Lean transformation framework for treatment-oriented outpatient departments

Long wait times and low resource utilisation are the most critical issues in treatment-oriented outpatient departments. While Lean has been utilised to resolve similar issues in healthcare, the literature provides no structured means of implementing Lean in outpatient departments. This study establishes a Lean transformation framework to identify a balanced patient demand by determining proper patient compositions, to schedule non-specialists to increase resource utilisation, and to level patient schedule throughout the day to reduce wait times. This framework includes a series of activities and Lean tools that are specifically adapted for use in outpatient departments. A case study is presented to illustrate the implementation of the proposed framework and its possible impacts, using data from a community hospital oncology department in Montreal, Canada. Results suggests that this framework reduces patient visit time by 36% and increases daily treatments by 39% and utilisation of chemotherapy chairs by 22%, with a possibility to implement a one-day treatment regime. The proposed framework can assist treatment-oriented outpatient departments to overcome their operational challenges and to serve as an effective guideline in their Lean transformation.

Automated summary

The Lean transformation framework established in this study aims to reduce wait times and increase resource utilisation in treatment-oriented outpatient departments by identifying balanced patient demand, scheduling non-specialists, and levelling patient schedules. Results from a case study show significant improvements in patient visit times, daily treatments, and utilisation of resources, indicating the framework's effectiveness in Lean transformation.
