Benefit of a single preoperative dose of antibiotics in a sub-saharan district hospital: minimal input, massive impact.

OBJECTIVE

To evaluate the impact of a single-shot preoperative antimicrobial prophylaxis (AMP) to reduce the rate of Surgical Site Infections (SSIs) in a rural sub-Saharan hospital.

SUMMARY BACKGROUND DATA

We analyzed the incidence of SSIs in a rural Tanzanian hospital with very limited resources and found that AMP was administered after incision in 88% without covering the expected pathogens. Inadequacy and mistiming of AMP proved to be major risk factors for SSI in this study. Subsequently, 21.6% of patients developed an SSI after clean or clean-contaminated surgery, with 60% of detected pathogens being resistant to the administered antibiotics. In developed countries, preoperative single shot AMP is widely used and effective in the prevention of SSI.

METHODS

Implementation and monitoring of guidelines for routine and adequate single shot AMP within 2 hours prior to incision in every clean and clean-contaminated intervention.

RESULTS

In the preintervention group, 527 patients qualified for routine AMP that was administered in 88% of patients after incision and did not cover the expected pathogens to a large extent.114 patients (21.6%) developed an SSI, with 60% of detected pathogens being resistant to the administered antibiotics. After implementation of the guidelines, the incidence of SSIs significantly decreased from 21.6% to 4% (11/276).

CONCLUSIONS

The implementation of a single shot AMP dramatically decreased the rate of SSI in a hospital with very limited resources. Such guidelines, developed by industrialized countries, are even more effective in non-industrialized countries.
