An evaluation of a medication history method

Area of Science:

• Pharmacology
• Clinical Pharmacy
• Health Informatics

Background:

• Accurate drug histories are crucial for patient safety and effective treatment.
• Traditional methods of documenting patient medications can be incomplete.
• Identifying all patient-reported and prescribed drugs is a significant clinical challenge.

Purpose of the Study:

• To evaluate a novel drug history method utilizing a review of systems (ROS) format.
• To compare the efficacy of the ROS method against standard medical record documentation for drug history collection.
• To assess the time efficiency of the experimental drug history method.

Main Methods:

• The study employed a review of systems (ROS) history format, linking common symptoms/diseases to corresponding drug treatments.
• Data were collected over eight weeks from general medicine and ICU inpatients.
• Drug histories obtained via the ROS method were compared to those documented in medical records, with statistical analysis using chi-square.

Main Results:

• The ROS method identified 406 drugs, significantly more than the 60 drugs documented in medical records (p < 0.001).
• The experimental method proved productive, with a comparable performance time of 14 +/- 5.85 minutes.
• A higher number of legend, nonlegend, and unidentifiable drugs were uncovered using the ROS approach.

Conclusions:

• The review of systems (ROS) drug history method is a highly productive technique for comprehensive medication identification.
• This concise and logically organized method significantly enhances the completeness of drug histories compared to standard documentation.
• The ROS approach offers a valuable tool for improving medication reconciliation and patient safety in clinical settings.
