Machine learning in clinical practice: Evaluation of an artificial intelligence tool after implementation.
Artificial intelligence (AI) has gradually found its way into healthcare, and its future integration into clinical practice is inevitable. In the present study, we evaluate the accuracy of a novel AI algorithm designed to predict admission based on a triage note after clinical implementation. This is the first of such studies to investigate real-time AI performance in the emergency setting. ⋯ Our study showed the diagnostic evaluation of a real-time AI clinical decision-support tool became less accurate than the original. Although real-time sensitivity and specificity of the AI tool was still acceptable as a decision-support tool in the ED, we propose that continuous training and evaluation of AI-enabled clinical support tools in healthcare are conducted to ensure consistent accuracy and performance to prevent inadvertent consequences.

Contemporary management of acute heart failure in the emergency department and the potential impact of early diuretic therapy on outcomes.
Acute heart failure (AHF) is one of the most common conditions presenting to the ED and patients often require hospitalisation. Emerging evidence suggests early diagnosis and administration of diuretics are associated with improved patient outcomes. Currently, there is limited literature on the management of AHF in the Australian ED context. ⋯ Despite symptoms and signs being well recognised at presentation, time to diuretics was relatively long. Early diuretics administration was associated with improved patient outcomes, particularly in clinically more stable patients. Due to the limitations of the study design, results should be interpreted with caution and warrant further research to identify factors that delay timely administration of diuretics.

What is the prevalence of orthostatic hypotension in an Australasian emergency department population?
Orthostatic hypotension (OH) is associated with increased morbidity and there is limited research on the prevalence in the Australian ED population. The aim was to determine the prevalence of OH in an Australian ED population. Secondary outcomes included any associations of OH with symptoms, presenting complaints, patient demographics, or hospital admission, and the timing of OH findings. ⋯ In this single Australian ED population, there was a high prevalence of OH (22.1%) with most cases detected within 3 min of standing. A higher-powered study across multiple sites would better substantiate these findings.
