Hospital Acquired Infection
Hospital acquired infections (nosocomial infection) are infections that develop within a hospital or are produced by microorganism acquired during hospitalization. HAI’s are common in intensive care units (ICU’s). The incidence and prevalence of nosocomial infection in ICUs is much greater than in the general in-patient population of hospital. The rates and types of hospital acquired infection, the distribution of microorganism that cause the infection and the pattern of antimicrobial resistance vary across geographic regions in different hospitals also in different ICUs of the same hospital. Nosocomial infections affect patient morbidity and mortality. Health care works especially those with poor hand hygiene …show more content…
aureus), Acinetobacter calcoaceticus-baumannii complex, Pseudomonas aeruginosa, klebsiella pneumonia , Escherichia coli ( E.coli), Enterococcus, Burkholderia, Enterobacter, Proteus, coagulase negative staphylococci ( S.epidermidis, S. saprophytic). Although most of gram–ve bacilli can’t remain in dry surfaces and sensitive to common disinfectant, Acinetobacter calcoaceticus-baumannii complex, Pseudomonas aeruginosa and Klebsiella pneumonia considered as the most common bacterial pathogens of hospital acquired infection.
The most common types of nosocomial infections are pneumonia (ventilator associated pneumonia), bloodstream infection, urinary tract infection and surgical site infection. The ventilator associated pneumonia and bloodstream infections are commonly caused by Acinetobacter calcoaceticus-baumannii complex while urinary tract infection commonly caused by Pseudomonas aeruginosa and surgical site infection commonly due to …show more content…
diabetes mellitus, malignancy, chronic kidney disease), tracheostomy, pre-ICU antibiotic administration, but they found that prolonged mechanical ventilation, central venous catheter and pre-antibiotic administration are more scientifically associated with ICU-acquired infection. In addition, there are other factors affect the infections rate includes types of ICU, quality of care, severity of illness, poor infection control, patient selection and discharge criteria of the ICU. In general, we can say patients in ICUs are at highest risk for hospital acquired infection because of the invasive medical procedures during their hospitalization.
More than 90% of patients in the ICU received antibiotics. The most common antimicrobial used were β lactam- β lactamase inhibitor, aminoglycoside, fluoroquinolones and carbapenems. Staphylococci were methicillin-resistant (MRSA), Enterococcus strains were vancomycin-resistant, Acinetobacter calcoaceticus-baumannii complex, Pseudomonas aeruginosa and Klebsiella pneumonia were
