WELL-ESTABLISHED QUALITY-OF-CARE MEASURES

In its April 1999 report, the board noted the absence of a core set of quality measures for cancer care and recommended that such a set be developed through a coordinated public–private effort. While there is no accepted set of measures, several “process” quality measures have been used to assess cancer care (Table 5.1). Process quality refers to what providers do for patients and how well they do it, both technically and interpersonally. Effective process measures are identified through evidence from appropriately designed studies (e.g., clinical trials) that show a link between a particular process of care and better outcomes. Once this link has been established, systems can be put into place to monitor adher-
