Little is known about the impact of early palliative care (EPC) combined with motivational interviewing (MI) for persons living with AIDS (PWA). We compared the cost and quality-adjusted life-years (QALYs) of EPC + MI (n = 61) versus usual care (UC) (n = 60) for patients with AIDS, not on antiretroviral medications, enrolled into the Living Well Project trial. Data on clinic, emergency department, and hospital visits were collected through self-report and billing records. Risk-adjusted average annual health care costs were estimated using a generalized linear model with a gamma log-link function. QALYs were calculated using the SF-12v2. Cost-effectiveness was defined as cost per QALY gained. Estimated intervention costs were $165 per participant. EPC + MI reduced costs by 33% (AOR = 0.67; CI 95%: 0.15, 0.93). QALYs did not differ between groups. Results suggest EPC + MI for PWA is cost-saving and maintains quality of life compared to UC due to reduced hospital and ED costs.
