EGS SO05 - Improving the Flow of Patients Attending Surgical Assessment Unit: Introduction of Ambulatory USS Slots - Closed Loop Audit

Abstract Background Modern emergency surgical service recognises that a significant proportion of patients presenting with acute abdomen can be diagnosed and treated in the ambulatory fashion. However, this approach requires multidisciplinary cooperation between the general surgery team and radiology department. We aimed to assess and improve the flow of patients presenting to Surgical Assessment Unit (SAU) with complaints of right iliac fossa (RIF) and right upper quadrant (RUQ) pain. Method We performed a retrospective analysis of all ambulatory patients returning to SAU of a District General Hospital with RUQ and RIF pain in January 2023. We measured the waiting time between the arrival to SAU and the time of USS. We presented the results in a local meeting and negotiated the introduction of two daily USS slots for SAU patients. We re-assessed the impact of the USS slots on waiting times in July 2023. Results In January 2023, 13 patients returned to SAU for USS. The minimum waiting time for this cohort was 59 minutes and the maximum waiting time was 3 hours and 39 minutes. The median was 2 hours and 15 minutes. In July 2023, 18 patients returned to SAU for USS. The minimum waiting time for this cohort was 4 minutes and the maximum waiting time was 2 hours and 20 minutes. The median was 1 hour and 5 minutes. There was an average reduction of 1 hour and 10 minutes in waiting time for USS. Conclusion The introduction of two USS slots per day for patients returning to SAU with RUQ and RIF pain resulted in a 48% reduction in waiting times. This improved the flow of patients, sped up the diagnosis and timely access to treatment, as well as significantly improved patients experience and satisfaction. We would recommend close co-operation between general surgery and radiology to allow timely access to imaging for patients presenting with acute abdomen to SAU.
