  Data were collected retrospectively from 130 patient's records presented with symptoms of nosocomial infection in MICU of a Tertiary Health Center, Tumkur from August 2012 to May 2013. Descriptive statistics using percentage was calculated.
  
  
  RESULTS
  Incidence of nosocomial infections in MICU patients was 17.7% (23/130). Of which 34.8% (8/130) was urinary tract infection (UTI) being the most frequent; followed by pneumonia 21.7% (5/130), 17.4% (4/130) surgical site infection, 13.0% (3/130) gastroenteritis, 13.0% (3/130) blood stream infection and meningitis.

  CONCLUSIONS
  The most frequent nosocomial infections (urinary, respiratory, and surgical site) were common in geriatric patients in the MICU setting and are associated with the use of invasive device. Large-scale studies are needed to be carried out in Indian population to plan long-term strategies for prevention and management of nosocomial infections.
