through the patient's EHR, and they received an automatic in-basket message through the EHR as well as a notification by the research coordinator or research assistant when results were back.

Data Collection and Outcomes {#s3}
----------------------------

Follow-up treatment and outcome data were abstracted from each subject's EHR by a trained research staff member. Abstracted data included medical history, clinical signs and symptoms, demographics, lab and radiology results, medications (including asthma, diabetes, chemotherapy, immunosuppressive, antibiotic, and antiviral medications), ED/hospital course, length of ED/hospital stay, clinician diagnoses from the index encounter, and limited review of subsequent encounters to identify deaths and 30-day revisits to the ED study site for similar complaints. Up to 3 return visits were recorded, and each was categorized as either "respiratory illness" or "nonrespiratory illness" according to the primarywhen one of the plurality of posts is engaged into the slightly smaller sub-slot, said narrow strip firmly engages said post into the sub-slot, thereby reducing a noise level associated with loose fitting coupling components. This embodiment includes an end cap disposed at the end of the hollow core nest that covers the slots, preventing the posts of the elongate bodies from disengaging from the slots. Preferably, elastomeric shims are disposed in the sub-slots not engaged by the plurality of posts.
When properly assembled, the plurality of posts of the elongate body connected to the drive shaft drivingly engage the solid side of the sub-slots, and the plurality of posts of the elongate body connected to the driven member are driven by the solid sides of the sub-slots, when
