ABSTRACT Current models of care delivery are failing patients with complexity, like those living with HIV, mental illness and other psychosocial challenges. These patients often require resource-intensive personalized care across hospital and community settings, but available supports can be fragmented and challenging to access and navigate. To improve this, the authors created a program to enhance integrated, trauma-informed care through an innovative educational role for a HIV community caseworker embedded in an academic HIV Psychiatry clinic, called the Mental Health Clinical Fellowship. Through qualitative interviews with 21 participants (patients, physicians, clinicians and Mental Health Clinical Fellows) from October 2020–March 2023, the authors explore how implementation of this program affects patient experiences and satisfaction with care. Patients described their care experiences as less stigmatizing, more accessible, holistic and coordinated. They often attributed this to the integration between fellow and psychiatrist, and specifically the accessible stance of community organizations embedded within a hospital, which helped build trust. Interchangeable and integrated support by caseworker and psychiatrist improved patient engagement in psychiatric management and patient satisfaction with their care. Cross-context and cross-disciplinary care provision that includes providers from community and hospital working directly together to deliver care can improve care for patients with significant complexity.
