Health State Valuation
Health state valuation is the measurement of people's preferences for described health states, giving the utility values used in cost-utility analysis.
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.
Health System Building Blocks
Health system building blocks are the six components of a health system named by WHO, such as financing, workforce and medicines, used to plan investment.
Health System Financing
Health system financing is how a country raises money for health, pools it to share risk and buys services, shaping access and financial protection.
Health System Organization
Health system organisation is the way a health system's regulators, funders, purchasers and providers are arranged, linked and held to account for care.
Health Technology Adoption Curve
A health technology adoption curve shows how use of a new medicine or device grows over time, usually S-shaped: slow, then rapid, then levelling off.
Health Technology Assessment
Health technology assessment (HTA) evaluates the clinical, economic, social and ethical effects of a drug, test, device or procedure to guide its use.
Health-Adjusted Life Year
Health-adjusted life years (HALYs) are a family of measures, such as the QALY and DALY, that combine length of life and health status in one number.
Health-Related Quality of Life
Health-related quality of life (HRQoL) is the effect of illness and treatment on a person's physical, psychological and social life, used to weight QALYs.
Healthcare Accreditation
Healthcare accreditation is external review of health services against published standards by an accrediting body, with public recognition if they comply.
Healthcare Production Function
A healthcare production function gives the maximum care output, such as visits or hospital episodes, obtainable from given staff, capital and technology.
Healthy Life Expectancy
Healthy life expectancy (HLE) is the average number of years a person is expected to live in good health, given current rates of death and ill health.
Healthy Year Equivalent
A healthy year equivalent (HYE) is the number of years in full health a person values as highly as a lifetime health profile, an alternative to the QALY.
Hedges' g
Hedges' g is a standardised mean difference, the gap between two group means divided by their pooled standard deviation, corrected for small-sample bias.
Heterogeneity Assessment
Heterogeneity assessment evaluates the nature, extent, and possible causes of differences in effects or outcomes across studies, populations, or settings.
Heterogeneous Treatment Effect
A heterogeneous treatment effect is variation in a treatment's benefit or harm across patients, so the average can mislead treatment and funding decisions.
Hidden Markov Model
A hidden Markov model (HMM) is a Markov model of disease progression whose true states are unobserved and inferred from error-prone tests or markers.
Hierarchical Condition Category
A hierarchical condition category (HCC) groups related diagnosis codes by severity so that CMS risk models can predict an enrolee's relative future cost.
Hierarchical Model
A hierarchical model represents observations or parameters at multiple related levels and estimates variation within and between those levels.
Hierarchical Testing
Hierarchical testing controls false positives across trial endpoints by testing them in a prespecified order at full alpha, stopping at the first failure.
Hierarchy of Diagnostic Efficacy
The hierarchy of diagnostic efficacy is Fryback and Thornbury's six-level model for judging a test, from image quality and accuracy to societal value.
