Surgical Hx: cholecystectomy  SH: former smoker, lives with daughter  FH: noncontributory  12/6/21: Patient is a 91 year old female with PMH osteoporosis and vascular dementia who initially presented to the ED for confusion for 4 days in the setting of cold symptoms and other sick contacts within the home.  She was saturating well on room air and was afebrile, however did test positive for COVID.  She also noted dark and cloudy urine similar to previous UTI's. Urine was notable for a UTI for which she was treated with a 3 day course of IV ceftriaxone.   Confusion was thought to be due to hyponatremia which was slowly corrected with free water restriction and NS boluses.  CT head indicated no acute findings.   Throughout her admission her sodium normalized and she remained asymptomatic with COVID.  She did not qualify for any treatments for COVID per protocol aside from anticoagulation for which she was treated with subcutaneous heparin.  She never required supplemental oxygen.  Her family was initially requesting SNF placement due to deconditioning however upon finding out that the patient would need to remain in the hospital until 10 days from the first positive test due to regulations at the nursing home they chose to have her discharge home to their care instead with COVID safe at home and VNA.  On day of discharge patient was unhappy, believing she would have to stay, however was not requiring any supplemental oxygen and remained asymptomatic.   IMPROVE VTE score at discharge was 1 so patient did not require any outpatient anticoagulation.
