Purpose: This study aimed to report on the multidisciplinary web conferences for patients with heart failure to strengthen medical collaboration and provide seamless support. Method: We described and analyzed the web conferences by retrospectively collecting data on the conferences. Result: Main subjects of the conferences were those who lived alone and had inadequate nursing care, and those to whom the intervention of multidisciplinary professionals needed to be strengthened to prevent readmission. Using web conferencing tools, we shared issues and solutions for discharge with considering the anonymity of the patient’s personal information. The conferences were held once weekly for 30 minutes when the patients were in the stages of preliminary discharge planning. Participating physicians and healthcare professionals included cardiologists, nurses, pharmacists, physical therapists, nutritionists, palliative care physicians, and home doctors. The cardiology staff used a multifaceted checklist to clarify issues while sharing the patient’s condition and treatment plan. The palliative care physicians made suggestions about value-based treatment plans and decision support, and the home doctor made suggestions about home services, drug adjustment, and lifestyle guidance necessary to prevent readmission. Discussion: Further improvement in the web conferences and evaluation on the effect of the conferences are needed.
