Cost-Benefit Analysis
Cost-benefit analysis is a full economic evaluation that values the differences in the costs and consequences of healthcare alternatives in monetary terms so that their net social value can be compared.

Cost-Consequence Analysis
An evaluation that displays each option’s costs and range of outcomes separately, allowing decision-makers to consider them without a combined summary result.
Cost-Effectiveness
A property describing the relationship between an intervention's cost and its health effect relative to an alternative, usually summarised as an incremental cost-effectiveness ratio.
Cost-Effectiveness Acceptability Curve (CEAC)
A graph plotting the probability an intervention is cost-effective against a range of possible values for the cost-effectiveness threshold.
Cost-Effectiveness Acceptability Frontier
A curve showing, across willingness-to-pay thresholds, the probability that the option with the highest expected net benefit at each threshold is truly optimal.
Cost-Effectiveness Analysis
Cost-effectiveness analysis compares healthcare alternatives by relating differences in their costs to differences in outcomes measured using the same natural unit, such as cases prevented or life-years gained.
Cost-Effectiveness Frontier
The set of non-dominated interventions on a cost-effectiveness plane, connecting options offering the best available combination of cost and effect.
Cost-Effectiveness Plane
A graph plotting an intervention's incremental cost against its incremental effect relative to a comparator, cost on the vertical axis and effect on the horizontal.
Cost-Effectiveness Threshold
A cost-effectiveness threshold is a benchmark used to judge whether the additional health produced by an intervention is worth its additional cost, usually expressed as an amount per QALY or another unit of health outcome.
Cost-Minimisation Analysis
Cost-minimisation analysis compares the costs of healthcare alternatives only after reliable evidence shows that their relevant outcomes do not differ meaningfully.
Cost-of-Illness Study
A cost-of-illness study is a descriptive economic analysis that identifies, measures and values the healthcare resource use, patient and caregiver costs, productivity losses and other economic consequences attributable to a disease, injury or risk factor in a defined population and period.
Cost-to-Charge Ratio
A ratio, typically from hospital accounting reports, used to convert billed charges into an estimate of the actual cost of providing a service.
Cost-Utility Analysis
Cost-utility analysis is a full economic evaluation that compares healthcare alternatives by relating differences in their costs to differences in preference-weighted health outcomes, most commonly quality-adjusted life years.
Cross-Price Elasticity
A measure of how the quantity demanded of one good responds to a price change in a different good, such as a substitute or complement.
Crosswalk
A statistical mapping converting health state scores from one version of an instrument to an equivalent score on another version.
Current Ratio
A financial ratio calculated as current assets divided by current liabilities, used to assess an organisation's ability to meet short-term obligations.
D-Efficient Design
An experimental design for a discrete choice experiment built to minimise the statistical variance of estimated attribute parameters for a fixed number of tasks.
DALY Calculation Method
The methodology used to compute disability-adjusted life years, combining years of life lost to premature death with years lived with disability, weighted by severity.
Days Cash on Hand
A financial ratio measuring how many days an organisation could cover its operating expenses using only available cash reserves, without extra revenue.
Deadweight Loss
The loss of total economic welfare when a market does not operate at its efficient equilibrium, such as due to a tax or monopoly.
