BACKGROUND Structured medication interviews improve the medication history in hospitalized patients. In Denmark, a nationwide electronic version of individual pharmacy records (PR) has recently been introduced. Use of these records could improve the medication lists in hospitalized patients. METHODS We prospectively included 500 patients admitted to an acute medical department. In individual patients, the PR was compared with (i) the medication list written in the patient chart and (ii) drug information provided by the patient during a structured drug interview upon admission and during a home visit after discharge. RESULTS Median patient age was 72 years. Upon admission, patients reported using 1958 prescription-only medications (POM) (median four drugs per patient, range 0-14), of which 114 (6%) were not registered in PR. In PR, 1153 POM (median one per patient, range 0-11) were registered during the month preceding admission. The patients did not report 309 (27%) of these upon admission. Home visits were performed in a subgroup of 115 patients. During home visits, 18% of POM registered in PR during the preceding month were not reported. Drug type was predictive of reporting irrespective of patient sex or age. Cardiovascular drugs were reported most and dermatologicals were reported less frequently. Underreporting might be due to recall bias, non-adherence or discontinuation of drugs. CONCLUSIOBS Omission errors are frequent despite structured medication interviews. Pharmacy records or medication lists from all treating doctors must be included in medication reviews in order to reduce recall bias
