Toxicity Period (TOX)
Toxicity period (TOX) is the Q-TWiST state for time with the treatment toxicity an analysis counts, often grade 3 or worse, weighted by its own utility.
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.
Treatment Administration Cost
Treatment administration cost is the cost of giving a medicine to a patient, such as nurse and chair time and consumables; it varies by route.
Utilisation Review
Utilisation review (UR) is a payer's check of whether a patient's care is necessary and appropriate, used to curb unnecessary use and contain costs.
Utility
Utility is a numerical measure of preference; in health economics, a health utility values a health state on a scale where 1 is full health and 0 is dead.
Value Set
A value set is the set of utility weights, from a general public valuation study, that scores every health state an instrument such as EQ-5D describes.
Value-Based Purchasing
Value-based purchasing is when a health purchaser ties provider payment or contracts to measured quality and outcomes, as in Medicare's hospital programme.
Variation
Variation is the spread of a measured quantity, such as cost, service use or outcome, across patients, providers, areas or time periods in a health system.
Visual Analogue Scale
The visual analogue scale (VAS) is a line, usually scored 0 to 100, on which people rate their own health or a health state between two labelled ends.
Wellbeing or Capability Instrument
Wellbeing or capability instruments are outcome measures, such as ICECAP, WEMWBS or EQ-HWB, that capture benefits beyond health that EQ-5D QALYs miss.
Years Lived with Disability
Years lived with disability (YLDs) measure non-fatal health loss, usually as prevalence times disability weight; adding years of life lost gives the DALY.
Years of Life Lost
Years of life lost (YLL) measure premature mortality as deaths times standard remaining life expectancy at the age of death, the fatal part of the DALY.
