A 5-year retrospective cohort study ( 4,178) was conducted to identify trends and outcomes associated with child welfare-involved maternal-infant dyads affected by perinatal substance use in Colorado. Two linked data sources were used: (1) vital records birth and death certificate data on live births between 2013 and 2019 and (2) child welfare data from the Statewide Automated Child Welfare Information System. Data integration and de-identification work was accomplished by the Linked Information Network of Colorado and authorized by state legislation. Two tools were available for identity resolution: (1) the Senzing identity resolution application and (2) SQL queries. Binary logistic regression was used to explore how a birthing person’s demographic characteristics, use of prenatal care, Special Nutrition Program for Woman, Infants, and Children (WIC) enrollment during pregnancy, health of birthing person during pregnancy and delivery, and the newborn’s health at the time of birth related to child welfare removal within the first 60 days. Factors associated with an increased risk of infant removal includeless than adequate prenatal care, lower household income, low participation in WIC, andgreater medical fragility of the newborn. For infants removed from the home, the rate of placement with relatives while in foster care decreased by 15 % (2016–2019) This is a concern as placing children with relatives is shown to promote healthy child development. Findings bring into focus opportunities for prevention, treatment, and support of maternal-infant dyads affected by substance use during the perinatal period and offers insight into early entry points for preventing the need for family separation by child welfare.

受产前物质使用影响的母婴二人中与儿童福利参与相关的风险和保护因素

一项为期 5 年的回顾性队列研究 (4,178) 旨在确定科罗拉多州受围产期物质使用影响的涉及儿童福利的母婴二人组的相关趋势和结果。使用两个链接的数据源：(1) 2013 年至 2019 年间活产的人口动态记录出生和死亡证明数据，(2) 来自全州自动化儿童福利信息系统的儿童福利数据。数据整合和去识别化工作由科罗拉多州链接信息网络完成，并得到州立法授权。有两种工具可用于身份解析：(1) Senzing 身份解析应用程序和 (2) SQL 查询。使用二元逻辑回归来探讨分娩者的人口特征、产前护理的使用、怀孕期间妇女、婴儿和儿童特殊营养计划 (WIC) 的注册情况、分娩者在怀孕和分娩期间的健康状况以及新生儿在出生时的健康状况。出生时间与儿童福利移除相关的前 60 天内。与婴儿被带走风险增加相关的因素包括产前护理不足、家庭收入较低、WIC 参与率低以及新生儿医疗脆弱性较高。对于离开家庭的婴儿，在寄养期间安置在亲戚身边的比率下降了 15%（2016-2019 年）这是一个令人担忧的问题，因为事实证明，将儿童安置在亲戚身边可以促进儿童的健康成长。研究结果使人们关注在围产期受药物滥用影响的母婴二人组的预防、治疗和支持机会，并深入了解通过儿童福利预防家庭分离的需要的早期切入点。
