Hospital Utilization for Coronary Artery Disease, 1997-2014

Area of Science:

• Cardiovascular Medicine
• Health Services Research
• Public Health Policy

Background:

• Coronary artery disease (CAD) is a major cause of illness, death, and healthcare expenses in the U.S.
• Limited research exists on the impact of public health and payment reforms on inpatient care for CAD patients.
• Understanding trends in hospital utilization is crucial for managing CAD's burden.

Purpose of the Study:

• To analyze trends in hospital discharges, charges, and discharge destinations for patients with CAD.
• To examine these trends over a significant period (1997-2014) using national data.
• To identify demographic and geographic factors influencing inpatient care patterns for CAD.

Main Methods:

• Longitudinal study design.
• Descriptive analysis of the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) data.
• Analysis of over 1.3 million patient discharges.

Main Results:

• A total of 1,333,996 discharges were analyzed.
• Patients aged 65-84 were highest users, followed by the 45-64 age group.
• The death rate rose from 5961 to 7217 per 10,000 patients.
• Mean hospital charges increased over fivefold, from $9,100 to $49,643.
• Urban hospital charges ($51,666) were substantially higher than rural ($25,548) in 2014.
• Patients with private insurance had higher mean charges than those with Medicaid/Medicare.
• Discharges to home and associated healthcare costs increased by 4.1% and 4.8%, respectively.

Conclusions:

• Future research should utilize comprehensive datasets like Medicare claims to understand patient-level factors in CAD inpatient care.
• Enhanced cardiac rehabilitation and patient education are vital in post-hospital settings for CAD patients.
• Addressing disparities in care based on location and insurance type is necessary.
