Request AccessThe Outcome of Walking Cold Patients with Potential Mild Hypothermia to Safety-A Mountain Rescue Case Series.
Wilderness and Environmental MedicineSome experts recommend that ambulant hypothermic patients should be rewarmed, fed, and not permitted to exercise for 30 min because of concerns that afterdrop can cause cardiac instability. We investigated the outcome of ambulant hypothermic patients in a case series from mountain rescue teams in Great Britain.
A questionnaire was used to collect information on a series of adult patients with a clinical diagnosis of mild hypothermia. All patients were alert on the AVPU scale and evacuated by walking from the mountain. The outcome measures were survival or a change in management because of medical deterioration during evacuation.
A series of 108 eligible cases were reported over a 5-year period. When rescuers arrived on the scene, 98 (91%) patients were stationary, and 10 (9%) were still mobile. Thirty-eight (39%) of the stationary cases were walked immediately off the mountain without any on-scene delay. In the remaining 60 (61%) stationary cases, the decision was taken to delay evacuation to provide food, drinks, and additional clothing. In 3 cases, the use of heat packs indicated an intention to actively rewarm. In cases where the on-scene time was reported, 27 (79%) were known to be mobile again within 20 min. All patients survived, and no adverse medical events occurred in all 108 cases.
In this study, no adverse events occurred because of immediate mobilization, suggesting that in these cases, there appears to be minimal risk of early activity.

Helping the Helpers: Mental Health Challenges of Psychosocial Support Workers During the Russian-Ukrainian War.
Disaster Prevention & ManagementThe ongoing Russian-Ukrainian war has been linked to mental health problems in the Ukrainian general population. To date, however, scarce research has examined the mental health of psychosocial support workers (PSWs) in Ukraine who have a burdensome workload in the context of ongoing conflict. This study aimed to examine the prevalence and correlates of burnout, posttraumatic stress disorder (PTSD), and suicidal ideation (SI) in PSWs in Ukraine during the Russian-Ukrainian war.
One hundred seventy-eight PSWs in Ukraine completed a survey assessing war exposure, mental health, and psychosocial characteristics.
A total 59.6% of PSWs screened positive for burnout, 38.2% for PTSD, and 10.7% for current SI. Lower optimism was associated with greater odds of burnout. Greater distress from witnessing war-related destruction, lower optimism, lower presence of meaning in life, and lower levels of close social relationships were associated with greater odds of burnout. Lower presence of meaning in life was associated with greater odds of SI.
Results of this study highlight the mental health challenges faced by PSWs in Ukraine during the ongoing Russian-Ukrainian war. They further suggest that interventions to foster meaning in life and promote social connectedness may "help the helpers" during this ongoing conflict.
Occupational and Personal Challenges During the Opioid Crisis: Understanding First Responders' Experiences and Viewpoints of Clients with Opioid Use Disorder.
Disaster Prevention & ManagementThis study provides preliminary findings on the experiences of first responders during the opioid crisis and their viewpoints regarding whether clients with opioid use disorder deserve medical rehabilitation. Understanding associations between first responder experiences and viewpoints of client deservedness can help reduce stigma, improve compassionate care, and identify training gaps.
Analyses were run with data from a nationwide survey of Emergency Medical Services-providers and law enforcement workers collected from August to November 2022 (N = 3836). The study used univariate statistics and ordered logistic regression to understand first responders' experiences and viewpoints on client deservedness, as well as the relationship between the two.
Results show a negative correlation between responding to overdose calls and perceiving clients with opioid use disorder as deserving of medical rehabilitation. Law enforcement, males, and conservatives also had negative viewpoints. Conversely, having a friend experience addiction and believing addiction has had a direct impact on respondents' lives predicted increases in client deservedness.
Policy should focus on creating spaces where first responders can have positive interactions with people who use drugs or are in recovery. Better training is needed to help first responders manage on-the-job stressors and understand the complexities of addiction.

Efficacy and Safety of High PEEP NIV in COVID-19 Patients.
Disaster Prevention & ManagementTo investigate the efficacy and safety of non-invasive ventilation (NIV) with high PEEP levels application in patients with COVID-19-related acute respiratory distress syndrome (ARDS).
This is a retrospective cohort study with data collected from 95 patients who were administered NIV as part of their treatment in the COVID-19 intensive care unit (ICU) at University Hospital Centre Zagreb between October 2021 and February 2022. The definite outcome was NIV failure.
High PEEP NIV was applied in all 95 patients; 54 (56.84%) patients could be kept solely on NIV, while 41 (43.16%) patients required intubation. ICU mortality of patients solely on NIV was 3.70%, while total ICU mortality was 35.79%. The most significant difference in the dynamic of respiratory parameters between 2 patient groups was visible on Day 3 of ICU stay: By that day, patients kept solely on NIV required significantly lower PEEP levels and had better improvement in PaO2, P/F ratio, and HACOR score.
High PEEP applied by NIV was a safe option for the initial respiratory treatment of all patients, despite the severity of ARDS. For some patients, it was also shown to be the only necessary form of oxygen supplementation.
Treatment Interruptions and Mortality among Puerto Rican Women with Gynecologic Cancers in Puerto Rico after Hurricanes Irma and María: A Retrospective Cohort Study.
Disaster Prevention & ManagementCancer patients are among the most vulnerable populations during and after a disaster. We evaluated the impact of treatment interruption on the survival of women with gynecologic cancer in Puerto Rico following hurricanes Irma and María.
Retrospective cohort study among a clinic-based sample of women diagnosed between January 2016-September 2017 (n=112). Women were followed up from their diagnosis until December 2019, to assess vital status. Kaplan-Meier survival curves and Cox proportional hazards models were performed.
Mean age was 56 (±12.3) years; corpus uteri (58.9%) was the most common gynecologic cancer. Predominant treatments were surgery (91.1%) and chemotherapy (44.6%). Overall, 75.9% were receiving treatment before the hurricanes, 16.1% experienced treatment interruptions and 8.9% died during the follow-up period. Factors associated with treatment interruption in bivariate analysis included younger age (≤55 years), having regional/distant disease, and receiving >1 cancer treatment (p<0.05). Crude analysis revealed an increased risk of death among women with treatment interruption (HR: 3.88, 95% CI=1.09-13.77), persisting after adjusting for age and cancer stage (HR: 2.49, 95% CI= 0.69-9.01).
Findings underscore the detrimental impact of treatment interruption on cancer survival in the aftermath of hurricanes, emphasizing the need for emergency response plans for this vulnerable population.
Applications and Performance of Machine Learning Algorithms in Emergency Medical Services: A Scoping Review.
Prehosp Disaster MedThe aim of this study was to summarize the literature on the applications of machine learning (ML) and their performance in Emergency Medical Services (EMS).
Four relevant electronic databases were searched (from inception through January 2024) for all original studies that employed EMS-guided ML algorithms to enhance the clinical and operational performance of EMS. Two reviewers screened the retrieved studies and extracted relevant data from the included studies. The characteristics of included studies, employed ML algorithms, and their performance were quantitively described across primary domains and subdomains.
This review included a total of 164 studies published from 2005 through 2024. Of those, 125 were clinical domain focused and 39 were operational. The characteristics of ML algorithms such as sample size, number and type of input features, and performance varied between and within domains and subdomains of applications. Clinical applications of ML algorithms involved triage or diagnosis classification (n = 62), treatment prediction (n = 12), or clinical outcome prediction (n = 50), mainly for out-of-hospital cardiac arrest/OHCA (n = 62), cardiovascular diseases/CVDs (n = 19), and trauma (n = 24). The performance of these ML algorithms varied, with a median area under the receiver operating characteristic curve (AUC) of 85.6%, accuracy of 88.1%, sensitivity of 86.05%, and specificity of 86.5%. Within the operational studies, the operational task of most ML algorithms was ambulance allocation (n = 21), followed by ambulance detection (n = 5), ambulance deployment (n = 5), route optimization (n = 5), and quality assurance (n = 3). The performance of all operational ML algorithms varied and had a median AUC of 96.1%, accuracy of 90.0%, sensitivity of 94.4%, and specificity of 87.7%. Generally, neural network and ensemble algorithms, to some degree, out-performed other ML algorithms.
Triaging and managing different prehospital medical conditions and augmenting ambulance performance can be improved by ML algorithms. Future reports should focus on a specific clinical condition or operational task to improve the precision of the performance metrics of ML models.

Rapid Ultrasonography for Shock and Hypotension Protocol Performed using Handheld Ultrasound Devices by Paramedics in a Moving Ambulance: Evaluation of Image Accuracy and Time in Motion.
Prehosp Disaster MedHandheld ultrasound (US) devices have become increasingly popular since the early 2000s due to their portability and affordability compared to conventional devices. The Rapid Ultrasonography for Shock and Hypotension (RUSH) protocol, introduced in 2009, has shown promising accuracy rates when performed with handheld devices. However, there are limited data on the accuracy of such examinations performed in a moving ambulance. This study aimed to assess the feasibility and accuracy of the RUSH protocol performed by paramedics using handheld US devices in a moving ambulance.
The study aimed to examine the performability of the RUSH protocol with handheld US devices in a moving ambulance and to evaluate the accuracy of diagnostic views obtained within an appropriate time frame.
A prospective study was conducted with paramedics who underwent theoretical and practical training in the RUSH protocol. The participants performed the protocol using a handheld US device in both stationary and moving ambulances. Various cardiac and abdominal views were obtained and evaluated for accuracy. The duration of the protocol performance was recorded for each participant.
Nine paramedics completed the study, with 18 performances each in both stationary and moving ambulance groups. The accuracy of diagnostic views obtained during the RUSH protocol did not significantly differ between the stationary and moving groups. However, the duration of protocol performance was significantly shorter in the moving group compared to the stationary group.
Paramedics demonstrated the ability to perform the RUSH protocol effectively using handheld US devices in both stationary and moving ambulances following standard theoretical and practical training. The findings suggest that ambulance movement does not significantly affect the accuracy of diagnostic views obtained during the protocol. Further studies with larger sample sizes are warranted to validate these findings and explore the potential benefits of prehospital US in dynamic environments.
Perceptions of Healthcare Workers on the Attributes of the Integrated Disease Surveillance and Response System in Zimbabwe.
Disaster Prevention & ManagementTo investigate healthcare workers' perceptions of the integrated disease surveillance and response (IDSR) strategy.
A cross-sectional survey of healthcare workers (HCWs) was conducted from December 2021 to June 2022 to assess their perceptions of the IDSR system attributes.
Of the 409 respondents, 12 (2.9%) reported no prior training on disease surveillance. The IDSR was deemed simple, acceptable, useful, and timely by most participants. There were sharp differences in perceptions of flexibility and simplicity between doctors and the other healthcare professionals. However, acceptability, timeliness, and usefulness were uniformly perceived. Healthcare workers with at least 11-years' experience perceived the usefulness of the IDSR system significantly higher than those with lesser years of experience. However, work experience did not have an impact on HCWs perceptions of the simplicity, timeliness, and flexibility of the IDSR system.
Most healthcare workers have positive perceptions of the IDSR approach. However, there are reservations about how well the system can adapt to changing conditions and demands (flexibility) and how well it simplifies the implementation processes. These findings demonstrate the necessity of adopting cutting-edge strategies for capacity building as well as ongoing professional development of healthcare professionals responsible for the implementation of the IDSR strategy.
