Prospective Evaluation and Mortality Outcome of Nosocomial Infections in Medical Intensive Care Unit at Tertiary Care Teaching Centre in Mumbai

Rakesh Bhadade

Background
Hospital acquired infections are a worldwide phenomenon and infection rates in ICU’s have been documented to be ranging from 12% to 45%.

Methods and material
To study epidemiology of nosocomial infections and it’s clinical outcome.

Study design and setting
It is a prospective observational study; carried out in the Medical intensive care unit (MICU) of a tertiary care teaching hospital.

Results and conclusion
205 patients developed nosocomial infection. The commonest nosocomial infections developing in MICU were Ventilator Associated Pneumonia (VAP); hospital acquired pneumonia followed by urinary tract infection. 94.1% isolates were Gram-negative and Gram-positive contributing to 2.5%, of which most common organisms isolated were Klebsiella, Acinetobacter and E. coli. 93.4% of blood stream infections were associated with intravenous lines, 68.1% of pneumonia with intubation, 91.7% of UTIs were associated with urinary catheter. As number of risk factors increase, like duration of mechanical ventilation, prolonged ICU stay (60.0%), increasing age, and number of organs failed, mortality increased significantly. Sensitivity of E. coli isolates to carbapenams, polymyxin was 100%. Klebsiella and Acinetobacter showed a maximum sensitivity to carbepenem, polymyxin followed by piperacillin-tazobactum. 75.1% of patients with nosocomial infections improved and mortality in current study was 30.3%.
