Challenges and best practices of dispatcher-assisted cardiopulmonary resuscitation: A scoping review protocol.

Introduction: Improved survival from out-of-hospital cardiac arrest with good neurological outcome was observed in association with dispatcher-assisted cardiopulmonary resuscitation, increasing the number of bystander-initiated resuscitations and minimizing the no-flow time in the first minutes of cardiac arrest. Objective: The objective of this scoping review is to map and summarise the existing literature on dispatcher-assisted cardiopulmonary resuscitation, focusing on reported experiences, challenges, and best practices, highlighting strategies that could improve the provision of cardiopulmonary resuscitation instructions to bystanders during out-of-hospital cardiac arrest. Inclusion criteria: Studies related to dispatcher-assisted cardiopulmonary resuscitation, involving human subjects, with an English abstract. The concept of interest is focused on the methods of provision of dispatcher-assisted cardiopulmonary resuscitation analysing specific experiences of implementation, challenges, and best practices, and can be generalized to any country; cultural factors, geographic features, and specific racial or gender-based differences will be analysed and discussed. Methods: Four databases (PubMed, Embase, Cumulative Index to Nursing & Allied Health Literature, and the Cochrane Library) will be searched for studies published from 2018 to 2023. All study designs, including experimental and observational studies, will be assessed for inclusion. Titles and abstracts of identified citations will be screened for inclusion; subsequently, full texts of potentially relevant sources will be assessed for inclusion by two reviewers. Any disagreements between the reviewers will be resolved through discussion. Relevant grey literature (conference proceedings, government documents, and theses) will be analysed and included. Data will be extracted in a standardized form, following Joanna Briggs Institute recommendations. Results will be synthesized and reported using a narrative approach, categorising findings into themes related to the effectiveness of dispatcher-assisted cardiopulmonary resuscitation, challenges, and best practices.

Insertion Site Dilemma: Rethinking Radial Arterial Catheter Placement for Device Resilience.

The study by Marie et al (2023) discusses their outcomes regarding the distance of radial arterial catheters from the radiocarpal joint and its association to device failure, although authors found no significant difference in failure rates between catheters inserted proximally or distally to the radiocarpal joint. However, other recent studies have reported that catheters inserted more distally are more likely to fail, with rates high as 25%. Factors that contribute to failure include poor site selection, infection, device occlusion, or dislodgement. With reliance on accurate hemodynamics from arterial catheters, providers should be aware of the risks and take steps to minimize them, as catheter failure is more than just associated infection, the inability to aspirate blood or a useable arterial waveform. Optimal insertion location, use of ultrasound-guided techniques, appropriate securement, and close monitoring of the catheter, along with accurate reporting of failure reasons, will help clarify future research outcomes.

Mass Casualty Incident Preparedness for Airport Emergencies: Report From an Aeroplane Crash Simulation at Guglielmo Marconi Airport, Bologna (Italy).

BACKGROUND: Airport emergencies are rare but potentially catastrophic; therefore, system preparedness is crucial. Airport emergency plans include the organization of emergency drills on a regular basis, including full-scale exercises, to train and test the entire rescue organization. OBJECTIVE: This report describes a full-scale simulation at Bologna International Airport, Italy, in October 2022, involving local EMS resources. METHODS: A full-scale aeroplane crash was simulated on the airport ground, activating the Airport emergency plan, and requiring the intervention of supplementary resources (ambulances, medical cars, and other emergency vehicles). RESULTS: Twenty-seven simulated patients were evaluated by EMS: START triage assessment was correct for 81.48% of patients; 11.11% were over-triaged and 7.41% were under-triaged. All patients were transported to the hospitals of the area. The simulation ended 2 hours and 28 minutes after the initial alarm. CONCLUSION: The response time proved a good response. Triage accuracy was correct in more than 80% of simulated patients. The availability of a trauma centre within 6 kilometres allowed the transportation of a quota of patients directly from the event, without affecting transportation times. Areas for improvement were identified in the communication within the different agencies and in moving ambulances within the airport runway without airport personnel guidance.

Empowering the next Generation: An innovative "Kids Save Lives" blended learning programme for schoolchildren training.

INTRODUCTION: Guidelines recommend teaching resuscitation from school age; however, little is known about the best methods to provide it. We devised a blended learning program for primary and secondary students (Kids Save Lives - KSL) consisting of brief lectures, practical training with mannequins, and virtual reality. We aimed to evaluate its impact on students' attitudes towards intervening during cardiac arrest and their knowledge about basic life support. METHODS: This observational, prospective, before-and-after study assessed attitudes and basic life support knowledge in primary and secondary school children exposed to the KSL program. 20 events were conducted in the metropolitan area of Bologna, Italy. A multiple-choice test (before and after the course) explored attitude, knowledge and perceptions of realism, engagement, and agreement with the virtual reality method. RESULTS: A total of 1,179 students (response rate 81.4%) were included in the final analysis, with 12.89% from primary schools, 5.94% from middle schools, and 81.17% from high schools. Students' willingness to intervene during a cardiac arrest rose from 56.9% to 93.1% (p < 0.001) post-course. The course's realism, engagement, and future prospects received positive feedback, with median scores notably higher in primary schools compared to secondary schools. CONCLUSION: The blended learning method improved students' understanding of basic life support techniques and their attitude to act during cardiac arrest situations. The positive reception of the virtual reality component underscores technology's potential to bolster engagement and should be further explored for basic life support teaching in schoolchildren.

Moral injury in a global health emergency: a validation study of the Italian version of the Moral Injury Events Scale adjusted to the healthcare setting.

Background: When exposed to events that transgress one's moral beliefs, a plethora of negative consequences may follow, which are captured by the concept of moral injury (MI). Despite its relevance to experiences of healthcare workers during a global health emergency, there is lack of validated MI instruments adapted to the healthcare setting.Objective: The present study aims to provide a validation of the Italian version of the Moral Injury Events Scale (MIES) adjusted to the healthcare setting by assessing its factor structure, internal consistency and construct validity.Methods: A sample of 794 healthcare workers (46% nurses, 51% female) engaged in hospital facilities during the COVID-19 pandemic in Italy completed measures of MI, PTSD, anxiety, depression, burnout, meaning in life and positive affect.Results: Using an exploratory structural equation modelling (ESEM) we assessed the scale factor structure for the entire sample and separately for nurse professional and female healthcare worker groups. Findings support a three-factor solution: Factor 1 'perceived transgressions by others'; Factor 2 'perceived transgressions by self'; and Factor 3 'perceived betrayals by others'. Findings also indicate some level of convergence with measures of PTSD, anxiety, depression and burnout.Conclusion: Results suggest that the MIES may be useful in capturing unique experiences of moral injury amongst healthcare workers engaged in a global health emergency. The low range correlations with measures of psychological distress might potentially indicate that MI, which captures cognitive value judgements rather than manifest symptomatology, may uniquely explain a certain amount of variance. Implications for the development of new empirically derived and theoretical guided tools are discussed, highlighting the need for future research to examine the role of individualising and social binding moral principles in gaining a more nuanced understanding of moral injury experiences amongst healthcare professionals across different socio-cultural settings.

The Italian validation of the MIES adapted to the healthcare setting yielded a three-factor structure: (a) 'perceived transgressions by self'; (b) 'perceived transgressions by others'; (c) 'perceived betrayals by others'.Findings suggest that the MIES may be useful in capturing unique experiences of moral injury amongst healthcare workers engaged in a global health emergency.Future research should consider the role of individualising and social binding moral principles in shaping moral injury experiences among healthcare professionals across different socio-cultural settings.

Relationship between noise levels and intensive care patients' clinical complexity: An observational simulation study.

BACKGROUND: Noise pollution in intensive care units is a relevant problem, associated with psychological and physiological consequences for patients and healthcare staff. Sources of noise pollution include medical equipment, alarms, communication tools, staff activities, and conversations. AIM: To explore the cumulative effects of noise caused by an increasing number and type of medical devices in an intensive care setting on simulated patients with increasing clinical complexity. Secondly, to measure medical device alarms and nursing activities' sound levels, evaluating their role as potentially disruptive noises. STUDY DESIGN: Observational simulation study (reported according to the STROBE checklist). Using an electronic sound meter, the sound levels of an intensive care room in seven simulated clinical scenarios were measured on a single day (09 March 2022), each featuring increasing numbers of devices, hypothetically corresponding to augmented patients' clinical complexity. Secondly, noise levels of medical device alarms and specific nursing activities performed at a distance of three meters from the sound meter were analysed. RESULTS: The empty room's mean baseline noise level was 37.8 (±0.7) dBA; among the simulated scenarios, noise ranged between 45.3 (±1.0) and 53.5 (±1.5) dBA. Alarms ranged between 76.4 and 81.3 dBA, while nursing tasks (closing a drawer, opening a saline bag overwrap, or sterile packages) and speaking were all over 80 dBA. The noisiest activity was opening a sterile package (98 dBA). CONCLUSION: An increased number of medical devices, an expression of patients' higher clinical complexity, is not a significant cause of increased noise. Some specific nursing activities and conversations produce higher noise levels than medical devices and alarms. This study's findings suggest further research to assess the relationships between these factors and to encourage adequate noise reduction strategies. RELEVANCE TO CLINICAL PRACTICE: Excessive noise level in the intensive care unit is a clinical issue that negatively affects patients' and healthcare providers' well-being. The increase in baseline room noise from medical devices is generally limited. Typical nursing tasks and conversations produce higher noise levels than medical devices and alarms. These findings could be helpful to raise awareness among healthcare professionals to recognize noise sources. The noisiest components of the environment can be modified by staff behaviour, promoting noise reduction strategies and improving the critical care environment.

Safe Insertion of Arterial Catheters (SIA): An ultrasound-guided protocol to minimize complications for arterial cannulation.

Direct puncture and cannulation of peripheral arteries is frequently performed in critical care and in emergency settings, mainly for hemodynamic monitoring and blood sampling. While there is abundant literature on peripheral arterial cannulation in children and adults, there is still scope for clinical improvements which may impact on patient safety. Although the radial artery is the most frequently utilized access site today, due to its superficial proximity, ease of access, and low risk of adverse events, other sites are sometimes chosen. The authors propose the Safe Insertion of Arterial Catheters (SIA) protocol, an ultrasound-guided insertion bundle applying a systematic approach to arterial cannulation, with a focus on improving insertion practices, reducing procedural complications, increasing the patient safety profile, and improving device performance.

Non-Invasive Ventilation in the Prehospital Emergency Setting: A Systematic Review and Meta-Analysis.

INTRODUCTION: Noninvasive ventilation is a well-established treatment for acute respiratory failure, being increasingly applied in the prehospital setting. This systematic review and meta-analysis aims to investigate whether early prehospital initiation of noninvasive ventilation reduces mortality compared to standard oxygen therapy. METHODS: We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials from inception to February 7th, 2022, for studies comparing prehospital noninvasive ventilation performed by emergency medical services versus standard oxygen therapy in patients with acute respiratory failure. The primary outcome was mortality at the longest follow-up available. RESULTS: We included ten randomized studies and two quasi-randomized studies for a total of 1485 patients. Prehospital treatment with noninvasive ventilation compared with standard oxygen therapy did not significantly reduce mortality at the longest follow-up available (107/810 [13%] vs 114/772 [15%]; RR = 0.89; 95% CI, 0.70-1.13; P = 0.34; I2=24%). The endotracheal intubation rate was reduced when receiving prehospital noninvasive ventilation (38/776 [4.9%] vs 81/743 [11%]; RR = 0.44; 95% CI, 0.31-0.63; P < 0.001; I2=0%; number needed to treat 17). The intensive care admission rate (114/532 [21%] vs 129/507 [25%]; RR = 0.85; 95% CI, 0.69-1.04; P = 0.11; I2=0%) and length of hospital stay (mean difference=-1.29 days; 95% CI, -3.35-0.77; P = 0.21; I2=82%) were similar between groups. CONCLUSIONS: Adults with acute respiratory failure treated in the prehospital setting with noninvasive ventilation had a lower risk of intubation than those managed with standard oxygen therapy, with similar risk of death, intensive care admission, and length of hospital stay.

Incidence, characteristics, and outcome of out-of-hospital cardiac arrest in Italy: A systematic review and meta-analysis.

Introduction: Data on out-of-hospital cardiac arrest (OHCA) is limited in Italy, and there has never been a comprehensive systematic appraisal of the available evidence. Therefore, this review aims to explore the incidence, characteristics, and outcome of OHCA in Italy. Methods: We systematically searched PubMed, Embase, Google Scholar, ResearchGate, and conference proceedings up to September 23, 2022. Studies investigating OHCA in Italy and reporting at least one outcome related to cardiac arrest were considered eligible. The primary outcome was survival at the longest follow-up available. Risk of bias was assessed using the Joanna Briggs Institute critical appraisal tool. A random-effects model proportion meta-analysis was performed to calculate the pooled outcomes with 95% confidence interval (CI). Results: We included 42 studies (43,042 patients) from 13 of the 20 Italian regions published between 1995 and 2022. Only five studies were deemed to be at low risk of bias. The overall average incidences of OHCA attended by emergency medical services and with resuscitation attempted were 86 (range: 10-190) and 55 (range: 6-108) per 100,000 populations per year, respectively. Survival at the longest follow-up available was 9.0% (95% CI, 6.7-12%; 30 studies and 15,195 patients) in the overall population, 25% (95% CI, 21-30%; 16 studies and 2,863 patients) among patients with shockable rhythms, 28% (95% CI, 20-37%; 8 studies and 1,292 patients) among the Utstein comparator group. Favourable neurological outcome was 5.0% (95% CI, 3.6-6.6%; 16 studies and 9,675 patients). Return of spontaneous circulation was achieved in 19% (95% CI, 16-23%; 40 studies and 30,875 patients) of cases. Bystanders initiated cardiopulmonary resuscitation in 26% (95% CI, 21-32%; 33 studies and 23,491 patients) of cases but only in 3.2% (95% CI, 1.9-4.9%; 9 studies and 8,508 patients) with an automated external defibrillator. The mean response time was 10.2 (95% CI, 8.9-11.4; 25 studies and 23,997 patients) minutes. Conclusions: Survival after OHCA in Italy occurred in one of every ten patients. Bystanders initiated cardiopulmonary resuscitation in only one-third of cases, rarely with a defibrillator. Different areas of the country collected data, but an essential part of the population was not included. There was high heterogeneity and large variation in outcomes results and reporting, limiting the confidence in the estimates of incidence and outcome. Creating and maintaining a nationwide registry is a priority.

The Effect of Intensive Care Unit Diaries on Posttraumatic Stress Disorder, Anxiety, and Depression: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

INTRODUCTION: Patients discharged from the intensive care unit (ICU) suffer from long-term symptoms affecting the physical, psychological, and cognitive well-being and cannot understand memories and dreams. Intensive care unit diaries describe daily events about the patient and may allow them to reconstruct their experience. OBJECTIVE: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the effects of ICU diaries on posttraumatic stress disorder (PTSD), depression, and anxiety. METHODS: Five electronic databases were searched up to May 6, 2022. We included RCTs comparing patients admitted to the ICU who received a diary to those who did not receive a diary. The primary outcome was the rate of PTSD. Secondary outcomes were rates of depression and anxiety. RESULTS: We included 7 RCTs. Patients who received a diary during the ICU admission had reduced rate of PTSD (78/432 [18%] vs 106/422 [25%]; risk ratio [RR], 0.73; 95% confidence interval [CI], 0.57-0.94; P = .02; I2 = 0%; trial sequential analysis-adjusted CI, 0.55-0.97) when compared with patients who did not receive a diary. We found a non-statistically significant difference toward a reduction in the rate of depression (38/232 [16%] vs 54/224 [24%]; RR, 0.70; 95% CI, 0.49-1.01; P = .06; I2 = 0%) and anxiety (63/232 [27%] vs 70/224 [31%]; RR, 0.64; 95% CI, 0.29-1.40; P = .26; I2 = 67%). CONCLUSIONS: Providing an ICU diary to patients admitted to the ICU reduced the rate of PTSD symptoms compared with usual care.

10 best practice tips with radial arterial catheterization.

Radial arterial catheters (RAC) are used extensively across critical care settings (Anesthesia, Intensive Care, Emergency Medicine) for continuous hemodynamic monitoring, allowing for immediate adjustments in vasopressor therapies and blood collection. Radial catheter failures are an ongoing significant issue for critical care clinicians with reported incidences at almost 25%. Common complications include loss of function, lack of blood return, poor quality waveforms and dislodgement, posing potential patient risks, and sudden loss of intra-arterial monitoring frequently requires prompt replacement. Contemporary research and technological improvements have highlighted several concepts to enhance the approach of RAC insertion and management while reducing immediate and late complications. The authors have prioritized the following 10 "best practice" aspects that may improve overall device function and reliability.

Preventing radial arterial catheter failure in critical care - Factoring updated clinical strategies and techniques.

Radial artery catheterization is a frequently performed procedure for critically ill patients. The correct function of arterial catheters is essential to provide accurate and continuous hemodynamic monitoring, facilitating intermittent blood sampling and helping to optimize the workload for critical care nurses and physicians. However, they are not without their own problems. This narrative practice review discusses several clinical aspects that are not frequently considered but may contribute to enhanced catheter functionality, less device-related failure and more acceptable dwell times. Ultrasound has demonstrated unequivocal efficacies and safety with the procedure, improving first attempt success rates with children, the obese or patients with unstable clinical vital signs and shock. Moreover, anatomic variations of the radial artery are not rare, and ultrasound-guided catheterization reduces the incidence of insertion-related complications such as hematoma, posterior wall puncture, intimal dissection, and radial nerve injury. Ultrasound guidance offers several immediate benefits by enhancing the most appropriate insertion techniques, allows for the correct catheter to vessel ratio measurements to be performed and reduces the angle of insertion, which may affect catheter failure due to inappropriate catheter length. A deeper and more proximal cannulation site at least 4 cm from wrist joint, avoiding the area of wrist flexion, reduces mechanical complications related to patient movements and may improve catheter functionality and dwell along with a better area for stabilization and securement.

Logistic Red Flags in Mass-Casualty Incidents and Disasters: A Problem-Based Approach.

BACKGROUND: Mass-casualty incidents (MCIs) and disasters are characterized by a high heterogeneity of effects and may pose important logistic challenges that could hamper the emergency rescue operations.The main objective of this study was to establish the most frequent logistic challenges (red flags) observed in a series of Italian disasters with a problem-based approach and to verify if the 80-20 rule of the Pareto principle is respected. METHODS: A series of 138 major events from 1944 through 2020 with a Disaster Severity Score (DSS) ≥ four and five or more victims were analyzed for the presence of twelve pre-determined red flags.A Pareto graph was built considering the most frequently observed red flags, and eventual correlations between the number of red flags and the components of the DSS were investigated. RESULTS: Eight out of twelve red flags covered 80% of the events, therefore not respecting the 80-20 rule; the number of red flags showed a low positive correlation with most of the components of the DSS score. The Pareto analysis showed that potential hazards, casualty nest area > 2.5km2, number of victims over 50, evacuation noria over 20km, number of nests > five, need for extrication, complex access to victims, and complex nest development were the most frequently observed red flags. CONCLUSIONS: Logistic problems observed in MCIs and disaster scenarios do not follow the 80-20 Pareto rule; this demands for careful and early evaluation of different logistic red flags to appropriately tailor the rescue response.

Mass Gathering Emergency Medicine Organization for the Union of European Football Associations' Under-21 Championship 2019 in Bologna, Italy.

Football events represent a type of Mass Gathering Events (MGE) where crowd behavior, temperature and Heat Index, absence of free water, and alcohol consumption can lead to an increased need for medical assistance in participants. This report describes the environmental issues, organization, and healthcare assistance provided during the four matches of the Union of European Football Associations' (UEFA) Under-21 tournament held in Bologna in June, 2019. The four matches had a total of 72655 spectators; 31 patients required medical assistance with a mean Patient Presentation Rate (PPR) of 0.41; Mean Transport To Hospital Rate (TTHR) of 0.04; with PPR and TTHR comparable with literature findings. Majority of patients suffered from minor injuries and illnesses, and were treated directly in stadium medical sites. Medical assistance involved volunteer rescuers, emergency nurses, and physicians; resources were efficiently allocated and provided effective care to every patient.Climate factors, heat and humidity, the absence of free water, and increased alcohol consumption appear to be associated with increased requests for medical assistance. The retrospective analysis of a wider range of environmental factors, and the historical experience developed during similar MGEs suggest the need for a more comprehensive, improved approach for adequately assessing risk and planning the necessary healthcare resources.

In-Situ Simulation for Intensive Care Nurses During the COVID-19 Pandemic in Italy: Advantages and Challenges.

The COVID-19 pandemic required a global increase in intensive care unit (ICU) resources and the recruitment of a great number of nurses without any tprior critical care experience. The opportunities for traditional education and supervised clinical training were limited to prevent infections. The massive increase of nursing staff resources required a rethinking of the usual educational strategies for newly acquired nurses. This short communication describes our experience of an "in-situ" simulation training course in an Italian tertiary level hospital. A series of two-part classes were structured with short lectures on fundamental principles of intensive care nursing and brief hands-on sessions, and a set of simulated scenarios, based upon the most common situations to be faced in the ICU. In-situ simulation offers greater realism and transferability and represents a cost-effective strategy, avoiding the costs and the maintenance of a dedicated simulation center. The simulated multidisciplinary teamwork in the real ICU setting contributes to an effective experiential learning, improving staff familiarity with devices, equipment, and environment, and allows trainees to improve both technical and nontechnical skills.
