Prevalence of nosocomial wound infection among postoperative patients and antibiotics patterns at teaching hospital in Sudan.

BACKGROUND

Postoperative nosocomial infections remain a major problem in health care facilities, resulting in extended length of stay, substantial morbidity and mortality, high excess of cost, and less frequent cause of death in the surgical patient.

AIMS

To determine the prevalence of aerobic nosocomial pathogens among patients with postoperative wound infections at Gadarif state which located in Eastern part of Sudan.

MATERIALS AND METHODS

109 wound swabs were collected from patients who had developed postoperative wound infection. Conventional technique for isolation of bacteria was applied with analytical profile index (API system) for identification to confirm primary and secondary isolates. Antibiotics susceptibility was applied for all isolated bacteria.

RESULTS

Aerobic bacterial isolates were S. aureus (n=55, 55.0%), P. mirabilis (n=35, 35.0%), E. coli (n=5, 5.0%), Ps. aeruginosa (n=3, 3.0%), and Pr. vulgaris (n=2, 2.0%). The prevalence rate of hospital acquired infection were 25.23%

CONCLUSION

The highest prevalence rate of nosocomial postoperative wound infection, in Sudan was due to poor antibiotic selection, for prophylaxis during and after surgery and increased level of contamination in most part of the hospital.
