QUALITY ASSESSMENT is defined by the ADA as the measure of the quality of care provided in a particular setting.
QUALITY ASSURANCE is the assessment or measurement of the quality of care and the implementation of any necessary changes to either maintain or improve the quality of care rendered.
The differences in these definitions are important; quality assessment is limited to the appraisal of whether or not standards of quality have been met, whereas quality assurance includes the added dimension of corrective action to improve the future situation.
One frequently used approach to quality assessment and assurance builds on the concepts of structure, process, and outcome, as described by Donabedian.*
This model is based on the idea that while the outcome of treatment is of primary importance, a desirable outcome is more likely if the structural arrangements, such as well-designed treatment facilities, proper equipment, and appropriately and properly trained staff, meet adequate standards. A good outcome is also more likely if the processes used, such as diagnostic methods, treatment planning, record keeping, and the treatment procedures themselves follow recognized protocols.
Other dimensions of quality that are frequently mentioned, in addition to the technical quality of restorative procedures, are appropriateness of care, access to care, costs of care, and patient satisfaction. * Donabedian A.
