Summary
Surgeons face a significant cumulative risk of human immunodeficiency virus (HIV) infection, estimated between 1 in 100 to 1 in 5. Reducing percutaneous injuries through improved protection and surgical techniques is crucial for surgeon safety.
Area of Science:
- Occupational Health
- Epidemiology
- Infectious Disease Prevention
Background:
- Healthcare professionals, particularly surgeons, are at risk of percutaneous injuries during procedures.
- Human immunodeficiency virus (HIV) transmission is a concern following occupational exposure.
Purpose of the Study:
- To estimate the cumulative risk of HIV infection for surgeons based on injury rates and HIV prevalence.
- To highlight the importance of risk mitigation strategies in surgical settings.
Main Methods:
- Utilized a probabilistic model to calculate cumulative HIV infection risk.
- Incorporated data on the probability of HIV transmission after percutaneous inoculation.
- Factored in the frequency of percutaneous injuries in surgical practice.
- Assumed average surgeon caseloads and career length for risk projection.
Main Results:
- The probability of HIV infection after a single percutaneous injury is estimated at 1 in 250.
- Percutaneous injury frequency in surgery ranges from 1 in 40 to 1 in 20 cases.
- Cumulative surgeon risk for HIV infection varies from 1 in 100 to 1 in 5, depending on HIV prevalence (1 in 100 to 1 in 10).
Conclusions:
- Surgeons face a substantial cumulative risk of HIV infection.
- There is a critical need to reduce the incidence of percutaneous injuries in surgery.
- Enhanced barrier protection and modifications in surgical techniques are essential to mitigate occupational HIV risk.
