Identifying important barriers to recruitment of patients in randomised clinical studies using a questionnaire for study personnel
Open accessAbstract
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 .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
