risk of permanent hearing loss who have not been identified in the EHDI
program’s screening and diagnostics.
|
It was calculated using the formula CLEAR / Tscr * 1000. At this time,
the CLEAR metric was calculated using Total Not Pass Last Screening and
may lead to some unexpected results. For example, with South Dakota in
2021. We are reviewing this and a second metric on not passing – Total
Not Pass – that includes babies who were not screened. We will make
adjustments as decisions are made.
