Pharmacist- versus physician-obtained medication histories.

Area of Science:

• Pharmacology
• Patient Safety
• Health Informatics

Background:

• Accurate medication histories are crucial for safe patient care.
• Physician-obtained medication histories may have limitations.

Purpose of the Study:

• To compare the completeness and accuracy of medication histories obtained by physicians versus pharmacists.
• To evaluate the impact of pharmacist intervention on medication discrepancies.

Main Methods:

• A comparative study involving 55 adult internal medicine patients.
• Two phases: initial pilot testing of a medication history form, followed by pharmacist intervention for discrepancies.
• Data collected on medication identification, doses, and schedules.

Main Results:

• Pharmacists identified significantly more medications (614) than physicians (556).
• Pharmacists documented more doses and schedules.
• 353 discrepancies were found, including 58 unrecorded medications; 142 discrepancies were corrected after physician contact.

Conclusions:

• Pharmacists identify more comprehensive medication information than physicians.
• Pharmacist intervention effectively resolves medication history discrepancies.
• Improving medication reconciliation processes enhances patient safety.
