Transitional periods, such as patient discharge, are notably challenging. This study aimed to explore the perceptions of providers involved in hospital discharge support programs, identify the primary obstacles, and propose strategies for improvement. In this qualitative cross-sectional study, we interviewed 49 healthcare professionals, comprising doctors, nurses, and social workers, who participated in two pilot programs. We organized focus group interviews with 3-6 participants per group, segmented by the type of discharge support program and profession. For data analysis, we employed phenomenological analysis, a qualitative method. Participants recognized the importance of the discharge support program and anticipated its benefits. The Rehabilitation Hospital Discharge Patient Support Program saw more active involvement from doctors than the Establishment of a Public Health-Medical Collaboration System program. Both programs highlighted the critical need for more staff and better compensation, as identified by the doctors. Nurses and social workers cited the heavy documentation burden, uncooperative attitudes from patients and local governments, and other issues. They also anticipated that program improvements could be achieved through the standardization of regional welfare services and better coordination by local governments serving as welfare service regulators. All groups-doctors, nurses, and social workers-underscored the significance of promoting these programs. Discharge support programs are crucial for patients with functional impairments and severe illnesses, particularly in ensuring continuity of care. Policy support is essential for the successful implementation of these programs in South Korea.
