Bar is VERY high for the Dr *Court [on behalf of the community] determines standard of care *Peer standards of care NOT a defence *Medical board even higher bar eg Medownick: CANNOT RELY ON HISTORY AS GIVEN BY PATIENT - must obtain WRITTEN history from previous Drs L. Kowal 2004 8

Chapel & Hart paraphrased If the case is unusual & If you the treating doctor know that there is someone else who has particular expertise in this sort of case then Part of the informed consent process must involve you telling the patient about this other doctor & letting the patient choose between you & the other doctor L.
