Abstract

Escherichia coli (E. coli) is a critical-priority group of MDR bacteria and its spread can occur in hospital inpatient settings. Several studies showed that antibiotics consumption for inpatients can cause E. coli resistance to other antibiotics called cross-resistance. The aim of this study to determine the cross-resistance in E. coli to antibiotics in the inpatient installation of the regional general hospital "X" in Bali, Indonesia by analyzing the relationship between the antibiotic consumption and the percentage of antibiotic resistance of E. coli. This research is an ecological study with the independent variable is the antibiotics consumption defined as defined daily doses/100 bed-days and the dependent variable is the percentage of E. coli resistance during 2017-2020. The correlation between the level of antibiotic consumption and the percentage of E. coli resistance to antibiotics was analyzed using the Pearson correlation tests. The results showed that the consumption of tetracycline had a significant correlation with increased resistance of E. coli to meropenem and piperacillin-tazobactam (r=0.8-1.0; p<0.05). This showed that there is cross-resistance in E. coli. This incident is associated with selective pressure, horizontal and vertical gene transfer in E. coli. The consumption of tetracycline, apart from inducing the production of the tet gene which is the cause of resistance to tetracycline, can also induce the production of resistance genes to broad-spectrum beta-lactam antibiotics such as piperacillin-tazobactam and meropenem.

Abstract

Antibiotic resistance is a growing global health threat, partly driven by high antibiotic consumption. The World Health Organization (WHO) has identified critical-priority bacteria, including Escherichia coli and Klebsiella pneumoniae, due to their increasing resistance to multiple antibiotics. This study aimed to evaluate the correlation between antibiotic consumption and resistance rates in Escherichia coli and Klebsiella pneumoniae. This ecological study was conducted at a Regional Hospital in Indonesia based on retrospective inpatient data from January 2019 to December 2023. The population in this study is all data on systemic antibiotic consumption based on the J01 category of the Anatomical Therapeutic Chemical/Defined Daily Dose (ATC/DDD) classification system and antibiogram from inpatient databases. Pearson and Spearman’s rank correlation analyses were performed to examine the associations between systemic antibiotic consumption levels and the percentage of Escherichia coli and Klebsiella pneumoniae resistance to other antibiotics. The most frequently used antibiotics were cefixime (305.664 DDD/100 bed-days), levofloxacin (139.552 DDD/100 bed-days), and ceftriaxone (109.805 DDD/100 bed-days). A strong and statistically significant correlation was observed between doxycycline consumption and Escherichia coli resistance to meropenem (r=0.894; p=0.041). Moreover, consumption levels of cefazolin, ceftazidime, cefepime, and ciprofloxacin were correlated with Escherichia coli resistance to ceftriaxone (p<0.05), while cefoperazone use demonstrated a very strong and statistically significant correlation with Escherichia coli resistance to ampicillin-sulbactam (r=0.952; p=0.012). Conversely, no significant correlation was found between antibiotic consumption and resistance in Klebsiella pneumoniae, suggesting that alternative factors such as intrinsic resistance mechanisms, mobile genetic elements, and environmental reservoirs may influence resistance development.

Abstract

Pseudomonas aeruginosa, Acinetobacter baumannii, Escherichia coli, and Klebsiella pneumoniae are the most critical groups of multi-drug resistant (MDR) bacteria that cause a threat in hospitals. This study identified the trend of antibiotic consumption, antibiotic resistance pattern, and the relationship between antibiotic consumption and antibiotic resistance in a critical group of bacteria in a general regional hospital. This ecological study was based on retrospective data from inpatient databases in a general regional hospital over three years (2017-2019). The trend for annual antibiotic consumption over 2017-2019 was defined as defined daily doses/100 bed-days. The relationship between total antibiotic consumption and the percentage of antibiotic resistance among four isolated critical bacteria was explored in time series analysis and linear regression. The most frequently used antibiotic was ampicillin (220.33 DDD/100 bed-days), ciprofloxacin (126.86 DDD/100 bed-days), and ampicillin-sulbactam (126.34 DDD/100 bed-days). There was a significant relationship between antibiotic consumption (ampicillin, ampicillin-sulbactam, ceftazidime, gentamicin, amikacin, and ciprofloxacin) in DDD/100 bed-days and antibiotic resistance in E. coli, K. pneumoniae, and P. aeruginosa (p<0.05) but not statically significant in A. baumannii (p=0.062). The annual usage fluctuated or remained stable, with no statistically significant trends change. The relationship between antibiotic consumption and antibiotic resistance was significant in three out of four critical groups of bacteria.
