目的 了解2015—2022年全国三级妇幼保健院服务提供和利用情况及其变化趋势，为制定妇幼健康政策提供依据。方法 利用全国妇幼保健机构监测系统数据，分析描述2015—2022年全国所有三级妇幼保健院门急诊人次数、出院人次数、活产数、实有床位数和床位使用情况，与来源于《中国卫生健康统计年鉴》中同期全国医疗卫生机构和综合医院的相关数据进行比较。结果 2015年以来全国三级妇幼保健院门急诊人次数和出院人次数总体呈上升趋势，年平均增长率分别为8.0%和7.4%，均高于同期全国医疗卫生机构和综合医院的年平均增长率；三级妇幼保健院活产数占全国总活产数的比例逐年上升；实有床位数逐年增加，年平均增长率为8.6%，但床位使用率由2015年的92.4%下降到2022年的71.3%。三级妇幼保健院的床位使用率高于同期全国医疗卫生机构平均水平和综合医院，但低于同期三级医院的水平。结论 近年来，我国三级妇幼保健院服务提供和利用量整体呈现良好的发展趋势，但需进一步提高服务能力，不断提高床位使用率。

Objective To understand the situation and trends of service provision and utilization in all tertiary maternal and child health care(MCH) hospitals from 2015 to 2022 in China, and to provide a basis for formulating MCH policies and strategies.Methods Using data from the national monitoring system for maternal and child health care institutions, this study analyzed and described the number of outpatient and emergency visits, hospital discharges, live births, actual beds and bed utilization in all tertiary MCH hospitals from 2015 to 2022 in China. The data was also compared with relevant data from national medical and health institutions and general hospitals derived from the China Health Statistics Yearbook during the same period. Results Since 2015, the number of outpatient and emergency patients and discharged patients in the national tertiary MCH hospitals shown an upward trend.The average annual growth rate were 8.0% and 7.4%, respectively, which were higher than the average annual growth rate of national medical and health institutions and general hospitals during the same period. The proportion of live births in tertiary MCH hospitals accounted for the total number of live births in China has increased annually. The number of actual beds increased annually, with an average annual growth rate of 8.6%, but the bed utilization rate in the national tertiary MCH hospitals has decreased from 92.4% in2015 to 71.3% in 2022. The bed utilization rate of tertiary MCH hospitals was higher than the national average level of medical and health institutions and general hospitals during the same period, but lower than that of tertiary hospitals. Conclusion In recent years,the service provision and utilization of tertiary MCH hospitals in China show a good development trend overall, but it is necessary to further improve service capabilities and continuously increase bed utilization rates.
