Using quality of life information to set priorities in health policy

Health care has as primary objectives extending life expectancy and improving quality of life in years prior to death. This paper offers a General Health Policy Model as a method for quantifying these outcomes. The model adjusts life expectancy for diminished quality of life, which is measured using a standardized instrument known as the Quality of Well-being (QWB) scale. The Well-year or Quality Adjusted Life Year (QALY) results from these analyses and serves as a single quantitative expression of health benefit. QALY units integrate side effects and benefits of treatment by combining into a single number, mortality, morbidity, and duration of each health state. Examples show the application of the model relevant to a variety of medical and public health problems, including diabetes, arthritis, AIDS, neonatal circumcision, and tobacco tax. It is suggested that the General Health Policy Model has advantages for guiding both individual and public health decisions.
