Accuracy of Point-of-Care-Ultrasonography in Confirming Shoulder Reduction in Emergency Departments.

Aims Accurate identification of the successful reduction of a dislocated shoulder could avoid additional episodes of procedural sedation and repeated performance of X-rays. The objective of this study was to assess the diagnostic accuracy of point-of-care-ultrasound (POCUS) in the confirmation of a successful joint reduction in patients with shoulder dislocation. Methods This was a single-centre, prospective observational study set in an urban academic ED in Ireland, with a convenience sample of adult patients with shoulder dislocation on X-ray. Ultrasound was performed on participants before and after joint reduction using a posterior approach technique. The operator's confidence levels were recorded after image acquisition. Results Thirty-three subjects were recruited. All dislocations were correctly identified on pre-reduction US, indicating a sensitivity of 100% (CI 89.42 - 100). Post-reduction US confirmed successful reduction in 30 subjects that were subsequently reported as such on X-Ray, giving it a specificity of 100% (CI 88.43 - 100). Failure to achieve reduction was correctly identified on US in three cases, resulting in post-reduction US Sensitivity of 100% (CI 29.24 - 100) and 100% accuracy (CI 89.42 - 100). Conclusion This study has shown that POCUS, with a posterior approach technique, has 100% sensitivity and specificity in confirming successful shoulder reduction in the ED.

European consensus on patient contact shielding.

Patient contact shielding has been in use for many years in radiology departments in order to reduce the effects and risks of ionising radiation on certain organs. New technologies in projection imaging and CT scanning such as digital receptors and automatic exposure control (AEC) systems have reduced doses and improved image consistency. These changes and a greater understanding of both the benefits and the risks from the use of shielding have led to a review of shielding use in radiology. A number of professional bodies have already issued guidance in this regard. This paper represents the current consensus view of the main bodies involved in radiation safety and imaging in Europe: European Federation of Organisations for Medical Physics, European Federation of Radiographer Societies, European Society of Radiology, European Society of Paediatric Radiology, EuroSafe Imaging, European Radiation Dosimetry Group (EURADOS), and European Academy of DentoMaxilloFacial Radiology (EADMFR). It is based on the expert recommendations of the Gonad and Patient Shielding (GAPS) Group formed with the purpose of developing consensus in this area. The recommendations are intended to be clear and easy to use. They are intended as guidance, and they are developed using a multidisciplinary team approach. It is recognised that regulations, custom and practice vary widely on the use of patient shielding in Europe and it is hoped that these recommendations will inform a change management program that will benefit patients and staff.

Patient shielding: The need for a European consensus statement.

Contact shielding has been in widespread use for the last 60-70 years aiming to protect against genetic effects, cancer, and other detriment. Since 2012, studies have begun to appear in the literature that question the continued use of such shielding, especially when radiographic technology has changed so much over the intervening period This literature has culminated in several professional bodies such as the American Association of Physicists in Medicine (AAPM) and the British Institute of Radiology (BIR) issuing guidance and statements recommending against the continued routine use of patient contact shielding. Many professional societies have also endorsed these statements. National statements on the matter continue to be produced. It is notable however that the major European bodies involved in diagnostic radiology and radiation safety have not to date issued a statement on patient shielding. This commentary looks at reasons for that and argues that it is now time for a European consensus statement on patient shielding. It is the authors belief that there are advantages to building on the work done by the AAPM and BIR, using the opportunity to amplify the statements, propagate the intent of the original statements, refine the message to deal with questions that have arisen since their publication. Α working group, Gonad and Patient Shielding (GAPS) has been formed by members from a) the European Federation of Organisations for Medical Physics (EFOMP), b) the Eurosafe Imaging initiative of the European Society of Radiology (ESR), c) the European Federation of Radiographers Societies (EFRS), d) EURADOS and e) the BIR to produce a joint statement on the proper application of patient shielding in diagnostic and interventional radiology.

The Doctor Can See You Now: A Key Stakeholder Study Into The Acceptability Of Ambulance Based Telemedicine.

Using telecommunications technology it would be possible to link a patient and paramedic to a Doctor in the Emergency Department (ED) at the point of first patient contact. A questionnaire-based study on telemedicine in the pre-hospital environment involving patients, paramedics, doctors and nurses in the ED, was performed to assess if they would want and accept telemedicine in pre-hospital emergency care. When asked 98.5% (55) of patients, 89% (11) of doctors, 76% (14) of nurses and 91% (42) of ambulance personnel saw the potential of an audio-visual link from the pre-hospital environment to the ED. The potential benefits were felt to be in diagnosis of time-dependent illnesses, time management, increased hospital preparedness for incoming patients and increased triage efficiency. Stakeholder enthusiasm for pre-hospital telemedicine must be met with the technological requirements to provide such a service. As noted by one patient a pre-hospital audio-visual link to the ED could be "potentially a life saving service".

Emergency Department Overcrowding And The Full Capacity Protocol Cross Over Study: What Patients Who Have Experienced Both Think About Being An Extra Patient In The Emergency Department Or On A Ward.

Hospital overcrowding is evidenced by Emergency Department (ED) overcrowding. The Full Capacity Protocol (FCP) is activated to move patients to temporary extra beds placed in the inpatient wards. This research aims to establish patient preferences when waiting for a ward bed in an Irish Hospital. The FCP in Beaumont Hospital was updated in the context of national guidelines. Patients' attitudes towards boarding in the ED as opposed to being in extra beds on the wards were assessed using a questionnaire based structured interview. Ninety nine patients took part in the study. Eighty three patients (83.83%) preferred being an additional patient on the ward, 12 (12.12%) had no preference and four (4.04%) preferred being boarded in the ED. Moving patients from the ED into extra beds on the wards creates space, facilitating safer care delivery. The vast majority of patients who have experienced both, prefer being boarded in the ward rather than in the ED.

Growing Old in the Emergency Department.

The research team were concerned that older patients requiring emergency admission seemed to wait longer for a hospital bed, and as such were disproportionately affected by Emergency Department overcrowding. To investigate this theory and explore any changes over time, a ten year dataset (2005-2014 inclusive) was extracted from the information systems at Beaumont Hospital, Dublin. This research examines the changing age profile of ED patients, identifies the relationship between age and the total time spent in the Emergency Department (Patient Experience Time (PET)), and examines the public belief that EDs are busiest in winter when reports of overcrowding and elderly patients waiting on trolleys get most media attention. The results highlight that the ED is busy all year round (but for different seasonal reasons) and point to an overdue need to plan for the current and future healthcare of older patients within and beyond acute hospitals.

Investigation of reference levels and radiation dose associated with abdominal EVAR (endovascular aneurysm repair) procedures across several European Centres.

OBJECTIVES: Endovascular aneurysm repair (EVAR) is considered the treatment of choice for abdominal aortic aneurysms with suitable anatomy. In order to improve radiation safety, European Directive (2013/59) requires member states to implement diagnostic reference levels (DRLs) in radio-diagnostic and interventional procedures. This study aimed to determine local DRLs for EVAR across five European centres and identify an interim European DRL, which currently remains unestablished. METHODS: Retrospective data was collected for 180 standard EVARs performed between January 2014 and July 2015 from five specialist centres in Ireland (n=2) and Italy (n=3). Data capture included: air kerma-area product (PKA), total air kerma at the reference point (Ka,r), fluoroscopic time (FT), number of acquisitions, frame rate of acquisition, type of acquisition, patient height, weight, and gender. RESULTS: The mean values for each site A, B, C, D, and E were: PKAs of 4343 ± 994 µGym2, 18,200 ± 2141 µGym2, 11,423 ± 1390 µGym2, 7796 ± 704 µGym2, 31,897 ± 5798 µGym2; FTs of 816 ± 92 s, 950 ± 150 s, 708 ± 70 s, 972 ± 61 s, 827 ± 118 s; and number of acquisitions of 6.72 ± 0.56, 10.38 ± 1.54, 4.74 ± 0.19, 5.64 ± 0.36, 7.28 ± 0.65, respectively. The overall pooled 75th percentile PKA was 15,849 µGym2. CONCLUSION: Local reference levels were identified. The pooled data has been used to establish an interim European DRL for EVAR procedures. KEY POINTS: • Abdominal endovascular aneurysm repair (EVAR) requires the use of ionising radiation. • EVAR is a minimally invasive procedure for the treatment of abdominal aortic aneurysms. • Diagnostic reference levels (DRLs) are used to monitor patient radiation exposure. • Radiation dose data was collected from five European centres for EVAR procedures. • Local DRLs have been determined and an interim European DRL is proposed.

Chemical cardioversion of recent-onset atrial fibrillation in the emergency department using vernakalant hydrochloride achieves safe and rapid restoration of sinus rhythm and facilitates same day discharge.

BACKGROUND: Vernakalant hydrochloride is a rapid-acting antiarrhythmic drug licensed in the EU since 2010 for the conversion of recent-onset atrial fibrillation with proven efficacy and safety when compared with placebo and amiodarone in randomized clinical trials. AIMS: The aim of our study was to determine the feasibility of same day discharge (following 2 h monitoring) from the emergency department after successful cardioversion using vernakalant hydrochloride. METHODS: Patients with recent-onset atrial fibrillation treated in the emergency department of a large Dublin academic teaching hospital. Patients received a maximum of two weight based 10 min infusions of vernakalant. Hypotensive events (>30% initial blood pressure), arrhythmias, conversion rates, and time to conversion were recorded. RESULTS: Sinus rhythm was restored in 35 out of 42 patients (83%) in an average of 8.8 min (median 8 min), average CHA2DS2-VASc of 0.92, HAS-BLED of 0.21 and average symptoms duration of 12 h. There were no hypotensive or arrhythmogenic events. 41 out of 42 patients were discharged after 2 h of monitoring. CONCLUSIONS: Vernakalant hydrochloride has provided a quick, safe, and practical means of achieving rapid restoration of sinus rhythm in our ED population with stable recent-onset AF who would otherwise not have undergone routine electrically cardioversion and same day discharge.

What Proportion of Patients Meet the Criteria for Uncomplicated Sepsis in an Irish Emergency Department?

Emergency medicine plays a central role in the early recognition of patients presenting to hospital with sepsis. However, the epidemiology of sepsis in the Irish Emergency Department (ED) setting has not been described. The primary aim of this study was to determine the proportion of adult ED patients who meet the current criteria for uncomplicated sepsis. This cross-sectional study was performed in the ED of Beaumont Hospital, Dublin. The clinical records of all patients presenting to the ED over a four-week period were retrospectively screened to determine if they met the current Health Service Executive (HSE) criteria for uncomplicated sepsis. Overall, 3,585 adult patients attended the ED during the study period, with 152 patients meeting the criteria for uncomplicated sepsis. The proportion of ED patients who met the criteria for uncomplicated sepsis was 4.24% (95% CI 3.57-4.91%).

DVT presentations to an Emergency Department: A study of guideline based care and decision making.

Pre-test probability scoring and blood tests for deep venous thrombosis (DVT) assessment are sensitive but not specific leading to increased demands on radiology services. 385 patients presenting to an Emergency Department with suspected DVT were studied to explore our actual work up of patients with possible DVT relating to risk stratification, further investigation and follow up. Of the 205 patients with an initially negative scan, 36 (17.6%) were brought for review to the Emergency Department Consultant clinic. 34 (16.6%) patients underwent repeat compression ultrasound with 5 (2.4%) demonstrating a DVT on the second scan. Repeat compression ultrasound scans were performed on 34 (16.6%) of patients with an initially negative scan with essentially the same diagnostic yield as other larger studies where 100% of such patients had repeat scanning. Where there is ongoing concern, repeat above knee compression ultrasound within one week will pick up a small number of deep venous thromboses.

A New Design of a Lead-Acrylic Shield for Staff Dose Reduction in Radial and Femoral Access Coronary Catheterization.

PURPOSE: Today's standard radiation protection during coronary angiography and percutaneous coronary interventions is the combined use of lead acrylic shields and table-mounted lower body protection. Ambient dose measurements, however, have shown that these protection devices need improvement. MATERIALS AND METHODS: Using an anthropomorphic physical phantom, various scenarios were investigated with respect to personnel exposure: a) enlarging the shield b) adding a flexible protective curtain to the bottom side of the shield, and c) application of radioprotective patient drapes. For visualization of the dose reduction effect, Monte Carlo simulations were performed. RESULTS: The flexible curtain in contact with the patient's body reduces the ambient dose rate at the operator's position by up to (87.5% ± 7.1) compared to the situation with the bare shield. The use of both the flexible curtain and the patient drape reduces the ambient dose rate by up to (90.8% ± 7). Similar results were achieved for the assisting personnel when they were positioned next to the operator. In addition, the enlarged shield provides better protection of the head region of tall operators. CONCLUSION: Adding a flexible protective curtain to the bottom side of the shield can protect operators from high doses, especially for body parts which are not protected by lead aprons, e.g. head, and eye lenses. This may be important with respect to lower dose limits for eye lenses in future. The protective effect in real-life working conditions is still being evaluated in an ongoing clinical study. KEY POINTS: Lead acrylic shields need improvement for a better protection of head and eye lenses. An additional flexible lead curtain at the bottom of the shield can considerably reduce the operator dose. Using the additional lead curtain, lighter protection clothing can be worn. Special eye protection may be no longer needed in most applications.

Referral letters to the emergency department: is the medication list accurate?

Medication errors are common when patients transfer across healthcare boundaries. This study was designed to investigate the quality of information on medicines provided by general practitioners (GPs) on emergency department (ED) referral letters. A convenience sample of referral letters to the ED of a teaching hospital was reviewed. The medication list and/or patient's drug allergy status were noted. Medicines reconciliation including patient (or carer) interview was conducted to determine the patient's actual home medication list. This was compared with the GP list and any discrepancies were identified and addressed. A total of 92 referral letters were included in the analysis of which 60 were computer-generated and 32 were hand-written. GPs provided dose and frequency of administration information in 47 (51%) of the letters sampled i.e. 44 (71%) computer-generated versus 3 (10%) hand-written; p < 0.001. In addition, the patient was taking their medicines exactly as per the GP list in 20 (22%) of cases. The patient's drug allergy status was documented in 13 (14%) of the letters.

Arrest in hospital: a study of in hospital cardiac arrest outcomes.

The effect of advances in cardiac arrest management over the last five decades on in-hospital cardiac arrest survival rates is not clear. Data on 212 arrests between January 2010 and May 2013 were retrospectively analyzed by means of an audit form based upon the Utstein template for in-hospital cardiac arrest, with a view to identifying significant associations between arrest characteristics and return of spontaneous circulation or survival to discharge. Significant associations were identified between return of spontaneous circulation and location (ward, 36 patients (38%) vs. ICU, 33 Patients (56%); P = 0.032), whether an arrest was witnessed or not (82 patients (52%) vs. 9 patients (30%); P = 0.029), whether the initial rhythm was shockable or non-shockable (28 patients (85%) vs. 38 patients (31%); P < 0.001), whether the first dose of adrenaline was administered within 2 minutes of arrest onset or later (13 patients (54%) vs. 12 patients (28%); P = 0.04).

Deep brain stimulation in ireland for Parkinson's disease and essential tremor.

Deep brain stimulation (DBS) is highly effective neurosurgery for idiopathic Parkinson's disease (IPD), essential tremor (ET) and primary dystonia. DBS involves stereotactic surgical implantation of a battery-operated stimulator into deep brain nuclei. Irish patients are referred abroad for DBS and have to travel repeatedly for pre and post-operative care resulting in stress, anxiety and hardship. Safe pre and post-operative care of these complex, ageing patients is compromised by the absence of a DBS service in Ireland. Moreover, both DBS surgery and the subsequent post-operative care abroad incurs substantial cost to the state. The Dublin Neurological Institute at the Mater Misericordiae University Hospital (DNI) is a non-profit institute for the care of patients with neurological diseases. The DNI developed, in collaboration with the Mater Private Hospital (MPH) and the Walton Centre, Liverpool, a DBS programme in 2008/2009. We performed DBS at the Mater Campus on three carefully selected patients from a cohort of movement disorder patients attending the DNI and continue to provide pre-operative assessment and post operative care for patients following DBS in Ireland and abroad.
