ObjectiveTo explore the continuous changing trend of healthcare-associated infection prevalence rate in a children’s hospital.MethodsFrom July 2012 to November 2018, a cross-sectional survey was conducted to investigate the prevalence of healthcare-associated infections in hospitalized children for seven consecutive years by combining case-checking and bedside survey.ResultsA total of 10 310 hospitalized children were investigated in the past seven years. The incidence of healthcare-associated infections from 2012 to 2018 was 2.08%, 4.84%, 1.59%, 3.76%, 1.63%, 1.74%, and 2.08%, respectively, showing a statistically significant downward trend (LLA=7.631, P=0.006). The departments with higher proportion of healthcare-associated infections were pediatric surgery (50.0%), pediatric medicine (44.8%), neonatal medicine (2.8%), and intensive care units (2.4%) . Viruses (38.8%) were the most common pathogens of healthcare-associated infections, followed by Gram-negative bacteria (34.3%) .ConclusionsThe prevalence of healthcare-associated infections in the children’s hospital showed a downward trend year by year. Pediatric surgery is the most common occurrence department, and viruses are the most common pathogens. It can provide evidence for prevention and control of healthcare-associated infection in children’s hospitals.
ObjectiveTo investigate the prevalence rate of nosocomial infection in West China Hospital of Sichuan University and to analyze the implementation effect of nosocomial infection control measures, so as to provide reference for infection control.MethodsAn investigation of the prevalence rate of nosocomial infections was performed on patients who were admitted in West China Hospital of Sichuan University from 0:00-24:00 on a day of every late June from 2012 to 2018 by using bedside investigation in combination with inpatient medical record query, and the data was verified, summarized, and statistically analyzed by the professionals of Nosocomial Infection Management Department.ResultsFrom 2012 to 2018, the prevalence rates of nosocomial infections were 5.19%, 4.20%, 3.94%, 4.26%, 4.29%, 4.25%, and 2.97% in West China Hospital of Sichuan University, which tended to decline (χ2=32.826, P<0.001). There was no significant difference in annual total infection rate in the Department of Internal Medicine, however, the infection rate in the Department of Hematology tended to decline (χ2=6.127, P<0.05); in the Department of Surgical Medicine, the total infection rate tended to decline(χ2=18.721, P<0.001); in particular, the infection rate in the Department of Thoracic Surgery tended to decline(χ2=3.906, P<0.05); the annual difference in infection rate in the Intensive Care Unit (ICU) was not statistically significant. The key site of nosocomial infection was dominated by the lower respiratory tract, and the annual difference was not statistically significant. In particular, postoperative pneumonia has increased since 2014 (χ2=9.56, P=0.002). The nosocomial pathogens which had the highest constituent ratio over the years were Acinetobacter baumannii (in 2012, 2013, 2014, 2017, and 2018), Klebsiella pneumonia (in 2015), and Escherichia coli (in 2016). The annual difference in rate of antimicrobial use was not statistically significant(χ2=3.75, P=0.053), while the rate of antimicrobial use in the ICU tended to decline (χ2=30.42, P=0.000).ConclusionsThe prevalence rate of nosocomial infection in West China Hospital of Sichuan University tends to decline. However, sufficient attention still requires to be paid to lower respiratory tract infection, particularly for patients with postoperative pneumonia.
ObjectiveTo understand the burden of stroke disease and age-period-cohort effects in China from 1990 to 2021, and to provide scientific basis for formulating relevant prevention and treatment strategies. MethodsBased on GBD2021 data, the Joinpoint regression model was used to analyze the trend of incidence rate, mortality and DALYs rate of stroke, and the APC model was used to analyze the impact of age, period and birth cohort on the incidence and mortality of stroke. ResultsFrom 1990 to 2021, the standardized incidence rate, standardized mortality rate and standardized DALYs rate of stroke in China showed an overall downward trend, with AAPC of −0.37% (95%CI −0.45% to −0.29%), −1.79% (95%CI −1.99% to −1.59%), and −1.93% (95%CI −2.07% to −1.80%), respectively. The results of the age-period-cohort model showed that the incidence and mortality risks of stroke increased with age; The risk of female onset remained stable in the early stage but increased rapidly in the later stage, while the risk of male mortality showed a slight upward trend; The risk of onset and death generally decreased with the passage of the birth cohort. Hypertension had always been the primary risk factor for stroke, and metabolic factors such as high blood sugar had become the main factors affecting disease burden. ConclusionThe burden of stroke disease in China is still relatively heavy, and differentiated intervention measures should be developed for different age and gender groups based on controllable risk factors, especially focusing on the elderly and male population.
