Night work alone in unfamiliar places is hazardous. The service assesses the risks to its team in the after-hours period, at the clinic and on the road, and puts controls in place: screening of visit requests for known risks, drivers or chaperones for home visits, GPS tracking with check-in procedures and a response when a practitioner cannot be reached, duress alarms, secure parking and lighting at premises, and a clear right for any team member to decline or withdraw from an unsafe situation with the service arranging alternative care. Incidents are reported and reviewed.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
