This is the reason I don't sign them. I'm a licensed M.D. board certified in two specialties that cover most of the questions on the medical form. I have declined signing these forms. If I were to sign one, the diver would have had to answer all the questions yes or no, and I would have done a complete history and a comprehensive physical exam.
But I still won't sign it. It may not be the diver, a trusted, well-liked patient or friend, that I'm afraid of. It's his family members that I don't know and their plaintiff's attorney that will go after me.
I would consider any medical form that doesn't have the questions on the first page answered yes or no, even if signed by a doctor, to be incomplete because I wouldn't know if the signing doctor was aware of any medical conditions that might exist. Sure, the applicant can answer no to everything, but then some responsibility rests on him/her.
PADI may obfuscate the issue, but I can superimpose my own criteria if I am to consider signing a medical form or accepting one as a boat captain or instructor (I am neither).
Dunno. I mean just like diving, ever doctor has to come up with their own level of comfort with risk. I would never suggest that you take any action in the course of your medical practice that you were uncomfortable with. And maybe I'm misunderstanding what you are saying - but I take your post to mean that you would never sign one because of the medicolegal risk involved? Or do you mean you would only sign it if they answered all the questions yes or no on the first page? Sorry if I'm not understanding so well - correct me if I'm wrong.
But if you won't sign them under any circumstances - and you are probably far more qualified than me - who will sign them? I guess you can just say that some other doctor can do an H&P and make a clinical judgement about whether or not that patient is fit to dive, but that's sort of kicking the can down the road. Patients with many of those chronic medical conditions on the form are entitled to dive if they aren't at significant excess risk, right?
You do a history. You do an exam. You make a judgement that this person has a reasonably low risk of a medical event while diving despite the fact that he answered yes to one of those questions. You aren't lying or fudging anything, you are giving your best clinical judgement. Are you guaranteeing that this person will never suffer a medical problem while diving? Of course not. How could you ever do that?
Every day in my practice I make judgements that might be wrong. I reassure parents of newborn babies that their child's airway is OK, but I could miss a congenital airway anomaly on an office exam. Still, I have to move forward, I have to give each patient my best effort, even though I'm human and fallible. So while I don't sign these often, I would still do it if I felt comfortable that I had adequately evaluated the patient...
