科研试剂耗材与疾病控制能力建设相关性分析

Correlation analysis of scientific research resource consumption and the capability of disease control in a disease control and prevention agency

目的通过对科研试剂耗材的使用情况进行分析,探讨其与疾病预防控制能力建设的相关性,为疾控系统科研试剂耗材的合理购置和有效利用提供参考依据。方法采用描述性研究方法,对中国CDC传染病预防控制所2008-2015年的科研试剂耗材购置及使用情况予以描述,并对其与疾控能力建设进行相关性分析。结果2008-2015年国产和进口试剂耗材分别占试剂耗材购置总金额的21.90%和78.10%。国产试剂和进口试剂比率为0.30,国产耗材和进口耗材比率为0.23。试剂耗材与科研项目、论文发表存在正相关关系(r=0.764、0.712,P<0.05),而与教育培训人数差异无统计学意义(r=0.008,P>0.05)。进口试剂的阳性检出率为87.39%(298/341),国产试剂为70.97%(242/341),差异有统计学意义(χ~2=49.190,P<0.001)。试剂耗材月使用费呈季节性规律性变化,1-2月和8-9月为各年度试剂耗材使用费低谷,12月达全年使用金额最高峰。结论目前科研试剂耗材仍以进口产品为主,6、12月是试剂耗材的使用高峰,试剂耗材的合理购置有利于促进和提高疾控能力建设,以满足疾病控制及相关科研工作的需要。

Objective To provide evidence for an efficient and productive acquirement of scientific research resources in disease control system, and to elucidate patterns in supply orders and disease control capability. Methods The laboratory consumable orders and regulation data were collected from China CDC from 2008 to 2015. Descriptive analysis and correlation analysis were used to discover the influence of laboratory reagent consumable materials on disease control ability. Results We found that during the eight years, domestic reagent supplies accounted for 21.90% of all reagents supplies, while imported reagent supplies accounted for 78.10%. The ratio of domestic and imported reagent was 0.30, and domestic and imported supplies ratio was 0.23. There was a positive correlation between reagent consumables and research outputs such as scientific publications. The correlation coefficients were 0.764, 0.712, P〈0.05. Conclusion Most the laboratory reagents used in the study period was imported. The peaks of consumption were in June and December. Rational purchase of reagent supplies could promote the construction of disease control system, and contribute positively to the disease control management.
