WIC Participation as a Risk Factor for Loss to Follow-Up in the Wisconsin EHDI System

Abstract

In 2011, Wisconsin’s Early Hearing Detection and Intervention (EHDI) program, Wisconsin Sound Beginnings (WSB), developed multiple strategies to reduce loss to follow-up (LTFU) for babies who did not pass their newborn hearing screening: Medical Outreach, Family Outreach, Regional Outreach, and WIC Alert. WSB evaluated the outcomes of babies identified as at-risk for LTFU to determine whether WIC participation was an indicator of their risk for LTFU. Additionally, WSB evaluated whether babies who were identified as at-risk for LTFU and receiving WIC services in two WIC projects serving areas and populations with known health disparities, were at even greater risk for LTFU. WSB found no statistically significant differences in outcomes between babies who were WIC participants and those who were not. This paper discusses implications of this research for other EHDI programs.
