EPEC - Oncology Education in Palliative and End-of-life Care - Oncology Module 11: Withdrawing Nutrition, Hydration
Overall message Withholding or withdrawing a therapy, such as artificial nutrition or hydration, is ethical and legal in some circumstances.
Objectives • Withholding or withdrawing therapy • Evidence base for artificial nutrition and hydration • Approach to discussing artificial nutrition and hydration • Features of artificial nutrition and hydration that favor use in spite of the evidence
Role of the oncologist . . . • Help the patient and family: • Elucidate their values • Understand the facts • Dispel misconceptions • Establish goals of care • Facilitate decisions, reassess regularly
. . . Role of the oncologist • Discuss alternatives • Including palliative and hospice care • Document preferences, medical orders • Involve, inform other team members • Assure comfort, lack of abandonment
Resuscitation Elective intubation Surgery Dialysis Blood transfusions, blood products Diagnostic tests Artificial nutrition, hydration Antibiotics Other treatments Future hospital, ICU admissions Life-sustaining treatments
Enteral nutrition • NG, PEG, J tubes • Use gastrointestinal tract • Temporary inability to eat • Neurological injury • UGI mechanical obstruction Shike M. HematolOncolClin North Am. 1996.
Effect of enteral nutrition on survival • Higher mortality • 50% dead at 12 months • 60% dead at 18 months • No reduction in aspiration • No reduction in risk of pneumonia • No evidence of better symptom control Finucane TE, Christmas C, Travis K. JAMA. 1999 .
Parenteral nutrition • Intravenous (central line) • No benefit in routine perioperative, ICU settings • Benefit in prolonged GI tract toxicity • Benefit in absence of GI tract function in otherwise healthy patient (short gut) Mercandante S. Support Care Cancer. 1998.
Effect of parenteral nutrition on survival and response rates ACP Consensus Statement. Ann Int Med. 1989.
Evidence conclusion • When cancer is the cause of the anorexia and weight loss, prospective randomized studies have failed to show benefit of artificial nutrition. ACP Consensus Statement. Ann Int Med. 1989.
Parenteral hydration • Intravenous • Subcutaneous (hypodermoclysis) • Equally efficacious, less risk, less skill, less cost • Doesn’t relieve dry mouth McCann RM, Hall WJ, Groth-Juncker A. JAMA. 1994 .
Common concerns • Legally required to “do everything”? • Is withdrawal, withholding euthanasia? • Are you killing the patient when you withhold or withdraw artificial nutrition and hydration?
Seven steps to discuss nutrition & hydration . . . • Be familiar with policies, statutes. • Appropriate setting for the discussion • Ask the patient, family what they understand. • Discuss general goals of care.
. . . Seven steps to discuss nutrition & hydration • Establish context for discussion. • Discuss specific treatment preferences: will nutrition & hydration achieve goals? • Respond to emotions. • Establish and implement the plan. • Reassess and revise periodically.
Address misperceptions • Cause of poor appetite, fatigue • Relief of dry mouth • Urine output
Emotions • Not “fighting” • Not “doing something” • “Starving to death” • “Dehydrating to death” • “Let nature take its course” McClement, et al. J Palliat Med. 2003.
Help family and staff • Identify feelings, emotions, need “to do something” • Identify other ways to demonstrate caring • Teach the skills they need
Normal dying • Loss of appetite • Decreased oral fluid intake • Artificial food/fluids may make situation worse • Breathlessness • Edema • Ascites • Nausea/vomiting Ganzini L, et al. N Engl J Med. 2003.
Discussing hospice care • Hospice care: Present as a response to need vs. something to do when nothing left to do • Elicit patient and family understanding of situation • 10 to 15% of patients referred to hospice care dis-enroll (graduate)
Summary Withholding or withdrawing a therapy, such as artificial nutrition or hydration, is ethical and legal in some circumstances.
