Emergency Department Patient

This study aims to evaluate a pre-post intervention adding an early management decision at the end of the triage process to improve patient throughput. The intervention consists of adding digital checkboxes to the electronic triage system, providing nurses with formalized options for anticipated management based on patient acuity. The study compares a pre-intervention phase (May 1st to July 31st, 2026) with a post-intervention phase (May 1st to July 31st, 2027) to naturalize seasonal confounders. The primary outcome is the total Emergency Department Length of Stay (ED LOS).

Introduction: The aging of the population is a global phenomenon, with projections indicating a significant increase in the proportion of individuals aged 60 years and older by 2050. This demographic shift requires adapting emergency department (ED) services to meet the specific demands of older patients, who often present with multiple comorbidities and face challenges such as sensory and cognitive difficulties. EDs, traditionally designed for acute illness and injury management, may not be adequately equipped to meet the unique needs of this vulnerable population. This can result in suboptimal patient experiences, prolonged ED stays, increased hospitalizations, and poorer outcomes. Methods: This study protocol outlines a before-and-after study to evaluate the impact of implementing a comfort menu and cart on the experience and outcomes of older patients treated in the ED. The study will be conducted in the ED of Hospital Sírio-Libanês (HSL), a tertiary private hospital in São Paulo, Brazil. Patients aged 60 and older who presented to the ED will be eligible for inclusion. Participants will be recruited in two phases: pre-intervention and post-implementation of the comfort menu and cart. Data will be collected through patient and staff interviews, chart reviews, and a 30-day follow-up interview. Patient experience, staff experience, length of hospital stays, hospital costs, ED readmissions, falls, delirium incidence, quality of life, functional status, cognitive performance, and mortality will be assessed. Ethics and dissemination: Ethical approval for this study has been granted by the Institutional Review Board of HSL. All participants, or their legal representatives for those with cognitive impairment, will provide written informed consent before any study procedures are initiated. The consent process has been designed keeping the study hypothesis blind by not revealing the outcomes that will be measured after the comfort cart intervention. The results will be shared with the academic community through peer-reviewed publications and presentations at relevant conferences to inform future clinical practice and research. Expected Results: A positive impact of implementing the comfort menu and cart in the ED is expected on patient-centered outcomes. Improvements in the experience of older patients and medical and multidisciplinary staff are anticipated, and improvements in other exploratory outcomes, such as length of hospital stay, hospital costs, readmissions, falls, delirium incidence, quality of life, functionality, and cognitive performance, will be explored.

The aim of this study is to assess emergency medicine physician and advanced practice provider (APP) knowledge and technical skill in performance of a point-of-care ultrasound simulation and just-in-time training pathway to determine the feasibility, acceptability, and usability of the ultrasound training program. By performing this study, we hope to create a standardized training model which could potentially facilitate point-of-care ultrasound (POCUS) clinical performance and thereby improve patient care.

The aim of this study is to assess the impact of hospitalisation outside the referral requested by the emergency doctor on the mortality of patients admitted to emergency departments.

Many patients in the emergency department have veins that are difficult to get an intrevenous (IV) catheter into (called "difficult IV access"). These patients may require other methods to obtain access to a vein for administration of the necessary medications. The 2-inch long IV is most commonly used in emergency departments for people with difficulty IV access. Typically, a healthcare worker will use an ultrasound to help to see the veins underneath the skin while inserting the IV into the vein. That is, the ultrasound helps the healthcare worker visualize veins that are deeper in the arm and may not be felt through the skin. Another device that can be used is a 4-inch midline catheter. This device is less commonly used as many emergency departments do not have participants available, but it serves the same purpose as the 2-inch long IVs (that is, to give medicine into the vein and sometimes to take blood). A 4-inch midline catheter is similar to a 2-inch long IV, but has a few differences. First, the 4-inch midline catheter is even longer than the 2-inch long IV. The 4-inch midline catheter is 10-cm (about 4-inches or the size of 4 quarters side-by-side), while the 2-inch long IV is 4.78-cm (nearly 2-inches or two quarters side-by-side). Second, the 4-inch midline catheter is inserted into using a guidewire to help move the catheter in the vein (similar in concept to a train moving along a track), while the 2-inch long IV does not have this guidewire. The guidewire does not hurt and most do not know it is being used. It is just an additional step to help guide the catheter in the vein. The investigators are conducting this research study to determine which catheter is better for patients with difficult IV access: the 4-inch midline catheter or the 2-inch long IV.

Acute low back pain is a frequent cause of emergency department admissions (4.39% \[95% CI: 3.67-5.18\])1. Drug therapeutic options are limited and ineffective. Paracetamol and opioids are no better than placebo for acute low-back pain 2,3. Only NSAIDs and muscle relaxants have a slightly beneficial effect on pain, but muscle relaxants have an unfavorable risk-benefit balance.2 In this situation, it is necessary to turn to new non-drug therapeutic options to relieve pain of these patients. Transcutaneous electrical nerve stimulation (TENS) is a non-drug therapy that involves applying an electrical current through the skin. Through one or two pairs of electrodes stuck to the skin, TENS delivers painless, low-intensity electrical impulses to a painful area or a nerve pathway. TENS acts by selectively activating large-diameter non-nociceptive afferent fibers to induce segmental analgesia4. In addition, TENS increases the concentration of endorphins in the bloodstream and cerebrospinal fluid5. The use of TENS has been studied mainly in chronic low-back pain. A 2007 Cochrane systematic review concluded that TENS appears to reduce pain and improve range of motion for subjects with chronic low back pain6. The use of TENS in emergency departments has been little studied. A 2018 pilot study of 110 patients admitted to the emergency department with acute or chronic pain observed a reduction in pain (from an average of 8.50 on the numerical pain scale \[EN\] \[7.52 - 9.48\] to 4.67 \[3.51 - 5.89\]) after TENS use and functional improvement in 83% of patients7. The Gulacti study, carried out in 2022, investigated the use of TENS to treat pain of patients admitted to the emergency department with a renal colic attack : the mean reduction in VAS score at 15 and 30 minutes was significantly greater for the TENS group than for the placebo group (mean reduction in VAS score at 15 minutes was 33.3 ± 17.6 (95% CI : 28.3 to 38.3) for the TENS group and 14.9 ± 11.6 (95% CI: 11.6 to 18.2) for the placebo group \[mean difference: 18.4 (95% CI: 12.5 to 24.4, P \< 0.0001)\]. The mean reduction in VAS score after 30 minutes was 63.7 ± 21.1 (95% CI: 57.7 to 69.7) for the TENS group and 14.9 ± 16.2 (95% CI: 19.5 to 10.3) for the placebo group (mean difference: 48.8, 95% CI: 41.4 to 56.3, P \< 0.0001)8. A single study of 76 patients focused on acute low-back pain during patient transport to emergency departments. The authors recorded a significant reduction (p= 0.01) in pain during transport of the TENS group (79.2 ± 6.5 mm VAS to 48.9 ± 8.2 0 mm VAS), while pain scores remained unchanged for the placebo group (75.9 ± 16.4 mm VAS and 77.1 ± 11.2 mm VAS)9. To our knowledge, there is no high-quality study of TENS versus placebo for acute low back pain of patients admitted to an emergency department. 1. Primary objective: Study the analgesic efficacy of TENS compared to placebo in the treatment of acute low back pain at the emergency department. 2. Secondary objective: 1\. Compare the number of patients who will show a \> 50% reduction of their initial pain. 2\. Compare the number of patients requiring rescue treatment. 3. Compare the occurrence of side effects among groups. 4. Compare patient satisfaction after 30 minutes. 5. Compare patient comfort level after 30 minutes. Main criterion: Comparison of the proportion of patients with \>30% reduction of initial pain after 30 minutes of treatment Secondary criterion: 1. Proportion of patients with \> 50% reduction of their initial pain after 30 minutes of treatment. 2. Proportion of patients requiring morphine titration for pain relief. 3. The rate of side-effects associated with the use of TENS. 4. The level of satisfaction measured by numerical satisfaction scale ranging from 0 (not at all satisfied) to 10 (extremely satisfied) EN. A patient will be considered very satisfied if he/she presents a satisfaction level ≥ 8. 5. The level of comfort will be assessed by a comfort scale ranging from 0 (not at all comfortable) to 10 (very comfortable patient).

Objectives To assess the association of low-dose Droperidol administration in the emergency department with changes in the QTc interval. Hypothesis Our study is designed to test the null hypothesis that there will be no clinically significant change in QTc interval after administration of 2.5mg of IV Droperidol during an emergency department visit.
