The objective was to know the principal risk factors that influence in the development of surgical would infection, and the economical saving achieved with the control of a single variable, that is, right prophylaxis.
A prospective study was carried out at the Traumatology Department of La Paz Hospital.
A total of 5260 patients operated during 1990-1993 are included.
Active epidemiological surveillance was used to check patients ; logistic regression was used in the multivariant analysis.
The principal risk factors found were : immunodeficiency (OR=8.67), incorrect healing (OR=14.42), reoperated patient (patients who needed more than one surgical procedure while they are admitted ; reoperations) (OR=3.57), type of surgery (OR=4.71) and wrong prophylaxis (OR=6.36).
Making constant all the variables except for prophylaxis, we calculated the percentage of infections prevented by a right prophylaxis, and the cost was calculated starting from the number of extra days of infection.
The number of infections prevented during the four years was 310, saving a total of 194 million pesetas (1.5 million dollars), due to right prophylaxis.
We consider of special importance to control this manipulable risk factor, in order to avoid the development of infections.
