Laboratory-Based Evaluation of the Newborn Screening Programme: A 25-Year Retrospective Study.

Abstract

As part of an integrated public health program with centralized coordination, the German federal state of Bavaria introduced newborn screening (NBS) utilizing dried blood spots (DBS). The Bavarian NBS Center works with parents, specialized centers of competence, obstetric and pediatric hospitals, and NBS laboratories. Coordination, assessment, quality control, and a long-term follow-up research fall under its purview. An examination of NBS in Bavaria is provided in this paper, along with a long-term follow-up that was treated early because of NBS. A 99.83% NBS coverage rate was attained, and 99.09% of all repeat tests that were requested were finished. Within the first 14 days of life, over 87% of newborns with time-sensitive illnesses received a therapeutic intervention. Systematic tracking allowed for the timely diagnosis of 122 babies and the clarification of all but 54 NBS-positive results. The long-term follow-up study's findings show that nearly every child found through NBS receives continuing medical care and that NBS has helped the majority of impacted children develop in an appropriate age manner. This 25-year assessment of NBS in Bavaria demonstrates that centralised coordination and continuous collaboration among all stakeholders can lead to nearly universal NBS participation and follow-up of nearly all positive NBS results.
