Objectives Point‐of‐care ultrasound (POCUS) is a widely used diagnostic modality in the emergency physician's tool kit. The effect on health care costs is disputed. This study examined whether POCUS was associated with system‐level cost savings. Secondary objectives included adverse patient outcomes and the association between POCUS use and diagnostic costs in specific patient groups. Methods The Point‐of‐Care Ultrasound Use and Monetary Outcomes study was a single‐center prospective observational study. A convenience sample of emergency medicine physicians working from July to October 2019 were included after using POCUS as part of their assessment. The cost of patient investigations was compared with those proposed by a control group of physicians simultaneously on shift, who were blinded to the POCUS findings. Ethical approval was obtained from the Queen's University Health Sciences Research Ethics Board. Results Fifty patient assessments using POCUS were included. Overall, the median investigation cost in United States dollars in the POCUS group was $102.00 (interquartile range [IQR], $39.80–$167.90) versus $122.40 (IQR, $70.96–$175.60) in controls ( P = .08). When stratified by disposition, POCUS use in patients discharged home resulted in a median expenditure of $71.80 (IQR, $36.48–$116.70) versus $122.70 (IQR, $71.18–$183.20; P < .001). Significant cost savings were also found in flank pain presentations (median, $138.90; IQR, $136.60–$186.10; P = .01). There were no differences in the quantity of investigations ordered, the patient emergency department repeated presentation rate, or safety outcomes at 7 days. Conclusions Point‐of‐care ultrasound use was not associated with significant cost savings in our overall population. The subgroup analysis revealed significant POCUS‐associated cost savings in patients discharged home and those presenting with flank pain. Notably, POCUS was not associated with an increase in adverse patient safety outcomes.
