Potential drug interactions in surgical patients
American Journal of Hospital Pharmacy
|July 1, 1985
Summary
Hospitalized surgical patients frequently experience drug interactions, with 17% having at least one potential issue. Digoxin and cimetidine were the most common interacting drugs, highlighting the need for careful medication monitoring.
Area of Science:
- Pharmacology
- Clinical Pharmacy
- Patient Safety
Background:
- Drug interactions pose a significant risk in hospitalized patients.
- Surgical patients often receive multiple medications, increasing interaction potential.
- Identifying and mitigating drug interactions is crucial for patient safety.
Purpose of the Study:
- To evaluate the incidence and frequency of potentially serious drug interactions.
- To identify common interacting drug pairs in hospitalized surgical patients.
- To assess the need for enhanced medication monitoring in this population.
Main Methods:
- Retrospective review of 1825 patient profiles from a tertiary-care teaching hospital.
- Analysis of drug profiles over two six-month periods.
- Focus on well-documented, potentially harmful drug interactions.
Main Results:
- At least one potential drug interaction was identified in 17% of patients.
- Drug interactions occurred at a rate of 1 per 59 patient days.
- Digoxin and cimetidine accounted for nearly 90% of identified interactions.
Conclusions:
- Hospitalized surgical patients are at high risk for drug interactions.
- Close medication monitoring is essential for this patient group.
- Targeted interventions for digoxin and cimetidine interactions may be beneficial.
