Bacteriological Study on Chronic Suppurative Otitis Media in a tertiary care hospital

Abstract

Chronic suppurative otitis media (CSOM) is a common hearing condition that can lead to a variety of consequences if not treated effectively. As a result, the study's goal is to identify the bacterial isolates responsible for CSOM and investigate their antimicrobial susceptibility pattern. The research was conducted over a seventeen-month period in a north coastal region of Andhra Pradesh, from December 2019 to May 2021. The study comprised 150 CSOM patients with unilateral or bilateral discharge who attended the ENT Out Patient Department at GEMS Hospital, Ragolu, Srikakulam. Swabs were collected and immediately transported to the microbiology laboratory to be processed. Standard procedures were used to identify bacterial isolates, and antibiotic susceptibility testing was performed. The most common organism isolated was Staphylococcus aureus, followed by Pseudomonas sp., Proteus spp., Klebsiella pneumoniae, and Escherichia coli. The current investigation aided in determining the bacteriological profile of CSOM patients. Because of the evolution of resistant organisms, empirical therapy may not be beneficial in all situations. As a result, it is recommended that an antibiogram be performed prior to beginning medication.
