Amplitude-Integrated Electroencephalography: A Survey of Practices in the United States

Abstract

Objective Amplitude-integrated electroencephalography (aEEG) is a simplified method for continuous monitoring of brain activity in the neonatal intensive care unit (NICU). Our objective was to describe current aEEG use in the United States.

Study Design An online survey was distributed to the American Academy of Pediatrics Section on Perinatal Pediatrics' list serve.

Result A total of 654 surveys were received; 55% of respondents reported using aEEG. aEEG was utilized more often in academic and levels III and IV NICUs; hypoxic-ischemic encephalopathy and suspected seizures were the most common indications for use. aEEG was primarily interpreted by neonatologists (87%), with approximately half reporting either self-teaching or hospital-based training for interpretation. For those not using aEEG, uncertain clinical benefit (40%) and cost (17%) were reported as barriers to use.

Conclusion More than half of neonatologists utilize aEEG, with practice variation by NICU setting. Barriers to wider adoption include education regarding potential benefit, training, and cost.
