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.

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.
