Continuation of chronic antiplatelet therapy is not associated with increased need for transfusions: a cohort study in critically ill septic patients. BMC Anesthesiol 2024; 24:146. [PMID: 38627682 PMCID: PMC11022363 DOI: 10.1186/s12871-024-02516-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Accepted: 03/28/2024] [Indexed: 04/19/2024] Open
Abstract
BACKGROUND The decision to maintain or halt antiplatelet medication in septic patients admitted to intensive care units presents a clinical dilemma. This is due to the necessity to balance the benefits of preventing thromboembolic incidents and leveraging anti-inflammatory properties against the increased risk of bleeding. METHODS This study involves a secondary analysis of data from a prospective cohort study focusing on patients diagnosed with severe sepsis or septic shock. We evaluated the outcomes of 203 patients, examining mortality rates and the requirement for transfusion. The cohort was divided into two groups: those whose antiplatelet therapy was sustained (n = 114) and those in whom it was discontinued (n = 89). To account for potential biases such as indication for antiplatelet therapy, propensity score matching was employed. RESULTS Therapy continuation did not significantly alter transfusion requirements (discontinued vs. continued in matched samples: red blood cell concentrates 51.7% vs. 68.3%, p = 0.09; platelet concentrates 21.7% vs. 18.3%, p = 0.82; fresh frozen plasma concentrates 38.3% vs. 33.3%, p = 0.7). 90-day survival was higher within the continued group (30.0% vs. 70.0%; p < 0.001) and the Log-rank test (7-day survivors; p = 0.001) as well as Cox regression (both matched samples) suggested an association between continuation of antiplatelet therapy < 7 days and survival (HR: 0.24, 95%-CI 0.10 to 0.63, p = 0.004). Sepsis severity expressed by the SOFA score did not differ significantly in matched and unmatched patients (both p > 0.05). CONCLUSIONS The findings suggest that continuing antiplatelet therapy in septic patients admitted to intensive care units could be associated with a significant survival benefit without substantially increasing the need for transfusion. These results highlight the importance of a nuanced approach to managing antiplatelet medication in the context of severe sepsis and septic shock.

Health impact of borders: general reflections and a case study from the Polish-German border. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2024; 25:281-292. [PMID: 37046102 PMCID: PMC10096107 DOI: 10.1007/s10198-023-01588-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Accepted: 04/04/2023] [Indexed: 06/19/2023]
Abstract
BACKGROUND AND OBJECTIVE Political, economic, communicative and cultural borders still limit the accessibility of acute healthcare services for patients so that they frequently have to accept longer distances to travel to the next provider within their own country. In this paper, we analyze the impact of borders and opening of borders on acute medical care in hospitals and on patients in border regions. METHODS We develop a conceptual framework model of cross-border healthcare and apply it to the Polish-German border area. The model combines the distance decay effect, a catchment area analysis, economies of scale and the learning curve. RESULTS Borders have a major impact on acute medical care in hospitals and on patients. Setting of new borders will reduce the accessibility of health facilities for patients or require the establishment of new hospitals. Reopening borders might induce a vicious circle leading to the insolvency of a hospital which might result in poorer health for some patients. CONCLUSION Strong effort should be invested to overcome political and cultural borders to improve the health of the population in border regions. Similarly, increased cross-border acute healthcare must be seen in the context of rural health and the special situation of small rural hospitals in rural peripheral areas.

Cross-border simulation training for German and Polish emergency medical teams is feasible: conception and evaluation of a bilingual simulation training. BMC MEDICAL EDUCATION 2023; 23:863. [PMID: 37957612 PMCID: PMC10644418 DOI: 10.1186/s12909-023-04823-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 10/30/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND Cross-border cooperation of emergency medical services, institutions and hospitals helps to reduce negative impact of national borders and consecutive discrimination of persons living and working in border regions. This study aims to explore the feasibility and effectiveness of a cross-border bilingual simulation training for emergency medical services within an INTERREG-VA-funded project. METHODS Five days of simulation training for German and Polish paramedics in mixed groups were planned. Effectiveness of training and main learning objectives were evaluated as pre-post-comparisons and self-assessment by participants. RESULTS Due to COVID-19 pandemic, only three of nine training modules with n = 16 participants could be realised. Cross-border-simulation training was ranked more positively and was perceived as more useful after the training compared to pretraining. Primary survey has been performed using ABCDE scheme in 18 of 21 scenarios, whereas schemes to obtain medical history have been applied incompletely. However, participants stated to be able to communicate with patients and relatives in 10 of 21 scenarios. CONCLUSION This study demonstrates feasibility of a bilingual cross-border simulation training for German and Polish rescue teams. Further research is highly needed to evaluate communication processes and intra-team interaction during bilingual simulation training and in cross-border emergency medical services rescue operations.

Abstract
Aim of study This study aims to investigate feasibility and quality of a bilingual cardiopulmonary resuscitation training with interprofessional emergency teams from Germany and Poland. Methods As part of a cross-border European Territorial Cooperation (Interreg-VA) funded project a combined communication and simulation training was organised. Teams of German and Polish emergency medicine personnel jointly practised resuscitation. The course was held in both languages with consecutive translation.Quality of chest compression was assessed using a simulator with feedback application. Learning objectives (quality of cardiopulmonary resuscitation, adherence to guidelines, closed loop communication), and team performance were assessed by an external observer. Coopeŕs Team Emergency Assessment Measure questionnaire was used. Results Twenty-one scenarios with 17 participants were analysed. In all scenarios, defibrillation and medication were delivered with correct dosage and at the right time. Mean fraction of correct hand position was 85.7% ± 25.7 [95%-CI 74.0; 97.4], mean fraction of compression depth 75.1% ± 21.0 [95%-CI 65.6; 84.7], compression rate 117.7 min-1 ± 7.1 [95%-CI 114.4; 120.9], and chest compression fraction 83.3% ± 3.8 [95%-CI 81.6; 85.0].Quality of cardiopulmonary resuscitation was rated as "fair" to "good", adherence to guidelines as "good", and closed loop communication as "fair". Bilingual teams demonstrated good situational awareness, but lack of leadership and suboptimal overall team performance. Conclusion Bilingual and interprofessional cross-border resuscitation training in German and Polish tandem teams is feasible. It does not affect quality of technical skills such as high-quality chest compression but does affect performance of non-technical skills (e.g. closed loop communication and leadership).

Can drones save lives and money? An economic evaluation of airborne delivery of automated external defibrillators. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2023; 24:1141-1150. [PMID: 36309919 PMCID: PMC10406671 DOI: 10.1007/s10198-022-01531-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Accepted: 09/28/2022] [Indexed: 06/16/2023]
Abstract
BACKGROUND Out-of-hospital cardiac arrest is one of the most frequent causes of death in Europe. Emergency medical services often struggle to reach the patient in time, particularly in rural areas. To improve outcome, early defibrillation is required which significantly increases neurologically intact survival. Consequently, many countries place Automated External Defibrillators (AED) in accessible public locations. However, these stationary devices are frequently not available out of hours or too far away in emergencies. An innovative approach to mustering AED is the use of unmanned aerial systems (UAS), which deliver the device to the scene. METHODS This paper evaluates the economic implications of stationary AED versus airborne delivery using scenario-based cost analysis. As an example, we focus on the rural district of Vorpommern-Greifswald in Germany. Formulae are developed to calculate the cost of stationary and airborne AED networks. Scenarios include different catchment areas, delivery times and unit costs. RESULTS UAS-based delivery of AEDs is more cost-efficient than maintaining traditional stationary networks. The results show that equipping cardiac arrest hot spots in the district of Vorpommern-Greifswald with airborne AEDs with a response time < 4 min is an effective method to decrease the time to the first defibrillation The district of Vorpommern-Greifswald would require 45 airborne AEDs resulting in annual costs of at least 1,451,160 €. CONCLUSION In rural areas, implementing an UAS-based AED system is both more effective and cost-efficient than the conventional stationary solution. When regarding urban areas and hot spots of OHCA, complementing the airborne network with stationary AEDs is advisable.

Serum Biomarkers of a Pro-Neuroinflammatory State May Define the Pre-Operative Risk for Postoperative Delirium in Spine Surgery. Int J Mol Sci 2023; 24:10335. [PMID: 37373482 DOI: 10.3390/ijms241210335] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Revised: 06/09/2023] [Accepted: 06/12/2023] [Indexed: 06/29/2023] Open
Abstract
Advances in spine surgery enable technically safe interventions in older patients with disabling spine disease, yet postoperative delirium (POD) poses a serious risk for postoperative recovery. This study investigates biomarkers of pro-neuroinflammatory states that may help objectively define the pre-operative risk for POD. This study enrolled patients aged ≥60 scheduled for elective spine surgery under general anesthesia. Biomarkers for a pro-neuroinflammatory state included S100 calcium-binding protein β (S100β), brain-derived neurotrophic factor (BDNF), Gasdermin D, and the soluble ectodomain of the triggering receptor expressed on myeloid cells 2 (sTREM2). Postoperative changes of Interleukin-6 (IL-6), Interleukin-1β (IL-1β), and C-reactive protein (CRP) were assessed as markers of systemic inflammation preoperatively, intraoperatively, and early postoperatively (up to 48 h). Patients with POD (n = 19, 75.7 ± 5.8 years) had higher pre-operative levels of sTREM2 (128.2 ± 69.4 pg/mL vs. 97.2 ± 52.0 pg/mL, p = 0.049) and Gasdermin D (2.9 ± 1.6 pg/mL vs. 2.1 ± 1.4 pg/mL, p = 0.29) than those without POD (n = 25, 75.6 ± 5.1 years). STREM2 was additionally a predictor for POD (OR = 1.01/(pg/mL) [1.00-1.03], p = 0.05), moderated by IL-6 (Wald-χ2 = 4.06, p = 0.04). Patients with POD additionally showed a significant increase in IL-6, IL-1β, and S100β levels on the first postoperative day. This study identified higher levels of sTREM2 and Gasdermin D as potential markers of a pro-neuroinflammatory state that predisposes to the development of POD. Future studies should confirm these results in a larger cohort and determine their potential as an objective biomarker to inform delirium prevention strategies.

Duration of Surgery and Intraoperative Blood Pressure Management are Modifiable Risk Factors for Postoperative Neurocognitive Disorders Following Spine Surgery: Results of the Prospective CONFESS Study. Spine (Phila Pa 1976) 2023:00007632-990000000-00357. [PMID: 37195031 PMCID: PMC10368215 DOI: 10.1097/brs.0000000000004722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Accepted: 05/09/2023] [Indexed: 05/18/2023]
Abstract
STUDY DESIGN Prospective quasi-experimental observational study. OBJECTIVE To evaluate whether duration of surgery is a modifiable risk factor for postoperative delirium (POD) following spine surgery, and explore further modifiable risk factors. Additionally, we sought to investigate the association between POD and postoperative cognitive dysfunction (POCD) and persistent neurocognitive disorders (pNCD). SUMMARY OF BACKGROUND DATA Advances in spine surgery enable technically safe interventions in elderly patients with disabling spine disease. The occurrence of POD and delayed neurocognitive complications (e.g. POCD/pNCD) remain a concern, since these contribute to inferior functional outcomes and long-term care dependency following spine surgery. METHODS This prospective single-center study recruited patients aged ≥60 years and scheduled for elective spine surgery between 02/2018-03/2020. Functional (Barthel Index, BI) and cognitive outcomes (CERAD test battery; telephone MoCA) were assessed at baseline, three (V3) and twelve months postoperatively. The primary hypothesis was that duration of surgery predicts POD. Multivariable predictive models of POD included surgical and anesthesiological parameters. RESULTS Twenty-two percent of patients developed POD (n=22/99). In a multivariable model, duration of surgery (ORadj=1.61/hour [95%CI:1.20-2.30]), age (ORadj=1.22/year [95%CI:1.10-1.36]), and baseline deviations of intraoperative systolic blood pressure (25th percentile: ORadj=0.94/mmHg [95%CI:0.89-0.99]; 90th percentile: ORadj=1.07/mmHg [95%CI:1.01-1.14]) were significantly associated with POD. Postoperative cognitive scores generally improved (V3, ΔCERAD total z-score: 0.22±0.63). However, this positive group effect was counteracted by POD (beta:-0.87 [95%CI:-1.31--0.42]), older age (beta:-0.03/year [95%CI:-0.05--0.01]), and lack of functional improvement (ΔBI; beta:-0.04/point [95%CI:-0.06--0.02]). Cognitive scores at twelve months remained inferior in the POD group, adjusted for baseline cognition/age. CONCLUSIONS This study identified distinct neurocognitive effects following spine surgery, which are influenced by perioperative risk factors. Potential cognitive benefits are counteracted by POD, rendering its prevention critical in an aging population.

Individual perspectives and mental maps of working conditions and intention to stay of physicians in academic medicine. Front Psychol 2023; 14:1106501. [PMID: 37251059 PMCID: PMC10213555 DOI: 10.3389/fpsyg.2023.1106501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Accepted: 04/10/2023] [Indexed: 05/31/2023] Open
Abstract
Introduction Job satisfaction has a strong impact on the intention to stay which is an important aspect to counter skills shortage in academic medicine. The purpose of the three studies reported here is to find out what specific factors are relevant for the intention to stay and turnover intention of physicians in academic medicine -and what measures might have a positive impact on employee retention. Methods In an interview study combining qualitative and quantitative methods, we investigated how the individual mental representation of working conditions influences job satisfaction and its impact on the intention to stay. In total, 178 physicians from German university hospitals, residents, and physicians, in 15 departments of anesthesiology were interviewed and surveyed. In a first study, chief physicians participated in interviews about job satisfaction in academic hospitals. Answers were segmented into statements, ordered by topics, and rated according to their valence. In a second study, assistant physicians during and after their training period talked about strengths, weaknesses, and potential improvements of working conditions. Answers were segmented, ordered, rated, and used to develop a "satisfaction scale." In a third study, physicians participated in a computer-led repertory grid procedure composing 'mental maps' of job satisfaction factors, filled in the job satisfaction scale and rated if they would recommend work and training in their clinic as well as their intention to stay. Results Comparing the interview results with recommendation rates and intention to stay show that high workload and poor career perspectives are linked to a negative attitude. A positive attitude towards work environment and high intention to stay is based on sufficient personnel and technical capacities, reliable duty scheduling and fair salaries. The third study using repertory grids showed that the perception of current teamwork and future developments concerning work environment were the main aspects to improve job satisfaction and the intention to stay. Discussion The results of the interview studies were used to develop an array of adaptive improvement measure. The results support prior findings that job dissatisfaction is mostly based on generally known "hygiene factors" and whereas job satisfaction is due to individual aspects.

Potential to enhance telephone cardiopulmonary resuscitation with improved instructions - findings from a simulation-based manikin study with lay rescuers. BMC Emerg Med 2023; 23:36. [PMID: 37003971 PMCID: PMC10067171 DOI: 10.1186/s12873-023-00810-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 03/23/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Telephone-Cardiopulmonary Resuscitation (T-CPR) significantly increases rate of bystander resuscitation and improves patient outcomes after out-of-hospital cardiac arrest (OHCA). Nevertheless, securing correct execution of instructions remains a difficulty. ERC Guidelines 2021 recommend standardised instructions with continuous evaluation. Yet, there are no explicit recommendations on a standardised wording of T-CPR in the German language. We investigated, whether a modified wording regarding check for breathing in a German T-CPR protocol improved performance of T-CPR. METHODS A simulation study with 48 OHCA scenarios was conducted. In a non-randomised trial study lay rescuers were instructed using the real-life-CPR protocol of the regional dispatch centre and as the intervention a modified T-CPR protocol, including specific check for breathing (head tilt-chin lift instructions). Resuscitation parameters were assessed with a manikin and video recordings. RESULTS Check for breathing was performed by 64.3% (n = 14) of the lay rescuers with original wording and by 92.6% (n = 27) in the group with modified wording (p = 0.035). In the original wording group the head tilt-chin manoeuvre was executed by 0.0% of the lay rescuers compared to 70.3% in the group with modified wording (p < 0.001). The average duration of check for breathing was 1 ± 1 s in the original wording group and 4 ± 2 s in the group with modified wording (p < 0.001). Other instructions (e.g. check for consciousness and removal of clothing) were well performed and did not differ significantly between groups. Quality of chest compression did not differ significantly between groups, with the exception of mean chest compression depth, which was slightly deeper in the modified wording group. CONCLUSION Correct check for breathing seems to be a problem for lay rescuers, which can be decreased by describing the assessment in more detail. Hence, T-CPR protocols should provide standardised explicit instructions on how to perform airway assessment. Each protocol should be evaluated for practicability.

Digital transition in rural emergency medicine: Impact of job satisfaction and workload on communication and technology acceptance. PLoS One 2023; 18:e0280956. [PMID: 36693080 PMCID: PMC9873191 DOI: 10.1371/journal.pone.0280956] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Accepted: 01/11/2023] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND Tele-emergency physicians (TEPs) take an increasingly important role in the need-oriented provision of emergency patient care. To improve emergency medicine in rural areas, we set up the project 'Rural|Rescue', which uses TEPs to restructure professional rescue services using information and communication technologies (ICTs) in order to reduce the therapy-free interval. Successful implementation of ICTs relies on user acceptance and knowledge sharing behavior. METHOD We conducted a factorial design with active knowledge transfer and technology acceptance as a function of work satisfaction (high vs. low), workload (high vs. low) and point in time (prior to vs. after digitalization). Data were collected via machine readable questionnaires issued to 755 persons (411 pre, 344 post), of which 304 or 40.3% of these persons responded (194 pre, 115 post). RESULTS Technology acceptance was higher after the implementation of TEP for nurses but not for other professions, and it was higher when the workload was high. Regarding active communication and knowledge sharing, employees with low work satisfaction are more likely to share their digital knowledge as compared to employees with high work satisfaction. This is an effect of previous knowledge concerning digitalization: After implementing the new technology, work satisfaction increased for the more experienced employees, but not for the less experienced ones. CONCLUSION Our research illustrates that employees' workload has an impact on the intention of using digital applications. The higher the workload, the more people are willing to use TEPs. Regarding active knowledge sharing, we see that employees with low work satisfaction are more likely to share their digital knowledge compared to employees with high work satisfaction. This might be attributed to the Dunning-Kruger effect. Highly knowledgeable employees initially feel uncertain about the change, which translates into temporarily lower work satisfaction. They feel the urge to fill even small knowledge gaps, which in return leads to higher work satisfaction. Those responsible need to acknowledge that digital change affects their employees' workflow and work satisfaction. During such times, employees need time and support to gather information and knowledge in order to cope with digitally changed tasks.

Abstract
Hintergrund und Ziel Um die präklinische Notfallversorgung zu optimieren und aktuelle Herausforderungen zu bewältigen, wurde im Landkreis Vorpommern-Greifswald im Jahr 2017 ein Telenotarzt-System eingeführt. Es sollte aus medizinischer und ökonomischer Sicht geprüft werden, ob dies, insbesondere im ländlichen Raum, eine effiziente Ergänzung der präklinischen Notfallversorgung darstellt. Methodik Es wurden ca. 250.000 Einsatzdaten, vor und nach Einführung des Systems, über die Jahre 2015 bis 2020 ausgewertet und ein Prä-Post-Vergleich über die Einsatzstruktur erstellt. Die 3611 Einsätze der Telenotärztinnen und -ärzte (TNA) wurden nach medizinischen Indikationen und zeitlichen Faktoren analysiert sowie mit Einsätzen ohne TNA verglichen. Zusätzlich erfolgten eine Analyse der Gesamtkosten des neuen Versorgungskonzeptes sowie eine Kostenanalyse der prä- und innerklinischen Behandlungskosten ausgewählter Erkrankungen. Ergebnisse Das Einsatzspektrum des TNA umfasste alle Altersstufen mit verschiedenen Meldebildern, die zu 48,2 % eine mittlere Erkrankungsschwere (stationäre Behandlung erforderlich) hatten. Von Patient*innen und Mitarbeitenden wurde das System gut angenommen. Die Einsatzdaten zeigten einen signifikanten Rückgang der Notarztbeteiligung bei telenotarztfähigen Einsatzfahrzeugen um 20 %. Die jährlichen Kosten des Systems belaufen sich auf ca. 1,7 Mio. €. Schlussfolgerung Die Ergebnisse belegen die Vorteilhaftigkeit des TNA-Systems, sodass es über die Projektdauer hinaus implementiert wurde. Das System ist medizinisch sinnvoll, funktionsfähig sowie effizient und steht als Innovation für die Umsetzung in ganz Deutschland bereit.

Abstract
We analyzed symptoms and comorbidities as predictors of hospitalization in 710 outpatients in North-East Germany with PCR-confirmed SARS-CoV-2 infection. During the first 3 days of infection, commonly reported symptoms were fatigue (71.8%), arthralgia/myalgia (56.8%), headache (55.1%), and dry cough (51.8%). Loss of smell (anosmia), loss of taste (ageusia), dyspnea, and productive cough were reported with an onset of 4 days. Anosmia or ageusia were reported by only 18% of the participants at day one, but up to 49% between days 7 and 9. Not all participants who reported ageusia also reported anosmia. Individuals suffering from ageusia without anosmia were at highest risk of hospitalization (OR 6.8, 95% CI 2.5–18.1). They also experienced more commonly dyspnea and nausea (OR of 3.0, 2.9, respectively) suggesting pathophysiological connections between these symptoms. Other symptoms significantly associated with increased risk of hospitalization were dyspnea, vomiting, and fever. Among basic parameters and comorbidities, age > 60 years, COPD, prior stroke, diabetes, kidney and cardiac diseases were also associated with increased risk of hospitalization. In conclusion, due to the delayed onset, ageusia and anosmia may be of limited use in differential diagnosis of SARS-CoV-2. However, differentiation between ageusia and anosmia may be useful for evaluating risk for hospitalization.

Abstract
BACKGROUND In medical events, patients have to independently decide whom to contact: emergency medical services, medical on-call service or emergency department. OBJECTIVES Are Germans able to assess the urgency of medical events and choose the correct resource? MATERIALS AND METHODS In 2018 a nationwide anonymous telephone survey was done in Gabler-Haeder design. In all, 708 interviewees were presented with six medical scenarios. Participants were asked to rate urgency and to assess whether medical help was necessary within minutes to hours. Telephone numbers of emergency medical services and medical on-call service were inquired. RESULTS Urgency of different scenarios was often misjudged: in cases with high, medium, and low urgency the misjudgement rate were 20, 50, and 27%, respectively. If medical help was rated as necessary, some participants chose the wrong service: 25% would not call an ambulance in stroke or myocardial infarction. In cases with medium urgency, more respondents chose to consult an emergency department (38%) than to call medical on-call service (46%). CONCLUSIONS Knowledge regarding different options for treatment of medical events and competence to assess urgency seem to be too low. Beside efforts to increase health literacy, one solution might be to introduce a joint telephone number for emergency medical services and medical on-call service with a uniform assessment tool and appropriate allocation.

Abstract
IMPORTANCE A pharmacological approach to pain control after cesarean delivery is often insufficient on its own. Acupuncture is a promising method for mitigating postoperative pain and reducing postoperative opioid requirements. OBJECTIVE To evaluate the efficacy and effectiveness of acupuncture as an adjunctive therapy for pain control after cesarean delivery, compared with a placebo intervention and standard care alone. DESIGN, SETTING, AND PARTICIPANTS This single-center, placebo-controlled, patient- and assessor-blinded randomized clinical trial was conducted from January 13, 2015, to June 27, 2018, at a tertiary university hospital in Greifswald, Germany. Participants were women who were scheduled for elective cesarean delivery under spinal anesthesia and were randomized to either the acupuncture group (n = 60) or placebo group (n = 60). Another 60 consecutive patients who met the eligibility criteria and received the standard postoperative analgesia were selected to form a nonrandomized standard care group. The intention-to-treat analysis was performed from August 19, 2019, to September 13, 2019. INTERVENTIONS In addition to standard pain treatment, each patient in the acupuncture group received auricular and body acupuncture with indwelling intradermal needles, whereas patients in the placebo group were treated with nonpenetrating placebo needles. MAIN OUTCOMES AND MEASURES The primary outcome was pain intensity on movement, which was measured using an 11-item verbal rating scale. Secondary outcomes were analgesia-related adverse effects, analgesics consumption, time to mobilization and Foley catheter removal, quality of patient blinding to randomization, and patient satisfaction with treatment of pain. RESULTS A total of 180 female patients (mean [SD] age, 31 [5] years) were included in the intention-to-treat analysis. The mean pain intensity on movement in the acupuncture group on the first postoperative day was lower than in the placebo group (4.7 [1.8] vs 6.0 [2.0] points; Cohen d, 0.73; 95% CI, 0.31-1.01; P = .001) and the standard care group (6.3 [1.3] points; Cohen d, 1.01; 95% CI, 0.63-1.40; P < .001). On the first postoperative day, 59 patients (98%) in the acupuncture group were fully mobilized vs 49 patients (83%) in the placebo group (relative risk [RR], 1.18; 95% CI, 1.06-1.33; P = .01) and 35 patients (58%) in the standard care group (RR, 1.69; 95% CI, 1.36-2.09; P < .001). The Foley catheter was removed in a total of 57 patients (93%) from the acupuncture group vs 43 patients (72%) from the placebo group (RR, 1.33; 95% CI, 1.12-1.57; P = .003) and 42 patients (70%) from the standard care group (RR, 1.37; 95% CI, 1.14-1.62; P = .002). Other parameters were comparable across the 3 study groups. CONCLUSIONS AND RELEVANCE Results of this trial showed that acupuncture was safe and effective in reducing pain and accelerating mobilization of patients after cesarean delivery. With consideration for personnel and time expenditures, acupuncture can be recommended as routine, supplemental therapy for pain control in patients after elective cesarean delivery.

Blood Product Supply for a Helicopter Emergency Medical Service. Transfus Med Hemother 2022; 48:332-341. [PMID: 35082564 DOI: 10.1159/000519825] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 09/15/2021] [Indexed: 11/19/2022] Open
Abstract
Background Long patient transport times to trauma centers are a well-known problem in sparsely populated regions with a low hospital density. Transfusion of red blood cell concentrates (RBC) and plasma improves outcome of trauma patients with severe bleeding. Helicopter emergency services (HEMS) are frequently employed to provide early advanced medical care and to reduce time to hospital admission. Supplying HEMS with blood products allows prehospital transfusion and may help to prevent exsanguination or prolonged hemorrhagic shock. We have investigated the maintenance of blood product quality under air transport conditions and the logistical steps to introduce a HEMS blood depot into routine practice. Methods A risk analysis was performed and a validation plan developed. A special, commercially available transport container for blood products was identified. Maintenance of temperature conditions between 2 and 6°C in the box were monitored at ambient temperatures up to 35°C over 48 h. Quality of blood products before and after helicopter air transport were evaluated including (1) for RBCs: hemoglobin, hematocrit, hemolysis rate; (2) for thawed plasma: aPTT, INR, single clotting factor activities. The logistics for blood supply of the regional HEMS were developed by the transfusion service of the Greifswald University Hospital in collaboration with the in-hospital transport team, the HEMS team, and the HEMS operator. Results The transport container maintained a temperature below 6°C up to 36 h at 35°C ambient temperature. Vibration during helicopter operation did not impair quality of RBC and thawed plasma. To provide blood products for HEMS at least two transport containers and an additional set of cooling tiles is needed as the cooling tiles need a special temperature priming over 20 h. The two boxes were used at alternate days. To reduce wastage, RBCs and thawed plasmas were exchanged every fourth day and reintegrated into the blood bank inventory for further in-hospital use. Conclusions Supplying HEMS with RBCs and plasma is feasible. Helicopter transport has no negative impact on blood product quality. The logistic challenges require close collaboration between the HEMS team and the blood transfusion service.

Drones Delivering Automated External Defibrillators-Integrating Unmanned Aerial Systems into the Chain of Survival: A Simulation Study in Rural Germany. Resuscitation 2021; 172:139-145. [PMID: 34971721 DOI: 10.1016/j.resuscitation.2021.12.025] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/04/2021] [Accepted: 12/21/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND Community first responders (CFR) improve survival in out-of-hospital cardiac arrest (OHCA) but are often hampered by limited availability of public access defibrillation. Unmanned aerial systems (UAS) delivering automated external defibrillators (AED) directly to an OHCA site could help overcome this. We evaluated the feasibility of integrating UAS into the chain of survival in rural Northeast Germany. METHODS This simulation study explored UAS-AED delivery combined with a smartphone-based CFR dispatch. Five OHCA locations (A-E) were randomly selected. We routed a flight corridor to each of these sites from a corresponding UAS base; 50 OHCA scenarios with 10 flights per corridor were scheduled. All steps were accurately simulated, from a bystander finding the patient, making an emergency call, conducting dispatcher-assisted cardiopulmonary resuscitation, and simultaneous CFR plus UAS deployment, to the bystander and CFR interacting with UAS and AED. This process was time-tracked and video-recorded until defibrillation. RESULTS We performed 46 OHCA simulations. Missions were flown autonomously but needed pilot assistance during landing. Distances (km) and average time intervals from alert to defibrillation (td in min:sec±SD) were 0.4 (6:02±0:56), 2.29 (6:53±0:19), 4.0 (8:54±0:25), 7.43 (14:51±1:055), and 9.79 (15:51±1:16) for routes A to E, respectively. All participants were able to retrieve the AED within seconds after UAS landing and interacted safely with the UAS and AED. CONCLUSIONS Integrating airborne AED delivery into the chain of survival appeared feasible and safe but remains an experimental technology. Linking this with CFR potentially improves the availability of early public-access defibrillation, particularly in rural regions.

Anti-platelet factor 4 antibodies causing VITT do not cross-react with SARS-CoV-2 spike protein. Blood 2021; 138:1269-1277.

Abstract
Vaccine-induced immune thrombotic thrombocytopenia (VITT) is a severe adverse effect of ChAdOx1 nCoV-19 COVID-19 vaccine (Vaxzevria) and Janssen Ad26.COV2.S COVID-19 vaccine, and it is associated with unusual thrombosis. VITT is caused by anti-platelet factor 4 (PF4) antibodies activating platelets through their FcγRIIa receptors. Antibodies that activate platelets through FcγRIIa receptors have also been identified in patients with COVID-19. These findings raise concern that vaccination-induced antibodies against anti-SARS-CoV-2 spike protein cause thrombosis by cross-reacting with PF4. Immunogenic epitopes of PF4 and SARS-CoV-2 spike protein were compared using in silico prediction tools and 3D modeling. The SARS-CoV-2 spike protein and PF4 share at least 1 similar epitope. Reactivity of purified anti-PF4 antibodies from patients with VITT was tested against recombinant SARS-CoV-2 spike protein. However, none of the affinity-purified anti-PF4 antibodies from 14 patients with VITT cross-reacted with SARS-CoV-2 spike protein. Sera from 222 polymerase chain reaction-confirmed patients with COVID-19 from 5 European centers were tested by PF4-heparin enzyme-linked immunosorbent assays and PF4-dependent platelet activation assays. We found anti-PF4 antibodies in sera from 19 (8.6%) of 222 patients with COVID-19. However, only 4 showed weak to moderate platelet activation in the presence of PF4, and none of those patients developed thrombotic complications. Among 10 (4.5%) of 222 patients who had COVID-19 with thrombosis, none showed PF4-dependent platelet-activating antibodies. In conclusion, antibodies against PF4 induced by vaccination do not cross-react with the SARS-CoV-2 spike protein, indicating that the intended vaccine-induced immune response against SARS-CoV-2 spike protein is not the trigger of VITT. PF4-reactive antibodies found in patients with COVID-19 in this study were not associated with thrombotic complications.

Abstract
An elevated intra-abdominal pressure (IAP) above 12 mmHg is a pathological finding in critically ill patients. IAP are classified into different degrees of intra-abdominal hypertension and, in the presence of associated organ failure, as abdominal compartment syndrome. Both disease entities represent an underestimated factor in intensive care patients and are associated with increased mortality and prolonged intensive care and hospital stay. The measurement of intra-abdominal pressure in critically ill patients in intensive care units is not widely established and there is often considerable uncertainty regarding measurement conditions and methods. If risk factors are present, intra-abdominal pressure should be monitored every 4 hours. Bladder pressure measurement is the gold standard for determining intra-abdominal pressure. The measurement is a non-invasive, cost-effective, easy to perform bedside and safe method for the patient.

One out of three bystanders of out-of-hospital cardiac arrests shows signs of pathological psychological processing weeks after the incident - results from structured telephone interviews. Scand J Trauma Resusc Emerg Med 2021; 29:131.

Abstract
Background Witnessing an out-of-hospital cardiac arrest (OHCA) is a traumatic experience. This study analyses bystanders` psychological processing of OHCA. We examined the potential impact of bystanders performing resuscitation and the influence of the relationship between bystander and patient (stranger vs. family/friend of the patient) on the psychological processing. Methods A telephone interview survey with bystanders, who witnessed an OHCA of an adult patient was performed weeks after the event between December 2014 and April 2016. The semi-standardized questionnaire contained a question regarding the paramount emotion at the time of the interview. In a post-hoc analysis statements given in response were rated by independent researchers into the categories “signs of pathological psychological processing”, “physiological psychological processing” and “no signs of psychological distress due to the OHCA”. Results In this analysis 89 telephone interviews were included. In 27 cases (30.3%) signs of pathological psychological processing could be detected. Bystanders performing resuscitation had a higher rate of “no signs of psychological distress after witnessing OHCA” compared to those not resuscitating (54.7% vs. 26.7%, p < 0.05; relative risk 2.01; 95%CI 1.08, 3.89). No statistical significant differences in the psychological processing could be shown for gender, age, relationship to the patient, current employment in the health sector, location of cardiac arrest or number of additional bystanders. Conclusions One out of three bystanders of OHCA suffers signs of pathological psychological processing. This was independent of bystander´s age, gender and relationship to the patient. Performing resuscitation seems to help coping with witnessing OHCA. Supplementary Information The online version contains supplementary material available at 10.1186/s13049-021-00945-8.

Smartphone apps to support laypersons in bystander CPR are of ambivalent benefit: a controlled trial using medical simulation. Scand J Trauma Resusc Emerg Med 2021; 29:76.

Abstract
Background Bystander-initiated resuscitation is essential for surviving out-of-hospital cardiac arrest. Smartphone apps can provide real-time guidance for medical laypersons in these situations. Are these apps a beneficial addition to traditional resuscitation training? Methods In this controlled trial, we assessed the impact of app use on the quality of resuscitation (hands-off time, assessment of the patient’s condition, quality of chest compression, body and arm positioning). Pupils who have previously undergone a standardised resuscitation training, encountered a simulated cardiac arrest either (i) without an app (control group); (ii) with facultative app usage; or (iii) with mandatory app usage. Measurements were compared using generalised linear regression. Results 200 pupils attended this study with 74 pupils in control group, 65 in facultative group and 61 in mandatory group. Participants who had to use the app significantly delayed the check for breathing, call for help, and first compression, leading to longer total hands-off time. Hands-off time during chest compression did not differ significantly. The percentage of correct compression rate and correct compression depth was significantly higher when app use was mandatory. Assessment of the patient’s condition, and body and arm positioning did not differ. Conclusions Smartphone apps offering real-time guidance in resuscitation can improve the quality of chest compression but may also delay the start of resuscitation. Provided that the app gives easy-to-implement, guideline-compliant instructions and that the user is familiar with its operation, we recommend smartphone-guidance as an additional tool to hands-on CPR-training to increase the prevalence and quality of bystander-initiated CPR.

Telemedical emergency services: central or decentral coordination? HEALTH ECONOMICS REVIEW 2021; 11:7.

Abstract
BACKGROUND AND OBJECTIVE Teleemergency doctors support ambulance cars at the emergency site by means of telemedicine. Currently, each district has its own teleemergency doctor office (decentralized solution). This paper analyses the advantages and disadvantages of a centralized solution where several teleemergency doctors work in parallel in one office to support the ambulances in more districts. METHODS The service of incoming calls from ambulances to the teleemergency doctor office can be modelled as a queuing system. Based on the data of the district of Vorpommern-Greifswald in the Northeast of Germany, we assume that arrivals and services are Markov chains. The model has parallel channels proportionate to the number of teleemergency doctors working simultaneously and the number of calls which one doctor can handle in parallel. We develop a cost function with variable, fixed and step-fixed costs. RESULTS For the district of Greifswald, the likelihood that an incoming call has to be put on hold because the teleemergency doctor is already fully occupied is negligible. Centralization of several districts with a higher number of ambulances in one teleemergency doctor office will increase the likelihood of overburdening and require more doctors working simultaneously. The cost of the teleemergency doctor office per ambulance serviced strongly declines with the number of districts cooperating. DISCUSSION The calculations indicate that centralization is feasible and cost-effective. Other advantages (e.g. improved quality, higher flexibility) and disadvantages (lack of knowledge of the location and infrastructure) of centralization are discussed. CONCLUSIONS We recommend centralization of telemedical emergency services. However, the number of districts cooperating in one teleemergency doctor office should not be too high and the distance between the ambulance station and the telemedical station should not be too large.

Abstract
Background Over the past decade Smartphone-based activation (SBA) of Community First Responders (CFR) to out-of-hospital cardiac arrests (OHCA) has gained much attention and popularity throughout Europe. Various programmes have been established, and interestingly there are considerable differences in technology, responder spectrum and the degree of integration into the prehospital emergency services. It is unclear whether these dissimilarities affect outcome. This paper reviews the current state in five European countries, reveals similarities and controversies, and presents consensus statements generated in an international conference with the intention to support public decision making on future strategies for SBA of CFR. Methods In a consensus conference a three-step approach was used: (i) presentation of current research from five European countries; (ii) workshops discussing evidence amongst the audience to generate consensus statements; (iii) anonymous real-time voting applying the modified RAND-UCLA Appropriateness method to adopt or reject the statements. The consensus panel aimed to represent all stakeholders involved in this topic. Results While 21 of 25 generated statements gained approval, consensus was only found for 5 of them. One statement was rejected but without consensus. Members of the consensus conference confirmed that CFR save lives. They further acknowledged the crucial role of emergency medical control centres and called for nationwide strategies. Conclusions Members of the consensus conference acknowledged that smartphone-based activation of CFR to OHCA saves lives. The statements generated by the consensus conference may assist the public, healthcare services and governments to utilise these systems to their full potential, and direct the research community towards fields that still need to be addressed.

Abstract
Background: Preoperative anxiety causes profound psychological and physiological reactions that may lead to a worse postoperative recovery, higher intensity of acute and persistent postsurgical pain and impaired quality of life in the postoperative period. Previous randomized controlled trials (RCTs) suggest that auricular acupuncture (AA) is safe and effective in the treatment of preoperative anxiety; however there is a lack of systematic evidence on this topic. Therefore, this protocol was developed following the PRISMA guidelines to adequately evaluate the existing literature regarding the value of AA for the reduction in anxiety in patients in a preoperative setting, compared to other forms of acupuncture, pharmacological, or no control interventions and measured with questionnaires regarding anxiety and fear. Methods: The following databases will be searched: MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ISI Web of Science, and Scopus Database. RCTs will be included if an abstract is available in English. Data collection and analysis will be conducted by two reviewers independently. Quality and risk assessment of included studies will be done using the Cochrane 5.1.0 handbook criteria and meta-analysis of effectiveness and symptom scores will be conducted using the statistical software RevMan V.5.3. Conclusions: This systematic review will evaluate the efficacy and safety of AA for preoperative anxiety. Since all data used in this systematic review and meta-analysis have been published, this review does not require ethical approval. The results may be published in a peer-reviewed journal or be presented in relevant conferences. Registration number: PROSPERO ID CRD42020.

Abstract
OBJECTIVE Auricular stimulation (AS) is a promising method in the treatment of situational anxiety. Expressive writing (EW) is an established psychological method, which reduces test anxiety and improves exam results. The aim of this crossover trial was to compare AS with EW, and with the no intervention (NI) condition, for treatment of exam anxiety. METHODS Healthy medical students underwent 3 comparable anatomy exams with an interval of one month, either performing EW, receiving AS or NI prior to the exam; the order of interventions was randomized. AS was applied using indwelling fixed needles bilaterally at the areas innervated mostly by the auricular branch of the vagal nerve on the day before the exam. Anxiety level, measured using State-Trait-Anxiety Inventory (STAI) before and after the interventions and immediately before exam, was the primary outcome. Quality of night sleep, blood pressure, heart rate and activity of salivary alpha-amylase (sAA) were analyzed across 3 conditions. RESULTS All 37 included participants completed the study. Anxiety level (STAI) decreased immediately after AS in comparison with baseline (P = 0.02) and remained lower in comparison with that after EW and NI (P<0.01) on the day of exam. After EW and NI anxiety increased on the day of exam in comparison with baseline (P<0.01). Quality of sleep improved after AS in comparison with both control conditions (P<0.01). The activity of sAA decreased after EW and after AS (P<0.05) but not after NI condition. CONCLUSION Auricular stimulation, but not expressive writing, reduced exam anxiety and improved quality of sleep in medical students. These changes might be due to reduced activity of the sympathetic nervous system.

Abstract
Zusammenfassung
Zielsetzung In der Notfallversorgung besteht insbesondere in ländlich geprägten Regionen ein Zielkonflikt zwischen hoher Versorgungsqualität und effizientem Mitteleinsatz. Eine mögliche Lösung könnte der Telenotarzt darstellen, der mittels Informations- und Kommunikationstechnologien noch vor Eintreffen des Notarztes oder diesen ersetzend mit der ärztlichen Behandlung beginnen kann.Folgend werden die Kosten eines Telenotarzt-System dargestellt. Die Analyse basiert auf der Einführung eines Telenotarzt-Systems im Landkreis Vorpommern-Greifswald.
Methodik Als Datengrundlage dienten die im Rahmen der Einführung des Telenotarzt-Systems im Landkreis Vorpommern-Greifswald angefallenen Kosten. Sämtliche Kosten wurden zu den Positionen Sach- und immaterielle Investitionen sowie jährliche Betriebs- und Personalkosten zusammengefasst. Weiterhin wurden die Investitionskosten anteilig berücksichtigt, so dass eine Jahresbetrachtung möglich war. Abschließend wurden die Kosten zu einer Kostenfunktion summiert.
Ergebnisse Bei Zusammenführung aller angefallenen Kosten im Rahmen des Projektes Land|Rettung entstehen jährlich für jeden telenotarztfähigen Rettungswagen Kosten in Höhe von 20 842 €. Unter der Annahme eines betriebenen Telenotarzt-Arbeitsplatzes, belaufen sich die jährlichen Sach-, Personal- und Betriebskosten in dem Kreis insgesamt auf 1 049 466 €. Hierin enthalten sind die Investitions- und Betriebskosten des Telenotarzt-Arbeitsplatzes sowie allgemeine Komponenten des Telenotarzt-Systems (beispielsweise Netzwerk und Personalschulungen).
Schlussfolgerung Das Telenotarzt-System, so wie es im Kreis Vorpommern-Greifswald entwickelt wurde, ist grundsätzlich auch für andere ländliche Regionen eine sinnvolle Maßnahme zur Verbesserung der Notfallversorgung. Wie das Beispiel aus Nordostdeutschland zeigt, sind die Kosten jedoch nicht vernachlässigbar. Bei der Übertragung auf andere Regionen können die Kosten abweichen, denn die Größe, der Urbanisierungsgrad sowie die geographische Lage einer Region beeinflussen die Kostenfunktion. Die hier vorgelegte Analyse gibt jedoch einen ersten Ansatz, um diese Kosten abschätzen zu können und damit eine evidenzbasierte Entscheidung über den Einsatz eines Telenotarztes treffen zu können.

Abstract
BACKGROUND German emergency medical services are a 2-tiered system with paramedic-staffed ambulances as the primary response, supported by prehospital emergency doctors for life-threatening conditions. As in all European health care systems, German medical practitioners are in short supply, whereas the demand for timely emergency medical care is constantly growing. In rural areas, this has led to critical delays in the provision of emergency medical care. In particular, in cases of cardiac arrest, time is of the essence because, with each passing minute, the chance of survival with good neurological outcome decreases. OBJECTIVE The project has 4 main objectives: (1) reduce the therapy-free interval through widespread reinforcement of resuscitation skills and motivating the public to provide help (ie, bystander cardiopulmonary resuscitation), (2) provide faster professional first aid in addition to rescue services through alerting trained first aiders by mobile phone, (3) make more emergency physicians available more quickly through introducing the tele-emergency physician system, and (4) enhance emergency care through improving the cooperation between statutory health insurance on-call medical services (German: Kassenärztlicher Bereitschaftsdienst) and emergency medical services. METHODS We will evaluate project implementation in a tripartite prospective and intervention study. First, in medical evaluation, we will assess the influences of various project measures on quality of care using multiple methods. Second, the economic evaluation will mainly focus on the valuation of inputs and outcomes of the different measures while considering various relevant indicators. Third, as part of the work and organizational analysis, we will assess important work- and occupational-related parameters, as well as network and regional indexes. RESULTS We started the project in 2017 and will complete enrollment in 2020. We finished the preanalysis phase in September 2018. CONCLUSIONS Overall, implementation of the project will entail realigning emergency medicine in rural areas and enhancing the quality of medical emergency care in the long term. We expect the project to lead to a measurable increase in medical laypersons' individual motivation to provide resuscitation, to strengthen resuscitation skills, and to result in medical laypersons providing first aid much more frequently. Furthermore, we intend the project to decrease the therapy-free interval in cases of cardiac arrest by dispatching first aiders via mobile phones. Previous projects in urban regions have shown that the tele-emergency physician system can provide a higher availability and quality of emergency call-outs in regular health care. We expect a closer interrelation of emergency practices of statutory health insurance physicians with the rescue service to lead to better coordination of rescue and on-call services.

Evaluating Mechanisms of Postoperative Delirium and Cognitive Dysfunction Following Elective Spine Surgery in Elderly Patients (CONFESS): Protocol for a Prospective Observational Trial. JMIR Res Protoc 2020; 9:e15488. [PMID: 32053113 PMCID: PMC7048391 DOI: 10.2196/15488] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Revised: 10/12/2019] [Accepted: 10/29/2019] [Indexed: 12/12/2022] Open
Abstract
Background Elderly people are at particular high risk for postoperative delirium (POD) following spine surgery, which is associated with longer hospital stays, higher costs, risk for delayed complications, long-term care dependency, and cognitive dysfunction (POCD). It is insufficiently understood which mechanisms and risk factors contribute to the development of POD and POCD following these major but plannable surgeries. Objective This study aims to identify modifiable risk factors in spine surgery. A better understanding thereof would help adapt medical management and surgical strategies to individual risk profiles. Methods This is a single-center observational study jointly conducted by the departments of neurosurgery, neurology, and anesthesiology at a tertiary care hospital in Germany. All patients aged 60 years and older presenting to the neurosurgery outpatient clinic or ward for elective spine surgery are screened for eligibility. Exclusion criteria include presence of neurodegenerative or history of psychiatric disease and medication with significant central nervous system activity (eg, antidepressants, antipsychotics, sedatives). Surgical and anesthetic procedures including duration of surgery as primary end point of this study are thoroughly documented. All patients are furthermore evaluated for their preoperative cognitive abilities by a number of tests, including the Consortium to Establish a Registry for Alzheimer's Disease Plus test battery. Physical, mental, and social health and well-being are assessed using the Patient-Reported Outcome Measurement Information System Profile 29 and Hospital Anxiety and Depression Scale. Patients additionally receive preoperative cerebrovascular ultrasound and structural and functional brain imaging. The immediate postoperative period includes screening for POD using the Nursing Delirium Screening Scale and validation through Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, criteria. We furthermore investigate markers of (neuro)inflammation (eg, interleukins, C-reactive protein, tumor necrosis factor alpha). Preoperative examinations are repeated 3 months postoperatively to investigate the presence of POCD and its mechanisms. Statistical analyses will compare delirious and nondelirious patients for predictors of immediate (POD) and delayed (POCD) cognitive dysfunction. Results This is the first study to prospectively evaluate risk factors for POD and POCD in spine surgery. Recruitment is ongoing, and data collection is estimated to be finished with the inclusion of 200 patients by mid-2020. Conclusions The identification of mechanisms, possibly common, underlying POD and POCD would be a major step toward defining effective interventional strategies early in or even before the postoperative period, including the adaptation of surgical strategies to individual risk profiles.

On-site blood culture incubation shortens the time to knowledge of positivity and microbiological results in septic patients. PLoS One 2019; 14:e0225999. [PMID: 31826003 PMCID: PMC6905563 DOI: 10.1371/journal.pone.0225999] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Accepted: 11/19/2019] [Indexed: 12/29/2022] Open
Abstract
Introduction To determine whether on-site incubation of blood cultures at the intensive care unit (ICU) improves not only the time to incubation but also time to positivity, time to knowledge of positivity and time to results (identification and antibiotic susceptibility testing). Methods This observational single-centre study in ICU patients with severe sepsis and septic shock investigated the impact of blood culture incubation immediately on-site at the ICU (ICU group) by comparison with traditional processing in a remote laboratory (LAB group) on different time intervals of blood culture diagnostics from obtaining blood to clinician notification of final result. The effect of on-site incubation was evaluated in Kaplan-Meier estimates for the time to positivity, time to knowledge of positivity and time to microbiological results and a linear mixed model was built. Results A total of 3,549 blood culture sets from 657 ICU patients were analysed: 2,381 in the LAB group and 1,168 in the ICU group. Overall, 660 (18.6%) blood culture sets were positive and 2,889 (81.4%) sets remained negative. On-site incubation was associated with reduced time to knowledge of positivity (46.9 h [CI 43.4–50.8 h] vs. 28.0 h [CI 23.6–32.2 h], p < 0.001) and reduced time to result (61.4 h [CI 58.4–64.8 h] vs. 42.1 h [CI 39.1–47.5 h], p < 0.001). In blood cultures processed instantaneously at the ICU compared to incubation in the remote laboratory within 4 h, the time to microbiological result was significantly reduced by 8.5 h (p < 0.001). Pre-existing anti-infective therapy had no significant impact on diagnostic time intervals. Conclusions Instantaneous incubation of blood cultures in the ICU compared to incubation in a remote laboratory significantly improves time to knowledge to positivity and time to result. These effects are even more pronounced during off-hours of the microbiological laboratory. The results underline the importance of 24/7 diagnostics to provide round-the-clock processing of blood culture samples in patients with sepsis and septic shock and an immediate to communication of the results to the clinicians.

Abstract
BACKGROUND Transcutaneous vagus nerve stimulation (TVNS) is a promising treatment for acute and chronic pain. However, experimental studies yielded controversial results. We examined if TVNS reduces the perceived intensity of repetitive painful heat stimulation and temporal summation of pain (TSP) in healthy volunteers in comparison with placebo and sham stimulation, as well as no intervention. METHODS In 4 sessions, 90 heat pulse stimuli at individual pain tolerance temperature were applied to the ventral forearm of 49 healthy volunteers (25 women) using a Contact Heat Evoked Potential Stimulator thermode (Medoc, Ramat Yishai, Israel). Pain intensity was assessed with verbal ratings on a numeric pain scale (0-100) at every tenth heat pulse. After the first session in which pain intensities without intervention were evaluated, participants completed 3 sessions in a single-blinded randomized crossover manner: (1) sham stimulation applied at the earlobes, (2) placebo stimulation (inactive device), or (3) TVNS applied at the cymbas conchae. Primary data were analyzed using analysis of variance for repeated measures and t test for paired samples. RESULTS Pain intensity decreased during all interventions as compared to no intervention (ηp = 0.22, P < .001; mean difference TVNS versus no intervention 9.5; 95% confidence interval [CI], 3.6-15.4; P < .001). Hypoalgesic effect of TVNS was better than that of placebo and sham in men before the onset of TSP (mean differences for TVNS versus placebo 6.2; 95% CI, 0.2-12.1; TVNS versus sham 6.2; 95% CI, 0.2-12.1; P < .05). In women, TSP response under TVNS was decreased if compared to no intervention (median difference, 7.5; 95% CI, 3.5-15.0; P = .003). CONCLUSIONS TVNS, placebo, and sham stimulation exerted comparable effects under experimental heat pain stimulation. Only in male participants, TVNS was superior to sham and placebo conditions in the reduction of heat pain before the onset of TSP.

Combination of problem-based learning with high-fidelity simulation in CPR training improves short and long-term CPR skills: a randomised single blinded trial. BMC MEDICAL EDUCATION 2019; 19:180. [PMID: 31151450 PMCID: PMC6544917 DOI: 10.1186/s12909-019-1626-7] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2017] [Accepted: 05/22/2019] [Indexed: 05/05/2023]
Abstract
BACKGROUND Performance of sufficient cardiopulmonary resuscitation (CPR) by medical personnel is critical to improve outcomes during cardiac arrest. It has however been shown that even health care professionals possess a lack of knowledge and skills in CPR performance. The optimal method for teaching CPR remains unclear, and data that compares traditional CPR instructional methods with newer modalities of CPR instruction are needed. We therefore conducted a single blinded, randomised study involving medical students in order to evaluate the short- and long-term effects of a classical CPR education compared with a bilateral approach to CPR training, consisting of problem-based learning (PBL) plus high fidelity simulation. METHODS One hundred twelve medical students were randomized during a curricular anaesthesiology course to a control (n = 54) and an intervention (n = 58) group. All participants were blinded to group assignment and partook in a 30-min-lecture on CPR basics. Subsequently, the control group participated in a 90-min tutor-guided CPR hands-on-training. The intervention group took part in a 45-min theoretical PBL module followed by 45 min of high fidelity simulated CPR training. The rate of participants recognizing clinical cardiac arrest followed by sufficiently performed CPR was the primary outcome parameter of this study. CPR performance was evaluated after the intervention. In addition, a follow-up evaluation was conducted after 6 months. RESULTS 51.9% of the intervention group met the criteria of sufficiently performed CPR as compared to only 12.5% in the control group on the day of the intervention (p = 0.007). Hands-off-time as a marker for CPR continuity was significantly less in the intervention group (24.0%) as compared to the control group (28.3%, p = 0.007, Hedges' g = 1.55). At the six-month follow-up, hands-off-time was still significantly lower in the intervention group (23.7% vs. control group: 31.0%, p = 0.006, Hedges' g = 1.88) but no significant difference in sufficiently performed CPR was detected (intervention group: 71.4% vs. control group: 54.5%, p = 0.55). CONCLUSION PBL combined with high fidelity simulation training leads to a measurable short-term increase in initiating sufficient CPR by medical students immediately after training as compared to classical education. At six month post instruction, these differences remained only partially.

Abstract
Background There is growing evidence that beta-blockade may reduce mortality in selected patients with sepsis. However, it is unclear if a pre-existing, chronic oral beta-blocker therapy should be continued or discontinued during the acute phase of severe sepsis and septic shock. Methods The present secondary analysis of a prospective observational single centre trial compared patient and treatment characteristics, length of stay and mortality rates between adult patients with severe sepsis or septic shock, in whom chronic beta-blocker therapy was continued or discontinued, respectively. The acute phase was defined as the period ranging from two days before to three days after disease onset. Multivariable Cox regression analysis was performed to compare survival outcomes in patients with pre-existing chronic beta-blockade. Results A total of 296 patients with severe sepsis or septic shock and pre-existing, chronic oral beta-blocker therapy were included. Chronic beta-blocker medication was discontinued during the acute phase of sepsis in 129 patients and continued in 167 patients. Continuation of beta-blocker therapy was significantly associated with decreased hospital (P=0.03), 28-day (P=0.04) and 90-day mortality rates (40.7% vs 52.7%; P=0.046) in contrast to beta-blocker cessation. The differences in survival functions were validated by a Log-rank test (P=0.01). Multivariable analysis identified the continuation of chronic beta-blocker therapy as an independent predictor of improved survival rates (HR = 0.67, 95%-CI (0.48, 0.95), P=0.03). Conclusions Continuing pre-existing chronic beta-blockade might be associated with decreased mortality rates up to 90 days in septic patients.

Abstract
Objective Auricular acupuncture (AA) is effective for the treatment of preoperative anxiety. We aimed to study the feasibility and effects of AA on exam anxiety in a prospective observational pilot study. Methods Healthy medical students received bilateral AA using indwelling fixed needles at points MA-IC1, MA-TF1, MA-SC, MA-AH7, and MA-T on the day before an anatomy exam. The needles were removed after the exam. Anxiety levels were measured using the State-Trait-Anxiety Inventory (STAI) and a 100 mm visual analogue scale (VAS-100) before and after the AA intervention and once again immediately before the exam. The duration of sleep on the night before the exam was recorded and compared to that over the preceding 1 week and 6 months (all through students’ recollection). In addition, blood pressure, heart rate and the acceptability of AA to the students were recorded. Results Ten students (all female) were included in the final analysis. All tolerated the needles well and stated they would wish to receive AA again for exam anxiety in the future. Exam anxiety measured using both STAI and VAS-100 decreased by almost 20% after AA. Conclusions AA was well accepted, the outcome measurement was feasible, and the results have facilitated the calculation of the sample size for a subsequent randomised controlled trial.

Abstract
Objective: The detection of auricular acupuncture (AA) points by measuring electrical skin resistance (ESR) is often used in diagnostics and therapy; however, systematic investigations of ESR in AA points are rare. The aim of this study was to examine the frequency of detection of AA points with reduced ESR in patients scheduled for unilateral hip arthroplasty. Materials and Methods: Data were obtained from 2 prospective clinical trials, which studied the perioperative analgesic effects of AA in patients with unilateral degenerative hip osteoarthritis. Three AA points (MA-TF1, MA-AH4, and MA-IC1) were examined in these patients before arthroplasty surgery using a SVESA (Neuralstift SVESA 1070, SVESA, Muenchen, Germany) neural pen. The frequency of AA points detection on the ipsi- and contralateral sides of the affected hip joint was registered and analyzed with a χ2 test. Results: The data of 114 patients (60 females) were available for analysis. AA points with lower ESR were detected more frequently on the side ipsilateral to the affected joint rather than on the contralateral side: 81% versus 37% of patients (P < 0.0001). None of the AA points could be identified at all in 13% of patients with diabetes mellitus versus 3% of patients without diabetes mellitus (P = 0.07). Conclusions: AA points with low ESR were detected more frequently on the side ipsilateral to the underlying pathology. This finding is in agreement with neurophysiologic data. The therapeutic value of this finding should be clarified in future studies.

Medical Correctness and User Friendliness of Available Apps for Cardiopulmonary Resuscitation: Systematic Search Combined With Guideline Adherence and Usability Evaluation. JMIR Mhealth Uhealth 2018; 6:e190.

Abstract
Background In case of a cardiac arrest, start of cardiopulmonary resuscitation by a bystander before the arrival of the emergency personnel increases the probability of survival. However, the steps of high-quality resuscitation are not known by every bystander or might be forgotten in this complex and time-critical situation. Mobile phone apps offering real-time step-by-step instructions might be a valuable source of information. Objective The aim of this study was to examine mobile phone apps offering real-time instructions in German or English in case of a cardiac arrest, to evaluate their adherence to current resuscitation guidelines, and to test their usability. Methods Our 3-step approach combines a systematic review of currently available apps guiding a medical layperson through a resuscitation situation, an adherence testing to medical guidelines, and a usability evaluation of the determined apps. The systematic review followed an adapted preferred reporting items for systematic reviews and meta-analyses flow diagram, the guideline adherence was tested by applying a conformity checklist, and the usability was evaluated by a group of mobile phone frequent users and emergency physicians with the system usability scale (SUS) tool. Results The structured search in Google Play Store and Apple App Store resulted in 3890 hits. After removing redundant ones, 2640 hits were checked for fulfilling the inclusion criteria. As a result, 34 apps meeting all inclusion criteria were identified. These included apps were analyzed to determine medical accuracy as defined by the European Resuscitation Council’s guidelines. Only 5 out of 34 apps (15%, 5/34) fulfilled all criteria chosen to determine guideline adherence. All other apps provided no or wrong information on at least one relevant topic. The usability of 3 apps was evaluated by 10 mobile phone frequent users and 9 emergency physicians. Of these 3 apps, solely the app “HELP Notfall” (median=87.5) was ranked with an SUS score above the published average of 68. This app was rated significantly superior to “HAMBURG SCHOCKT” (median=55; asymptotic Wilcoxon test: z=−3.63, P<.01, n=19) and “Mein DRK” (median=32.5; asymptotic Wilcoxon test: z=−3.83, P<.01, n=19). Conclusions Implementing a systematic quality control for health-related apps should be enforced to ensure that all products provide medically accurate content and sufficient usability in complex situations. This is of exceptional importance for apps dealing with the treatment of life-threatening events such as cardiac arrest.

Abstract
OBJECTIVE Auricular acupuncture (AA) is a promising alternative treatment for situational anxiety. The aim of this pilot investigation was to test the acceptability and feasibility of AA as a treatment for preoperative anxiety (PA) in preparation for a subsequent randomised controlled trial. METHODS AA was offered for treatment of PA to female patients who were scheduled for ambulatory gynaecological surgery. In patients who agreed, indwelling fixed needles were applied bilaterally at the points MA-IC1, MA-TF1, MA-SC, MA-AH7 and MA-T the day before surgery. Patients who declined AA but agreed to be examined constituted the control group (no intervention). State anxiety (primary outcome) was measured using the State-Trait-Anxiety Inventory (STAI) before AA (time I), the evening before surgery (time II) and immediately before surgery (time III). Anxiety was measured with a 100 mm visual analogue scale (VAS-100); heart rate, blood pressure and serum cortisol were also quantified. RESULTS Data from 62 patients (32 with AA and 30 with no intervention) were analysed. Whereas preoperative anxiety was reduced after AA the evening before surgery (P<0.01), anxiety levels in the control group increased from the first to the last measurement (P<0.001). Secondary outcomes were comparable between the patients from both groups. CONCLUSIONS AA was acceptable and feasible as a treatment for preoperative anxiety. The results were used for the sample size calculation of a subsequent randomised controlled clinical trial. TRIAL REGISTRATION NUMBER NCT02656966; Results.

Abstract
BACKGROUND The management of postoperative pain and recovery is still unsatisfactory in a number of cases in clinical practice. Opioids used for postoperative analgesia are frequently associated with adverse effects, including nausea and constipation, preventing smooth postoperative recovery. Not all patients are suitable for, and benefit from, epidural analgesia that is used to improve postoperative recovery. The non-opioid, lidocaine, was investigated in several studies for its use in multimodal management strategies to reduce postoperative pain and enhance recovery. This review was published in 2015 and updated in January 2017. OBJECTIVES To assess the effects (benefits and risks) of perioperative intravenous (IV) lidocaine infusion compared to placebo/no treatment or compared to epidural analgesia on postoperative pain and recovery in adults undergoing various surgical procedures. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, CINAHL, and reference lists of articles in January 2017. We searched one trial registry contacted researchers in the field, and handsearched journals and congress proceedings. We updated this search in February 2018, but have not yet incorporated these results into the review. SELECTION CRITERIA We included randomized controlled trials comparing the effect of continuous perioperative IV lidocaine infusion either with placebo, or no treatment, or with thoracic epidural analgesia (TEA) in adults undergoing elective or urgent surgery under general anaesthesia. The IV lidocaine infusion must have been started intraoperatively, prior to incision, and continued at least until the end of surgery. DATA COLLECTION AND ANALYSIS We used Cochrane's standard methodological procedures. Our primary outcomes were: pain score at rest; gastrointestinal recovery and adverse events. Secondary outcomes included: postoperative nausea and postoperative opioid consumption. We used GRADE to assess the quality of evidence for each outcome. MAIN RESULTS We included 23 new trials in the update. In total, the review included 68 trials (4525 randomized participants). Two trials compared IV lidocaine with TEA. In all remaining trials, placebo or no treatment was used as a comparator. Trials involved participants undergoing open abdominal (22), laparoscopic abdominal (20), or various other surgical procedures (26). The application scheme of systemic lidocaine strongly varies between the studies related to both dose (1 mg/kg/h to 5 mg/kg/h) and termination of the infusion (from the end of surgery until several days after).The risk of bias was low with respect to selection bias (random sequence generation), performance bias, attrition bias, and detection bias in more than 50% of the included studies. For allocation concealment and selective reporting, the quality assessment yielded low risk of bias for only approximately 20% of the included studies.IV Lidocaine compared to placebo or no treatment We are uncertain whether IV lidocaine improves postoperative pain compared to placebo or no treatment at early time points (1 to 4 hours) (standardized mean difference (SMD) -0.50, 95% confidence interval (CI) -0.72 to -0.28; 29 studies, 1656 participants; very low-quality evidence) after surgery. Due to variation in the standard deviation (SD) in the studies, this would equate to an average pain reduction of between 0.37 cm and 2.48 cm on a 0 to 10 cm visual analogue scale . Assuming approximately 1 cm on a 0 to 10 cm pain scale is clinically meaningful, we ruled out a clinically relevant reduction in pain with lidocaine at intermediate (24 hours) (SMD -0.14, 95% CI -0.25 to -0.04; 33 studies, 1847 participants; moderate-quality evidence), and at late time points (48 hours) (SMD -0.11, 95% CI -0.25 to 0.04; 24 studies, 1404 participants; moderate-quality evidence). Due to variation in the SD in the studies, this would equate to an average pain reduction of between 0.10 cm to 0.48 cm at 24 hours and 0.08 cm to 0.42 cm at 48 hours. In contrast to the original review in 2015, we did not find any significant subgroup differences for different surgical procedures.We are uncertain whether lidocaine reduces the risk of ileus (risk ratio (RR) 0.37, 95% CI 0.15 to 0.87; 4 studies, 273 participants), time to first defaecation/bowel movement (mean difference (MD) -7.92 hours, 95% CI -12.71 to -3.13; 12 studies, 684 participants), risk of postoperative nausea (overall, i.e. 0 up to 72 hours) (RR 0.78, 95% CI 0.67 to 0.91; 35 studies, 1903 participants), and opioid consumption (overall) (MD -4.52 mg morphine equivalents , 95% CI -6.25 to -2.79; 40 studies, 2201 participants); quality of evidence was very low for all these outcomes.The effect of IV lidocaine on adverse effects compared to placebo treatment is uncertain, as only a small number of studies systematically analysed the occurrence of adverse effects (very low-quality evidence).IV Lidocaine compared to TEAThe effects of IV lidocaine compared with TEA are unclear (pain at 24 hours (MD 1.51, 95% CI -0.29 to 3.32; 2 studies, 102 participants), pain at 48 hours (MD 0.98, 95% CI -1.19 to 3.16; 2 studies, 102 participants), time to first bowel movement (MD -1.66, 95% CI -10.88 to 7.56; 2 studies, 102 participants); all very low-quality evidence). The risk for ileus and for postoperative nausea (overall) is also unclear, as only one small trial assessed these outcomes (very low-quality evidence). No trial assessed the outcomes, 'pain at early time points' and 'opioid consumption (overall)'. The effect of IV lidocaine on adverse effects compared to TEA is uncertain (very low-quality evidence). AUTHORS' CONCLUSIONS We are uncertain whether IV perioperative lidocaine, when compared to placebo or no treatment, has a beneficial impact on pain scores in the early postoperative phase, and on gastrointestinal recovery, postoperative nausea, and opioid consumption. The quality of evidence was limited due to inconsistency, imprecision, and study quality. Lidocaine probably has no clinically relevant effect on pain scores later than 24 hours. Few studies have systematically assessed the incidence of adverse effects. There is a lack of evidence about the effects of IV lidocaine compared with epidural anaesthesia in terms of the optimal dose and timing (including the duration) of the administration. We identified three ongoing studies, and 18 studies are awaiting classification; the results of the review may change when these studies are published and included in the review.

Impact of antibiotic administration on blood culture positivity at the beginning of sepsis: a prospective clinical cohort study. Clin Microbiol Infect 2018; 25:326-331. [PMID: 29879482 DOI: 10.1016/j.cmi.2018.05.016] [Citation(s) in RCA: 111] [Impact Index Per Article: 18.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2018] [Revised: 05/09/2018] [Accepted: 05/12/2018] [Indexed: 01/21/2023]
Abstract
OBJECTIVES Sepsis guidelines recommend obtaining blood cultures before starting anti-infective therapy in patients with sepsis. However, little is known of how antibiotic treatment before sampling affects bacterial growth. The aim of this study was to compare the results of blood cultures drawn before and during antibiotic therapy. METHODS Prospective clinical cohort study of septic patients. Adult intensive care unit patients with two or three blood culture sets at the beginning of sepsis between 2010 and 2017 were included. Patients with blood culture samples obtained before antibiotic therapy were compared with patients with samples taken during antibiotic therapy. Blood culture positivity, defined as presence of a microbiological pathogen, was compared between the groups. Logistic regression was performed to adjust the impact of different factors with respect to blood culture positivity. RESULTS In total, 559 patients with 1364 blood culture sets at the beginning of sepsis were analysed. Blood culture positivity was 50.6% (78/154) among patients with sepsis who did not receive antibiotics and only 27.7% (112/405) in those who were already receiving antibiotics (p <0.001). Logistic regression revealed antibiotic therapy as an independent factor for less pathogen identification (odds ratio 0.4; 95% CI 0.3-0.6). Gram-positive pathogens (28.3% (111/392) versus 11.9% (116/972); p <0.001) and also Gram-negative pathogens (16.3% (64/392) versus 9.3% (90/972); p <0.001) were more frequent in blood culture sets drawn before antibiotic therapy compared with sets obtained during antibiotic therapy. CONCLUSIONS Obtaining blood cultures during antibiotic therapy is associated with a significant loss of pathogen detection. This strongly emphasizes the current recommendation to obtain blood cultures before antibiotic administration in patients with sepsis.

[Sepsis detection in emergency medicine : Results of an interprofessional survey on sepsis detection in prehospital emergency medicine and emergency departments]. Anaesthesist 2018; 67:584-591. [PMID: 29802441 DOI: 10.1007/s00101-018-0456-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 04/16/2018] [Accepted: 04/27/2018] [Indexed: 11/30/2022]
Abstract
BACKGROUND Sepsis is associated with a high mortality, which can be reduced by starting screening, diagnostics and treatment as early as possible. Due to multiple educational programs and increased awareness, a decreased sepsis mortality on intensive care units has been achieved. Many patients with sepsis are admitted by the prehospital emergency service to hospital emergency departments. Thus, prehospital emergency services and emergency departments provide an opportunity to start screening, diagnosis and treatment earlier. OBJECTIVES To detect sepsis it is paramount that emergency personnel are aware of the disease and have a profound knowledge regarding symptoms, screening and diagnostics. The objective of this survey was to examine the state of knowledge regarding sepsis among staff working in emergency medicine. MATERIAL AND METHODS To assess the awareness and knowledge, a paper-based, anonymous survey was conducted among prehospital and emergency department personnel from May to August 2017 in northeastern Germany. Testing of significance was carried out using the χ2-testand Fisher's exact test. RESULTS Out of 411 persons polled 212 answered (response rate 51.6%) and 24 questionnaires were incomplete and thus excluded. A total of 188 questionnaires were included covering 55 emergency physicians, 23 nurses, 82 paramedics and 19 emergency dispatchers. On a 4-point Likert scale 100% of emergency doctors, 96% of nurses, 84% of paramedics and 84% of emergency dispatchers considered early initiation of sepsis treatment to be important. Additionally, 92% of emergency physicians and 65% of nurses had attended educational programs on sepsis within the last year, which is significantly higher than among paramedics (19%, p < 0.01) and emergency dispatchers (21%, p = 0.025). In addition, 38% of paramedics and 47% of emergency dispatchers had never attended lectures on sepsis. The quick sequential (sepsis-related) organ failure assessment (qSOFA) was known by 80% of emergency doctors, thus, significantly more often than by nurses (26%), paramedics (29%) and emergency dispatchers (29%, p < 0.01). The emergency personnel were asked to tick all symptoms they associated with sepsis from a display of 14 symptoms. Among all occupation groups the majority selected "increased body temperature", "drop in blood pressure" and "altered breathing". In relation to "increased body temperature" the symptom "altered mental status" was selected significantly more frequently by emergency doctors than by nurses and paramedics (p = 0.02 and p < 0.01, respectively). The combination of at least all 3 qSOFA parameters was selected significantly more often by emergency doctors (62%) than by nurses (13%) and paramedics (10%, p = 0.017 and p < 0.01, respectively). CONCLUSION Although emergency personnel rated an early initiation of sepsis treatment as important, sepsis knowledge was limited. While the majority of emergency doctors and many nurses had attended educational programs on sepsis within the last year, an alarmingly high percentage of paramedics and emergency dispatchers had never received sepsis education. Emergency personnel are mostly unfamiliar with the qSOFA score and did not associate an altered mental status with sepsis. In light of the high sepsis morbidity and mortality, further achievements might be made by initiating sepsis screening and diagnostics in the prehospital setting. Analogous to advancements in intensive care units, increased educational programs for emergency personnel might lead to an earlier detection and improved prognosis of sepsis.

Bystander-witnessed cardiac arrest is associated with reported agonal breathing and leads to less frequent bystander CPR. Resuscitation 2018; 127:114-118. [PMID: 29679693 DOI: 10.1016/j.resuscitation.2018.04.017] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 03/24/2018] [Accepted: 04/14/2018] [Indexed: 11/24/2022]
Abstract
AIM Although the importance of bystander cardiopulmonary resuscitation has been shown in multiple studies, the rate of bystander cardiopulmonary resuscitation is still relatively low in many countries. Little is known on bystanders' perceptions influencing the decision to start cardiopulmonary resuscitation. Our study aims to determine such factors. MATERIALS AND METHODS Semi-structured telephone interviews with bystanders of out-of-hospital cardiac arrests between December 2014 and April 2016 were performed in a prospective manner. This single-center survey was conducted in the city of Münster, Germany. The bystander's sex and age, the perception of the victim's breathing and initial condition were correlated with the share of bystander cardiopulmonary resuscitation in the corresponding group. RESULTS 101 telephone interviews were performed with 57 male and 44 female participants showing a mean age of 52.7 (SD ± 16.3). In case of apnoea 38 out of 46 bystanders (82.6%) started cardiopulmonary resuscitation; while in case of descriptions indicating agonal breathing 19 out of 35 bystanders (54.3%) started cardiopulmonary resuscitation (p = .007). If the patient was found unconscious 47 out of 63 bystanders (74.7%) performed cardiopulmonary resuscitation, while in cases of witnessed cardiac arrest 19 out of 38 bystanders (50%) attempted cardiopulmonary resuscitation (p = .012). Witnessed change of consciousness is an independent factor significantly lowering the probability of starting cardiopulmonary resuscitation (regression coefficient -1.489, p < .05). CONCLUSION The witnessed loss of consciousness was independently associated with a significant reduction in the likelihood that bystander-CPR was started. These data reinforce the importance of teaching the recognition of early cardiac arrest.

Integrating cross-border emergency medicine systems: Securing future preclinical medical workforce for remote medical services. Best Pract Res Clin Anaesthesiol 2018; 32:39-46.

Abstract
The European Union intends to enable its citizens to interact across borders in relevant areas of society and culture to further integrate neighboring regions. Medicine has not been at the core of recent EU-funded efforts in central Europe, partially due to significant differences in health care administration, delivery, reimbursement, and culture. However, impeding changes in social structure and centralization of specialized care warrant changes in preclinical administration of medical care, which are already transforming practices across developed countries in central Europe. Moreover, demographic and social changes are transforming not only patients but also health care providers, thus leading to an increased need for specialized medical personnel, particularly in regions close to formerly secluding borders. The EU-funded cooperation project presented in this article is located in the Euroregion Pomerania, which consists of northeastern Germany and northwestern Poland. This project emerged because of the need to solve practical emergency medicine-related problems for many years, which brought partners together. Unfortunately, administrative and medical interaction has not become significantly easier with Poland joining the Schengen area in 2007 and, subsequently, initial international contracts regarding, among other things, emergency medicine being negotiated and signed thereafter. Three different interdependent areas of cooperation within the project deal with key aspects of an improved and eventually integrated cooperation. An accepted clarification of administrative and legal foundations - or the lack and thus the need thereof - needs to be defined. Specialized language and simulation-based education and practice sessions employing modern technology throughout will be introduced to the entire region. Finally, the pre-existing and developing acceptance and sustainability aspects of personnel involved in the aforementioned actions and stakeholders on both sides of the border will be evaluated. In essence, the project focuses on a multimodal improvement of professional cooperation of key providers of emergency medicine services in the Euroregion Pomerania. Thereby, it aims to improve infrastructure; interpersonal and professional skills of involved personnel, administrative, and cultural relations; and eventually identification of specialized personnel with their workplace and region to secure and retain important medical workforce in an otherwise remote area on both sides of a formerly secluded border.
