Visits are the core of a deputising service but not every request warrants one. The service has a policy setting out when a home or other visit is appropriate, how requests are triaged, how the safety of the location is assessed, what is offered when a visit is not safe or reasonable, such as clinic attendance, telehealth or emergency services, and the area it covers. The policy is explained to patients and to the practices served.
