What researchers measure

Primary outcomes

  1. Reoperation Rate

    Differences in the rate of reoperation due to cancer positive margins

    Time frame: 2-30 days post Breast Surgery

Secondary outcomes

  1. Margin status of intraoperative specimen vs. postoperative pathology assessment [Clinical Performance]

    To observe real life clinical performance of the HLS and accessories when used intraoperatively

    Time frame: 0-30 days post Breast Surgery

  2. System Usability Scale (SUS) of the IVD device and accessories [Usability]

    To survey usability of the HLS and accessories when used intraoperatively

    Time frame: Only during the time of the breast surgery

  3. Change in hospital cost with or without IVD device and accessories [Economic Impact]

    To evaluate the economic impact for the hospital/payer of the reoperation rate

    Time frame: 30 days post surgery date

  4. Incidence of adverse device effects [Safety]

    Incidence of adverse device effects during surgery

    Time frame: Only during the time of the breast surgery
