Effect of initiation, termination, and reinitiation of consultant clinical pharmacist services in a geriatric long-term care facility.

Abstract

The effect of initiation, termination, and reinitiation of consultant clinical pharmacist services of drug regimen review and physician communication on patient drug use in a 72-bed geriatric long-term care facility was assessed at five points in time: initiation, termination, reinitiation, then 3 months and 3 years after reinitiation of services. Both times when the consultant was retained, drug use was cut almost in half (46.1% and 42.7%, respectively), with essentially the same number of established diagnoses per patient at each point in time. Conversely, before the consultant services were initiated, and when the consultants services were terminated, drug use was twice as great as when consultant pharmacist was retained. Regularly scheduled drugs increased 59%, and pro re nata (prn) drug increased 200% during the period between the termination and reinitiation of consultant services. There was also a lower admission, discharge, and death rate as well as higher hospitalization rate when the consultant was retained. It appears that the consultant clinical pharmacist has an impact on drug cost in long-term care facilities that is reversed when drug regimen review is removed and renewed when services are reinitiated.
