Defining Quality Health Care

In order for Quality Informatics to address the quality of health care, it is necessary to first define the phrase "quality health care". The father of health quality assurance, Avedis Donabedian said that high quality health care consisted of "that kind of care which is expected to maximize an inclusive measure of patient welfare, after one has taken account of the balance of expected gains and losses that attend the process of care in all its parts." (1)

The American Medical Association described high quality health care as that "which consistently contributes to improvement or maintenance of the quality and/or duration of life." (2)

Lohr and her committee were tasked by the IOM to define quality health care and their definition was "the degree to which health services for individuals and populations increase the likelihood of desired health outcomes and are consistent with current professional knowledge." (3)

The fact that multiple definitions of health care quality exist is an indication that this is a very complex subject to try to define in a few phrases. Donabedian (4) further described attributes of quality health care, which he called the "Seven Pillars of Quality":

1. Efficacy: the ability of care, at its best, to improve health;

2. Effectiveness: the degree to which attainable health improvements are realized;

3. Efficiency: the ability to obtain the greatest health improvement at the lowest cost;

4. Optimality: the most advantageous balancing of costs and benefits;

5. Acceptability: conformity to patient preferences regarding accessibility, the patient-practitioner relation, the amenities, the effects of care, and the cost of care;

6. Legitimacy: conformity to social preferences concerning all of the above; and

7. Equity: fairness in the distribution of care and its effects on health.


In a similar fashion, Maxwell (5) defined the six dimensions of quality health care:

1. Access to services

2. Relevance to need (for the whole community)

3. Effectiveness (for individual patients)

4. Equity (fairness)

5. Social Acceptability

6. Efficiency and Economy

With multiple dimensions and attributes ascribed to quality care, it is of note that physicians themselves tend to judge the quality of care on the basis of the technical sophistication of the health care delivered, and placed an emphasis on the quality of the interaction between the physician and the patient.(8)

What Measurements to Assess?

The many descriptions and factors involved in producing quality health care makes it difficult to determine which of these attributes or characteristics should be assessed? A seemingly natural candidate for
