abstract

  • BACKGROUND: Some population-based recruitment methods, such as registries and databases, have been used to increase enrolment in clinical trials by identifying eligible participants based on baseline characteristics; however; these methods have not been tested in surgical trials, in which accrual occurs before surgery. We evaluated the use of population-based electronic databases to identify patients who potentially could be accrued to the Simultaneous Resection of Colorectal Cancer with Synchronous Liver Metastases (RESECT) trial and compared it to the traditional methods used to accrue patients (e.g., multidisciplinary rounds, letters to community surgeons) for that same trial during the same period. METHODS: An electronic database (ePath) was interrogated every 2 weeks for patients diagnosed with colorectal cancer from Feb. 1, 2017, to Mar. 30, 2019. A radiologic image database (OneView) was reviewed to identify those with liver metastases (level 1 screening). Reports were interrogated to identify potentially eligible patients for the RESECT trial (level 2 screening). A hepatobiliary surgeon reviewed radiology images to identify eligible patients for the trial (level 3 screening). The primary outcome was patient eligibility for the ongoing RESECT trial. RESULTS: The population-based method identified 90 (11.2%) of 803 patients diagnosed with colorectal cancer over the study period. Among the 90 patients, level 2 screening identified 60 (67%) potentially eligible patients for the RESECT trial. Of the 90 patients, 18 (20%) were eligible after radiographic image review (level 3 screening). Traditional accrual methods identified 38 patients with liver metastases, 27 (71%) of whom were identified as potentially eligible on level 2 screening, and 14 (37%) of whom were deemed to be eligible on level 3 screening. Twenty-six patients were identified by both methods. Twelve patients were identified by population-based methods alone, and 8 patients by traditional methods alone. Six eligible patients were identified by both methods. Baseline characteristics were similar between the 2 groups. CONCLUSION: A population-based electronic database method of patient accrual was able to identify eligible participants for the RESECT trial. However, optimal accrual likely requires the use of traditional methods as well.
