-Natal, South Africa.   OBJECTIVES To assess the acceptability and effectiveness of traditional healers as supervisors of tuberculosis (TB) treatment in an existing directly observed treatment, short-course (DOTS) programme. DESIGN An observational study comparing treatment outcomes among new TB patients in the three intervention sub-districts offered the additional option of traditional healers for directly observed treatment (DOT) supervision with those in the remainder of the district offered the standard range of options for DOT supervision (health facility, community health worker and lay persons). A comparison was also made of treatment outcomes between different options for DOT supervision. RESULTS A total of 3461 TB patients were registered in Hlabisa District from April 1999 to December 2000, of whom 2823 were discharged from hospital to the ambulatory DOT programme. Treatment outcomes were known for 1816 patients in Hlabisa District (275 patients in the intervention area and 1541 patients in the control area). There was no significant difference (P < 0.5) in treatment outcome in the intervention and control areas (77% vs. 75%). Among 275 patients with known outcomes in the intervention area, 48 patients were supervised by traditional healers and 227 patients supervised by people other than traditional healers. Treatment completion was not significantly higher among patients supervised by traditional healers than among patients supervised by other categories of DOT supervisor (88% vs. 75%, P = 0.3841). Interviews with 41 of 51 traditional healer patients who had completed treatment revealed high levels of satisfaction with the care received. CONCLUSIONS Traditional healers make an effective contribution to TB programme performance in this pilot scheme in Hlabisa district. Further evaluation will be necessary as this approach is scaled up.

negative: The effectiveness of right heart catheterization in the initial care of critically ill patients. SUPPORT Investigators. OBJECTIVE To examine the association between the use of right heart catheterization (RHC) during the first 24 hours of care in the intensive care unit (ICU) and subsequent survival, length of stay, intensity of care, and cost of care. DESIGN Prospective cohort study. SETTING Five US teaching hospitals between 1989 and 1994. SUBJECTS A total of 5735 critically ill adult patients receiving care in an ICU for 1 of 9 prespecified disease categories. MAIN OUTCOME MEASURES Survival time, cost of care, intensity of care, and length of stay in the ICU and hospital, determined from the clinical record and from the National Death Index. A propensity score for RHC was constructed using multivariable logistic regression. Case-matching and multivariable regression modeling techniques were used to estimate the association of RHC with specific outcomes after adjusting for treatment selection using the propensity score. Sensitivity analysis was used to estimate the potential effect of an unidentified or missing covariate on the results. RESULTS By case-matching analysis, patients with RHC had an increased 30-day mortality (odds ratio, 1.24; 95% confidence interval, 1.03-1.49). The mean cost (25th, 50th, 75th percentiles) per hospital stay was $49 300 ($17 000, $30 500, $56 600) with RHC and $35 700 ($11 300, $20 600, $39 200) without RHC. Mean length of stay in the ICU was 14.8 (5, 9, 17) days with RHC and 13.0 (4, 7, 14) days without RHC. These findings were all confirmed by multivariable modeling techniques. Subgroup analysis did not reveal any patient group or site for which RHC was associated with improved outcomes. Patients with higher baseline probability of surviving 2 months had the highest relative risk of death following RHC. Sensitivity analysis suggested that a missing covariate would have to increase the risk of death 6-fold and the risk of RHC 6-fold for a true beneficial effect of RHC to be misrepresented as harmful. CONCLUSION In this observational study of critically ill patients, after adjustment for treatment selection bias, RHC was associated with increased mortality and increased utilization of resources. The cause of this apparent lack of benefit is unclear. The results of this analysis should be confirmed in other observational studies. These findings justify reconsideration of a randomized controlled trial of RHC and may guide patient selection for such a study.

negative: Awake craniotomy with brain mapping as the routine surgical approach to treating patients with supratentorial intraaxial tumors: a prospective trial of 200 cases. OBJECT Awake craniotomy was performed as the standard surgical approach to supratentorial intraaxial tumors, regardless of the involvement of eloquent cortex, in a prospective trial of 200 patients surgically treated by the same surgeon at a single institution. METHODS Patient presentations, comorbid conditions, tumor locations, and the histological characteristics of lesions were recorded. Brain mapping was possible in 195 (97.5%) of 200 patients. The total number of patients sustaining complications was 33 for an overall complication rate of 16.5%. There were two deaths in this series, for a mortality rate of 1%. New postoperative neurological deficits were seen in 13% of the patients, but these were permanent in only 4.5% of them. Complication rates were higher in patients who had gliomas or preoperative neurological deficits and in those who had undergone prior radiation therapy or surgery. No patient who entered the operating room neurologically intact sustained a permanent neurological deficit postoperatively. Of the most recent 50 patients treated, three (6%) required a stay in the intensive care unit, and the median total hospital stay was 1 day. CONCLUSIONS Use of awake craniotomy can result in a considerable reduction in resource utilization without compromising patient care by minimizing intensive care time and total hospital stay. Awake craniotomy is a practical and effective standard surgical approach to supratentorial tumors with a low complication rate, and provides an excellent alternative to craniotomy performed with the patient in the state of general anesthesia because it allows the opportunity for brain mapping and avoids general anesthesia.

negative: Global and regional burden of hospital admissions for severe acute lower respiratory infections in young children in 2010: a systematic analysis BACKGROUND The annual number of hospital admissions and in-hospital deaths due to severe acute lower respiratory infections (ALRI) in young children worldwide is unknown. We aimed to estimate the incidence of admissions and deaths for such infections in children younger than 5 years in 2010. METHODS We estimated the incidence of admissions for severe and very severe ALRI in children younger than 5 years, stratified by age and region, with data from a systematic review of studies published between Jan 1, 1990, and March 31, 2012, and from 28 unpublished population-based studies. We applied these incidence estimates to population estimates for 2010, to calculate the global and regional burden in children admitted with severe ALRI in that year. We estimated in-hospital mortality due to severe and very severe ALRI by combining incidence estimates with case fatality ratios from hospital-based studies. FINDINGS We identified 89 eligible studies and estimated that in 2010, 11·9 million (95% CI 10·3-13·9 million) episodes of severe and 3·0 million (2·1-4·2 million) episodes of very severe ALRI resulted in hospital admissions in young children worldwide. Incidence was higher in boys than in girls, the sex disparity being greatest in South Asian studies. On the basis of data from 37 hospital studies reporting case fatality ratios for severe ALRI, we estimated that roughly 265,000 (95% CI 160,000-450,000) in-hospital deaths took place in young children, with 99% of these deaths in developing countries. Therefore, the data suggest that although 62% of children with severe ALRI are treated in hospitals, 81% of deaths happen outside hospitals. INTERPRETATION Severe ALRI is a substantial burden on health services worldwide and a major cause of hospital referral and admission in young children. Improved hospital access and reduced inequities, such as those related to sex and rural status, could substantially decrease mortality related to such infection. Community-based management of severe disease could be an important complementary strategy to reduce pneumonia mortality and health inequities. FUNDING WHO.

negative: Gender-dependent differences in outcome after the treatment of infection in hospitalized patients. CONTEXT While it is established that management strategies and outcomes differ by gender for many diseases, its effect on infection has not been adequately studied. OBJECTIVE To investigate the role of gender among hospitalized patients treated for infection. DESIGN Observational cohort study conducted during a 26-month period from December 1996 through January 1999. SETTING University-affiliated hospital. PARTICIPANTS A total of 892 patients in the surgical units of the hospital with 1470 consecutive infectious episodes (782 in men and 688 in women). MAIN OUTCOME MEASURES Mortality during hospitalization by gender for infection episodes overall and for specific infectious sites, including lung, peritoneum, bloodstream, catheter, urine, surgical site, and skin/soft tissue. RESULTS Among all infections, there was no significant difference in mortality based on gender (men, 11.1% vs women, 14.2%; P = .07). After logistic regression analysis, factors independently associated with mortality included higher APACHE (Acute Physiology and Chronic Health Evaluation) II score, older age, malignancy, blood transfusion, and diagnosis of infection more than 7 days after admission, but not gender (female odds ratio [OR] for death, 1.32; 95% confidence interval [CI], 0.90-1.94; P = .16). Mortality was higher in women for lung (men, 18% vs women, 34%; P = .002) and soft tissue (men, 2% vs women, 10%; P < or = .05) infection; for other infectious sites, mortality did not differ by gender. Factors associated with mortality due to pneumonia by logistic regression included higher APACHE II score, malignancy, diabetes mellitus, diagnosis of infection more than 7 days after admission, older age, transplantation, and female gender (OR for death, 2.25; 95% CI, 1.17-4.32; P = .02). CONCLUSIONS Although gender may not be predictive of mortality among all infections, women appear to be at increased risk for death from hospital-acquired pneumonia, even after controlling for other comorbidities.

negative: The association of Red cell distribution width and in-hospital mortality in older adults admitted to the emergency department BACKGROUND The objective of the study was to test the hypothesis that elevated red cell distribution width (RDW) at admission increases the risk of mortality in older patients admitted to the emergency department (ED). METHODS We performed a retrospective analysis of patients admitted to the ED between May 2013 and October 2013. We included patients who were older than 65 years who visited the ED with any medical problems. Baseline RDW values were measured at the time of admission to the ED. The primary outcome was all-cause in-hospital mortality. Multivariate logistic analysis was performed. RESULTS A total of 1,990 patients were finally included in this study. The mean age was 75 years (SD 7), and 936 (47 %) subjects were male. The in-hospital mortality rate was 3.76 % (74 patients). RDW values higher in non-survivors than in survivors (15.9 ± 2.5 vs. 13.8 ± 1.7, p < 0.001). Multivariate logistic analysis showed that RDW was associated with all-cause in-hospital mortality after adjusting for other confounding factors. DISCUSSION RDW value at admission is an independent predictor of all-cause in-hospital mortality among patients older than 65 years. After adjustment for multiple confounders, the all-cause in-hospital mortality rate increased by 21.8% for each 1% increase in RDW. CONCLUSION These results show that RDW at admission is associated with in-hospital mortality among patients older than 65. Thus, RDW at admission may represent a surrogate marker of disease severity. We caution against using these findings to aid clinical decision-making process until they are externally validated.
