Black boxes in operating rooms

Black boxes are now beginning to be installed in the operating rooms of some hospitals  as a way to increase accountability and to cut down on surgical errors.
                                             Black boxes can record conversations and procedures in operating rooms.
                                              Black boxes monitor operating room traffic.In operating rooms,doors are often opening and closing during surgeries.Visitors sometimes drop into operating rooms and ask medical staff  'How was your weekend','Did you catch the hockey game last night'?,etc.These distractions can result in errors big or small.
                                                    Now new operating room procedures are being instituted in hospitals in 2019 in many cities.Administrators are setting up distraction-free zones in operating rooms and medication dispensing rooms to cut down on surgical errors and drug substitution errors or dosage errors.
