Abstract: OBJECTIVES: Polypharmacy (PP) and potentially inappropriate medications (PIM) are common in older adults with cancer, increasing the risk of adverse outcomes. Approaches to identifying and addressing PP/PIM are needed. MATERIALS AND METHODS: Patients ≥70 years with advanced cancer were enrolled in this cluster-randomized study. All underwent geriatric assessment (GA), and oncologists randomized to the intervention arm received GA-driven recommendations; no information was provided to oncologists at usual care sites. For patients with PP (≥5 medications or ≥1 high-risk medication), clinic visits with treating oncologists were audiorecorded and transcribed, and discussions regarding PP/PIM identified. Quality of provider response was coded as dismissed, mentioned, acknowledged, or addressed. RESULTS: Forty patient transcripts were analyzed (20 per arm). More discussions occurred in the intervention group (n = 81) versus the usual care group (n = 51). More concerns per patient were brought up in the intervention group (4.1 vs. 2.6, p = 0.07). Physician-initiated discussions were higher in the intervention group (73% vs. 49%, p = 0.006). More PP concerns were "addressed" in the intervention group (59% vs. 45%, p = 0.1). Oncology supportive care medication concerns were more often addressed in the usual care group (58% vs. 18%, p = 0.008), but medication management concerns were addressed more commonly in the intervention group (38% vs. 79%, p = 0.003). CONCLUSION: In this secondary analysis, a GA-driven intervention increased PP discussions, particularly about total number of medications and medication management. PP/PIM concerns were more commonly addressed in the intervention group, except for the subset of conversations about supportive care medications.
