Summary

Operating room personnel face infection risks from blood contact. Most blood contacts, particularly among surgeons, are preventable with enhanced barrier precautions and improved surgical gloves.

Area of Science:

  • Healthcare-associated infections
  • Occupational safety in surgery
  • Infection control in operating rooms

Background:

  • Operating room (OR) personnel are susceptible to blood-borne pathogen transmission via blood contact.
  • Understanding the frequency and nature of these exposures is crucial for risk mitigation.

Purpose of the Study:

  • To delineate the frequency and types of blood contact experienced by OR personnel.
  • To identify specific risk factors associated with these blood exposures.
  • To assess the potential for prevention through enhanced barrier precautions.

Main Methods:

  • Trained observers prospectively monitored 206 operations across six surgical services.
  • Data collected included the number and type of blood contacts per person-procedure.

  • Statistical analysis identified risk factors and potential preventive measures.

    • Main Results:

    • Blood contact occurred in 30.1% of operations, with 5.3% of person-procedures involving 147 blood contacts.
    • Surgeons experienced the highest rate of blood contact (18.6 per 100 person-procedures).
    • Key risk factors for surgeons included emergency procedures, >250mL blood loss, and OR duration >1 hour. Many exposures were preventable with better barriers.

    Conclusions:

    • A significant proportion of blood contacts in the OR are preventable.
    • Enhanced barrier precautions (e.g., face shields, resistant gowns) and improved glove technology are indicated.
    • Reevaluation of surgical techniques may further reduce occupational exposure risks.
