Associated Factors of Patients' Survival in Out of Hospital Cardiac Arrest; a Cross-sectional Study.

Introduction: Chinese populations have an increasingly high prevalence of cardiac arrest. This study aimed to investigate the prehospital associated factors of survival to hospital admission and discharge among out-of-hospital cardiac arrest (OHCA) adult cases in Macao Special Administrative Region (SAR), China. Methods: Baseline characteristics as well as prehospital factors of OHCA patients were collected from publicly accessible medical records and Macao Fire Services Bureau, China. Demographic and other prehospital OHCA characteristics of patients who survived to hospital admission and discharge were analyzed using multivariate logistic regression analysis. Results: A total of 904 cases with a mean age of 74.2±17.3 (range: 18-106) years were included (78%>65 years, 62% male). Initial shockable cardiac rhythm was the strongest predictor for survival to both hospital admission (OR=3.57, 95% CI: 2.26-5.63; p<0.001) and discharge (OR=12.40, 95% CI: 5.70-26.96; p<0.001). Being male (OR=1.63, 95% CI:1.08-2.46; p =0.021) and the lower emergency medical service (EMS) response time (OR=1.62, 95% CI: 1.12-2.34; p =0.010) were also associated with a 2-fold association with survival to hospital admission. In addition, access to prehospital defibrillation (OR=4.25, 95% CI: 1.78-10.12; p <0.001) had a 4-fold association with survival to hospital discharge. None of these associations substantively increased with age. Conclusion: The major OHCA predictors of survival were initial shockable cardiac rhythm, being male, lower EMS response time, and access to prehospital defibrillation. These findings indicate a need for increased public awareness and more education.

Effectiveness of the Abdominal Thrust Maneuver for Airway Obstruction Removal: Analysis of Data from the National Emergency Medical Services Information System.

BACKGROUND: Foreign body airway obstruction (FBAO) is a life-threatening emergency. Abdominal thrusts are recommended as first aid, but the success rate for this technique is unclear. Using information from a large database of emergency medical services (EMS) data in the United States, we evaluated the success rate of abdominal thrusts and identified patient characteristics that were associated with the success of the technique. METHODS: A retrospective observational study was conducted using data from the National Emergency Medical Services Information System (NEMSIS) to ascertain the success of abdominal thrusts in patients with FBAO from nearly 14,000 EMS agencies. Success was defined by positive evaluations on subjective and objective EMS criteria. RESULTS: Analysis of 1,947 cases yielded a 46.6% success rate for abdominal thrusts in removing obstructions. The age distribution was bimodal, with peaks during infancy and old age. June had the highest incidence of FBAO. Incidents were most frequent during lunch and dinner times, and most cases occurred in private residences. The first-time success rate was 41.5%, and a lower level of impaired consciousness was associated with lower success rates. A lower incidence of cardiac arrest was noted in successful cases. The success rate was high (60.2%) for children (age ≤15 years), with differences in demographic characteristics and a lower rate of impaired consciousness and cardiac arrests, as compared with unsuccessful interventions in the same age group. CONCLUSIONS: Our study showed a 46.6% success rate for abdominal thrusts in patients with FBAO. The success group had a lower proportion of impaired consciousness and cardiopulmonary arrest than the failure group. Future studies should attempt to identify the most effective maneuvers for clearing airway obstruction.

Successful prehospital ECMO in drowning resuscitation after prolonged submersion.

An 18-year-old drowning victim was successfully resuscitated using prehospital veno-arterial extracorporeal membrane oxygenation (VA-ECMO). Despite 24 min of submersion in water with a surface temperature of 15 °C, the patient was cannulated on-scene and transported to a trauma center. After ICU admission on VA-ECMO, he was decannulated and extubated by day 5. He was transferred to a peripheral hospital on day 6 and discharged home after 3.5 weeks with favorable neurological outcome of a Cerebral Performance Categories (CPC) score of 1 out of 5. This case underscores the potential of prehospital ECMO in drowning cases within a well-equipped emergency response system.

Analysis of barriers associated with emergency medical service activation in patients with acute stroke and acute myocardial infarction from Zhongjiang County of Sichuan Province in China.

OBJECTIVES: The purpose of this study was to investigate the preferred modes of transportation to the hospital among patients with acute stroke and acute myocardial infarction (AMI), as well as to identify the factors that influence the utilization of ambulances. METHODS: We conducted a cross-sectional study, including patients who were diagnosed with acute stroke and AMI, at the people's hospital of Zhongjiang, from September 30th, 2022 to August 30th, 2023. All patients were divided into emergency medical service (EMS)-activation group and self-transportation group. Chi-square and t-tests were utilized to discern differences between groups at baseline. To screen relevant variables, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis using R package glmnet. Subsequently, we performed a logistic regression analysis to identify predictors of EMS activation according the results of LASSO regression. RESULTS: we collected 929 valid questionnaires. 26.16% of the patients required the services of EMS. 90.9% of individuals have not received any formal first aid education. 42.1% of them reported that they had no understanding of cardiovascular and cerebrovascular diseases. Diagnosed as AMI (OR 0.22, 95%CI 0.06 to 0.88) or acute cerebral infarction (OR 0.26, 0.10 to 0.68), the distance between the patient and the nearest 120 network hospital when the patient had these symptoms (OR 0.97, 0.94 to 0.99), the patient's son or daughter was there when the patient was symptomatic (OR 0.58, 0.37 to 0.94), the patient (OR 0.19, 0.05 to 0.72) and the patient's partner (wife or husband) (OR 0.36, 0.16 to 0.85) had decided that the patient needed further medical help, Among patients who did not seek immediate help after symptom onset, thinking that the symptoms will disappear spontaneously (OR 0.34, 0.13 to 0.92) or not wanting to disturb others (OR 0.06, 0.01 to 0.66) or believing that they are not important symptoms (OR 0.15, 0.05 to 0.42) were factors independently associated with less ambulance use. Age (OR 1.02, 1.00 to 1.04), Stroke patients have experienced symptoms of disturbance of consciousness or convulsions (OR 2.99, 1.72 to 5.2) were independent factors associated with increased ambulance use. CONCLUSION: There is still ambulance underutilization among patients with acute stroke and AMI in county territory of China. Moreover, it is needed to raise the level of first aid education and awareness about EMS. Additionally, private clinic doctors and the public should gain adequate understanding of the severity of acute stroke and AMI, as well as their common symptoms, the crucial importance of prompt medical intervention. Finally, we propose that all township hospitals should be integrated into the 120 emergency networks and equipped with emergency first aid capabilities, pre-hospital care, and transportation abilities.

The Impact of COVID-19 on Suicidal Behavior in King Abdulaziz Medical City in Saudi Arabia.

INTRODUCTION:  During the COVID-19 pandemic, there has been a global increase in mental health issues, including suicidal behaviors. This study focuses on assessing the impact of the pandemic on the prevalence and characteristics of suicidal behavior at King Abdulaziz Medical City in Riyadh, Saudi Arabia. METHODS: A retrospective cohort study was conducted on 580 patients from January 2017 to December 2022, focusing on those aged 18 and above referred for suicide evaluation. Data were collected via chart reviews and analyzed using Statistical Product and Service Solutions (SPSS, version 25; IBM SPSS Statistics for Windows, Armonk, NY). RESULTS: Our study reviewed 580 patient charts, with 555 (95.7%) meeting the inclusion criteria. The majority of participants were in the 18-29 age group (66.7%). We observed an increase in the number of cases undergoing suicide attempt assessment post COVID-19, with 296 incidents (53.3%) from March 2020 to December 2022 (about a year and eight months), compared to 259 incidents (46.7%) from January 2017 to March 2020 (over three years). A significant post-pandemic increase was noted in individuals with secondary education or higher (p = 0.004). No significant changes were found in other demographic variables or in the profiles of individuals with an intention to end life before and after the pandemic. CONCLUSION: The study highlights the nuanced impact of the COVID-19 pandemic on suicidal behavior in Saudi Arabia, revealing an increased demand for suicide assessments, particularly among educated individuals. However, no corresponding increase was observed in the rate of high-intent suicidal cases or other significant variables. The findings underscore the complexity of factors influencing suicidal behavior during the pandemic and the need for targeted mental health interventions. Future research, ideally supported by a national database, is essential for a comprehensive understanding of suicidal behavior in Saudi Arabia.

Exploring stress management strategies among emergency medical service providers in Iran: a qualitative content analysis.

BACKGROUND: Emergency medical service providers are frequently exposed to a variety of stressors as a result of their work environment. These stressors can have detrimental effects on both the physical and mental well-being of individuals. This study was conducted with the aim of exploring stress management strategies in emergency medical service providers. METHODS: This study was conducted in 2023 using a qualitative approach and content analysis method. A purposive sampling method was used to include 16 emergency medical system providers from Hamadan city. Semi-structured interviews, with a duration of 45-60 min, were conducted for data collection. The Data were analyzed using Graneheim and Lundman's conventional content analysis approach. RESULTS: The analysis of the interview data revealed three themes: readiness for the worst conditions, assistance based on supportive partnerships, and striving for balance. The six categories within these three themes were mental preparation, risk management, collaborations in emergency response, supportive communication, adaptive behaviors, and maladaptive responses. CONCLUSIONS: The results of this study shed light on the various stress management strategies employed by emergency medical service providers. Understanding and implementing effective stress management strategies can not only enhance the well-being of emergency medical service providers but also improve the quality of patient care. Further research and action are essential to promote the resilience and mental health of these professionals, ensuring their overall well-being and job satisfaction.

Utilization of emergency medical service and its associated factors among patients visited public hospitals at Hawassa City, Sidama Region, Ethiopia, 2023.

Background: The burden of emergency medical conditions is borne mostly by poorer nations, with a 6 % increase in deaths of adults and children due to emergency conditions between 1990 and 2015. Emergency medical service is crucial to improve outcomes of those injuries and other time-sensitive illnesses. However, access to emergency medical services in Hawassa City is still limited and its' utilization is influenced by different factors. Methods: A facility-based cross-sectional study was conducted among 422 randomly selected clients who visited the emergency service in public hospitals of Hawassa City. A structured interviewer-administered questionnaire adapted by reviewing previous literature was used. The collected data by using the Kobo toolbox was exported into a statical package for social science software for analysis. Descriptive statistics such as frequency, percentage, mean, and standard deviation were used. A binary logistic regression model at a 95 % confidence interval was used to declare an association between dependent and independent variables using the odds ratio. Results: All 422 participants completed the interview with a response rate of 100 %. The mean age of the study participants was 33.73 years with a 14.67 standard deviation. One quarter (24.9 % (95 % CI: 21.1-29.4)) of the study participants have utilized emergency medical services. Urban residence (AOR = 3.48, 95 % CI: 1.69-7.16), ever utilized ambulance service (AOR = 2.37, 95%CI: 1.21-4.67), having Red Cross Association ambulance number (AOR = 2.64, 95%CI: 1.20-5.83) and awareness on presence of free government ambulance (AOR = 3.74, 95%CI: 1.46-9.59) were the predictors of the outcome variable. Conclusion: utilization of emergency medical services in the study area was relatively low when compared with other studies. urban residence, ever utilization of ambulance service, awareness of the presence of free government ambulances, and having a Red Cross Association ambulance number were predictors of utilization of emergency medical service.

A Case Study of Non-specialist Disease Management Using Teladoc Health Support: A Case Report.

In Japan, there is a shortage of emergency medicine specialists, often leading non-specialists (physicians who treat conditions outside their area of specialty) to handle cases outside their expertise, which can cause challenges and necessitate specialist support. Starting from December 2023, the St. Marianna University Hospital, which has emergency medicine specialists, began offering overnight emergency outpatient support to Kawasaki Municipal Tama Hospital using the Teladoc HEALTH Mini Cart telemedicine device (Teladoc Health, Inc., CA, USA). The case involved a 44-year-old male with a history of peritonsillar abscess and incisional drainage presented with pharyngeal pain. The treating physician at the Kawasaki Municipal Tama Hospital and a neurologist (the supported physician) examined the patient at 9 PM. An enlarged right tonsil was noted, and a peritonsillar abscess was suspected, prompting a contrast-enhanced CT scan. The results confirmed a 1 cm right peritonsillar abscess. Faced with the decision to transfer the patient to a higher medical facility, the supported physician consulted with the support physician through a Teladoc HEALTH Mini Cart. The St. Marianna University Hospital's emergency physician (supporting physician) used the Teladoc HEALTH Mini Cart to assess the patient's overall condition, blood tests, and CT images and advise on antibiotic treatment. A visit to the ear, nose, and throat expert (ENT) the following day was considered sufficient. The supported physician received feedback that the use of the Teladoc HEALTH Mini Cart reduced the burden of nighttime transfers for otolaryngological conditions, which can take several hours. This finding suggests that remote medical support can affect Japan's emergency medical system.

Prehospital neurologic assessment using mobile phones: Comparison between neurologists and emergency physicians.

BACKGROUND: Ambulance-based telestroke may be a promising solution to improving stroke care. We assessed the technical feasibility and reliability of prehospital evaluations using commercial mobile phones with fifth-generation wireless communication technology. METHODS: Six standardized patients portrayed scripted stroke scenarios during ambulance transport in an urban city and were remotely evaluated by independent raters using tablets (three neurologists and three emergency physicians) in a hospital, assisted by paramedics (trained in National Institute of Health Stroke Scale [NIHSS] assessment) in the ambulance; commercial cellular networks were utilized for videoconferencing transmission. The primary outcomes were mean difference (MD) and correlation of NIHSS scores between the face-to-face and remote assessments. We also examined the Bland-Altman plot for itemized NIHSS components, and Kaplan-Meier curves were used to compare the differences in the duration of the two evaluations between neurologists and emergency physicians. RESULTS: We conducted 32 ambulance runs and successfully completed all NIHSS examinations. No significant difference was found between the face-to-face and remote evaluations (MD, 0.782; 95% confidence interval [CI], -0.520-0.395). The correlation of NIHSS scores between the two methods was 0.994 (95% CI, 0.945-1.026), and three items exhibited the highest frequency of runs, with score differences between the two methods. There were no significant differences between neurologists and emergency physicians in the mean evaluation duration and NIHSS scores for the two methods. CONCLUSION: Prehospital evaluation using commercial mobile phones with fifth-generation wireless communication technology is feasible and reliable during ambulance transport in urban areas. Emergency physicians and neurologists performed similarly in stroke evaluations.

Nationwide status of aeromedical pre-hospital and retrieval medicine in Australia.

OBJECTIVE: To survey the current structure, capability and operational scope of pre-hospital and retrieval aeromedical teams across Australia. METHODS: The medical directors of all Australian civilian adult aeromedical retrieval organisations with pre-hospital teams and/or doctors for inter-hospital critical care patient transport were contacted in a survey to qualitatively assess capacity and team structure. RESULTS: All 17 organisations contacted completed the survey. While there is diversity in team structure with the pairing of doctors, paramedics and nurses, capacity for patient care is generally homogenous. A doctor/paramedic model is the more common team structure for rotary-wing missions, and doctor/nurse for fixed-wing. Differences are mostly due to state government controlled aspects of their health services. An advanced degree of intensive patient care occurs outside of the hospital. Land and sea rescue is an important aspect of Australian aeromedical work. CONCLUSION: Aeromedicine in Australia has many consistent elements, but variable contexts have resulted in a diversity of operational models.

Association of Advanced Airway Management in Preference to Intravenous Adrenaline on Neurological Outcomes Following Out-of-Hospital Cardiac Arrest.

AIM: To examine the preference for advanced airway management (AAM) or intravenous adrenaline administration (IVAd) provided by emergency medical services (EMS) for out-of-hospital cardiac arrest (OHCA) with shockable or nonshockable rhythms. METHODS: We conducted a retrospective analysis of a nationwide cohort of OHCA patients in Japan. Adult patients with witnessed collapse who were provided AAM and/or IVAd by EMS between June 2014 and December 2019 were divided into the AAM preferred group and IVAd preferred group, according to the initial advanced EMS intervention. The rates of favorable neurological outcomes (cerebral performance category 1 or 2 after 30 days) were compared between groups of patients with initial shockable or nonshockable rhythms. RESULTS: We analyzed 1365 and 9733 patients with initial shockable and nonshockable rhythms, respectively. Of these patients, 1033 (75.7%) with shockable and 7844 (80.6%) with nonshockable rhythms, respectively, were assigned to the AAM preferred group. Favorable neurological outcomes were significantly more frequent in the AAM preferred group than in the IVAd preferred group in patients with a shockable rhythm (13.6% vs 9.3%, respectively; P = 0.039), but not in those with a nonshockable rhythm (1.0% vs 0.8%, respectively; P = 0.509). Preferred AAM was independently associated with a higher probability of favorable neurological outcomes in patients with a shockable rhythm (adjusted odds ratio 1.66, 95% confidence interval 1.08-2.53, P = 0.020), but not in patients with a nonshockable rhythm. CONCLUSIONS: AAM provided by EMS in preference to IVAd was associated with the favorable neurological outcomes of OHCA patients with shockable rhythms.

Factors associated with difficulty in hospital acceptance during the COVID-19 pandemic period in Osaka Prefecture, Japan: a population-based study.

Background: In many countries, emergency medical systems were responsible for initial treatment of patients with COVID-19. Generally, acceptance by medical institutions may not be sufficient, and it may take much time to determine the medical institution to which to transport the patient. This problem is termed "difficulty in hospital acceptance (DIH)," and it is used as a key performance indicator in the assessment of the EMS in Japan. The purpose of this study was to reveal the factors associated with the DIH during the COVID-19 pandemic using dataset in the ORION (Osaka emergency information Research Intelligent Operation Network system). Methods: This was a retrospective descriptive study with a 3-year study period from January 1, 2019 to December 31, 2021. We included patients who were recorded in the ORION system during the study period. The primary endpoint was defined as DIH. Multivariable logistic regression model was used to assess factors associated with DIH during the COVID-19 pandemic and calculated their adjusted odds ratio (AOR) and associated 95% confidence interval (CI). Results: 1,078,850 patients included in this study. Of them, 41,140 patients (3.8%) experienced DIH and 1,037,710 patients (96.2%) did not experience DIH. The median age was 71 years (IQR: 45-82), and 543,760 patients (50.4%) were male. In this study, SpO2, body temperature, and epidemic period of COVID-19 were associated with difficulty in hospital acceptance. The highest AOR of SpO2 was 80% or less (AOR: 1.636, [95% CI: 1.532-1.748]), followed by 81-85% (AOR: 1.584, [95% CI: 1.459-1.721]). The highest AOR of body temperature was 38.0-38.9°C (AOR: 1.969 [95% CI: 1.897-2.043]), followed by 39°C or higher (AOR: 1.912 [95% CI: 1.829-1.998]). The highest AOR of epidemic period of COVID-19 was the 4th wave (AOR: 2.134, [95% CI: 2.065-2.205]), followed by the 3rd wave (AOR: 1.842, [95% CI: 1.785-1.901]). Conclusion: In this study, we revealed factors associated with the DIH during the COVID-19 pandemic. As various factors are involved in the spread of an unknown infectious disease, it is necessary not only to plan in advance but also to take appropriate measures according to the situation in order to smoothly accept emergency patients.

Resuscitation of out-of-hospital cardiac arrest victims in Austria's largest helicopter emergency medical service: A retrospective cohort study.

Background: Helicopter emergency medical services (HEMS) play a fundamental role in prehospital care. However, the impact of HEMS on survival of patients with out-of-hospital cardiac arrest (OHCA) is widely unknown. Therefore, the purpose of this study was to assess demographics, treatment, and outcome of patients with OHCA attended by physician-staffed helicopters. Methods: Retrospective cohort study enrolling OHCA patients treated by HEMS during a ten-year period (2010-2019) in Austria. Patients were identified using electronic mission records of 13 HEMS bases run by the Austrian Automobile, Motorcycle and Touring Club (OEAMTC), and subsequently matched with the national register of deaths to determine 30-day and one-year survival rates. Results are reported according to the 2015 Utstein Style. Multivariable logistic regression analysis was used to identify factors associated with patient outcome. Results: In total, 9344 presumed OHCA missions were identified. Cardiopulmonary resuscitation was attempted or continued by HEMS in 3889 cases. Approximately 32.2% of patients achieved return of spontaneous circulation (ROSC) and 22.5% sustained ROSC until arrival at the emergency department. Thirty-day and one-year survival rates were 14.0% and 12.4% respectively. HEMS response time, on-scene time, age, pathogenesis, arrest location, witness-status, first monitored rhythm, bystander automated external defibrillator (AED) use, airway type and administration of adrenaline were independent predictors of 30-day survival. Conclusions: This study provides an extensive insight into the management of OHCA in an almost nationwide HEMS sample. Thirty-day and one-year survival rates are high, indicating high-quality care and systematic selection of patients with favorable prognosis.

Tension Pneumoperitoneum: A Rare Complication of Cardiopulmonary Resuscitation (CPR).

Tension pneumoperitoneum is a surgical emergency. Although rare, failure to diagnose and treat the condition may be lethal. Hence, being aware of this phenomenon, particularly in scenarios involving cardiopulmonary resuscitation (CPR), is important. Existing literature emphasises immediate abdominal needle decompression as the initial management followed by close monitoring and keeping a low threshold for surgical intervention as a definitive measure. We decided to write up this case report to raise awareness that a tension pneumoperitoneum can result as a complication of CPR, a well-known and widely practiced algorithm.

Procedural sedation by advanced practice providers in the emergency medical service in the Netherlands: a retrospective study.

BACKGROUND: Procedural sedation and analgesia (PSA) is a technique of administering sedatives to induce a state that allows the patient to tolerate painful procedures while maintaining cardiorespiratory function, a condition that is frequently desired prehospital. Non-physician prehospital clinicians often have a limited scope of practice when it comes to providing analgesia and sedation; sometimes resulting in a crew request for back-up from physician-staffed prehospital services.". This is also the case if sedation is desirable. Advanced practice providers (APPs), who are legally authorized and trained to carry out this procedure, may be a solution when the physician-staffed service is not available or will not be available in time. METHODS: The aim of this study is to gain insight in the circumstances in which an APP, working at the Dutch ambulance service "RAV Brabant MWN" from January 2019 to December 2022, uses propofol for PSA or to provide sedation. With this a retrospective observational document study we describe the characteristics of patients and ambulance runs and evaluates the interventions in terms of safety. RESULTS: During the study period, the APPs administered propofol 157 times for 135 PSA and in 22 cases for providing sedation. The most common indication was musculoskeletal trauma such as fracture care or the reduction of joint dislocation. In 91% of the situations where propofol was used, the predetermined goal e.g. alignment of fractured extremity, repositioning of luxated joint or providing sedation the goal was achieved. There were 12 cases in which one or more adverse events were documented and all were successfully resolved by the APP. There were no cases of laryngospam, airway obstruction, nor anaphylaxis. None of the adverse events led to unexpected hospitalization or death. CONCLUSION: During the study period, the APPs performed 135 PSAs and provided 22 sedations. The success rate of predetermined goals was higher than that stated in the literature. Although there were a number of side effects, their incidences were lower than those reported in the literature, and these were resolved by the APP during the episode of care. Applying a PSA by an APP at the EMS "RAV Brabant MWN" appears to be safe with a high success rate.

Interstitial Lung Disease and Progressive Pulmonary Fibrosis: a World Trade Center Cohort 20-Year Longitudinal Study.

PURPOSE: World Trade Center (WTC) exposure is associated with obstructive airway diseases and sarcoidosis. There is limited research regarding the incidence and progression of non-sarcoidosis interstitial lung diseases (ILD) after WTC-exposure. ILD encompasses parenchymal diseases which may lead to progressive pulmonary fibrosis (PPF). We used the Fire Department of the City of New York's (FDNY's) WTC Health Program cohort to estimate ILD incidence and progression. METHODS: This longitudinal study included 14,525 responders without ILD prior to 9/11/2001. ILD incidence and prevalence were estimated and standardized to the US 2014 population. Poisson regression modeled risk factors, including WTC-exposure and forced vital capacity (FVC), associated with ILD. Follow-up time ended at the earliest of incident diagnosis, end of study period/case ascertainment, transplant or death. RESULTS: ILD developed in 80/14,525 FDNY WTC responders. Age, smoking, and gastroesophageal reflux disease (GERD) prior to diagnosis were associated with incident ILD, though FVC was not. PPF developed in 40/80 ILD cases. Among the 80 cases, the average follow-up time after ILD diagnosis was 8.5 years with the majority of deaths occurring among those with PPF (PPF: n = 13; ILD without PPF: n = 6). CONCLUSIONS: The prevalence of post-9/11 ILD was more than two-fold greater than the general population. An exposure-response gradient could not be demonstrated. Half the ILD cases developed PPF, higher than previously reported. Age, smoking, and GERD were risk factors for ILD and PPF, while lung function was not. This may indicate that lung function measured after respirable exposures would not identify those at risk for ILD or PPF.

Out-of-Hospital Cardiac Arrest in the Eye of the Beholder and Emergency Medical Service.

Purpose: Out-of-hospital cardiac arrest (OHCA) remains a global healthcare problem, with low survival and bystander cardiopulmonary resuscitation (CPR) rates. This study aimed to identify event-related factors in OHCA and their impact on return of spontaneous circulation (ROSC) achievement and maintenance until hospital admission. Patients and Methods: All data were collected from Utstein Resuscitation Registry Template for OHCA from The Institute of Emergency Medicine of Zagreb from January 2012 to August 2022. This cross-sectional research analyzed 2839 Utstein reports, including 2001 male, 836 female, and 8 subjects of unknown gender. The average age was 65.4 ± 16.2 years. Results: The most frequent place of collapse was private residence, and 27% of collapses were unwitnessed. Dispatcher-provided CPR instructions were provided in 39.7% of cases until the arrival of the emergency service team, which showed a very strong effect on bystander-provided CPR, and were followed in 68.4% of cases, while non-instructed bystander CPR was provided in only 7.9% of cases. Bystander CPR is more likely to be provided in public places than in private residences, often with both compression and ventilation. Bystander CPR was also more likely to be provided to men. Cases with bystander CPR, and compressions with ventilation compared to compression only CPR, showed a significantly greater success in maintaining ROSC later in CPR, both with moderate effects. Conclusion: Bystander CPR has been shown to have a significant role in achieving and maintaining ROSC until hospital admission. However, our results showed a location-dependent nature of bystanders' willingness to perform CPR as well as sex disparities in patients receiving CPR. With deficient education in basic life support in Croatia, dispatchers need to insist on and instruct bystander CPR performance.

The recovery processes among paramedics who encountered violence during work-a narrative interview study.

BACKGROUND: Almost all paramedics encounter workplace violence (WPV) during their careers. The most common form of WPV is verbal, and the perpetrator is usually the patient. It is known that paramedics suffer from post-traumatic stress disorder and other mental health problems, and WPV is one of the reasons behind that. Nevertheless, little is known about the recovery processes paramedics have had after encountering WPV. The research question was: What kind of recovery processes have paramedics had after encountering WPV? METHODS: A qualitative, narrative interview study was done. Data was collected in individual interviews with Finnish paramedics (n = 18). Paramedics were from different parts of Finland, and their ages varied from 24 to 49 years. They had been working in EMS for an average of 10.5 years (range 1.5 to 25 years). Interviews were conducted with a narrative approach, which enabled paramedics to narrate their experiences and speak on their own terms about the subject to the extent of their choosing. The data was analyzed using thematic analysis. RESULTS: Ten recovery process themes were identified: Strong psychological and physical reactions in a short time frame, Questioning one's profession and actions, Various support structures aided in recovery, Dysfunctional processes hindered recovery, Personal resources provided support, The support of the workcommunity as a lifeline, Left to cope alone, Permanent changes to work routines, Resulting in professional growth and Eternal crack in the shell. CONCLUSIONS: Many internal and external factors affect paramedics' recovery processes. While some receive adequate help, others struggle to get appropriate support, especially from their organization and supervisors. The findings of this study suggest that clear protocols should be established to help paramedics recover after encountering WPV and that an individual aspect should be kept in mind, as not everybody reacts in the same way.

Clinical Analysis of Postpartum Preeclampsia After an Uncomplicated Pregnancy.

Preeclampsia is a rare complication of pregnancy and can cause maternal death. This case report serves to increase awareness of the range and severity of symptoms in postpartum preeclampsia and highlights a stepwise approach to provide prompt management. The cause of preeclampsia is not fully understood but is correlated with many placental and maternal factors. Preeclampsia typically resolves with delivery, and it is uncommon to have symptoms in the postpartum period. Due to the rarity of the disease, it is not typically at the top of a differential list for postpartum women. A 35-year-old first-time mother presents with shortness of breath, tightness in her chest, and mild pulmonary edema. A series of chest X-rays, computed tomographic angiogram of the chest, and serial labs reveal she has postpartum preeclampsia. Many pre-eclamptic symptoms are common to a variety of conditions leading to an extensive list of differential diagnoses. Used in a stepwise fashion, clinical analysis allows physicians to accurately diagnose postpartum preeclampsia and provide lifesaving treatment for these mothers. This study highlights the need for vigilance in symptom analysis and diagnostic testing.
