If the Commissioner of Public Health finds that the health, safety or welfare of any patient or patients served by an institution, as defined in subsections (d) and (e) of section 19a-490, imperatively requires emergency action and he incorporates a finding to that effect in his order, he may issue a summary order to the holder of a license issued pursuant to section 19a-493 pending completion of any proceedings conducted pursuant to section 19a-494. These proceedings shall be promptly instituted and determined. The orders which the commissioner may issue shall include, but not be limited to: (1) Revoking or suspending the license; (2) prohibiting such institution from contracting with new patients or terminating its relationship with current patients; (3) limiting the license of such institution in any respect, including reducing the patient capacity or services which may be provided by such institution; and (4) compelling compliance with the applicable statutes or regulations of the department.
