4. 4 2007 Canadian Hypertension Education Program Recommendations Canada has had annually updated evidence-based recommendations since 1999. The CHEP process was initiated in 2000 as part of a national strategy to improve blood pressure control in Canada. The 2000 process was linked to the periodic update of lifestyle and hypertension management recommendations in 1999. The production of recommendations are linked a separate and specific implementation plan and to an evaluation strategy. Canadian Recommendations for the Management of Hypertension

9. 9 2007 Canadian Hypertension Education Program Recommendations CHEP - MINIMIZING BIAS CHEP recognizes bias as a serious threat to recommendations processes and takes multiple steps to reduce its impact. Overt steps taken to reduce bias include. 1) A history of requiring a high level of evidence with patient outcomes for pharmacotherapy recommendations 2) A centralized systematic literature review 3) Multiple members in subgroups to represent different views

10. 10 2007 Canadian Hypertension Education Program Recommendations CHEP- MINIMIZING BIAS 4) A Central Review Committee (CRC) that is ‘free of COI’ to oversee the evaluation of evidence, development of recommendations and to present the evidence/ recommendations 5) Overt written disclosure of potential COI at the time of the development of the recommendations 6) A consensus approach to the drafting of the recommendations chaired by the CRC 7) Voting on recommendations with the removal of recommendations voted against by 30% of members.

11. 11 2007 Canadian Hypertension Education Program Recommendations CHEP- MINIMIZING BIAS 8)Themes, key messages and major implementation tools are developed through a consensus of the full executive. Other internal implementation tools require the consensus of two members of the executive. 9)External implementation tools must be completely consistent with the content and intent of CHEP recommendations and require a consensus of 3 members of the executive. The CHEP executive prioritized minimizing the potential impact of bias at it’s business planning retreat in May 2006.
