The evidence–practice gap in specialist mental healthcare: Systematic review and meta-analysis of guideline implementation studies

Abstract

BackgroundClinical practice guidelines are not easily implemented, leading to a gap between research synthesis and their use in routine care.AimsTo summarise the evidence relating to the impact of guideline implementation on provider performance and patient outcomes in mental healthcare settings, and to explore the performance of different strategies for guideline implementation.MethodA systematic review of randomised controlled trials, controlled clinical trials and before-and-after studies comparing guideline implementation strategies v. usual care, and different guideline implementation strategies, in patients with severe mental illness.ResultsIn total, 19 studies met our inclusion criteria. The studies did not show a consistent positive effect of guideline implementation on provider performance, but a more consistent small to modest positive effect on patient outcomes.ConclusionsGuideline implementation does not seem to have an impact on provider performance, nonetheless it may influence patient outcomes positively.
