Considerable transformation is occurring in healthcare globally with organizations focusing on achieving the quadruple aim of improving the experience of care, the health of populations, and the experience of providing care while reducing per capita costs of health care. In response, health care organizations are employing performance measurement and quality improvement methods to achieve the quadruple aim. Despite the plethora of measures available to health managers, there is no standardized data set and virtually no indicators reflecting how patients actually experience the delivery of fundamental care, such as nutrition, hydration, mobility, respect, education, and psychosocial support. Given the linkages of fundamental care to safety and quality metrics, efforts to build the evidence base and knowledge that captures the impact of enacting fundamental care across the health care continuum and lifespan should include generating a routinely collected data set of relevant measures. This paper provides an overview of the current state of performance measurement, key trends, and a methodological approach to leverage in efforts to generate a standardized data set for fundamental care.
