Review of Powered, Safe Patient-Handling Equipment for Emergency Medical Services via an Insurance Safety Intervention Grant Program
Hayden MA , Reichard AA , Lowe BD , Naber SJ , Wurzelbacher SJ . Prehosp Disaster Med 2025 1-9 ![]() BACKGROUND: Powered equipment for patient handling was designed to alleviate Emergency Medical Service (EMS) clinician injuries while lifting patients. This project evaluated the organizational rationale for purchasing powered equipment and the outcomes from equipment use. METHODS: This project analyzed secondary data obtained via an insurance Safety Intervention Grant (SIG) program in Ohio USA. These data were primarily in reports from EMS organizations. Investigators applied a mixed-methods approach, analyzing quantitative data from 297 grants and qualitative data from a sample of 64 grants. Analysts abstracted data related to: work-related injuries or risk of musculoskeletal-disorders (MSD), employee feedback regarding acceptance or rejection, and impact on quality, productivity, staffing, and cost. RESULTS: A total of $16.67 million (2018 adjusted USD) was spent from 2005 through 2018 for powered cots, powered loading systems, powered stair chairs, and non-patient handling equipment (eg, chest compression system, powered roller). Organizations purchased equipment to accommodate staff demographics (height, age, sex) and patient characteristics (weight, impairments). Grantees were fire departments (n = 254) and public (n = 19) and private (n = 24) EMS organizations consisting of career (45%), volunteer (20%), and a combination of career and volunteer (35%) staff. Powered equipment reduced reported musculoskeletal injuries, and organizations reported it improved EMS clinicians' safety. Organization feedback was mostly positive, and no organization indicated outright rejection of the purchased equipment. Analyst-identified design advantages for powered cots included increased patient weight capacity and hydraulic features, but the greater weight of the powered cot was a disadvantage. The locking mechanism to hold the cot during transportation was reported as an advantage, but it was a disadvantage for older cots without a compatibility conversion kit. Around one-half of organizations described a positive impact on quality of care and patient safety resulting from the new equipment. CONCLUSION: Overall, organizations reported improved EMS clinicians' safety but noted that not all safety concerns were addressed by the new equipment. |
Clinical diagnosis groups developed to bridge the ICD-9-CM to ICD-10-CM coding transition and monitor trends in workers’ compensation claims — Ohio, 2011–2018
Meyers AR , Schrader TN , Krieg E , Naber SJ , Tseng CY , Lampl MP , Chin B , Wurzelbacher SJ . J Saf Res 2025 92 408-419 Introduction: This study aimed to develop a set of broad clinical diagnosis (ClinDx) groups relevant to occupational safety and health. The ClinDx groups are necessary for analysis and interpretation of longitudinal health data that include injury and disease codes from the Ninth and Tenth Revision of the International Classification of Disease, Clinical Modification (ICD-9-CM, ICD-10-CM). Methods: Claims data were analyzed for Ohio Bureau of Workers’ Compensation insured employers from 2011 to 2018. We used interrupted time series regression models to estimate level (frequency) and slope (trend) changes to the percentage of each ClinDx group in October 2015. We created ClinDx groups aligned with ICD-10-CM structure and coding principles. Each ClinDx group was counted once per claim (distinct groups). Monthly percentages were calculated based on the injury date. When present, seasonality was assessed separately for each outcome using an autoregressive-moving average model. Results: The final set of ClinDx groups included 57 mutually exclusive and exhaustive groups. The study population included 661,684 claims, with 959,322 distinct ClinDx groups. Among all claims, 96.27% included injury code(s) and 11.77% included disease(s) codes. At the transition to ICD-10-CM, 33 ClinDx groups lacked any statistically significant (P < 0.05) changes between periods. We observed level changes for 17 ClinDx groups and slope changes for nine groups. Eight ClinDx groups had ≥ 20% (+/-) level changes. Conclusion: While the transition to ICD-10-CM is a break in series, about two-thirds of disease groups and half of injury groups were relatively stable across the transition. These findings also underscore the need for characterizing both injury and disease outcomes when analyzing workers’ compensation data. Practical Applications: The 57 ClinDx groups created in this study may be a practical starting point for other occupational epidemiologic analyses that include a mixture of ICD-9-CM and ICD-10-CM data. © 2024 |
Respiratory-related workers’ compensation claims from private employers — Ohio, 2001–2018
Kurth L , Meyers AR , Wurzelbacher SJ , Naber SJ , Cooper C . J Saf Res 2024 90 128-136 Background: Diseases and conditions related to the respiratory system contribute to work-related morbidity, mortality, and disability. Details on the causes and nature of work-related respiratory disease and the specific industries in which they occur are limited. This study identifies respiratory-related claims in the Ohio Bureau of Workers’ Compensation (OHBWC) system and describes claim and worker characteristics to inform public health surveillance. Methods: We developed a list of respiratory-related International Classification of Diseases Clinical Modification (ICD-CM) diagnosis codes and searched over 2 million claims filed between 2001 and 2018 in the OHBWC system for at least one of these codes. The claim characteristics, rates of claims by employer industry classification, and causes of claims from narrative text were determined for these respiratory-related claims. Results: Among the 23,015 respiratory-related claims (5.8 per 10,000 full-time equivalents [FTE]), 54.6% had at least one ICD-CM code for Allergic Reactions and 30.6% had at least one code for Toxic Effects of Substances Chiefly Non-medicinal as to Source. Claim causes from narrative text included Chemical Exposure (30.3%), Activity Suggesting Exposure (24.4%), and Vapors, Gases, Dusts, or Fumes (VGDF) Exposure (19.3%). The highest overall rates of respiratory-related claims among private employers were for the agriculture, forestry & fishing (11.4 per 10,000), public safety (ambulance services) (11.3), and manufacturing (10.7) industry sectors. Conclusions: Respiratory-related claims in the OHBWC system were often acute in nature and included allergic reactions. Narratives from these claims provide insight into the work-related exposures and events causing claims or the disease and symptom factors surrounding claims. © 2024 |
Oil and Gas Extraction industry workers' compensation claims and proposed safety interventions
Alexander BM , Ramirez-Cardenas A , Wurzelbacher SJ , Meyers AR , Naber SJ . J Occup Environ Med 2024 OBJECTIVE: This study analyzed Ohio workers' compensation (WC) data to identify potential prevention strategies for common Oil and Gas Extraction industry claims. METHODS: Claim rates for 2001-2018 were calculated per full-time equivalent employee. Descriptive analyses on free-text descriptions of lost-time (LT) claims (>7 days away from work) identified common characteristics among claims and injured workers. RESULTS: Among 3,134 claims, 860 (27%) were LT. The industry group, Drilling contractors, experienced the highest LT claims rate, while the cost from Servicing contractors was highest. Contact with objects and equipment caused the highest LT claims rate. The most frequent LT occupation was Roustabout and LT work activity was Material Handling. Transportation Incidents caused most fatalities and hospitalizations. Over half of LT claims were from short-tenured workers. CONCLUSIONS: Both proven and innovative approaches are needed to reduce severe WC claims in this industry. |
Occupational injuries and illnesses among law enforcement officers, 2001-2019: Findings from the Ohio Bureau of Workers'Compensation
Tiesman HM , Konda S , Wurzelbacher SJ , Naber SJ , Attwood WR . Am J Ind Med 2023 66 (12) 1079-1089 BACKGROUND: Occupational injuries are common among law enforcement officers (LEOs) and can impact an agency's ability to serve communities. Workers' compensation (WC) data are an underutilized source for occupational injury surveillance in the law enforcement field. METHODS: LEOs WC claims from the Ohio Bureau of Workers' Compensation (OHBWC) from 2001 to 2019 were identified based on manual review of the occupation title and injury description. Worker, employer, incident, and injury characteristics were described by claim type-medical-only (MO) and lost-time (8 or more days away from work). Data are presented using injury claim counts. RESULTS: From 2001 to 2019, 50,793 WC claims were identified among Ohio LEOs. Of these, 68% were MO claims (n = 34,622). WC claims significantly decreased over the 19-year period (p < 0.001). Seventy-five percent of WC claims were from a LEO with more than one claim and of these, 34% were from a LEO with five or more claims during the study period. Male officers and those aged 25-54 years incurred the highest proportion of total claims (87.8% & 91.8%, respectively). Violence (n = 17,247; 34%), falls/slips/trips (n = 9079; 17.9%), and transportation events (n = 7977; 15.7%) were the leading events. Among the 50,793 claims, there were 79,637 unique clinical diagnosis groups. The most common injury diagnoses were sprains (n = 32,796; 41.2%) followed by contusions (n = 13,529; 17%). CONCLUSIONS: Results can guide the development or improvement of workplace injury prevention strategies for LEOs. Efforts should be focused on better understanding and preventing violent injury events and sprains among LEOs, as well as preventing multiple injury events. |
Construction industry workers compensation injury claims due to slips, trips, and falls Ohio, 20102017
Socias-Morales C , Konda S , Bell JL , Wurzelbacher SJ , Naber SJ , Scott Earnest G , Garza EP , Meyers AR , Scharf T . J Saf Res 2023 Problem: Compared to other industries, construction workers have higher risks for serious fall injuries. This study describes the burden and circumstances surrounding injuries related to compensable slip, trip, and fall (STF) claims from private construction industries covered by the Ohio Bureau of Workers Compensation. Methods: STF injury claims in the Ohio construction industry from 20102017 were manually reviewed. Claims were classified as: slips or trips without a fall (STWOF), falls on the same level (FSL), falls to a lower level (FLL), and other. Claim narratives were categorized by work-related risk and contributing factors. Demographic, employer, and injury characteristics were examined by fall type and claim type (medical-only (MO, 07 days away from work, DAFW) or lost-time (LT, 8 DAFW)). Claim rates per 10,000 estimated full-time equivalent employees (FTEs) were calculated. Results: 9,517 Ohio construction industry STF claims occurred during the 8-year period, with an average annual rate of 75 claims per 10,000 FTEs. The rate of STFs decreased by 37% from 2010 to 2017. About half of the claims were FLL (51%), 29% were FSL, 17% were STWOF, and 3% were other. Nearly 40% of all STF claims were LT; mostly among males (96%). The top three contributing factors for STWOF and FSL were: slip/trip hazards, floor irregularities, and ice/snow; and ladders, vehicles, and stairs/steps for FLL. FLL injury rates per 10,000 FTE were highest in these industries: Foundation, Structure, and Building Exterior Contractors (52); Building Finishing Contractors (45); and Residential Building Construction (45). The highest rate of FLL LT claims occurred in the smallest firms, and the FLL rate decreased as construction firm size increased. Discussion and Practical Applications: STF rates declined over time, yet remain common, requiring prevention activities. Safety professionals should focus on contributing factors when developing prevention strategies, especially high-risk subsectors and small firms. 2023 |
Construction industry workers' compensation injury claims due to slips, trips, and falls - Ohio, 2010-2017

Investigating Physical Violence Against Classroom and Other School Personnel Using Ohio Workers' Compensation Data: 2001-2012
Streit JMK , Naber SJ , Pavisic IC , Howald NR . Occup Health Sci 2020 4 43-62 This study uses workers' compensation data to explore the extent, severity, and context of violence-related injuries sustained by classroom (teachers and aides) and other personnel (e.g., administrators, education support specialists, security, custodial and maintenance workers, food workers) in Ohio's K-12 urban public schools. The Ohio Bureau of Workers' Compensation provided access to claims filed by workers from the state's nine urban school districts from January 01, 2001 to December 31, 2012 (N = 19,508). Injury trends were explored with descriptive statistics and logistic regression analyses. Approximately 25% of all claims filed were violence-related. Overall, violence-related injury rates remained relatively stable from the 2001-2002 to the 2011-2012 academic year. However, the odds of victimization for classroom personnel were 1.84 times the odds of victimization for other personnel. For both classroom and other personnel, the most commonly-sustained injuries resulting from a violent event included contusions; sprains to the neck, back, and upper or lower extremities, and open wounds. Most violence-related injuries were sustained during direct contact with students displaying escalated or aggressive behavior, or during efforts to de-escalate third-party violence. Implications of using workers' compensation data to inform workplace violence research and practice are discussed. |
Workers’ compensation injury claims among firefighters in Ohio, 2001–2017
Quinn TD , Marsh SM , Oldham K , Wurzelbacher SJ , Naber SJ . J Safety Res 2023 85 147-156 Background: Firefighters are at high risk for nonfatal and fatal occupational injuries. While some past research has quantified firefighter injuries using various data sources, Ohio workers’ compensation injury claims data largely have not been used. Methods: Public and private firefighter claims, including volunteer and career firefighters, from Ohio's workers’ compensation data for 2001–2017 were identified based on occupational classification codes and manual review of the occupation title and injury description. The task during injury (firefighting, patient care, training, other/unknown, etc.) was manually coded based on the injury description. Injury claim counts and proportions were described across claim type (medical-only or lost-time), worker demographics, task during injury, injury events, and principal diagnoses. Results: 33,069 firefighter claims were identified and included. Most claims were medical-only (66.28%, <8 days away from work) and involved males (93.81%) aged 25-54 years (86.54%). While the task during injury could not be categorized for many narratives (45.96%), the largest percentage that could be categorized occurred during firefighting (20.48%) and patient care (17.60%). The most common injury events were overexertion involving outside sources (31.33%) and struck by objects or equipment (12.68%). The most frequent principal diagnoses were back, lower extremity, and upper extremity sprains (16.02%, 14.46%, and 11.98%, respectively). Conclusions: This study provides a preliminary basis for the development of focused firefighter injury prevention programming and training. Obtaining denominator data, enabling rate calculation, would strengthen the risk characterization. Based on the current data, prevention efforts focusing on the most frequent injury events and diagnoses may be warranted. © 2023 National Safety Council and Elsevier Ltd |

The role of worker age in Ohio Workers' Compensation claims in the landscaping services industry
Alexander BM , Wurzelbacher SJ , Zeiler RJ , Naber SJ , Kaur H , Grosch JW . J Occup Environ Med 2022 64 (9) 766-776 OBJECTIVE: This study employed analysis of workers' compensation (WC) claims in the landscaping services industry to identify occupational factors associated with claims from workers of different ages. METHODS: Private sector claims for 2005-2017 to the Ohio Bureau of Workers' Compensation (OHBWC) and their free-text descriptions were used along with data from the U.S. Census Bureau American Community Survey to examine rates and types of WC claims by worker age. RESULTS: Although the claim rate for younger workers was higher than for older workers overall (593 vs. 261 per 10,000 full-time equivalent employees, p < 0.001), claims from older workers had higher nonzero median cost ($1002 vs. $522, p < 0.001). CONCLUSION: Analysis of WC claim rates shows significant differences between claims in different age groups. These differences can be used to target safety interventions for the greatest impact. |
Reliability and validity of an employer-completed safety hazard and management assessment questionnaire
Moore LL , Wurzelbacher SJ , Chen IC , Lampl MP , Naber SJ . J Safety Res 2022 81 283-296 Introduction: Managing and improving occupational safety and health requires evaluating performance. Organizations are encouraged to use both lagging indicators (such as injury rates and costs) and leading indicators (such as questionnaire-assessed safety hazards and management practices) for this purpose, but the association between types of indicators over time can be complex. Longitudinal data can assist in clarifying these associations and increasing indicator utility. Method: Employer data were used to evaluate the reliability and predictive validity of a safety management questionnaire. Employers’ longitudinal questionnaire responses and workers’ compensation (WC) claims data were analyzed using a marginal model with time-dependent covariates. Multivariable Poisson and linear regression analyses with claim rate and logarithmic cost, respectively, as dependent variables were carried out after adjusting for industry sector and size. Questionnaire data were used to evaluate questionnaire scaling properties and to assess generalizability of results. Results: One safety management scale was associated with a better WC outcome as predicted and two scales were unexpectedly associated with poorer WC claim outcomes. Analyses assisted in interpreting the latter results, suggesting that WC outcomes were a stimulus for change in some cases. Twelve hazards assessed on the questionnaire were associated with poorer WC claim outcomes as predicted. Conclusions: This study extends leading indicator research using longitudinal questionnaire and WC claims data from employers. Analyses provided insight into associations between leading and lagging indicators, emphasizing the importance of both for safety improvement. Safety management questionnaire scales were predictive of WC claim outcomes, although support for hazard assessments as leading indicators was stronger. Practical Applications: This study supports the use of employer-completed hazard assessment questionnaires for targeting and prioritizing improvement efforts. Employer-completed safety management scales may be useful for directing improvement efforts, although the conditions under which they are completed, including submission to insurers, require additional consideration. © 2022 |
The impact of a state-based workers' compensation insurer's risk control services on employer claim frequency and cost rates
Wurzelbacher SJ , Bertke SJ , Lampl MP , Bushnell PT , Robins DC , Naber SJ , Moore LL . J Occup Environ Med 2022 64 (7) 562-572 OBJECTIVE: This study evaluated the impact of a state workers' compensation (WC) insurer's onsite risk control (RC) services on insured employers' WC claim frequency and cost. METHODS: We used two methods to model 2004-2017 claims data from 4,606 employers that received RC visits over time and compare this claims experience to matching employers that did not receive RC services. RESULTS: Relative total WC claim rates increased slightly after RC services, while relative lost-time claims rates either remained similar or decreased and WC cost rates decreased. The impact of RC services on reducing WC costs was cumulative up to the fourth visit but diminished thereafter. CONCLUSIONS: The insurer RC consultation program was effective in reducing WC cost rates for serviced employers. This is consistent with other research conducted on insurer RC services and related regulatory visits. |
Workers compensation claim counts and rates by injury event/exposure among state-insured private employers in Ohio, 2007-2017
Wurzelbacher SJ , Meyers AR , Lampl MP , Bushnell PT , Bertke SJ , Robins DC , Tseng C-Y , Naber SJ . J Safety Res 2021 79 148-167 ![]() Introduction: This study analyzed workers compensation (WC) claims among private employers insured by the Ohio state-based WC carrier to identify high-risk industries by detailed cause of injury. Methods: A machine learning algorithm was used to code each claim by U.S. Bureau of Labor Statistics (BLS) event/exposure. The codes assigned to lost-time (LT) claims with lower algorithm probabilities of accurate classification or those LT claims with high costs were manually reviewed. WC data were linked with the state's unemployment insurance (UI) data to identify the employer's industry and number of employees. BLS data on hours worked per employee were used to estimate full-time equivalents (FTE) and calculate rates of WC claims per 100 FTE. Results: 140,780 LT claims and 633,373 medical-only claims were analyzed. Although counts and rates of LT WC claims declined from 2007 to 2017, the shares of leading LT injury event/exposures remained largely unchanged. LT claims due to Overexertion and Bodily Reaction (33.0%) were most common, followed by Falls, Slips, and Trips (31.4%), Contact with Objects and Equipment (22.5%), Transportation Incidents (7.0%), Exposure to Harmful Substances or Environments (2.8%), Violence and Other Injuries by Persons or Animals (2.5%), and Fires and Explosions (0.4%). These findings are consistent with other reported data. The proportions of injury event/exposures varied by industry, and high-risk industries were identified. Conclusions: Injuries have been reduced, but prevention challenges remain in certain industries. Available evidence on intervention effectiveness was summarized and mapped to the analysis results to demonstrate how the results can guide prevention efforts. Practical Applications: Employers, safety/health practitioners, researchers, WC insurers, and bureaus can use these data and machine learning methods to understand industry differences in the level and mix of risks, as well as industry trends, and to tailor safety, health, and disability prevention services and research. 2021 |
Lessons learned from Ohio workers' compensation claims to mitigate hazards in the landscaping services industry
Alexander BM , Wurzelbacher SJ , Zeiler RJ , Naber SJ . Am J Ind Med 2021 64 (8) 699-713 BACKGROUND: The landscaping services industry is one of the more dangerous in the United States, with higher rates of both fatal and nonfatal injuries than the all-industry average. This study uses claims from the Ohio Bureau of Workers' Compensation (OHBWC) database to identify high rates of occupational injuries and illnesses in this industry in Ohio. The causes of those illnesses and injuries are highlighted to identify common factors. METHODS: The OHBWC database includes injured-worker industry identification, occupation, business size, demographics, diagnoses, and free-text descriptions of injury circumstances. We identified landscaping service industry claims from 2001 to 2017, and describe annual claim counts and rates. RESULTS: Over the 17-year period, 18,037 claims were accepted, with "Struck by object or equipment" and "Overexertion involving outside sources" being the most common events or exposures. Sprains and fractures were the most prevalent of the more serious lost-time (LT) injuries. Free-text descriptions of claims indicate that arborist work and loading/unloading of work vehicles and trailers are particularly hazardous. Younger and shorter-tenured workers were injured most frequently, although the average workers' age was higher for LT claims. The total cost of claims to the OHBWC from the landscaping services industry for 2001-2017 was over $226,000,000. Almost $214,000,000, or 94.4%, was for LT injuries and illnesses, even though LT claims comprise only 18% of total claims. CONCLUSIONS: Targeted improvements in landscaper safety could come from controlling events leading to LT claims. Engineering controls and improved training are strongly recommended to reduce falls, overexertion, and struck-by injuries. |
