Objectives: This study was conducted to analyze the factors that affected the decision of claims for
cerebrovascular disorders and cardiovascular diseases in chronically overworked workers, that submitted
their claims after the reformation of approval standards in the Industrial Accident Compensation
Insurance Act on 1 July 2008.
Methods: Of 2909 cases, who claimed between January 1. and December 31. 2009, 1046 cases were
selected based on their worker’s compensation record and investigated following 6 provincial committees
for work-related diseases. The approval rate and odds ratio were analyzed with respect to the general
characteristics, past medical history and work-related information using a logistical regression and
Student t-test.
Results: Of the 1046 selected cases, the approval rate was 18.5%(194 cases). In the multivariate logistical
regression analysis, the factors for approving cerebrovascular disorders and cardiovascular diseases
as work-related diseases were found to be the average working time over the last 1 week, occupational
category, gender, age, death or survival, the presence of an associated disease, claimed province, and
smoking.
Conclusion: Factors for approving claims of cerebrovascular disorders and cardiovascular diseases as
work-related diseases were the average working time over last 1 week, gender, age, death or survival,
claimed disease, presence of associated disease, claimed province, smoking.
