    The Impact of Implementing ‘Fast-Track’ Streaming for Complex Walk-in Patients in an Emergency Department Lee Patient ED Nursing Lead Transformation Tom Sagdahl ED Matron Background Mean initial assessment times Jun-15 Jul-15 Apr-15 Many EDs have now developed Rapid Assessment and Treatment (RAT) models. This is the process of undertaking a rapid patient assessment and determining what investigations and immediate treatment is needed (1). This approach takes advantage of time efficiencies from parallel processing. Studies suggest there are advantages of this process including a reduction 20 in time to treatment, length of stay, left without being seen rates (3) and improved patient care 19 and experience (4). 18 17 16 At St Thomas’ (as in many ED’s), RAT is undertaken in the Major treatment area and walk-in 15 patients are assessed using a traditional nurse triage/assessment process. For patients with 14 complex needs, this can often mean there is a considerable delay in reaching the appropriate 13 12 treatment area and having a RAT assessment. At St Thomas’, walk-in patients were streamed 11 as they arrived which aimed to risk assess patients and direct to the most appropriate care. 10 This process however was only in operation from 10.00 to 20.00 each day. 9 (minutes) 8 7 6 5 Case for Change 4 At St Thomas’ ED work was undertaken by the emergency nursing team working with the Trust time assessment initial Mean 3 2 Transformation team and 20:20 to review the initial assessment process.

  • The Role of Emergency Nurses in Emergency Preparedness and Response
    The Role of Emergency Nurses in Emergency Preparedness and Response Description Hospitals, and especially emergency departments (EDs), are an essential link in the medical system for emergency preparedness planning, response, and recovery.1 As a result, emergency nurses may routinely encounter patients who have been exposed to hazardous materials or infectious diseases, who are victims of no-notice events, or who are evacuees from an immediate threat to life. These patients may present via the emergency medical system, by private vehicle, or without prior notification and unrelated to a disaster.2–5 Disaster affected patients might also present to the ED in large volumes, creating a surge in patient visits, which can paralyze EDs that are not prepared. The United States Department of Homeland Security’s National Response Framework describes a disaster as “… any natural or manmade incident, including terrorism, which results in extraordinary levels of mass casualties, damage, or disruption severely affecting the population, infrastructure, environment, economy, national morale, or government functions.”16(p1) The increased risk associated with climate change and the need for coordination across the healthcare community to respond to the health effects of climate-related emergencies have been highlighted by the World Health Organization (WHO). Both the increased risk and the need for coordination requires focus as disaster plans are developed.6 Over the past decade more severe weather events associated with climate change have resulted in loss of life, injuries, and public health impacts.7 Optimal care for disaster patients is best achieved using a systematic, standardized approach across all facets of the healthcare system.1,8 A leading method for preparing to manage all types of disaster events is an all-hazards, capability-based approach to preparedness.

  • Effects of a Telephone Follow-Up Call on Patient Satisfaction in the Emergency Department
    Running head: PATIENT SATISFACTION 1 Effects of a Telephone Follow-Up Call on Patient Satisfaction in the Emergency Department Kathryn McCary, Cynthia Hestermann, and Abby Richardson Creighton University PATIENT SATISFACTION 2 Abstract Problem: Patient satisfaction has been identified as a key element of success in a competitive healthcare market, being used as an indicator of quality care as well as reimbursement incentives. Emergency Departments (ED) can have an important impact on patient satisfaction, as the ED can be the initial hospital contact for many patients. The problem identified for this project is the need for high patient satisfaction in the ED setting. Purpose: To determine the effectiveness of a telephone follow up call (TFC) on patient satisfaction. Methods: This study was conducted at two EDs within a multi-hospital, non-profit system. Sampled patients received a follow up call from a trained registered nurse within 72 hours of discharge, based on previously established hospital protocol. The sample inclusion criteria consisted of: (1) a patient in the ED of one of two study hospitals, (2) an adult over 19 years of age correlating with Nebraska state law, (3) English speaking, (4) access to a working telephone, and (5) verbal consent to participate in the study. Patients were asked to participate in a satisfaction survey following the initial follow-up call. Participants were asked 3 questions for the survey and demographically categorized by gender and age. Results: One hundred three patients were included in the study. Of these patients, 68.9% were female, 31.1% were male. Twenty-two point 3 percent of the patients contacted were between 19-29 years old, 19.4% of the patients were between 30-39 years old, 13.6% of the patients were between 40-49 years old, 15.5% of the patients were between 50-59 years old, 9.7% of the total patients were between 60-69 years old, 9.7% of the patients were between 70-79 years old, and 9.7% of the patients were over the age of 80.

  • Nursing Documentation in the Emergency Department: Nurses’ Perspectives
    Title Page NURSING DOCUMENTATION IN THE EMERGENCY DEPARTMENT: NURSES’ PERSPECTIVES by Paula Caroline Grainger A thesis submitted to Victoria University of Wellington, New Zealand in partial fulfilment of the requirements for the degree of Master of Nursing (Clinical) Victoria University of Wellington 2007 Grainger (2007) Nursing Documentation In The Emergency Department: Nurses’ Perspectives Abstract Nursing documentation is a required aspect of care, but for various reasons it can be curtailed. Nursing records are a critical aspect of communication and without them coordinated and safe care can be difficult to achieve. Study aim: To explore emergency nurses’ perspectives and practices about the quality, importance and value of emergency nursing documentation in relation to their personal beliefs, past experiences and preferred systems of documentation; the practical and contextual factors that influence documentation practices within an emergency department (ED); their interests in documentation tools or systems; and their interests in relation to further development of documentation practices and systems. Methodology and design: A qualitative descriptive study (informed by Sandelowski). Ten emergency nurses from one ED in New Zealand were recruited. Participants were interviewed using interactive interview methods, and completed a Likert scale to identify the relevance of internationally recognised general influences on documentation to their own practices in the context of an ED. Findings: The participants’ practices were influenced by factors in the workplace including competing priorities for time e.g. care provision vs. documentation, competition for access to patient records, and extant culture in relation the purpose, content and frameworks for documentation. Documentation practices were influenced by the participant’s own clinical histories, philosophies, familiarity with particular frameworks and education.

  • Ultrasound Guided Intravenous Access by Nursing Versus Resident Staff in a Community Based Teaching Hospital: a (Noninferiority) Trial

Link Wilson,1 and Godwin Dogbey2 1 Emergency Department, Southern Ohio Medical Center, Portsmouth, OH 45662, USA 2CORE Research Office, Ohio University Heritage College of Osteopathic Medicine, Athens, OH 45701, USA Correspondence should be addressed to Thomas Carter; [email protected] Received 28 May 2015; Revised 15 July 2015; Accepted 19 August 2015 Academic Editor: Wen-Jone Chen Copyright © 2015 Thomas Carter et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Objectives. Ultrasound (US) guidance is a safe and effective method for peripheral intravenous (IV) catheter placement. However, no studies have directly compared the success rate of emergency medicine (EM) residents and nurses at using this technique especially in community hospital settings. This prospective “noninferiority” study sought to demonstrate that nursing staff are at least as successful as EM residents at placing US guided IVs. Methods. A group of 5 EM residents and 11 nurse volunteers with at least two years’ experience underwent training sessions in hands-on practice and didactic instruction with prospective follow-up. Two failed attempts on a patient using standard approach by an emergency department (ED) nurse were deemed to be “difficult sticks” and randomly assigned to either a nurse or resident, based on the day they presented.

Mullennix, BSN, RN, CEN Drew Peklo, BSN, RN, CEN Charles Monaghan, BSN, RN, CEN Chad Galdys, BSN, RN, EMT-B January 16, 2015 Evidence NK3-3, USGPIV PowerPoint Education Objectives ■ Discuss the clinical significance of difficult IV access ■ Review evidence-based research in support of USGPIV access in the ED ■ Demonstrate knowledge of upper arm anatomy ■ Demonstrate critical safety steps when performing USGPIV access ■ Demonstrate proper technique when using the Bard ® guidewire catheter for USGPIV cannulation ■ Demonstrate proper documentation of USGPIV placement 2 Evidence NK3-3, USGPIV PowerPoint Education Clinical Significance Why do we need to learn to use Ultrasound Guided Peripheral Intravenous in the ED? ■ Conditions such as obesity, chronic illness, hypovolemia, IV drug abuse and vasculopathy can challenge the emergency nurse in obtaining IV access. ■ Difficulty obtaining peripheral intravenous (PIV) access can delay treatment for patients in the emergency department (ED). ■ Patients who experience multiple PIV attempts in the ED may receive a central venous catheter (CVC) due to lack of suitable PIV sites. 3 Evidence NK3-3, USGPIV PowerPoint Education Evidence to Support the Use of USGPIV ■ ENA gives the use of Ultrasound-guided access a level A (highest recommendation) as a viable option for nurses for those patients with known difficult access. ■ Empirical support is evident in current literature, including systematic reviews and meta-analysis on the use of USGPIV cannulation by RN’s to increase the success rate of establishing PIV access in ED patients with difficult access. ■ Some studies have presented that there may be a correlation in decreasing central venous catheter insertion rates in the ED with a successful USGPIV program.
