BACKGROUND: Many randomised controlled trials (RCT) fail to meet their recruitment goals. Study personnel play a key role in recruitment. The aim of this study was to identify successful strategies that study personnel consider to be important in patient recruitment to RCT. METHODS: We constructed a questionnaire based on the literature, discussions with colleagues and our own experience as trialists. The survey was named "What is Important for Making a Study Successful questionnaire" (WIMSS-q). Our target group was the study personnel in the ongoing EFFECTS study. The questionnaire was sent out electronically to all physicians and nurses (n = 148). Success factors and barriers were divided according to patient, centre and study level, respectively. RESULTS: Responses were received from 94% of the study personnel (139/148). The five most important factors at centre level for enhancing recruitment were that the research question was important (97%), a simple procedure for providing information and gaining consent (92%), a highly engaged local principal investigator and research nurse (both 87%), and that study-related follow-ups are practically feasible and possible to coordinate with the clinical follow-up (87%). The most significant barrier at the local centre was lack of time and resources devoted to research (72%). Important patient-related barriers were fear of side effects (35%) and language problems (30%). CONCLUSIONS: For recruitment in an RCT to be successful, the research question must be relevant, and the protocol must be simple and easy to implement in the daily routine. TRIAL REGISTRATION: The protocol for this study was registered at the Northern Ireland Hub for trials methodology research (SWAT ID 64 ). The EFFECTS study has EudraCT number 2011-006130-16 and was registered 17 February 2016 at ClinicalTrials.gov number NCT02683213 .
