Abstract
This study sought to understand the health status of children in foster care; the relationship between their health status and health care utilization; and demographic and placement factors associated with health care utilization. To estimate relationships between health status and health care utilization, this study used electronic health records from 4976 children in foster care seen at a children's hospital in the southwestern United States, 2017 to 2020. An algorithm classified patients' health status as nonchronic, noncomplex chronic, or complex chronic. Descriptive statistics were used to describe patients and utilization. The χ2, Kruskal-Wallis, and pairwise comparison post hoc tests were used to examine relationships between health status and health care utilization. Zero-inflated negative binomial (ZINB) regression further estimated relationships between health status and health care utilization while factoring in demographic and placement characteristics. Within the sample, 35.6% had complex chronic health status. Significant differences were found among health status groups in age, gender, ethnicity, and maltreatment exposure. Both nonparametric pairwise comparisons and the ZINB regression model showed that having complex chronic health was associated with higher utilization of all hospital resources: emergency, admission, primary and specialty care, and various therapies, relative to having noncomplex chronic and nonchronic health. A high percentage of children in foster care had complex chronic health, and these patients used significantly more resources. This study suggests that hospital-based health clinics focused on children in foster care and care coordination may be warranted.
