This study aimed to explore the educational outcomes of home-based warfarin education provided by trained pharmacists. Methods In a prospective, non-randomised, controlled cohort trial, patients received either usual community-based post-discharge care or a post-discharge warfarin management service, including warfarin education by trained pharmacists during two or three home visits. Patients’ warfarin knowledge was assessed at 8 and 90 days post-discharge using the Oral Anticoagulation Knowledge test. Key findings One hundred and thirty-nine patients were recruited into the usual care group between November 2008 and August 2009, and 129 into the intervention group between May and December 2009. Pharmacist-delivered warfarin education was associated with a significant difference between the intervention patients’ baseline and day 8 mean warfarin knowledge scores of 64.5% (95% confidence interval (CI) 61.0–68.5%) and 78.0% (95% CI 74.5–81.5%; P < 0.001), respectively. The intervention patients also scored significantly higher than the usual care patients at day 8 (65.0%, 95% CI 61.5–68.0%; P < 0.001), but not at day 90. Conclusions Use of an existing healthcare framework overcame several systemic barriers by facilitating warfarin education in patients’homes.While the intervention was associated with better short-term warfarin knowledge, follow-up may be required to optimise its benefits.Widespread implementation of home-based warfarin education by pharmacists has the potential to contribute significantly to improved outcomes from warfarin therapy.
