Objective To understand the current situation of nosocomial infection management quality control centers at the municipal and county levels in Guizhou, so as to provide measures for promoting the construction of nosocomial infections management quality control centers at all levels in Guizhou. Methods From September 26th to October 12th 2023, based on the mobile network platform survey questionnaire of the infection prevention and control workshop, a survey was conducted on the establishment, personnel, information technology level, management, and quality control work of the nosocomial infection management quality control centers at the municipal and county levels in Guizhou. Results Nine prefecture-level cities/autonomous prefectures in Guizhou had established municipal-level nosocomial infection management quality control centers. The professional background of the staff at the municipal and county-level quality control centers was mainly nursing (accounting for 36.4% and 58.4%, respectively), and their educational background was mainly undergraduate (accounting for 70.5% and 83.3%, respectively). No quality control center at the municipal or county level had established an information-based quality control platform for nosocomial infection management within the region. Most county-level quality control centers did not have special funds (87.5%), and there were still 16 (25.0%) county-level quality control centers that had not established relevant systems for work and management. The main forms of quality control work carried out by each center were organizing training, on-site inspections, guidance and evaluation, and most of them were conducted irregularly. Conclusions Guizhou has basically formed a quality control system for nosocomial infection management at the provincial, municipal, and county levels. However, the nosocomial infection management quality control network has not fully covered all districts, and policies, funding support, and personnel allocation are still insufficient. Health administrative departments and quality control centers at all levels need to unify monitoring standards and quality control norms, strengthen supervision, improve quality control capabilities, and improve training systems to achieve standardization and normalization of quality control work throughout the province and improve quality control efficiency.
In recent years, the Chengdu Municipal Thoracic Surgery Quality Control Center has preliminarily established a regional quality control system for thoracic surgery through the development of standards, data reporting, and on-site supervision, achieving phased improvements. This review summarizes the current development of Chengdu’s thoracic surgery quality control system, including its organizational structure and scoring methodology, quality indicators based on structure–process–outcome, information technology infrastructure, and multicenter collaboration experiences, and outlines trends in surgical volume, minimally invasive procedure rates, human resources, and care quality metrics. It also analyzes existing challenges such as inter-hospital quality disparities and insufficient interoperability among information platforms. Drawing on domestic and international best practices, we propose development strategies to further enhance the homogenization and continuous improvement of thoracic surgery quality in the region. The Chengdu experience could offer a valuable model for building regional thoracic surgery quality control systems nationwide and for integration with the national quality control platform.
Epigenetics refers to the modification effect of external and internal environmental factors on genes under the premise of the unaltered genetic sequence, leading to changes in gene expression level or function, and thereby affecting various phenotypes or disease outcomes. In recent years, epigenetics has attracted increasing attention. Among them, DNA methylation has been shown to be closely related to human development and the development of disease. However, the high-dimensional omics data generated by genome-wide methylation detection can comprehensively reflect the overall and local epigenetic modifications at the genome level, which has become one of the main research contents in this field. Based on genome-wide methylation chip data, this paper summarized the quality control process of this omics data, common epigenetic omics correlation statistical analysis methods and ideas, and visualization realization of main results based on SAS JMP Genomics 10 software, so as to provide reference for similar studies.
With the rapid development of the field of interventional therapy of cardiac valve, the innovative researches of interventional therapy of cardiac valve products have become the focus of global research. At present, there is a serious shortage of interventional valvular medical devices on the market in China, and large-scale interventional valve products are undergoing early human trials or confirmatory clinical trials. The effective quality control of clinical trials is of great significance to ensure that clinical trial data can be used to support the marketing of device products. By analyzing the problems in clinical trials quality control of interventional valvular medical devices in our hospital, and combining the characteristics of device products and diseases, we explore the key points of quality control and provide reference for the implementation and completion of high-quality clinical trials.
Giant thoracic tumor is currently one of the diagnostic and therapeutic challenges of thoracic surgery, with no established guideline or standard for diagnosis and treatment. The quality control of individualized surgical strategy and perioperative management with multi-disciplinary participation is the key to ensure the safety and improve the prognosis of patients. Based on the clinical experience of our institution and others, we hereby discussed and summarized the basic principles, surgical strategies and perioperative management of giant thoracic tumor, aiming to provide a reference of quality control.
Establishing and improving the quality control system of drug clinical trial institutions is the key to ensure the quality of clinical trial. In recent years, the number of drug clinical trial has been continuously improved, and the quality control requirements have been continuously improved. However, in clinical work, the workload of medical staff is heavy, and the energy devoted to clinical trial is limited. Clinical research coordinator (CRC), as a participant and coordinator of clinical trial, has carried out transactional work related to non-medical judgment under the authorization and guidance of researchers, and has undertaken any specific work in clinical trial. Based on the quality control management experience of nosocomial CRC and hospital drug clinical trial institutions in West China Hospital of Sichuan University, this paper discusses the mode of nosocomial CRC participating in clinical trial quality control. By participating in the quality control of clinical trial, the nosocomial CRC has improved the quality control efficiency, enriched the quality control team and improved the overall level of CRC. This model enriches the quality control system of drug clinical trial.
Objective To monitor surgical quality and analyze learning curve of minimally invasive totally thoracoscopic cardiac surgery. Methods We retrospectively analyzed the clinical data of 150 consecutive patients who underwent minimally invasive totally thoracoscopic cardiac surgery in the Guangdong General Hospital between January 2013 and December 2015. There were 60 males and 90 females at age of 43.1 years. There were 60 patients with atrial or ventricular septal defect repair, 12 patients with cardiac tumor resection, 53 patients with mitral valve replacement and 25 patients with mitral valve repair. According to the surgical sequence, all the patients were divided into 3 groups including a group A, group B, and group C with 50 patients in each group (every 10 patients as a sequence, every 5 sequence as a group). Surgical outcomes were compared among the 3 groups, and surgical quality was analyzed with descriptive statistics. Results Surgical failure rate was 6.7% (10/150). There was no in-hospital mortality. Aortic cross-clamp time, cardiopulmonary bypass time and duration of mechanical ventilation, duration of ICU stay, duration of hospital stays of the group C were significantly shorter than those of the group A and group B. Analysis showed a significant learning curve effect in totally thoracoscopic cardiac surgery. When surgical cases reached about 100 cases, cardiopulmonary bypass and aortic cross-clamp time was shorter than the average value stably. Conclusion Totally thoracoscopic cardiac surgery is safe and reliable. For the beginners, it needs about 100 patients of surgery to master the totally thoracoscopic cardiac surgery.
To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0.01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.
