Exploration of shared decision making in oncology within the United States: a scoping review.

ABSTRACT

PURPOSE: Shared decision making (SDM) among the oncology population is highly important due to complex screening and treatment decisions. SDM among patients with cancer, caregivers, and clinicians has gained more attention and importance, yet few articles have systematically examined SDM, specifically in the adult oncology population. This review aims to explore SDM within the oncology literature and help identify major gaps and concerns, with the goal to provide guidance in the development of clear SDM definitions and interventions. METHODS: We conducted a scoping review using the Arksey and O'Malley approach along with the PRISMA Extension for Scoping Reviews Checklist. A systematic search was conducted in four databases that included publications since 2016. RESULTS: Of the 364 initial articles, eleven publications met the inclusion criteria. We included articles that were original research, cancer related, and focused on shared decision making. Most studies were limited in defining SDM and operationalizing a model of SDM. There were several concerns revealed related to SDM (1) racial inequality, (2) quality and preference of the patient, caregiver, and clinician communication is important, and (3) the use of a decision-making aid or tool provides value to the patient experience. CONCLUSION: Inconsistencies regarding the meaning and operationalization of SDM and inequality of the SDM process among patients from different racial/ethnic backgrounds impact the health and quality of care patients receive. Future studies should clearly and consistently define the meaning of SDM and develop decision aids that incorporate bidirectional, interactive communication between patients, caregivers, and clinicians that account for the diversity of racial, ethnic, and sociocultural backgrounds and preferences.
