Background Emergency service workers (ESW) are known to be at increased risk of mental disorders but population-level and longitudinal data regarding their risk of suicide are lacking. Method Suicide data for 2001–2017 were extracted from the Australian National Coronial Information Service (NCIS) for two occupational groups: ESW (ambulance personnel, fire-fighters and emergency workers, police officers) and individuals employed in all other occupations. Age-standardised suicide rates were calculated and risk of suicide compared using negative binomial regression modelling. Results 13 800 suicide cases were identified among employed adults (20–69 years) over the study period. The age-standardised suicide rate across all ESW was 14.3 per 100 000 (95% CI 11.0–17.7) compared to 9.8 per 100 000 (95% CI 9.6–9.9) for other occupations. Significant occupational differences in the method of suicide were identified (p < 0.001). There was no evidence for increased risk of suicide among ESW compared to other occupations once age, gender and year of death were accounted for (RR = 0.99, 95% CI 0.84–1.17; p = 0.95). In contrast, there was a trend for ambulance personnel to be at elevated risk of suicide (RR = 1.41, 95% CI 1.00–2.00, p = 0.053). Conclusion Whilst age-standardised suicide rates among ESW are higher than other occupations, emergency service work was not independently associated with an increased risk of suicide, with the exception of an observed trend in ambulance personnel. Despite an increased focus on ESW mental health and wellbeing over the last two decades, there was no evidence that rates of suicide among ESW are changing over time.

Objective: To examine the relative risk of suicide among healthcare professionals compared to other occupations and examine changes in suicide rates over time. Methods: Suicide cases were identified using the National Coronial Information System and were included if they were recorded as a death by intentional self-harm between 2001 and 2017 and were by an employed adult aged 20–69 with a known occupation at the time of death. Suicide methods were reported descriptively. Workforce data at the population level was extracted from the Australian Bureau of Statistics 2011 Census. Age-standardised suicide rates per 100,000 person-years for each of the four occupational groups were calculated using direct standardisation and using the Australian Bureau of Statistics population-level data from the 2011 Census. Negative binomial regression was used to estimate suicide risk by healthcare employment status and profession, to investigate differences by sex and to examine trends in suicide rates over time, using rate ratios and 95% confidence intervals. Results: Healthcare professionals were at increased risk of suicide compared to other occupations (rate ratio = 1.30, 95% confidence interval = [1.19, 1.42], p < 0.001), controlling for age, sex and year of death. Nurses and midwives were identified as being at significantly increased risk of suicide (rate ratio = 1.95, 95% confidence interval = [1.73, 2.19], p < 0.001). Suicide rates among female medical practitioners increased substantially over time ( p = 0.01). Conclusion: Health professionals are at significantly increased risk of suicide, though the relative risk of different groups is changing over time. There has been a substantial increase in the risk of suicide among female medical practitioners with rates of suicide in this group more than doubling over the last two decades. Findings highlight the need for targeted suicide prevention initiatives for healthcare professionals.
