Hospital Teaching Status and Medicare Expenditures for Complex Surgery

Area of Science:

• Healthcare economics
• Surgical outcomes research
• Hospital administration

Background:

• Emerging payment policies target low-value healthcare, potentially disadvantaging teaching hospitals.
• Perception exists that teaching hospitals are less efficient, impacting their financial standing.
• Understanding cost and outcome differences is crucial for fair healthcare policy.

Purpose of the Study:

• To evaluate the relationship between hospital teaching intensity, Medicare payments, and perioperative outcomes.
• To determine if teaching hospitals incur higher costs for complex procedures.
• To assess if teaching status influences patient outcomes after surgery.

Main Methods:

• Analysis of Medicare Provider and Analysis Review (MPAR) files for patients aged 65-100 undergoing AAA repair, pulmonary resection, or colectomy (2009-2012).
• Hospitals categorized by teaching intensity (quintiles based on resident-to-bed ratio).
• Risk-adjusted 30-day Medicare payments and perioperative outcomes assessed after price standardization for graduate medical education, DSH, and wage index.

Main Results:

• Initially, very major teaching hospitals showed higher unadjusted Medicare payments for all three procedures compared to nonteaching hospitals.
• After price standardization, Medicare payments were not statistically different between very major teaching and nonteaching hospitals for AAA repair and pulmonary resection.
• An attenuated but significant payment difference persisted for colectomy; teaching hospitals had higher complication/readmission rates but lower failure-to-rescue and mortality rates.

Conclusions:

• Price-standardized Medicare payments for complex surgical episodes are similar between teaching and nonteaching hospitals.
• Teaching intensity does not inherently lead to higher Medicare spending for these procedures after accounting for payment adjustments.
• Teaching hospitals may offer a different risk-benefit profile, with higher complications but better survival rates.
