(b) Documents, incident reports or records otherwise available from original sources shall not be immune from subpoena, discovery or use in any such judicial or administrative proceeding merely because they were presented to such committee in connection with its proceedings. Nor shall the proceedings, reports, findings and records of a medical peer review committee be immune from subpoena, discovery or use as evidence in any proceeding against a member of such committee to establish a cause of action pursuant to section eighty-five N of chapter two hundred and thirty-one; provided, however, that in no event shall the identity of any person furnishing information or opinions to the committee be disclosed without the permission of such person.
