Abstract
INTRODUCTION
Locally-initiated research studies in radiation therapy (RT) aim to substantiate clinical processes and are an effective approach to gather evidence for advances in patient care, new techniques, and protocols. The aim of this study was to retrospectively quantify recruitment challenges at a radiation oncology network (RON).
METHODS
Five locally initiated studies were included for analysis through the criteria of being undertaken within 2001-2017, initiated through local research teams, and having recruitment records available. Data extraction from each study included duration, aims, patient activities, recruitment strategy, target number of participants, and number of participants who were recruited/not recruited and who withdrew from the study. Reasons for nonregistration and withdrawal were recorded if available. Two studies are presented as case studies.
RESULTS
Included studies were diverse in patient population and study aim and included patient immobilization (lung and breast cancer), evaluation of radiation-induced esophagitis, documentation of anatomical and dosimetric changes in patients with head and neck cancer, and education (breast cancer). The exclusion of non-English-speaking patients, which is significant for the RON, which covers a wide cultural and linguistic diversity, was an important limiting factor, along with RT patients' disinterest in participation.
DISCUSSION
Challenges experienced in the evaluated RON studies are similar to non-RT clinical trials and included difficulties with patients interacting with study protocol, health practitioners' influence, and patient-related inclusion issues.
CONCLUSION
The resulting database provides a foundation for continued monitoring and documentation of study recruitment practice, which could elicit positive effects on planning and implementation of future patient recruitment strategies in RT locally initiated studies.
