RESUMEN
BACKGROUND: Healthcare-associated infections (HAIs) are still a major health threats worldwide. Traditional surveillance methods involving manual surveillance by infection control practitioners (ICPs) for data collection processes are laborious, inefficient, and generate data of variable quality. In this study, we sought to evaluate the impact of surveillance and interaction platform system (SIPS) for HAIs surveillance compared to manual survey in tertiary general hospitals. METHODS: A large multi-center study including 21 tertiary general hospitals and 63 wards were performed to evaluate the impact of electronic SIPS for HAIs. RESULTS: We collected 4,098 consecutive patients and found that the hospitals installed with SIPS significantly increased work efficiency of ICPs achieving satisfactory diagnostic performance of HAIs with 0.73 for sensitivity, 0.81 for specificity and 0.81 area under the curve (AUC). However, there were significant heterogeneity own to regions, time of SIPS installation, departments and sample size. CONCLUSIONS: SIPS significantly improved ICPs efficiency and HAIs monitoring effectiveness, but there were shortcomings such as untimely maintenance and high cost.
RESUMEN
BACKGROUND: Risk factors for healthcare associated infections (HAIs) following surgical repair of acute type A aortic dissection (TAAD) has not been well defined. METHODS: This was a retrospective study of patients treated between Jan 2013 and May 2016 at the large tertiary teaching hospital in Jiangsu, China. Logistic regression analysis was performed to investigate the association patients with acute TAAD who underwent ascending aortic and arch replacement under deep hypothermic circulatory arrest (DHCA) and healthcare associated infections during hospitalization. RESULTS: Of the final 210 patients with aortic dissection (AD) admitted to our hospital, 100 patients had TAAD (100/210, 47.62%), which were then allocated to the HAIs group (n=36) and Non-HAIs group (n=64). We found that DCHA >29 min [odds ratio (OR) =2.60, 95% confidential interval (CI), 1.01-6.80, P=0.048], preoperative PLT <171×109/L (OR =3.62; 95% CI, 1.33-9.79; P=0.011) and D-dimer >4.25 mg/L (OR =2.83; 95% CI, 1.07-7.47; P=0.035) were independently associated with the occurrence of HAIs for the patients with TAAD following surgical repair. Hosmer-Lemeshow statistic of the model suggested perfect model discrimination from a perfect fit (χ2=4.77, P=0.6883). Logistic model was verified when the area under receiver operating characteristic (ROC) curve was equal to 0.7665. CONCLUSIONS: TAAD patients with longer DHCA time, lower preoperative PLT, higher serum D-dimer would significantly increase the risks after surgical repair of arch replacement.
RESUMEN
OBJECTIVE: To identify risk factors of ventilator-associated pneumonia (VAP) in pediatric intensive care unit (PICU). METHODS: PubMed, Ovid, Web of Science, the Cochrane Library and references of retrieved articles were searched without language limitation. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by using both the Mantel-Haenszel fixed-effect and the DerSimonian-Laird random-effects models. RESULTS: Out of the 205 initially retrieved articles, 9 papers were included. All 4,564 patients were enrolled, including 213 patients with VAP and 4,351 patients without VAP. Among fourteen risk factors, six factors had statistical significances. Risk factors of VAP and its value of OR were as follows: genetic syndrome (OR =2.04; 95% CI: 1.08-3.86), steroids (OR =1.87; 95% CI: 1.07-3.27), reintubation or self-extubation (OR =3.16; 95% CI: 2.10-4.74), bloodstream infection (OR =4.42; 95% CI: 2.12-9.22), prior antibiotic therapy (OR =2.89; 95% CI: 1.41-5.94), bronchoscopy (OR =4.48; 95% CI: 2.31-8.71). CONCLUSIONS: Special methods of preventions should be taken in the light of risk factors of VAP in PICU so as to decrease the rate.
