I could not agree more.
The authors emphasize the importance of designing models and processes that result in quality and efficiency of care. Technology is mentioned as a means to augment standardization.
All of that is spot on, however, one explicit point was conspicuously absent from the paper: In the absence of hospital executive sponsorship and commitment to standardization, optionalism will reign. Forget your focus groups, your root cause analyses, your quality improvement models etc, without executive oversight-vision, resources, mandates and accountability, this all adds up to nil.
Trust the process.
