Respiratory illnesses are a significant contributor of morbidity and mortality among persons with Down syndrome (DS). Reviews have described respiratory illnesses of DS in childhood, but few have looked across the lifespan. Retrospective chart review of patients in our DS program with clinical encounters for respiratory illnesses from 2011 to 2020 was completed. Eighteen percent of clinical encounters were due to respiratory illnesses. Of these, 120 were seen in the emergency department, 88 were admitted, and 21 were seen in urgent care. Common comorbidities included congenital heart disease, asthma, and dysphagia. Admission was common for children under the age of 5 years and adults over the age of 45 years. Admitted patients were more likely to have history of pneumonia and chronic lung disease. Of admitted patients, 77% required supplemental oxygen and 46% required intensive care unit admission.Our findings highlight that respiratory illnesses are a common cause of healthcare utilization among patients with DS, particularly early in childhood and later in life.
