Introduction:
Hospitalists are increasingly caring for patients with heart failure (HF) at a time when there is need to identify modifiable factors associated with 30-day readmission rates.
Hypothesis:
Patients admitted to General Medicine services (GM) will have higher 30-day readmission rates than those admitted to Cardiology services.
Methods:
This retrospective cohort comprised patients with a principal diagnosis of HF discharged from GM or Cardiology services in 2013-2014 at an urban academic hospital. Patients discharged with hospice were excluded. Index hospitalizations and 30-day readmissions were identified via query of the electronic medical records. Demographics, clinical indices, and hospitalization characteristics were collected by chart review.
Results:
Among 926 patients admitted with HF, 40% were admitted to GM and 60% were admitted to a Cardiology service. Patients on GM were slightly older, more likely female, and more likely to have Medicare (Table). They also had higher LVEF, less RV dysfunction, and less ventricular tachycardia (VT). Rates of non-cardiac comorbidities were comparable between groups. Patients on GM experienced a 1.4-fold increased 30-day readmission rate compared to those on Cardiology services (32% vs. 23%, p=0.023). Multivariate regression analysis showed that admission to GM remained a predictor for 30-day readmission (OR 1.37, [1.01 to 1.87], p=0.048) after controlling for key differences between groups including age, sex, insurance, LVEF, RV dysfunction, VT, and admission blood pressure and hemoglobin.
Conclusions:
HF patients admitted to General Medicine have less structural heart disease, and yet have a higher rate of 30-day readmission compared to those admitted to Cardiology services. This underscores the importance of ensuring that hospitalists obtain adequate heart failure training (related to both inpatient care and optimization of discharge regimens), so as to avoid un-necessary readmissions.
