Antibiotic sensitivity profile of Klebsiella isolates and it’s impact on clinical outcome

Background: Antimicrobials are the greatest discovery of the twentieth century. To limit the emergence and spread of resistance, antibiotic therapy should be adjusted according to the results of microbiological culture. Klebsiella isolates causes various types of infections and the incidence of antibiotic resistance is also high in Klebsiella infections. So, Authors plan this study to analyze how the results of microbiological cultures influence the antibiotic use in the treatment of Klebsiella infections.Methods: It is a record based observational prospective study which assessed the impact of Klebsiella positive culture results on antibiotic prescribing pattern and its impact on clinical outcome. Patients with empirical antibiotic therapy and Klebsiella positive were included and patients with inadequate data were excluded in this study and the data were recorded. Recorded data were entered and analyzed in Microsoft Office Excel-2013. Unpaired student t-test was used to compare the mean duration of hospital stay using Past software (version 3.20).Results: There were total 400 patients in our study. Amikacin was the most common drug (n=202) used as empirical therapy. Empirical antibiotic therapy was changed in 161(40.25%) patients. Meropenem was the most commonly used definitive drug. Mean duration of hospital stay is less in empirical sensitive antibiotic therapy as compared to empirical resistance antibiotic therapy having p value <0.0001 which shows significant difference between two groups showing better clinical outcome.Conclusion: Initial empirical therapy with broad-spectrum antimicrobials is a treatment strategy for severe Klebsiella infections.
