Because the candid and conscientious evaluation of clinical practices is essential to the provision of adequate health care, it is the policy of this State to encourage peer review by health care providers. Therefore, while serving upon any committee whose purpose, directly or indirectly, is internal quality control or medical study to reduce morbidity or mortality, or for improving patient care or physician services within a hospital duly licensed under the Hospital Licensing Act, or within a professional association of persons licensed under this Act, or the improving or benefiting of patient care and treatment whether within a hospital or not, or for the purpose of professional discipline, any person serving on such committee, and any person providing service to such committees, shall not be liable for civil damages as a result of their acts, omissions, decisions, or any other conduct in connection with their duties on such committees, except those involving wilful or wanton misconduct.
Information considered shall be afforded the same status as is information concerning medical studies by Part 21 of Article VIII of the "Code of Civil Procedure", as now or hereafter amended.
