Getting it ‘Right’: Pulmonary Hypertension in the ED

ObjectivesDescribe the pathophysiology of Pulmonary Hypertension (PH), and how it can be dangerousWho to suspect and workup for PH in the EDDescribe the POCUS findings in PHDescribe the management of these patients and how to avoid causing harm PhysiologyDefinition Pulmonary hypertension (PH) is defined as a pulmonary artery mean pressure >25 mmHg by right heart catheterization at rest. Transthoracic echocardiography is used as a screening tool with a right ventricular systolic pressure (RVSP) > 40 being suggestive but not diagnostic of PH (1,2).
Classification PH can be divided broadly into conditions primarily affecting pulmonary arterioles (Group 1) or secondary causes that progressively lead to changes in the pulmonary arteries (Groups 2-5). 
Group 1 is pulmonary arterial hypertension that is:  idiopathicheritabledrug-induceassociated with other conditions (eg. HIV, schistosomiasis, portal hypertension) The secondary causes include:  Group 2: Left sided heart disease (eg. valvu…

The ABCDE’s of Quality Improvement

What is Quality Improvement (QI)? You have all heard the latest buzzword in healthcare: “quality improvement”, or QI. Yet many healthcare professionals still only have a vague idea of what that truly means, and likely an even poorer understanding of how it might apply to their frontline practice. Conceptually, QI can be defined as the “combined and unceasing efforts of everyone - healthcare professionals, patients and their families, researchers, payers, planners and educators - to make the changes that will lead to better patient outcomes (health), better system performance (care) and better professional development (learning)”1. 

Comparison of risk scoring systems for patients presenting with upper gastrointestinal bleeding: international multicentre prospective study.

Journal Club Summary Methodology Score:4/5 Usefulness Score:4/5 Stanley AJ, et al. BMJ. 2017 Jan 4;356:i6432. Full Article This multicentre, multinational study assessed the ability of five upper gastrointestinal bleeding scores to predict outcomes including death, re-bleeding, need for endoscopy, transfusion, surgery or interventional radiology, and length of hospital stay, finding that the Glasgow Blatchford score is best at predicting the composite outcome of intervention or death, although AIMS65 was best at predicting mortality. While applying the scores as recommended may result in missing a small number of significant outcomes, they are easy to apply and can help expedite disposition planning, whether outpatient management or hospital-based intervention.

Zika Virus – What we know and what we don’t

The Zika Virus exploded onto the international health scene in the last several months. It was first discovered in humans in 1951 and remained limited to Africa and Asia until the first major outbreak in Micronesia in 2007. Since then the virus has continued to evolve and spread from the Pacific Islands and French Polynesia to the main major outbreak in South America in early 2015 and finally to the US in January 2016.
