MediHandTrace data: visits of health-care workers to patient rooms and hand-hygiene compliance. a Number (left) and aggregate durations (right) of visits of HCWs to patient rooms per hour of the day, averaged over all days of the data collection, for all HCWs and for each HCW category. b Bipartite network of visits of HCWs to patient rooms. Each node represents either a HCW (top row) or a room (bottom row). The size of a node depends on its strength (aggregate duration of visits). The color of each HCW-node indicates its category, and red room-nodes indicate that the corresponding room was in “Clostridium” isolation during the whole data collection period. A link is drawn between a HCW and a room if the HCW visited the room at least once, and the link thickness depends on the aggregate duration of the visits. c Each bar gives the aggregated duration of all visits performed by a HCW. The total duration is split in different colors depending on the correct or incorrect use of HAS during the visits (correct use, use only before or after the contact with the patient, or no use at all).
