The role of time in patient participation in cancer treatment decision making: A scoping review: Presenter(s): Thomas Wieringa, Leiden University Medical Center, Netherlands

Patients and clinicians often mention time as a barrier for patient participation in cancer treatment decision making. Yet, little is known about how patients, their decision partners, and clinicians perceive the role of time in effective patient participation in cancer treatment decision making, and which strategies can be applied to overcome time-related barriers to patient participation. Our aims are to 1) understand the role of time in patient participation in making decisions about their cancer treatment, and 2) identify strategies to overcome time-related barriers. We carry out a scoping review and conducted a literature search in seven biomedical databases: PubMed, EMBASE.com, Emcare (via Ovid), The Cochrane Library (via Wiley), CINAHL and APA Psycinfo (both via EBSCO) and Web of Science, from their inception until October 5th 2021. Publications are eligible if they report on the role of time in the participation of adult patients (18+) with cancer, and/or on strategies to overcome time-related barriers to patient participation. Reviewers work independently and in pairs to select publications and extract data. We will analyze the data thematically. Our literature search identified 3657 publications. After deduplication, 2064 publications were left for title/abstract screening. We selected 789 publications for full-text screening, which is currently ongoing. Based on our scoping review findings, we aim to develop: 1) a conceptual model of the role of time in the participation of patients in cancer treatment decision making, and 2) an inventory of strategies to overcome time-related barriers to patient participation. Both outcomes will help to understand how and when time can be used most effectively for patients with cancer to participate in treatment decision making.
