For the hospital it means that visitors in this context are defined as volunteers and external service providers i.e. contractors, pharmaceutical and medical devices company representatives.
It is the presence of someone untrained in Hospital Policies and with no contractual responsibility to the trust, that presents an unquantifiable Risk for Hospital Management as per the Department of Health : NHS Code of Practice, July 2003 Management Regulations 1999 and the Data Protection Act. To date competence of the device representative is assumed rather than assured. Hospital managers are responsible for all those present within their departments and all patients with whom they may have contact. Theatres and clinical areas are already classified as areas of high risk to patients and therefore any non essential visitor may be assessed as an additional hazard in an already risk managed environment.
