P082: Current state of POCUS usage in canadian emergency departments

Abstract

Introduction: Point of care ultrasound (POCUS) has many applications in Emergency Medicine which are proven to improve patient outcomes. Training programs and guidelines for its use are available but its utilization metrics across Canadian Emergency Departments are unknown. This study aims to provide a comprehensive national assessment of POCUS usage, with a key component comparing training with patterns of use. Methods: A survey was distributed via email to all staff adult emergency physician members of the Canadian Association of Emergency Physicians (CAEP). The survey included questions related to training, attitudes towards POCUS, POCUS utilization, and barriers to POCUS use. Standard descriptive statistics were calculated, and differences in mean POCUS usage between groups were measured using a one-way analysis of variance (ANOVA). Results: The survey received 189 responses from emergency physicians from across Canada, 81% of which viewed POCUS as “useful and essential”. Respondents indicated that on average, POCUS was used during 71% (SD 29%) of shifts and on 23% (SD 17%) of patients. POCUS was most commonly used for basic applications, including thoracoabdominal trauma (FAST), cardiac assessment in arrest (trans-abdominal), and assessing for pericardial effusion. The most commonly cited barrier to wider POCUS adoption was a lack of training, with 41% of respondents identifying this as an issue. Correspondingly, formal POCUS training and certification were associated with significantly higher POCUS usage: usage rates ranged from 11.5% (SD 10.5%) of patients for those with formal training but no certification to 39.5% (SD 16.4%) of patients for those with a POCUS fellowship (p <0.001). Conclusion: The presented results from this survey provide an initial overview of the current state of POCUS usage in Canadian Emergency Departments. In summary, a higher level of training was associated with higher POCUS usage, and over a third of the respondents cited lack of training as a barrier to adoption; this suggests that efforts to facilitate POCUS utilization should focus on improving access to formal training and certification. Future work will involve further evaluation of additional barriers preventing POCUS usage in the ED, with the goal of providing information that will encourage changes that support widespread POCUS adoption.
