Disability Pensions due to Skin Diseases: A Cohort Study in Swedish Construction Workers

Incidence rates of injury, musculoskeletal, skin, pulmonary and chronic diseases among construction workers by classification of occupations in South Korea: a 1,027 subject-based cohort of the Korean Construction Worker's Cohort (KCWC)

Background

The objective of this study is to investigate the differences in incidence rates of targeted diseases by classification of occupations among construction workers in Korea.

Methods

In a subject-based cohort of the Korean Construction Worker's Cohort, we surveyed a total of 1,027 construction workers. As occupational exposure, the classification of occupations was developed using two axes: construction business and job type. To analyze disease incidence, we linked survey data with National Health Insurance Service data. Eleven target disease categories with high prevalence or estimated work-relatedness among construction workers were evaluated in our study. The average incidence rates were calculated as cases per 1,000 person-years (PY).

Results

Injury, poisoning, and certain other consequences of external causes had the highest incidence rate of 344.08 per 1,000 PY, followed by disease of the musculoskeletal system and connective tissue for 208.64 and diseases of the skin and subcutaneous tissue for 197.87 in our cohort. We especially found that chronic obstructive pulmonary disease was more common in construction painters, civil engineering welders, and civil engineering frame mold carpenters, asthma in construction painters, landscape, and construction water proofers, interstitial lung diseases in construction water proofers.

Conclusions

This is the first study to systematically classify complex construction occupations in order to analyze occupational diseases in Korean construction workers. There were differences in disease incidences among construction workers based on the classification of occupations. It is necessary to develop customized occupational safety and health policies for high-risk occupations for each disease in the construction industry.

Contact Dermatitis in Construction Workers in Northeastern Italian Patch Test Database Between 1996 and 2016

BACKGROUND

Contact dermatitis in construction workers (CWs) is frequent due to the widespread exposure to sensitizing substances and irritating agents and the wet and cold working conditions.

OBJECTIVE

Our objectives were to evaluate contact dermatitis characteristics among CWs who underwent patch test in northeastern Italy and to identify related allergens.

METHODS

Seven hundred ninety-five CWs were studied and their data were compared to 2.099 male white-collar workers. The associations between patch test results and occupations were assessed by multivariate logistic regression analysis. Incidence data were calculated from 1996 to 2016.

RESULTS

CWs with confirmed occupational dermatitis presented an increased risk to be sensitized to potassium dichromate [OR 3.1 (95%IC 2.0-4.8)], to thiurams [OR 8 .6 (95%IC 4.0-18.4)], and to epoxy resins [OR 12.7 (95%IC 6.1-26.4)]. Sensitization to chromate decreased significantly after 2004, following EU regulation of chromate content in concrete, while sensitization to epoxy resins and thiurams increased. The overall incidence of occupational contact dermatitis in CWs decreased significantly.

CONCLUSION

Our study demonstrated the effectiveness of EU regulations in reducing chromate sensitization in CWs and the overall incidence of occupational contact dermatitis. However, sensitization to other haptens is increasing, though improvement of protective measures is compulsory.

Estimating the public economic consequences of cardiovascular disease-attributable events and evolocumab treatment in Australia

BACKGROUND

Following cardiovascular events, individuals often make choices about their working life that pose fiscal costs for the government in relation to lost tax revenue, increasing disability or early retirement. We evaluate the fiscal consequences for the Australian Government in atherosclerotic cardiovascular disease (ASCVD) patients with low-density lipoprotein >3.3 mmol/L after the maximum tolerated doses of a statin or when contraindicated or intolerant to statins, compared to evolocumab added to the standard of care.

METHODS

The natural history of patients with ASCVD was evaluated using a multi-state Markov cohort model comparing evolocumab with current treatment practices. Published rates for the likelihood of being disabled and retiring prematurely in patients experiencing stroke or myocardial infarction were modeled. Reported government costs for annual disability payments and lost tax revenues from the nationally representative STINMOD + data set were used to estimate the fiscal consequences associated with attributable ASCVD events.

RESULTS

The incremental tax gain associated with evolocumab in someone aged 40, 50 or 60 results in additional tax revenues of Aus$15,716, Aus$9,810 and Aus$4,217, respectively. Cost-savings attributed to disability payments of Aus$3,483, Aus$2,495 and Aus$4,619 were observed in those aged 40, 50 and 60, respectively. The ratio of evolocumab to fiscal benefits indicates that up to 52% of evolocumab costs are offset by future lifetime taxes paid and reduced social benefits payments in those treated aged 40. The ratio of fiscal benefits to costs in treating those aged 50 and 60 were 37% and 31%, respectively.

CONCLUSIONS

Applying a cross-sectorial government perspective budget impact assessment improves our understanding of fiscal changes attributed to ASCVD based on changes in premature mortality and work activity and how this influences lifetime tax contributions and public benefits. The main cost driver observed was associated with reduced ASCVD events that enabled people to remain productive and paying taxes.
