Developing a performance data suite to facilitate lean improvement in a chemotherapy day unit

A multidisciplinary team from the Peter MacCallum Cancer Centre in Melbourne, Australia, developed a performance data suite to support a service improvement project based on lean manufacturing principles in its 19-chair chemotherapy day unit (CDU) and cytosuite chemotherapy production facility. The aims of the project were to reduce patient wait time and improve equity of access to the CDU.

A project team consisting of a pharmacist and CDU nurse supported the management team for 10 months in engaging staff and customers to identify waste in processes, analyze root causes, eliminate non-value-adding steps, reduce variation, and level workloads to improve quality and flow. Process mapping, staff and patient tracking and opinion surveys, medical record audits, and interrogation of electronic treatment records were undertaken.

This project delivered a 38% reduction in median wait time on the day (from 32 to 20 minutes; P < .01), 7-day reduction in time to commencement of treatment for patients receiving combined chemoradiotherapy regimens (from 25 to 18 days; P < .01), and 22% reduction in wastage associated with expired drug and pharmacy rework (from 29% to 7%; P < .01). Improvements in efficiency enabled the cytosuite to increase the percentage of product manufactured within 10 minutes of appointment times by 29% (from 47% to 76%; P < .01).

A lean improvement methodology provided a robust framework for improved understanding and management of complex system constraints within a CDU, resulting in improved access to treatment and reduced waiting times on the day.
