Effects of routine collection of patient-reported outcomes on patient health outcomes in oncology settings: A systematic review

Objective: This study aims to investigate the potential benefits of integrating patient-reported outcomes (PROs) into routine clinical practice for patients undergoing active anticancer treatment. Methods: We conducted a comprehensive systematic review of randomized controlled trials involving cancer patients undergoing active anticancer treatment, spanning various cancer types and stages. The review covered four electronic databases (Medline, EMBASE, Cochrane Library, and CINAHL) up to September 2022. Key in-clusion criteria focused on the incorporation of PROs as a routine intervention. Bias assessment followed the Cochrane collaboration's criteria, while the synthesis of results utilized effect size measurements (Cohen's d). The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.Results: Out of 1549 initially screened records, 16 published randomized controlled trials encompassing 5300 patients met the inclusion criteria. The interventions involved 18 different PROs measurements, with prominent tools being EORTC QLQ-C30 (utilized in four trials) and PRO-CTCAE (utilized in four trials). Measured endpoints included overall quality of life (12 trials), physical health (11 trials), mental health (7 trials), and social health (5 trials). Overall, the study revealed a limited number of statistically significant findings, with predominantly small to moderate effect sizes associated with the interventions.Conclusions: The findings suggest that the routine integration of PROs into clinical practice does not yield definitive advantages in terms of PROs. It is apparent that further efforts are necessary to ascertain the impact of these interventions on patient health. Systematic review registration: The review protocol was registered on PROSPERO (ID: CRD42022365456).
