  2. Background NIOSH: National Institutes for Occupational Safety and Health1 -Facilitates surveillance and prevention activities among State partners; funds the NH OHSP NH OHSP (Occupational Health Surveillance Program)2 -Collects, analyzes and interprets surveillance data -Addresses the limitations of existing databases and develops new data sources -Identifies priority occupational health and safety conditions in NH -Disseminates data on the magnitude of occupational injuries and illnesses • Centers for Disease Control and Prevention, Workplace safety and health topics, Surveillance, December 28, 2011. Accessed 2/6/13. Available online: http://www.cdc.gov/niosh/topics/surveillance/ • Armenti, K.

  3. Introduction US Work-Related Injuries, 20103 -139.1 million US workers -4.1 million non-fatal injuries (3.9 cases per 100 FTE4) -3.3 million non-fatal, private sector injuries (3.6 cases per 100 FTE) NH Work-Related Injuries -740,000 NH workers (US DOL-Bureau of Labor Statistics) -40,000 NH Workers’ Compensation claims (2011) -Average award was about $350 -Under-reporting is significant 3. Centers for Disease Control and Prevention, Workplace safety and health topics, Traumatic Occupational Injuries, May 9, 2013. Accessed 2/6/13. Available online: http://www.cdc.gov/niosh/injury 4.

  4. NH Trauma Emergency Medical Services Information System (NH TEMSIS) NH TEMSIS5 -Receives data from 81% of NH EMS agencies -Responders are mandated to report work-related injuries -95% of private sector incidents are injuries6 -Data Fields: relative frequency averages Location: where workers are injured Primary Impression: type of injury sustained Mechanism: how the injury occurred Gender: burden of injury among males and females Age: burden of injury in specific age groups • NHTEMSIS, About Us, 2011. Accessed 2/6/13. Available online: http://www.nhtemsis.org/default.cfm?page=about • Bureau of Labor Statistics, News Release, Workplace Injuries and Illnesses- 2011, October 25, 2012. Accessed 2/6/13. Available online: http://www.bls.gov/news.release/pdf/osh.pdf 4

  5. Methods Inclusion Criteria -Must affirm work-relatedness -No duplicate Incident ID numbers -Eligible cases must contain data in all fields -Cases must be of working age, between 16-65 Primary Analysis -Baseline proportions of primary injury characteristics -All data fields, all response options Demographic Analysis -Work-related injuries by Gender -Age-Stratified: 5 Groups 16-25 26-35 36-45 46-55 56-65 Comparative Analysis -Identify TEMSIS subpopulations with increased risk of work-related injury 5

  6. Results: Primary Analysis Total Incidents, 2009-2011 N= 7733 Eligible Work-Related Incidents, 2009-2011 N= 2168 Baseline Primary Injury Characteristics and Proportions 6

  7. Results: Demographics Gender Age-Stratified Cases Relative Frequency Age Groups 7

  8. Results: Location 8

  9. Results: Primary Impression 9

  10. Results: Mechanism of Injury 10

  11. Results: Comparative Analysis Columns: compare the baseline primary injury characteristic proportion to the proportions of that characteristic in each subpopulation. Ex. Industrial Locations: Compared to the baseline, the proportion of industrial injuries was significantly greater for males; there were significantly more traumatic injuries at industrial locations; and there were significantly fewer fall injuries at industrial locations. Rows: show the primary injury characteristic proportions of each subpopulation and highlight significant differences from the baseline. Ex. Male Subpopulation: Compared to the baseline proportions, males have significantly more industrial injuries and traumatic injuries. 11

  12. Comparative Analysis: Gender Burden -Males suffered more industrial work-related Injuries -Males suffered more traumatic work-related Injuries -Females suffered more work-related falls than was expected by their baseline injury proportion; most falls occurred at service/trade locations like bars and restaurants. 12

  13. Comparative Analysis: Age Burden Proportions (%) Age Groups -Workers aged 26-35 suffered more industrial work-related injuries. -Workers aged 46-55 suffered more work-related falls. -Workers aged 56-65 suffered more work-related falls. 13

  14. Conclusions Baseline Proportions: All work-related injuries N=2168 -Males suffer more work-related injuries than females (72.1%) -Workers aged 46-55 are most likely to be injured (25.5%) -Industrial occupational settings have the greatest prevalence of work related injuries (25.2%) -Traumatic injury is the most common primary impression-type (48.6%) -Falls cause the majority of work-related injuries (25.4%) Location: Industrial workplace Injuries n=547 Compared to baseline proportions, industrial workplaces had: -Significantly more injuries in males (+11.6%) -Significantly more injuries among workers aged 26-35 (+4.1%) -Significantly more traumatic injuries (+15.2%) -Significantly fewer fall injuries (-8%) 14

  15. Conclusions Primary Impression: Traumatic work-related injuries n=1053 Compared to baseline proportions, traumatic injuries were: -Significantly higher among males (+8%) -Significantly more prevalent in industrial workplaces (+7.9%) -Significantly higher among workers who suffered a fall injury (+5.5%) Mechanism: Work-related falls n=550 Compared to baseline proportions, work-related falls were: -Significantly lower among males (-5.2%) -Significantly higher among workers aged 46-55 (+6%) and 56-65 (+6.6%) -Significantly more prevalent at service locations than industrial locations (+10.9%) -Caused a significantly greater proportion of traumatic injuries (+10.5%) 15

  16. Conclusions: High-risk Subpopulations -Males aged 26-35 working in Industrial locations could benefit from traumatic Injury prevention -Males and females, age 46-55, working in Industrial locations could benefit from falls prevention -Males and females, age 46-55 in Service locations like restaurants and bars could benefit from falls prevention. 16

  17. Limitations -TEMSIS population is a subset of the study population: it is not representative of the total population suffering work-related injuries; only 81% of EMS agencies reported to TEMSIS; some are captured by Emergency Departments. -Data quality: interpretation and documentation may depend on level of training/experience of EMS personnel. -Event-based reporting: individuals may have more than one incident during the study period. -Recall bias: EMS personnel enter the data retrospectively. 17

  18. Discussion -TEMSIS is a beneficial new data source for Occupational Health Surveillance. -Provides a broad scope of work-related injuries. -What we learn can help us target prevention efforts. -In order to be useful in other states, it is important to require that “work-relatedness” is captured in the data entry process. 18
