Could payer mix affect length of stay or readmissions among an outpatient palliative care cohort

165Background: Outpatient palliative care clinics (PCC) are a developing frontier of palliative medicine. Characterizing and promoting financially viable models for payment of services are imperative to the sustainability of PCC. There is a paucity of research addressing payer mix – meaning the breakdown of individuals and organizations that pay for a provider's services – in PCC or its impact on metrics important to quality in PC such as hospital length of stay (LOS) and hospital readmissions. We seek to describe the payer mix for our academic outpatient PC practice. Furthermore, we sought to identify if payer mix (commercial, government—Medicare, Medicaid – or self-pay) influenced hospital LOS, discharge to hospice, or readmissions. Methods: After obtaining IRB approval, we conducted a retrospective chart review of supportive oncology patients from 2014-2017 (n = 3137) using data restricted to ICD10 codes for solid tumors. We performed bivariate tests and multivariable logistic regressions to examine th...
