EPEC - Oncology Education in Palliative and End-of-life Care - Oncology Module 8: Clarifying Diagnosis and Prognosis
Objectives • Describe the difficulty with prognostication • Discuss limitations of current prognostic models • Apply the six-step protocol to communicate diagnosis and prognosis
Importance • Most people want to know • Strengthens physician-patient relationship • Fosters collaboration • Permits patients, families to plan, cope
Inaccuracy of prognostication Studies of Clinical Predictions of Survival vs Actual Survival
Clinical predictions vs. actual survival • Overoptimistic by factor of 3 - 5 • Glare P.BMJ.2003 .
Clinical predictions vs. actual survival • Relationships between predictions and survival: • Actual is 30% less than predicted • Actual survival equaled predicted plus or minus 1 week for 25% • Predicted survival was 4 or more weeks longer than actual survival for 27% Glare P. BMJ.2003.
Sources of prognostic information • Physician prediction • Stage-specific survival data • Performance status • Signs and symptoms • Integrated models
Sources ofsurvival data . . . • Stage-specific survival curves • Natural history studies • Randomized trials with a “best supportive care” arm
Performance status and prognosis . . . • Independent prognostic factor • Karnofsky Performance Score less than 50: survival less than 8 weeks Mor V, et al. Cancer. 1984.
. . . Karnofsky Score as predictor of survival Reuben DB, Mor V, Hiris J. Arch Intern Med. 1988.
Clinical signs and symptoms as prognostic indicators in patients with advanced disease
Six-step protocol . . . • Getting started • Finding out what the patient knows • Finding out how much the patient wants to know Adapted from Robert Buckman
Communicating prognosis . . . • Some patients want to plan • Others seek reassurance
. . . Communicating prognosis . . . • Limits of prediction Hope for the best, plan for the worst Better sense over time Can’t predict surprises, get affairs in order • Reassure availability, whatever happens
. . . Communicating prognosis . . . • Inquire about reasons for asking • “What are you expecting to happen?” • “How specific do you want me to be?” • “What experiences have you had with: others with same illness?” others who have died?”
. . . Six-step protocol • Sharing the information • Responding to feelings of patient, family • Planning, follow-up Adapted form Robert Buckman
. . . Communicating prognosis • Patients vary • “Planners” want more details • Those seeking reassurance want less • Avoid precise answers • Hours to days. . .months to years • Average
Summary • Prognostication is inexact. • Karnofsky performance status is an important prognostic factor. • In advanced disease, symptoms predict prognosis. • Prognosis is difficult to define for patients with survival greater than 6 months.
