Abstract
INTRODUCTION: Venous thromboembolism (VTE) is a leading cause of preventable morbidity and mortality among hospitalized patients in the US. The objectives of this study were to examine VTE prophylaxis patterns and risk for VTE events during hospitalization and post-discharge among patients hospitalized for acute illnesses in the US.
METHODS: Acutely ill hospitalized patients were identified from the MarketScan databases (January 1, 2012-June 30, 2015). Proportions of patients that received inpatient and/or outpatient VTE prophylaxis were determined. VTE rates were calculated for the overall study population and for each subpopulation with each acute illness type. Risk for VTE events after the index admission was determined by Kaplan-Meier analysis.
RESULTS: Of the acutely ill patients (n = 17,895, mean age: 58.4 years), most were hospitalized for infectious diseases (40.6%), followed by respiratory diseases (31.0%), cancer (10.7%), heart failure (10.4%), ischemic stroke (6.4%), and rheumatic diseases (0.9%). Among the entire study population, 59.1% did not receive any VTE prophylaxis, and only 7.1% received both inpatient and outpatient prophylaxis. Among the overall study population, cumulative VTE rate, including during index admission and within 6 months post-discharge, was 4.6%. VTE risk in the inpatient and outpatient continuum of care remained elevated up to 30-40 days after hospital admission, with 60.1% of VTEs occurring within 40 days of hospital admission.
CONCLUSION: In this retrospective analysis of nearly 18,000 patients hospitalized for acute illnesses, 59.1% did not receive any VTE prophylaxis and only 7.1% received VTE prophylaxis in both the inpatient and outpatient continuum of care, despite significant VTE risk extending from hospitalization into the post-discharge period.
