Abstract
OBJECTIVE: Patient involvement in treatment decisions is recommended in clinician-patient encounters. Little is known about how oncologists engage patients in shared decision making in non-Western countries. We assessed the prevalence of shared decision making among Singaporean oncologists and analysed how they discussed prognosis. METHODS: We audio-recorded 100 consultations between advanced cancer patients and their oncologists. We developed a coding system to assess oncologist encouragement of patient participation in decision making and disclosure of an explicit prognosis. We assessed patient and oncologist characteristics that predicted these behaviours. RESULTS: Forty-one consultations involved treatment discussions. Oncologists almost always listed more than one treatment option (90%). They also checked patient understanding (34%), discussed pros and cons (34%) and addressed uncertainty (29%). Oncologists discussed prognosis mostly qualitatively (34%) rather than explicitly (17%). They were more likely to give an explicit prognosis when patients/caregivers asked questions related to prognosis. CONCLUSION: Oncologists in our sample engaged their patients in decision making. They have areas in which they can improve to involve patients at a deeper level to ensure shared decision making. Findings will be used to develop an intervention targeting oncologists and patients to promote patient involvement in decision making.
