[Newborn hearing screening in Germany-results of the 2011/2012 and 2017/2018 evaluations]. / Neugeborenen-Hörscreening in Deutschland ­ Ergebnisse der Evaluationen 2011/2012 und 2017/2018.

BACKGROUND: Newborn hearing screening (NHS) was introduced nationwide by the Federal Joint Committee (Gemeinsamer Bundesausschuss, G­BA) in 2009. In this process, quality targets were also set in the pediatrics directive. In order to review the quality NHS in Germany, the G­BA commissioned a consortium to conduct an initial evaluation for the years 2011 and 2012 and a follow-up evaluation for 2017 and 2018. METHODS: The evaluations were based on NHS screening parameters (Sammelstatistiken) that must be documented by all obstetrics and neonatology departments as NHS providers and can also be compiled through cooperation with hearing screening centers (HSCs). Additional data were collected through questionnaires and interviews and routine data were used to evaluate the screening process. RESULTS: In 13 federal states, a total of 15 HSCs are involved in the screening process. Across Germany, an NHS screening rate of 86.1% was documented in 2018 (82.4% in 2012), but this differed significantly between the federal states. The specified quality targets could not yet be implemented everywhere. For example, only less than half of the obstetric departments achieved the specified screening rate of over 95%. A comparison of data from the follow-up evaluation and the first evaluation showed that the structural quality of NHS had improved, while the process quality remained the same or had deteriorated. The refer rate (children who were discharged without passing the screening) increased from 5.3% to 6.0%. DISCUSSION: To improve the quality of NHS, HSCs should be established nationwide and a second screening should be carried out more consistently before discharge in the case of a refer result in the initial screening.

Is Our Newborn Screening Working Well? A Literature Review of Quality Requirements for Newborn Blood Spot Screening (NBS) Infrastructure and Procedures.

Newborn screening using dried blood spots (NBS) is widely acknowledged as a highly successful procedure in secondary prevention. For a number of congenital disorders, severe disability or death are impressively prevented by early detection and early treatment through NBS. However, as with any other screening, NBS can also cause harm, and the principle that "the overall benefits of screening should outweigh the harms" must be considered when introducing and implementing NBS programmes. This publication compiles the results of a systematic literature research on requirements for NBS infrastructure and procedures which was conducted as part of a research project on the quality and shortcomings of the NBS pathway in Germany. The compilation contains the requirements and recommendations for realising the principle of "maximise benefits and minimise harms" in relevant NBS pathway components such as parental education and information, coverage, timeliness, laboratory quality assurance, follow-up of abnormal results, confirmatory diagnostics, documentation, and evaluation. The results reflect the complexity of NBS infrastructure, and thus, they illustrate the importance of considering and implementing NBS as a well-coordinated public health programme with continuous quality management. Special attention should be paid to the perspectives of parents and families. Some NBS issues can substantially benefit from digital instruments or international cooperation. The literature review presented here has contributed to a concept of proposals for the advancement of NBS in Germany, and despite different settings, it may as well be of interest for other countries to achieve the best possible course and outcome of NBS for each child.
