Study Design: Data from the 2000 - 2005 rounds of the Medical Expenditure Panel Survey are used to assess the performance of a variety of predisposing, enabling, and need measures in predicting health care utilization and expenditures over a one-year period. Specific candidate predictors include parent reports of health and mental health status; the Children with Special Health Care Needs (CSHCN) screener; the presence of enumerated chronic health conditions; health care utilization, including emergency room (ER) visits, inpatient and outpatient utilization within the past year; and access to and satisfaction with the health care system. Multivariate logistic regression models are fitted for the following outcomes: high outpatient and ER visits, operationalized as belonging in the top decile of users, and high annualized total health care expenditures, again operationalized as membership in the top expenditure decile. Models are evaluated using the c-statistic, integrated discrimination improvement, sensitivity, specificity, and predictive values. Model building and testing are performed on different, randomly selected samples.
Population Studied: The analytic sample includes 9,737 children ages 1-17 who are income-eligible for Medicaid or insurance subsidies in the Marketplace (incomes up through 400% FPL).
Principal Findings: Models including the prior year’s utilization and CSHCN domains exceed the standard threshold of predictive acceptability (c- statistic > 0.70) for all three outcome measures. Future analyses will assess the incremental predictive capacity of each of the remaining hypothesized domains in addition to the combined predictive ability across all domains.
Conclusions: Preliminary results suggest that PRH measures are meaningfully predictive of high-need pediatric patients, substantiating their potential use as input data for case-finding purposes when claims data are unavailable.
Implications for Policy, Delivery, or Practice: Our work proposes and tests a novel case-finding approach designed to identify Medicaid- and subsidized Marketplace- eligible children with elevated health care need. Our results suggest that insurers and other stakeholders can administer a simple series of PRH measures as a means to target intensive care management interventions. Compellingly, this method does not require recent claims history, which is particularly beneficial in the context of serving low- and moderate- income pediatric members who experience appreciable levels of insurance churn.
