Meriter Hospitalist Program


 
To ensure the best possible care for patients who must be hospitalized, Meriter Hospitalists provide medical services 24 hours a day, seven days a week.

Our team of highly qualified, dedicated hospitalists - physicians who specialize in the care of hospital patients - works closely with your primary care physician and specialists. To learn about the members of our team, please read the physician profiles below.
 

How the Hospitalist Program Works

At the time of your admission, your physician contacts the hospitalist on duty to provide pertinent information about your illness, your health history and any special needs or concerns. The process is similar to what he or she does when referring you to any specialist.

The hospitalist's role is to assist you through a smooth, quick recovery process by managing and coordinating all aspects of your care at Meriter. Having one or more hospitalists onsite at all times means we're never more than a few minutes away. In case of emergencies or changes in your condition, you can be assured a physician will be close by to respond quickly.

During your stay, we will remain in contact with your physician, providing regular updates. Upon discharge, information will be forwarded to your physician's office to add to your medical record.
