The revolving hospital door: hospital readmissions among patients who are homeless.

BACKGROUND

National attention is increasingly focused on hospital readmissions. Little prior research has examined readmissions among patients who are homeless.

OBJECTIVE

The aim of the study was to determine 30-day hospital readmission rates among patients who are homeless and examine factors associated with hospital readmissions in this population.

METHODS

We conducted a retrospective chart review of patients who were homeless and hospitalized at a single urban hospital from May-August 2012. Homelessness was identified by an electronic medical record flag and confirmed by manual chart review. The primary outcome was all-cause hospital readmission to the study hospital within 30 days of hospital discharge. Patient-level and hospitalization-level factors associated with risk for readmission were examined using generalized estimating equations.

RESULTS

There were 113 unique patients who were homeless and admitted to the hospital a total of 266 times during the study period. The mean age was 49 years, 27.4% of patients were women, and 75.2% had Medicaid. Half (50.8%) of all hospitalizations resulted in a 30-day hospital inpatient readmission and 70.3% resulted in either an inpatient readmission, observation status stay, or emergency department visit within 30 days of hospital discharge. Most readmissions occurred early after hospital discharge (53.9% within 1 week, 74.8% within 2 weeks). Discharge to the streets or shelter versus other living situations was associated with increased risk for readmission in multivariable analyses.

CONCLUSIONS

Patients who were homeless had strikingly high 30-day hospital readmission rates. These findings suggest the urgent need for further research and interventions to improve postdischarge care for patients who are homeless.
