Case Scenario

• An 85-year-old man with New York Heart Association class IV heart failure, hypertension, and moderate Alzheimer’s disease is admitted to the hospital after a hip fracture.

• His postoperative course is complicated by pneumonia, delirium, and pressure ulcers on his heels and sacrum.

• Respiratory status is worsened with severe shortness of breath and hypoxemia requiring high flow O2 .

• A decision for intubation and mechanical ventilation needs to be made

What would you do next:

A. Intubate the patient and place on MVB. Do not intubate and Inform the family that

prognosis is bad based on his previous conditionC. Meet with the family and ask them what they want

to do and proceed based on their wishes D. Meet the family and help in making decision:

Case Scenario

• 69 year old with PMH of HTN, DM, and COPD• Admitted with pneumonia and required to be

intubated and placed on MV• Condition is worsened with shock, renal

failure requiring dialysis, DIC, severe ARDS and lactic acidosis (LA 8.9)

What would you do next:

A. Continue current level of support, do not dialyze and no escalation of inotrops

B. Discontinue all life support modalities and provide comfort care

C. Escalate therapies, start hemodialysis, and do everything possible.

D. Arrange for family conference and discuss the current condition, prognosis and expectation with the family and make a shared decision

Study of ICU Family Conferences

• Daily screen of all ICUs in 4 hospitals• If conference planned, contact attending:

– Is discussion of withholding or withdrawing life support likely?

– Willing to have conference recorded?

• Consent/survey all participants• 51 family conferences recorded (46%)

McDonagh, Crit Care Med, 2004, 32:1484

Clinician Statements Associated with Increased Family Satisfaction

• Assure family that patient will not be abandoned prior to death

• Assure family that patient will be kept comfortable and not suffer prior to death

• Provide support for family around decisions to withdraw or continue life support

• Answer questions, clarify and follow up on family statements• Acknowledge and address emotions• Explore patient preferences• Affirm non-abandonment

Needs of the Patient

• Receiving adequate pain and symptom management.

• Avoiding inappropriate prolongation of dying• Achieving a sense of control• Relieving burden• Strengthening relationships with loved ones.

Needs of Families

Components of the Withdrawal of Life Support Form

• Preparation– DNAR order; document discussion with family;

discontinue prior orders

• Ventilator withdrawal protocol• Analgesia and sedation

– Infusion with broad range; no maximum dose; document reason for increase

• Principles of withdrawing life support

Should Patients Be Extubated After Withdrawing Mechanical Ventilation?

• Little evidence to guide decisions• Clinicians often have strong opinions • Recent study suggests family ratings of care

higher if patient extubated• Case-based judgment based on

– Family preferences– Level of support, amount of secretions, level of

consciousness

Glavan, Crit Care Med, 2008; 36:1138

Tips for Talking with Family About Withdrawal of Life Support

• When life support is withdrawn, stress– “Care” will not be withdrawn– Aggressive palliation will be used– avoid making firm predictions– about the patient’s clinical course – Time to death variable

• Offer option of family being present– Family presence associated with higher PTSD

• Describe process so they know what to expect

Kross, AJRCCM, 2009; abstract

Summary: Ethical and Practical Issues in End-of-life Care in the ICU

• Decision-making about end-of-life care common in the ICU and should start early

• Shared decision-making at the default– Need to adapt to individual patient and family

• Interdisciplinary communication essential• Incorporate and honor cultural difference• Withdrawal of life support is a clinical

procedure
