Analysis of antibacterial drug use and bacterial resistance in psychiatric hospital in the epidemic
Abstract
Analyze the use of antibacterial drugs and bacterial resistance in psychiatric hospital during the epidemic. Using the hospital information system and the National Antibacterial Drug Clinical Application Monitoring Network, we retrospectively collected data on the use of antibacterial drugs and bacterial resistance in psychiatric hospitals during the 2022 epidemic. During the 2022 epidemic, our hospital had an antibiotic use rate of 5.00%, a usage intensity of 3.07, a combined medication rate of 11.11%, a cumulative DDDs of 12,039.04, and antibiotic costs accounting for 3.95% of total drug costs. These are much lower than the levels in Jiangsu Province and nationwide. However, the rate of microbiological submission for antibacterial drug use was 77.78%, higher than that of Jiangsu Province and nationwide. The main antibiotics used in our hospital were third-generation cephalosporins, penicillins, and quinolone antibiotics, with the most commonly used being cefodizime, amoxicillin, and piperacillin-tazobactam. The results showed that Gram-negative bacteria mainly exhibited resistance to penicillins, cephalosporins, and quinolones, especially ampicillin, amoxicillin-clavulanic acid, ceftazidime, ceftriaxone, amikacin, and ciprofloxacin. Gram-positive bacteria mainly resisted penicillins, macrolides, and quinolones, especially penicillin, benzylpenicillin, erythromycin, levofloxacin, and ciprofloxacin. This study reveals a complex relationship between the rational use of…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence.
