Efficiency indicators (the relationship of inputs to outputs) measure how efficiently the outputs of a service were achieved. Technical efficiency indicators measure how well services use their resources (inputs) to produce outputs. Government funding per unit of output delivered is a typical indicator of technical efficiency. Allocative efficiency considers the use of resources across different care/treatment domains and strategic options, including in hospitals and primary care settings. Whilst indicators of allocative efficiency are not currently well developed in health care, they will be a focus for future development.
