Surgeon Use of Shared Decision-making for Older Adults Considering Major Surgery: A Secondary Analysis of a Randomized Clinical Trial

Because major surgery carries significant risks for older adults with comorbid conditions, shared decision-making is recommended to ensure patients receive care consistent with their goals. However, it is unknown how often shared decision-making is used for these patients. To describe the use of shared decision-making during discussions about major surgery with older adults. This study is a secondary analysis of conversations audio recorded during a randomized clinical trial of a question prompt list. Data were collected from June 1, 2016, to November 31, 2018, from 43 surgeons and 446 patients 60 years or older with at least 1 comorbidity at outpatient surgical clinics at 5 academic centers. Patients received a question prompt list brochure that contained questions they could ask a surgeon. The 5-domain Observing Patient Involvement in Decision-making (OPTION5) score (range, 0-100, with higher scores indicating greater shared decision-making) was used to measure shared decision-making. A total of 378 surgical consultations were analyzed (mean [SD] patient age, 71.9 [7.2] years; 206 [55%] male; 312 [83%] White). The mean (SD) OPTION5 score was 34.7 (20.6) and was not affected by the intervention. The mean (SD) score in the group receiving the question prompt list was 36.7 (21.2); in the control group, the mean (SD) score was 32.9 (19.9) (effect estimate, 3.80; 95% CI, -0.30 to 8.00; P = .07). Individual surgeon use of shared decision-making varied greatly, with a lowest median score of 10 (IQR, 10-20) to a high of 65 (IQR, 55-80). Lower-performing surgeons had little variation in OPTION5 scores, whereas high-performing surgeons had wide variation. Use of shared decision-making increased when surgeons appeared reluctant to operate (effect estimate, 7.40; 95% CI, 2.60-12.20; P = .003). Although longer conversations were associated with slightly higher OPTION5 scores (effect estimate, 0.69; 95% CI, 0.52-0.88; P
