Towards quality assurance: implementation of a POCUS image archiving system in a high-volume community emergency...

Quality assurance review is an integral part of point-of-care ultrasound (POCUS) programs but may not be routine practice in community hospitals. Lack of image acquisition and documentation can result in suboptimal patient care. In cases with an adverse outcome and no record of images, there is no mechanism for quality improvement.

Our goal was to implement a system of POCUS image archiving in a community hospital. Our SMART (Specific, Measurable, Actionable, Realistic, Timely) aim was to have > 50% of emergency department (ED) POCUS users archiving scans, and > 80% of all billed POCUS scans archived, measuring improvements bi-weekly over a period of 9 months.

The study was conducted at a single-community ED between August 2020 and April 2021. The POCUS archiving workflow was developed and refined through multiple plan-do-study-act (PDSA) cycles. Surveys, stakeholder meetings, audits, and feedback were used to generate and re-evaluate the interventions. These included introduction of QPathE© software, streamlining of the workflow process, strategic machine placement, POCUS rounds, use of a website for POCUS workflow instructions, and dissemination of audit results. Scans were tracked biweekly, and indexed by the number of scans billed. The primary outcome measure was the number of POCUS scans archived per 100 scans billed.

Over a 9-month period, spanning 72,986 ED visits, 550 scans were archived. The percentage of POCUS users who changed practice to consistently archiving scans was 51%. The rate of POCUS scans archived per 100 scans billed was > 80%, compared to no archiving at baseline.

We were able to transition from a system with entirely unarchived POCUS scanning, to one with > 80% of scans archived over a period of 9 months. This is the first published paper documenting implementation of a POCUS image archiving system in a Canadian Community ED.
