NURSING-HOME RESOURCES AND TRANQUILIZER USE AMONG THE INSTITUTIONALIZED ELDERLY

Objective. To examine the relationship between selected resident and facility characteristics and the frequency and quality of tranquilizer prescribing and use in skilled nursing facilities. Design. Retrospective review of medication profiles and pharmacy billing records using standardized protocol. Settings. Seven skilled nursing facilities. Participants. All residents aged 65 years or older were eligible. Consent was given by 760 residents or guardians. Six refused permission. Outcome Measures. Drug use measures included the presence or absence of a tranquilizer order, any tranquilizer use during previous 30 days, and any deviation from selected drug use criteria. Results. Of 760 residents, 38% had an order for an antipsychotic or antianxiety agent, and 28% actually received a tranquilizer. Comparing tranquilizer practices with specific drug-use criteria showed that nearly 19% of all elderly residents were exposed to some type of excess use such as long duration, polymedicine, or therapeutic duplication. Residents in facilities with less adequate staffing and other resources were significantly more likely to have a tranquilizer order, to have a tranquilizer administered, and to have any deviation from drug-use criteria. The data also show higher rates of deviation from criteria among residents with a diagnosed mental disorder, younger residents, and Medicaid recipients. Conclusion. More attention must be paid to environmental factors that may undermine current efforts to improve psychotropic drug prescribing and use in skilled nursing facilities.
