Mayo Clinic's approach


At Mayo Clinic, your parenteral nutrition care team may include:

  • Doctors. A surgeon will insert and, if necessary, remove the intravenous catheter used to infuse the parenteral nutrition. A gastroenterologist with special training in nutrition will supervise the medical aspects of your home parenteral nutrition and coordinate treatment with your primary care provider.
  • Nurses. Nurses will include a coordinator, a nurse educator who will train you to take care of your intravenous catheter, and staff nurses who are always available to answer questions and provide support.
  • Pharmacist. A clinical pharmacist will help you understand the use of drugs and nutrients, including the parenteral nutrition. The pharmacist contacts the home care company to arrange for you to receive supplies.
  • Dietitian. A registered dietitian will help you understand your diet and assist in planning appealing meals and snacks. If you need a special dietary product, the dietitian will advise you about its preparation, consumption, cost and availability.
  • Social worker. A social worker will obtain a social and financial history for your home parenteral nutrition team. Home parenteral nutrition is expensive, and many people need financial assistance. The social worker can suggest potential financial and community resources.
  • Home care company. A special company will provide you with supplies, including the parenteral nutrition and clinical services. Your team helps you select a home care company.


Mayo Clinic provides total parenteral nutrition to nearly 1,200 people each year, some of whom receive treatment at home. Your care team is prepared with the experience, knowledge and resources to provide you with exactly the care you need.


Mayo Clinic researchers are studying methods of parenteral nutrition that can reduce the risk of complications and improve the quality of life of people who need intravenous feeding. Specific areas of interest include the effects of parenteral nutrition on liver disease and bone mineral density, and the ethics of long-term intravenous feeding. Researchers at Mayo Clinic are also studying both nutrients and drugs to help decrease the need for long-term parenteral nutrition.
