Hospitalist Services
Hospitalist Services consists of providers who are specially trained in inpatient care and are considered inpatient specialists. The Hospitalist Services providers are specially trained in internal medicine. Your primary care physician has made them available to you in the event that you require hospitalization.
Our hospitalists will keep your primary care physician informed of your progress while you are in the hospital. The hospitalist is also available to you while you are in the hospital and will see you soon after you are admitted.
Why use our Hospitalist Progam?
Our hospitalists are:
- Familiar with key staff in the hospital, including medical and surgical consultants, discharge planners, clergy and other employees, which improves care
- Able to rapidly respond to problems or crises that may arise during patient care
- Partners with primary care physicians in coordinating specialized medical treatment for individual patients
- An excellent resource for patients without a primary care physician
How do I use the Hospitalist Program?
If your physician or specialist believes that you need to be hospitalized, he or she may choose to coordinate your admission with our Hospitalist group. The hospitalist(s) will be in frequent contact with your physician, relaying the details of your care. If you are admitted through the Emergency Department, your physician will be promptly notified of your status and condition.
Once you've been admitted under the care of the hospitalist group, a hospitalist will be in charge of your care and will see you daily. Throughout your stay, they will work together with your physician to ensure that you obtain the best care possible.
The Hospitalist group will:
- Assess and treat your medical condition
- Coordinate your hospital care
- Establish a relationship with you and your family
- Review your progress with your physician
- When discharged, transition medical care back to your primary physician, who will resume the responsibility for ongoing outpatient treatment
- Assist patients in finding a primary care physician for those who do not already have one
What if I need a specialist while I am in the hospital?
Sometimes consultation with other specialists is necessary to ensure that you receive the best care we have to offer. The Hospitalist Services provider will coordinate your care with other specialists as needed.
