3 Overview What is periviable? What is viability? Why does it matter? What are the outcomes? Decision making under uncertainty How do we counsel in this setting? Roe V. Wade For the stage subsequent to viability the State, in promoting its interest in the potentiality of human life, may, if it chooses, regulate, and even proscribe, abortion except where necessary, in appropriate medical judgment, for the preservation of the life or health of the mother. No Colorado Translation: After viability, states may restrict or ban abortions except necessary to preserve the life or health of the woman. No Oregon From Guttmacher institute

6 Impact of Long-term Outcomes Overview Down Syndrome CP Severe MR/CP What is periviable? What is viability? What are the outcomes? What are the potential interventions? Decision making under uncertainty How do we counsel in this setting? MR/CP Decision Making Under Certainty Many of our day to day decisions What to eat? What to wear? Entertainment (what to watch)? Many decisions with less certainty What to eat in a foreign city? (e.g. Shanghai) What to wear on a trip? 6

7 Examples of uncertainty What to eat in a foreign city? Will you need to eat? Very certain How enjoyable will the food be? Variable How dangerous will the food be? Variable What to wear on a trip? Will you need underwear? Very certain Will you need a raincoat? Variable How comfortable will you be (warm/cold)? Variable How dangerous will the clothing be (exposed skin)? V Examples of uncertainty in medicine Effect of therapy Cesarean for delivery of baby very certain Abx in labor for T of degrees uncertain need Cerclage for a short cervix uncertain benefit MgSO4 for CP prophylaxis uncertain benefit/need Chemotherapy for Ovarian CA uncertain benefit / harm One approach Rational, expected value Think of this as lottery Two potential outcomes: 50% chance Win - $10, 50% chance Lose Price of lottery A fair price - $5 who will pay $5? 60% chance Win - $10, 40% chance Lose Price of lottery A fair price - $6 who will pay $5? One approach Rational, expected value Think of this as lottery Two potential outcomes: 50% chance Win - $10, 50% chance Lose Price of lottery A fair price - $5 who will pay $5? 60% chance Win - $10, 40% chance Lose Price of lottery A fair price - $6 who will pay $5? 60% chance Win - $1M, 40% chance Lose Price of lottery A fair price - $600,000 who will pay $500,000? (Isn t this more like periviable resuscitation?) 7
