Occupational Infectious Disease Exposures in EMS Personnel

Reports of occupationally transmitted hepatitis B virus (HBV) and human immunodeficiency virus (HIV) prompted the Portland Bureau of Fire Rescue and Emergency Services (PFB) to institute a comprehensive program for handling and tracking on-the-job infectious disease exposures. Data were collected for a 2-year period beginning January 1, 1988, and ending December 31, 1989, utilizing verbal and written exposure reports, prehospital care reports, and PFB statistical information. Two hundred and fifty-six (256) exposures were categorized. The overall incidence of reported exposure was 4.4/1,000 emergency medical service (EMS) calls. Of these exposures, 14 (5.5%) were needle sticks, 15 (5.9%) were eye splashes, 8 (3.1%) were mucous membrane exposures, 38 (14.8%) were exposure to nonintact skin, 120 (46.9%) were exposures to intact skin, and 61 (23.8%) involved respiratory exposure only. The incidence of exposure of nonintact skin or mucous membranes to blood or body fluids and needle sticks was 1.3/1,000 EMS calls. Forty-eight individuals (64% of those incurring needle sticks, or exposure of non-intact skin or mucous membranes to blood or body fluids) were treated and followed for signs of infection. Of this group, 11 individuals (26%) previously vaccinated against hepatitis B demonstrated inadequate HBsAb titers at the time of exposure. Requests for HIV and HBV information on source patients were made for needle sticks or exposure of nonintact skin or mucous membranes to blood or high-risk body fluids. Information on the source patient's HIV status was obtained for 57% of these requests.(ABSTRACT TRUNCATED AT 250 WORDS)
