Mobile emergency department care to nursing home residents: a novel outreach service.

BACKGROUND: Every month, 6% of Danish nursing home residents are admitted to hospital. However, these admissions might have limited benefits and are associated with an increased risk of complications. We initiated a new mobile service comprising consultants performing emergency care in nursing homes. OBJECTIVE: Describe the new service, the recipients of this service, hospital admission patterns and 90-day mortality. DESIGN: A descriptive observational study. MODEL: When an ambulance is requested to a nursing home, the emergency medical dispatch centre simultaneously dispatches a consultant from the emergency department who will provide an emergency evaluation and decisions regarding treatment at the scene in collaboration with municipal acute care nurses. METHOD: We describe the characteristics of all nursing home contacts from 1st November 2020 to 31st December 2021. The outcome measures were hospital admissions and 90-day mortality. Data were extracted from the patients' electronic hospital records and prospectively registered data. RESULTS: We identified 638 contacts (495 individuals). The new service had a median of two (interquartile range: 2-3) new contacts per day. The most frequent diagnoses were related to infections, unspecific symptoms, falls, trauma and neurologic disease. Seven out of eight residents remained at home following treatment, 20% had an unplanned hospital admission within 30 days and 90-day mortality was 36.4%. CONCLUSION: Transitioning emergency care from hospitals to nursing homes could present an opportunity for providing optimised care to a vulnerable population and limiting unnecessary transfers and admissions to hospitals.

Ultra-low dose computed tomography of the chest in an emergency setting: A prospective agreement study.

Ultra-low dose computed tomography (ULD-CT) assessed by non-radiologists in a medical Emergency Department (ED) has not been examined in previous studies. To (i) investigate intragroup agreement among attending physicians caring for ED patients (i.e., radiologists, senior- and junior clinicians) and medical students for the detection of acute lung conditions on ULD-CT and supine chest X-ray (sCXR), and (ii) evaluate the accuracy of interpretation compared to the reference standard. In this prospective study, non-traumatic patients presenting to the ED, who received an sCXR were included. Between February and July 2019, 91 patients who underwent 93 consecutive examinations were enrolled. Subsequently, a ULD-CT and non-contrast CT were performed. The ULD-CT and sCXR were assessed by 3 radiologists, 3 senior clinicians, 3 junior clinicians, and 3 medical students for pneumonia, pneumothorax, pleural effusion, and pulmonary edema. The non-contrast CT, assessed by a chest radiologist, was used as the reference standard. The results of the assessments were compared within each group (intragroup agreement) and with the reference standard (accuracy) using kappa statistics. Accuracy and intragroup agreement improved for pneumothorax on ULD-CT compared with the sCXR for all groups. Accuracy and intragroup agreement improved for pneumonia on ULD-CT when assessed by radiologists and for pleural effusion when assessed by medical students. In patients with acute lung conditions ULD-CT offers improvement in the detection of pneumonia by radiologists and the detection of pneumothorax by radiologists as well as non-radiologists compared to sCXR. Therefore, ULD-CT may be considered as an alternative first-line imaging modality to sCXR for non-traumatic patients who present to EDs.

Healthcare professionals' experience with emergency department-based acute care performed within nursing homes.

BACKGROUND: hospital admissions of residents from nursing homes often lead to delirium, infections, mortality and reduced functional capacity. We initiated a new service, 'emergency department-based acute care service', maintained by consultants from an emergency department (ED) moving emergency care from the hospitals into nursing homes. OBJECTIVE: this study explored healthcare professionals' experiences with this service. DESIGN: qualitative semi-structured focus group discussions. INTERVENTION/SETTING: the new service provides acute on-site evaluation and treatment to nursing home residents following calls to the emergency dispatch centre. METHODS: we conducted focus groups with general practitioners, prehospital personnel, municipal acute care nurses, ED staff and nursing home staff. The analysis was performed using the iterative and explorative approach, 'systematic text condensation'. RESULTS: the participants considered the service as a meaningful and appropriate alternative to hospital admission, as the treatment can be tailored to meet the residents' wishes and daily capabilities. This was experienced to promote dignity for the residents by reducing unnecessary transfers to the ED and the residents could remain in familiar surroundings with staff who knew their habitual behaviour and history. The nursing home staff contributed valuable information to the ED consultants' decision-making. The service made it possible to base the decision-making on complete patient pictures, as the ED consultants had the time to get to understand the residents. CONCLUSION: acute care at nursing homes provides an alternative to routine admissions to hospitals and enables healthcare professionals to provide more dignity in the care of nursing home residents.

Prehospital emergency medical technicians can perform ultrasonography and blood analysis in prehospital evaluation of patients with chronic obstructive pulmonary disease: a feasibility study.

INTRODUCTION: Crowding of the emergency departments is an increasing problem. Many patients with an exacerbation of chronic obstructive pulmonary disease (COPD) are often treated in the emergency departments for a very short period before discharged to their homes. It is possible that this treatment could take place in the patients' homes with sufficient diagnostics supporting the treatment. In an effort to keep the diagnostics and treatment of some of these patients in their homes and thus to reduce the patient load at the emergency departments, we implemented a prehospital treat-and-release strategy based on ultrasonography and blood testing performed by emergency medical technicians (EMT) or paramedics (PM) in patients with acute exacerbation of COPD. METHOD: EMTs and PMs were enrolled in a six-hour educational program covering ultrasonography of the lungs and point of care blood tests. During the seasonal peak of COPD exacerbations (October 2018 - May 2019) all patients who were treated by the ambulance crews for respiratory insufficiency were screened in the ambulances. If the patient had uncomplicated COPD not requiring immediate transport to the hospital, ultrasonographic examination of the lungs, measurements of C-reactive protein and venous blood gases analyses were performed. The response to the initial treatment and the results obtained were discussed via telemedical consultation with a prehospital anaesthesiologist who then decided to either release the patient at the scene or to have the patient transported to the hospital. The primary outcome was strategy feasibility. RESULTS: We included 100 EMTs and PMs in the study. During the study period, 771 patients with respiratory insufficiency were screened. Uncomplicated COPD was rare as only 41patients were treated according to the treat-and-release strategy. Twenty of these patients (49%) were released at the scene. In further ten patients, technical problems were encountered hindering release at the scene. CONCLUSION: In a few selected patients with suspected acute exacerbations of COPD, it was technically and organisationally feasible for EMTs and PMs to perform prehospital POCT-ultrasound and laboratory testing and release the patients following treatment. None of the patients released at the scene requested a secondary ambulance within the first 48 h following the intervention.

[Findings in post-mortem CT and autopsy in a 53-year-old-man with COVID-19].

In this case report, a 53-year old man died after ten days with fever and coughing and was tested positive for coronavirus disease 2019 (COVID-19). A post-mortem CT disclosed ground-glass opacities with focal consolidation in both lungs. At autopsy, the lungs were dark and heavy with increased consistency and without pleural fibrin. Microscopy of lung tissue showed diffuse alveolar damage with hyaline membranes, sparse chronic interstitial inflammation and foci of bronchopneumonia. The deceased was a non-smoker, who did not suffer from a serious illness. He was overweight (BMI = 34 kg/m2), an emerging predictor for poor outcome of COVID-19.

Comparison of Acute Versus Subacute Coronary Angiography in Patients With NON-ST-Elevation Myocardial Infarction (from the NONSTEMI Trial).

The optimal timing of coronary angiography (CAG) in high-risk patients with acute coronary syndrome without persisting ST-segment elevation (NST-ACS) remains undetermined. The NON-ST-Elevation Myocardial Infarction trial aimed to compare outcomes in NSTE-ACS patients randomized to acute CAG (STEMI-like approach) with patients randomized to medical therapy and subacute CAG. We randomized 496 patients with suspected NST-ACS based on symptoms and significant regional ST depressions and/or elevated point-of-care troponin T (POC-cTnT) (≥50 ng/l) to either acute CAG (<2 hours, n = 245) or subacute CAG (<72 hours, n = 251). The primary end point was a composite of all-cause death, reinfarction, and readmission with congestive heart failure within 1 year from randomization. A final acute coronary syndrome (ACS) diagnosis was assigned to 429 (86.5%) patients. The median time from randomization to revascularization was 1.3 hours in the acute CAG group versus 51.1 hours in the subacute CAG group (p <0.001). The composite end point occurred in 25 patients (10.2%) in the acute CAG group and 29 (11.6%) in the subacute CAG group, p = 0.62. The acute CAG group had a 1-year all-cause mortality of 5.7% compared with 5.6% in the subacute CAG group, p = 0.96. In conclusion, neither the composite end point of all-cause death, reinfarction, and readmission with congestive heart failure nor mortality differed between an acute and subacute CAG approach in NSTE-ACS patients. However, identification of NSTE-ACS patients in the prehospital phase and direct triage to an invasive center is feasible, safe and may facilitate early diagnosis and revascularization.

Prehospital intravenous fentanyl administered by ambulance personnel: a cluster-randomised comparison of two treatment protocols.

BACKGROUND: Prehospital acute pain is a frequent symptom that is often inadequately managed. The concerns of opioid induced side effects are well-founded. To ensure patient safety, ambulance personnel are therefore provided with treatment protocols with dosing restrictions, however, with the concomitant risk of insufficient pain treatment of the patients. The aim of this study was to investigate the impact of a liberal intravenous fentanyl treatment protocol on efficacy and safety measures. METHODS: A two-armed, cluster-randomised trial was conducted in the Central Denmark Region over a 1-year period. Ambulance stations (stratified according to size) were randomised to follow either a liberal treatment protocol (3 µg/kg) or a standard treatment protocol (2 µg/kg). The primary outcome was the proportion of patients with sufficient pan relief (numeric rating scale (NRS, 0-10) < 3) at hospital arrival. Secondary outcomes included abnormal vital parameters as proxy measures of safety. A multi-level mixed effect logistic regression model was applied. RESULTS: In total, 5278 patients were included. Ambulance personnel following the liberal protocol administered higher doses of fentanyl [117.7 µg (95% CI 116.7-118.6)] than ambulance personnel following the standard protocol [111.5 µg (95% CI 110.7-112.4), P = 0.0001]. The number of patient with sufficient pain relief at hospital arrival was higher in the liberal treatment group than the standard treatment group [44.0% (95% CI 41.8-46.1) vs. 37.4% (95% CI 35.2-39.6), adjusted odds ratio 1.47 (95% CI 1.17-1.84)]. The relative decrease in NRS scores during transport was less evident [adjusted odds ratio 1.18 (95% CI 0.95-1.48)]. The occurrences of abnormal vital parameters were similar in both groups. CONCLUSIONS: Liberalising an intravenous fentanyl treatment protocol applied by ambulance personnel slightly increased the number of patients with sufficient pain relief at hospital arrival without compromising patient safety. Future efforts of training ambulance personnel are needed to further improve protocol adherence and quality of treatment. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT02914678 ).

Predictive value of routine point-of-care cardiac troponin T measurement for prehospital diagnosis and risk-stratification in patients with suspected acute myocardial infarction.

OBJECTIVE: The purpose of this study was to determine the predictive value of routine prehospital point-of-care cardiac troponin T measurement for diagnosis and risk stratification of patients with suspected acute myocardial infarction. METHODS AND RESULTS: All prehospital emergency medical service vehicles in the Central Denmark Region were equipped with a point-of-care cardiac troponin T device (Roche Cobas h232) for routine use in all patients with a suspected acute myocardial infarction. During the study period, 1 June 2012-30 November 2015, prehospital point-of-care cardiac troponin T measurements were performed in a total of 19,615 cases seen by the emergency medical service and 18,712 point-of-care cardiac troponin T measurements in 15,781 individuals were matched with an admission. A final diagnosis of acute myocardial infarction was confirmed in 2187 cases and a total of 2150 point-of-care cardiac troponin T measurements (11.0%) had a value ≥50 ng/l, including 966 with acute myocardial infarction (sensitivity: 44.2%, specificity: 92.8%). Patients presenting with a prehospital point-of-care cardiac troponin T value ≥50 ng/l had a one-year mortality of 24% compared with 4.8% in those with values <50 ng/l, log-rank: p<0.001. The following variables showed the strongest association with mortality in multivariable analysis: point-of-care cardiac troponin T≥50 ng/l (hazard ratio 2.10, 95% confidence interval: 1.90-2.33), congestive heart failure (hazard ratio 1.93, 95% confidence interval: 1.74-2.14), diabetes mellitus (hazard ratio 1.42, 95% confidence interval: 1.27-1.59) and age, one-year increase (hazard ratio 1.08, 95% confidence interval: 1.08-1.09). CONCLUSIONS: Patients with suspected acute myocardial infarction and a prehospital point-of-care cardiac troponin T ≥50 ng/l have a poor prognosis irrespective of the final diagnosis. Routine troponin measurement in the prehospital setting has a high predictive value and can be used to identify high-risk patients even before hospital arrival so that they may be re-routed directly for advanced care at an invasive centre.

Editor's Choice-Acute versus subacute angiography in patients with non-ST-elevation myocardial infarction - the NONSTEMI trial phase I.

BACKGROUND: The 2015 European Society of Cardiology non-ST-elevation myocardial infarction (NSTEMI) guidelines recommend angiography within 24 h in high-risk patients with NSTEMI. An organized STEMI-like approach with pre-hospital or immediate in-hospital triage for acute coronary angiography (CAG) may be of therapeutic benefit but it remains unknown whether the patients can be properly diagnosed in the pre-hospital setting. We aim to evaluate whether it is feasible to diagnose patients with NSTEMI in the pre-hospital phase or immediately upon admission. METHODS AND RESULTS: We randomized 250 patients to either acute or subacute CAG (i.e. <72 h of admission). Pre-hospital electrocardiogram acquisition and point-of-care troponin-T measurement ensured that 148 (59%) patients were identified already in the ambulance, whereas the remaining 102 (41%) patients were identified immediately after hospital admission. An acute coronary syndrome was verified in 215 (86%) and NSTEMI in 159 (64%) patients. The CAG rate was significantly higher in the acute CAG group (98% vs. 87%, p<0.001). A culprit lesion was identified in 74% and 64% of the patients underwent coronary revascularization: acute CAG group: 53% percutaneous coronary intervention, 5% hybrid, 7% coronary artery bypass grafting; conventional treatment: 48% percutaneous coronary intervention, 2% hybrid, 14% coronary artery bypass grafting, p=0.32. In patients randomized to acute CAG, time from randomization to CAG was 1.1 h; in patients randomized to subacute CAG it was two days. Time from randomization to initial revascularization was 1.3 h versus 2.4 days, and the median hospital stay was 4.0 days versus 4.5 days. Among patients randomized to subacute CAG, 17% crossed over to acute CAG and 5% developed STEMI before catheterization. CONCLUSION: Diagnosing NSTEMI patients in the pre-hospital phase or immediately upon hospital admission is feasible. Acute CAG may impact the mode of revascularization and is associated with earlier revascularization and shorter hospital stay. The clinical benefit of acute CAG in NSTEMI patients remains to be clarified.

[Ambulance transportation and prehospital treatment in connection with admission for suspected acute myocardial infarction]. / Ambulancetransport og praehospital behandling ved indlaeggelse for formodet akut myokardieinfarkt.

INTRODUCTION: The aim was to describe ambulance transportation and pre-hospital treatment in connection with admission for suspected acute myocardial infarction. MATERIAL AND METHODS: For all patients with suspected acute coronary syndrome who were urgently admitted to the Cardiological Department, Odense University Hospital between 3 August 1998 and 6 December 1998, information about ambulance transportation and pre-hospital treatment was collected through interviews with the patients and study of ambulance records, admission notes, and hospital medical records. In addition, details of the regarding response times were obtained from Falck's emergency service and from nurses' papers. RESULTS: Altogether 279 patients (83%) were transported by ambulance. Half the ambulances arrived at the hospital after 34 minutes (range 11-140 minutes), but every third ambulance took more than 40 minutes to reach the hospital. The pre-hospital treatment of all the patients was: oxygen 69%, nitroglycerin sublingually 46%, nitrous oxide 2%, defibrillation 1.4%, acetylsalicylic acid 9%, morphine injection 8%, and ECG monitoring 57%. CONCLUSION: The study showed that there were quality problems, as every third ambulance took more than 40 minutes to reach the hospital. It also showed that acetylsalicylic acid and morphine were used only to a limited extent in a pre-hospital situation.
