WHAT IS KNOWN AND OBJECTIVE: Warfarin is recognized as a high-risk medication for adverse events, and the risks are particularly heightened in the period immediately following a patient's discharge from hospital. This qualitative study aimed to explore the experiences of Australian patients and healthcare professionals of warfarin management in the post-discharge period and identify the benefits and deficiencies of existing systems, to inform the development of a model for a new collaborative post-discharge warfarin management service.
METHODS: Healthcare professionals, professional organization representatives and patients recently discharged from hospital taking warfarin (consumers) were recruited via purposive, criterion-based sampling within two Australian states. Semi-structured telephone interviews were conducted between August and October 2008 using standard discussion guides. Data were manually analyzed to identify emergent themes using a phenomenological approach.
RESULTS: Forty-seven participants were involved in the telephone interviews. Three major themes emerged: (i) appropriate warfarin education is integral to effective warfarin management, (ii) problems occur in communication along the continuum of care and (iii) home-delivered services are valuable to both patients and healthcare professionals.
DISCUSSION: Although high-quality warfarin education and effective communication at the hospital-community interface were identified as important in post-discharge warfarin management, deficiencies were perceived within current systems. The role of home-delivered services in ensuring timely follow-up and promoting continuity of care was recognized. Previous studies exploring anticoagulation management in other settings have identified similar themes. Post-discharge management should therefore focus on providing patients with a solid foundation to minimize future problems.
WHAT IS NEW AND CONCLUSION: Addressing the three identified facets of care within a new, collaborative post-discharge warfarin management service may address the perceived deficiencies in existing systems. Improvements may result in the short- and longer-term health outcomes of patients discharged from hospital taking warfarin, including a reduction in their risk of adverse events.
