A randomized controlled trial of a patient navigator intervention to reduce hospital readmissions in a safety net health care system
Poor care coordination at hospital discharge can result in avoidable readmissions. The study aims to evaluate the effect of a CHW intervention, the Patient Navigator (PN), on readmission rates and post-discharge health care use in a safety-net population.
Design: Randomized-controlled trial comparing usual care to a model in which a PN provides supportive post-discharge services. An academic safety-net medical center and affiliated primary care practices.
Methods: Eligible patients were randomly assigned to the PN intervention or usual care. In the PN intervention, a bilingual hospital-based CHW engaged in discharge planning and conducted outreach calls for 30 days after initial discharge. PNs assisted patients with follow-up appointments, obtaining and taking medications, transportation, financial barriers, and linkages to community resources. Socio-demographic, clinical, and utilization data were obtained from electronic medical records.
Results: Total enrolled: 423 PN patients and 513 controls. Readmissions per patient were lower in the PN group compared to controls (0.70 vs. 0.81), as were total hospital days (3.42 vs. 3.59). In addition, more PN patients had a primary care visit within 30 days (77.1% vs. 68.6%).
Conclusion: Preliminary results show a trend toward a reduction in probability of 30-day readmission, number of readmissions, and total hospital days for PN-intervention patients, and a trend toward greater probability of a primary care visit within 30 days of discharge.
