Once criteria are met, patient charts will be pulled or reviewed electronically. We will then compose a database that includes no patient identifiers but contains information regarding the cause, length, and outcome of the ARDS admission and PICU stay. Factors such as nutritional status, antibiotic and muscle relaxant use, and type of ventilation used will be examined. Other care-related variables will be included if they are felt to impact outcome during the review process. The database will then be analyzed and information regarding pediatric ARDS outcomes in our institution will be published.
