Occupational Exposure to Streptococcus suis among US Swine Workers

Despite numerous cases of human infection with Streptococcus suis worldwide, human disease is rarely diagnosed in North America. We studied 73 swine-exposed and 67 non–swine-exposed US adults for antibodies to S. suis serotype 2. Serologic data suggest that human infection with S. suis occurs more frequently than currently documented.     

Occupational Injuries of Aquaculture Workers: Washington State

Objective: To characterize occupational injuries of aquaculture workers in Washington State.

Methods: We reviewed accepted Washington State workers’ compensation claims from January 1, 2006 to December 31, 2014. Trends in employment, worker demographics (including age, sex, and body mass index), claim rate, and injury characteristics were summarized for accepted claims in the Washington State risk classes that include aquaculture workers.

Results: During the nine-year study period, there were 1,180 accepted claims, 836 (65.1%) were medical-aid only and 344 (26.8%) were compensable. Most commonly reported injury types included being struck by/against an object (n = 420) and work-related musculoskeletal disorders (n = 310). Over the study period, there was no statistically significant change in claim rates in aquaculture (p = 0.77), though they were elevated compared to claim rates for all WA industries combined. A significant upward trend (p = 0.003) in aquaculture employment was observed during our study period.

Conclusions: Given the growth in aquaculture production, and that aquaculture workers in Washington are experiencing higher occupational injury rates compared to other workers in the state, our study suggests that the industry should devote greater attention to prevention of work-related injuries, especially those resulting in being struck by/against objects or work-related musculoskeletal disorders. Enhanced occupational safety and health programs for this industry could help reduce injuries, as well as the cost of workers’ compensation claims.

Stuck at the Bottom Rung: Occupational Characteristics of Workers with Disabilities

Introduction The proportion of workers reporting disabilities varies tremendously across occupations. Although differences in the occupational distributions may partly explain the large disparities in earnings and job security between workers with and without disabilities, little is known about the reasons that workers with disabilities are underrepresented in certain occupations and overrepresented in others. Methods Using a large, national survey of the US population combined with official data on the skill and experience requirements and occupational risks of 269 occupations, a multilevel regression analysis was performed to identify occupational and individual factors that influence the representation of workers with disabilities across occupations. Models of overall, sensory, mobility, and cognitive disability were constructed for working-age labor force participants, as were models of overall disability for younger, in-between, and older workers. Results At the occupational level, reported disability is negatively associated with occupational requirements for information and communication skills and with the amount of prior work experience that is required, after controlling for individual factors such as age and educational attainment. Little relationship is found between disability status and a set of occupational risk factors. These findings generally hold true across disability types and age groups. Conclusions Even after taking into account their lower average educational attainment, workers with disabilities appear to be disproportionately relegated to entry-level occupations that do not emphasize the better-remunerated job skills. Underemployment results in lower wages and less job security and stability. Possible reasons include employer discrimination, low expectations, deficits in relevant skills or experience, and work disincentives.

Epidemiology of Occupational Injuries Among Insured Workers in Saudi Arabia Between 2004 and 2016

This is a retrospective analysis of annual reports on occupational injuries issued by the national social insurance agency of the Kingdom of Saudi Arabia (KSA) for the years 2004 through 2016. For each criterion we calculated an index based on the equation N_Y/N_ref x100, where N_Y is the number of occupational injuries by a specific criterion in a specific year Y, and N_ref is the number of injuries in the corresponding criterion in the reference year, i.e. 2004. We also calculated the number of injuries to number of workers ratio (N_i/N_w) for different occupations and economic sectors to get a clearer idea of the injury trends per worker. In terms of occupational injury rates (with respect to 2004), we observed increases in construction, financing & real estate (economic sectors), among engineers and technicians (occupations), in infections and secondary contusions (injury type), for upper and lower limbs (affected body parts), over falls and “other” causes. Most injuries occurred on Fridays, which is a weekend day in Saudi Arabia. We also observed increased recovery without disability (injury status). However, if we look at the number of occupational injuries per worker, we can see a decreasing trend over time for all occupations and economic sectors, most likely thanks to improved labour law and safety at work practices for insured workers. Our findings are similar to reports from other Persian Gulf countries and reflect current labour health and safety issues in the area.Key words: construction workers, contusions, engineers, General Organization for Social Insurance, infections, labour, Persian Gulf countries, technicians     

Occupational and Nonoccupational Correlates of Alcohol Consumption in Urban Transit Operators

Background. The influence of occupation and the worksite has emerged as an important area of study in research on alcohol consumption. Occupational and nonoccupational factors were studied in relation to alcohol consumption using data from a 1983-1985 cross-sectional study of transit operators. Methods. A total of 1,853 operators underwent a medical examination for driver′s license renewal (including information on age, ethnicity, gender, education). Of these operators, 1,448 completed a questionnaire about occupational (e.g., time of shift, job stressors) and nonoccupational (e.g., personality, life stressors) factors. From either the medical examination or the questionnaire, weekly alcohol consumption was available for 1,820 operators. Variables related to alcohol consumption in previous studies, or theoretically linked to consumption, were analyzed in relation to heavy (≥15 drinks/week) and average weekly consumption. Results. Heavy and average consumption were both related to several nonoccupational variables, including demographic (age, ethnicity, gender, marital status), personality (depression, anger expression), and life stress variables (i.e., life events). Heavy and average consumption were also related to several occupational variables, including job history (number of years driving, specific worksite) and job stressors. Neither measure was related to subjective job content (job demand, decision latitude). Conclusions. Variability in consumption by demographic factors among this population reflects that seen in society as a whole. However, occupational factors may influence consumption, since consumption was strongly related to (a) specific worksite and time of shift and (b) reported job stressors. Clarifying the exact influence of occupational and worksite factors on alcohol consumption will depend on the convergence of findings from different research designs (e.g., cross-sectional, longitudinal, ethnographic).

The Therapeutic Use of Computers in Occupational Therapy With Patients With Closed Head Injuries

Occupational therapists in various settings were surveyed to obtain information on their use of computers with closed head injured patients. The majority of therapists use micro-computers for cognitive rehabilitation followed by vocational rehabilitation. Respondents indicated that an efficient means of distributing information does not yet exist resulting in a high incidence of trial and error learning on the part of the therapist.     

Occupational Injuries in Ghana

Abstract

Household interviews were used to survey 21,105 persons living in 431 urban and rural sites in Ghana, to determine the nature and extent of their occupational injuries. Annual occupational injury rates were 11.5 injuries/1,000 persons in the urban areas and 44.9/1,000 in the rural areas. Occupational injuries had higher mortality, longer disability, and higher treatment costs than non-occupational injuries. There were substantial occupational injury rates among children, especially in rural areas. In the urban areas, the largest numbers of injuries were to drivers (12.7% of urban occupational injuries) and traders (19.4%), most of which were road-traffic-related. In the rural areas, most injuries (71.6%) were to farm workers. Occupational injuries are a substantial burden in Ghana. Priorities include improving road safety and improving the prevention and treatment of injuries from nonmechanized farming.     

Medical Expenditures Associated with Nonfatal Occupational Injuries among Immigrant and U.S.-born Workers

ABSTRACT: BACKGROUND: No national study has investigated whether immigrant workers are less likely than U.S.-workers to seek medical treatment after occupational injuries and whether the payment source differs between two groups. METHODS: Using the 2004-2009 Medical Expenditure Panel Survey (MEPS) data, we estimated the annual incidence rate of nonfatal occupational injuries per 100 workers. Logistic regression models were fitted to test whether injured immigrant workers were less likely than U.S.-born workers to seek professional medical treatment after occupational injuries. We also estimated the average mean medical expenditures per injured worker during the 2 year MEPS reference period using linear regression analysis, adjusting for gender, age, race, marital status, education, poverty level, and insurance. Types of service and sources of payment were compared between U.S.-born and immigrant workers. RESULTS: A total of 1,909 injured U.S.-born workers reported 2,176 occupational injury events and 508 injured immigrant workers reported 560 occupational injury events. The annual nonfatal incidence rate per 100 workers was 4.0% (95% CI: 3.8%-4.3%) for U.S.-born workers and 3.0% (95% CI: 2.6%-3.3%) for immigrant workers. Medical treatment was sought after 77.3% (95% CI: 75.1%-79.4%) of the occupational injuries suffered by U.S.-born workers and 75.6% (95% CI: 69.8%-80.7%) of the occupational injuries suffered by immigrant workers. The average medical expenditure per injured worker in the 2 year MEPS reference period was $2357 for the U.S.-born workers and $2,351 for immigrant workers (in 2009 U.S. dollars, P=0.99). Workers' compensation paid 57.0% (95% CI: 49.4%-63.6%) of the total expenditures for U.S.-born workers and 43.2% (95% CI: 33.0%-53.7%) for immigrant workers. U.S.-born workers paid 6.7% (95% CI: 5.5%-8.3%) and immigrant workers paid 7.1% (95% CI: 5.2%-9.6%) out-of-pocket. CONCLUSIONS: Immigrant workers had a statistically significant lower incidence rate of nonfatal occupational injuries than U.S.-born workers. There was no significant difference in seeking medical treatment and in the mean expenditures per injured worker between the two groups. The proportion of total expenditures paid by workers' compensation was smaller (marginally significant) for immigrant workers than for U.S.-born workers.
