Objectives: To retrospectively analyze feasibility questionnaires to evaluate the number of trials that resulted in patient enrolment and the mean time frame involved.
Methods: This study was conducted by TREAD Research, a site-managed organization based in the Western Cape, South Africa, between January 2004 and December 2009. All feasibility questionnaires received by the site over this time period were analyzed. Descriptive statistics were used to analyze the data.
Results: A total of 252 feasibility questionnaires were received; 207 were accepted and 45 rejected. An average of 26.8% of trials started out of those feasibilities that were accepted by the site. The average time frame from feasibility acceptance to patient enrolment was 12.9 months (range 2.7–33.5 months).
Conclusion: Improving the trial feasibility process would markedly improve a trial site’s ability to plan effectively and efficiently allocate appropriate resources.
