title: Quality of care of colorectal cancer patients in general hospitals: diffusion and impact of management guidelines.
abstract: Over the last ten years the Italian National Research Council (C.N.R.) has launched an educational program aimed at favoring the delivery of the most up to date care for cancer patients in community hospitals. Among various tumors for which this effort was undertaken, management guidelines for colorectal cancer were developed in 1978 by a multidisciplinary team of national experts and reported in booklets distributed nationwide under the aegis of the Colorectal Cancer Task Force. In 1988, the C.N.R. funded an evaluation to learn whether: a) the guidelines were widely diffused in the target physician populations; b) their content was accepted by those who received them and, c) practice patterns were consistent with the recommendations in the guidelines. Overall results indicate only a limited effect. Despite clear evidence of a positive self-selection in the physicians' survey, guidelines were familiar to only 47% of responders. Although acceptance of at least some specific recommendations was good among doctors aware of the guidelines (greater than or equal to 60% responders), this finding loses relevance since a not negligible proportion of those not aware of them had the same convictions. Finally, analysis of practice patterns showed serious deficiencies (mostly in terms of thoroughness of operative staging) even in centers where more widespread knowledge of the guidelines should have led to better quality of care. The paper also discusses the comparability of our findings to results of a similar evaluation carried out in the U.S.A. Our results underscore the importance of analyzing the process of diffusion in any assessment of interventions based on knowledge dissemination.
