Internal Medicine › NuHealth - Nassau Health Care Corporation

Internal Medicine

Focused on the diagnosis and non-surgical treatment of diseases affecting adults, Internal Medicine is one of the hospital’s busiest departments. Our subspecialists are frequently called upon by physicians both inside and out of Nassau University Medical Center to help solve the most complex diagnostic puzzles, including those where multiple illnesses or multiple organs are involved. In addition to helping patients manage a broad range of acute and chronic illnesses on an outpatient basis, NUMC’s internal medicine subspecialists are on the frontline of inpatient care. Some of the recent advances in the Department of Internal Medicine include:

  • Hospitalist Medicine Service – Hospitalists are solely responsible for managing the care of NUMC inpatients, coordinating the activities of multiple specialists to improve patient outcomes.
  • Gastrointestinal Services – Multiple clinics weekly and expanding endoscopy services
  • Critical Care Medicine – All intensive care patients are now managed by board certified critical care physicians who are expert at helping those recovering from surgery or trauma or struggling against life-threatening illness.
  • Sleep Medicine – A growing national problem, sleep apnea and other pulmonary (breathing) problems put tremendous strain on the heart and can result in death. We can eliminate the terror of suddenly starting awake while struggling to take a breath.

When your kidneys are unable to perform due to renal disease, toxic substances (impurities and wastes) and excess fluid from the blood can build up, eventually leading to death if not removed. Our unit offers two forms of Dialysis which are Hemodialysis and Peritoneal Dialysis. Hemodialysis is a method of diverting blood from the patient to a dialysis machine where it is filtered before being returned to the body. Most patients require three treatment sessions each week, each of which lasts 3-4 hours.

Peritoneal Dialysis is a form of dialysis that is performed at home after being thoroughly trained by our staff. Patients attend a monthly clinic at the outpatient center.

At the NuHealth Dialysis Center at A. Holly Patterson Extended Care Facility, a caring, highly-experienced professional staff provides personalized, state-of-the-art outpatient renal dialysis services in a bright, comfortable new setting. Our goal is to deliver the best treatment in a manner that is reassuring and respectful of each patient's dignity.


  • Individualized care plans
  • Outpatient hemodialysis
  • Outpatient peritoneal dialysis
  • Patient and family education
  • Nutrition consultation
  • Home peritoneal dialysis training program
  • 24/7 nursing support.
  • Psychosocial support programs

Sophisticated Stations
The NuHealth Dialysis Center features 29 new Fresenius hemodialysis stations that incorporate the best of today's technology, including a highly sophisticated reverse osmosis system for water purification.

Conveniently located in the heart of Nassau County, it features plenty of parking and spacious, windowed rooms. Each station has its own flat screen video monitor and access to a substantial library of feature films, educational videos and other entertainment options to keep patients occupied during treatment. In addition to a comfortable waiting area, there is also a patient lounge with vending machines that offer real, healthy food choices, not just snacks.

Hospital Medicine

In years past, inpatients at most hospitals might be seen by multiple medical and surgical specialists – each concerned with their own aspect of the patient’s health, but none specifically responsible for the patient’s care as a whole. NuHealth has changed all that with the introduction of hospital medicine and the hospitalist: a physician whose sole concern is the well-being and safety of patients staying at Nassau University Medical Center.

The hospitalist is both physician and case manager, coordinating the activities of a multidisciplinary team to avoid test duplication, medication errors and care plans that work at cross purposes. NuHealth’s specialists in hospital medicine also act as the patient and family’s advocate, helping voice their concerns to the team to provide the best possible patient experience. They also are the liaison to the patient’s referring physician, and help ensure a smooth transition into and out of the hospital.

Our immune system can be both our greatest friend and our worst enemy. It protects us from bacteria and other antigens, producing antibodies to fight off infection. At the same time, it can overreact, producing antibodies in reaction to harmless substances: allergies that can range from the merely annoying to the downright dangerous.

In addition to helping patients with immuno-deficiencies, NuHealth’s immunology department provides testing and patient care to help combat all types of allergies, including:

  • Allergic Rhinitis (hay fever)
  • Asthma
  • Contact Dermatitis
  • Drug Allergies
  • Food Allergies
  • Immune Disorders
  • Insect Allergies
  • Mast Cell Disorders
  • Sinusitis
  • Skin Allergies

Our kidneys are responsible for filtering out waste products from our blood, which is then passed out of the body as urine. As a result, many diseases affecting the kidneys aren't limited to the actual organ, and may originate from sources outside the renal system. The Nephrology division at Nassau University Medical Center is focused on the diagnosis and treatment of the full array of renal and hypertensive disorders. Using a variety of diagnostic tools, including ultrasound-guided renal biopsies, urinalysis and immunological studies, NuHealth's nephrologists treatment conditions such as:

  • Acute Renal Failure
  • Chronic Kidney Disease
  • Hematuria (blood in the urine)
  • Proteinuria (excess protein in the urine)
  • Kidney Stones
  • Chronic Urinary Tract Infections
  • Hypertension
  • Electrolyte Disorders or acid/base imbalance
  • Autoimmune Diseases
  • Polycystic Kidney Disease

In addition, NuHealth’s Nephrology division manages dialysis units at both Nassau University Medical Center and A. Holly Patterson Extended Care Facility.

Palliative Care

Palliative care is specialized medical care for people with serious illnesses. Care is focused on providing patients with relief from the symptoms, pain, and stress of a serious illness-whatever the diagnosis. The goal is to improve the quality of life for both the patient and the family.

Palliative care is provided by a team of doctors, nurses, and other specialists who work with a patient's other doctors to provide an extra layer of support.

Palliative care is appropriate at any age and at any stage of a serious illness and can be provided together with curative treatment.

Working closely with your primary doctor, Palliative Care provides:

  • Expert treatment to relieve your pain and symptoms.
  • Close communication about your illness and treatment choices.
  • Coordination of your care among all of your health care providers.
  • Emotional and spiritual support for you and your family.
  • Referral and coordination of home care services.
  • Help in navigating the health care system.
  • Assistance with difficult treatment choices.
  • Detailed practical information and assistance.

What you should know about Palliative Care:

  • You can continue to receive care to cure your illness and Palliative Care at the same time.
  • Palliative Care focuses on managing symptoms that are causing discomfort, while you continue with your medical treatments.
  • Palliative care helps at all stages of illness. It is best introduced early in your care and can be helpful whether your illness is curable, chronic, or life-threatening.

Is Palliative Care the same as Hospice Care?

No. Hospice Care is meant specifically for those approaching the last stages of a serious illness.

What can I expect from Palliative Care?

  • Relief from symptoms such as pain, shortness of breath, fatigue, constipation, nausea, difficulty sleeping and loss of appetite.
  • Improved ability to carry on with your daily life.
  • Improved ability to tolerate medical treatments.
  • Better understanding of your condition and your choices for medical care.
