Repeat Hospitalizations Predict Mortality in Patients With Heart Failure.

Military Medicine 2017 September
INTRODUCTION: Heart failure (HF) affects more than 5.1 million Americans and is projected to increase. Understanding the relationship between hospitalization and mortality can help to guide clinical management. The aim of the study is to evaluate the impact of repeat HF hospitalizations on all-cause mortality and to determine risk variables related to patient mortality.

MATERIALS AND METHODS: Using administrative data from the Military Health System, a cohort of patients with an index admission for HF between 2007 and 2011 was identified. HF hospitalizations were defined as any hospital claim with an International Classification of Diseases, Ninth Revision diagnosis of 428.xx in the primary diagnosis field over the 7-year study period (2007-2013). Patients were subsequently categorized based on total number of HF hospitalizations. A multivariate Cox regression model, adjusting for age, sex, and comorbidities, was used to estimate hazard ratios. Kaplan-Meier survival curves were constructed based on the frequency of HF hospitalizations.

RESULTS: Of the 51,286 patients admitted for HF, 54.7% were male with a mean (SD) age of 76.3 (10.8) years, and 29,714 died during 135,211 person-years of follow-up. Mean survival time was 2.6, 1.8, 1.5, and 1.3 years after the first, second, third, and fourth hospitalization, respectively. The mortality rate of patients at 30 days and 1 year postindex HF hospitalization was 7.4% and 27.3%, respectively. A history of dementia and chronic kidney disease without dialysis decreased overall survival.

CONCLUSIONS: Repeat HF hospitalizations remain a strong predictor of mortality for existing patients with HF. As a result, clinicians and patients can individualize the optimal treatment strategy and resources on the basis of the suspected prognosis.
