None of this matters. If there's a bad outcome, and if cause/effect can be established, the jury will always side with the patient. If you were flying solo, you get named. If you consulted every service known to man, you all get named.
Where it might matter more, is if your hospital decides to challenge your credentials, and/or report you to the NPDB (if you made a mistake and did not consult).
For instance, I just DC'd PO AC in a patient (who was on it for pAF), because of recurrent GI bleeds and an Hgb of 4 (multiple admissions for bleeding). I did this without consulting cardiology. What a cowboy I am for using common sense. Now, in 6 months, if she throws a clot and strokes out, can I be sued? Absolutely, and the patient will be awarded. Will my hospital admonish me for not consulting cardiology (to decide whether PO AC should've been dc'd)? I dunno. I hope not. I guess we'll find out in 6 months.
