Development of a Baseline Checklist for CTD Risk Assessment: Donghyun Park, Sang Hwan Han, Dong Bin Song; Korean Journal of Occupational and Environmental Medicine 1998;10(2):251-266. Published online May 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.2.251

Abstract PDF: Today, CTDs (Cumulative Trauma Disorders) are one of major hazards in the US and European Industries disrupting work schedules, productivity and increasing workers compensation costs. The increase in injuries and their associated costs has led companies to form committees and implement programs to address this problem. Therefore, it is important that quantitative analysis tools help identify and assess industrial tasks that pose risk to workers. However, the process of quantifying risk in upper limb tasks is still in its infancy stage and calls for better measurement techniques are not going unheard. As the first work of quantification, baseline CTD checklist for risk assessment was developed in this study. It was mainly based on previous literature regarding CTDs. The checklist was unique in that its expected user was industrial hygienist who did not have much ergonomic background and in that it was targeted to Korean workers in various types of industries. As the first application of the checklist, some jobs in two industries (VDT, heavy Industry) were evaluated, and compared with the medical data. Eighteen out of thirty items in the checklist was univariately significant (p<0.05) on the results of medical examinations. The correlation between medical data and total risk score from the checklist was 0.62. The feasibility of its use by an industrial hygienist was also checked by comparing with the results by an ergonomist. Their correlation (on the basis of Kendall's tau-b) in terms of total risk score was 0.74. The checklist in this study shows reasonably good performance for the first trial. Further research will have to include continuous refinement and validation for many more industries and many more jobs.

Cumulative Trauma Disorders Among Shipyard Workers and Application of Baseline Checklist for Risk Assessment: Sang Hwan Han, Nam Jong Paik, Donghyun Park, Ki Eon Jang, Myung Hag Lee, Jong Tae Park, Dae Sung Kim, Yeon Sook Lee, Kyung Ja Paik, Young Soo Shin, Dong Bin Song; Korean Journal of Occupational and Environmental Medicine 1997;9(4):579-588. Published online December 31, 1997; DOI: https://doi.org/10.35371/kjoem.1997.9.4.579

Cumulative trauma disorders were surveyed in a cross-sectional study of 100 male ship yard workers and 43 male office workers. And baseline checklist for risk assessment of cumulative trauma disorders was applicated in a ship making process. Cases of cumulative trauma disorders were defined using physical examinations and electronic diagnostic methods. Data on demographics, individual factors (medical condition), work organization and psychosocial aspects of work were obtained by questionnaire. Association between the above factors and cumulative trauma disorders were assessed by multiple logistic regression models. 29(29 %) participants of male shipyard workers and 4(9.2 %) study subjects of male office workers met our case definitions for cumulative trauma disorders. The myofascial pain syndrome of neck muscles(12 % of participants) and carpal tunnel syndrome(5 % of participants) were the major two medical conditions in shipyard workers. The odds of male shipyard workers for cumulative trauma disorders to male office workers was 3.15 after adjustment of age(95 % C.I. :2.25-5.44). And the variables such as duration of present job, HIVD condition, and surges in workload were associated at least one of the cumulative trauma disorders in the final models (p<0.05) . This study indicates that work related upper extremity musculoskeletal disorders are relatively common among shipyard workers, and shows that the psychosocial factors is not likely to be related to the occur rences of these disorders in heavy workers. Also we developed baseline checklist for risk assessment of cumulative trauma disorders. The checklist was unique in that its expected users were industrial hygienists and occupational healthing nurses who did not have much ergonomic background and in that it was targeted to Korean workers in various types. As the first application of the checklist, shipyard workers were evaluated.
