Antimicrobial Drug Utilization and Resistance Trends in Septicemia Patients: A Comprehensive Study at a Tertiary Care Hospital

Background: Septicemia is still among the leading causes of morbidity and mortality worldwide, especially among patients in the intensive care unit. The right use of antimicrobial agents is central to the successful management of septicemia, but increasing incidences of antimicrobial resistance are a big challenge. Objective: This study aimed to quantify the antimicrobial usage, resistant organisms, and clinical performance in septicemia patients in a tertiary healthcare facility in Bangladesh. Methods: A prospective observational study was done in the Department of Medicine, Community Based Medical College Hospital, over a period of 16 months. One hundred and ten participants with septicemia and admitted to the ICU were recruited. Demographic data, antimicrobial consumption, microbiological results, and clinical outcomes were gathered and examined. Results: Most of the patients were male (54.5%) and within the age group of 31–40 years. Cephalosporins were the most common first-line antimicrobials (13.3%), while macrolides (12.3%) and carbapenems (11.7%) were at the second and third rank, respectively. There were frequent alterations in antimicrobial therapy; in 28 percent of cases, ceftriaxone was replaced by levofloxacin. Patients with resistant infections had the advantage of a longer hospital and ICU stay of at least 1 week (p<0.01). 16% in patients with resistant infections. Conclusion: The topics discussed in this study include the issues arising from septicemia management due to antimicrobial resistance, the requirement of broad-spectrum empiric therapy, often changing antimicrobial regimens, and overall poor outcomes for such resistant infections. Overall, the present results highlight the need for strict adherence to principles of antimicrobial stewardship, local resistance pattern monitoring, and the creation of novel therapeutic interventions.
