Summary
Most hospitals rely on pharmacist knowledge for drug interaction detection, but satisfaction remains low. Computerized systems and audits improve satisfaction with drug interaction management.
Area of Science:
- Pharmacy Practice
- Health Services Research
- Pharmacovigilance
Background:
- Drug interactions pose a significant risk in healthcare settings.
- Effective management of drug interactions is crucial for patient safety.
- Understanding current pharmacy department methods and satisfaction levels is essential.
Purpose of the Study:
- To evaluate methods used by hospital pharmacy departments for managing drug interactions.
- To assess the satisfaction levels of pharmacy directors with existing drug interaction management strategies.
- To identify factors influencing satisfaction with drug interaction detection and follow-up processes.
Main Methods:
- A survey was conducted in January 1991 targeting directors of pharmacy departments in 300 large hospitals (>200 beds).
- A questionnaire was mailed, with 167 (56%) completed responses received.
- Data collected included pharmacy service location, drug interaction detection methods, resource availability, and satisfaction with computerized systems.
Main Results:
- 83% of hospitals detected drug interactions primarily through pharmacist knowledge.
- Central pharmacies were more likely to have comprehensive drug interaction resources (AHFS Drug Information, Facts and Comparisons) than decentralized pharmacies.
- 54% of institutions had computerized drug distribution systems with interaction components; 56% found them indispensable or helpful, while 44% found them partially effective.
- 68% believed computer programs increased interaction identification, and 68% perceived proper pharmacist follow-up.
- Overall, 66% were unsatisfied with their drug interaction management methods.
Conclusions:
- A significant majority of hospitals were unsatisfied with their current drug interaction management methods.
- Satisfaction with drug interaction management was higher in institutions with computerized drug interaction programs and those reporting departmental audits or quality assessment procedures.
- The findings suggest a need for improved systems and processes for drug interaction detection and follow-up in hospital pharmacy practice.
