Hospital-acquired bloodstream infection (BSI) is associated with high morbidity and mortality and increases patients’ length of stay (LOS) and hospital charges. Zhang, et al. (2020) sought to calculate LOS and charges attributable to BSI and compare results among different models.
A retrospective observational cohort study was conducted in 2017 in a large general hospital, in Beijing. Using patient-level data, the researchers compared the attributable LOS and charges of BSI with three models: 1) conventional non-matching, 2) propensity score matching controlling for the impact of potential confounding variables, and 3) risk set matching controlling for time-varying covariates and matching based on propensity score and infection time.
The study included 118,600 patient admissions, 557 (0.47%) with BSI. Six hundred fourteen microorganisms were cultured from patients with BSI. Escherichia coli was the most common bacteria (106, 17.26%). Among multi-drug resistant bacteria, carbapenem-resistant Acinetobacter baumannii (CRAB) was the most common (42, 38.53%). In the conventional non-matching model, the excess LOS and charges associated with BSI were 25.06 days (P < 0.05) and US$22041.73 (P < 0.05), respectively. After matching, the mean LOS and charges attributable to BSI both decreased. When infection time was incorporated into the risk set matching model, the excess LOS and charges were 16.86 days (P < 0.05) and US$15909.21 (P < 0.05), respectively.
The authors say this is the first study to consider time-dependent bias in estimating excess LOS and charges attributable to BSI in a Chinese hospital setting. We found matching on infection time can reduce bias.

magnificent issues altogether, you just gained a logo new reader. What may you suggest in regards to your submit that you simply made a few days ago? Any positive?
Hi there friends, its great post about teachingand fully explained, keep it up all the time.

Fine way of explaining, and pleasant article to take data concerning my presentation topic, which i am going to deliver in institution of higher education.
I don’t even know the way I stopped up here, however I assumed this post was good. I don’t recognise who you are however definitely you are going to a famous blogger if you are not already. Cheers!
