Assessment of Price Variation in Coronary Artery Bypass Surgery at US Hospitals

Area of Science:

• Health Economics
• Healthcare Management
• Medical Informatics

Background:

• Little is known about hospital pricing for coronary artery bypass grafting (CABG).
• New price transparency data provides an opportunity to assess CABG price variation.
• Understanding pricing is crucial for healthcare spending and patient access.

Purpose of the Study:

• To assess variation in CABG prices across US hospitals.
• To examine the association between higher prices and hospital characteristics.
• To investigate the relationship between CABG prices and quality of care.

Main Methods:

• Utilized Turquoise database for diagnosis related group code 236 prices.
• Linked price data with Medicare Facility ID to hospital characteristics.
• Performed univariate and multivariable analyses to identify price predictors.

Main Results:

• Median commercial and self-pay rates were 2.01 and 2.64 times the Medicare rate.
• Significant price variation existed across hospitals and within hospitals.
• Major teaching and investor-owned hospitals had significantly higher prices.
• CABG prices were not associated with quality metrics like mortality or patient ratings.

Conclusions:

• Significant variation in CABG pricing exists, influenced by hospital characteristics.
• Major teaching status and investor ownership are associated with higher CABG prices.
• Higher prices do not correlate with improved quality of care, indicating a need for further research.
