Community Health Worker Intervention for Newborns Not Passing Initial Universal Hearing Screening

Background: Universal newborn hearing screening (UNHS) is effective in identifying newborns with possible hearing loss (HL). Outpatient follow-up for newborns referred after hospital-based screening remains a potential area of improvement. In this study, we evaluate the efficacy of a community health worker (CHW) intervention in promoting adherence to outpatient rescreening for newborns referred after initial UNHS. Methods: A mixed prospective-retrospective cohort study was performed to evaluate a CHW intervention at an academic medical center. Caregivers of referred newborns were contacted by CHWs prior to discharge and educated about HL and the importance of follow-up screening. The CHW outreach intervention was performed for 297 referred newborns between May 2020 and June 2021 and compared to a cohort of 238 newborns without the CHW intervention between March 2019 and June 2021. Statistical analyses were conducted using 2 x 2 Chi-square tests, two-tailed unpaired t-tests, multinomial logistic regression, and multiple linear regression. Results: In the intervention group, 236 of 297 newborns (79.5%) completed their outpatient follow-up rescreening; in the comparison group, 170 of 238 newborns (71.4%) completed their follow-up rescreening (P =.031, OR = 1.55 with regression P =.04). In the intervention group, the average time to follow-up was 13.4 days versus 12.5 days for the comparison group (P =.449, multiple R-2 =.02 with P = .78). Conclusions: CHW outreach intervention may increase adherence to outpatient follow-up rescreening for newborns referred after initial, hospital-based UNHS. Expansion of nursery teams to include CHWs may thus improve completion of recommended follow-up hearing screens.
