accquired infections are rising alarmingly in health care sectors all over the
world including India. 1

Throughout
the world multi drug resistant nosocomial infections are the leading cause of
deaths,morbidity, increase length of hospital stay and cost of health care
amongst hospitalized patients. 1

Hospital
accquired infection is a localised or systemic condition resulting from an
adverse reaction to the presence of an infectious agents or its toxins that was
not present or incubating at the time of admission to the hospital i.e; 48hrs  1

The
incidence of nosocomial infections is about 6-15% in the developed countries
where as in India it ranges from 4-48%,one in four patients admitted to
hospital acquire nosocomial infection(1)

Critically
ill ICU patients are most vulnerable for developing these infections

ICU
infections contributes to 20-25%of all nosocomial
infections in a hospital 2

Factors
like increasing use of invasive devices, immunosupressive drugs,irrational use
of antibiotics like their overuse and missuse due to incorrect diagnosis,irrational
and counterfeit antibiotic market combinations,irregular consumption due to
either wrong prescription or poor compliance leads to widw spread drug
resistance among hospital accquired organisms 2,3,4

Causative
organisms may be present o the skin ,nose ,mouth ,vagina, of the patient or
they may be acquired from health care personnel,visitors,hospital equipment
medical devices or the health care environment 

Most
common organisms are pseudomonas species, acinetobacter.spp, S.aureus, MRSA,
enterobactriacea,candida species Mode of transmission is usually by cross
infectionvia unclean hands of hospital personnel

As Sepsis, the second leading cause
of death in non-coronary ICUs, has a mortality rate of up to 45% (5) and ICU patients are more prone to infections its
imperative on the part of physician to initiate empirical treatment based of
the prevalence of pathogens and their susceptibility to antibiotics to ensure
unnecessary use of antibiotics.

Not many studies are available  in
Indian context and emerging antibiotic resistance is makes newer studies
essential to acknowledge the ongoing pattern of antibiotic sensitivity of the
organisms and early institution of antibiotics. My study aims are identifying
pattern of antibiotic sensitivity of the organisms isolated from ICU in BMJH
