Are paediatric clinical practice guidelines trustworthy?

AIM: To assess the methodological and reporting quality of paediatric clinical practice guidelines (CPGs) in National Guideline Clearinghouse (NGC) using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and Reporting Items for Practice Guidelines in Healthcare (RIGHT) standard. METHODS: We identified all published CPGs through the NGC, and search records were screened in duplicate for inclusion. Two researchers evaluated the methodological and reporting quality of paediatric CPGs using the AGREE II instrument and RIGHT standard. STATA version 12.0 and SPSS version 22.0 software were used to analyse the related data. RESULTS: A total of 50 paediatric CPGs were included. The scores for all six domains by AGREE II instrument were presented as follows: scope and purpose (85.6 ± 9.59), stakeholder involvement (69.15 ± 19.32), rigour of development (73.19 ± 17.18), clarity of presentation (78.51 ± 14.36), applicability (54.61 ± 22.63) and editorial independence (68.42 ± 13.06). In the seven domains of the RIGHT standard, the reporting rate of the recommendation domain was the lowest (52.86%).The highest reporting rate was the other information domain, which was 68%.There was a high correlation between reporting the completeness of CPGs using the AGREE II instrument and RIGHT standard (r = 0.77, P < 0.001). CONCLUSIONS: The paediatric CPGs from NGC have good quality. There was a high correlation in the completeness of reporting for paediatric CPGs using the AGREE II instrument and RIGHT standard. It could be concluded that the CPGs of good methodological quality have good reporting quality. Maybe the researcher should effectively combine the AGREE II instrument and RIGHT standard in the development process of CPGs.

[Visual analysis of research theme and capability of real world research].

As a new concept in clinical research,the real world research(RWR) has attracted the attention of researchers in the world with its unique advantages. This research mainly analyzed it through visual methods,the specific steps were as follows. Firstly,the Chinese Biomedical Literature Database,China National Knowledge Infrastructure,Wan Fang Database,Medline and EMbase were searched and RWS were included,414 articles in Chinese and 2 158 articles in English were included in this research after layer-bylayer screening; secondly,the main information was extracted and sorted by BICOMS 2 software and generated its co-occurrence matrix; the network relationship diagram was drawn by Net Draw software; the cluster analysis was carried out by using g CLUTO software;finally,this research results show that the numbers of domestic and foreign literatures have shown an overall growth trend,but compared with foreign countries,China's research on the real world started late,the overall strength of research was not as good as abroad;and the domestic and foreign research on the real world was uneven in the region,the research in China was mainly distributed in developed provinces and cities,such as Beijing,Guangdong,Shanghai,etc,and there was a lack of close cooperation between provinces and cities; the foreign research are mainly distributed in developed countries such as the United States,the United Kingdom,Germany,et al; the cooperation between countries was relatively close. And the hotspots and core directions of domestic and foreign research were also different. This research was intended to provide reference for the further research of Chinese researchers through the current description of the themes and capability of the real world research in the world.
