The growth of patient and public involvement in clinical research highlights the paucity of literature on operational practices that ensure the success of large, patient-centered outcomes trials. The authors' objective was to identify tools launched by the Comparison of Intravesical Therapy and Surgery as Treatment Options for Bladder Cancer (CISTO) study team to determine their effectiveness in maximizing patient enrollment in this observational, pragmatic trial.
The primary outcomes for this study were patient screening and enrollment across 36 CISTO study sites. The operational strategies included CISTOquestion email correspondence and All Sites Meetings, specifically poll performance data from meetings, and a nonanonymized feedback survey about the CISTO study's management practices. Effectiveness was measured using correlation analysis with patient cohort data, including screenings, enrollments, post-hoc exclusions, and the post-hoc exclusion rate.
Average screenings and enrollment rose after the implementation of CISTOquestion in April 2021, with the average number of screenings rising from 7.42 to 26.8 patients per month and enrollment rising from 3.76 to 16 patients per month. Use of CISTOquestion was correlated strongly with increased patient screenings and enrollment across all study sites. Eighty-three percent of sites with above-average post-hoc exclusion rates (≥0.092) sent below the average number of CISTOquestion inquiries. Poll performance and survey data revealed that all survey respondents who used CISTOquestion found that it was a valuable and accessible resource.
Of the several operational tools implemented within the CISTO study that aimed to improve patient enrollment, CISTOquestion, a centralized email for addressing eligibility questions, was most beneficial to overall patient accrual.
