Resolution of drug-related problems in home care patients through a pharmacy referral service.

A referral-based, pharmacist-conducted medication management program designed to identify, categorize, and resolve drug-related problems (DRPs) in a home health care (HHC) population was studied. A clinical pharmacy service model was developed to identify patients at high risk for adverse health events resulting from DRPs. Policies and procedures were developed for this service model, including explicit referral criteria, patient-consent documentation, and physician orders. All identified DRPs were categorized, and pharmacist activities relating to the discovery and resolution of DRPs were tabulated. From July 1, 2001, through March 29, 2002, 80 patients were referred for and received clinical pharmacy services, and pharmacists identified 271 DRPs. Every patient referred had a DRP, and 32% of DRPs were identified by a visit to the patient's home. Nearly 65% of pharmacist recommendations were implemented. Using a referral-based practice model in an HHC setting, pharmacists were able to identify and resolve DRPs for every patient referred.
