P-594 a Preliminary Study on the Active Case Management Model of Workers With Work-Related Injuries in Kaohsiung City: Association Between Return to Work, Instrumental Activities of Daily Living, and Business Category

Introduction There are hundreds of deaths in Taiwan every year due to major occupational accidents. Most common problem in major occupational accidents is that victims do not have access to immediate occupational medical resources. Therefore, our goal is to provide workers with immediate occupational medical resources and case management, and to assess what are important factors for successful recovery and return to work (RTW). Methods We arranged case management for workers with work-related injuries and hospitalization. Our implementation strategies for the new model included: (1) occupational medicine team visit workers in wards; (2) assist workers to follow up in the outpatient clinic after discharge; (3) phone visit after three months to confirm the recovery, RTW, functional status, etc. Results During November 2022 and May 2023, our team took care of a total of 83 hospitalization workers. The score of Activities of Daily Living (ADL) after 3 months was 96.63±11.90 (p value<0.001), Instrumental Activities of Daily Living (IADL) after 3 months was 22.89±2.32 (p value<0.001), compared with initial status. Regression model revealed successful RTW was significantly positively associated with IADL after 3 months (β 0.755, odds ratio [OR] 2.128, 95% confidence interval [CI] 1.215-3.724, p value 0.008) while negatively associated with patients who working in manufacturing business category (β -2.601, adjusted OR 0.074, 95% CI 0.006-0.894, p value 0.04). Discussion and conclusion The new case management model can facilitate occupational accident worker recovery and RTW smoothly. Workers with better IADL and who work in non-manufacturing business categories have higher successful RTW after 3 months of occupational accident
