ObjectiveWe performed a prospective analysis at our center to find out the most common organisms causing bacterial infections to establish pattern of antibiotic resistance, in order to combat febrile neutropenia effectively in the terms of outcome as well as cost.MethodsA hospital based observational study was conducted at National Institute of Blood Diseases and bone marrow transplantation from January 2017 to December 2017. Patients presented with absolute neutrophil count (ANC) of less than 500/ml were enrolled. Data were analyzed by SPSS version 21.0. P value of <0.05 was considered statistically significant.ResultsIn this study, a total of 242 patients from various hematological disorders were enrolled and 403 bacterial isolates were obtained. The most frequent isolated gram-negative organisms were Escherichia coli, followed by Klebsiella pneumoniae and the most prevalent gram-positive organisms were staphylococcus aureus and Enterococcus species. The antimicrobial susceptibility testing revealed that most of the Staphylococcus aureus isolates were highly resistant to methicillin (p=0.002), whereas Enterococcus species were resistant to vancomycin (p=0.000).ConclusionThe choice of empirical antibiotic regimen should be based on local spectrum of bacteria and their regional susceptibility pattern to improve the survival and minimize hospital stay of patients.Copyright: © Pakistan Journal of Medical Sciences.
