Questions: Hospital Economics

Question 1

The DRG (Diagnosis-Related Group) payment system pays hospitals a fixed amount per admission based on the patient's diagnosis, regardless of actual costs incurred. What incentive does this create?

• A. Hospitals are incentivized to provide as many services as possible during each admission
• B. Hospitals are incentivized to minimize costs per admission (shorter stays, fewer tests) because they keep the difference between the DRG payment and actual costs — but may also be incentivized to upcode (classify patients into higher-paying DRGs) or discharge patients prematurely
• C. DRGs eliminate all financial incentives because payment is fixed
• D. Hospitals are incentivized to admit more patients regardless of medical necessity

Answer: (B)

DRG-based payment creates a powerful efficiency incentive: if the hospital can treat a patient for $8,000 when the DRG pays $10,000, it keeps the $2,000 margin. This has dramatically reduced average lengths of stay since DRGs were introduced (Medicare, 1983). The downsides are the incentive to reduce care below the appropriate level (premature discharge, skimping on tests), to upcode patients into higher-paying DRGs, and to avoid admitting patients whose expected costs exceed the DRG payment (cream-skimming). Quality monitoring and coding audits are the regulatory responses.

Question 2

Hospital mergers and consolidation tend to increase prices for privately insured patients. This occurs because consolidated hospital systems have greater bargaining power with insurers.

• T. True
• F. False

Answer: True

Decades of research consistently show that hospital mergers, particularly in already-concentrated markets, increase prices by 20-40% for privately insured patients without corresponding quality improvements. When a hospital is the only option in a region, insurers must include it in their network — patients demand access to the nearby hospital. This gives the hospital leverage to negotiate higher reimbursement rates. The result is higher premiums for the insured population. Antitrust enforcement has been inconsistent in blocking hospital mergers, partly because courts have accepted hospital efficiency claims that the economic evidence does not support.

Question 3

Explain why most US hospitals are organized as nonprofits and whether their behavior differs meaningfully from for-profit hospitals.

Model answer: Nonprofit hospital status reflects the historical origin of hospitals as charitable institutions and the information asymmetry in healthcare — patients cannot easily evaluate care quality, so the nonprofit form signals that the institution is not motivated by profit extraction. Nonprofit hospitals receive tax exemptions in exchange for community benefit (charity care, medical education, research). Empirically, the behavioral differences are smaller than the organizational distinction suggests: nonprofit hospitals pursue revenue, accumulate surpluses, pay executives competitively, and respond to financial incentives similarly to for-profits. The main differences are in payer mix (nonprofits serve more uninsured patients) and the use of surpluses (reinvested rather than distributed to shareholders).

The economic theory explaining nonprofit hospital prevalence is the 'contract failure' theory (Hansmann, 1980): when consumers cannot verify quality, they trust organizations that have no shareholders demanding profit maximization. Whether this trust is empirically justified is debated — studies find modest differences in quality, charity care, and pricing between nonprofit and for-profit hospitals, but the differences are not as large as the tax-exempt status would suggest.
