Introduction: Methicillin resistant S. aureus nasal carriers may be acquired the bacteria from community or hospital. Hospital-acquired bacteria are antibiotic resistant and encourage the patient and his (her) family to infection. The aim of this study was to determine the frequency of hospital-acquired methicillin resistant Staphylococcus aureus nasal carrier patients.
Methods: In this cross-sectional research, all patients admitted to hospital were studied and sampling method was random sampling. Sampling from the nose of 1269 patient hospitalized in different parts of Imam Reza hospital in Kermanshah was done. Patients who first nasal culture was negative were enrolled in the study. After (Hospital-acquired) Staphylococcus aureus detection with conventional laboratory tests, their sensitivity to oxacillin and MIC were determined. The data were analyzed by Chi-square and Fisher exact tests.
Results: Results show that 17.5% of the patients (222 from 1269 patients) were carrier of hospital-acquired Staphylococcus aureus. The most frequently detected bacteria were in heart section (66.7%), CCU (54.5%) and infants (46.5%) and lowest detected from urology (0%), gynecology (10.7%) and surgery (12.4%). 7.46% of the total patients were methicillin resistant Staphylococcus aureus nasal carriers and 82 isolates (36.9%) were methicillin resistant. The most frequently detected of these isolates were from ICU (100%), infants (80%) and internal (42.9%) and lowest detected from CCU and heart 16.7%) and pediatric (21.9%) after urology.
Conclusion: With regard to frequency of nasal carrier in hospitals and the risks in conventional drugs resistant infections, control and treatment of carriers seem imperative. In this way, hospitalized patients in the ICU parts, infants and internal should be considered.
