667 Background: Integrating Geriatric Assessment (GA) in the management of older adults with cancer is recommended, yet rarely practiced in routine oncologic care. In this report, we describe the feasibility of integrating the routine incorporation of GA in the management of older adults with GI malignancies and characterize GA impairments. Methods: CARE was adapted from the Cancer and Aging Research Group GA with modifications to create a completely patient-reported version. The CARE assesses self-reported functional status, physical function, nutrition, social support, anxiety/depression, cognitive function, comorbidities, and social activities. Patients ≥ 60yo referred for consultation to the GI Oncology clinic were asked to complete the CARE (paper/pencil) on their first visit. The completed CARE was collected during nurse triage and submitted to the clinical team prior to the physician encounter. Feasibility was defined as completion of the CARE by ≥ 80% of eligible patients during the initial consultation. Results: Between September 2017 and August 2018, 199 eligible new patients attended the GI Oncology Clinic, 192 (96.5%) were approached, and 181 (90.4%) completed the CARE. Most patients (79.6%) felt the length of time to complete was appropriate (median time of 10 minutes [IQR 10-15 minutes]). The mean age was 70y (range 60-96), 54.3% were male, and 75.1% were non-Hispanic white. Common tumor types included colon (27.8%), pancreatic (21.2%), and rectal (10.2%) cancer; predominately advanced stage diseases (stage III: 26.9%; stage IV: 40.0%). GA impairments were prevalent: 48.6% reported dependence in Instrumental Activities of Daily Living, 18.0% reported dependence in Activities of Daily Living, 22.5% reported ≥ 1 fall, 29.4% reported a performance status ≥ 2, 51.3% were limited in walking one block, 75.7% reported polypharmacy (≥ 4 medications), and 84.3% had ≥ 1 comorbidity. Conclusions: Performing a GA in the routine care of older adults with GI malignancies is feasible, and GA impairments are common among older adults with GI malignancies. A fully patient-reported GA such as the CARE may facilitate broader incorporation of GA in the routine clinic work flow.
