Implementation of Lean healthcare methodology in designing an Intravitreal Injection Center: first Italian experience

The principles of the Lean methodology, introduced by Toyota to improve productivity, are relevant to other settings, including healthcare. We aimed to use Lean methodology to design a new setting in our ophthalmology clinic to improve the management of patients receiving an intravitreal injection for ocular diseases.

The location of services, days of operation, scheduling and processing of patients, utilization of staff, data recording methods, and examination and surgical procedures were analyzed, and a new Intravitreal Injection Center was developed according to Lean principles.

The new setting, which is confined to a single floor, in contrast to the previous system, which necessitated that patients visit various locations spread over three floors of the hospital, demonstrated benefits for patients and improved the flow and management of patients through the system with a need for fewer team members. The intravitreal injection service improved with regard to both the quality and speed of the overall procedure and the efficient use of staff.

Our aim to achieve a fast and one-way route to move patients through intravitreal injection administration was achieved, limiting any waste of time and space and improving the capacity management of the center. The system is of relevance to other ophthalmology clinic settings and facilitates the collection of valuable epidemiological and clinical information on the response of patients to different drugs and treatment regimens.
