Factors Influencing the Dispensing of One-Dose Package Medications to Elderly Outpatients / 社会薬学

ABSTRACT

<p>Decreased adherence to medications among the elderly has become a problem in recent years. To overcome this problem, the dispensing of one-dose packages of medicines has been suggested. The purpose of this study was to survey elderly outpatients in a regional hospital at the Tokachi Development and Promotion Bureau and to analyze the factors that influence patients’ preference for a one-dose package medicine. The dispensation of one-dose package medication was observed in 20% of elderly outpatients. A correlation between the percentage of dispensed one-dose package medications and the number of agents was observed. Furthermore, dispensing rates of one-dose package medications increased with aging. Within the various departments analyzed, one-dose packaging rate was high in the Departments of Cardiology and Psychiatry. In this study, the correlation between residential municipalities of outpatients and one-dose package medications was examined. In the municipalities with a high rate of aged individuals and high average of household members, one-dose package medication rate was low. Multivariate logistic regression analysis confirmed these factors as significant. That one-dose packaging rates increased with the number of drugs and aging are consistent with the notion that one-dose package medications are designed to increase drug adherence among the elderly. Interestingly, one-dose package dispensing rate was low in areas with advanced aging. Because aging in Japan is expected to advance in the future, it is important to survey one-dose package dispensations.</p>
