Strategies to improve recruitment to research studies (review)

This review aims to quantify the effects of strategies to improve participation in research studies. We aimed to find all randomized and quasi-randomized controlled trials of strategies to improve recruitment to research studies. We searched nine electronic databases and manually searched the reference lists of relevant trials. We assessed the eligibility of each trial using pre-defined criteria. Studies that required only questionnaire completion were excluded. We extracted data on the method evaluated, nature of the population, nature of the study to be recruited into, randomisation or quasirandomisation method, allocation concealment, numbers and proportions in each arm. We used risk ratios and their 95 per cent confidence intervals to describe the effects in individual trials, and assessed heterogeneity of these ratios between trials. Because of heterogeneity between trials and within strategies, the results were not synthesised. Trials of monetary incentives, an additional questionnaire at invitation and treatment information on the consent form demonstrated benefit; these specific interventions from individual trials are not easily generalizable. On this evidence, it is not possible to predict the effect most interventions will have on recruitment. Funders and researchers should ensure that the evaluation of recruitment strategies are incorporated into research studies.
