Welcome to Beth Israel Deaconess Medical Center's Home Nutrition Support
This service is directed by Nicholas Tawa, MD, PhD, a member of the
Division of Surgical Oncology at BIDMC, in conjunction with Susan McAreavey
RD, LDN, who serves as Clinical Coordinator for the program. Our team works
together with the home care companies servicing individual patients to
ensure safe and nutritionally sound intravenous nutrition support. We are
available for new patient evaluations in both the outpatient and inpatient
setting. Our focus is the patient requiring parenteral (intravenous)
feeding, as opposed to enteral (gut) feeding, although in some instances a
complex approach to management requiring both feeding modalities will be
Total parenteral nutrition (TPN) can provide all of the nutrients the
human body requires to maintain adequate nutrition and to support
growth and healing, and is most often started in the hospital at the
time of acute illness or following surgery.
At BIDMC, inpatient registered dietitians work together with the
healthcare team to make appropriate recommendations for starting and
advancing TPN based on nutritional needs.
Once at home, a home care company, often with the assistance of the
Visiting Nurse Association (VNA), and under the direction of Dr. Tawa,
provides the TPN formula, assists with venous access devices, and
provides additional services as needed.
The TPN formula is adjusted weekly or as needed by our team, based on
laboratory and other clinical data.
In addition to prescribing the TPN solution and metabolic management, our
program also provides additional supervision of enrolled patients, with
periodic outpatient visits to Dr. Tawa and telephone contact as needed. Our
goal is to provide the TPN-dependent individual the most normal,
unhindered, and healthy life possible.
