Cost and quality are the two essential “factors of production” in value for money in healthcare. As such, price transparency, whether hospital or health plan, is not the end, but a means to the end. Executive Order 13877 notes that “to make fully informed decisions about their healthcare, patients must know the price and quality of a good or service in advance,” which explains its declaration of the need for a Health Quality Roadmap. However, the consultant-speak in the graphic above from CMS’s Centers for Clinical Standards and Quality – “Improve Quality, Protect Safety” – implicitly reveals the truth of the matter: medicine is a mix of science and art. A CABG is a fine example: the science of how and why a coronary artery bypass will work, and the art revealed in the surgeon’s hands that sew the blood vessel into the artery and aorta.
It is axiomatic that beauty is in the eye of the beholder, as it is in Justice Stewart’s definition of pornography that “I know it when I see it.” Both axioms apply to healthcare quality. For a two-view ankle X-ray, the technician’s only patient instruction – “Don’t move” – reflects the sole quality metric for the scan. In contrast, proton beam therapy requires a medical physicist for treatment planning, dosing and safety.
As von Mises noted, “it is a serious blunder to disregard differences in the quality of the commodity in question,” which is especially true for healthcare services. A rigorous approach to quality measurement is required, and it is hard, as England’s National Health Service has learned:
“The traditional accounting framework for discussing value for money is…[f]inancial inputs (in the form of costs) are converted into physical inputs (such as labour and capital). The success of this conversion is often referred to as the ‘economy’ with which inputs are purchased. Physical inputs are in turn converted into physical outputs (such as an episode of hospital care). The relationship between physical inputs and outputs is often referred to as ‘efficiency’. Depending on the quality of care, the physical outputs then create eventual outcomes, for example, increases to the quality and length of life. The success of this conversion is referred to as ‘effectiveness’.
It is conventional to consider various value for money measures under these headings. For example, the traditional measure of ‘length of stay’ for a hospital episode is an efficiency measure as it indicates the level of physical inputs (bed days) required to produce a physical output (an ‘episode’). In contrast, the post-operative mortality rate is a measure of the quality of that output and therefore a signal of effectiveness. The holy grail of value for money is therefore cost-effectiveness: the ratio of outcomes to inputs. For example, the ‘cost per quality adjusted life year’ used by the National Institute for Health and Clinical Excellence (NICE) to assess new technologies is a cost-effectiveness ratio, and the recent efforts to develop a single number measure of NHS productivity represent an attempt to move from the piecemeal assessment of indicators of economy, efficiency and effectiveness towards a more comprehensive measure of cost-effectiveness…
Recent work in estimating system productivity has developed innovative approaches, such as seeking to incorporate measures of quality alongside measures of inputs and activity…[which] implies a desire to incorporate measures of effectiveness into the value for money analysis. However, because of the difficulties associated with defining and measuring quality, little consensus has yet to emerge as to the ‘correct’ or most appropriate approach.
…
Any assessment of a health service ought to examine indicators of the value of the ‘output’ it creates. Traditionally, two classes of outcome are considered important in healthcare: clinical outcomes expressed in terms of the health gains created by the system, and the quality of the patient experience, independent of health outcomes, expressed in concepts such as ease of access to care and responsiveness.
Some health outcomes indicators – such as life expectancy rates, infant mortality rates and cancer mortality rates – are available. However, improvements in these are a function of many factors over which the NHS often has little influence. The relative scarcity of readily accessible outcome data specific to the NHS forces any analysis to rely heavily on process indicators, on the assumption that they provide a reasonable proxy for health outcomes.”5
CMS has done little to delineate between subjective and objective quality in healthcare. Moreover, CMS does not acknowledge that quality is frequently completely irrelevant in many of its “shoppable” services as long as a phlebotomist can hit a vein. Where quality is irrelevant, value for money depends primarily on cost, though as a general principle healthcare services that don’t involve quality – like a strep throat swab – are relatively inexpensive. Where quality is essential but economically intangible, value for money is an elusive concept.
Since the 1999 publication of To Err is Human in 1999 and the 2007 release of the Triple Aim, CMS has implemented a vast quality reporting framework at incalculable system cost in the form of Quality Measures, HEDIS Measures, Consumer Assessment of Healthcare Providers & Systems, etc. Like Seinfeld’s The Car Reservation episode, creating a reporting framework and enforcing a reporting framework are not the same thing, and neither is the same as measuring health outcomes. After 20 years, CMS has abundant evidence to demonstrate the fallacy of assuming that process measures “provide a reasonable proxy for health outcomes.”
There is no way to calculate value for money in healthcare without transparency about cost and quality.
If CMS or health economy stakeholders cannot measure healthcare quality, then value for money in healthcare is unachievable…which may leave every health economy stakeholder to restructure its business model to survive under price caps. Of course, if CMS cannot measure healthcare quality, then its quality reporting framework is logically part of the oft-cited administrative waste in healthcare.
America has a history of doing challenging things. Figuring out how to measure healthcare quality is challenging, but it is the most important initiative for America’s fiscal health, which is inextricably linked to the health economy, which continues to grow at an unsustainable rate.
