We need to change from a required medical sign off (which is only required if the diver has either clear medical issues OR is totally honest on the form) to self-regulation with adequate and understandable information so that the diver will seek evaluation by the appropriate level of medical provider if there are issues.
To understand why things are done the way they are, it's key to look at the stakeholder interests involved.
1.) The recreational diver - in theory, this is what it's all about. In reality, bull. Supposedly there's this black and white 'fit to dive or not fit to dive' dichotomy, it's practical for someone to make that call, and the diver, his family, his doctor, the dive op., basically everyone agrees with this and the goal is to use paperwork to trigger this determination, which will be made by a qualified and competent where diving clearance is concerned medical professional and everyone will accept that accurate determination, including the diver. Bull.
2.) The dive op. - doesn't want to get sued (which can be a terrible ordeal, even if they 'win' - and even a win can be a pyrrhic victory - after all, what do they 'win?'). Staff don't want to have to deal with avoidable emergencies. If a poorly regulated diabetic passes out at 90 feet and by the time the guide notices him he's sinking past 140, it's late in the dive and everybody's on nitrox... So they need to exclude higher risk divers, or at least secure full deniability in case one dies on their watch.
3.) The agencies - I don't hear this angle much, but I imagine PADI, SSI and others need some kind of medical 'informed consent' effort to defray risk.
4.) The health care professionals you seek clearance from don't sign off on clearances for a living, so they're taking on substantial risk for little if any gain. If you die, people may come after them. How many general practice physicians are knowledgable about diving medicine?
The problem is 2-fold. First off, the interests of 2.) and 3.) drive policy. Yes, 1.) is part of it...but I think lawyers have more to do with driving this than doctors. Second...we have the issue of autonomy.
In a nutshell...I decide for myself whether I'm fit to dive in a given scenario. I'll wish to have the info. available to make an informed decision, including access to professional consultation and expert articles if needed. I will not surrender that decision to some 'big brother,' such as whoever I'm referred to. I recognize that checking 'yes' on one of those clearance forms will result in denial of service until I submit to formal evaluation and surrender that decision.
And if I did? Would I seek out some distant dive medical professional? No. I'd take the form to my family doctor, explain away any concerns I considered trivial, and likely get a clearance...that one could likely argue was largely a clearance by me. If he wouldn't do it, I'd shop around for someone who would.
In the real world, many divers are in their 40's and older. Particularly the distant dive trip takers, who can take a week off and pay for airfare, hotel, diving, etc... This demographic often has pretty well-managed fairly minor medical issues - high cholesterol, hypertension, enlarged prostate, arthritis, vision impairment, etc...
Bottom Line: You check 'yes' to anything on a medical clearance form and you may well have surrendered your autonomy to another decision maker you may disagree with, and put yourself out time, effort and money to secure a clearance you may've obviously not needed medically and the quality of which may be poor. But since the needs, wants and personal liberty of the diver don't seem to be the primary policy drivers...don't expect much change.
