Drug use in a trauma intensive-care unit

Area of Science:

• Pharmacology
• Critical Care Medicine
• Health Economics

Background:

• Medication prescribing patterns and associated costs in trauma intensive-care units (TICUs) are critical for resource management.
• Understanding drug utilization is essential for optimizing patient care and controlling healthcare expenditures.

Purpose of the Study:

• To analyze medication prescribing patterns and estimate the costs of specific drug therapies in a TICU.
• To identify correlations between patient demographics, injury severity, and drug utilization.
• To provide data for future cost containment and drug use evaluation initiatives.

Main Methods:

• Retrospective analysis of demographic data and total drug use (scheduled, p.r.n., single-dose) for 278 TICU patients.
• Categorization of medications into major drug classes and cost estimation for scheduled therapies.
• Statistical analysis including simple linear regression and one-way ANOVA to identify correlations and differences in drug use.

Main Results:

• Patients received an average of 9.1 +/- 6.5 medications, with scheduled drugs accounting for 58% of total use.
• Age, injury severity score, trauma score, and length of stay correlated with drug use.
• Antimicrobial, stress ulcer prophylaxis, and bronchodilator therapies represented over 66% of scheduled drug costs, exceeding $47,000.
• Analgesics, antipyretics, sedatives, and muscle relaxants comprised nearly 75% of p.r.n. orders.

Conclusions:

• Drug use in the TICU is extensive, with specific categories driving significant utilization and cost.
• Identifying high-use drug categories can guide future cost-containment strategies and drug use evaluations.
• This study provides valuable insights into TICU pharmacotherapy for improving resource allocation and patient management.
