Prehospital Emergency Care最新文献

This prologue to the NAEMSP Prehospital Trauma Compendium describes the rationale for and the process used in developing the compendium manuscripts. It also provides a summary of other contemporary works discussing additional elements of prehospital trauma care including hemorrhage control, airway and ventilation management, pain management, care for traumatic brain injury, and trauma triage.

Objectives: The epidemic of opioid use disorder (OUD) remains pervasive in the United States. In an effort to increase the availability and timeliness of medications for opioid use disorder (MOUD), several agencies in the United States (US) offer buprenorphine by prehospital providers to selected patients, though published data remains limited. We describe the preliminary safety and feasibility of training all paramedics within a single agency to administer buprenorphine in the field without online medical control to simultaneously treat opioid withdrawal and initiate MOUD.

Methods: Using data from an ongoing quality assurance (QA) database, cases were retrospectively reviewed. Inclusion criteria included administration of buprenorphine by paramedics; cases were excluded if administered prior to EMS arrival on scene (i.e., the patient was given buprenorphine by a bystander or took their own). Data were entered into a REDCap database as part of the ongoing QA process. The primary reported outcome was administration of buprenorphine without complications. Complications were defined as any adverse effects from the administration of medication, including but not limited to new or worsening opioid withdrawal symptoms.

Results: In total, 121 patients met inclusion criteria, 82 were treated for naloxone-induced withdrawal and 39 for withdrawal due to opioid cessation. There were no cases of precipitated withdrawal or worsening of patient condition observed. Adverse effects were limited to three cases of nausea and vomiting post-administration, all of which were present prior to buprenorphine administration. No patients met the primary outcome of adverse effects from medication administration.

Conclusions: In a single prehospital system, the use of buprenorphine appears to be a feasible and safe strategy for treating patients experiencing acute opioid withdrawal.

Objectives: The combination of broad conditional applicability and ease of data collection make some general risk scores an attractive tool for clinical decision making under acute care conditions. To date, general risk scores have demonstrated moderate levels of accuracy for key outcomes, but there are no definitive general scores integrated universally into prehospital care. The objective of our study was to demonstrate a relationship between the Revised Trauma Score (RTS) and prehospital lifesaving interventions (LSI) and downstream hospital mortality among a large, diverse, multi-year cohort of critical care transport patients. We hypothesized that the RTS is associated with mortality and prehospital LSI generally across all conditions, including non-trauma.

Methods: We conducted a retrospective observational study using a pre-established cohort of sequentially enrolled patients from a regional air medical service between the years 2012 and 2021. Pediatric patients, non-transports, and those transported to hospitals outside the regional health system were excluded from the study. Both trauma and non-trauma patients were included in this study. We performed logistic regressions to evaluate the association between RTS and the outcomes of LSI and hospital mortality, while controlling for age, sex, and medical category. Graphs were constructed to plot RTS against prehospital LSI and survival percentage.

Results: Our final patient cohort was 62,424 patients. 58.4% of all patients required a prehospital LSI. Non-trauma cases made up 69.7% of the patient population. The Revised Trauma Score was inversely proportional with both prehospital LSI and mortality. The logistic regression model yielded an odds ratio (OR) of 0.55 (95% CI 0.54 - 0.56) for the association between RTS and death. Additionally, when the components of RTS were associated with mortality, they each showed a statistically significant OR. The Revised Trauma Score was also associated with prehospital LSI (OR 0.10; 95% CI 0.03 - 0.33).

Conclusions: In a large helicopter EMS cohort of both trauma and non-trauma patients, the RTS was inversely associated with prehospital LSI and hospital mortality. The generalized utility of RTS demonstrated in our study warrants further investigation of this measure as a broader triage tool.

Most patients with serious illness prefer to die at home; however, for those requiring ongoing ventilatory support, this preference is often not honored due to the difficulties of arranging a palliative extubation at home. Here we present two cases of successful home palliative extubations, coordinated by a multidisciplinary team including critical care, palliative care, care management, hospice, and emergency medical services (EMS) clinicians. By exploring the operational and regulatory challenges accompanying these cases, we provide a road map for offering mechanically ventilated patients the choice of a death at home and provide truly holistic and patient-centered care.

Objectives: Early initiation of targeted temperature management (TTM) is crucial for post-resuscitation care. Although TTM is initiated prior to transport and continued during interhospital transport (IHT), its feasibility and safety during IHT for cardiac arrest patients have not been thoroughly assessed. This study aims to evaluate the feasibility and safety of interhospital TTM for post-resuscitation patients.

Methods: A retrospective analysis of post-cardiac arrest patients transported by a dedicated critical care transport team between January 2016 and April 2023 was conducted. Adult patients resuscitated from cardiac arrest without mental recovery were enrolled. The study population was divided into those who received TTM during IHT (IHT-TTM group) and those who did not (non-IHT-TTM group). The primary outcome was body temperature drop during transport, with hypotension, or desaturation during transport considered as secondary outcomes. Multivariable conditional logistic regression analysis was performed after frequency matching.

Results: Among 593 post-cardiac arrest patients, 332 were included in the analysis after exclusions. Of these, 44 (13.3%) received TTM during IHT. Conditional logistic regression analysis showed significantly higher likelihood for a drop in body temperature during IHT for the IHT-TTM group, with an odds ratio (OR) of 12.91 (95%CI: 5.28-31.53). No significant association was found for hypotension (OR (95%CI): 0.72 (0.13-3.97)), or desaturation during IHT (0.65 (0.15-2.82)).

Conclusions: Administration of TTM during IHT for post-cardiac arrest patients appears to be feasible and safe. These findings support the implementation of dedicated critical care transport systems capable of providing TTM during IHT for post-cardiac arrest patients.

Objectives: The quality of prehospital resuscitation provided by emergency medical technicians (EMTs) is essential to ensure better outcomes following out-of-hospital cardiac arrests (OHCA). We assessed the quality of prehospital resuscitation by recording time to key prehospital interventions using EMT-worn video devices and investigated its association with outcomes of patients with OHCA.

Methods: This retrospective, cross-sectional study included cases of non-traumatic OHCA in adults treated by emergency medical services (EMS) in Hsinchu City, Taiwan, during 2022 and 2023. We used data from high-resolution, chest-mounted wearable cameras to define and measure six quality indices (QIs) for prehospital resuscitation interventions (i.e., time spent recognizing OHCA). To evaluate the association between QI performance and sustained return of spontaneous circulation (ROSC), we used multivariable logistic regression.

Results: Of 745 patients eligible for this study, 187 (25.1%) achieved sustained ROSC. Six core QIs were analyzed: recognition of OHCA (median time: 9.0 s), time from recognizing OHCA to initiating cardiopulmonary resuscitation (cardiopulmonary resuscitation [CPR]; 9.0 s), automated external defibrillator setup (34.0 s), time from recognizing OHCA to beginning ventilation (160.0 s), advanced airway management (300 s), and deploying a mechanical CPR device (50 s). The performance of the six QIs were not associated with sustained ROSC (Adjusted odds ratio [95% confidence interval]: 1.00 [0.99-1.00], 0.99 [0.98-1.00], 1.00 [1.00-1.01], 1.00 [1.00-1.00], 1.00 [1.00-1.00], and 0.99 [0.99-1.00], respectively).

Conclusions: This study describes the rate of sustained ROSC and time to key interventions captured by EMT-worn video devices in non-traumatic OHCA patients. Although we found no direct link between QI performance and improved OHCA outcomes, this study highlights the potential of video-assisted QIs to enhance the documentation and understanding of prehospital resuscitation processes. These findings suggest that further refinement and application of these QIs could support more effective resuscitation strategies and training programs.

Objectives: This study explores the relationship between socioeconomic factors and pediatric opioid-related emergencies requiring naloxone administration in the prehospital setting, an escalating public health concern.

Methods: A retrospective analysis of the National Emergency Medical Services Information System (NEMSIS) database was conducted, examining data from pediatric opioid-related EMS activations between January 2018 and December 2021. The Social Vulnerability Index (SVI) was used to gauge each incident's socioeconomic context and assess correlations between SVI scores and the likelihood of opioid-related activations and naloxone interventions.

Results: A total of 7,789 pediatric opiate-related EMS activations were identified. Lower socioeconomic status (SES) areas (higher SVI scores) exhibited a decreased rate of opioid-related activations compared to lower SVI-scored areas but an increased frequency of naloxone administration. The analysis demonstrated that as socioeconomic status (SES) improves, the likelihood of opioid-related activations increases significantly supported by a significant negative linear trend (Estimate = -0.2971, SE = 0.1172, z = -2.54, p = 0.0112. On the other hand, naloxone administration was more frequently required in lower SES areas, suggesting an increased emergency response in these (Estimate = 0.05806, SE = 0.2403, z = 0.24, p = 0.8091).

Conclusions: The analysis highlights a statistically significant correlation between the SES of an area and pediatric opioid-related EMS activations, yet an inverse correlation with the likelihood of naloxone administration. These findings demonstrate that in lower socioeconomic areas, the total number of opiate-related EMS activations is lower; however, naloxone was more likely to be deployed during those activations. This underscores the need for further research to understand the disparities in opioid crisis management across different socioeconomic landscapes.

Objectives: Evidence-based guidelines (EBGs) are widely recognized as valuable tools to aggregate and translate scientific knowledge into clinical care. High-quality EBGs can also serve as important components of dissemination and implementation efforts focused on educating emergency medical services (EMS) clinicians about current evidence-based prehospital clinical care practices and operations. We aimed to perform the third biennial systematic review of prehospital EBGs to identify and assess the quality of prehospital EBGs published since 2021.

Methods: We systematically searched Ovid Medline and EMBASE from January 1, 2021, to June 6, 2023, for publications relevant to prehospital care, based on an organized review of the literature, and focused on providing recommendations for clinical care or operations. Included guidelines were appraised using the National Academy of Medicine (NAM) criteria for high-quality guidelines and scored using the Appraisal of Guidelines for Research and Evaluation (AGREE) II Tool.

Results: We identified 33 new guidelines addressing clinical and operational topics of EMS medicine. The most addressed EMS core content areas were time-life critical conditions (n = 17, 51.5%), special clinical considerations (n = 15, 45%), and injury (n = 12, 36%). Seven (21%) guidelines included all elements of the National Academy of Medicine (NAM) criteria for high-quality guidelines, including the full reporting of a systematic review of the evidence. Guideline appraisals by the Appraisal of Guidelines for Research and Evaluation (AGREE) II tool demonstrated modest compliance to reporting recommendations and similar overall quality compared to previously identified guidelines (mean overall domain score 67%, SD 12%), with Domain 5 ("Applicability") scoring the lowest of the six AGREE II domains (mean score of 53%, SD 13%).

Conclusions: This updated systematic review identified and appraised recent guidelines addressing prehospital care and identifies important targets for education of EMS personnel. Continued opportunities exist for prehospital guideline developers to include comprehensive evidence-based reporting into guideline development to facilitate widespread implementation of high-quality EBGs in EMS systems and incorporate the best available scientific evidence into initial education and continued competency activities.

Medically complex children present a low frequency but often high acuity patient population for emergency medical services (EMS) personnel. We present a case of a 12-year-old male with Duchenne muscular dystrophy and adrenal agenesis found unresponsive. Detailed history-taking was crucial for diagnostic accuracy and this patient's favorable outcome. This case highlights the importance of recognizing adrenal insufficiency-induced hypoglycemia in patients presenting with altered mental status. EMS personnel should be trained to identify and manage adrenal insufficiency, using detailed histories and on-scene medical oversight to improve outcomes.

Transgender and gender diverse (TGD) people have long faced significant barriers to safely accessing medical care-especially gender-affirming care, which has been shown to strikingly improve health outcomes like suicidality and depression. In the prehospital setting, gender-affirming care amounts to showing respect for the TGD patient's identified gender and maintaining a safe environment that fosters a positive therapeutic relationship throughout the encounter. This represents a challenge for many Emergency Medical Services (EMS) systems due to the lack of TGD-specific training for EMS clinicians, a paucity of TGD-specific research to inform EMS education and clinical care, and in some cases the resistance of EMS clinicians to such training. Transgender and gender diverse people are facing a regression in legal access to essential medical care. With this position statement, NAEMSP joins other professional medical societies in providing recommendations to improve care for TGD patients, thereby affirming TGD individuals' right to exist as their authentic selves, as well as their entitlement to the same high-quality prehospital medical care as their cisgender peers.
