Background: In the era of COVID-19 pandemic, there is an upsurge of healthcare-associated infections (HAI) in COVID intensive care units (ICUs), which can be reduced by following proper hand hygiene (HH) practice. Performing HH auditing in COVID ICU and providing timely feedback to the stake holders is crucial to reduce HAIs. Methods: From November 2020-April 2021, HH audit was conducted in COVID ICUs. HH complete adherence rate (HHCAR), HH partial adherence rate (HHPAR) and HH total adherence rate (HHTAR) were analyzed. Profession-specific HHTAR and moment-specific HHTAR (for each WHO moment) were also calculated. Results: HHCAR, HHPAR and HHTAR were found as 30.8%, 34.5% and 65.3% respectively. There was a significant increase in the monthly HHTAR from 26.7% to 68.4% (P < .001). The profession-specific HHAR was found to be highest among doctors (67.5%) and nurses (66.4%). As the HHTAR increases there is a significant decrease in device associated infection (DAI) rate from 24.7 to 11.5 per 1,000 device days. Conclusions: Auditing HH and providing timely feedback significantly improved HH compliance. The need of the hour is to regularly conduct HH audit in COVID locations of all healthcare facilities to reduce HAI rate among the COVID-19 infected patients in ICUs.
Corynebacterium diphtheriae usually causes respiratory diphtheria, which is considered as a disease of toxemia but never bacteremia. Over the last few decades, cutaneous diphtheria has been increasingly reported owing to the emergence of the non-toxigenic strain, which causes locally necrotic and ulcerative lesions. Bacteremia is very rare, but the existing evidence in the literature suggests that the organism can rarely cause invasive infections such as septicemia, endocarditis, and osteoarthritis. Here, we present a rare case of C. diphtheriae causing bloodstream infections in an elderly diabetic with peripheral vascular disease, which was diagnosed incidentally on routine blood culture owing to automated identification systems viz matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) confirmed with conventional methods, and susceptibility was performed using automated VITEK 2 system (BioMérieux, Marcy-l'Étoile, France), which has aided in the timely management.
BackgroundIn the era of increased antimicrobial resistance, there are limited therapeutic options available for the treatment of bacteremia caused by multidrug-resistant organisms (MDROs). This study aims to find out the feasibility of using ceftazidime/avibactam (CZA) as a therapeutic option for bloodstream infections caused by multidrug-resistant (MDR) Enterobacterales and Pseudomonas aeruginosa based on its susceptibility profile.
Materials and methodsThe isolates were routinely subjected to antimicrobial susceptibility testing (AST) by an automated AST system (VITEK-2). Those isolates found as MDR (resistant to at least one drug for ≥3 antimicrobial classes) were tested against CZA by Kirby-Bauer's disk diffusion (kb-DD) method.
ResultsA total number of 293 MDR Enterobacterales and 31 MDR P. aeruginosa isolates were included. Of these, 87.3% of isolates were found as carbapenem-resistant (CR), whereas 12.7% of isolates were found as carbapenem susceptible. About 30.6% of MDROs were susceptible to CZA. Among carbapenem-resistant organisms (CROs), CR Klebsiella pneumoniae (33.5%) is most susceptible to CZA, compared to CR P. aeruginosa (0%) and CR Escherichia coli (3.2%). Among the MDR isolates that were susceptible to CZA (30.6%), the majority had poor susceptibility against other β-lactam-β-lactamase inhibitor (BL-BLI) agents. Among all antimicrobial agents tested against CROs, colistin (96%) was found to have the best susceptibility profile.
ConclusionIt is observed that CZA is an acceptable therapeutic option for the treatment of bacteremia caused by MDROs, especially CROs. Therefore, it is important for the laboratories to perform the AST for CZA if the healthcare settings intend to use CZA for the management of such "difficult-to-treat" bloodstream infections.
Coryneforms other than are often ignored when isolated from clinical laboratories as in most instances they represent the normal commensals of skin. was initially considered only as commensal, later it was identified as the causative agent for severe sepsis in immunocompromised patients. Here, we present a case of meningoencephalitis caused by in a 30 year old adult male with HIV and tuberculosis co-infection. Serial cerebrospinal fluid from external ventricular drainage had grown which was identified by automated MALDI-TOF system which aided in the timely diagnosis and prompt management of the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
