Subsequent Visits: At the next visit (sick or WCC), snoring will again be assessed as one of the health surveillance questions for all eligible children. However, children from the CHICA-OSA clinics who were referred for PSG at the previous visit will receive an additional item asking whether or not the child has had an adenotonsillectomy in the past year. If the child has not had this surgery the PCP will receive a prompt to assess the outcome of the original referral (e.g., PSG did not suggest OSA; PSG suggested OSA and surgery scheduled; PSG scheduled; adenotonsillectomy scheduled; family does not have appointment) and re-refer if appropriate. If a caregiver reports that a child has had a T&A and no longer snores, the PCP will not receive any additional prompts and snoring will be reassessed in two years. However, if a caregiver reports residual snoring after surgery, the provider will receive a prompt to refer for possible residual OSA.
