Hospitalist is consulted for admission.   Hospital Course   Due to an episode of hypoxia as well as underlying immunocompromise state he was a started on IV Remdesivir and IV dexamethasone.  He was continued on IV fluids for his AKI and renal function started to improve.  He did not require further supplemental oxygen and CT of the chest was showing scant pneumonia only.  His renal function improved, clinically he was better and his mentation improved.  He was given higher dose of dexamethasone as he was being on chronic prednisone/immunosuppression. Patient is completing 5 dose of IV Remdesivir today.  He did well with the physical therapy and wished to go home without home health services/home PT.  Discussed with patient daughter regarding discharge planning. I advised him to take additional 5 days of oral dexamethasone and can switch to his regular dose of prednisone.
