CDC's National Center on Birth Defects and Developmental Disabilities funded a pilot project to develop and implement population-based surveillance of confirmed newborn screening conditions using existing data collection systems in 4 U.S. states. Long-term follow-up outcomes were collected on each child through their third birthday. The purpose of this thesis is to examine the data completeness of the long-term follow-up data collected through the pilot project. Over three years of follow-up, 261 metabolic cases were identified in 1,343,696 live births. The primary outcome of this analysis is the percentage of completeness for each variable (number of observations with data for that variable/total number of observations). The denominator decreases from year 1 to year 3 to exclude those that died or moved out of the catchment area during the previous year. Data completeness was compared across the three types of data collection systems used in four states: 2 active birth defects surveillance systems, 1 passive system with case confirmation, and 1 newborn screening system. A fairly consistent level of completeness was observed across the five types of variables (demographic, diagnosis, service utilization, development, co-morbidities). Of the variables that focused on long-term follow-up outcomes for these children, the service utilization and co-morbidity variables were of the highest quality. The developmental variables showed the most variation in data completeness. The two active systems and the passive with case confirmation system contributed the data with the highest completeness. The NBS system contributed the most number of cases to the cohort and was still able to contribute high quality data.
