Our autonomic chart review (ACR) procedure was adapted based on the item structure and subsections within the Pediatric Autonomic Symptoms Scale (PASS; (Ming et al., 2011)). Items within the each of the four sections (I. Mood, Behavior, and Emotion; II. Secretomotor;/Sensory Integration; III. Urinary/ Gastrointestinal Systems; and IV. Circulation, Thermoregulation, Sleep Patterns, and Breathing) were used to established search terms and relevant smart phrases for manual chart review related to autonomic symptoms. Symptoms captured were summed, resulting in a ACR Total score as well as subsection scores that paralleled those PASS sections outlined above.
