Early childhood expulsions are a systemic issue in early care and education (ECE) that have negative consequences for children, families, ECE programs, and communities. The Ohio Preschool Expulsion Prevention Partnership (OPEPP) represents one state's attempt to reduce the incidence of early childhood expulsions using infant and early mental health consultation distributed statewide in a hub-and-spoke arrangement. The study merges records from the first four years of OPEPP implementation (N = 569 expulsion prevention referrals) with child care licensing data (N = 3408 ECE programs) and data from the American Community Survey to assess OPEPP's reach in both the hub and spoke regions and identify what program and community characteristics were associated with OPEPP uptake. We found that 16.7 % of center-based ECE programs operating in Ohio between April 2016 and December 2019 participated in OPEPP, but distribution of referrals was uneven, with 36 % of ECE programs in the hub participating but just 10 % of programs outside of the hub doing so. ECE programs with higher quality ratings had greater odds of participating in OPEPP, as did ECE programs outside of the hub area that accepted publicly funded child care reimbursements. The differences in participation rates and predictors of participation between the hub and spoke regions suggest a need to explore how the hub-and-spoke arrangement of OPEPP may need to be adjusted to reach ECE programs outside of the hub region more effectively and have implications for other large-scale early childhood expulsion prevention efforts.

幼儿开除是早期保育和教育 (ECE) 中的一个系统性问题，对儿童、家庭、ECE 项目和社区产生负面影响。俄亥俄州学前班开除预防合作伙伴关系 (OPEPP) 是一个州尝试通过在全州范围内分布的婴儿和早期心理健康咨询来减少幼儿开除发生率的尝试。该研究将 OPEPP 实施前四年的记录（N  = 569 例驱逐预防转介）与儿童保育许可数据（N  = 3408 个 ECE 项目）以及美国社区调查的数据相结合，以评估 OPEPP 在中心和辐射区域的影响力并确定哪些计划和社区特征与 OPEPP 的采用相关。我们发现，2016 年 4 月至 2019 年 12 月期间，在俄亥俄州运行的中心 ECE 项目中有 16.7% 参与了 OPEPP，但转介分布不均匀，中心内的 ECE 项目有 36% 参与，但中心外的项目只有 10% 参与。枢纽这样做。质量评级较高的 ECE 项目参与 OPEPP 的几率更大，中心区域之外接受公共资助的儿童保育报销的 ECE 项目也是如此。中心区域和辐射区域之间参与率和参与预测因素的差异表明，需要探索如何调整 OPEPP 的中心辐射安排，以更有效地实现中心区域之外的 ECE 项目，并对其他大规模的幼儿期驱逐预防工作。
