Medical institutions of China still face two challenges in hospital infections currently: one challenge is from infection, including infectious diseases, multidrug-resistant bacteria healthcare-associated infection (HAI), and classic HAI; the another challenge comes from the management of HAI in medical institutions, such as lack of full-time staff and insufficient capacity, inadequate infection control organizations, insufficient awareness of infection control among medical staff, and unbalanced development. To cope with these severe challenges, we must do the following three aspects: establishing the discipline of HAI, and improving people’s infection control ability through human-orienting; improving the management organization and system of HAI; improving the awareness of infection control among all medical staff, carrying out scientific and orderly infection prevention and control work in accordance with the law, and adhering to evidence-based infection control.
With nearly four decades of progress in healthcare-associated infection prevention and control in China, the national quality control efforts in this field have been ongoing for the past ten years, advancing rapidly with significant achievements. Over the last decade, the team of infection control professionals involved in quality management and control in China has consistently expanded, accompanied by an enhancement of their skills. Management capabilities have steadily grown, and operational mechanisms have been continuously refined. As public hospitals transition into a new phase of high-quality development, emphasizing refined management models and intrinsic development of medical quality, it becomes crucial to further fortify the foundation and foster innovation in infection control work to ensure quality. This article provides an overview of the establishment and implementation of the National Center for Quality Control of Infection Prevention and Control, examines the current shortcomings and challenges in the field, and collectively explores the positioning and direction of the development of quality control efforts for infection prevention and control in China.
This paper expounds the classification and characteristics of healthcare-associated infections (HAI) surveillance systems from the perspective of the informatization needs of HAI monitoring, explains the determination requirements of numerator and denominator in the surveillance statistical data, and introduces the regular verification for auditing the quality of HAI surveillance. The basic knowledge of machine learning and its achievements are introduced in processing surveillance data as well. Machine learning may become the mainstream algorithm of HAI automatic monitoring system in the future. Infection control professionals should learn relevant knowledge, cooperate with computer engineers and data analysts to establish more effective, reasonable and accurate monitoring systems, and improve the outcomes of HAI prevention and control 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.
Healthcare-associated infection management has advanced rapidly in recent years. With the development of more standards and guidelines, infection control measures become more standardized and evidence-based. Evidence-based measures are increasingly applied in infection control, which promote more studies on the prevention and control of healthcare-associated infections. Furthermore, more new ideas of infection control have emerged, with old ones being challenged. The hand hygiene reform, multidrug-resistant organisms, and surgical site infections become the hot topics in recent years. In addition, whole-genome sequencing also provides more bases for understanding pathogen transmission in hospitals. Based on the high-quality studies published in recent years, this opinion review discusses these hot topics in the prevention and control of healthcare-associated infections.
Healthcare-associated infection outbreaks are a serious threat to patient safety and often cause serious consequences. The use of genotyping methods to identify the source of infection and the route of transmission in outbreaks is a critical point in controlling outbreaks. Recently, the use of whole-genome sequencing (WGS) makes it faster and much more accurate. Compared with traditional methods, WGS can distinguish highly correlated pathogen lineages, track infection source accurately and help researchers understanding the propagation dynamics model, and even provide more target intervention information. The application of WGS technology in healthcare-associated infection outbreak investigation and control is reviewed in this paper, and its advantages and challenges are also evaluated.
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.
