  1. Risk of hepatitis C virus transmission to surgeons and nurses from infected patients : model-based estimates in France.

    Article - En anglais

    Background/Aim 

    The aim of this study was to estimate the annual number of cases of hepatitis C virus transmission from infected patients to uninfected surgeons or nurses due to percutaneous injury during invasive procedures Methods :

    • The risk of transmission was estimated using a model involving three probabilities : A, that a health care worker sustains at least one percutaneous injury during a procedure ;

    • B, that 1 to 10% of patients are seropositive for hepatitis C virus ;

    • and C, that infection by this virus is transmitted to the Health Care Worker after such exposure.

    Probability A was estimated from the results of 2 French multicentric prospective trials.

    Probability C was estimated from the results of 9 international prospective studies.

    A ten-fold decreased risk was assumed for surgeons who wear gloves and use solid-bore suture needles.

    Results 

    During a single procedure, the estimated probability of hepatitis C virus transmission from an infected patient to an uninfected surgeon ranged from 4.2x10-5% to 4.2x10-4%, and from 2.98x10-6% to 2.98x10-5% to an uninfected nurse.

    For surgeons, the estimated annual cumulative risk of occupational infection ranged from 0.01% to 0.1% (1 in 10000 to 1 in 1000), and for nurses from 0.0054% to 0.054% (1 in 18700 to 1 in 1900).

    Conclusions 

    Between 2 and 21 surgeons out of a total 20000 are estimated to acquire occupationally-related hepatitis C virus infection, and between 16 and 167 nurses out of a total 300 000. (...)
