Article Synopsis
- The study aimed to determine how the timing of initial antibiotic treatment affects mortality rates in hospital patients with sepsis.
- It analyzed data from 42 studies involving nearly 191,000 patients, focusing on the correlation between antibiotic administration timing and patient outcomes.
- Results indicated that administering antibiotics within 3-6 hours of sepsis recognition significantly reduced the risk of death compared to later administration, highlighting the urgency of early treatment.
Background: We aim to compare the prognostic value of Quick Sepsis-Related Organ Failure Assessment (qSOFA) and the previous Systemic Inflammatory Response Syndrome (SIRS) criteria, the National Early Warning Score (NEWS) and along with their combinations in the emergency department (ED).
Methods: This single-centre prospective study recruited a convenience sample of unselected ED patients triaged as category 2 (Emergency) and 3 (Urgent). Receiver Operating Characteristic analyses were performed to determine the Area Under the Curve (AUC), along with sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios for the various scores.
Background: Glasgow Coma Scale (GCS) is one of the most commonly used patient assessment tools. This study aimed to determine whether an assessment aid can improve the GCS scoring accuracy by helicopter rescuers in Hong Kong.
Methods: In this randomised controlled trial, Air Crewman Officers (ACMOs) of Government Flying Service in Hong Kong were randomised into two groups, with and without assessment aid.
Article Synopsis
- Capillary blood lactate testing with handheld devices can expedite clinical decisions, particularly in prehospital settings.
- A study was conducted in a Hong Kong emergency department, involving 240 urgent care patients to assess the agreement between capillary lactate levels from handheld analysers and venous levels from a blood gas analyser.
- Results indicated poor agreement between the capillary measurements and the reference standard, suggesting limited clinical usefulness of the handheld lactate devices.
Background: To determine the validity of the Quick Sepsis-Related Organ Failure Assessment (qSOFA) in the prediction of outcome (in-hospital and 1-month mortality, intensive care unit (ICU) admission, and hospital and ICU length of stay) in adult patients with or without suspected infections where qSOFA was calculated and reported; Methods: Cochrane Central of Controlled trials, EMBASE, BIOSIS, OVID MEDLINE, OVID Nursing Database, and the Joanna Briggs Institute EBP Database were the main databases searched. All studies published until 12 April 2018 were considered. All studies except case series, case reports, and conference abstracts were considered.

Methods: The study was a prospective, paired-control design (pre-training control group & post-training group), utilizing Emergency Medical Assistant (EMA) I and II trainees from the Hong Kong Fire Services Ambulance Command Training School. A nomogram (blood loss volume to area on a non-absorbent surface) was prepared to aid blood loss estimation.
