OBJECTIVE:To evaluate evidence situation and implementation of global national drug policies on rational pediatric drug use,and to provide decision-making reference for setting up national drug policies for rational pediatric drug use which adapt to the situation of China.METHODS:By retrieving domestic and foreign related database,scanning drug management websites of WHO,the European Union as well as many countries and regions.A pre-designed data extraction form was used to collect information of the policies of rational pediatric drug use.The information was summarized and analyzed.RESULTS:A total of 45 literatures were included,involving WHO and the European Union,the United States,Canada,Britain,Ireland,Holland,Germany,Spain,France,Australia,New Zealand,China,India,Korea,Japan,South Africa and many other countries and regions.The main points of concern for the national policies of rational pediatric drug use in all countries included promoting the development of clinical trials of children's drugs,formulating and promoting essential medicine list for children,formulating and promoting standard treatment guideline of national pediatric formulary,etc.,and promoting pediatric drug monitoring after the listing.The United States,the European Union and Japan had enacted national laws and regulations on pediatric drug clinical trials;WHO,South Africa and India had developed pediatric essential medicine list;WHO,Britain and China had established pediatric formulary.CONCLUSIONS:It is suggested that the relevant departments should refer to the experiences of the United States and the European Union and other countries and regions to establish national drug policies which adapt to pediatric disease burden and drug use in China

OBJECTIVE:To systematically review the efficacy and safety of anti-vascular endothelial growth factor(VEGF)in-hibitors in the treatment of retinopathy of prematurity (ROP),and provide evidence-based reference for clinic. METHODS:Re-trieved from PubMed,EMBase,Cochrane Library,CJFD,VIP,CBM and Wangfang Database,randomized controlled trials (RCT) about VEGF inhibitors (test group) versus laser photocoagulation treatment (control group) in the treatment of ROP were collected. Meta-analysis was performed by using Rev Man 5.1 software after data extraction and quality evaluation by Cochrane re-viewers manual 5.1.0. RESULTS:Totally 5 RCTs were included,involving 381 infants and 754 eyes.Results of Meta-analysis showed that the recurrence rate of ROP [RR=0.23,95%CI(0.13,0.42),P<0.001],retinal detachment incidence [RR=0.27,95%CI(0.14,0.51),P<0.001] andresolution of plus signs [MD=-1.31,95%CI(-1.47,-1.14),P<0.001] in test group were signifi-cantly lower than control group,the differences were statistically significant;and there was no significant difference in the refrac-tive errors and the incidence of adverse reactions in 2 groups(P>0.05). CONCLUSIONS:Intravitreal VEGF inhibitors have better efficacy than laser photocoagulation in the treatment of ROP,but the optimal dose and safety need further verification by large-sam-ple and well-designed RCT.

OBJECTIVE: To evaluate evidence-based guidelines of current global pediatric idiopathic thrombocytopenic purpura (ITP) drug therapy, and to provide evidence-based reference for pediatric ITP diagnosis and treatment, the formulation of guideline in China. METHODS: Retrieved from PubMed, Embase, National Guideline Clearinghouse, Guidelines International Network, TRIP medical database, CBM, CJFD, VIP and WANFANG DATA, etc., the evidence-based treatment guideline involving pediatric ITP were included, and methodological quality of the guideline was evaluated by using AGREE Ⅱ tool. The similarities and differences of the guidelines were analyzed and compared. RESULTS: A total of 7 pediatric ITP evidence-based guidelines were included, among which 2 came from US, 2 came from Italy, 2 came from British and another one came from Malaysia. The quality of 7 guidelines were not good, among which 6 guidelines were recommended as grade B and 1 guideline was recommended as grade C; only one GRADE evidence-based guideline was found. The score of included guideline in the field of AGREE Ⅱ was in descending order as scope and purpose, clarity, rigor of development, stakeholder involvement, applicability, editorial independence. The main recommended drugs of these guidelines were: glucocorticoids, intravenous immunoglobulin, anti-D-immunoglobulin, while some guidelines recommend platelet, rituximab and combined medication. CONCLUSIONS: The quality of evidence-based guidelines of ITP for children is in low level and should be improved. There is no evidence-based guideline of ITP for children in China. It is suggested to develop high quality evidence-based guideline for ITP children in China based on AGREE Ⅱ items.

OBJECTIVE:To provide reference for the proper understanding of the content of"Access to Essential Medicine"resolution proposed by China at the 67th World Health Assembly(WHA),policy making and implication of the resolution in Chi-na.

OBJECTIVE:To provide evidence-based basis for the continuous improvement of antibacterial use surveillance in China.METHODS:Retrieving from 3 biomedical literature databases as Medline,Embase,Cochrane Library,48 health administrative departments and academic institutions,relevant literatures on antibacterial surveillance networks/ projects were acquired and extracted,including basic information,data collection,analysis and reporting methods,etc.Descriptive analysis method was adopted to analyze the status quo of global antibacterial surveillance networks/projects.RESULTS:A total of 21 literatures were included,involving 16 antibacterial surveillance networks/projects.Among them,there were 3 international projects and 13 national projects,mainly in European (countries) (56.25％,9/16).Sixteen antibacterial surveillance networks/projects were established to monitor and compare the use of antibacterials,analyze the antibacterial use trend and its correlation with bacterial resistance,and evaluate implementation effect of antibacterial management policy.The responsible agencies were mainly the health administrative departments,and the funding agencies were mainly related government departments.Hospital and community were main surveillance objects.There were 2 surveillance networks/projects for antibacterial use in children,and 6 surveillance networks/projects contained medication data of children.Only Strama in Sweden alone analyzed medication data in children.Fourteen surveillance networks/projects promulgated data collection methods or contents;data collection was mainly based on active reporting and involved the data of drug use/consumption and population/ patient.Except for ESAC-Net,ARPEC,NAUSP,data validation method was not mentioned in other surveillance networks/projects.Data analysis was most common in medical institutions and antibacterial categories,and defined daily dose was the most commonly used statistical indicators of antibacterial consumption.Ten surveillance networks/projects promulgated surveillance reports which were mostly published annually.CONCLUSIONS:Antibacterial surveillance have been widely operated worldwide.But there is a lack of monitoring and analysis of antibacterial use in special population including children.In addition,data validation is the weak link of antibacterial surveillance,so the quality of data collection still need to be improved.

OBJECTIVE:To systematically evaluate the monitoring system for global short drugs,and provide evidence-based reference and policy recommendations for developing the short drug monitoring in China. METHODS:Relevant literatures pub-lished in PubMed,Embase,CNKI,Wanfang,VIP database from building to Apr. 3rd in 2017 were retrieved by using"Drugs (cheap drugs,essential medicines,emergency drugs) storage""Short drugs""Insufficient supply of drugs""Drug shortage"as Chinese keywords,and"Drug storage""Out-of-stock drug""Stortage of medicine""Stock out of medicine"as English keywords. Literatures about monitoring system for short drugs in Baidu,Google and national or regional health administration websites were collected,and general information,data collection,data validation,data reporting method,feedback and improvement measures of monitoring system were extracted. RESULTS & CONCLUSIONS:Totally 25 literatures were included,20 national or regional health administration websites were retrieved. 11 countries and European Union had established monitoring system for short drugs. The main reporting agencies in each country were different,which were production enterprises,business enterprises and medical in-stitutions. It was mainly reported by network. Data validation was mainly conducted by specialized departments or groups for short drugs in each country. The monitoring reporting included information of short drugs and discontinued drugs. Countermeasures in each country mainly included looking for alternative drugs,encouraging production,temporary import,looking for new or other sources of raw materials and speeding up the approval of short drugs. Besides, precautions included implementation relevant laws and guidelines for short drugs,and increasing the cooper-ation with non-government departments,etc. Monitoring sys-tem for short drugs needs to be further improved in China. Itis suggested to establish monitoring and early warning platform for short drugs,and hierarchical intervention mechanism,improv-ing relevant laws and developing guidelines on managing short drugs.

OBJECTIVE:To evaluate the global existed diarrhea guidelines of children,and provide evidence and methodology reference for clinical practice and the formulation of diarrhea evidence-based guideline of children in China. METHODS:Retrieved from PubMed,Embase,CBM,CNKI,VIP,Wanfang databases and related websites,references included in studies were retrieved additionally from database building to Dec. 2017. The methodological quality of the guideline was evaluated by 2 researchers independently with guideline evaluation toolⅡ(AGREEⅡ). ICC analysis was used to calculate the differences between the evaluation results of 2 researchers and analyze the difference of the guidelines. RESULTS:A total of 1 168 literatures were collected primarily, and 15 guidelines were involved finally,among which 3 guidelines were from USA,2 from British,2 from WHO,each one from Italy,Europe,India,Australia,Malaysia,New South Wales,South Africa and China,respectively. Of 15 guidelines,there were 10 evidence-based guidelines and 5 non-evidence-based guidelines;evidence levels of guidelines and the method of recommendation intensity were different. ICC of 2 researchers were higher than 0.75(P<0.05),indicating good homogeneity among them. The quality of 15 guidelines were not high enough,and the scores of included guidelines in the field of AGREEⅡin descending order were as follows:scope and purpose(84.44%),clarity of presentation(79.82%),stakeholder involvement(45.74%), rigor of development(41.18%), editorial independence (36.39%)and applicability(33.89%). Main prevention and treatment method recommended by guideline included that(1) prevention and treatment of dehydration was the key link in the treatment of children's diarrhea;(2)guidelines generally believed continuous breastfeeding during rehydration could reduce the risk of dehydration in children;(3)zinc preparation was recommended to shorten the course of diarrhea;(4)antibiotics were used rationally, etc. CONCLUSIONS:The quality of global existed diarrhea guidelines of children should be improved. There is no comprehensive diarrhea evidence- based guideline of children in China,and there is a large discrepancy between the situation of pediatric diarrhea therapy in China and WHO standard;it is urgent to establish a standard treatment. It is suggested to formulate high quality pediatric diarrhea guideline in accordance with the national conditions of China,based on standards for international guideline report, comprehensively considering disease burden and characteristics of pediatric diarrhea in China.

OBJECTIVE： To establish the management system for off-label drug use in a medical institutions， and to standardize the behaviors of off-label drug use and improve the rational drug use. METHODS： Based on evidence-based researches for off-label drug use， management system of off-label drug use was established in our hospital， and off-label drug use management was carried out. The effects of management system were evaluated with the number of records for off-label drug use and pass rate of approval as indexes. RESULTS： Since the year of 2011， the management system for off-label drug use had gradually established and improved in our hospital； the mode of registration and approval for off-label drug use was established by based on a multi-disciplinary team management and quality classification for clinical evidence. Up to 2016， a total of 252 records for off-label use were submitted， among which 159 （accounting for 59.77％） were for pediatrics and 93 （accounting for 34.96％） were for gynecology and obstetrics. Among the submitted records， 181 had passed the examination and approval， and the pass rate was 64.29％. Special prescription comments indicated that the numbers of off-label use medical orders in inpatient medical orders showed a downward trend， and the proportion of recorded medical orders of off-label use had increased from 17.33％ in 2013 to 84.00％ in 2016. CONCLUSIONS： The management system for off-label drug use in medical institutions can effectively improve the clinical understanding of off-label drug use， standardize the behavior of off-label drug use.

OBJECTIVE： To descriptively analyze the status quo of medication therapy management （MTM） at home and abroad， and to provide reference for the development of MTM in China. METHODS：Retrieved from PubMed， Embase， Cochrane Library， CNKI， VIP， Wanfang database， CBM，and simultaneously searched Google and Baidu， retrieve time from the database establishment to March 2019， Chinese retrieval words： “medication therapy management”， English retrieval words： “Medication therapy management” “Management”“Medication therapy”“Therapy management”“Medication”“Drug therapy management”， etc. Domestic and foreign MTM literatures were included. Descriptive analysis was conducted in terms of literature publication， research type distribution， disease distribution and the status quo of MTM literatures in women and children. The necessity and feasibility of MTM in the field of women and children were analyzed. RESULTS & CONCLUSIONS： A total of 403 MTM related literatures （344 foreign， 59 domestic） were included. Among them， the foreign MTM literatures had 154 secondary researches and 190 original studies， clinical value， economic value and humanistic value of MTM were studied in repsects of service providers， service objects， service processes， service effects and other parties. Domestic MTM literatures had 37 secondary researches and 22 original researches， which mainly introduced the US MTM， including implementation background， concept， elements， application status， etc.； the significance and prospects of MTM in China were analyzed. Domestic and foreign MTM literatures mostly focused on chronic diseases in the elderly， mainly endocrine and cardiovascular diseases， such as hypertension， diabetes， and kidney disease. 11 studies about women and children MTM were included （women 5 studies and children 6 studies）； 4 of them were review， 5 were cross-sectional studies， and 2 were case reports. The effects of women and children MTM were introduced in the included literatures from the times of interventions， the number of drug-related problems prevention or improvement， the patient’s clinical outcomes， etc. MTM studies have great differences between at home and aboard in terms of the number of literatures， research types and contents. The researches focus on the field of chronic diseases in the elderly， and there is little literature on MTM in the field of women and children. It is necessary to provide MTM services for women and children in the light of the Millennium Development Goals proposed by the United Nations and the increasing problem of women and children medication. It is suggested to use the MTM model to develop women and children chronic disease pharmaceutical service so as to promote the transformation of pharmacists and improve the quality of pharmaceutical care.
