Abstract
Background: Referral to a skilled nursing facility (SNF) should contribute to reducing hospital readmissions; however, a “revolving door” phenomenon after admission to SNF has been hypothesized to drive readmissions. The urgent need to study the impact of SNF on readmissions in heart failure (HF) was recently emphasized, yet this has never been studied in the community. Objectives: To evaluate the association between discharge to SNF and 30-day readmissions in a community cohort of hospitalized incident HF patients. Methods: Olmsted County, MN residents hospitalized with first ever (incident) HF (International Classification of Diseases-9 th Revision code 428) from 1995 through 2010 were identified. HF was validated by Framingham criteria. Patients residing in a SNF prior to hospitalization were excluded from the analysis. Logistic regression was used to examine the association between discharge to SNF and 30-day readmissions. Results: Among 1360 HF patients (mean age 74±14, 47% male), 241(18%) were referred to a SNF. Overall, 296 (22%) patients were readmitted within 30-days after index hospitalization. The proportion of 30-day readmissions was greater among patients discharged to a SNF compared to patients discharged home (27% vs 21%, p=0.031). After adjustment for age and sex, patients discharged to a SNF had a 40% increase in the odds of having a hospital readmission within 30 days post HF compared to those discharged home (OR: 1.42, 95% CI 1.01-1.99). Further adjustment for year of HF diagnosis, ejection fraction, anemia, renal function, dementia and cancer did not alter the strength of the association (OR: 1.43, 95% CI: 0.99-2.09). Conclusion: Among community patients with HF, 30-day readmissions remain frequent and are more likely to occur among patients discharged to a SNF compared to those discharged home. These data provide new insight into the drivers of HF readmissions and suggest that interventions targeted to HF patients in SNFs may be warranted.
