Demand for endoscopies in the United Kingdom is increasing, contributing to mounting wait times and physical stresses on treatment environments that struggle to handle the growing volume of patients. When one endoscopy unit moved to redesign their facility to better accommodate higher capacities and generally enhance facility performance, researchers saw an opportunity to study the application of the Lean “3P” (short for production preparation process). This is a design method that engages cross-functional stakeholders in a new department’s design stages. The Lean 3P method works to provide a structured approach for clinical and corporate staff to collaborate with patient representatives, ensuring that several unique perspectives are incorporated into the design process. During this study, “point of delivery” (POD) principles were also emphasized, which focus on providing dignity and privacy to patients through informed design decisions.
