Development and Usability Testing of CDS Alternatives January 8 th , 2008 Jason J. Saleem, PhD & Laura Militello, MA LEADERS SYMPOSIUM “ Strategic Planning to Inform a Funded Project on how to Achieve Workflow Integration in Developing and Implementing CDS for CRC Screening”
Specific Aim 1: Identify key approaches to CDS development for colorectal cancer screening at two VAMC sites and two nationally recognized non-VA sites, for effective CDS integration into clinical workflow.
Specific Aim 2: Develop and test CDS design alternatives for improved integration into clinical workflow through a controlled simulation study and subsequent implementation.
Key Informant Interviews of site-specific best-practices for integration of colorectal cancer screening CDS into workflow Direct Observation of colorectal cancer screening CDS for barriers and facilitators to workflow integration Implementation in primary care clinic after simulation study Rapid Prototyping of CDS design alternatives based on Phase 1 findings Simulation Study to test impact of CDS design alternatives on efficiency, usability, and workload Evaluation in primary care clinic after simulation study Figure.

Improved colorectal cancer screening CDS full development and implementation in live clinic for pilot test evaluation (Phase 3)
Phase 1 (naturalistic observation and key informant interviews) and Phase 2 (rapid prototyping and simulation study) methods based on successful previous work (Saleem et al., JAMIA, 2005; Saleem et al., JAMIA, 2007).
But fell short of direct impact to current VA system
