What if Hospitalization is Required?

In general, the doctors admit their patients to Lourdes Hospital. If for some reason you prefer to be admitted elsewhere, discuss this with your doctor. Our physicians have admitting privileges to all hospitals in the area. If hospitalization is necessary, the decision will be mutually made between the physician and the patient as to which facility to use. Be sure to contact your insurance plan, especially if you belong to an HMO.

Your appointment is important. Please call the office 24 hours in advance if you are unable to keep an appointment. Providers have a daily preset schedule. Arriving late for your appointment will delay other appointments and you may be asked to reschedule.
