Use of a Medicaid database to analyze pharmaceutical services in long-term-care facilities

A profile of Wisconsin pharmacies that provide services to Medicaid recipients in long-term-care facilities (LTCFs) was developed, and the relationships among pharmacy characteristics and drug use and reimbursement for pharmaceutical services in these pharmacies were studied. Computer-generated reports of Medicaid claims of all pharmacies that had received $1000 or more for services provided to LTCFs from July through September 1984 were included in the study; these claims were submitted by 255 pharmacies on behalf of 32,410 recipients. The reports contained the following individual pharmacy data: geographic location, total dollar payments, total number of Medicaid recipients served, percentage of recipients residing in LTCFs, total number of payments from Medicaid for prescriptions, amount paid to the pharmacy for LTCF recipients as a percentage of total payments, percentage of prescriptions paid at the unit dose rate, and average number of prescriptions and cost per LTCF recipient. An average of $137.30 per recipient was reimbursed, representing an average of 12.3 prescriptions per recipient. The average number of prescriptions per recipient did not vary among pharmacies on the basis of unit dose or traditional distribution system, vendor-consultant status of the pharmacist, location of the pharmacy, or the proportion of LTCF claims to total Medicaid prescription claims. The average amount paid per recipient was related to the average number of prescriptions per recipient, the use of a unit dose system, and the proportion of nursing home claims to total claims submitted. A Medicaid database can be useful for characterizing pharmaceutical services and drug use in LTCFs.
