  • Abstract

    INTRODUCTION: Heart failure (HF) is the most common discharge diagnosis in the U.S, and patients with HF are at high risk for readmission. Major predictors for readmission include having comorbidities such as diabetes, chronic lung disease, among many others. In addition to comorbidities, readmission rates also defer by sex, age, SES, and primary payer. The 30-day and 90-day readmission rates for HF by primary payer type have been extensively published. However, there is a lack of knowledge in the medical literature regarding the readmission rate 3 months post-index admission. In our study, we retrospectively follow subjects for 1 year and report on differences in readmission free period by primary payer.

    METHODS: We used the 2017 National Readmission Database (NRD) to address our research question. NRD contains nationally representative and comprehensive patient-level, hospital-level, and district-level data.

    RESULTS: Relative to those on private insurance, those on Medicare and Medicaid had a 5% (p < 0.001) and a 6% (p < 0.001) increase in the hazard of readmission, respectively after adjusting for known covariates such as age, sex, comorbidity, weekend admission, elective admission, hospital bed size, and teaching status of the hospital. 

    CONCLUSION: Medicare and Medicaid beneficiaries have an increased hazard of readmission for HF relative to those on private insurance. More research needs to be done to understand the disparity in the readmission-free period by primary payer.
