Medical institutions, the last defense line for the medical treatment of coronavirus disease 2019, are crucial to avoid cross-infection in hospitals. And how to reasonably arrange patient visits and achieve early detection, early reporting, early isolation, and early treatment of patients with coronavirus disease 2019 and suspected cases at the same time is an important proposition. After the outbreak of coronavirus disease 2019, West China Hospital of Sichuan University continued to supplement and improve implementation details based on the three-level pre-examination and triage of infectious diseases, and established a three-level pre-inspection and triage management mechanism more suitable for coronavirus disease 2019, and successfully applied it. This article introduces the process and results of this outpatient three-level pre-examination and triage management optimization practice, aiming to provide an experience reference for the outpatient three-level pre-examination and triage in medical institutions.
Objective To construct a quality evaluation index system for healthcare-associated infection (HAI) management, and conduct an empirical evaluation on the quality of HAI management in clinical departments. Methods The literature research method and panel discussion method were adopted to initially form the framework of HAI management quality evaluation index system, and the Delphi method and the analytic hierarchy process were used to establish the index system and determine the weights from January to December 2018. Eight comprehensive evaluation methods, such as osculating value method and technique for order preference by similarity to an ideal solution method, were used to evaluate the quality of HAI management in clinical departments of West China Hospital, Sichuan University in 2018. Kendall’s coefficient of concordance (W) was used to assess the consistency of the results. The clinical departments were ranked by the standardized total scores, which were the means of the normalized scores of the eight methods. Results A quality evaluation index system for HAI management with 3 first-level indicators and 15 second-level indicators was established finally. The results of the eight comprehensive evaluation methods for the quality evaluation of HAI management in 39 clinical departments of West China Hospital, Sichuan University were consistent (W=0.952, χ2=259.800, P<0.001). The standardized total score of Department 18 was 100, which ranked the first place. Conclusion The HAI management quality evaluation index system constructed in this study could be used in clinical departments to evaluate the quality of HAI management in combination with comprehensive evaluation methods.
Objective To investigate the occurrence of sharp instrument injuries among healthcare workers in a comprehensive teaching hospital and explore the risk factors, so as to provide scientific basis for the prevention approaches. Methods A total of 1 180 healthcare workers with sharp instrument injuries between 2011 and 2014 were included in the study. Occupational hematogenous exposure monitoring and protecting system for health workers was established and optimized. The report and treatment process was standardized. Targeted monitoring system of sharp instrument injuries was developed. Sharp instrument injuries between 2011 and 2014 were systematically collected and analyzed. Results Between 2011 and 2014, there were 1 180 health workers who had sharp instrument injuries. Health workers had the highest rate of exposure to hepatitis B virus(41.06%), followed by syphilis (13.35%). Syringe needles (27.54%), suture needles (24.15%) and scalp needles (19.58%) were the instruments that caused most of the injuries. We constructed occupational exposure records for all those with sharp instrument injuries, and performed regular follow-up. No hematogenous infections were found because of sharp instrument injuries. Conclusions Sharp instrument injuries are common in healthcare institutions. It is important to establish and perfect the occupational exposure monitoring and protecting system, so as to reduce the risk of occupational exposure for health workers in hospitals.
Objective To optimize the report procedure of infectious diseases, solve the problems during routine surveillance such as incomplete report and incorrect report, in order to improve the report quality of infectious diseases. Methods Common problems in the report cards which were systematically collected in the infectious disease report management system were analyzed. Then, through negotiation with engineers of the information center, procedures which might easily lead to errors were deleted, report procedures were optimized. Furthermore, clinicians were also trained on infectious disease report from time to time. The entire study was divided into three periods, including baseline period (from October 1, 2012 to December 31, 2013), intervention period (from January 1, 2014 to December 31, 2014) and enhanced intervention period (from January 1, 2015 to December 31, 2015). The incorrect report rate and incomplete report rate were automatically calculated and compared among the three periods to evaluate the report quality. Results Compared with the baseline period, the total incomplete rate in the enhanced intervention period decreased from 8.21% to 3.19% (χ2=103.143,P<0.001), the incorrect report rate of hepatitis B virus decreased from 32.84% to 21.63% (χ2=19.002,P<0.001), and the incorrect report rate of syphilis decreased from 24.93% to 6.86% (χ2=90.416,P<0.001). respectively. Conclusion The infectious disease report system plays a very important role in timely identification of errors and improvement of incomplete and incorrect report, and is of great significance in the management of infectious diseases.

ObjectivesTo detect the admission rate and hospital acquired rate of carbapenem-resistant Klebsiella pneumoniae (CRKP) and carbapenem-resistant Acinetobacter baumannii (CRAB) of active surveillance in Emergency Intensive Care Unit patients of West China Hospital of Sichuan University, to examine whether rectal colonization of CRKP and CRAB are associated with nosocomial infection, so as to provide a scientific basis for the prevention and control of CRKP and CRAB.MethodsA nested case-control study was conducted between April and September 2018 in Emergency Intensive Care Unit. Rectal swabs were obtained to screen CRAB and CRKP, and the admission rate of colonization was calculated. According to whether infected with CRKP/CRAB, the patients were divided into case group (infection group) and control group (noninfection group) to determine whether colonization of CRKP/CRAB were independent risk factors for nosocomial infection using logistic regression model.ResultsThe admission rate of CRKP and CRAB patients were 4.08% (18/441) and 8.78% (38/433), and the nosocomial infection rate was 3.63% (16/441) and 18.01% (78/433) separately. Multivariate analysis showed that rectal colonization of CRKP [odds ratio=5.438, 95% confidence interval (1.643, 17.999), P=0.006] was an independent risk factor for nosocomial infection. However, there was no statistical correlation between rectal colonization of CRAB and nosocomial infection [odds ratio=1.449, 95% confidence interval (0.714, 2.942), P=0.305].ConclusionsThe rectal colonization rate of CRAB is higher than that of CRKP, but it does not increase the risk of CRAB infection in patients. Rectal colonization of CRKP is an important factor for infection of patients. Therefore, early detection of CRKP through active surveillance and taking control measures can help reduce the risk of its spread in the hospital.
Since the outbreak of coronavirus disease 2019 (COVID-19), health authorities at all levels have issued many prevention and control schemes, guidelines, and notices, and medical institutions have also formulated hospital-level COVID-19 prevention and control measures accordingly. However, the epidemic prevention and control work can only be done well when the prevention and control measures are effectively implemented. West China Hospital of Sichuan University has adopted the two-level (hospital-level and department-level) supervision. By clarifying the content and frequency of two-level supervision and adopting multiple forms of supervision, a complete supervision system covering the whole hospital has been formed. Through supervision, risk points in prevention and control were identified and continuous improvement was carried out to promote the implementation of prevention and control measures. This paper introduces the application of two-level supervision in COVID-19 prevention and control in West China Hospital of Sichuan University, providing a reference for peers.
Objective To investigate the predictors for carbapenem-resistant Acinetobacter baumannii, Enterobacteriaceae and Pseudomonas aeruginosa (CR-AEP) as the pathogens of bloodstream infection (BSI) for intensive care unit (ICU) patients. Methods A retrospective case-control study based on ICU- healthcare-associated infection (HAI) research database was carried out. The patients who have been admitted to the central ICU between 2015 and 2019 in the ICU-HAI research database of West China Hospital of Sichuan University were selected. The included patients were divided into two groups, of which the patients with ICU-acquired BSI due to CR-AEP were the case group and the patients with BSI due to the pathogens other than CR-AEP were the control group. The clinical features of the two groups of patients were compared. Logistic regression model was used to identify the predictors of BSI due to CR-AEP.ResultsA total of 197 patients with BSI were included, including 83 cases in the case group and 114 cases in the control group. A total of 214 strains of pathogenic bacteria were isolated from the 197 BSI cases, including 86 CR-AEP strains. The results of multivariate logistic regression analysis showed that previous use of tigecycline [odds ratio (OR)=2.490, 95% confidence interval (CI) (1.141, 5.436), P=0.022] was associated with higher possibility for CR-AEP as the pathogens of BSI in ICU patients with BSI, while previous use of antipseudomonal penicillin [OR=0.497, 95%CI (0.256, 0.964), P=0.039] was associated with lower possibility for that. Conclusion Previous use of tigecycline or antipseudomonal penicillin is the predictor for CR-AEP as the pathogens of BSI in ICU patients with BSI.
During the medical rescue after the Wenchuan earthquake, in order to prevent hospital environmental pollution and cross infection, the nosocomial infection control committee of West China Hospital of Sichuan University immediately initiated the emergency response plan, improved the triage system, and organized multi-disciplinary infection control groups to improve the triage of the wounded and the infection control of the emergency department. At the same time, we regulated the individual behavior of healthcare professionals and took appropriate measures for personnel protection so as to ensure the safety of both the wounded and healthcare professionals.
Objective To survey the current situation of the sharp injury in medical workers, and to provide scientific evidence for the prevention and protection of sharp injury. Methods Through applying the questionnaire of sharp injuries designed by Zhongshan Hospital, Shanghai Fudan University, 10% of the workers in all departments of West China Hospital of Sichuan University were selected as respondents according to their job categories. The main contents of the survey included the general information of respondents, reporting after sharp injuries, training participation, and the exposure sources, operations, premises and equipments related to sharp injuries over the past one year.Results Of 840 questionnaires distributed, 100% were valid. The ratio of male was 23% while the female was 72%. There were 50.20% of all respondents who once got injured, and 75% of the respondents having the history of sharp injury worked less than 10 years. The nurses, house keepers and physicians were in the top three positions of suffering from sharp injury; and the operating room was ranked as the highest risk department for sharp injuries. The known haematogenous exposure sources were 69 cases of hepatitis B, 19 syphilis, 6 hepatitis C, and 3 HIV. There were 62% of the respondents who had ever attended related training, and only 11.61% of the injured respondents reported their sharp injuries. Conclusion The incidence rate of the sharp injury is high, but the report rate is low. The operating room is the high risk department, and nurses, house keepers, and physicians are the high risk population for sharp injuries. The prevention and protection and training for sharp injury in target departments and population should be strengthened.
