Background: The Institute of Medicine (IOM) 2013 Report recommends that supportive oncology care start at cancer diagnosis; the Commission on Cancer (CoC) Standard 3.2 requires distress screening and indicated action. The Supportive Oncology Collaborative, collaborative of 100+ clinicians funded by The Coleman Foundation, developed a patient-centric screening tool (CSOC-ST) adapted from ASCO Distress, NCCN Distress Problem List, IOM report and CoC standards, and other validated sub-tools (Weldon, ASCO-Q 2017). The Collaborative then revised the CSOC-ST tool to align with geriatric guidelines. Methods: Literature and guidelines review of geriatric screening, added items to CSOC-ST, and piloted at 4 sites. Descriptive statistics and Fisher’s exact test used. Results: 473 patients screened with added geriatric relevant items to CSOC-ST: self-care concerns (PROMIS Instrumental Support), living alone (ASCO Distress 2014), and memory / cognition (PROMIS item bank). Treatment/care concern items were revised to identify interest in health care power of attorney and advance directives. Geriatric related items endorsed by patients, see Table. PHQ4, Anxiety and Depression, average score 2.4 (mild > 3). Higher scores on the PHQ-4 were significantly associated with each of the following: self-care concerns, memory/cognition concerns and specific treatment/care concerns (p < .0001). Conclusions: Pilot results and comparison to geriatric guidelines identified important items to support geriatric patient reported outcomes screening. After pilot, added 3 items for falls/frailty. Eight sites implementing this CSOC-ST.
