| Objective:A bibliometric analysis was conducted to expore the characteristic and pattern of published injury prevention research in China from2001to2010. And the quality assessment tool was used to assess the quality of case-control studies, cohort studies, randomized controlled trials of injury prevention, thus providing the evidence for the quality assessment of injury prevention research.Methods:WanFang databases, China Science Literature Network Publish General Storeroom, VIP Chinese Science&Technology Journal Database, Chinese Biomedicine Literature Database, PubMed and Web of Knowledge were used to search the published studies between January1,2001and December31,2010that related to injury prevention of China.A bibliometrics analysis was applied to describe the distribution of published year, literature type, fund type, periodical type, study first author, study design, injury type and population about injury prevention research. Newcastle-Ottawa-Scale (NOS) was used to evaluate the quality of case-control studies and cohort studies of injury prevention research from journal paper, dissertation, conference paper, and the risk of bias assessment tool recommended by the Cochrane-Handbook5.0was used to assess the quality of randomized controlled trials. All statistical analyses were performed in SPSS13.0software package and Excel2003.Results:1. Bibliometrics AnalysisFrom2001to2010, the total numbers of China injury prevention research were2101, and the yearly cumulative numbers of research increased linearly. Journal paper was the main literature type of injury prevention research, accounting for90.6%. The ratio of fund paper was19.4%in injury prevention research, and the journal paper of injury prevention research was the highest which accounted for20.9%.22journals have published20papers or above, accounted for5.3% of the total journals, and published1022papers in sum, accounting for53.7%of the total number of journal papers. The five leading journals, which published the most papers of injury prevention research, were ’Chinese Journal of School Health’,’Chinese Journal of Disease Control&Prevention’,’Chinese Journal of Epidemiology’,’Modern Preventive Medicine’,’Chinese Journal of Public Health’.114core first authors who have posted3papers or above of injury prevention research, accounted for7.3%of the total authors, and posted370papers in sum, which accounting for17.6%of the total number of papers. The main core first authors were Chun-yan GUO, Lei-lei Duan, Liping Li, Hua Li, Chengxing Han and so on. Public health agency, university and medical institution were the main first author institutions, and the public health agency accounted for the largest proportion that was45.0%. Guangdong, Zhejiang, Shanghai, Beijing, Shandong, Jiangsu, Anhui, Hubei province were the leading posting provinces and cities, which all published more than100papers, and published1367papers in sum, which accounting for65.1%of the total national injury prevention research.The descriptive studies were the main study design type, accounting for92.1%. The proportion of case-control studies, cohort studies, randomized controlled trials and quasi-experimental studies were less, especially the cohort studies, which was the least and was just0.6%. Multi-injury was the leading injury type of injury prevention research, accounting for71.6%, of which all injuries had the largest proportion. While, one single injury accounted for20.6%, of which traffic injury had the largest proportion. Children, adolescents, and the whole population were the main study population, accounting for82.1%, of which the children and adolescents had the largest proportion and which was41.9%.2. Quality assessmentAll case-control studies of injury prevention scored higher than5points of the methodological quality, of which the journal paper was the highest. While, the studies scored lower on the item of’ascertainment of exposure’,’non-response rate’and’adequate case definition’.The main methodological quality score of cohort studies were6 points and7points that accounting for92.3%, of which the dissertation was the highest. But the studies scored lower on the item of’assessment of outcome’.All of the randomized controlled trials did not include the information of the ’blind’,’concealment’, and ’free of early termination bias’. Only one randomized controlled trial of journal paper reported that the subjects were randomly assigned, on the item of ’adequate sequence generation’.Conclusion:1. The injury prevention research increased linearly in China, and journal paper was the main literature type. The ratio of fund paper was relatively low.2. Journals published injury prevention research were relatively concentrated.’Chinese Journal of School Health’,’Chinese Journal of Disease Control&Prevention’,’Chinese Journal of Epidemiology’’Modern Preventive Medicine’,’Chinese Journal of Public Health’ and so on were the important professional journals of injury prevention3. The core author group of the injury prevention research had not formed yet. Public health agency was the main posting institutions. The posting regions mainly came from the economically developed regions in eastern and the central areas that have stronger research background.4. Descriptive studies were the major design of injury prevention research. Most of the injury prevention research focused on mutli-injury. Children, adolescents, and the whole population were the main focused population of injury prevention research.5. The methodological quality of injury prevention research was relatively high in case-control studies and cohort studies, while could not be evaluated in randomized controlled trials due to lack of information in more than half of assessment items. |
