Review Meta AnalysisFluphenazine (oral) versus placebo for schizophrenia.
Fluphenazine is one of the first drugs to be classed as an 'antipsychotic' and has been widely available for five decades. ⋯ The findings in this review confirm much that clinicians and recipients of care already know, but they provide quantification to support clinical impression. Fluphenazine's global position as an effective treatment for psychoses is not threatened by the outcome of this review. However, fluphenazine is an imperfect treatment and if accessible, other inexpensive drugs less associated with adverse effects may be an equally effective choice for people with schizophrenia.

Review Meta AnalysisInterventions for implementation of thromboprophylaxis in hospitalized medical and surgical patients at risk for venous thromboembolism.
Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in hospitalized patients. Numerous randomized controlled trials (RCTs) show that using thromboprophylaxis in hospitalized patients at risk for VTE is safe, effective and cost-effective. Despite this, prophylactic therapies for VTE are underutilized. System-wide interventions may be more effective to improve the use of VTE prophylaxis than relying on individual providers' prescribing behaviors. ⋯ We reviewed a large number of studies which implemented a variety of system-wide strategies aimed to improve thromboprophylaxis rates in many settings and patient populations. We found statistically significant improvements in prescription of prophylaxis associated with alerts (RCTs) and multifaceted interventions (RCTs and NRS), and improvements in prescription of appropriate prophylaxis in NRS with the use of education, alerts and multifaceted interventions. Multifaceted interventions with an alert component may be the most effective. Demonstrated sources of heterogeneity included patient types and type of hospital. The results of our review will help physicians, nurses, pharmacists, hospital administrators and policy makers make practical decisions about local adoption of specific system-wide measures to improve prevention of VTE, an important public health issue. We did not find a significant benefit for VTE outcomes; however, earlier RCTs assessing the efficacy of thromboprophylaxis which were powered to address these outcomes have demonstrated the benefit of prophylactic therapies and a favourable balance of benefits versus the increased risk of bleeding events.

Review Meta AnalysisOnce versus twice daily low molecular weight heparin for the initial treatment of venous thromboembolism.
In the initial treatment of venous thromboembolism (VTE) low molecular weight heparin (LMWH) is administered once or twice daily. A once daily treatment regimen is more convenient for the patient and may optimise home treatment. However, it is not clear whether a once daily treatment regimen is as safe and effective as a twice daily treatment regimen. This is the second update of a review first published in 2003. ⋯ Once daily treatment with LMWH is as effective and safe as twice daily treatment with LMWH.

Review Meta AnalysisContinuous support for women during childbirth.
Historically, women have been attended and supported by other women during labour. However, in hospitals worldwide, continuous support during labour has become the exception rather than the routine. ⋯ Continuous support during labour has clinically meaningful benefits for women and infants and no known harm. All women should have support throughout labour and birth.

Review Meta AnalysisRoutine vaginal examinations for assessing progress of labour to improve outcomes for women and babies at term.
Vaginal examinations have become a routine intervention in labour as a means of assessing labour progress. Used at regular intervals, either alone or as a component of the partogram (a pre-printed form providing a pictorial overview of the progress of labour), the aim is to assess if labour is progressing physiologically, and to provide an early warning of slow progress. Abnormally slow progress can be a sign of labour dystocia, which is associated with maternal and fetal morbidity and mortality, particularly in low-income countries where appropriate interventions cannot easily be accessed. However, over-diagnosis of dystocia can lead to iatrogenic morbidity from unnecessary intervention (e.g. operative vaginal birth or caesarean section). It is, therefore, important to establish whether or not the routine use of vaginal examinations is an effective intervention, both as a diagnostic tool for true labour dystocia, and as an accurate measure of physiological labour progress. ⋯ On the basis of women's preferences, vaginal examination seems to be preferred to rectal examination. For all other outcomes, we found no evidence to support or reject the use of routine vaginal examinations in labour to improve outcomes for women and babies. The two studies included in the review were both small, and carried out in high-income countries in the 1990s. It is surprising that there is such a widespread use of this intervention without good evidence of effectiveness, particularly considering the sensitivity of the procedure for the women receiving it, and the potential for adverse consequences in some settings.The effectiveness of the use and timing of routine vaginal examinations in labour, and other ways of assessing progress in labour, including maternal behavioural cues, should be the focus of new research as a matter of urgency. Women's views of ways of assessing labour progress should be given high priority in any future research in this area.
