ObjectivesTo systematically review the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, CBM and WanFang Data databases were electronically searched to collect clinical studies on the efficacy of prophylactic antimicrobial use on preventing infections after arthroscopy from January 1990 to September 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using RevMan 5.3 software and Stata 15.0 software.ResultsA total of 8 retrospective cohort studies and 1 randomized controlled trial involving 60 136 subjects were included. The results of the meta-analysis showed that: there was no difference in the post-operational infection rate among patients with and without antimicrobial prophylaxis for arthroscopies (OR=0.51, 95%CI 0.25 to 1.04, P=0.06). For knee arthroscopies, the post-operational infection rate had no difference between patients with and without antimicrobial prophylaxis (OR=0.89, 95% CI 0.65 to 1.23, P=0.48). However, for shoulder arthroscopies, the post-operational infection rate in the antimicrobial prophylaxis group was significantly lower than that in the group without the antimicrobial prophylaxis(OR=0.18, 95%CI 0.08 to 0.37, P<0.000 01).ConclusionsCurrent evidence shows that there is no association between preoperative antimicrobial prophylaxis and a decreased infection rate for knee arthroscopies. Antimicrobial prophylaxis appears to lead to fewer infections after shoulder arthroscopies. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.

This paper mainly introduces the implementation of qualification documents audit in West China Hospital, Sichuan University, including system construction, process reengineering, documents audit scope and key points, and document management.
ObjectiveTo explore the personalistic characteristics of patients with migraine and medication-overuse headache (MOH), and to provide scientific evidence for mental treatment of these patients. MethodsThe subjects were divided into three groups:migraine group, MOH group, and health group.Patients with migraine or MOH, admitted to the Deyang People's Hospital from March 2012 to March 2014, were selected in this study.In addition, healthy volunteers were selected as controls at the same time.Data were collected through the Minnesota multiphasic personality inventory computer testing software, and differences of personalistic characteristics were compared among patients with migraine, MOH and controls. ResultsPatients with migraine and MOH had mental problems and the occurrence rate of psychological problems of MOH patients was significantly higher than that of migraine patients (χ2=6.055, P=0.014).Migraine patients showed higher scores of hypochondriasis, depression, hysteria, psychasthenia, hypomania than controls (P < 0.01).Compared with migraine patients, the scales of hypochondriasis, depression, hysteria, paranoia, schizophrenia were higher in MOH patients (P < 0.01). ConclusionsPatients with migraine and MOH have personalistic and psychological problems.Early screening of personalistic characteristics and mental interventions may improve the clinical outcome of patients with migraine or MOH.
ObjectiveThis study aims to compare different references for the fetal risk of drugs used in pregnancy to provide evidence for the safety of drug use in pregnancy.MethodsFour drug databases, including Lexicomp, Micromedex, TERIS, and Reprotox, as well as two books of drugs in pregnancy edited by Briggs and Schaefer, were searched. Descriptive analysis was performed regarding the definition of pregnancy recommendations and the specific content of medication.ResultsThe six references employed slightly different approaches to drugs in pregnancy, however, all of them included summaries of the risk in pregnancy, data of crossing the placenta, and human and animal data. The databases of Micromedex, TERIS, and a book edited by Briggs had their risk classification systems for drug use during pregnancy. For specific drugs, the summary of different information in pregnancy was different, the amount and content of listed evidence varied, and there was no evaluation of the quality and relevance of evidence among the references.ConclusionsThere is no consensus on the risk assessment of drugs in pregnancy. Risk classification systems for drugs in pregnancy are still an important method for determining the fetal risk of drugs. The existing references merely list studies of drugs in pregnancy, without comprehensive quality assessment. A methodological study of assessment of the risk of drugs in pregnancy is required.
Objective To explore the serious situation of injection abuse, and its influence to average prescription fee. Methods The subjects of this study were health service settings in rural area of 9 provinces/cities in Midwest of China. The treatment prescription indicators of county and village health service settings were calculated. Results Prescription injection rates of health care facility in rural area of Midwest provinces/cities of China (25.8% to 62.2%,mean: 45.1%) were higher than the standard of WHO (13.4% to 24.1%), and the injection abuse situation was serious. Injection bause caused the increase of prescription fee. Excess usage of injection in health service settings was related to the economic level of the on-site county or village, and also related to the size and load of health service facilities. Conclusion Suggestions are proposed to the government health agency according to the results of the study: enhancing the lawmaking, establishing the related policy and effective measure, training the medical personnel, promoting the mass health education, investigating the effective injection management model in rural area, and reducing the rate of injection.
Objective To explore the relation between stigma and substance use of patients with substance use disorder and explore the impact of learning addiction medicine massive open online course (MOOC) on patients’ stigma, depression and anxiety. Methods Patients with substance use disorder in Meishan Detoxification Center from January 11 to 18, 2020 were selected. The patients were randomly divided into control group and teaching group. Both groups participated in regular labor reform while the teaching group attended extra MOOC course. The general demographic data and the duration and amount of substance use were collected before intervention. Before and after intervention, all the patients completed scales including Chinese Version of Substance Use Stigma Mechanisms Scale (SUSMS-C), Zung Self-Rating Depression Scale (SDS) and Zung Self-Rating Anxiety Scale (SAS). The correlation between stigma and depression, anxiety, substance use characteristics were analyzed, as well as the changes of stigma, depression and anxiety before and after MOOC intervention.Results A total of 78 patients were included, including 41 in the control group and 37 in the teaching group. There was no correlation between the scores of SUSMS-C and the duration or amount of substances use (P>0.05). SAS score and SDS score were positively correlated with the total score of stigma, internalized stigma, enacted stigma (family) and enacted stigma (healthcare providers) (P<0.05). SDS scores and SAS scores had no correlation with the anticipated stigma (P>0.05). After intervention, the total score of stigma, anticipated stigma (family) and anticipated stigma (healthcare providers) in the teaching group decreased (P<0.05). In the control group, only anticipated stigma (family) decreased (P=0.047). There was no significant difference in other SUSMS-C items, SAS scores, or SDS scores between the two groups before and after intervention (P>0.05). Conclusions Stigma may not be able to protect patients with substance use disorder from using substances. Instead, stigma may potentially cause negative emotional consequences like depression and anxiety. The addiction medicine MOOC can be used as an intervention to reduce the stigma of patients with substance use disorder.

ObjectiveTo investigate the effects of antimicrobial management program on inpatients outcomes and antimicrobial resistance among clinical isolates in a large-scaled university hospital.MethodsThe antibiotics use density (AUD) and antimicrobial resistance rate of multi-drug resistant bacteria before (from January 2009 to December 2010) and after (from January 2012 to December 2016) the intervention of antimicrobial management program in a large-scaled university hospital (4 300 beds) were calculated and compared, and the correlations of AUD with average length of hospital stay and mortality rate were analyzed.ResultsThe AUD was significantly decreased after intervention (P<0.001). The resistance rate of Staphylococcus aureus to oxacillin decreased (P<0.001). Among Gram-negative bacteria, the resistance rates to carbapenems in Acinetobacter baumannii (P<0.001) and Klebsiella pneumoniae increased (P=0.011). AUD was not correlated with the average length of hospital stay (P=0.644), while positively correlated with the in-hospital mortality rate (r=0.932, P=0.001).ConclusionsThe implementation of antimicrobial management program can significantly reduce the antimicrobial use and do not worsen patient outcomes in the hospital. The impact of the program on resistance varies significantly depending on both the bacterium and the agent, and carbapenem-non-susceptible Gram-negative bacilli emerges as a major threat. It is still necessary to combine other infection control measures.
The development of evidence-based clinical practice guidelines is a sophisticated and systematic process, often requiring multidisciplinary efforts. The traditional approach to developing and updating clinical practice guidelines is usually time-consuming. These limitations obstacle the effective use of guideline recommendations and efficient transformation of most recent research evidence into practice. The MAGIC system is a novel method system for rapid creation and dissemination of high-quality clinical recommendations, including rapid creation of trustworthy recommendations, thus ensuring the scientific and efficient production of clinical practice guidelines; facilitating rapid dissemination and dynamic updating of clinical practice guidelines through recommendation release system (i.e., MAGICapp); and helping promote the production of relevant high-quality original research evidence by identifying the insufficiency of evidence in the process of creation of guideline recommendations. Ultimately, a complete closed-loop digital and trustworthy evidence ecosystem is developed. In order to further promote the effective transformation of research evidence into guideline recommendations, MAGIC China Center was established. We anticipate that the Center will assist the further development and effective use of clinical practice guideline in China.
Objective To investigate the difference of anticoagulant efficacy of heparin and citric acid during continuous renal replacement therapy (CRRT) in patients with severe acute pancreatitis, and analyze their effects of on filter life span, length of hospital stay and mortality. Methods Patients with severe acute pancreatitis in Intensive Care Unit of the First Affiliated Hospital of Hebei North University between January 2018 and July 2022 were retrospectively enrolled, and they were divided into heparin group (control group) and citric acid group (research group) according to anticoagulation methods. The differences of anticoagulant catheter blockage during CRRT, filter life span, length of hospital stay, and 90-day mortality between the two groups were analyzed. Results A total of 108 patients were enrolled, including 56 in the research group and 52 in the control group. In pre-CRRT treatment, the balance value of fluid intake and outflow in the research group was significantly lower than that in the control group (P<0.05). The 108 patients received 217 times of CRRT treatment totally, with a median length of treatment of 63 h (range 44-87 h). The severity of catheter blockage in the research group was lower than that in the control group (P=0.003). The filter life span was longer in the research group than that in the control group [42.5 vs. 29.0 h; hazard ratio=1.83, 95% confidence interval (1.23, 2.73), P<0.001]; in the comparison of 90-day mortality, there was no significant difference between the two groups (P>0.05). The mean use of filters in the research group was less than that in the control group (1.93±0.09 vs. 2.17±0.14, P<0.001). The downtime of CRRT due to filter life in the research group was obviously shorter than that in the control group [120 (0, 720) vs. 300 (0, 890) min, P=0.029], while the duration of CRRT in the research group was remarkably better than that in the control group [10.6 (4.9, 27.7) vs. 8.1 (3.6, 25.0) d, P=0.024], and the risk of filter replacement due to special conditons in the research group was lower than that in the control group (46.4% vs. 65.4%, P=0.048). There was no statistically significant difference in the length of intensive care unit hospitalization or total hospitalization between the two groups (P>0.05). Conclusion Both heparin and citric acid could assist the treatment of CRRT, while citric acid might be apt to improve local coagulation and systemic inflammatory response.
