Improving patient access to an interventional US clinic.

A continuous quality improvement project was conducted to increase patient access to a neurointerventional ultrasonography (US) clinic. The clinic was experiencing major scheduling delays because of an increasing patient volume. A multidisciplinary team was formed that included schedulers, medical assistants, nurses, technologists, and physicians. The team created an Ishikawa diagram of the possible causes of the long wait time to the next available appointment and developed a flowchart of the steps involved in scheduling and completing a diagnostic US examination and biopsy. The team then implemented a staged intervention that included adjustments to staffing and room use (stage 1); new procedures for scheduling same-day add-on appointments (stage 2); and a lead technician rotation to optimize patient flow, staffing, and workflow (stage 3). Six months after initiation of the intervention, the mean time to the next available appointment had decreased from 25 days at baseline to 1 day, and the number of available daily appointments had increased from 38 to 55. These improvements resulted from a coordinated provider effort and had a net present value of more than $275,000. This project demonstrates that structural changes in staffing, workflow, and room use can substantially reduce scheduling delays for critical imaging procedures.
