| Abstract | Background: It is unclear how to disseminate the results of randomised controlled trials effectively to health professionals and policymakers to improve treatment, care or prevention through changing policy and practice. This systematic review examined the effectiveness of different methods of dissemination of clinical research results to professional audiences. Methods: We systematically reviewed the published and grey literature from 2000 to 2022 for studies assessing different approaches for disseminating clinical study results to professional audiences (health professionals, policymakers and guideline developers). Two reviewers assessed potentially relevant full texts for inclusion. We grouped studies by intervention type, synthesising findings using effect direction plots. Outcomes were grouped into out-takes (e.g. awareness, knowledge, understanding), outcomes (e.g. attitude changes) and impact (changes in policy/practice). The quality of evidence was assessed using GRADE. Results: Our search identified 13,264 unique records, of which 416 full texts were assessed for eligibility. Of 60 studies that were identified as eligible for inclusion, 20 evaluated the effectiveness of interventions to disseminate clinical research results (13 RCTs, 2 observational studies, 3 pre- and post-intervention surveys and 2 cross-sectional surveys). Studies were grouped by intervention: 7 studies that involved face-to-face meetings between the target audience and trained educators were classified as 'outreach interventions'; 5 studies that provided a summary format for systematic review findings (e.g. summary of findings tables) were grouped together. There was high certainty evidence of a small beneficial impact of outreach interventions on health and moderate certainty evidence of impact on practice (mostly prescribing). There was no evidence of impact on policy and very low certainty around benefits on outcomes and out-takes. We found no consistent benefits of summary formats for systematic review results on outcomes or out-takes (moderate quality evidence). Other interventions with less evidence are reported in the Additional Materials. Conclusions: Outreach interventions to disseminate clinical research results can lead to changes in practice and improvements in health. However, these interventions can be resource-intensive. Investment is vital to identify and implement effective and cost-effective ways to disseminate results, so that the potential benefits of trials to patients can be realised.
