[Factors influencing noncompliance with medication regimens in the elderly].
Poor medication compliance is a major issue in the health care of older patients. To identify risk factors for medication noncompliance in the elderly, inpatients aged 65 years and older at Nagoya University Hospital and at Chubu National Hospital underwent a comprehensive geriatric assessment and tests for the assessment of medication compliance. The dependency of medication assistance by a caregiver is associated with low physical function activity, cognitive impairment, depression and communication inability. Medication noncompliance was not associated with the score of any component of comprehensive geriatric assessment. There was a good relationship between patient's knowledge of medications and the frequency of dosage interval, both of which were associated with the score of instrumental ADL, cognitive function and communication ability. The knowledge was also associated with the medication compliance at Nagoya University Hospital but not at Chubu National Hospital. These results may suggest that the elderly patient's understanding of a medication regimen is important but that other factors are also required to maintain their treatment regimen.
