It is hereby declared by the Legislature of the State of Alabama that the availability of medical liability insurance at reasonable rates for the medical profession, medical institutions, and other health care providers is essential to provide adequate health services to the people of Alabama, and without such insurance, medical services by the medical profession may be curtailed, and that while the need for such insurance is increasing, availability is limited and likely to become increasingly so, unless remedial legislation is enacted. The Legislature further finds and declares that by reason of complicated and highly technical medical concepts, and the existence of sophisticated medical techniques, decisions with respect to optional procedures of diagnosis and treatment have become increasingly complex and are necessarily made on the basis of professional judgment, on which opinions may and often will reasonably vary. It is the purpose of this chapter to insure that the citizens of the State of Alabama are able to receive necessary health services by providing an environment in which the medical profession can be assured of medical liability insurance coverage and be afforded reasonable protection against personal liability for consequences proximately resulting from decisions with respect to diagnosis and treatment arrived at in the bona fide exercise of professional judgment.
