Objective To investigate the situation of supplemental drugs to the national essential medicines list (EML) in primary health care facilities. Methods Supplemental essential medicine lists published by provincial governments around our country were identified. Characteristics of categories, names and quantities of the supplemental drugs were extracted and compared. Results Supplemental lists issued by 13 provinces were included. The number of the supplemental drugs of four provinces including Jiangsu, Guangdong, Inner Mongolia and Shandong surpassed 200. All the included lists contained chemicals and traditional Chinese medicine, as well as nine categories mentioned in the EML. The frequency of 17 drugs in the supplemental lists was over 10. Specific paediatrics drugs and antitumor drugs were considered by several provinces. Conclusion At present, EML cannot meet the requirements of the primary healthcare. Selection and amendment of EML may refer to the supplemental lists which reflect the demands of essential drugs in every area in our country.
ObjectivesTo introduce the formulating methods and implementing steps of search strategy of systematic reviews (SRs)/meta-analysis (MAs) of animal experiments, so as to provide a reference for domestic related researchers, and promote the development and implementation of high quality SRs/MAs of animal experiments in China. MethodsPubMed, EMbase and CNKI databases were searched online to retrieve studies on the search strategy of SRs/ MAs of animal experiments from inception to October 2017. A descriptive analysis was then conducted using the evidence-based medicine theory and method.ResultsA total of 5 studies were included. The 5 basic steps on how to design and carry out comprehensive search strategies to identify potentially relevant animal experiments on a specific research question were as follow: 1) Formulate research question; 2) Identify appropriate databases and sources of studies; 3) Transform research question into search strategy; 4) Collect search results and remove duplicates; 5) Identify potentially relevant papers. The report of search strategy needs to state its search method and search results clearly.ConclusionThese 5 steps can provide an effective method, which will assist researchers in performing a comprehensive literature search.
