National Costs for Cardiovascular-related Hospitalizations and Inpatient Procedures in the United States, 2016-2021

Abstract

The current economic burden of cardiovascular-related hospitalizations grouped by diagnoses and procedures in the U.S. has not been well characterized. The objective was to identify current trends in cardiovascular-related hospitalizations, procedural utilization, and health care costs, using the most recent 6 years of hospitalization data. A retrospective analysis of discharge data from the National Inpatient Sample (NIS) database was conducted to determine trends in cardiovascular-related hospitalizations, costs, and procedures for each year from 2016 to the most recent available dataset, 2021. Total cardiovascular-related costs were adjusted to and reported in 2023 dollars. In 2021, there were 4,687,370 cardiovascular-related hospitalizations at a cost of $108 billion. Heart failure hospitalizations accounted for the highest costs at $18.5 billion, followed by Non-ST-Elevation Myocardial Infarction at $11.2 billion, and stroke at $10.9 billion. Significant upward trends in costs from 2016 to 2021 were observed for heart failure, stroke, atrial fibrillation, ST-elevation myocardial infarction, chest pain, hypertensive emergency, ventricular tachycardia, aortic dissection, sudden cardiac death, pericarditis, supraventricular tachycardia, and pulmonary heart disease. Over the 6 observational years, total costs increased by over $10 billion, representing a 10 percent increase. However, the increases were not linear, as there was a significant increase of 6.5% from 2018 to 2019, then a dip of over 7% from 2019 to 2020, followed by a rise of about 6% from 2020 to 2021. By 2030, total CV-related costs are projected to reach $131.3 billion. For all years, coronary procedures were the most performed, followed by ECMO, non-bypass peripheral vascular surgery, pacemaker placement, and CABG. Both TAVR and MitraClip procedures demonstrated significant upward trends from 2016 to 2021. Overall, from the years 2016 to 2021, cardiovascular-related hospitalizations, costs, and procedures demonstrated upward trends. In conclusion, cardiovascular disease remains a high burden in the hospital setting with tremendous health care costs.
