The total costs of illness: a metric for health care reform.
Systems thinking is a fundamental element of quality management and should be a fundamental element of health care reform. An implication of systems thinking is that one aim of health care should be to minimize the total costs of illness, not simply the direct medical expenditures. If we are to continue to improve health care over time, we should measure its impact on the total costs of illness to the patient, family, employer, and society. Thus a system of measurement is needed that quantifies total costs of illness and also suggests how these constituencies can collaborate to improve processes and reduce total costs. This article introduces the total costs of illness concept, contrasts it with societal costs of illness, describes a measurement system we developed to quantify it, and describes a case study examining the total costs of back injury illness to employers. We found that medical expenditures accounted for less than half of the total costs of illness, the average total costs of illness varied by over 350 percent among employers, and a simple metric (days off work) explained 62.5 percent of the variance in total costs of illness.
