In order to obtain information useful in setting up occupational rehabilitation programs, an evaluation was conducted to determine predictive factors of workers' return to work after an occupational injury.

13, 903 records of registered occupationally injured cases identified to have received disability compensation in 1998 were collected from the 36 branch of Korean Labor Welfare Corporation(KLWC). Through simple systematic sampling, a total of 3, 658 cases were selected as final subjects. Status of return to work, general characteristics, workplace characteristics, disability characteristics and disability outcome characteristics were collected from the KLWC and National Health Insurance Corporation records(NHIC). For statistical analyses, chi-square test and stepwise multiple logistic regression analysis were applied using the SAS software package program.

Negatively affecting significant predictive factors for return to work were included the female gender, age of 50 years or older, 6 month or less of work duration, 1 or less family dependents, workplace with 200 or less employees, electric, gas, waterwork companies, foot injuries compared to finger injuries, fall from elevation, high degree of disability claims(1~4 grade), and period of medical care more than 181 days.

The results suggest that the poor rate return to work in occupationally injured workers' is particularly affected by female gender, older-aged employees, and workers employed by electric, gas, waterwork companies. Also, it was more difficult to return to work for workers who received injuries from a fall from elevation and who had longer period of medical care(more than 181days). It is strongly recommended that more efficient and systematic occupational rehabilitation programs be set up, taking into consideration the above mentioned factors.
