Abstract
AIM: The present study aimed to evaluate drug costs per resident at Japanese intermediate care facilities for older adults (called Roken) in relation to drug utilization after admission to these facilities. The payment, including coverage of drugs, is mainly determined by the resident's long-term care needs. METHODS: A nationwide drug utilization survey was carried out. The participants were 1324 residents of 350 Roken (up to five individuals per facility) who were admitted in 2015 and agreed to participate in this study. Drug costs per resident per month at admission and 2 months later were calculated for drugs prescribed for regular use. Associations between characteristics of the residents and drug costs were examined. RESULTS: A wide variation in drug costs with a long right tail was observed. Median drug costs were $77 (interquartile range $34-147) at admission, and $46 (interquartile range $19-98) in month 2. There was no apparent association between the level of long-term care needs and drug costs, adjusting for sex, age and main place of residence before admission. Anti-dementia drugs accounted for the largest portion of total drug costs at admission (15.4%) and in month 2 (12.4%). The average drug cost per user was also the highest for anti-dementia drugs ($90.2 per user per month), followed by drugs for Parkinson's disease ($70.3). The proportion of generic drugs across all drug classes examined increased after admission. CONCLUSIONS: These findings might suggest that implementation of the bundled payment scheme would be effective for the reduction of medication costs in institutional long-term care.
