High Prevalence of Multi-Drug Resistance and Extended-Spectrum Beta-Lactamase-Producing Among Hospitalized Patients Presumptive for Bacterial Infection at Debre Berhan Comprehensive Specialized Hospital, Ethiopia.

BACKGROUND

Multi-drug resistant (MDR-E), primarily extended-spectrum beta-lactamase producers (ESBLs), have emerged as a major public health concern. This study aimed to determine the prevalence of multi-drug resistance and extended-spectrum beta-lactamase-producing among hospitalized patients presumptive for bacterial infections at Debre Berhan Comprehensive Specialized Hospital, Ethiopia.

METHODS

A hospital-based cross-sectional study was conducted from January to May 2021. A total of 384 hospitalized patients presumptive for bacterial infections were included in the study. Urine, wound, blood, stool, and sputum samples were collected and cultured on MacConkey agar, Cysteine Lactose Electrolyte Deficient medium, and Blood agar. Identification was done using a panel of biochemical tests. The antimicrobial susceptibility test was done by disc diffusion. Screening of ESBL production was done by using cefotaxime and ceftazidime and confirmed by the combination disk method per clinical laboratory standard institute guidelines. Data analysis was performed by Statistical Package for Social Sciences software version 25, and a P-value ≤0.05 was considered as statistically significant.

RESULTS

Out of 384 study participants, a total of 164 were isolated. The overall multi-drug resistance rate (MDR) was 92.1%. The overall prevalence of ESBL-PE was 104 (63.4%). 50 (30.5%) and 24 (14.6%) were the predominant ESBL producers. The highest ESBL producers (13.4%) and (6.1%) were isolated from urine sample. History of antibiotic use for the last three months (P-value=0.01), admission in neonatal intensive care unit (P-value=0.02), history of hospital stays (P-value=0.01), and chronic disease (P-value=0.04) showed statistically significant association with ESBL-PE infection.

CONCLUSION

The prevalence of MDR-E and ESBL-PE was high. Therefore, strong infection prevention and control measures and careful selection of antibiotics are needed in the study area to block the transmission and infection in the healthcare setting.
