Is evidence of effectiveness a driver for clinical decision support selection? A qualitative descriptive study of senior hospital staff.

: Decisions to implement CDS, and technology more broadly, are rarely evidence-based. In the absence of evidence, evaluation or monitoring of technologies post-implementation is critical, particularly to identify new errors or risks associated with HIT implementation and use. Increased transparency from vendors, with technology evaluation outcomes made directly available to healthcare organizations, may result in less reliance on logic, intuition, and vendor assertions, and more evidence-based selection of HIT.
