Drug use and perceived health in recently hospitalized older people.

Older patients often have multiple diseases, resulting in treatment with many drugs. This may increase the risk for drug-related problems. This study aimed to analyse the congruence between the patient's self-reported drug use and the medical record, and the relationship to perceived health among older patients recently discharged from hospital. A total of 200 patients over 65 years of age who were admitted to a medical ward and were treated with at least one drug participated in an interview study one week after discharge from the hospital. The patients provided information on their current drug therapy. This information was compared to the prescriptions documented in the medical record. Thirty per cent of the study population reported a drug use which was in congruence with the medical record, 28% used less drugs than prescribed, and 42% more. Statistical analysis showed a high probability of non-congruence with prescriptions among patients who reported poor health.
