[What is cost effectiveness analysis?].

Abstract

Cost-effectiveness analysis (CEA) is an established economical form of analysis which, in public services, replaces the marketing mechanism. The questions which CEA attempts to answer are: Which form of medical technology is most economically effective where a given disease is concerned. Where and how must the medical technology be commenced. Which group of patients can benefit from a given form of medical technology? It is a prerequisite for employment of CEA that there is unanimity in advance about the object of an activity, eg. a given treatment or procedure in the diagnostic investigation. Several strategies may be employed to ensure that the aim is sufficiently wide: the limits may be explicit; goals may be established which compare years of life with quality of life, or several goals may be present in the goal. The predominant economical expression in CEA is alternative costs which must be sacrificed in order to carry out a certain activity. In order to estimate what is obtained by carrying out an activity, an expression of effect is essential. These are most frequently both of quantitative and also of qualitative character and may be subdivided into three categories: Alterations in the employment of resources. Alterations in production by society. Alterations in the conditions of health of the individual. Doctors are important decisions-makers and distributors of resources in the health services. The questions which a CEA can provide graduated answers to, are the questions that the doctor works with in clinical practice.(ABSTRACT TRUNCATED AT 250 WORDS)
