Collaborative medication management services: improving patient care.

OBJECTIVE To implement and evaluate a collaborative medication management service model. DESIGN Participatory action research. SETTING AND PARTICIPANTS The study was conducted from March 1999 to March 2000; 1000 patients, 63 pharmacists and 129 general practitioners from six Divisions of General Practice in South Australia participated. INTERVENTIONS A collaborative service delivery model, involving a preliminary case conference, a home visit and a second case conference, was agreed through discussions with medical and pharmacy organisations and then implemented. OUTCOME MEASURES Medication-related problems; actions recommended; actions implemented; and outcomes after actions taken. RESULTS Overall, 2764 problems were identified. The most common medication-related problem (17.5% of all problems) was the need for additional tests. Thirty-seven per cent of problems related to medicine selection, 20% to patient knowledge, and 17% to the medication regimen. Of 2764 actions recommended to resolve medication-related problems, 42% were implemented. Of the 978 problems for which action was taken and follow-up data were available, 81% were reported to be "resolved", "well managed" or "improving". CONCLUSION This implementation model was successful in engaging GPs and pharmacists and in assisting in the resolution of medication-related problems.
