Estimation of the Cumulative Incidence of Hospital-Acquired Bacteremia From Prevalence Data: A Formula

  • Houssein Gbaguidi Haore (a1), Arno Muller (a1), Daniel Talon (a1) and Xavier Bertrand (a1)


We evaluated the validity of the formula of Rhame and Sudderth to estimate the cumulative incidence of nosocomial bacteremia from prevalence studies. The observed cumulative incidence was threefold higher than the calculated cumulative incidence. We do not recommend converting prevalence into incidence data for nosocomial bloodstream infections.
