Nosocomial infections are of serious problems in hospital. In addition, they are imposed heavy costs on hospitals, causing increased hospitalization time, increased morbidity and mortality. In this study, we aimed to determine the epidemiological status of nosocomial infections in the Medical Ward of a tertiary care hospital.
The patients admitted in the Department of Medicine were included in this study.
The present study has been done on 80 patients of Medicine Wards (MW) including Medical Intensive Care Unit (MICU) of CSSMU, Lucknow. Among them, 65 (81.3%) were from Medical Ward and 15 (18.7%) were from MICU. This study was conducted between January to June, 2011. The average patient’s stay in both MW and MICU was 13.56 days. All the 80 patients were clinically examined and only 18 patients were selected for the study of nosocomial infection on clinical grounds. A total of 42 different types of specimens were collected from 18 nosocomially infective patients. In 5 specimens, there was no yield of any bacterial organism. The predominant bacterial isolates both in MW and MICU were Escherichia coli (40.5%) followed by Staphylococcus aureus (18.9%), Acinetobacter spp (13.5%), Pseudomonos aeruginosa (10.8% ), Enterococcus faecalis (8.1%) and Klebsiella pneumoniae (8.1%).
Bacterial isolates in MW and MICU were similar meaning thereby that it is auto infection. Nosocomial infection was more common in patients who stayed for longer period in hospital. Escherichia coli and Staphylococcus aureus are predominant to cause nosocomial infection.
