Improving the pre-screening of eligible patients in order to increase enrollment in cancer clinical trials

Abstract: BackgroundThe performance of randomized controlled trials (RCTs) is often hindered by recruitment difficulties. This study aims to explore the pre-screening phase of four prostate cancer RCTs to identify the impact of a systematic pre-selection of eligible patients for RCT recruitment.MethodsThe pre-screening of four RCTs opened at the Comprehensive Cancer Center in Rennes was analyzed retrospectively (French Genitourinary Tumor Group (GETUG) 14, 15, 16, and 17). Data were extracted from electronic multidiscip… Show more

“…Routinising pre‐screening of eligible patients in order to increase enrolment in RCTs was one of the suggestions to increase the recruitment rate and routinise RCTs in clinical care . The research and clinical nurses in our study said that they would routinely perform pre‐screening of patients' logs prior to the clinic.…”

“…The researchers highlighted that pre‐screening of eligible patients could be performed prospectively and retrospectively, and practicing both approaches helped to ensure that no eligible patients were missed. Some large centres use semi‐automated pre‐selection, which was found to be effective . There is evidence that the regular use of screening logs would optimise the recruitment …”

“…The extension might be possible by modeling those outcomes with generalized estimating equations or non-linear mixed-effects models although derivations of closed forms could be intractable. For this reason, sample size determinations based on simulation approaches might be preferable as attempted by Baio et al 11 Nonetheless, we suspect that simulation of non-normal data with multi-level data hierarchy for a specified correlation structure would be challenging particularly because correlations may well vary with means on which variances depend unlike normal distributions. Therefore, it would also be interesting to examine if extensions based on normal approximations would be comparable.…”

“…Woertman et al 10 converted Hussey and Hughes’ formula to a design effect of the SW design in comparison with a conventional two parallel arm design. Baio et al 11 also suggested a design effect formula under a different setting and statistical model. Hemming et al 12 evaluated the impact of intra-cluster correlations on statistical power or sample size through design effects under various types of SW designs.…”
