This document from Monitor.gov.uk summarizes procurement, patient choice, and competition rules for the UK health sector. It outlines Monitor's role in ensuring essential services are maintained, quality and efficiency are promoted, and choice and competition benefit patients. The key points are that commissioners must secure patient needs, improve quality and efficiency, act transparently and treat providers equally, and maintain records showing compliance. Commissioners should also consider how to improve services, ensure integration, and determine if choice of provider or competition could achieve better outcomes for patients.
