A Geriatric Oncology Collaborative Care Intervention for Older Adults With Advanced Cancer

Cancer disproportionately affects older adults, and the number of older adults with cancer is expected to grow as the population ages. Older adults with advanced cancer often possess a distinct set of medical and psycho-social issues that makes caring for the geriatric oncology population challenging for oncologists. Currently, a critical knowledge gap exists regarding how best to deliver comprehensive cancer care targeting the unique geriatric and palliative care needs of these individuals. The investigators propose to develop a geriatric oncology collaborative care intervention to improve supportive care outcomes for older adults with advanced gastrointestinal (GI) and genitourinary (GU) cancer. GI and GU cancers are among the leading causes of cancer death in the geriatric cancer population, and patients with advanced GI and GU cancers experience a high symptom burden. The intervention will entail visits with an oncology advanced practice nurse trained to address patients' unique needs, who will meet regularly with a supervising team of geriatric, palliative care, social work, and pharmacy clinicians for feedback and iterative reevaluation of the care plan. Using nurses who are already integrated into the oncology setting represents a scalable model that addresses the workforce shortage of geriatric and palliative care clinicians. The investigators used conceptual models for collaborative care and geriatric interventions to develop an initial intervention framework, and prior research to develop a preliminary intervention manual. In Aim 1, the investigators will refine and finalize both the intervention and the intervention manual based on qualitative data from patients, caregivers, and clinicians to ensure the intervention targets the unique needs of older adults with advanced cancer. In Aim 2, the investigators will modify the intervention and study methods with an open pilot study (n=10). In Aim 3, the investigators will conduct a pilot randomized trial (n=75) to assess the feasibility and preliminary efficacy of the geriatric oncology collaborative care intervention for improving patients' QOL, symptom burden, and functional outcomes.
