Health care need and contracts for health services.

Assessments of health care needs are embedded in contracts for health services. Such contracts are the formal link between the identification of health care needs and the purchasing of services to satisfy those needs. They are a central part of the procedural relationship between the British health service (NHS) and the satisfaction of human needs. To evaluate contracts it is necessary to investigate this relationship. A number of headings under which it may be possible to begin to evaluate contracts are described, and the potential of a 'universalist' approach to interrogate contract-based decision-making is briefly discussed.
