Objective To evaluate the efficiency and security of physical exercise with low intensity against malnutrition and sarcopenia in patients with cirrhosis. Methods Between December 2014 and October 2015, 37 patients with cirrhosis were divided into two groups according to their willings, with 19 in the exercise group and 18 in the control group. Endurance of the exercise for 3 months were recorded. Mid-arm circumference, " up and go” time, width of portal vein and Child-Pugh score were compared before and after the research between the two groups. Results Three months later, the mid-arm circumference and the " up and go” time of the exercise group [(33.99±2.15) cm, (9.17±0.35) s] were better than those before the exercise [(32.09±2.58) cm, (9.77±0.46) s] and those in the control group [(31.93±2.04) cm, (9.76±0.30) s], and the differences above were all statistically significant (P<0.05). The change of the width of portal vein was positively correlated with pre-exercise body mass index in overweight patients (r=0.93, P=0.007). Conclusions Physical exercise with low intensity is safe and effective against malnutrition and sarcopenia in patients with cirrhosis. Overweitht patiens or malnutrition at the early stage may benefit more.
ObjectiveTo investigate the disinfection effect of dry-fogging hydrogen peroxide (DFHP) on ambulance inner surfaces.MethodsThis study was carried out using simulated field test and field test from October to December 2018. In the simulated field test, the carriers with Geobacillus stearothemopilus (ATCC12980) spores were placed in 6 places in the ambulance, and disinfected for 60 minutes with DFHP of 0.38–0.72 g/m3. The carriers were cultured for up to 7 days to observe whether the bacteria were eliminated. Before and after the DFHP disinfection, the microbial sampling of the surface in the ambulance was carried out, and the colonies were counted after the cultivation.ResultsThe eliminating rate of the bacteria carriers on the uncovered surface was 100% (20/20), and that of the covered surface was 10% (1/10). The pass rate of microbial sampling was 100% (26/26).ConclusionsThe DFHP had a significant decontamination effect on the ambulance inner uncovered surfaces. The DFHP equipment is automated and their disinfecting quality is consistent, therefore it is suitable for the disinfection of ambulance inner surfaces. But the limitation of disinfection effect on covered surfaces should be avoided.
Objective To investigate the risk factors of central line-associated bloodstream infection (CLABSI) and provide clinical guidance for reducing the incidence of CLABSI. Methods The clinical data of patients with central venous catheter catheterization in Sichuan Provincial People’s Hospital between January 2018 and December 2021 were retrospectively collected. According to whether CLABSI occurred, the patients were divided into CLABSI group and non-CLABSI group. The data of patients were analyzed and the risk factors of CLABIS were discussed. Results A total of 43 987 patients were included. Among them, there were 63 cases in the CLABSI group and 43924 cases in the non-CLABSI group. The incidence of CLABSI was 0.18/1 000 catheter days. Multivariate logistic regression analysis showed that admission to intensive care unit (ICU) [odds ratio (OR)=74.054, 95% confidence interval (CI) (22.661, 242.005), P<0.001], hemodialysis [OR=4.531, 95%CI (1.899, 10.809), P=0.001] and indwelling catheter days [OR=1.017, 95%CI (1.005, 1.029), P=0.005] were independent risk factors for CLABSI. A total of 63 strains of pathogenic bacteria were isolated from the 63 patients with CLABSI. Among them, 28 strains of Gram-positive bacteria, 25 strains of Gram-negative bacteria and 10 strains of Candida. Conclusions Admission to ICU, hemodialysis and long-term indwelling catheter are independent risk factors for CLABSI. The prevention and control measures of CLABSI should be strictly implemented for such patients to reduce the risk of infection.
Objective To investigate the risk factors of multidrug-resistant organism (MDRO) infection in patients with car accident injuries in intensive care unit (ICU), providing clinical guidance for reducing MDRO infection in car accident patients. Methods The clinical data of patients with car accident injuries in Sichuan Provincial People’s Hospital between January 1st 2019 and February 28th 2023 were collected, and the relevant data were analyzed retrospectively to explore the risk factors of MDRO infection. Results A total of 141 patients with car accident injuries were collected, of whom 30 had MDRO infection. The proportions of males (P=0.012), indwelling catheters (P=0.005), mechanical ventilation (P=0.001), length of hospital stay (P<0.001), and total treatment costs (P<0.001) in the infection group were higher than those in the non-infection group. Multiple logistic regression analysis showed that male [odds ratio (OR)=3.797, 95% confidence interval (CI) (1.174, 12.275), P=0.026], mechanical ventilation [OR=4.596, 95%CI (1.538, 13.734), P=0.006], and length of hospital stay≥20 d [OR=1.014, 95%CI (1.001, 1.028), P=0.037] were independent risk factors for MDRO infection in car accident patients. Conclusions Male, mechanical ventilation, and increased length of hospital stay are independent risk factors for MDRO infection in car accident patients. For such patients, the prevention and control measures of hospital infection should be strictly implemented to reduce the risk of infection.

ObjectiveTo measure and evaluate the economic burden of hospital infection in Sichuan, and provide a basis for targeted economic evaluation of healthcare-associated infection (HAI).MethodsIn hospitals participating in the 2016 Sichuan provincial prevalence survey of HAI, matched cases were used to extract cases and controls, and then a multi-center nested case-control study was conducted.ResultsA total of 225 pairs/450 patients were selected in 51 hospitals, and 175 pairs/350 patients were successfully matched. The median of the difference of hospitalization costs between matched-pairs were RMB 3 362.0, and the difference was statistically significant (Z=3.275, P<0.001).ConclusionsThe hospitalization costs caused by HAI should be given special attention in the current medical insurance reform. Efforts need to be taken to reduce the hospitalization costs caused by HAI.
ObjectiveTo explore the risk factors influenced postoperative complications of colon cancer. MethodsIn this study, 114 patients diagnosed definitely as colon cancer were enrolled from January 2009 to April 2010 in this hospital. The patients were divided into the complication group and non-complication group according to the occurrence of postoperative complications during hospital day. Furthermore, clinicopathological features and operative parameters of patients were compared in two groups, and independent factors for postoperative complications were identified by multiple regression analysis. ResultsThere were statistical differences between two groups in operation time (t=2.034, P=0.032), diabetes mellitus (χ2=5.920, P=0.015), differentiation degree of tumor (χ2=7.163, P=0.028), hospital stay (χ2=0.411, P=0.026), and ASA grades (χ2=11.585, P=0.009). The morbidity of patients with operative time gt;200 min was significant higher than that ≤100 min (χ2=8.884, P=0.003) and 100-200 min (χ2=7.318, P=0.007). The morbidity of patients with ASA Ⅳ grade was higher than that with ASA Ⅰ grade (χ2=13.426, P=0.000). For tumor differentiation, the morbidity of patients with well-differentiated tumor was higher than that with moderately differentiated tumor (χ2=4.950, P=0.026) and poorly differentiated tumor (χ2=7.476, P=0.006). The hospital stay (P=0.009), age (P=0.024), diabetes mellitus (P=0.018), and ASA grade (P=0.001) were the independent factors for postoperative complications by multivariate regression analysis. ConclusionThe physical quality indexes are the mostly common risk factors of postoperative complications for colon cancer, emphasizing on the high-risk factors and making a targeted and individual treatment plan for each patient are of great important to improve the prognosis.
Objective To understand the current situation of healthcare-associated infection (HAI) in comprehensive hospitals with a number of beds≥900, and provide a reference for the next step in formulating HAI prevention and control measures. Methods The data on the prevalence rate of HAI in comprehensive hospitals with a number of beds≥900 of Yunnan Province between 2020 and 2022 were retrospective collected. The HAI situation and trend in each year were analyzed. Results A total of 119 comprehensive hospitals were included, with 166 745 patients surveyed and 3 237 cases of HAI. Lower respiratory tract infection and urinary tract infection were the most common sites. The department with the highest incidence of hospital infections was the intensive care unit, followed by neurosurgery and hematology. The prevalence rates of HAI showed a downward trend from 2020 to 2022 (2.08% vs. 1.99% vs. 1.79%, χ2=14.301, P<0.001). A total of 1 315 strains of hospital-acquired pathogens were detected, all of which were mainly Gram-negative bacteria, with Escherichia coli and Klebsiella pneumoniae being more common. The rate of antibiotics use and the rate of pathogen testing showed an upward trend from 2020 to 2022 (χ2=79.233, 23.866, P<0.001), the infection rate of incision site and the prophylactic use rate of antimicrobial drugs in patients with class Ⅰ surgery both showed a decreasing trend (χ2=15.551, 6.311, P<0.05). Conclusions The prevalence of infection in comprehensive hospitals of Yunnan Province is decreasing. But the supervision of key departments, the implementation of pathogen prevention and control measures, and the rational use of antibiotics in inpatients are still the focus of future work.
