This study seeks to assess the spiritual needs of older adults with multiple chronic conditions and promote clinician-chaplain collaboration to address the spiritual needs of high-risk vulnerable older adults. We will use a mixed-methods design that includes surveys and semi-structured interviews with approximately 10 patients, 10 clinicians, and 5 chaplains. Quantitative data from validated survey instruments will assess the prevalence and relevance of religiosity and spirituality among participants and their perceived role in healthcare. To complement this, qualitative interviews with patients and clinicians will explore personal experiences, values, and the contextual factors that influence whether and how spirituality is addressed in outpatient care. Interviews will also identify perceived barriers and facilitators to incorporate chaplaincy services into routine care. The study findings will inform efforts to better integrate spiritual support services into outpatient settings, particularly for older adults who may benefit from chaplaincy engagement as part of holistic care. As a Christian Geriatric Physician Scientist and Principal Investigator of the HOlistic Partner Engagement (HOPE) research lab at the University of Massachusetts Chan Medical Center, I am well positioned to carry out this project given my personal and professional background as well as my extensive training on integrating spirituality into healthcare.
