A study of patterns and prevention of blood exposures in OR personnel.

The authors conducted a surveillance study of occupational blood exposures in the ORs at six hospitals to identify risk patterns and prevention strategies. For 15 months, trained circulating nurses recorded OR staff members' exposures during all surgical procedures using a modified version of the Exposure Prevention Information Network surveillance system. It was discovered that a high proportion of percutaneous injuries were potentially preventable if safer devices had been used, and the authors estimate that use of blunt suture needles alone could reduce injuries by 30%. Increased use of barrier precautions is indicated to prevent mucocutaneous blood exposures. Health care workers' eyes were identified in the study as being the most vulnerable location for serious blood exposures.
