title: Can palliative home care reduce 30-day readmissions? Results of a propensity score matched cohort study.
abstract: OBJECTIVE
  This study examined the impact of palliative home nursing care on rates of hospital 30-day readmissions.
  
  
  METHODS
  The electronic health record based retrospective cohort study was performed within home care and palliative home care programs. Participants were home care patients discharged from one of three urban teaching hospitals. Outcome measures were propensity score matched rates of hospital readmissions within 30 days of hospital discharge.
  
  
  RESULTS
  Of 406 palliative home care patients, matches were identified for 392 (96%). Of 15,709 home care patients, 890 were used at least once as a match for palliative care patients, for a total final sample of 1282. Using the matched sample we calculated the average treatment effect for treated patients. In this sample, palliative care patients had a 30-day readmission probability of 9.1% compared to a probability of 17.4% in the home care group (mean ATT: 8.3%; 95% confidence interval [CI] 8.0%-8.6%). This effect persisted after adjustment for visit frequency.
  
  
  CONCLUSIONS
  Palliative home care may offer benefits to health systems by allowing patients to remain at home and thereby avoiding 30-day rehospitalizations.
