For immediate concerns, our Same Day Care is available from 7:00 am to 7:00 pm, seven days a week. This service is designed for non-life-threatening conditions and is provided on a walk-in or call-in basis. Please note that OHC does not have an emergency room. When our center is closed, a Nurse Call Line is available from 7:00 pm to 7:00 am every day. By calling our main line (605-355-2500) after hours, Relatives will be connected with a Registered Nurse who can offer advice on health questions or concerns or direct them to an emergency room if necessary.
