  1. Predicting Prognosis: Guidelines for End-of-Life Decisions

  2. Objectives • Identify two general clinical indicators of a life-limiting prognosis • Define two disease-specific prognostic indicators • Verbalize trajectory of decline within diseases which demonstrate hospice appropriateness • Discuss case vignettes for ongoing assessment of prognosis and documentation specific to decline in function within diseases

  3. Medicare Hospice Benefit • Terminal Illness: “A medical prognosis (of a) life expectancy of six months or less if the illness runs its normal course.” • Certified by two physicians: attending and hospice medical director • Recertification requirement includes documented assessment of prognosis of six months or less and demonstrates declining condition

  4. CLINICAL JUDGMENTS • Specific criteria represent pieces of information that should be evaluated in the context of a patient’s clinical condition and clinical course at the time of assessment • This information should be combined with other clinical and psychosocial information • Clinical judgment is based on the needs of the specific patient

  5. General Guidelines “Observations by physicians and others in hospice and palliative care observed that patients who are terminally ill, regardless of the primary diagnosis, had convergence of symptoms and treatment approaches as the time of death became closer.” Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill, 2001.

  6. Determining Prognosis Clinical Progression of Disease • Multiple hospitalizations, ED visits or increased use of other healthcare services • Serial physician assessments, laboratory or diagnostic studies consistent with disease progression • Changes in MDS in LTC facilities • Co-morbidities • Progressive deterioration Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill,2001.

  7. Determining Prognosis Changes in Functional Status • Cancer Patients • PPS < 50 or ECOG > 3 • PPS < 60 or ECOG > 2 with symptoms • Decline in PPS of at least 20 units in 2-3 months • Non-Cancer Patients • Dependence in at least 3/6 Activities of Daily Living • PPS < 50 Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed.

  12. Determining Prognosis Unintentional Weight Loss • > 10% of normal body weight • Body Mass Index (BMI) < 22 kg/m2 Of Note: For ongoing determination of wasting, documentation of Mid-arm Muscle (MMA) is a significant indicator of decline Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill, 2001.

  13. Determining Prognosis Intangible Factors • Patient’s personal goals and approach to his or her disease • Burden of investigation and treatment vs. potential gains for the patient Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill, 2001.

  14. Determining Prognosis Cancer Diagnoses • Stage IV — presence of metastases • Natural history of disease • Sensitivity of the disease to anti-neoplastic therapy • Prior treatment history where indicated Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill, 2001.

  15. Determining Prognosis End-stage Cardiac Disease • Symptomatic at rest or with minimal exertion • Heart Failure: Ejection Fraction < 20% • Dyspnea or chest pain at rest or minimal exertion (NYHA class IV) • Optimal medical therapy or inability to tolerate optimal therapy • Not a surgical candidate Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed. Chapter 1 in: Kinzbrunner BM, Weinreb NJ, Policzer J: 20 Common Problems in End-of-Life Care. New York, McGraw Hill, 2001.

  16. The Stages of Heart Failure – NYHA Classification In order to determine the best course of therapy, physicians often assess the stage of heart failure according to the New York Heart Association (NYHA) functional classification system. This system relates symptoms to everyday activities and the patient's quality of life.

  17. Class/Patient Symptoms • Class I (Mild)No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, or dyspnea • Class II (Mild)Slight limitation of physical activity. Comfortable at rest, but ordinary physical activity results in fatigue, palpitation, or dyspnea. • Class III (Moderate)Marked limitation of physical activity. Comfortable at rest, but less than ordinary activity causes fatigue, palpitation, or dyspnea. • Class IV (Severe)Unable to carry out any physical activity without discomfort. Symptoms of cardiac insufficiency at rest. If any physical activity is undertaken, discomfort is increased.

  18. End-stage Cardiac Disease “There is a failure to recognize that end-stage heart failure patients frequently come in and out of the hospital over and over again and suffer a lot with really no impact on their ultimate survival” Mariell Jessup, MD, FACC, medical director of the heart failure and cardiac transplantation program and professor of medicine, Univ of PA 9/05/05

  19. End-stage Cardiac Disease • ACC/AHA Practice Guidelines (2005) recommendations • Stage D Refractory Heart failure (HF) requiring specialized interventions • Recurrently hospitalized or • Cannot be safely discharged from the hospital without specialized interventions • Marked refractory symptoms at rest • Shortness of breath • Fatigue • Reduced exercise tolerance • Compassionate end of life care/hospice • Extraordinary measures

  20. End-stage Cardiac Disease • Co-morbid conditions associated with poor prognosis • Symptomatic arrhythmias resistant to antiarrhythmic therapy • History of cardiac arrest and resuscitation • History of syncope, regardless of etiology • Cardiogenic brain embolism • Concomitant HIV disease Kinzbrunner BM: Predicting Prognosis: How to Decide when End-of-Life Care is Needed.

  21. End-stage Pulmonary Disease • In advanced disease the clinical course of patients usually consists of periods of relatively stable disease punctuated by episodic acute decompensation • In disease progression: • Acute episodes become more frequent • Periods of stability become the exception rather than the rule
