Chronic obstructive pulmomary disease (COPD) is associated with substantial mortality, morbidity, and costs to the health care system. With the increasing interest in outreach care programmes it is important to evaluate their impact upon patients and health services, for conditions such as COPD.
                To determine the effectiveness of an outreach respiratory nurse in a shared care approach, with collaboration between general practitioners and hospital services, in the management of patients with severe COPD.
                Patients with severe COPD attending The Queen Elizabeth Hospital, Adelaide participated in a randomised controlled trial of a home based nursing intervention (HBNI) over 12 months with outcome measures including mortality rate, hospital service utilisation, FEV1 and health related quality of life (HRQL) using a modified Dartmouth Primary Care Co-operative Quality of Life questionnaire.
                There were 48 subjects in each study arm, with no differences in mortality rate (eight deaths in the HBNI group and seven in the control group), hospital admissions, length of stay, number of outpatient and Emergency Service visits. The study had inadequate follow-up of FEV1 and HRQL within the control group. Within the HBNI group, a small improvement in HRQL (in three of ten indices measured) was demonstrated, despite a deterioration in FEV1 (11% reduction, p=0.04) compared to baseline. Quality of life of HBNI subjects' carers did not change.
                An increased level of care given by an outreach respiratory nurse in a shared care approach for patients with severe COPD produced small improvements in HRQL but did not result in the prevention of deaths or reduced health care utilisation. A steady increase in chronic obstructive pulmonary disease (COPD) admissions was addressed by enhancing primary care to provide intensive chronic disease management.
                To compare the effect of a disease management programme, including a COPD management guideline, a patient-specific care plan and collaboration between patients, general practitioners, practice nurses, hospital physicians and nurse specialists with conventional care, on hospital admissions and quality of life.
                One hundred and thirty-five patients with a clinical diagnosis of moderate to severe COPD were identified from hospital admission data and general practice records. General practices were randomized to either conventional care (CON), or the intervention (INT). Pre- and post-study assessment included spirometry, Shuttle Walk Test, Short Form-36, and the Chronic Respiratory Questionnaire (CRQ). Admission data were compared for 12 months prior to and during the trial.
                For respiratory conditions, mean hospital bed days per patient per year for the INT group were reduced from 2.8 to 1.1, whereas those for the CON group increased from 3.5 to 4.0 (group difference, P = 0.030) The INT group also showed an improvement for two dimensions of the CRQ, fatigue (P = 0.010) and mastery (P = 0.007).
                A chronic disease management programme for COPD patients that incorporated a variety of interventions, including pulmonary rehabilitation and implemented by primary care, reduced admissions and hospital bed days. Key elements were patient participation and information sharing among healthcare providers. Chronic obstructive pulmonary disease (COPD) patients with chronic ventilatory failure (CVF) are more likely to develop exacerbations, which are an important determinant of health-related quality of life (HRQL). Long-term noninvasive positive-pressure ventilation (NPPV) has been proposed in addition to long-term oxygen therapy (LTOT) to treat CVF but little information is available on its effects on HRQL and resource consumption. Therefore, the current authors undertook a 2-yr multicentric, prospective, randomised, controlled trial to assess the effect of NPPV+ LTOT on: 1) severity of hypercapnia; 2) use of healthcare resources, and 3) HRQL, in comparison with LTOT alone. One hundred and twenty-two stable hypercapnic COPD patients on LTOT for > or = 6 months were consecutively enrolled. After inclusion and 1-month run-in, 90 patients were randomly assigned to NPPV+LTOT (n=43) or to LTOT alone (n=47). Arterial blood gases, hospital and intensive care unit (ICU) admissions, total hospital and ICU length of stay and HRQL were primary outcome measures; survival and drop-out rates, symptoms (dyspnoea and sleep quality) and exercise tolerance were secondary outcome measures. Follow-up was performed at 3-month intervals up to 2 yrs. Lung function, inspiratory muscle function, exercise tolerance and sleep quality score did not change over time in either group. By contrast the carbon dioxide tension in arterial blood on usual oxygen, resting dyspnoea and HRQL, as assessed by the Maugeri Foundation Respiratory Failure Questionnaire, changed differently over time in the two groups in favour of NPPV+LTOT. Hospital admissions were not different between groups during the follow-up. Nevertheless, overall hospital admissions showed a different trend to change in the NPPV+LTOT (decreasing by 45%) as compared with the LTOT group (increasing by 27%) when comparing the follow-up with the follow-back periods. ICU stay decreased over time by 75% and 20% in the NPPV+LTOT and LTOT groups, respectively. Survival was similar. Compared with long-term oxygen therapy alone, the addition of noninvasive positive-pressure ventilation to long-term oxygen therapy in stable chronic obstructive pulmonary disease patients with chronic ventilatory failure: 1) slightly decreased the trend to carbon dioxide retention in patients receiving oxygen at home and 2) improved dyspnoea and health-related quality of life. The results of this study show some significant benefits with the use of nocturnal, home noninvasive positive-pressure ventilation in patients with chronic ventilatory failure due to advanced chronic obstructive pulmonary disease patients. Further work is required to evaluate the effect of noninvasive positive-pressure ventilation on reducing the frequency and severity of chronic obstructive pulmonary disease exacerbation. Whereas pulmonary rehabilitation reduces symptoms and improves the quality of life of patients with COPD and is recommended in management guidelines, few patients have access to rehabilitation services. The purpose of this study was to investigate the effectiveness of increasing access to selected components of pulmonary rehabilitation by providing nurse-assisted home care that was composed of patient education, efforts to improve patient self-management skills, and enhanced follow-up.
                We conducted a 6-month, randomized, controlled trial.
                Primary care clinics associated with an urban academic health system.
                Patients were > or = 45 years of age with a physician diagnosis of COPD, and had a > or = 20-pack-year smoking history, had experienced at least one respiratory symptom during the past 12 months, and had airflow obstruction (ie, FEV1/FVC ratio, < 70%; FEV1, < 80%).
                Four nurses were trained in the use of the Global Initiative for Chronic Obstructive Lung Disease guidelines, and two of the four nurses received additional training in collaborative management. Patients were randomly assigned to usual care (UC), nurse-assisted medical management (MM), or nurse-assisted collaborative management (CM).
                The main outcome measures were of generic (Medical Outcome Study 36-item short form [SF-36], illness intrusiveness) and disease-specific (St. George's respiratory questionnaire [SGRQ]) quality of life and self-reported health-care utilization.
                Overall, 151 patients (UC group, 51 patients; MM group, 49 patients; and CM group, 51 patients) completed the study, their average age was 69 years, and 56.9% were women. The average change in the SF-36 general health domain for the MM group vs the UC group was 1.1 (95% confidence interval [CI], -7.9 to 11.2), and for the CM group vs the UC group the average change was 2.5 (95% CI, -7.0 to 12.3). The corresponding changes in SGRQ total domain were -2.9 (95% CI, -9.8 to 4.1) and -2.6 (95% CI, -9.5 to 4.3). There was no change in the number of self-reported emergency department visits or hospitalizations, but the utilization of these services was infrequent.
                The findings of our investigation and those from the published literature suggest that interventions to enhance patient education, self-management skills, and follow-up among patients with COPD do not result in clinically meaningful improvements in health status or self-reported health-care utilization. Moreover, future studies of disease management programs for patients with COPD need to evaluate interventions that address associated comorbidities, exercise, and social support. This study tests whether an outreach educational program tailored to institutional specific patient care practices would improve the quality of care delivered to mechanically ventilated intensive care unit (ICU) patients in rural hospitals. The study was conducted as a randomized control trial using 20 rural Iowa hospitals as the unit of analysis. Twelve randomly selected hospitals received an outreach educational program. After review of the medical records of eligible patients, a multidisciplinary team of intensive care unit specialists from an academic medical center delivered an educational program with content specific to the findings and capacity of the hospital. The outcome measures included patient care processes, patient morbidity and mortality outcomes, and resource use. Results indicated that the outreach program significantly improved many patient care processes (lab work, nursing, dietary management, ventilator management, ventilator weaning). The program marginally reduced hospital ventilator days. Both total length of stay and ICU length of stay fell markedly in the intervention group (by an average of 3.2 and 2.1 d, respectively), while the control group fell only 0.6 and 0.3 d, respectively. However, these effects did not reach statistical significance. Unfortunately, the program had no detectable effects on the clinical outcomes of mortality or nosocomial events. We conclude that an outreach program of this type can effectively improve processes of care in rural ICUs. However, improving processes of care may not always translate into improvement of specific outcomes. The purpose of this trial was to determine the effectiveness of advanced practice nursing support on cardiac surgery patients' during the first 5 weeks following hospital discharge. Patients ( N = 200) were randomly allocated to two groups: (a) an intervention group who received telephone calls from an advanced practice nurse (APN) familiar with their clinical condition and care needs, twice during the first week following discharge then weekly thereafter for 4 weeks, and (b) a usual care group. Measures of health-related quality of life (HRQL), symptom distress, satisfaction with recovery care, and unexpected health care contacts were obtained at 5 weeks following discharge. There were no significant group differences in HRQL, unexpected contacts with the health care system, or symptom distress. The provision of APN support via telephone followup after cardiac surgery is feasible. However, further randomized trials of single and multicomponent APN interventions are needed to prove effectiveness. An integrated care intervention including education, coordination among levels of care, and improved accessibility, reduced hospital readmissions in chronic obstructive pulmonary disease (COPD) after 1 year. This study analyses the effectiveness of this intervention in terms of clinical and functional status, quality of life, lifestyle, and self-management, under the hypothesis that changes in these factors could explain the observed reduction in readmissions. A total of 113 exacerbated COPD patients (14% female, mean (SD) age 73(8) years, FEV(1) 1.2(0.5) l) were recruited after hospital discharge in Barcelona, Spain, and randomly assigned (1:2) to integrated care (IC) (n=44) or usual care (UC) (n=69). The intervention consisted of an individually tailored care plan at discharge shared with the primary care team and access to a specialized case manager nurse through a web-based call centre. After 1 year of intervention, subjects in the intervention group improved body mass index by 1.34 kg/m(2). Additionally, they scored better in self-management items: COPD knowledge 81% vs. 44%, exacerbation identification 85% vs. 22%, exacerbation early treatment 90% vs. 66%, inhaler adherence 71 vs. 37%, and inhaler correctness 86 vs. 24%. There were no differences in the evolution of dyspnea, lung function, quality of life scores, lifestyle factors, or medical treatment.
                This IC trial improved disease knowledge, and treatment adherence, after 1 year of intervention, suggesting that these factors may play a role in the prevention of severe COPD exacerbations triggering hospital admissions. The effect of patient education in patients with asthma and Chronic Obstructive Pulmonary Disease (COPD) on health-related quality of life (HRQoL) is not previously investigated using the St. George's Respiratory Questionnaire (SGRQ). We randomly allocated at our out-patient clinic 78 asthmatics and 62 patients with COPD to either a control or an intervention group. Intervention consisted of two 2-h group sessions and one to two individual sessions each by a nurse and a physiotherapist. A self-management plan was developed. Baseline quality of life assessment showed comparable scores independent of treatment groups among asthmatics and patients with COPD, but statistically significantly better scores (p < 0.05) for the educated asthma group after 12 mo compared with the control group. This aligned with the 12-mo SGRQ assessment, which revealed better symptoms, activity, impact, and total scores by 11 (p < 0.02), 15 (p < 0.01), 19 (p < 0.001), and 16 (p < 0.001) units, respectively. Patient education among asthmatics increased the FEV1 by a mean value of 6.1% (SD, 12) compared with the control group (p < 0.05). Education among patients with COPD did not indicate a significant increase in HRQoL as measured by the SGRQ or increased FEV1. We conclude that patient education increased HRQoL and FEV1 among asthmatics, but not among patients with COPD.
Outreach nursing programmes for COPD improved disease-specific HRQL. However the effect on hospitalisations was heterogeneous, reducing admissions in one study, but increasing them in others, therefore we could not draw firm conclusions for this outcome.
