All guideline recommendations require a confidential vote by the writing committee and must be approved by a consensus of the vot- ing members. Members may not draft or vote on any text or recommendations pertaining to their RWI. Members who recused themselves from voting are indicated in the list of writing committee members, and specific section recusals are noted in Appendix 1. Authors and peer reviewers RWI pertinent to this guideline are disclosed in Appendixes 1 and 2, respectively. In addition, to ensure complete transparency, writing committee members comprehensive disclosure information including RWI not pertinent to this docu- ment is available as an online supplement. Comprehensive disclosure information for the Task Force is also available online at http://www.cardiosource.org/ACC/About-ACC/ Who-We-Are/Leadership/Guidelines-and-Documents-Task- Forces.aspx. The work of writing committees is supported exclusively by the ACCF and AHA without commercial sup- port. Writing committee members volunteered their time for this activity. In an effort to maintain relevance at the point of care for practicing physicians, the Task Force continues to oversee an ongoing process improvement initiative. As a result, in response to pilot projects, several changes to these guidelines will be apparent, including limited narrative text, a focus on summary and evidence tables (with references linked to abstracts in PubMed), and more liberal use of summary rec- ommendation tables (with references that support LOE) to serve as a quick reference. In April 2011, the Institute of Medicine released 2 reports: Finding What Works in Health Care: Standards for Systematic Reviews and Clinical Practice Guidelines We Can It is noteworthy that the IOM cited ACCF/AHA prac- tice guidelines as being compliant with many of the proposed standards. A thorough review of these reports and of our cur- rent methodology is under way, with further enhancements anticipated.
