Patient data will be collected prior to being de-identified. We will use the patient name and medical record number to access their chart in the EMR. Then the following data will be obtained from the chart: 1) chief complaint, 2) temporal artery temperature, 3) cutaneous temperature, 4) ambient temperature, 5) respiratory rate, 6) oxygen saturation, 7) chest x-ray results and relevant data, 8) discharge diagnosis, and 9) disposition. The x-rays will be obtained, uploaded to the LifeImage application, de-identified, and then sent to the radiologist on our research team with the appropriate study ID. The patient information will then be de-identified and replaced with a study ID.
