Interhospital variations in hospital pharmacy markups.

Area of Science:

• Health Services Research
• Health Economics
• Hospital Administration

Background:

• Pharmacy pricing is a key component of hospital revenue generation.
• Understanding the factors influencing pharmacy pricing is crucial for hospital financial management.
• Previous research has not fully explored the link between hospital-wide financial objectives and specific departmental pricing, like pharmacy.

Purpose of the Study:

• To analyze the relationship between pharmacy pricing policies and overall hospital objectives.
• To identify key variables influencing the pharmacy charge-to-cost ratio in South Carolina hospitals.
• To determine if pharmacy pricing aimed for profit maximization or contribution to hospital income.

Main Methods:

• A linear regression model was developed using published hospital data from 64 South Carolina hospitals in 1980.
• The charge-to-cost ratio (pharmacy pricing variable) was regressed against demand (occupancy rate), industry structure (multihospital system affiliation), payer mix (Medicare/Medicaid proportion), nonoperating revenue, and other departmental revenues.
• Data represented predominantly nonprofit hospitals.

Main Results:

• The mean pharmacy markup was 1.99 (+/- 0.49), with significant variation across hospitals.
• The proportion of hospital admissions reimbursed by Medicare and Medicaid (cost-based payers) was the most significant factor influencing pharmacy markup variations.
• Nonoperating revenue and revenue from other departments also significantly correlated with the pharmacy charge-to-cost ratio.
• Occupancy rate and multihospital system affiliation did not show a significant relationship with pharmacy pricing.

Conclusions:

• Hospital pharmacy pricing was significantly influenced by cost-based reimbursement from Medicare and Medicaid, leading to higher charges in areas with a high cost base.
• Hospitals utilized pharmacy revenue to meet overall income targets rather than pursuing maximum profitability through demand-driven pricing.
• These findings highlight the impact of payer mix on departmental pricing strategies within hospitals.
