An equation of health: Role of transparency and opacity in developing healthcare efficacy measures and metrics

Purpose - This article aims to present an equation of health to allow measurement and more precise comparison of what is more or less effective in promoting health or managing ill health. It builds upon and extends a prior report (JMD, Volume 25 Number 10, 2006, pp. 981-995). Design/methodology/approach - Applying basic scientific methods and empiric observations, the equation proposed in this article is a state of the current science. Such an equation allows for more systematic and predictive comparison of health initiatives. Findings - The pace of scientific progress is outstripping our institutional adaptive response mechanisms. An approach to the causes of ill health appears more promising than re-configuration of current disease reactive, symptom treatment care. This paper starts from first principles and builds a model that results in an equation of health. Research limitations/implications - Refinement of the model and replication by others are needed to fully determine the predictive value of this approach. Practical implications - The opportunity to reduce costs while also reducing adverse events, healthcare morbidity and morality. Originality/value - This article calls attention to areas of opportunity to fund out of savings the transition from our current "sick care" system to a health promotion/proactive prevention approach to caring.
