Abstract

Much research aimed at developing measures for normative criteria to guide the assessment of healthcare resource allocation decisions has focused on health maximization, equity concerns and more recently approaches based on health capabilities. However, a widely embraced idea is that health resources should be allocated to meet health needs. Little attention has been given to the principle of need which is often mentioned as an alternative independent criteria that could be used to guide healthcare evaluations. This paper develops a model and indicator of need satisfaction that aggregates the health needs of a population in a particular time period into a single measure that weights individual health needs by the severity of their ill health. The paper provides a first step towards formalizing the principle of need as a measurable objective for healthcare policy and we discuss some challenges for future research, including incorporating the duration of time into need-based health evaluations.
