Workplace Injury and Mental Health Outcomes.

Importance: Workplace injury is a widespread problem that impacts mental health and quality of life and places a substantial burden on employers and the health care system.

Objective: To determine whether mental disorder rates differ following workplace injury compared with injuries outside the workplace.

Design, Setting, And Participants: This retrospective cohort study assessed individuals hospitalized for an injury requiring surgery between January 1, 2002, and December 31, 2018, with a 2-year follow-up period using population-based administrative data in Manitoba, Canada.

Mental health in public safety personnel with workplace injuries requiring surgery: a longitudinal population-wide administrative data study in Manitoba, Canada.

Objectives: Public safety personnel (PSP) are responsible for ensuring the safety and security of communities, often putting their own lives and well-being at risk by performing dangerous and demanding work. As a result, these workers are particularly vulnerable to workplace-related physical and mental traumatic injuries. Research is needed to understand the mental health of PSP following traumatic physical injury to inform effective prevention programmes and interventions.

Asthma Among Manitoba Workers: Results from the Manitoba Occupational Disease Surveillance System.

Background: This study characterized the risk of new-onset asthma among workers in Manitoba, Canada.

Methods: Accepted time loss claims from the Workers' Compensation Board of Manitoba from 2006 to 2019, containing workers' occupations and industries, were linked with administrative health data from 1996 to 2020. After restricting the cohort to the first claim per person in an occupation and applying age and coverage exclusions, the cohort comprised 142,588 person-occupation combinations.

Carpal tunnel syndrome among Manitoba workers: Results from the Manitoba Occupational Disease Surveillance System.

Background: Carpal tunnel syndrome (CTS) is associated with occupational high-force repetitive tasks and vibration. This project examines the relationship between CTS and work to: (1) identify jobs and industries with increased CTS risk; (2) explore whether there is a sex difference in the risk of CTS after controlling for occupation; and (3) determine whether any observed relationships persist after excluding Workers Compensation Board (WCB) accepted time-loss CTS claims.

Methods: We linked 95.

Acute myocardial infarctions identified in the Manitoba Occupational Disease Surveillance System: A linkage of worker's compensation and provincial health data.

Introduction: The purpose of this study was to identify jobs and industries that may be associated with increased or decreased risk of myocardial infarction.

Methods: We linked provincial health care data with Workers Compensation Board (WCB) of Manitoba claims data to create the Manitoba Occupational Disease Surveillance System (MODSS). Workers were eligible for inclusion in this study if their WCB claim listed an occupation, their claim could be linked to health data, they had an accepted non-acute myocardial infarction (AMI) compensation time loss claim and were free of a recent (<1 year) AMI diagnosis at the start of disease follow-up.

Determining the influence of the Workers Compensation Board of Manitoba's opioid policy on prescription opioid use amongst WCB recipients.

Background: Opioid medications are commonly used by Workers Compensation Board (WCB) claimants following workplace injuries. The purpose of this study is to describe the impact of an opioid management policy on opioid prescriptions amongst a WCB-covered population compared to changes in the use of these medications in the general population of a Canadian province.

Methods: We linked WCB claims data from 2006 to 2016 (13,155 claims, 11,905 individuals) to Manitoba provincial health records and compared opioid use amongst this group to 478,606 individuals aged 18-65.

Do Differences in Work Disability Duration Between Men and Women Vary by Province in Canada?

Purpose Research has shown that there are important sex and gender-based differences in the work disability duration of men and women. This research is often limited to single jurisdictions, using different outcome measures, and therefore has limited generalisability of findings. This study examined if differences between work disability of men and women differed by province and by duration of work disability.

Practice patterns of occupational medicine physicians in Canada.

The objectives of this survey were to identify the practice patterns of Canadian physicians working in the field of occupational medicine and to determine whether the type of certification influences the nature of the work they perform in the field. An Internet-based survey was conducted in September 2015 of members of the Occupational and Environmental Medicine Association of Canada. Eighty-six Canadian-based occupational medicine physicians completed the survey (response rate 36%).

A comparison of opioid use between WCB recipients and other Manitobans for knee, shoulder, back and carpal tunnel release procedures.

Background: This study's objectives were to evaluate whether WCB claimants with conditions requiring certain surgical procedures are more likely to be prescribed outpatient opioids than other Manitobans and whether those prescribed opioids are more likely to still be on opioid medications 6 months post procedure.

Methods: We compared 7,246 WCB claims for a number of surgical procedures to 65,032 similar procedures performed in other Manitobans. Logistic regression was used to explore the association between being a WCB claimant and being prescribed opioids, while controlling for type of surgical procedure and other potential confounders.

The impact of opioid prescription dose and duration during a workers compensation claim, on post-claim continued opioid use: A retrospective population-based study.

Background: Workers Compensation Board (WCB) recipients are a group commonly prescribed opioids.

Methods: We explored factors influencing post-claim opioid dose and duration by linking data from 22,451 claims with the Manitoba Center for Population Health registry.

Results: On average, the WCB paid for 94.

The ALERT scale: an observational study of early prediction of adverse hospital outcome for medical patients.

Objectives: Some medical patients are at greater risk of adverse outcomes than others and may benefit from higher observation hospital units. We constructed and validated a model predicting adverse hospital outcome for patients. Study results may be used to admit patients into planned tiered care units.

Proportion of opioid use due to compensated workers' compensation claims in Manitoba, Canada.

Background: This study identifies the percentage of opioids prescribed for compensated workplace conditions in Manitoba, Canada and whether Workers Compensation Board (WCB) status is associated with higher prescription opioid doses.

Methods: Opioid prescriptions for WCB recipients were linked with databases housed at the Manitoba Center for Health Policy. Duration of continuous opioid prescription and morphine equivalents (ME) per day (ME/D) were calculated for individuals age 18-65.

A population-based analysis of leaving the hospital against medical advice: incidence and associated variables.

Background: Prior studies of patients leaving hospital against medical advice (AMA) have been limited by not being population-based or assessing only one type of patient.

Methods: We used administrative data at the Manitoba Centre for Health Policy to evaluate all adult residents of Manitoba, Canada discharged alive from acute care hospitals between April 1, 1990 and February 28, 2009. We identified the rate of leaving AMA, and used multivariable logistic regression to identify socio-demographic and diagnostic variables associated with leaving AMA.

Rates of readmission and death associated with leaving hospital against medical advice: a population-based study.

Background: Leaving hospital against medical advice may have adverse consequences. Previous studies have been limited by evaluating specific types of patients, small sample sizes and incomplete determination of outcomes. We hypothesized that leaving hospital against medical advice would be associated with increases in subsequent readmission and death.

Behavioral change with influenza vaccination: factors influencing increased uptake of the pandemic H1N1 versus seasonal influenza vaccine in health care personnel.

Background: Many health care personnel (HCP) choose not to get vaccinated against influenza despite recommendations to do so. The pH1N1 epidemic gave a unique opportunity to evaluate the attitudes to influenza vaccination of a group of HCP who routinely choose not to get vaccinated, but accepted the pH1N1 vaccine.

Methods: HCP employed at a tertiary care hospital in Winnipeg, Canada who received the pH1N1 vaccine were invited to participate in an online survey asking about attitudes and experiences regarding seasonal and pH1N1 influenza and vaccination.

Hospitalization in Winnipeg, Canada due to occupational disease: a pilot study.

Background: The objectives of this study were to identify the extent of occupational exposures to hazardous substances amongst male medical inpatients and to determine the extent to which these exposures may have contributed to the development of medical conditions.

Methods: A random sample of 297 male who were admitted from outside the hospital to the medical wards to a large tertiary care hospital, were between age 18-75 and could communicate in English completed an occupational history questionnaire. This information was merged with an inpatient database which contained patient demographics, admission diagnoses, and co-morbidity data.

Predictors of positive tuberculin skin test (TST) results after 2-step TST among health care workers in Manitoba, Canada.

Background: Baseline 2-step tuberculin skin testing (TST) is recommended for health care workers (HCWs) to identify cases of the "boosting phenomenon" (i.e., a negative initial TST result followed by a positive result) and to track the risk of acquiring occupational tuberculosis.

Effect of school age sports on leisure time physical activity in adults: The CORDIS Study.

Purpose: Data evaluating the impact of various types of childhood physical activity on adult leisure time physical activity (LTPA) are inconsistent. The purpose of this study was to evaluate the influence of organized childhood sporting activities on LTPA as an adult in a cohort of industrial workers.

Methods: The frequency of current LTPA, defined as a half hour or more of activity at least once per week, of 3687 industrial workers in the Cardiovascular Occupational Risk Factors in Israel Study (CORDIS) cohort was the outcome variable.

Association of self-reported religiosity and mortality in industrial employees: the CORDIS study.

This study examined the association between self-reported religiosity and mortality in industrial employees, while controlling for workplace and socioeconomic factors. Subjects were 3638 Jewish Israeli males who participated in a 12-year follow-up study. During this period 253 deaths were recorded.
