Nursing facilities are the most dangerous workplace in Maine and the fifth most dangerous workplace in the U.S., according to a new study from an insurance company.

The research, conducted by Allsup, a provider of Social Security Disability Insurance representation, looked at serious workplace injuries that resulted in an employee having a “job transfer or restriction,” or an employee being prevented from the typical functions of his/her job or from working a fully scheduled day.

Findings were separated into private and government-run industries. Maine had the most worker injuries in both private and state-run nursing facilities, with an average of five injuries per 100 workers. Iowa had the most injuries for sites that were run by the state, and Indiana had the most injuries in privately owned facilities.

Nursing home employees are at risk for injury when moving residents. The Occupational Safety and Health Administration launched a campaign in July to reduce the number of musculoskeletal injuries among long-term care workers. Providers also are being encouraged by the American Nurses Association to reduce manual handling of residents.

The data comes from the 2011 employer survey, “Nonfatal Occupational Injuries and Illnesses Requiring Days Away From Work,” by the U.S. Bureau of Labor Statistics.

Forty-one states and the District of Columbia were included in the report.
