Abstract
At LDS Hospital the authors are implementing continuous quality improvement (CQI), a systems-analytic approach to quality management in industry, as an approach to quality management in medical domains. Their approach consists of 1) choosing a process to be improved, 2) assembling a team of expert clinicians that understands the process and the outcomes, 3) determining key steps in the process and expected outcomes, 4) collecting data that measure the key process steps and outcomes, and 5) feeding back the data to the practitioners. CQI theory states that the practitioners will use the information and their own best intentions to improve the manner in which they provide care. The authors have developed statistical tools that display the data and distinguish between random and assignable variation.
