M ultidisciplinary rounding formats are common in pediatric cardiac intensive care settings. Most pediatric cardiac ICUs (CICUs) house a preponderance of surgical patients who are usually comanaged with cardiothoracic surgery. At many large centers, there is daily communication between teams in the setting of multidisciplinary surgical rounds. This process is rife with challenges in balancing the efficiency-thoroughness tradeoff. Brown et al (1) sought to improve the efficiency of the process of surgical rounds in response to feedback from their teams. The use of Lean methodology in the specific context of pediatric cardiac critical care multidisciplinary surgical rounds is novel. They describe how the principles of Lean process improvement can be applied to integral, complex, cognitively challenging processes in the healthcare setting as part of the process for improvement.Lean Manufacturing was developed by the Toyota Motor Corporation as a methodology to assess real world working conditions in manufacturing and eliminate waste. The seven types of waste or "muda" identified by lean are: transportation (moving materials), inventory (storage of parts prior to production), motion (unnecessary movement of people), waiting (idle time for equipment), overprocessing (processing beyond customer demands), over production (producing inventory far in excess of demand), and defects (creation of defective products) (2). When applied to healthcare, workflows and care delivery processes are often the product. In its applications in healthcare as in manufacturing, we must ask some key questions before embarking on the lean journey. Who is the customer? What is the product? Embarking on the Lean improvement method can help identify what can be more efficient, and what is wasteful. Previous reports applications of lean in healthcare delivery have included intensive care team rounds at a tertiary care center, where the authors found improved timeliness and efficiency of patient-centered rounds as well as improved team and customer satisfaction with the process (3, 4). Lean methods have been used in a range of other healthcare settings: from primary care for improving efficiency of clinical tasks (5) to improve the rounding efficiency of surgical residents (6).The first stage of any project seeking to use lean methodology for quality improvement is to initiate a "Kaizen" ("change for better" in Japanese) event. In a "kaizen, " or rapid improvement process, event a team is formed that ideally operates with minimal logistical barriers to apply lean methodology. The five steps of lean process implementation are: specify value, identify the value *See also p. e282.
