Long Term Follow up of Children Enrolled in the REDvent Study

This is a prospective observational follow-up study of children enrolled in a single center randomized controlled trial (REDvent). Nearly 50% of adult Acute Respiratory Distress Syndrome (ARDS) survivors are left with significant abnormalities in pulmonary, physical, neurocognitive function and Health Related Quality of Life (HRQL) which may persist for years.Data in pediatric ARDS (PARDS) survivors is limited. More importantly, there are no data identifying potentially modifiable factors during ICU care which are associated with long term impairments, which may include medication choices, or complications from mechanical ventilator (MV) management in the ICU including ventilator induced lung injury (VILI) or ventilator induced diaphragm dysfunction (VIDD). The Real-time effort driven ventilator (REDvent) trial is testing a ventialtor management algorithm which may prevent VIDD and VILI. VIDD and VILI have strong biologic plausibility to affect the post-ICU health of children with likely sustained effects on lung repair and muscle strength. Moreover, common medication choices (i.e. neuromuscular blockade, corticosteroids) or other complications in the ICU (i.e. delirium) are likely to have independent effects on the long term health of these children. This proposed study will obtain serial follow-up of subjects enrolled in REDvent (intervention and control patients). The central hypothesis is that preventing VIDD, VILI and shortening time on MV will have a measureable impact on longer term function by mitigating abnormalities in pulmonary function (PFTs), neurocognitive function and emotional health, functional status and HRQL after hospital discharge for children with PARDS. For all domains, the investigators will determine the frequency, severity and trajectory of recovery of abnormalities amongst PARDS survivors after ICU discharge, identify risk factors for their development, and determine if they are prevented by REDvent. They will leverage the detailed and study specific respiratory physiology data being obtained in REDvent, and use a variety of multi-variable models for comprehensive analysis. Completion of this study will enable the investigators to identify ICU related therapies associated with poor long term outcome, and determine whether they can be mitigated by REDvent.
