Prognostic accuracy of qSOFA score, SIRS criteria, and EWSs for in-hospital mortality among adult patients presenting with suspected infection to the emergency department (PASSEM) Multicenter prospective external validation cohort study protocol.

BACKGROUND: Early identification of a patient with infection who may develop sepsis is of utmost importance. Unfortunately, this remains elusive because no single clinical measure or test can reflect complex pathophysiological changes in patients with sepsis. However, multiple clinical and laboratory parameters indicate impending sepsis and organ dysfunction. Screening tools using these parameters can help identify the condition, such as SIRS, quick SOFA (qSOFA), National Early Warning Score (NEWS), or Modified Early Warning Score (MEWS). We aim to externally validate qSOFA, SIRS, and NEWS/NEWS2/MEWS for in-hospital mortality among adult patients with suspected infection who presenting to the emergency department. METHODS AND ANALYSIS: PASSEM study is an international prospective external validation cohort study. For 9 months, each participating center will recruit consecutive adult patients who visited the emergency departments with suspected infection and are planned for hospitalization. We will collect patients' demographics, vital signs measured in the triage, initial white blood cell count, and variables required to calculate Charlson Comorbidities Index; and follow patients for 90 days since their inclusion in the study. The primary outcome will be 30-days in-hospital mortality. The secondary outcome will be intensive care unit (ICU) admission, prolonged stay in the ICU (i.e., ≥72 hours), and 30- as well as 90-days all-cause mortality. The study started in December 2021 and planned to enroll 2851 patients to reach 200 in-hospital death. The sample size is adaptive and will be adjusted based on prespecified consecutive interim analyses. DISCUSSION: PASSEM study will be the first international multicenter prospective cohort study that designated to externally validate qSOFA score, SIRS criteria, and EWSs for in-hospital mortality among adult patients with suspected infection presenting to the ED in the Middle East region. STUDY REGISTRATION: The study is registered at ClinicalTrials.gov (NCT05172479).

Emergency department management of patients with ACE-inhibitor angioedema.

BACKGROUND: Angiotensin-converting-enzyme inhibitors (ACEI) are one of the most prescribed medications worldwide. Angioedema is a well-recognized adverse effect of this class of medications, with a reported incidence of ACEI angioedema of up to 1.0%. Of importance to note, ACEI angioedema is a class effect and is not dose dependent. The primary goal of this literature search was to determine the appropriate Emergency Department management of patients with ACEI angioedema. METHODS: A MEDLINE literature search from January 1990 to August 2012 and limited to human studies written in English for articles with keywords of ACEI angioedema. Guideline statements and non-systematic reviews were excluded. Studies identified then underwent a structured review from which results could be evaluated. RESULTS: Five hundred sixty-two papers on ACEI angioedema were screened and 27 appropriate articles were rigorously reviewed in detail and recommendations given. CONCLUSION: The literature search did not support any specific treatment protocol with a high level of evidence due to the limited--and limitations of the--available studies.

Is culture-positive urinary tract infection in febrile children accurately identified by urine dipstick or microanalysis?

BACKGROUND: Fever from a urinary tract source remains the predominant etiology of serious bacterial infection in children ages 0-36 months. Urine culture is the gold standard for diagnosing a urinary tract infection (UTI); however, urine dipstick (UDip) and urine microanalysis (UA) are typically used real time by Emergency Physicians to diagnose and treat UTIs, as cultures can take days to grow and be available. The purpose of this article is to evaluate the literature on the accuracy and utility of the UDip and UA in this pediatric population. METHODS: A structured review of the medical literature to determine the accuracy of UDip and UA for the diagnosis of UTI in children before the result of the urine culture. RESULTS: Upon comprehensive review and after applying predefined inclusion criteria, a total of 13 articles met inclusion criteria, addressed the clinical question, and were reviewed in detail. CONCLUSIONS: The literature search did not conclusively identify any component of either the UDip or the UA, which would allow a practitioner to conclude definitively that the source of an infant's fever is a UTI.
