Abstract
BACKGROUND: Exercise is recommended to prevent dialysis; however, the involvement of physical therapists is not a criterion for reimbursable medical fee calculation in Japan. Consequently, eligible patients may not receive appropriate exercise guidance. We aimed to clarify the extent of physical therapist participation in dialysis-prevention interventions reimbursed under the current Japanese healthcare system and to identify reasons for non-participation related to reimbursement criteria. METHODS: In January 2025, a 30-item questionnaire was distributed to all facility representatives registered with the Japan Physical Therapist Association to investigate medical fees and physical therapist involvement in dialysis prevention. Dialysis-prevention interventions were defined as those reimbursed under the Japanese healthcare system: Lifestyle-Related Disease Management, Diabetes Dialysis Prevention Guidance and Management (including Guidance of Patients with Severe Renal Impairment), and Chronic Kidney Disease (CKD) Dialysis Prevention Guidance and Management. RESULTS: Of the 10,285 facilities surveyed, 1322 (12.9%) responded. Among these, physical therapists participated in Lifestyle-Related Disease Management, Diabetes Dialysis Prevention Guidance and Management, and CKD Dialysis Prevention Guidance and Management in 4.8%, 3.5%, and 2.3% of facilities, respectively. The most frequently cited reasons for exclusion were "Inclusion of physical therapists is not a strict requirement for medical fee reimbursement," "Insufficient personnel or time," and "No role assigned by the dialysis-prevention team." CONCLUSION: Physical therapist involvement in dialysis-prevention interventions was limited, primarily due to current medical fee reimbursement criteria. Revising the healthcare system to facilitate their inclusion may enhance the delivery of exercise-based preventive care.
