ABSTRACT

Respiratory tract infections are one of the commonest types of infection affecting both gram positive and negative isolates, an important cause of hospital acquired infections. Antibiotic resistance- a major problem in the ICU, occurs when the bacteria changes it response to the use of medications. An observational cohort study conducted over a period of 6 months in the MICU of a tertiary care hospital in Kerala. Case records were retrospectively reviewed for demographic data, clinical investigations and management. Data analysis was conducted using Microsoft Excel 2010. This study assessed the prevalence of infection, distribution of gender, age, micro-organism based on class and MAR Index patterns. A total of 100 patients were selected based on inclusion and exclusion criteria. The prevalence of infection was found to be 70% and revealed that males (64%) had greater prevalence than females (36%), the age group which showed the highest prevalence was found to be 32% (32) of 71-80 age group, classification based on types, gram negative bacteria (89%) was found to be the most common type of pathogen and gram positive bacteria (11%) were also found. 45% had less than or equal to 0.2 and 55% had greater than 0.2 MAR Index.
