I agree that's it's silly to unnecessarily tie the providers hands by making the case more challenging than it need be, but the doctors ALSO have to right (if not the RESPONSIBILITY) to refuse to treat the patient if they feel the request is unreasonable and they don't possess the special skills required (i.e. bloodless surgery techniques) that will allow them to treat the patient's condition witout violating standards of care. If they don't feel they can do so, the doctor has an ethical and legal obligation to refer the patient to a collegue who CAN treat the patient, and presumably the local docs did this, and referred to this team of specialists who are being sued for taking on a difficult case.
Such providers would be wise to lower expectations of outcomes, carefully DOCUMENTING IN WRITING that the patient is tying their hands and understands that she may die as a result, since that helps protect them if the family or estate should decide to sue; a really-tight informed consent document discourages litigation, but cannot prevent it.
There apparently were sufficent grounds to question the medical care rendered under the circumstances (eg use of blood-thinners is an eyebrow-raiser, esp when bloodless techniques are to be used; it would require a 'risk vs benefit' analysis on the part of the providers), but in the end, the judges ruled that "reasonable efforts" were taken (which allows for SOME medical errors to have been made in rendering her care), and that the 'doctine of avoidable consequences' outweighs any errors in medical care that may have occurred, since the patient played a significant contributory role in making a difficult situation even worse by tying the hands of the providers by refusing blood, in the first place.
Judge Boonstra confirmed the patient's right to refuse medical treatment (for ANY reason, or what many others may see as BAD reasons, or even for NO reason at all), when he said:
"The choice was hers to make, whether for reasons of religion, or for altogether different reasons entirely, or in fact for no reason at all. But as in any aspect of life, where choices result in consequences, Ms. Rozier’s choice resulted in a consequence for her. Sadly, that consequence was her death."
So in essence, refusing blood allows more room for other errors to be made by the doctors, since the patient has knowingly signed away the right to complain if an undesirable outcome (like death) results.
