Abstract
OBJECTIVE: Maternal hepatitis C virus (HCV) infection reported on birth certificates has been shown to underestimate HCV infection. We sought to determine the usefulness of HCV surveillance data for (1) quantifying the number of HCV-positive reproductive-aged women with a live birth, (2) comparing maternal HCV surveillance data with reported HCV infection status on birth certificates, and (3) delineating past versus current maternal infection to identify true perinatal exposures. METHODS: We extracted data from January 1, 2013, through December 31, 2017, on birth certificate indication of HCV exposure from the Tennessee Birth Statistical File, and we ascertained indication of HCV exposure by using laboratory data from the Tennessee National Electronic Disease Surveillance System (NEDSS) Base System (NBS). We conducted a sensitivity analysis comparing birth certificate indication of HCV exposure with HCV laboratory data to determine whether true perinatal exposure had occurred. RESULTS: During the study period, 6731 mothers with live births in Tennessee reported having HCV infection during pregnancy: 3295 (49.0%) had both laboratory and birth certificate indication of HCV infection, 2130 (31.6%) had indication of HCV infection on the laboratory report only, and 1306 (19.4%) had indication of HCV infection on the birth certificate only. CONCLUSIONS: Using data from a public health HCV surveillance system with birth certificate data may improve the identification of HCV-infected pregnant women and perinatally exposed infants. Surveillance systems that include complete reporting of all HCV RNA results can be used to distinguish past from present maternal HCV infection to focus limited public health resources on currently infected mothers and their exposed infants.
