The board of trustees of any hospital organized under this chapter is authorized to promulgate rules and regulations governing the granting and revoking of privileges to treat patients in the hospital. Such rules shall provide that only those persons licensed to practice medicine and surgery, i.e., medical doctors and osteopathic physicians, may be granted privileges to treat patients in the hospital. Such doctors and physicians may retain their privileges so long as they comply with the rules and regulations of the board of trustees.
