| Abstract: | A comparative experience of 474 patients with primary carcinoma of the colon and rectum has been evaluated in several hospital settings, with particular respect to patient populations, geographic distribution, and surgical characteristics. The differences and similarities are interpreted with caution but may provide a format by which significant objective determinants become the basis for subsequent assessment of quality care in an illness which is prevalent and amenable to relatively standardized operative management. No difference in quality of medical care provided was detectable across the sociologic and geographic boundaries studied. Notable increases in extent of neoplasm and severity of co-existent illness in the urban, "indigent" population adversely influenced both short and long-term mortality rates. |
