Telemedicine to Reduce Disparities in the Identification and Treatment of Neonatal Encephalopathy

Not Applicable

Completed

• Conditions: Neonatal Encephalopathy
• Interventions: Diagnostic Test: Telemedicine consult

• Registration Number: NCT05155111
• Lead Sponsor: MaineHealth

Brief Summary

This is a clinical trial using telemedicine as an intervention twice in the first 6 hours of life to assess neonatal encephalopathy, one of the key factors involved in the decision to treat a neonate with therapeutic hypothermia (TH). The investigators aim to enroll up to 30 neonates, anticipating that there will be about 5 neonates, who do not demonstrate moderate to severe neonatal encephalopathy, and therefore do not meet criteria for treatment with TH. The investigators will prospectively follow the clinical course of all 30neonates through monitoring with electroencephalogram (EEG) for up to 24 hours after birth to determine if seizures are present and by MRI of the brain prior to hospital discharge to determine if there is evidence of brain injury. Neonates will be enrolled in the study for the duration of their hospital admission.

Detailed Description

Neonatal encephalopathy is a clinically defined condition of disturbed neurological function in an infant of greater than 35 weeks gestation. Neonatal encephalopathy is most likely to occur following a traumatic birth that requires some degree of neonatal resuscitation. Therapeutic hypothermia (TH) is the standard-of-care neuroprotective therapy employed for neonates who have symptoms of moderate to severe neonatal encephalopathy. Assessment of neonatal encephalopathy can be challenging because the symptoms can fluctuate and because there is time pressure to decide to initiate TH before the neonate is 6 hours old, after which TH has almost no beneficial effect. Doctors struggle with the decision to treat neonates with milder symptoms and these neonates are at risk for two possible adverse outcomes; 1) an eligible neonate is not recognized and therefore not treated with TH or 2) an ineligible neonate may receive unnecessary treatment. The first error is one that can result in lifelong impairments such as learning delays, epilepsy and cerebral palsy for the untreated child and the second error, of unnecessary treatment is costly, invasive and not without risk of associated issues with morphine exposure, cold-induced injury to the skin or complications from venous access such as infection or blood clot.

In Maine, the investigators have successfully implemented telemedicine both in the tertiary care center and in the rural community hospital to permit visual evaluation of neonates and inform joint decision making in these challenging instances. Telemedicine provides the opportunity to have synchronous, unscheduled immediate expert consultation for neonatologists with pediatric neurology in the tertiary care center and for primary care physicians with both specialists in the community hospital setting. The objective of the present study is to develop the telemedicine consultative network to continue to improve patient selection for TH. The investigators aim to use telemedicine consults in three tertiary care centers (Maine Medical Center, Northern Light Eastern Maine Medical Center and the University of Vermont Medical Center) to develop evidence for the threshold at which neonates can be safely excluded from TH treatment. In Aim 1, the investigators will assess neonates with milder symptoms at least twice in the first 6 hours of life and for those not meeting criteria for moderate or severe neonatal encephalopathy, perform electroencephalogram (EEG) to rule out seizures and MRI of the brain to rule out injury. In aim 2, the investigators will compare the interrater reliability between the neonatologist neonatal encephalopathy exam and the one performed via telemedicine by the pediatric neurologist.

Arm && Interventions

Group	Intervention	Description
Telemedicine arm	Telemedicine consult	Neonates will have telemedicine consultation to evaluate symptoms of neonatal encephalopathy

Primary Outcome Measures

Name	Time	Method
Combined outcome of seizure or brain Injury on imaging	First 10 days of life	The primary outcome is a combined outcome. This will include the presence of absence of seizure activity on the electroencephalogram (EEG) during the first 24 hours of life and/or the presence or absence of injury to the brain detected on magnetic resonance imaging of the brain (MRI) performed prior to hospital discharge.
