48 Screening for Colorectal Cancer KCE reports vol.45 4 GUIDELINES ON COLORECTAL CANCER SCREENING AND SURVEILLANCE 4.1 INTRODUCTION A quick explorative Medline search, focusing on colorectal cancer combined with either screening or surveillance and with addition of the search term guideline$ for the field publication type yielded 45, respectively 24 citations if restricted to the years 2000 2006. Subsequently we searched additional guidelines sources (see appendix for details). We retrieved guidelines on average risk screening as well as on surveillance and management of groups at increased risk of colorectal cancer, however limited to the years 2000 - 2006. Older or rescinded guidelines, as well as guidelines and recommendations in other languages than English, Dutch or French were disregarded. Excluded were also guidelines exclusively restricted to treatment of CRC or genetic testing for hereditary colorectal cancer. As a result of those searches, 20 full-text guidelines & recommendations were obtained, including, for some of them, their NGC appraisals. 4.2 GENERAL PRINCIPLES Clinical practice guidelines (CPG) are defined as systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances (Oxford Centre for Evidence-Based Medicine - CEBM169, 170). 1. Good CPG provide graded recommendations about a specific health problem, based on the best evidence available at the time they are derived by means of a systematic review of the scientific literature and representing consensus opinion of experts gathered 171 through Consensus development conferences, Expert Consensus Committees, Delphi method, Nominal Group Technique, etc. The former (the systematic review) implies the application of rating schemes for appraisal of the strength of reviewed evidence 172, 173, the latter (the consensus opinion) a shared framework for their development, reporting and assessment 174. Ideally, each guideline consists of an algorithm or decision pathway outlining diagnostic, therapeutic and supportive care management, a manuscript discussing important issues related to the algorithm, and references providing data on which the recommendations are based 58. Furthermore, a good guideline should consider all relevant disciplines and stakeholders, as well as the local circumstances in which healthcare is delivered 175. It is however essential that these recommendations are continuously updated and revised to reflect new data and new clinical information. 2. To ensure that clinical guidelines improve patient care they should meet minimum quality criteria 176, 177. In the mid nineties a group of researchers from 13 countries developed the Appraisal of Guidelines Research and Evaluation (AGREE) Instrument. The objectives of the project were to provide a framework to create

KCE reports vol.45 Screening for Colorectal Cancer 49 a coordinated international approach to the appraisal of clinical guidelines and to identify potential areas for harmonization of guideline development178, 174. Health Care/Prevention Recommendations (HC/PR), on the other hand, are issued by regional, national or supranational (EU, WHO, ) governmental advisory committees involved with public health and chiefly address the public, politicians and the public health administrations of the respective countries. They focus on implementation of cancer screening programs within the frame of the general priority setting on the use of healthcare resources, screening coverage and compliance, quality assurance at all levels and good public information about benefits and risks 179. Although grounded on published scientific evidence, structured grading of the evidence generally is not their main concern. Table 11 gives an overview of the 20 retrieved guidelines and recommendations on CRC screening and surveillance. Some of them solely deal with average risk screening (mass screening), others include recommendations on increased risk screening and/or surveillance topics.
