Cost-effectiveness analysis could be a kind of economic analysis that compares the relative prices and outcomes of various courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis that assigns a cost to the live of result. Cost-effectiveness analysis is commonly employed in the sphere of health services, wherever its going to be inappropriate to legitimize health result. generally the CEA is expressed in terms of a magnitude relation wherever the divisor could be a gain in health from a live and therefore the dividend is that the value related to the health gain. The foremost unremarkably used outcome live is quality-adjusted life years. Cost-utility analysis is analogous to cost-effectiveness analysis. Cost-effectiveness analyses area unit typically pictured on a plane consisting of four-quadrants, the value painted on one axis and therefore the effectiveness on the opposite axis. Cost-effectiveness Analysis focuses on maximizing the common level of an outcome, spatial arrangement cost-effectiveness analysis extends the core strategies of cost effectiveness analysis to include issues for the distribution of outcomes yet as their average level and create trade-offs between equity and potency, these additional refined strategies area unit of explicit interest once analyzing interventions to tackle health difference.
