November 20, 2020 updated by: Renée Shellhaas, MD, University of Michigan
The purpose of this study is to examine whether the duration of treatment with phenobarbital has an impact on neurodevelopmental and epilepsy outcomes, as well as parent and family well-being, after neonatal seizures.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 second to 2 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Newborns with seizures who were admitted at one of the participating children's hospitals

Description

Inclusion Criteria:

  • Neonates <44 weeks corrected age at seizure onset
  • Seizures due to acute brain injury
  • Parent(s) who are English or Spanish literate (with assistance of interpreter)

Exclusion Criteria:

  • Neonates at risk for adverse outcome independent of seizures and underlying brain injury
  • Neonates with mild, temporary causes for seizures
  • Newborns with neonatal-onset epilepsy syndromes

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Outpatient Enrollees
This is a cohort of 150 subjects who were previously enrolled in the Neonatal Seizure Registry, a multi-center association of institutions across the United States, They were contacted to participate in the study after discharge from the Neonatal Intensive Care Unit (NICU) but prior to the prospective follow up. They were asked to take part in all prospective follow up surveys at 12, 18, & 24 months of age.
Other: Surveys
Regarding development, epilepsy, and family impact
Other Names:
  • Former Neonatal Seizure Registry Subjects
NICU Enrollees
This is a cohort of 150 subjects who were enrolled in the study prior to discharge from the NICU. They were asked to complete surveys prior to discharge from the NICU, returned to the hospital for a 1 hour EEG to monitor brain activity between 2-4 months of age, & completed the follow surveys at 12, 18, & 24 months of age.
Other: EEG

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
WIDEA Neurodevelopmental Outcome Score
Time Frame: 24 months
The Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA FS) allowed us to compare the functional development between newborns who received short duration phenobarbital treatment and prolonged phenobarbital treatment. There were 50 questions with response options of 1(Never) to 4(all the time). WIDEA range was on a scale from 50-200 (At 24 months, the normal population mean score is 172±10).The higher the score the better the child's developmental function. Mean scores were calculated using data from any participant who completed surveys at 24 months.
24 months
Number of Participants With Post-neonatal Epilepsy
Time Frame: 24 months
The diagnosis of epilepsy and the details of seizure types and frequencies were determined by telephone interview with the parent and corroborated by medical record review.
24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Length of Stay for the Neonatal Seizure Admission
Time Frame: length of stay, measured in days, will be recorded during a chart review when the child is 12 months of age
Evaluation of medication exposure (dose and duration) during the admission as a predictor of the number of days the infant requires care (length of stay)
length of stay, measured in days, will be recorded during a chart review when the child is 12 months of age
Impact of Treatment Duration on Parent and Family Well-being
Time Frame: 24 months
Surveys selected with the help of our Parent Partners were given at 12, 18, and 24 months to assess the impact of neonatal seizure treatment duration on parent and family quality of life and well-being. The 24 month data is presented, as they align with the primary outcome. The study team reviewed the HADS 24 month Anxiety and Depression Score range of possible scores from 0-21 (higher = more depressed/more anxious), the 24 month Transformed WHO Overall Quality of Life and General Health score range of scores 0-100 (higher=better quality of life), the 24 month Impact on Family Scale overall impact scale range from 15-60 (higher = more impact on family), the 24 month Post Traumatic Growth Inventory scale range from 0 -105 (higher = better/more growth), and the 24 month Impact of Events Scale-Revised scale range from 0 - 88 (higher score = worse impact).
