INCIDENCE OF NOSOCOMIAL INFECTIONS IN HOSPITALIZED PATIENTS

The term hospital acquired infection or nosocomial infection are applied to infections developing in hospitalized patients. NI are inherent and inseparable dangers of modern therapy, especially for the critically ill patients. Maximum number of NI's is known to be caused by Staphylococcus aureus, Pseudomonas aeruginosa, and various gram negative bacilli- E. coli, Klebsiella and Proteus. Similarly the major site of infections are respiratory tract, urinary tract and surgical site. This study was planned to isolate and characterize the bacteria causing NI and to study the sensitivity behaviour of above bacteria. The antimicrobial sensitivity was done by Kirbey and Bauer method. Twenty urine sample and ten swab samples from the surgical site of the local hospital in Haridwar were collected out of which 2 urine and 1 pus sample were positive while remaining are negative. The present study shows that the incidence of occurrence of NI in hospital was found to be 10%.
