Health economics
The study of how scarce resources are allocated among alternative uses for the care of sickness and the promotion, maintenance, and improvement of health. This includes the study of how health care and health-related services, their costs and benefits, and health itself are distributed among individuals and groups in society.
Impact Evaluation
“Objective test of what changes have occurred and the extent to which these can be attributed to the policy” [intervention/service]
Magenta Book (2011)
http://gov.uk/government/publications/the-magenta-book
Incremental cost-effectiveness ratio (ICER)
Obtained by dividing the difference between the costs of the two interventions by the difference in the outcomes (i.e., the extra cost per extra unit of effect).
Logic Model
“Logic models describe the relationship between an intervention’s inputs, activities, outputs, outcomes, and impacts”
https://www.gov.uk/government/publications/the-magenta-book.
“A logic model is a systematic and visual way to present and share your understanding of the relationships among the resources you have to operate your program, the activities you plan, and the changes or results you hope to achieve”
https://wkkf.issuelab.org/resource/logic-model-development-guide.htm
Natural Experiments
“work best in circumstances where a relatively large population is affected by a substantial change in a well-understood environmental exposure, and where exposures and outcomes can be captured through routine data sources, such as environmental monitoring and mortality records”

Outcome Measure
“changes (desirable and undesirable) in individuals and populations that are attributed to” intervention / service.
“denotes the effects of care on the health status of patients and the population”

Participatory Evaluation
“Improve program implementation and outcomes by actively engaging all stakeholders in the evaluation process”
W.K. Kellogg Foundation (2010) Evaluation Handbook

Perspective
The point of view from which an analysis is carried out. The NHS perspective considers costs and benefits from the point of view of the healthcare system.
Process Evaluation
“a study which aims to understand the functioning of an intervention, by examining implementation, mechanisms of impact, and contextual factors”
UK Medical Research Council (MRC) guidance (2014) Process Evaluation of Complex Interventions
mrc.ac.uk/documents/pdf/mrc-phsrn-process-evaluation-summary-guidance
Process Measure
“interactions between healthcare practitioner and patient; a series of actions, changes, or functions bringing about a result (such as mammography screening rate)”
“denotes what is actually being done in giving and receiving care”
