Visit 1. While in the waiting room, caregivers for all eligible children will respond to an item on the PSF as follows: "Does your child consistently snore 3 or more nights per week?" For caregivers in CHICA-OSA clinics, a "yes" response will trigger additional questions about signs and symptoms of OSA. Specific items corresponding to the symptoms will be taken from the Pediatric Sleep Questionnaire (PSQ19) and include observed apnea, snorts, gasps, daytime sleepiness, and other signs and symptoms listed in the AAP guideline paper. The PCP will then receive a PWS prompt listing signs and symptoms that apply to the child, based on either existing data in the electronic record (e.g., current ADHD diagnosis; overweight) or on caregiver responses to items assessed in the waiting room (e.g., observed apnea; daytime sleepiness). When evidence-based criteria are met, according to the 2012 American Academy of Pediatrics (AAP) guidelines, the PCP will be encouraged to refer the child (for a PSG, to a sleep specialist, or to an ENT).
