ObjectiveTo investigate the risk factors, prognostic factors and prognosis of Multidrug-Resistant Acinetobacter Baumannii (MDR-AB) infection of lower respiratory tract in Intensive Care Unit (ICU) of the Second Affiliated Hospital of Anhui Medical University. MethodsUsing retrospective analysis, we reviewed and compared clinical data of 77 AB infections in lower respiratory tract cases in ICU from January 2013 to March 2015. According to the resistance, patients were divided into a MDR-AB group and a NMDR-AB group. Then the risk factors, prognostic factors and prognosis of MDR-AB infection were analyzed. ResultsA total of 58 cases in the MDR-AB group, 19 cases in the NMDR-AB group were included. The result showed that, the MDR-AB infection in lower respiratory tract could significantly prolong the length of ICU stay (18.5±16.0 vs. 10.6±9.3 days, P<0.05) and increase the mortality (44.8% vs. 11.1%, P<0.01). Logistic regression analysis showed that the independent risk factors for MDR-AB infection in lower respiratory tract included Acute Physiology and Chronic Health Evaluation Ⅱ (Apache Ⅱ) score >15 (OR=0.138, 95%CI 0.03 to 0.625, P=0.01) and use of carbapenems (OR=0.066, 95%CI 0.012 to 0.0346, P=0.001). The independent prognostic factors included placement of drainage tube (OR=8.743, 95%CI 1.528 to 50.018, P=0.015) and use of vasoactive drugs (OR=12.227, 95%CI 2.817 to 53.074, P=0.001). ConclusionThe MDR-AB infection in lower respiratory tract can significantly prolong the length of ICU stay and increase the mortality. The Apache Ⅱ score >15 and use of carbapenems are the risk factors, and the placement of drainage tube and use of vasoactive drugs can increase the mortality of MDR-AB infection of lower respiratory tract in ICU.
目的 分析多功能空氣消毒機在普通內科病房的動態消毒效果，為病房空氣質量的控制提供參考依據。 方法 2010年9月－2011年4月對普通內科病房在動態狀態下進行細菌檢測并使用多功能空氣消毒機消毒，并就消毒前后的空氣細菌菌落總數進行分析比較。 結果 在動態狀態下，病房關門關窗并開啟空調機時，使用多功能空氣消毒機消毒前的空氣細菌菌落總數顯著高于消毒后，差異有統計學意義（P＜0.05）；病房在開門開窗時，使用多功能空氣消毒機消毒前后的空氣細菌菌落總數比較，差異無統計學意義（P＞0.05）。 結論 普通內科病房在關門關窗并開啟空調機動態狀態下，使用多功能空氣消毒機可以降低空氣細菌菌落總數，改善房間空氣質量。
Objective To explore the effect of “net bottom” management in the control of device-associated infections (DAIs) in elderly patients by setting infection monitoring doctors and nurses in the emergency intensive care unit (EICU). Methods Elderly patients who aged≥60 years old admitted to the EICU of the First People’s Hospital of Lianyungang between April 2018 and March 2021 were selected as the research subjects. A “net bottom” management mode was established and implemented for the purpose of infection prevention and control, taking medical and other departments as the coordination and management subjects, and infection monitoring doctors and nurses as the core. The effectiveness of the management intervention was evaluated by comparing the incidences of DAIs in elderly patients, the compliance rates of medical staff in hand hygiene, and the consumption of hand sanitizer per bed day in EICU among the primary stage (from April 2018 to March 2019), intermediate stage (from April 2019 to March 2020), and later stage (from April 2020 to March 2021). Results During the primary stage, intermediate stage, and later stage, there were 540, 497, and 507 elderly inpatients in EICU monitored, respectively, and the incidences of nosocomial infections were 7.22% (39/540), 5.84% (29/497), and 4.14% (21/507), respectively, showing a decreasing trend (χ2trend=4.557, P=0.033). The incidences of ventilator-associated pneumonia, central line-associated bloodstream infections, and catheter-associated urinary tract infections decreased from 4.82‰, 2.53‰, and 0.95‰, respectively in the primary stage, to 0.51‰, 1.01‰, and 0.53‰, respectively in the later stage, among which the difference in the incidence of ventilator-associated pneumonia was statistically significant (P<0.05). The hand hygiene compliance rate of EICU medical staff increased from 70.39% to 86.67% (P<0.05), and the consumption of hand sanitizer per bed day increased from 33.70 mL to 67.27 mL. The quarterly hand hygiene compliance rate was positively correlated with the quarterly consumption of hand sanitizer per bed day (rs=0.846, P=0.001), and negatively correlated with the quarterly incidence of nosocomial infections (rs=–0.769, P=0.003). Conclusion The “net bottom” management by setting up infection monitoring doctors and nurses in the EICU and multi-department collaboration can reduce the incidence of DAIs in elderly patients in EICU, which plays a positive role in promoting the hospital infection management and improving the quality of hospital infection management.
ObjectiveTo investigate the causes of ventilator-associated pneumonia (VAP) in patients with tumor in Intensive Care Unit (ICU), and take effective intervention measures to reduce the incidence of VAP. MethodsThe targeted monitoring was conducted for the ICU patients who underwent the mechanical ventilation for over 48 hours from January 2013 to December 2014. Then the conventional nursing measures where adopted in 2013 without any field intervention measure implemented. While the prevention and control method was conducted in 2014 and the causes of VAP was valued and anyzed. ResultsAfter adopting intervention measures, the thousand-day rate of VAP decreased from 8.71‰ before the interventions to 2.30‰ after the interventions. The utilization rate of ventilators increased from 63% to 72% after the interventions were taken in 2014. The constituent ratio of the multidrug-resistant bacteria among the isolated pathogens in each year presented a downward trend. ConclusionVAP is common in ICU patients. It is necessary to reach preventive measures and designated position and ventilator management so as to prevent the occurrence of new nosocomial infection.
Ambulatory surgery ward is a fast and effective way of treating, nursing and patients’ education. We report the practice of ambulatory surgery ward in West China Hospital of Sichuan University about patients’ reception, treatment and nursing, medical safety, health education and post-operative follow-up. Results show that ambulatory surgery ward would guarantee patients’ safety, shorten hospitalization days and decrease medical cost, with more than 98% of patients’ satisfaction.
