Community-Based Insurance
Community-based insurance is voluntary, not-for-profit health insurance run by a local community, whose members prepay small premiums into a shared fund.
Encyclopaedia
Explore comprehensive, evidence-informed explanations of key health economics concepts, including their development, application and relationships to other concepts. Published entries are validated through human expert review.
Concepts, entries and ontology terms
A concept page is a published entry on the wiki. Some concepts also have a full encyclopaedia article. The Health Economics Ontology (HEO) holds every concept, including dictionary terms without an article, so it is larger than the list of published pages. The knowledge graph shows how concepts relate to each other.
Community-Based Research
Community-based research is health research in which community members, organisations and researchers share every stage, from research questions to action.
Comorbidity
Comorbidity is any other condition a patient has alongside the index disease under study; in health economics it shifts costs, utilities and survival.
Comparator Selection
Comparator selection is the HTA step that decides which existing treatments a new technology is compared with, usually current care or what it replaces.
Competence
Competence is a person's legal authority to make their own decisions, such as consenting to treatment, as distinct from clinical assessment of capacity.
Compliance Programme
A compliance programme is the internal system a health care organisation uses to prevent, detect and correct breaches of health care law and payer rules.
Computerized Order Entry
Computerized order entry (CPOE) lets clinicians enter medication, test and other orders electronically instead of on paper, often with decision support.
Concentration Curve
A concentration curve plots the cumulative share of a health variable against the cumulative share of the population ranked from poorest to richest.
Concentration Index
The concentration index measures socioeconomic inequality in a health variable; a negative value means it is disproportionately held by the poor.
Concurrent Risk Adjustment
Concurrent risk adjustment predicts health care spending for a period from diagnoses recorded in that same period, often to adjust health plan payments.
Confidentiality
Confidentiality is the ethical and legal duty to protect identifiable patient information from disclosure unless there is consent or another lawful basis.
Conflict of Interest
Conflict of interest is a situation where a secondary interest, such as a manufacturer's payment, risks unduly swaying judgement in research, care or HTA.
Consensus Building
Consensus building is the use of structured group methods, such as Delphi panels, to agree judgements for guidelines and policy when evidence is thin.
Consumer Choice
Consumer choice is the economic theory of how people choose goods and services, including health care, to best satisfy their preferences within a budget.
Consumer-Directed Health Plan
A consumer-directed health plan (CDHP) is a US health plan pairing a high deductible with a tax-favoured account, such as an HSA or HRA, to pay for care.
Contact Tracing
Contact tracing finds and follows up people exposed to an infectious case so they can be tested, treated or quarantined before infecting others.
Continuity of Care
Continuity of care is the extent to which a patient's care over time is joined up, through a known clinician, shared information or a consistent plan.
Continuous Coverage
Continuous coverage is health insurance held with no gap longer than a set limit, often 63 days in US law, which can shorten pre-existing exclusions.
Continuous Quality Improvement
Continuous quality improvement (CQI) is an approach in which health services use systematic data and repeated tests of change to improve care.
Contract Theory
Contract theory studies how contracts, such as provider payment rules, can align incentives when actions or information are hidden or cannot be verified.
