How physicians allocate causation: a scenario study with factorial design

Occupational Disease in New York State: An Update

An assessment of occupational disease in New York State was undertaken that partially replicated and expanded earlier work from 1987. Utilizing an expanded conception of occupational disease, the assessment used a variety of data sources and methods to provide estimates of mortality and morbidity of occupational disease; workers exposed to specific workplace hazards; disparities in occupational disease among racial/ethnic groups and gender; costs and distribution of costs of occupational disease; and accessible occupational medical resources. Examples of the pathways work may impact health in some of the major health issues of current import including stress-related health conditions; substance use; and overweight/obesity were included. The report contains recommendations for addressing the problem of occupational disease in New York State and advocates for the convening of a statewide group to develop an occupational disease prevention agenda.

Filing a Workers' Compensation Claim for Low Back Pain and Associated Factors: Analysis of 2015 National Health Interview Survey

OBJECTIVE

The aim of this study was to examine the degree of reporting work-related low back pain (LBP) by workers' compensation (WC) claim filing and associated factors among US workers.

METHODS

We conducted multivariable logistic regression using the 2015 National Health Interview Survey data.

RESULTS

Among 1203 US workers with self-reported work-related LBP diagnosis, only 19.6% filed for WC. Compared with non-Hispanic White workers, Black, Asian, and Hispanic workers were less likely to file for WC. Workers' compensation filing was less frequent among workers in independent work arrangement and who stopped working, changed jobs, or made a change in work and more frequent among workers 45 to 64 years of age and having high LBP frequency.

CONCLUSIONS

Our study findings suggest underreporting of work-related LBP to the WC system is common. Barriers to WC filing should be addressed especially for racial/ethnic minorities and independent workers.

Course participation and the recognition and reporting of occupational ill-health

BACKGROUND

The Foundation Course in Occupational Medicine for community-based physicians was started in Alberta in 2012 and has since been implemented across Canada. As part of the evaluation of the first 4 years, two studies were initiated to assess the impact of the course on assessment of work-relatedness and case-reporting.

AIMS

To determine whether assessment of work-relatedness, intention to report cases and number of cases reported to the Workers' Compensation Board (WCB) changed during/after the course.

METHODS

In study 1, course participants were asked to rate scenarios describing ill-health potentially resulting from work. They rated work-relatedness on a visual analogue scale and recorded whether they would report to the WCB. Assessments were made before the course started, after course completion or both. In study 2, numbers of reports to the WCB were documented for physicians giving consent, both for Foundation Course participants and a comparison group of community-based physicians. Multilevel regression models were fitted to allow for potential confounders and clustering within respondent.

RESULTS

Among 102 physicians completing at least one set of scenario assessments, ratings of work-relatedness (β = 6.5; 95% CI 2.6-10.4) and likelihood of reporting to the WCB (OR = 1.9; 95% CI 1.2-3.1) increased significantly post-course. The mean annual number of cases reported to the WCB increased from 91.8 to 125.7 among the 35 Alberta physicians included in study 2. This change was only significant (P < 0.05) on a one-sided test.

CONCLUSION

The two evaluative studies showed good evidence of changes in perceptions and intentions but only weak evidence of behavioural change.

Annual incidence of non-specific low back pain as an occupational disease attributed to whole-body vibration according to the National Dutch Register 2005-2012

Non-specific low back pain (nLBP) is the second most important reason for sick leave in the Netherlands, and more than 50% of the workers on sick leave attribute these complaints to their work. To stimulate recognition and prevention, an occupational disease (OD) registration-guideline was implemented for the assessment of the work-relatedness of nLBP in the Netherlands in 2005. The aim of this study is to present the annual incidence of nLBP as an OD and specifically for whole-body vibration (WBV) including patient characteristics such as age, sick leave and actions initiated by the occupational physician (OP). The data were retrieved from the National Dutch Register for 2005-2012. Each year about 118 OPs reported 509 cases (SD 139) of nLBP as an OD in a Dutch working population of 7.5 million workers (8% of all annual reported ODs). Less than 1% of these cases were attributed to WBV: 94% were men, 45% were between 51 and 60 years and 35% were on sick leave for more than 2 weeks. Most initiated actions were ergonomic interventions (35%).

PRACTITIONER SUMMARY

The number of notified cases of nLPB as an occupational disease attributed to whole-body vibration is low with less than 1% of all cases in the Netherlands. An explanation is that other work-related risk factors for nLBP such as lifting are more frequently occurring, more visible and have a higher attributable risk than WBV. However, continuing attention for WBV remains warranted given a higher percentage of cases with sick leave of more than 2 weeks.
