Prevalence and Antimicrobial Susceptibility of Wound Pathogens in a Tertiary Care Hospital in Kashmir: A Cross-sectional Study.

BACKGROUND

Wound infections significantly impact morbidity, mortality, and healthcare costs globally. The Kashmir Valley's unique geographical and climatic conditions, coupled with resource constraints and antibiotic misuse, complicate managing these infections effectively. This study aimed to identify predominant bacterial pathogens in wound infections at a tertiary care hospital in Kashmir, determine their antibiotic susceptibility profiles, and estimate the prevalence of multidrug-resistant (MDR) strains.

MATERIALS AND METHODS

A prospective cross-sectional study was conducted from January to June 2023 at the Government Medical College, Srinagar. Pus samples from wound infections were aseptically collected and processed following standard microbiological protocols. Antibiotic susceptibility testing utilized the Kirby-Bauer disk diffusion method, adhering to Clinical and Laboratory Standards Institute guidelines. Data were analyzed using IBM SPSS statistics.

RESULTS

Out of 4,378 samples analyzed, bacterial growth was observed in 1,921 samples, representing 43.9% of the total. Among the bacterial isolates, Gram-negative bacilli accounted for 73.5%, with being the most prevalent at 27.9%. Among Gram-positive cocci, predominated, comprising 25.9% of the isolates. Methicillin-resistant exhibited 100% susceptibility to linezolid but low susceptibility to erythromycin (27.0%) and clindamycin (24.0%). demonstrated high susceptibility to tigecycline (97.4%) and amikacin (75.0%), but lower susceptibility to imipenem (45.0%) and piperacillin-tazobactam (57.8%).

CONCLUSION

The substantial wound infection burden and high MDR prevalence in Kashmir necessitate comprehensive antimicrobial stewardship and infection control programs. Regular surveillance, education, and research are crucial to address antibiotic resistance and ensure effective wound infection management in the region.
