Recording Obligatory Cortical Auditory Evoked Potentials in Infants: Quantitative Information on Feasibility and Parent Acceptability.
Kevin J Munro, Suzanne C Purdy, Kai Uus and 6 others
PMID 31633599WHAT IT FOUND
Cortical auditory evoked potentials took 27 minutes and were successfully recorded in 95% of infants with normal hearing.
Parents rated the test as highly acceptable. This confirms the procedure is feasible for clinical use, but data on infants with hearing loss are still needed.
Key findings
01The test took approximately 27 minutes, meeting the target of under 30 minutes.
02CAEP data were successfully obtained from 98 of 103 infants (95%), and interpretable results were achieved in 91 of those tested.
03Parents reported high acceptability of the testing procedure, with responses close to the most positive end of the scale.

What it does not show
The study only included infants with normal hearing who passed newborn screening; it did not test infants with hearing loss or those wearing hearing aids. The test was conducted in a specialized research facility with experienced audiologists and a child playworker, which may not reflect the conditions of a busy routine clinic. The choice of electrode location (forehead vs. vertex) was not strictly randomized but influenced by the testers' preference, which could introduce bias. Parent acceptability data came from families with no prior concerns about their child's hearing, so results may not apply to parents of infants with diagnosed hearing loss.

The easy way to misread this
Do not assume this study proves CAEPs are ready for routine use with infants who have hearing loss. The participants all had normal hearing, and the authors explicitly state that data on infants wearing hearing aids are still required.
