Internal Medicine

Internal Medicine


The Section of Internal Medicine at Westchester Medical Center focuses on the diagnosis and treatment of serious or unusual diseases in adults. Know as internists, physicians in internal medicine often consult with other doctors to determine diagnoses and treatment interventions on complex cases where a patient's condition is not immediately obvious.

Hospitalist Division

Hospitalists are physicians who specialize in the treatment of hospitalized patients. At Westchester Medical Center, a group of Hospitalists work as a team with medical residents and students. Our faculty consists of 10 full-time hospitalists, two of whom are nocturnists. They play an extensive role in the supervision of the housestaff on the medicine inpatient service. The hospitalist group is an integral part of the new computerized, handheld sign-out system recently implemented in the Medicine Department which provides a powerful tool for communication of key patient information from one clinician to another. The Division members are very active in clinical research and coordinate many research projects. Areas of research interest include technological solutions to patient care, quality improvement and patient safety, epidemiology, decision analysis, health care research, screening for and early detection of disease, Lyme disease, ethics and innovative methods of clinical teaching.

Adult Cystic Fibrosis Center (CF)

Advances in the medical therapy for cystic fibrosis allow patients to live longer, healthier lives. Generally, CF symptoms appear in the first years of life, but now over 10% of newly diagnosed patients are over 18 years of age. The average life expectancy is now 38 years old, with some patients living into their seventies. The Adult Cystic Fibrosis Center at Westchester Medical Center provides state-of-the-art medications and treatments that improve the longevity and quality of the adult CF patient's life.


Why is a Hospitalist team caring for me?
Our hospitalists, rather than your primary care physician, will care for you while you are in the hospital. This arrangement is beneficial in that you are taken care of by a doctor who focuses exclusively on your care in the hospital. This allows your primary physician to devote his/her time to the office practice, making medical care more effective and efficient.

How will the Hospitalist learn about me?
Hospitalists communicate with primary physicians as needed to ensure optimal care. At the time of admission, records from your doctor will often be requested and your condition discussed to supplement the information we obtain from you. Your primary care physician will be informed about your care at discharge as well, and will receive a copy of your records. If you do not have a primary care physician, we will assist you in obtaining appropriate outpatient follow up and care. Our hospital utilizes a state-of-the-art sign-out system which allows all physicians involved in your care to effectively pass important information about your care to their colleagues during times your primary hospitalist team is not in the hospital.

What are the advantages of hospitalist care?
Hospitalists are able to closely monitor your progress and condition 24 hours a day, seven days a week. Dedicated house staff work in close cooperation with the hospitalists to take care of all your needs during your visit. Because hospitalists work solely in the hospital and are present throughout the day, the physician can see you more than once a day if needed. We know every specialist and department in the hospital and check on your tests periodically to make adjustments in treatment throughout the day.

When do I see my doctor?
You will generally see your doctor after discharge for a follow-up appointment. If you do not have a doctor, we will help you find one and prescribe the necessary medications. Follow up can be arranged on the Westchester campus at our outpatient clinic or at the office of your choice. Discharge instructions and other documents such as a discharge summary will generally be sent to your doctor within 1 to 2 business days.

Will I have the same doctor each day?
We make every effort to have the same Hospitalist see you every day. Because we work as a group, you may see a different Hospitalist or other member of the medicine faculty on the weekends.

Who else will care for me besides my hospitalist?
The attending physician is the hospitalist who is responsible for your care. Attendings are members of the Westchester Medical Center staff and the New York Medical College School of Medicine faculty and have an important role of teaching the other members of the team. Residents and interns are physicians who have completed medical school and are currently training as specialists in internal medicine. Residents are often the first physicians you meet upon being admitted to the hospital and the physi
