2017—2019年陕西省不同区域疾控机构水质检测能力现状

Investigation on water quality testing capabilities of disease control institutions in different regions of Shaanxi Province,2017-2019

目的对2017—2019年陕西省不同区域市、县(区)级疾病预防控制中心(以下简称CDC)水质检测能力变化趋势和存在问题进行分析,为实验室能力建设提供参考。方法制定统一的调查表,对陕西省不同区域的所有CDC开展水质检测能力调查,通过“全国饮用水水质卫生检测信息系统”上报数据。结果常规指标中,2017—2019年,市级CDC平均能检测数分别为37、37和38项,均通过了计量认证/实验室认可,县(区)级CDC平均能检测数分别为30、29和30项,只有65.14%的县(区)级CDC通过了计量认证/实验室认可;非常规指标中,市级CDC平均能检测数分别为3、5和4项,县(区)级CDC平均能检测数最多为1项。同一年度不同区域市级、县(区)级CDC平均检测能力差异均无统计学意义(P>0.05);同一区域不同年度市级、县(区)级CDC平均检测能力差异均无统计学意义(P>0.05)。结论陕西省不同区域CDC水质检测水平差异不大且有待进一步提升,建议政府加大对疾控机构的经费投入,优化配置仪器设备,加强专业队伍建设。

Objective To analyze the change in trends and existing problems of the water quality testing capabilities of the Centers for Disease Control and Prevention(CDC)in different cities and counties(districts)in Shaanxi Province from 2017 to 2019,and to provide references for laboratory capacity building.Methods A unified questionnaire was developed to investigate the water quality testing ability of all CDCs in different regions of Shaanxi Province,and the data were reported through the“National Drinking Water Quality Inspection Information System”.Results From 2017 to 2019,in the testing of conventional indicators,the average number detected by the municipal CDCs was 37,37,and 38,respectively,and all of them passed the measurement certification/laboratory accreditation.The average number detected by the county(district)CDCs was 30,29,and 30,respectively,and only 65.14%of the county(district)CDCs passed the measurement certification/laboratory accreditation.In the testing of unconventional indicators,the average detectable number by city-level CDCs was 3,5,and 4,respectively,while the average detectable number by county(district)-level CDCs was at most 1 item.There was no statistically significant difference in the average detection ability of CDCs at the city and county(district)levels in different regions in the same year(P>0.05);there was no significant difference in the average detection ability of CDCs at the city and county(district)levels in the same region in different years(P>0.05).Conclusion There is no difference in the CDC water quality testing level in different regions of Shaanxi Province,and the testing capacity needs to be further improved.It is recommended that the government should increase funding for disease control institutions,optimize the allocation of equipment and strengthen the construction of professional teams.
