The push for evidence-based practice is persistent in the public sector—what counts is what works. One central premise for evidence-based practice is the existence of an evidence base; that is, an accumulated and generalizable body of knowledge. Informed by a recent systematic review, we examine the promises and pitfalls of meta-analysis (the statistical workhorse of systematic reviews) as the primary blueprint for cumulative knowledge building in evaluation. This analysis suggests that the statistical assumptions underlying the meta-analytic framework raise issues that, at least in regards to producing generalizable knowledge, may cut even deeper than is suggested by common criticisms. Advancing beyond meta-analysis, we consider alternative approaches for knowledge building and reflect on the implications of these for individual evaluations.

Abstract Background The clinical and surgical procedures are often based on scientifical evidence but 30-40% of patients do not receive treatment according to evidence based medicine. The main aim of this review and meta-analysis is to assess the effectiveness of leadership in healthcare setting. Methods It was conducted a literature research on MEDLINE, Pubmed and Scopus with publication year between 2015 and 2019. The inclusion criteria were studies involving healthcare workers that evaluated effectiveness of opinion leaders in improving behaviour of healthcare workers, according to clinical or patient related outcomes. The quality of studies were assesed with the NHLBI for before after studies and the NOS for other study designs. The effect of leadership was assessed as risk difference for all studies with the exception of cross sectional studies. For the last it was evaluated correlation between leadership level and outcome measurment. Results A total of 3,155 articles were screened and 284 were fully assessed including 22 of them in the final database: 1 randomized trial, 9 cross sectional and 12 before after studies. For the cross-sectional studies there was a correlation of 0.22 (95% CI 0.15-0.28) between leadership level and outcome measurment. In the metaregression analysis the only factor that increased the correlation was private setting (meta regression coefficent =0.52, p = 0.022). The pooled efficacy was 24% (95% CI 10%-17%) for before after studies. Furthermore, a higher effectiveness was revealed in studies conducted on multi professional (24%) than single professional (9%) healthcare workers. Conclusions According to results, the guidelines adherence and task performance increased in a setting with leadership implementation. The leadership effectiveness appears comparable to other strategies as audit and feedback used to implement evidence-based practice in worldwide healthcare. Key messages The translation of evidence into clinical practice is often difficult but this study suggests that leaderhip can had higher effectiveness in multiprofessional healthcare workers and private setting. The effectiveness of leadership in this review suggests that it can be of help in order to make aware healthcare professionals about effectiveness of comply with evidence-based practice.

ABSTRACT The conduct of systematic reviews and meta-analyses are a cornerstone source of information required for evidence-based practice in all medical and allied health professions. Meta-analyses are important in the exercise sciences because, for instance, sometimes many small underpowered studies may suggest the optimal treatment deviates from the generic guidelines that suggest 30 minutes to 60 minutes of moderate intensity aerobic activity 3 to 5 times weekly, supplemented by 1 or more sessions of resistance exercise. A systematic review and meta-analysis can help by combining studies to increase power and provide an answer. The signature method of presenting results of meta-analyses is the forest plot, and an ability to interpret these data and the associated funnel plots are essential to the practice of evidence-based exercise programming. This work describes the processes of systematic review and meta-analysis and informs the reader on how these works may be presented, interpreted, and applied. Some examples from the field of kinesiology and exercise physiology are presented to illustrate how the results of a meta-analysis may influence evidence-based practice.
