Prevalence of hospital-acquired infections in the university medical center of Rabat, Morocco

Abstract

Background

The aims of this study were to determine the hospital-acquired infections (HAI) prevalence in all institutions of Rabat University Medical Center, to ascertain risk factors, to describe the pathogens associated with HAI and their susceptibility profile to antibiotics.

Materials and methods

Point-prevalence survey in January 2010 concerning all patients who had been in the hospital for at least 48 hours. At bedside, 27 investigators filled a standardized questionnaire from medical records, temperature charts, radiographs, laboratory reports and by consultation with the ward’s collaborating health professionals. Risk factors were determined using logistic regression.

Results

1195 patients involved, occupancy rate was 51%. The prevalence of HAI was 10.3%. Intensive care units were the most affected wards (34.5%). Urinary tract infection was the most common infected site (35%). Microbiological documentation was available in 61% of HAI. Staphylococcus was the organism most commonly isolated (18.7%) and was methicillin-resistant in 50% of cases. In multivariate analysis, risk factors associated with HAI were advanced age, longer length of hospital stay, presence of comorbidity, invasive devices and use of antibiotic use.

Conclusion

HAI prevalence was high in this study. Future prevention program should focus on patients with longer length of stay, invasive devices, and overprescribing antibiotics.
