基于Malmquist-数据包络分析法的北京市产前超声筛查服务效率评价

Efficiency of Prenatal Ultrasound Screening Service in Beijing:A Malmquist-Data Envelopment Analysis

目的分析北京市产前超声筛查服务效率情况,为优化北京市出生缺陷二级预防体系提供相应政策依据。方法利用2010~2016年北京市产前超声筛查服务年度报表数据,质控后提取关键变量,基于数据包络分析法计算北京市各区超声筛查服务效率及变化趋势,并探讨城市、远郊地区服务效率差异。结果2010至2016年超声筛查服务的综合技术效率值呈波动增长趋势,远郊地区综合技术效率均值高于城市地区。2010至2016年超声筛查服务的全要素生产率年均提高了12.3%,其中技术变化年均提高了12.0%,综合技术效率年均提高了0.3%,纯技术效率年均提高了13.9%,规模效率年均下降了0.4%。结论2010至2016年北京市超声筛查服务效率有所增加,全要素生产率提高,技术进步和纯技术效率提高是主要推动力。建议北京市应进一步优化资源配置提高规模效率,增加超声筛查专业技术人员的培养。

Objective To analyze the efficiency of prenatal ultrasound screening service in Beijing and thus optimize the secondary prevention system for birth defects in Beijing.Methods Data were collected from the prenatal screening work reports of Beijing from 2010-2016.Key variables were extracted after data quality control.Data envelopment analysis was performed to analyze the efficiency and changing trend of ultrasound-based screening service and to compare the service efficiency between urban and suburban areas in Beijing.Results From 2010 to 2016,the technical efficiency of ultrasound screening services showed an increasing trend,and the geometric mean of technical efficiency in suburban areas was higher than that in urban areas.From 2010 to 2016,the total factor productivity of ultrasound screening service increased by 12.3%annually,in which the technical change increased by 12.0%annually;the technical efficiency increased by 0.3%,the pure technical efficiency increased by 13.9%annually,and the scale efficiency decreased by 0.4%.Conclusions The technical efficiency of ultrasound screening service in Beijing increased from 2010 to 2016,and the total factor productivity improved.Technical change and pure technical efficiency change were the main reasons for the improvement.The resource allocation should be further optimized to improve the scale efficiency and enhance the training of prenatal ultrasound screening technicians.
