Burden of gram-positive bacteria from urinary tract infection: A four-year retrospective study in a tertiary health setting in southern Saudi Arabia
Abstract
BACKGROUND: Antibiotic resistance is a worldwide problem causing significant health-related and economic losses. Gram-positive causes of urinary tract infections (UTIs) are usually underestimated or overlooked by physicians.
AIM: To examine the prevalence of antibiotic resistance among major gram-positive bacteria from UTIs in a tertiary care health hospital in southern Saudi Arabia.
METHOD: A cross-sectional retrospective study was done in a tertiary health setting in southern Saudi Arabia between 2019 and 2022, to identify the major gram-positive bacteria and antibiotic resistance. Data were collected from the hospital records and was analyzed using the SPSS statistical package.
RESULTS: The most common gram-positive species were Enterococcus faecalis (44.7%), Staphylococcus aureus (15.1%), and Enterococcus faecium (12.9%), beta-hemolytic streptococci (8.4%), and methicillin-resistant Staphylococcus aureus (MRSA) (1.8%). The 1540 isolates showed an overall susceptibility of 71.0%, compared to a resistance of 29.0%. The most resistance was among Enterococcus faecium (54.5%), Enterococcus gallinarum (42.4%), Enterococcus faecalis (34.3%), and MRSA (27.2%). The most common resistance was to erythromycin (75.7%), followed by cefotaxime (73.9%), tetracycline (70.5%), ciprofloxacin (54.3%), and Synercid (53.6%). The prediction model indicates an increase in the prevalence of resistance in MRSA and, to a lesser extent, with E. faecalis, E. faecium, and beta-hemolytic…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
