More nurses die from deliberate drug overdose than any other health care professionals, according to a landmark new study. Researchers examined more than 400 drug-related deaths of healthcare workers between 2003 and 2013. It included medical practitioners, paramedics, nurses, dentists, psychologists, pharmacists and vets. The highest number of deaths was amongst nurses — 62 per cent of the deaths — followed by medical practitioners, at 18 per cent. Most of the nurses were women, and the doctors male.
