Review Meta Analysis
Diagnostic accuracy of lung ultrasound performed by novice versus advanced sonographers for pneumonia in children: A systematic review and meta-analysis.
Childhood pneumonia is a leading cause of mortality worldwide. Growing evidence suggests that lung ultrasound (LUS) may be a reliable diagnostic alternative to chest x-ray for childhood pneumonia. However, it is unclear whether sonographer experience affects the diagnostic accuracy of LUS. We summarize the diagnostic accuracy of LUS for pneumonia and compare the performance between novice and advanced sonographers with a systematic review and meta-analysis. ⋯ LUS can accurately diagnose pneumonia in children. However, this test demonstrates operator-dependent variability, with more experienced sonographers having higher diagnostic accuracy. Further work on evidence-based educational methods to train novice sonographers in LUS is required.

Review Meta Analysis
Point-of-Care Ocular Ultrasound for the Diagnosis of Retinal Detachment: A Systematic Review and Meta-Analysis.
Ocular complaints are common presentations to the emergency department (ED). Among these, retinal detachment can cause significant vision loss if not rapidly diagnosed and referred for appropriate treatment. Point-of-care ultrasound has been suggested to identify the diagnosis rapidly when the ocular examination is limited or the ophthalmology service is not readily available. However, prior studies were limited by small sample sizes, resulting in wide ranges of potential accuracy. The primary outcome for this review was to determine the test characteristics of point-of-care ocular ultrasound for the diagnosis of retinal detachment. ⋯ Point-of-care ocular ultrasound is sensitive and specific for the diagnosis of retinal detachment. Future studies should determine the ideal training protocol and the influence of color Doppler and contrast-enhanced ultrasound on diagnostic accuracy.

Ketamine has been studied as an alternative to opioids for acute pain in the emergency department setting. This review compares the effectives of intravenous ketamine at a dose of <0.5mg/kg to opioids for acute pain in adult patients. ⋯ Ketamine was found to have similar effectiveness to opioids. Increased, but short-lived, side effects were seen with ketamine.

Review Meta Analysis
Prognostic Accuracy of the HEART Score for Prediction of Major Adverse Cardiac Events in Patients Presenting with Chest Pain - A Systematic Review and Meta-Analysis.
The HEART score has been proposed for emergency department (ED) prediction of major adverse cardiac events (MACE). We sought to summarize all studies assessing the prognostic accuracy of the HEART score for prediction of MACE in adult ED patients presenting with chest pain. ⋯ The HEART score has excellent performance for prediction of MACE (particularly mortality and MI) in chest pain patients and should be the primary clinical decision instrument used for the risk stratification of this patient population.

Meta Analysis
Accuracy of Dementia Screening Instruments in Emergency Medicine - A Diagnostic Meta-Analysis.
Dementia is underrecognized in older adult emergency department (ED) patients, which threatens operational efficiency, diagnostic accuracy, and patient satisfaction. The Society for Academic Emergency Medicine geriatric ED guidelines advocate dementia screening using validated instruments. ⋯ ED-based diagnostic research for dementia screening is limited to a few studies using an inadequate criterion standard with variable masking of interpreter's access to the index test and the criterion standard. Standardizing the geriatric ED cognitive assessment methods, measures, and nomenclature is necessary to reduce uncertainties about diagnostic accuracy, reliability, and relevance in this acute care setting. The AMT-4 is currently the most accurate ED screening instrument to increase the probability of dementia and the Brief Alzheimer's Screen is the most accurate to decrease the probability of dementia. Dementia screening as one marker of vulnerability to initiate comprehensive geriatric assessment is warranted based on test-treatment threshold calculations.
