A former Bristol Hospital employee and patient who claims she was violently sexually assaulted by an outside surgeon there in 2011 has sued the doctor and the hospital, with the latter unsuccessfully attempting to dismiss all claims.

Judge Stefan Underhill issued a mixed ruling Monday on the hospital’s motion to dismiss, allowing the suit to move forward on three of four counts. He rejected a count alleging negligence through an agent or supervisor but let stand claims of negligence and negligence in hiring, retention and supervision.
