CoolCap Followup Study-Coordination of Participating Centers

Study Overview
=================
Brief Summary
-----------------
This observational study will assess long-term functional outcome of survivors from neonatal encephalopathy who were previously treated with either head cooling or with conventional care in a randomized clinical trial. Children's parents will be interviewed by phone by trained staff using the WeeFIM questionnaire to ascertain the childrens' functional performance on a set of skills basic to daily life. This instrument is able to assess a very wide range of abilities, from independently functioning to needing total assistance. The ratings will be used to examine the relationship between the outcome previously measured at 18 months age and functional outcome at school age and to triage the children into those who clearly could not be tested on standardized exams of cognitive functioning, those who potentially could, even if at a low level of cognitive ability, and those who appear to be functioning at an age-appropriate level.

Detailed Description
-----------------
Previous studies have demonstrated that hypothermia for hypoxic-ischemic encephalopathy in the neonatal period is generally safe and feasible, and can improve intermediate term survival without handicap. There is, however, no information on whether cooling improves longer term (school-age) outcomes in non-handicapped survivors. The current observational trial is designed to help obtain additional followup information on children who participated in the initial randomized clinical trial of head-cooling for neonatal encephalopathy. A first step is to collect information on the current status (at 7-8 years of age) of participants in the original study using a standardized telephone questionnaire. This will allow the investigators to more appropriately target children for whom further, more detailed, in-person neurodevelopmental testing would be appropriate. Given limited resources, identification of children for whom such testing would be helpful and instructive is a necessary goal.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| 1<br>Randomized to cooling (original randomized clinical trial): All children, now 6-8 years old who were randomized to cooling in the original trial were included in this arm. Cooling was achieved via the CoolCap system (Olympic Medical/Natus Corporation) in these babies. | |
| 2<br>Randomized to standard care (original randomized clinical trial): All children, now 6-8 years old, who were treated using the standard of care at the time (normal temperature) were included in this arm. Infants' temperatures were monitored per standard of care. Most infants were cared for on an open wamer that was servo-controlled to normal body temperature (37 C) or in a standard bassinette. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| WeeFIM Score | WeeFIM instrument (the Functional Independence Measure for Children, Uniform Data System for Medical Rehabilitation, Buffalo, NY) is a set of ratings of 18 skills divided into 3 general domains: 8 Self-care; 5 Mobility; 5 Cognition. Caregivers rate a child about extent of independence, full functioning, in carrying out each of those 18 skills, on a scale from 1 for total assistance, total dependence, maximal prompting, or not testable to 7 for complete independence. The ratings are combined to yield 3 Domain scores and a WeeFIM Total. Favorable=mean+/-2SD. We are reporting the percentage of participants with a favorable response. | 7-8 years after initial intervention |
