Abstract

Objectives To assess potential avoidable hospitalizations of nursing home (NH) residents as a function of the percentage of clinical effort their primary care provider (PCP) devotes to NH practice. Design Retrospective cohort study. Setting NHs in Texas. Participants Residents newly admitted to long-term NHs in 2006 to 2008 were identified by linking the Minimum Data Set to 100% Texas Medicare claims data (N = 12,249). Measurements The care that residents received over successive 6-month periods was measured as a time-dependent covariate. Potentially avoidable hospitalizations and Medicare costs were assessed over 6 to 48 months. Results Seventy percent of NH residents had a physician as their major PCP, 25% had an advance practice nurse (APN), and 5% had a physician assistant (PA). Physician PCPs who derived less than 20% of their Medicare billings from NH residents cared for 36% of all NH residents. Most NH residents with APN or PA PCPs had providers with 85% or more of Medicare billings generated in NHs. Residents with PCPs who devoted less than 5% of their clinical effort to NH care were at 52% higher risk of potentially avoidable hospitalization than those whose PCPs devoted 85% or more of their clinical effort to NHs (hazard ratio = 1.52, 95% confidence interval = 1.25-1.83) and had $2,179 higher annual Medicare spending, controlling for PCP discipline. Conclusion The percentage of clinical effort that providers devote to NHs is associated with risk of avoidable hospitalization.
