Abstract
The study included 24,516 newborns who were born between 2007 and 2011 in Louisiana and failed initial hearing screening tests prior to hospital discharge. Unadjusted and adjusted log-linear models were conducted to estimate crude and adjusted annual percent change of rates in loss to follow-up. Besides trends analyzed from 2004 to 2011 in all races, trends were analyzed by race/ethnicity and time periods before and after 2007. Overall, the rate of loss to follow-up was around 50% from 2004 to 2006. It dropped to about 35% in 2007 and kept stable until 2010, and then dropped to 27% in 2011.
