Prevalence of MRSA infections in CHC Zagreb, Croatia

Nosocomial infections are the major problem in many hospitals in most countries and the problem is greater as the hospital is biger. Methicillin-resistant Staphylococcus aureus (MRSA) is the common cause of the infections. We analysed the prevalence of MRSA in Clinical Hospital Centre Zagreb, which is a tertiary university hospital with 1675 beds. METHODS: Prevalence of MRSA infections was analysed through the year 2003 on 33636 patients with 261 951 patient-days (pt days) in a part of CHC Zagreb (167 259 pt days in medical wards, 78 012 pt days in surgical wards, 11 147 pt days in surgical intensive care units (ICU) and 5533 pt days in medical and neurological ICU). Specimens for culture were taken in case of clinical infection from blood, catheter tips, wounds, tracheal aspirate, CFS, pleural fluid, ascitic fluide and urine. Isolation, identification and sensitivity testing were perfomed according to standard methods used in clinical microbiology. RESULTS: In medical wards with 67 MRSA patients, prevalence of MRSA infections was 0.4/1000 pt days ; in surgical wards (surgery, neurosurgery, cardiosurgery and urology), with 85 MRSA patients, prevalence of MRSA infections was 1.09/1000 pt days. Prevalence of MRSA infections in ICUs were as follows: surgical 11.4/1000 pt days, neurosurgical 9.00/1000 pt days, cardiosurgical 4.33/1000 pt days, urological 1.24/1000 pt days, medical 6.14/1000 pt days and neurological 3.07/1000 pt days. MRSA infections was mostly detected in blood (59%) and wounds (44.5%).

MRSA infections was mostly detected in blood (59%) and wounds (44.5%). CONCLUSION: The results urged the implementation of strict infection control policy in our hospital ; are usefull for comparison of the prevalence rate of infection in other hospitals and will be usefull for the next year results comparison in our hopsital.
