The Republic of Korea has established an institutional framework to expedite the provision of rehabilitation sports public services to individuals with disabilities post-hospital discharge (Act on Guarantee of Right to Health and Access to Health Services for People with Disabilities in December 2017). Regrettably, this service remains non-operational to date. This study employs a service design approach to identify and develop essential elements for the effective implementation of public rehabilitation sports services in Korea. Adopting the service design method, including the empathize-define-ideate-prototype phases, co-creation activities were conducted with three teams comprising people with disabilities, caregivers, rehabilitation physicians, specialized sports instructors, facility managers, and government officials, emphasizing equitable distribution. By leveraging the experiences of people with disabilities, these teams collaboratively engaged in creative activities to formulate strategies for delivering prompt and user-friendly rehabilitation sports public services post-hospital discharge. Contributions from each team were meticulously collected and organized, incorporating diverse perspectives into the development of the Korean Rehabilitation Sports Public Service Information System (KRSPSIS). Additionally, we presented a scenario illustrating the practical application of the KRSPSIS. Through this system, we anticipate providing more efficient and convenient rehabilitation sports public services to individuals with disabilities during the critical early stages following hospital discharge.
