This is part of why I really don't even want to see the medical form; let the student look at it, and if there are any YES answers, then don't even show me the form.....just give me the doctor's signature. The only purpose of the form is for me (the instructor or diveboat captain) to advise you (the student or diver) if you need a doctor's signature. The purpose of the form is NOT to have me evaluate your medical fitness. So give me back a medical form that is all NOs, or give me a doctor's OK for you to dive.
There's been lots of talk about liability, and how the medical release 'protects' the dive op.
It's extremely easy to see this all being flipped around...
Imagine, if you would, a large dive op in a popular area (think Florida Keys). They've got 50~100 customers/weekend, or 2500+ individuals/year.
Now, imagine that their office is burglarized, or someone leaves a filebox on the ground next to their car when they're bringing everything back from the boat, or a hurricane takes the roof off the office, scattering papers everywhere, or someone cleans out the 'old' files from a 'couple of years ago' and takes them to the local dump for recycling. Medical release papers. With names, and addresses, and details of medical conditions. Fluttering in the wind. Lining some birdcage. Scanned and on the internet. All those checkboxes saying "Yes" to recreational drug use making their way into prosecutor's offices, winding up in child custody disputes, etc.
Next, imagine the schools of hungry lawyers circling the wounded dive op, filing class action suits about invasion of privacy, etc.
In this world, the dive ops would be shredding those medical forms as fast as they could, and would refuse to ask for another one ever again!
As someone who works in healthcare, who deals with data covered under HIPAA regulations (American healthcare legislation dealing with protection of personal health data, many other countries have similar--or more stringent--privacy regulations), I'm amazed and uncomfortable about the information requested on the medical release and the care (or lack thereof) with which that information is handled.
I'd be fine with the dive op explaining each question on the form with me in advance, discussing with me about how each question is related to specific risks about diving, then simply asking if I would say "yes" to any of them -- that protects them and helps educate divers.
I'd be fine with signing a statement to the effect that I am either unaware of any conditions that require a medical release, or I have gotten the medical release.
