It is a 4 year accumulation of data, I am not sure why it claimed EMS is the "MOST DANGEROUS" job, but it certainly is dangerous. Which we all knew all along, just now there is data to prove it. The study never said anything about being attacked by a patient causing death(not that I saw) It showed that being struck by a vechicle, or in an Ambulance crash were the most option causes. And that HEMS accounted for a large amount.
This data shows that within this 4 year margin, FF's deaths were lower than EMS within the same 4 year margin.
"Finally a formal study confirms what we knew in our heavy hearts: EMS has far too many line-of-duty deaths and work-related injuries. The data examined from 2003–2007 comes from a series of credible national sources: The Bureau of Labor Statistics, Census of Fatal Occupational Injuries, the National Institute for Occupational Safety and Health and the occupational supplement to the National Electronic Injury Surveillance System.
The researchers discovered a total of 65 EMS fatalities (13 per year). The EMS fatality rate was 7.0 per 100,000 full-time equivalents (FTE) EMS workers with a 95% confidence interval (CI) of 4.7–9.3.
By comparison, the average for all workers is 4.0 and 6.1 for firefighters in the same four-year period......."
One thing that is also important is that Police & Fire have actual formal reporting and tracking of their line of duty deaths, EMS does not. And like this article states, there most likely are deaths related to EMS that were not reported or included in this data.
