Work-related musculoskeletal disorders and injuries: differences among older and younger occupational and physical therapists

INTRODUCTION

Occupational and physical therapists are at significant risk of work-related musculoskeletal disorders and injuries. As the therapy workforce ages, and shortages of therapists are predicted, it is important to evaluate differences in injuries and injury behaviors between older and younger therapists.

METHODS

Half of all occupational and physical therapists practicing in Wisconsin were randomly selected for a cross sectional study examining the relationship between aging and characteristics of self-reported work injuries and musculoskeletal symptoms.

RESULTS

Data from a sample of 1,158 therapists revealed older workers to have similar injury incidence rates, however, days away from work due to injury were higher among older workers. Overall, older and younger therapists were more similar than different, especially in regards to work behaviors. Older therapists tended to report more severe pain symptoms than younger therapists and were two and a half times more likely to report that they changed jobs due to their pain symptoms.

CONCLUSIONS

Older and younger therapists have similar work-related injury experiences. Older workers may be more vulnerable to lost work time and may experience more severe pain symptoms. Many interventions exist to prevent work-related injuries to therapists and more guidance in the best way to integrate these interventions (e.g., mechanical lift devices) into therapy practice is needed.

Gender and age distribution of occupational fatalities in Taiwan

This study analyzed fatal occupational injuries in Taiwan. One thousand eight hundred ninety work-related accident reports filed in the years 1996-1999 were extracted from the annual publication of the Council of Labor Affairs (CLA). These data were analyzed in terms of gender, age and work experience of the accident victim as well as accident type and the work-related source of injury to identify significant contributing factors. The CLA data showed that work-related falls were the leading cause of work-related fatalities in both male and female workers (38.2% of male victims and 39.2% of female victims). Gender differences were also noted in the accident type and age of the injured workers. Male workers had a significantly higher prevalence of fatal occupational injuries than female workers throughout the analyzed period (7.4 compared to 0.9 per 100,000 full-time workers). Young males aged 24 years or less had the highest rate of fatal occupational injuries. The finding that gender and age are major factors in occupational injuries is a significant finding in the field of occupational safety and may be helpful for developing accident prevention programs.

Meeting the challenges of an aging workforce

BACKGROUND

Demographic, labor market and economic forces are combining to produce increases in the number and percentage of U.S. workers 55 and older. In some ways these workers will be our most skilled and productive employees but in others the most vulnerable.

METHODS

The literature on aging and work was reviewed, including demographic trends, physical and cognitive changes, safety and performance, work ability, and retirement patterns.

RESULTS AND CONCLUSIONS

Older workers have more serious, but less frequent, workplace injuries and illnesses than younger ones. There is evidence that many of these problems can be prevented and their consequences reduced by anticipating the physical and cognitive changes of age. Many employers are aware that such efforts are necessary, but most have not yet addressed them. There is a need for implementation and evaluative research of programs and policies with four dimensions: the work environment, work arrangements and work-life balance, health promotion and disease prevention, and social support. Employers who establish age-friendly workplaces that promote and support the work ability of employees as they age may gain in safety, productivity, competitiveness, and sustainable business practices.

Deindustrialisation and the long term decline in fatal occupational injuries

AIMS

To examine the extent to which deindustrialisation accounts for long term trends in occupational injury risk in the United States.

METHODS

Rates of fatal unintentional occupational injury were computed using data from death certificates and the population census. Trends were estimated using Poisson regression. Standardisation and regression methods were used to adjust for the potential effect of structural change in the labour market.

RESULTS

The fatal occupational injury rate for all industries declined 45% from 1980 to 1996 (RR (rate ratio) 0.55, 95% CI 0.52 to 0.57). Adjustment for structural changes in the workforce shifted the RR to 0.62 (95% CI 0.60 to 0.65). Expanding industries enjoyed more rapid reduction in risk (-3.43% per year, 95% CI -3.62 to -3.24) than those that contracted (-2.65% per year, 95% CI -2.88 to -2.42).

CONCLUSIONS

Deindustrialisation contributed to the decline of fatal occupational injury rates in the United States, but explained only 10-15% of the total change.

Have young workers more injuries than older ones? An international literature review

PROBLEM

Two questions were posed in this global literature review: Do young workers have a higher occupational injury rate? Are the injuries of young workers more often fatal than those of older workers?

METHOD

The studies of nonfatal and fatal injuries were collected based on the following criteria: (a) published in peer-reviewed journals; (b) the young workers were under 25 years of age; (c) the injury rate or fatality rate of young workers and the overall rate was published; and (d) description of the population and the number of injuries was presented.

RESULTS

The majority of 63 nonfatal studies reported showed that young workers had a higher injury rate than older workers. Twenty-nine out of 45 studies on fatal occupational injuries indicated that young workers had a lower fatality rate than older workers. These results are clearer for men than for women.

IMPACT ON INDUSTRY

The results showed that young men were a risk group for occupational injuries. However, the injuries of young workers were reported as less often fatal than those of older workers.

Risk factors for occupational injuries among older workers: an analysis of the health and retirement study

OBJECTIVES

This study examined risk factors for occupational injury among older workers.

METHODS

We analyzed data on 6854 employed nonfarmers from the Health and Retirement Study (HRS), a population-based sample of Americans 51 through 61 years old.

RESULTS

Occupational injuries were associated with the following: the occupations of mechanics and repairers (odds ratio [OR] = 2.27), service personnel (OR = 1.68), and laborers (OR = 2.18); jobs requiring heavy lifting (OR = 2.75); workers' impaired hearing (OR = 1.60) and impaired vision (OR = 1.53); and jobs requiring good vision (OR = 1.43). Self-employment was associated with fewer injuries (OR = 0.47).

CONCLUSIONS

These results emphasize the importance of a good match between job demands and worker capabilities.

Occupational injury deaths among females. The US experience for the decade 1980 to 1989

From 1980 through 1989, females accounted for 44% of the total employed population. Thus, occupational safety and health issues specific to the experience of women merit consideration. Research has demonstrated that the occupational fatality experience of females is not adequately described by the group of all workers. The leading cause of death for all workers is motor vehicle incidents, while the leading cause of occupational injury death of females is homicide. The National Institute for Occupational Safety and Health (NIOSH) has compiled a decade of data on the fatal occupational injury experience of US workers, providing a sufficient number of female cases to allow separate analyses. Over the decade, 3821 females died as a result of injuries sustained at work, with an average annual fatality rate of 0.82/100,000 female workers. Among industries, retail trade and services accounted for nearly half of all occupational injury deaths to females. The detailed occupations with the highest rates of work-related injury death were airplane pilots and navigators, drivers of heavy trucks, construction laborers, and police and detectives. Information on the causes of work-related injury death by occupation is fundamental to the prevention of these deaths. The causes of death in the highest-risk occupations included aircraft crashes, motor vehicle collisions, pedestrians struck by motor vehicles, and homicides by firearms. These data provide a foundation for the prevention of occupational injury deaths among females in the United States.

Age and fatal work-related falls

In the work environment, an increased risk of fatal injury from falls is seen at ages not normally considered to be old. This study examined fatality data from a National Institute for Occupational Safety and Health death certificate database and from Occupational Safety and Health Administration (OSHA) investigations to analyze the relationship of age to fatal work-related falls. For 1980 to 1986, death certificates reported 43,505 fatal work injuries in men, 4179 of which were from falls. Fatality rates from falls showed an increase for older workers beginning with the age group of 45-54, whereas fatal injury rates for other work-related causes did not increase until the age group of 55-64. OSHA investigations of 996 fatal work-related falls in 1984-1986 reported that falls from ladders accounted for 20% of fatal falls in workers aged 55 and over, significantly more than the average of 9% of all falls for workers of all ages. OSHA data also showed that fatal falls among older workers were associated with lower energy of impact, which means that the height of fatal falls tends to decrease with increasing age.

Fatal occupational accidents in Ontario, 1986-1989

We examined 470 fatal occupational accidents in Ontario, 1986-1989, that met eligibility criteria. Homicides and most accidents on public roads were excluded. Information was obtained from coroners' files and records of the provincial Ministry of Labour. Levels of alcohol likely to produce impairment were found in six subjects (2% of the two-thirds of fatalities tested). Cannabis was detected in 3.9% of cases (17% of those tested), but other illegal drugs were not found. Recommendations of coroner's juries showed that organizational factors were considered relevant on many occasions, although language and literacy were rarely mentioned. The incidence rate rose steadily with age. Other data items were examined, although, because of missing information and/or lack of denominator data for many of them, the conclusions that can be drawn are limited. Among these tentative findings was that more fatal accidents occurred in the first half of the shift than in the second half.
