The roles of doctors, nurses, and industrial hygienists in the healthcare management services in Korea: a comparison of the opinions of specialized health management institutions and entrusted enterprises: Bo-Young Jang, Dong-Mug Kang, Young-Ki Kim, Se-Young Kim, Kyung-Sun Ko; Ann Occup Environ Med 2018;30:50. Published online August 7, 2018; DOI: https://doi.org/10.1186/s40557-018-0261-9

Background

This study aimed to identify the difference of perception about the role of appointing health officers by comparing and analyzing the response of entrustment workplace (EW) and specialized health management institution (SI). This is considered an important aspect of an institutional assessment to improve the quality of health management services.

Methods

A survey questionnaire was mailed to 122 SIs and 319 EWs nationwide. The questionnaire survey was about the general characteristics of SIs and EWs and main occupations for each evaluation item. In total, 81 SIs (66.4%) and 30 EWs responded to the questionnaire. A logistic regression analysis was performed to compare the opinions of SI and EW.

Results

Based on the analysis, the items showing statistically significant differences were as follows. Doctors’ main tasks survey: “Guidance on their wearing personal protective equipment (PPE)” (OR: 4.58), “Guidance of improvement of work environment (WE)” (OR: 3.33), etc.; Nurses’ main tasks survey: “Guidance on their wearing PPE” (OR: 3.86), “Guidance for programs on health process in confined space (CS)” (OR: 0.36), “Guidance on the hearing conservation program (HCP)” (OR: 0.28), etc.; Industrial hygienist (IH)‘s main tasks survey: “Guidance of work through inspection (WTI)” (OR: 0.15), “Guidance on the improvement of WE” (OR: 0.32), “Management confirmation of substances used by process and Material Safety Data Sheet (MSDS)” (OR: 0.08), “Guidance on posting or keeping of MSDS and warning signs” (OR: 0.03), “Prevention of dust-induced medical problems” (OR: 0.28), “Guidance for programs of health process in CS” (OR: 0.39), etc.

Conclusions

It is necessary to educate the EWs to recognize the need for physicians to perform tasks, such as wearing a PPE, and instruction to improve WE. As for nurses’ tasks, such as education about the CS and the noise work, educating the nurses of the SI is regarded necessary as the demand of the EWs is considered. With respect to the unique tasks of IH, such as WE management and instructions for wearing PPE, among several other tasks of IH, training should be provided for improved IH recognition.

Background

We examined the current status of specialized agencies for occupational health management (SAs) and their workforce. Furthermore, we aimed to clarify the current practice status of SA healthcare professionals and factors that influence their performance.

Methods

To examine the current SA workforce, we analyzed data from the 2014 Survey of Current Status of SA and their Workforce from the Ministry of Employment and Labor (MOEL). Furthermore, we mailed out an original questionnaire to SA professionals to determine their current health management status and factors that affect their performance. Data from the respondents (N = 384) were analyzed.

Results

In 2014, the workforce performing health management in SAs comprised 232 physicians, 507 nurses, and 312 occupational hygienists, with no significant regional differences in the distribution of physicians and nurses. According to the findings of the questionnaire, the average daily number of worker consultations by physicians and nurses was 22.8, while the average time taken for health management ranged from 74.3 to 104.3 min, depending on the size of the firm. Most of the respondents (41.5%) answered that they were following-up on more than 80% of individuals with illnesses. Among health management tasks, performance scores of “consultations for general diseases” and “consultations for lifestyle habits” were relatively high, whereas health promotion activities at workplaces were relatively low. There was a significant correlation between the utilization of general and special health examination results and task performance.

Conclusion

Among health management tasks, follow-up management of individuals with illnesses and consultations for disease/lifestyle habits were relatively well performed, whereas health promotion activities at workplaces were not performed well. Among factors that positively influenced SA performance at workplaces, only the utilization of health examination results had significant effects. Therefore, to accomplish health management goals and perform effective health management at workplaces, there is a need to establish a comprehensive system of occupational health service outsourcing integrating health examinations and health management services. Furthermore, the current task system, which focuses on follow-up management, should be expanded to incorporate preventive and health promotion functions—the fundamental functions of occupational health services (OHS).

Air pollution and urinary n-acetyl-B-glucosaminidase levels in residents living near a cement plant: Min Soo Jung, Jae Yoon Kim, Hyun Seung Lee, Chul Gab Lee, Han Soo Song; Ann Occup Environ Med 2016;28:52. Published online September 29, 2016; DOI: https://doi.org/10.1186/s40557-016-0138-8

Abstract PDF PubReader ePub

Background

To identify adverse renal effects due to air pollution derived from a cement plant in Korea. Urinary n-acetyl-B-glucosaminidase (U-NAG) levels in residents living near a cement plant were compared to those in a group who lived farther away from the plant.

Methods

From June to August 2013 and from August to November 2014, laboratory tests for U-NAG and heavy metal were conducted on 547 study participants. Based on the level of air pollution exposure, subjects were divided into the “less exposed group,” (LEG) which consisted of 66 persons who lived more than 5 km away from the cement plant, the “more exposed group from the rural area” (MEG-R), which consisted of 272 persons, and the “more exposed group from downtown area” (MEG-D), which consisted of 209 persons who lived within a 1 km radius of the cement plant. U-NAG levels >5.67 U/L were defined as “higher U-NAG” levels. We compared the prevalence of higher U-NAG levels and estimated the adjusted odds ratio (OR) by air pollution exposure using a chi-square test and multiple logistic regression analysis. Further, we estimated the interaction between air pollution exposure and heavy metal exposure in renal toxicity.

Results

The OR of higher U-NAG levels by MEG-D and MEG-R compared to LEG was 2.13 (95 % CI 0.86–4.96) and 4.79 (95 CI 1.65–10.01), respectively. Urinary cadmium (U-Cd), urinary mercury (U-Hg), age, occupation, hypertension, and diabetes had a significant association with higher U-NAG levels. However, blood lead (B-Pb), sex, and smoking were not associated with higher U-NAG. Especially, concurrent exposure to heavy metals (U-Hg or/and U-Cd) and air pollution had an additive adverse effect. In the group with both 4^th quartile heavy metal exposure (U-Cd or/and U-Hg) and air pollution exposure, the OR in MEG-R and MEG-D was 6.49 (95 % 1.42–29.65) and 8.12 (95 % CI 1.74–37.92), respectively, after adjustment for age, occupation, hypertension, diabetes.

Conclusions

U-NAG levels seem to be affected by air pollution exposure as well as age, hypertension, diabetes, and even low levels of cadmium and low levels of mercury. Moreover, concurrent exposure to heavy metals and air pollution can have additive cytotoxic renal effects.

Published online June 30, 2012; DOI: https://doi.org/10.35371/kjoem.2012.24.2.133

Abstract PDF

OBJECTIVES
The purpose of this study was to develop a program applying participatory action-oriented training (PAOT) methods for the management of cardiovascular disease risk factors and to assess its effectiveness in the workplace.
METHODS
The cardiovascular disease risk factors of 817 workers in the workplace were assessed, and periodic health examination was conducted. Sixty-four workers (7.8%) were selected as a moderate-risk group and high risk group, and performed the participatory approach program for cardiovascular disease preventive management.
RESULTS
The sixty-four workers who participated in the participatory approach program made a total of 246 action plans, 3.8 action plans per person and 115 action plans were achieved after three months, so that 46.7% of action plans have been achieved. In the intervention group that participated in the program, the rate of smoking decreased from 36.2% to 8.6% and systolic and diastolic blood pressure significantly decreased from 140.0+/-9.4 mmHg to 134.2+/-12.3 mmHg and from 92.6+/-7.1 mmHg to 80.0+/-9.8 mmHg respectfully. In addition, risk factor score also decreased by 0.3, whereas the control group who did not participate in the program also showed a significant reduction in the mean systolic and diastolic blood pressure. Regular exercise increased from 8.5% to 16.0%.
CONCLUSIONS
To improve the effectiveness of the participatory approach program for the management of cardiovascular disease risk factors, the need to continues implementing programs and analysis of the long-term effects are required.

Comparison of Cardiovascular Disease Status Between Large Scale Industry Office and Self Employed Male Workers: Keun Ho Jang, Won Ju Park, Myeong Bo Kim, Dae Kwang Lee, Hong Jae Chae, Jai Dong Moon; Korean Journal of Occupational and Environmental Medicine 2011;23(2):130-138. Published online June 30, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.2.130

Abstract PDF

OBJECTIVES
The aim of this study is to compare the cardiovascular disease status between large scale industry office and self employed male workers who have gaps in their intensive health management.
METHODS
The cross sectional study was carried out with subjects composed of 244 shipyard office male workers and 381 self employed male workers, aged 30 to 55 years. They were given a health exam in a general hospital from January 2007 to June 2009. Information was based on data from self-administered questionnaires, physical examination and laboratory results on blood samples. The degree of coronary artery calcification and stenosis was evaluated by a 64 channel multi-detector computed tomography angiography.
RESULTS
The prevalence of hypertension(p<0.01) and diabetes mellitus(p=0.02) and waist circumference(p<0.01) was significantly lower in the shipyard office workers than in self employed workers. Proper drinking(p<0.01) was more commmon in shipyard office workers. The rates of coronary artery calcification and stenosis were estimated to be 18.4% and 11.5% respectively for shipyard office workers and were significantly lower than the 26.5% and 21.5% for self employed workers. After adjustment for age, the probability of coronary artery stenosis in shipyard office workers was lower than in self employed workers (OR=0.56, 95% CI=0.35~0.90).
CONCLUSIONS
The study results verified the benefits of a health promotion and intervention program and the healthy worker effect for cardiovascular diseases. More specifically, it verified the benefits regarding coronary artery stenosis in large scale industry office workers. This result should encourage the establishment of health promotion programs and the study of occupational epidemiology.

Cognition and Practice on Medical Information Protection of Iudustrial Health Care Manager of Small and Medium Sized Enterprises: Soo Jin Jeong, Min Kim, Chae Kwan Lee, Chang Hee Lee, Byung Chul Son, Dae Hwan Kim, Jeong Ho Kim, Jong Tae Lee, Goo Rak Chang, Ki Hun Hong, Chun Hui Suh; Korean Journal of Occupational and Environmental Medicine 2011;23(1):53-63. Published online March 31, 2011; DOI: https://doi.org/10.35371/kjoem.2011.23.1.53

Abstract PDF

OBJECTIVES
This research aimed to know the actual condition and problems of medical information protection at a workplace with the target of industrial health care managers of small and medium-sized enterprises.
METHODS
A self-administered questionnaire was given to industrial health-care managers of 216 enterprises from March 15 to May 17, 2010. The questionnaire was produced by referring to the Act on Personal Information Protection of Public Institutions, etc. This research evaluated agreement of cognition and practice according to 10 items of medical information protection using kappa and cross-analysis of significant factors between cognition and practice of medical information protection and general characteristics.
RESULTS
Cognition about medical information protection appeared to be 85.4-97.1% and its practice appeared to be 44.1-95.3%, so practice was lower than cognition. In addition, the agreement of cognition and practice appeared significantly low (kappa 0.082-0.387). The practice of medical information protection tended to be lower when the managers were older and held a higher job title. Health examination results were being delivered only to workers except for an employer (94.2%), but there were many industrial health-care managers who felt discomfort about their work in group occupational health-care systems (58.1%).
CONCLUSIONS
The practice of protecting medical information by industrial health-care managers was clearly lower than the cognition. Therefore, introduction of educational programs about personal information protection and provision of an independent place for group occupational health care service is urgent. In addition, in order to use the health examination results conveniently in group occupational health services, an institutional complement is necessary.

Abstract PDF

OBJECTIVES
This study was conducted to develop a worksite-based, post-examination, health care management system for continuous and systematic management of workers with hypertension, diabetes mellitus, hyperlipidemia, and abnormal LFT detected by periodic health examination and to assess the effectiveness such a system as an intervention study.
METHODS
Study subjects were selected from workers with hypertension, diabetes mellitus, hyperlipidemia, and abnormal LFT according to the selection criteria. The intervention group, but not the control group, received medical treatment of disease, follow up examination, and health education which consisted of information about the disease and the importance of life-style modification through periodic interview using the resources of occupational health service center in the worksite. To assess the effectiveness of this system, we compared follow up examination data from the intervention group with periodic examination data from the worksite control group.
RESULTS
In the intervention group a significant reduction trend was recorded for systolic and diastolic blood pressure, fasting blood sugar, postprandial 2 hour glucose, total cholesterol, triglyceride, LDL-cholesterol, AST, ALT, and gamma-GTP, and a rising trend for HDL-cholesterol. Significant group differences ware recorded for fasting blood sugar, postprandial 2 hour glucose, total cholesterol, AST, and ALT.
CONCLUSIONS
The worksite-based, post-examination, health care management system was effective for the continuous and systematic management of workers who had abnormal findings detected by periodic health examination.

Symptom prevalence and Primary intervention of work-related musculoskeletal disorders and their related factors among manufacturing workers: Hyunjoo Kim, Woo Cheol Jeong; Korean Journal of Occupational and Environmental Medicine 2005;17(2):116-128. Published online June 30, 2005; DOI: https://doi.org/10.35371/kjoem.2005.17.2.116

Abstract PDF

OBJECTIVES
To investigate the symptom prevalence and the primary intervention of work-related musculoskeletal diseases(WMSDs) and their related factors among manufacturing workers.
METHOD
A self-administered questionnaire survey was conducted on 2,457 workers, at 22 enterprises in Chungnam province, Korea, from September 1 to December 1, 2003. The contents of the questionnaire included general and work-related characteristics, musculoskeletal symptoms and workers' past one-year experience of primary interventions.
RESULTS
1. The overall symptom prevalence of the musculoskeletal diseases was 23.9%. The WMSD symptom prevalences at the neck/shoulder, arm/elbow, hand/wrist and back/leg were 14.8%. 2.7%. 7.3% and 12.0%, respectively. 2. In multivariate analysis, all WMSD symptom prevalences were high in the high workload, high force & high repetitiveness, and 'high job strain' groups. The WMSD symptom prevalence at neck/shoulder was also high in females and the group experiencing low social support from the supervisor. 3. The rates of the primary interventions were as follows : 13.7% for health education, 5.8% for health counselling, 18.8% for preventive exercise, 24.7% for ergonomic intervention, and 9.8% for administrative intervention. 4. In multivariate analysis, the size of the enterprises and the type of occupational health management system(OHMS) were significantly associated with all primary interventions except health counselling(p<0.05). The other individual-level predictive factors were as follows. Those for the health education were male and union presence. Those for the health counselling were older age(> or =40 years), irregular employment, and the active group of Karasek's job strain model. Those for the preventive exercise were male, older age, longer tenure and regular employment. Those for the ergonomic intervention were longer tenure, job of physical force and/or repetitiveness, high job stain and the group experiencing high social support from the supervisor. The predictive factor for the administrative intervention was male (p<0.05).
CONCLUSIONS
To establish an effective strategy for the primary prevention of WMSDs, approaches are needed which consider the individual nature of small and medium sized enterprises. IAlso necessary is to promote the participation of labor and management because the activation of the primary intervention was associated with the type of OHMS and union presence. Moreover the reduction of workload and increased intervention into the high risk group could be effective in the prevention of WMSDs.

Effectiveness and Factors Associated with the Control of Hypertension in Apartment Management Workers : Provided with Occupational Health Services: Soon Hwan Kang, Hyunjoo Kim, Youngkyu Kim, Jung Wan Koo; Korean Journal of Occupational and Environmental Medicine 2002;14(4):426-435. Published online December 31, 2002; DOI: https://doi.org/10.35371/kjoem.2002.14.4.426

Abstract PDF

OBJECTIVES
This study was conducted to investigate the effectiveness of the visiting occupational health services(OHS)and the factors associated with the proper control of blood pressure in hypertensive apartment management workers.
METHODS
The study group included 60 workers,who were visited and followed up regularly by a nurse for a period of more than 6 months.We checked the risk factors of hypertension, blood pressure and provided hypertension control methods every 2 months.
RESULTS
Mean systolic blood pressure decreased from 151.9 mmHg at the first visit to 141.1 mmHg at the last visit, and mean diastolic blood pressure also decreased from 93.6 mmHg to 87.1 mmHg (p<0.01).The number of workers who had regular exercise more than once a week increased from 7 (11.7%)at the first visit to 34 (56.7%)at the last visit, and the number of workers taking hypertensive medicines increased from 4 (6.7%) to 26 (43.3%)(p<0.01). The percentage of workers who either changed their life style or began taking hypertensive medication over the course of the action undertaken by the occupational health services showed a significant differences, 36.8%in the shorter intervention group, 43.5%in intermediate intervention group, and 72.2%in longer intervention group (p<0.05). Among those who were on shift work for less than 10 years was 32 (78.0%), while the corresponding number was only 9 (22.0%) for those who were on shift work for more than 10 years (p<0.01).
CONCLUSIONS
This study showed that the visiting OHS was effective in bringing about a reduction in blood pressure, as well as an improvement in life style habits and in the use of medication. It suggests that occupational factors should be taken into account for the proper control of blood pressure in hypertensive apartment management workers.

We tried to establish a Regional Occupational Surveillance System (ROSS) for estimating the prevalence and monitoring the trend of occupational dermatitis among 718 manufacturing workers exposed to organic solvents and nonmetallic chemicals in small and medium sized businesses of 1,2 industrial complex area of taejon City.
METHODS
Through the report from the nurses of Group Occupational Health Management System, we made a case referral and immediate health examination system with occupational medical clinics. We also performed a survey for detecting occupational dermatitis by a self-administered questionnaire. Case must meet 3 criteria; 1) He/She must have one or more significant cutaneous signs and symptoms. 2) The symptom should be changed by the work condition or caused by risk chemicals. 3) Dermatitis should be diagnosed by a doctor. Results Among the 131 workers(17. 7 %) with significant symptoms screened by the questionnaire, 4 workers(0. 6 %) met the case definition criteria. And among the 45 workers (6. 3 9o) referred to the immediate diagnosed system, 14 workers (l. 9 %) were Strongly suspected to have occupational dermatitis.
CONCLUSIONS
These prevalence rates were quite underestimated because of deficient recognition of the disease severity among the workers, reversibility of the target diseases, and life-threathening mood due to nationwide economic crisis and the socioeconomic withdrawal of each business. Ultimately, harmonized activities of government, industry, labor unions, volunteer organization and academy relating to occupational health in a community should be encouraged to do creative, consistent efforts for evolution and development of this first trial of ROSS.

Abstract PDF

The small scale industries in Korea are important in occupational health care management due to high accident rate and poor working condition. The authors surveyed the 4,811 small scale industries participated in the 1997 subsidiary program on health care management. The contents of survey were the general characteristics of the factory, the results of workers' general and occupational health examination, the results of workplace environmental monitoring, and the number of occupational accident and injured person at 1995 and 1996. We classified all industries by 67 groups. The prevalence of the general disease was higher in 'Manufacture of other fabricated metal productsj. rManufacture of textiles', 'Manufacture of basic metalsj. In occupational disease, that was higher in FManufacture of metal products', 'Manufacture of basic metals', so in environmental monitoring in 'Manufacture of textiles', 'Manufacture of other fabricated metal products' 'Printfrig' in occupational injuries in 'Manufacture of chemical products', 'Manufacture of basic metals'. However the factories of 'manufacture of motor vehicle', 'manufacture of machine and equipment', 'manufacture of electric product' in the program are large in magnitude, but less important in occupational health management. We observed that the prevalence of general disease, occupational disease, workplace environmental monitoring, occupational injuries of subsidized industries in 1996 were increased compared with those in 1995. and were larger than those of nationwide statistics. These phenomenon shows that the subsidiary health program for participated industries is important and to be urgent. We observed that the major groups in district were different and so the approaching method of each district must be various and different. And the health program manager should focus on the C grade in health examination and the action level in workplace monitoring more than the D grade and the permissible level.

Some Renal Function Indices in Workers Occupationally Exposed to Lead: Je Sung Nam, Yong Bae Kim, Hyun Cheol Ahn, Hwa Sung Kim, Gap Soo Lee, Kyu Yoon Hwang, Sung Soo Lee, Kyu Dong Ahn, Byung Kook Lee; Korean Journal of Occupational and Environmental Medicine 1998;10(2):139-148. Published online May 31, 1998; DOI: https://doi.org/10.35371/kjoem.1998.10.2.139

Abstract PDF

The influence of lead exposure on renal function was studied. Three hundred forty two male lead exposed workers who worked in 3 storage battery factories, 5 secondary smelting factories and 3 litharge making factories, and 60 male control workers who were not exposed to lead occupationally were chosen for this study. Blood lead (PbB), zinc protoporphyrin in whole blood (ZPP) and delta-aminolevulinic acid in urine (DALA) were selected as indicators of lead exposure. As indicators of renal function blood urea nitrogen(BUN) , serum creatinine(S-Cr), serum uric acid (S-UA), N-acetyl-beta-D-glucosaminidase in urine (NAG) and urine protein (U-TP) were selected. While the mean values of lead exposure indicators of lead workers were significantly different from non-exposed ones, the mean values of renal function indicators of exposed except S-UA were significantly different from non-exposed. The frequency of workers whose value of renal function indicators were over the nor mal criteria (BUN>20 mg/dl ; S-Cr>1.2 mg/dl ; S-UA>7.0 mg/dl ; NAG>8.0 U/liter; U-TP>8.0 mg/dl) by the level of lead absorption in terms of PbB, ZPP and DALA were calculated. Age adjusted odds ratio of over the normal value of BUN and NAG were statistically significant by the level of ZPP and that of BUN only showed the dose-dependant relationship. But the frequency of over the normal criteria of renal function indicators were not increased by the level of PbB and DALA. On stepwise multiple regression using renal function indicators as a dependent variable and each lead exposure indicator and age as independent variables, only BUN, NAG and U-TP were contributed by the lead exposure indicators. It was found that only NAG of renal function indices was most reliable indicator who showed dose-response relationship with lead exposure and the measurement of NAG for lead workers whose relatively high exposure is highly recommended.

Abstract PDF

This study was conducted to find out the characteristics, type of the duty and job satisfaction of health care managers at the worksite. The subjects of this study were 306 health care managers serving at worksite situated in Kyungin presently in 1994, concerning their job. Major depedent variables were health management, environmental management, and health planning related with health care managers' job; these variables were measured by nominal scale consisted of 9 items respectively. The collected data were analysed and some major results are as follows; 1. It appeared that according to the qualification of health care managers, nurses showed high performing rate in duty of health managerment and health planning, Industrial hygienist showed high performing rate relating to working environmemt managemant, and regarding their holding an additional post, the number of environmental managers held more an additionnal post than other qualified managers, thereby showing significant relatively, and however, no relation with qualification was there in decision making. 2. The performing rate relatiag to health management was significantly correlate with female, youth, unmarried, higher education, general affairs in post of duty, general employee in position, only duty of health, low monthly income and nurse. But, the performing rate relating to environmental management was significantly correlate with manufacturing industries, industrial health and safety committee, male, old age, married, long work duration, additional post, high monthly income, and hygienist and environmental managers. The performing rate relating to health planning was significantly correlate with the performing rate relating to health and environmental management, but the performing rate relating to health management was not significantly correlate with the performing rate relating to environmental management. 3. In multiple regression analysis, common major determinants of the performing duty relating to health management, environmental management and health planning were industrial health and safety committee, type of industry, education, and qualification of industry's health care managers. Additionally, age was selected as highly correlated with the performing duty relating to environmental management, and work duration and post of duty of health care managers in industry were selected as highly correlated with the performing duty relating to health planning, Based on the results indicated above, it could be understood that characteristics of the worksite-industrial health and safety committee, scale and types of industry, and characteristics of health care managers-age, education, post of duty, work duration and qualification had relations with their type of the duty. Therefore, it is required that the reference to the above-showing results such as guiding for them to precisely grasp their performing duty according to their qualification, heightening their participation in decision-making, extending the industrial health service, etc., operation and management of health care managers at the worksite should be made into being more efficient.
