I have to agree w/ @rilescat - the BEST thing to happen to healthcare is to drop this ludicrous requirement on degrees\certifications and HEALTHCARE specific experience.
Any good technologist - and that should always include CIO\CTO's, should be able to play in any field well and pick it up as they go along.
The single worst thing any healthcare org looking to evolve past historic constraints could do would be to hire someone with more healthcare experience than enterprise IT experience (sorry docs, this means you) unless they have a proven track record that doesn't indicate bias.
While everyone should have a voice, the enterprise technologist hired as a CIO\CTO is the one that needs an equal vote as a partner to the business.
