Impact of extreme bushfire seasons on rates of occupational injury and disease compensation claims in first responders

Purpose: This study aimed to use workers’ compensation (WC) data to explore the impact of the extreme bushfires on injury/disease claim rates amongst first responders (FR) compared with other occupations and off-seasons. Methods: Data on WC claims for FR (ambulance officers, paramedics, firefighters, police) and other occupations were obtained from WorkSafe Victoria 2005–2022. Negative binomial regression models adjusting for age, gender and number of employed people were used to estimate incident rate ratios of all injury/disease, mental, musculoskeletal and respiratory claims among FR in summer and extreme bushfires compared to off-season/summer and other occupations. Results: There were 120,022 claims in 2005–2022; 54% were musculoskeletal injuries. Claims rates were significantly higher for all injuries/diseases, mental, musculoskeletal and respiratory conditions in FR than other occupations across off-season, summers and extreme bushfires. FR were 1.5–3.9 times more likely to claim for mental health conditions during extreme bushfires than off-season compared with other occupations. Firefighters were at increased risk of all injury/disease and mental and musculoskeletal injury claims during summer and extreme bushfires than off-seasons. Ambulance officers and paramedics had the highest claim rates, particularly in off-seasons, with a higher risk of all injury/disease and mental claims in extreme bushfires than in summers. Respiratory and mental claims were increased amongst police and other occupations during extreme bushfires. Conclusion: Extreme bushfire events were associated with increased mental claims rates in all FR, with the highest in firefighters. Strategies to better prevent and manage injury/disease risk in FR are urgently required, particularly for mental health conditions.
