Steering Committee

The AHRQ Patient-Centered Outcomes Research (PCOR) Clinical Decision Support (CDS) Learning Network (LN) Steering Committee (SC) plays a leading and supervising role on the project. The PCOR CDS-LN SC shall provide oversight to the PCOR CDS-LN project in its entirety with the primary purpose being to engage stakeholders to identify and foster opportunities to disseminate and incorporate PCOR findings into CDS to drive appropriate care and improve health outcomes. The PCOR CDS-LN SC will serve as the final deciding entity for issues that project teams cannot resolve without escalating to a higher level and therefore require adjudicating. The SC will monitor and review the project’s status, as well as provide timely guidance for overcoming potential barriers. 

The PCOR CDS-LN SC is responsible for providing direction, vision, and insight on long-term strategies to ensure the PCOR CDS-LN works toward the purpose outlined above and aligns with identified PCOR CDS scientific and stakeholder needs. Members of the SC ensure business objectives are being adequately addressed and the project remains on target. In practice, these responsibilities are carried out by performing the following functions: 

  • Providing guidance to support the completion of key deliverables 
  • Monitoring the project status at regular monthly SC meetings 
  • Voting and making final decisions 
  • Resolving project conflicts and disputes, reconciling differences of opinion and approach
