Prevalence and antimicrobial resistance of health care associated bloodstream infections at a general hospital in Saudi Arabia.

摘要: OBJECTIVES To determine the trend of health care associated blood stream infection (HA-BSI) at Saudi Aramco Medical Services Organization. METHODS This prospective survey was conducted during year 2002-2006. Definitions HA-BSI infections were based on Centers for Disease Control and Prevention categories. RESULTS There a total 1103 distinct episodes with annual average rates 8.5 per 1000 discharges 18 10,000 patient-days. Of all episodes, 38% primary, 47% central line-associated bloodstream (CLABSI), remaining 15% secondary bacteremias. The hospital wide BSI rate increased from 7.8 to 11.9 (p<0.001). Secondary bacteremia remained relatively stable over study period 3/10,000 patient-days (p=0.41). Primary 6.9 10.6 Hospital CLABSI 3.2 6 (p<0.001) 7 11.8 (p=0.039). Coagulase negative staphylococcus leading pathogen (23.7%) followed by Staphylococcus aureus (11.1%) Escherichia coli (11.1%). candida caused 5%, Klebsiella pneumoniae (9%) Pseudomonas aeruginosa (7.3%). CONCLUSIONS The period. However, primary time. staphylococcus, aureus, most frequent microorganisms.
