Disparities in length of goals of care conversations between oncologists and patients with advanced cancer.

19 Background: Studies show minority patients have inadequate discussions about treatment, prognosis, and goals of care (GoC) which translate into substandard treatment, worse quality of life, and poorer survival than whites. However, there is a paucity of data on the quality of communication among minority patients with advanced cancer. We studied factors impacting the oncologists’ time spent during GoC discussion visits with their minority and non-minority patients. Methods: At community, academic, municipal, and rural hospitals, we recruited and randomized solid tumor oncologists and their newly diagnosed advanced cancer patients with <2-year prognosis to participate in a RCT, testing a coaching model of communication skills training. Patients were surveyed after post-imaging visits. These visits were audiotaped and median encounter time recorded. We define GoC discussions as patients report that their doctor talked about preferences for cancer treatment and clarified things most important to them given their illness. Comparisons were made using non-parametric tests. We used mix-effect models for risk adjustment. Results: For 22 randomized oncologists in the study,142 post-imaging encounters were audiotaped. Of these, 38% were non-Hispanic White, 32% non-Hispanic Black and 19% Hispanic. The median face to face time oncologists spent during a GoC encounter with an advanced cancer minority patient was 12 minutes compared to 17 minutes for non-minorities (p=0.002). Median encounter times varied between the four sites, ranging from 10 minutes to 18 minutes, p=0.009. For visits that took place after progression of disease, duration of visit was 18 minutes versus 13 minutes if there were no progression, p=0.007. After controlling for clustering of the patients within the hospitals and progression of disease, time spent with minority patients remained less than with non-minority patients (15 min vs. 18 min, p=0.02). Conclusions: Oncologists' time spent conducting GoC conversations with minority cancer patients is significantly less than with non-minority patients. Evaluating factors that contribute to this disparity is critically important to ensure minority patients receive high-quality cancer care. Clinical trial information: NCT02374255.
