Why do people assault those who are trying to help them (or their family members)? Alcohol, drugs, and dementia are among the causes, and the result is that health care workers and social workers face a high risk of on-the-job injury. The Edmonton Journal reports that nearly 20 percent of the Workers Compensation Board of Alberta claims are for violence aimed at health care workers (thanks to Tasha for the link). At The Doctor’s Office online WSJ column, Dr. Benjamin Brewer reports that a study at a large Florida hospital found 74% of the nurses reported being physically assaulted during the past year.

Meanwhile, Philly.com has the story of a social worker who went to a home to check on a report of an unsupervised toddler and was attacked by the child’s inebriated mother – and then had a hard time finding someone to call the police for her because the first three neighbors she begged for help didn’t want to get involved. Earlier this year, Kentucky passed a law requiring new safety measures for social workers after social services aide Boni Frederick was fatally beaten and stabbed while on the job (Occupational Hazards has a summary).
