To evaluate the effectiveness of an educational visit to help obstetricians and midwives select and use evidence from a Cochrane database containing 600 systematic reviews.
                Randomised single blind controlled trial with obstetric units allocated to an educational visit or control group.
                25 of the 26 district general obstetric units in two former NHS regions.
                The senior obstetrician and midwife from each intervention unit participated in educational visits. Clinical practices of all staff were assessed in 4508 pregnancies.
                Single informal educational visit by a respected obstetrician including discussion of evidence based obstetrics, guidance on implementation, and donation of Cochrane database and other materials.
                Rates of perineal suturing with polyglycolic acid, ventouse delivery, prophylactic antibiotics in caesarean section, and steroids in preterm delivery, before and 9 months after visits, and concordance of guidelines with review evidence for same marker practices before and after visits.
                Rates varied greatly, but the overall baseline mean of 43% (986/2312) increased to 54% (1189/2196) 9 months later. Rates of ventouse delivery increased significantly in intervention units but not in control units; there was no difference between the two types of units in uptake of other practices. Pooling rates from all 25 units, use of antibiotics in caesarean section and use of polyglycolic acid sutures increased significantly over the period, but use of steroids in preterm delivery was unchanged. Labour ward guidelines seldom agreed with evidence at baseline; this hardly improved after visits. Educational visits cost pound860 each (at 1995 prices).
                There was considerable uptake of evidence into practice in both control and intervention units between 1994 and 1995. Our educational visits added little to this, despite the informal setting, targeting of senior staff from two disciplines, and donation of educational materials. Further work is needed to define cost effective methods to enhance the uptake of evidence from systematic reviews and to clarify leadership and roles of senior obstetric staff in implementing the evidence. To assess the effectiveness of an individualized multicomponent intervention to promote adherence to antiretroviral therapy (ART) in a cohort of HIV-infected individuals with a history of alcohol problems.
                We conducted a randomized controlled trial to compare the usual medical follow-up with an adherence intervention.
                The principal enrolment site was Boston Medical Center, a private, not-for-profit, academic medical institution.
                HIV-infected patients with a history of alcohol problems on ART. A total of 151 were enrolled and 141 (93%) were assessed at follow-up. Intervention: A nurse, trained in motivational interviewing, completed the following over 3 months in four encounters: addressed alcohol problems; provided a watch with a programmable timer to facilitate pill taking; enhanced perception of treatment efficacy; and delivered individually tailored assistance to facilitate medication use.
                Prior 30-day adherence > or =95%, prior 3-day adherence of 100%, CD4 cell count, HIV RNA and alcohol consumption, each at both short- and long-term follow-up.
                At follow-up, no significant differences in medication adherence, CD4 cell count, HIV RNA or alcohol consumption were found (all P values >0.25).
                A multicomponent intervention to enhance adherence among HIV-infected individuals with a history of alcohol problems was not associated with changes in medication adherence, alcohol consumption or markers of HIV disease progression. The failure to change adherence in a group at high risk for poor adherence, despite utilizing an intensive individual-focused patient intervention, supports the idea of addressing medication adherence with supervised medication delivery or markedly simplified dosing regimens. The objective of the study was to evaluate whether providing antiretroviral therapy (ART) integrated in antenatal care (ANC) clinics resulted in a greater proportion of treatment-eligible women initiating ART during pregnancy compared with the existing approach of referral to ART. ANALYSIS DESIGN AND METHODS: The evaluation used a stepped-wedge design and included all HIV-infected, ART-eligible pregnant women in eight public sector clinics in Lusaka district, Zambia. Main outcome indicators were the proportion of treatment-eligible pregnant women enrolling into HIV care within 60 days of HIV diagnosis, and of these, the proportion initiating ART during pregnancy. Adjusted odds ratios (AORs) and confidence intervals (CIs) for enrollment and initiation proportions were estimated through a logistic regression model accounting for clinical site cluster and time effects.
                Between 16 July 2007 and 31 July 2008, 13,917 women started antenatal care more than 60 days before the intervention rollout and constituted the control cohort; 17 619 started antenatal care after ART integrated into ANC and constituted the intervention cohort. Of the 1566 patients found eligible for ART, a greater proportion enrolled while pregnant and within the 60 days of HIV diagnosis in the intervention cohort (376/846, 44.4%) compared with the control cohort (181/716, 25.3%), AOR 2.06, 95% CI (1.27-3.34); and initiated ART while pregnant in the intervention cohort (278/846, 32.9%) compared with the control cohort (103/716, 14.4%), AOR 2.01, 95% CI (1.37-2.95).
                An integrated ART in ANC strategy doubled the proportion of treatment-eligible women initiating ART while pregnant. To determine whether a patient education programme (PE) would improve rates of adherence to a slow acting antirheumatic drug and to assess any subsequent effect on patient outcome.
                A randomly controlled study comprising 100 patients with rheumatoid arthritis (49 control CG; 51 experimental EG) requiring D-penicillamine (DPA). The same practitioner saw patients on seven occasions, for the same length of time. The EG received 7 x 30 minute one to one sessions of PE, while the CG received standard management. The primary measure of adherence was a pharmacological marker (phenobarbitone) encapsulated with the DPA assayed at monthly intervals for six months. Plasma viscosity (PV), C reactive protein, articular index, morning stiffness, and pain score were used to assess outcome.
                454 blood samples were collected and assayed and the pharmacological marker showed the EG to be significantly more adherent on more occasions than the CG (p<0.05). Patterns of adherence over time showed that at 12 weeks 86% (38/44) of those in the EG compared with 64% (29/45) of the CG remained adherent (p=0.01). These trends continued and by the end of the study 85% (29/34) of the EG compared with 55% (23/42) of the CG were taking their DPA as prescribed. Fifteen patients (12 from the EG) experienced side effects requiring study withdrawal and 14 patients requested study withdrawal (two from the EG). On study entry patients in the CG had significantly higher levels of PV than the EG and this remained so throughout the research. However, on completion, the health status of patients in both groups had improved significantly (p<0.01).
                PE significantly increased adherence to DPA and its effects persisted over a period of six months. No additional clinical benefit was detected in the EG in comparison with the CG. The potentially damaging effect of free O(2) radicals to cultured embryos may be reduced by adding scavengers to the culture media or by reducing the incubator O(2) levels. However, lowering the O(2) in the culture environment can be expensive, troublesome and may not be justifiable. The objective of this study was to evaluate the effect of lowered incubator O(2) tension on live birth rates in a predominately Day 5 embryo transfer program.
                Two hundred and thirty first-cycle women undergoing routine IVF or ICSI with ejaculated sperm were randomized in a prospective clinical trial and stratified for patient age and physician. Embryos of patients were randomly assigned for culture in either a 21% O(2) (atmospheric) or 5% O(2) (reduced) environment. Clinical endpoints monitored were rates of implantation, clinical pregnancy, live birth and blastocyst cryopreservation.
                Embryos cultured in a 5% O(2) environment consistently resulted in higher rates of live birth implantation (106/247, 42.9% versus 82/267, 30.7%; difference of 12.2% with 95% confidence interval (CI) of 3.9-20.3, P = 0.005) and live births (66/115, 57.4% versus 49/115, 42.6%; difference of 14.8% with 95% CI of 1.9-27.0, P = 0.043) when compared with rates among women whose embryos were cultured in an atmospheric O(2) environment.
                The overall increase in live births demonstrated by this study indicates that the effort and expense to culture embryos in a low-O(2) environment is justified. The study was registered at clinicaltrials.gov. NCT00708487. (1) To determine the feasibility of a multicentre, randomized, double-masked, placebo-controlled trial to investigate the effects of multiple courses of antenatal corticosteroids (ACS), more than 7 days following the initial course of ACS therapy, on perinatal or neonatal mortality or neonatal morbidity. (2) To determine the risk of complications that would require discontinuation of ACS therapy. (3) To determine if multiple courses of ACS have an effect on the concentrations of plasma cortisol and adrenocorticotropin hormone (ACTH) in cord blood and in maternal blood immediately following delivery, compared to a single course of ACS.
                Women at 24 to 30 weeks' gestation, at continued increased risk of preterm birth 7 or more days following a single course of ACS, were randomized to receive weekly courses of betamethasone or placebo until 33 weeks' gestation or delivery.
                Women were recruited at two hospitals in Toronto from 01 September 1999 to 31 August 2000. Of the 78 women who were approached and were eligible for the study, 12 (15%) were recruited and 66 (85%) refused to participate. Of the 66 refusals, 38 (58%) did not feel their physicians were supportive of the study, 10 (15%) did not want to be randomized, and 4 (6%) had other personal reasons for refusing to enter the trial. Fourteen women (21%) had physicians who did not allow them to join the study. The lack of physician support was due to concerns related to the potential adverse effects of multiple courses of ACS. There were no complications requiring discontinuation of ACS. Plasma cortisol and ACTH concentrations in cord and maternal blood taken after delivery were not significantly different between ACS and placebo groups.
                A multicentre randomized controlled trial is required to determine the benefits and risks of multiple versus a single course of ACS. If the study protocols are supported by physicians and their patients, a multicentre randomized controlled trial is feasible. To compare two prostaglandin (PG) E2 preparations for pre-induction cervical ripening in a randomized clinical trial.
                Two milligrams of vaginal PGE2 gel was compared with a vaginal PGE2 3-mg tablet in 200 nulliparous women. Outcomes assessed were induction failure, need for labor augmentation, pain relief requirements, fetal heart rate (FHR) abnormalities, operative delivery rate, induction-to-delivery interval, neonatal condition, and occurrence of uterine hyperstimulation.
                There was no statistical difference in pre- and post-dose cervical scores. Compared with the tablet group, women in the gel group were more likely to have significant FHR abnormalities in early labor (odds ratio [OR] 4.77, 95% confidence interval [CI] 1.15-19.5) requiring cesarean delivery. Fetal heart rate tracings in the active phase of labor were also more likely to be abnormal in the gel group (chi 2 = 4.31, P < .05). Compared with the gel group, women in the tablet group were significantly more likely to require operative delivery for poor progress in labor (OR 2.83, 95% CI 1.20-7.24). Other clinical outcomes were identical, with no significant differences in the overall rate of failed induction, cesarean delivery, rate of assisted delivery, requirement for oxytocin infusion, induction-to-delivery interval, pain relief requirements, or neonatal condition.
                When compared with the PGE2 tablet, the use of PGE2 gel for cervical ripening and labor induction in nulliparous women did not result in significant improvements in labor outcome. Whereas the gel was associated with an increase in significant FHR abnormalities, the tablet was associated with an increase in the rate of operative delivery for poor progress in labor.
There is evidence of an improved clinical pregnancy rate with the use of adherence compounds in ART cycles but no evidence of an effect on live birth rate. The increase in multiple pregnancy rate may be the result of the use of a combination of an adherence compound and a policy of transferring more than one embryo. Further studies of adherence compounds with single embryo transfer need to be undertaken.
