Peru’s health infrastructures, particularly hospitals, are exposed to disaster threats of different natures. Traditionally, earthquakes have been the main disaster in terms of physical and structural vulnerability, but the coronavirus disease 2019 (COVID-19) pandemic has also shown their functional vulnerability. Public hospitals in Lima are very different in terms of year constructed, type of construction, and number of floors, making them highly vulnerable to earthquakes. In addition, they are subject to a high demand for care daily. Therefore, if a major earthquake were to occur in Lima, the hospitals would not have the capacity to respond to the high demand.

The aim of this study was to analyze the Hospital Safety Index (HSI) in hospitals in Lima (Peru).

This was a cross-sectional observational study of 18 state-run hospitals that met the inclusion criteria; open access data were collected for the indicators proposed by the Pan American Health Organization (PAHO) Version 1. Associations between variables were calculated using the chi-square test, considering a confidence level of 95%. A P value less than .05 was considered to determine statistical significance.

The average bed occupancy rate was 90%, the average age was 70 years, on average had one bed per 25,126 inhabitants, and HSI average score was 0.36 with a vulnerability of 0.63. No association was found between HSI and hospital characteristics.

Most of the hospitals were considered Category C in earthquake and disaster safety, and only one hospital was Category A. The hospital situation needs to be clarified, and the specific deficiencies of each institution need to be identified and addressed according to their own characteristics and context.

Foreign body airway obstruction (FBAO) is a life-threatening emergency, and the prognosis of patients with FBAO is greatly affected by the prehospital process. There are only a few large-scale studies analyzing prehospital process databases of the fire department.

The aim of this study was to investigate whether characteristics of patients with FBAO were associated with prehospital factors and outcomes.

In this retrospective observational study, patients transferred to the hospital by the Tokyo, Japan Fire Department for FBAO from 2017 through 2019 were included. The association between neurologically favorable survival among the characteristics of patients with FBAO and prehospital factors affecting the outcomes was evaluated.

Of the 2,429,175 patients, 3,807 (0.2%) patients had FBAO. The highest number of FBAO cases was 99 (2.6%), which occurred on January 1 (New Year’s Day), followed by 40 cases (1.1%) on January 2, and 28 cases (0.7%) on January 3. The number of patients who experienced out-of-hospital cardiac arrest (OHCA) caused by FBAO was 1,644 (43.2%). Comparing the OHCA and non-OHCA groups, there were significant differences in age, sex, time spent at the site, and distance between the site and hospital. Cardiac arrest was significantly lower in infants after FBAO (P < .001). In total, 98.2% of patients who did not have return of spontaneous circulation (ROSC) before hospital arrival died within 30 days, a significantly higher mortality rate than that in patients who had ROSC (98.2% versus 65.8%; P < .001).

Among patients who did not have ROSC following FBAO upon arrival at the hospital, 98.2% died within 30 days. Thus, it is important to remove foreign bodies promptly and provide sufficient ventilation to the patient at the scene to increase the potential for ROSC. Further, more precautions should be exercised to prevent FBAO at the beginning of the year.

Tourniquets are the standard of care for civilian and military prehospital treatment of massive extremity hemorrhages. Over the past 17 years, multiple military studies have demonstrated rare complications related to tourniquet usage. These studies may not translate well to civilian populations due to differences in baseline health. Experimental studies have demonstrated increased rates of post-traumatic acute kidney injuries (AKIs) in rats with obesity and increased oxidative stress, suggesting that comorbidities may affect AKI incidence with tourniquet usage. Two recently published retrospective studies, focused on the safety of tourniquets deployed within civilian sectors, documented increased incidence of AKI in patients with a prehospital tourniquet as compared to previously published military results. This study aimed to provide descriptive data concerning the association between the use of prehospital tourniquets and AKIs amongst civilian patient populations as AKIs increase mortality in hospitalized patients.

This was a single-center, observational, cross-sectional, pilot study involving chart review of participants presenting to a tertiary Level 1 trauma center. Patient data were extracted from prehospital and hospital electronic medical records. For this study, AKI was defined using the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines.

A total of 255 participants were included. Participants with a history of diabetes mellitus had a significantly higher incidence of AKI as compared to those without. Analysis revealed an increased odds of AKI with diabetes in association to the use of a prehospital tourniquet. Participants with diabetes had an increased relative risk of AKI in association to the use of a prehospital tourniquet. The incidence of AKI was statistically higher than what was previous reported in the military population in association with the use of a prehospital tourniquet.

The incidence of AKIs was higher than previously reported. Patients with diabetes had an associated higher risk and incidence of sustaining an AKI after the use of a prehospital tourniquet in association with the use of a prehospital tourniquet. This may be due to the known deleterious effects of diabetes mellitus on renal function. This study provides clinically relevant data that warrant further multi-site investigations to further investigate this study’s associated findings and potential causation. It also stresses the need to assess whether renally-impacting environmental and nutritional stressors affect AKI rates amongst military personnel and others in which prehospital tourniquets are used.

A 2018 poll by the American College of Emergency Physicians shows 93% of surveyed doctors believe their emergency department is not fully prepared for patient surge capacity in the event of a natural or man-made disaster. While an emergency disaster plan is activated during any incident where resources are overwhelmed, many US emergency physicians today think of a mass casualty incident (MCI) as the inciting event. To better prepare our communities, an MCI simulation took place in Chicago 2018 with participation from local and federal representatives. Included were Chicago fire, police, and emergency medical services agencies, emergency medicine physicians, resident participants, and medical student volunteer victims.

The study’s aim was to determine whether resource intensive moulage was an expected component or a beneficial adjunct, if moulage-based training would improve physician preparedness, and if such a training would increase the likelihood of future involvement in local disaster preparations. Analysis was performed on pre- and post-training surveys completed by participants. By reviewing the benefits versus cost, future MCI simulation planners can efficiently use their funds to achieve training goals.

Thirty-two emergency medicine physicians were surveyed before and after a five-hour training session on October 20, 2018, which included 89 moulage victims. Twenty-four after-event surveys were completed. All completed surveys were utilized in data analysis.

Of polled participants, a 68% improvement in general preparedness was achieved. While only 19% of participants cited current involvement in their facility’s disaster planning in pre-event survey, the likelihood of involvement after training was 8.2/10. Overall, the importance of moulage an essential component to such trainings remained constant.

Moulage is an expected and crucial element to MCI training and should be incorporated as extensively as resources allow. MCI trainings improve physician preparedness and potentially increase physician involvement in disaster planning at home institutions.

The Project for Strengthening the ASEAN Regional Capacity on Disaster Health Management (ARCH Project) developed Regional Collaboration Drills (RCDs) and is proposing an ASEAN Academic Network to strengthen capacity in disaster health management (DHM) in ASEAN Member States (AMS), as well as developing a standard training curriculum in DHM. This study aims to clarify the impacts and sustainability of the ARCH Project.

The four previous RCDs and the enhancement of academic activities were reviewed.

The ARCH Project developed the RCDs with simulation exercises based on possible disaster scenarios in each host country to test and validate the capacity of AMS International Emergency Medical Teams (I-EMTs), the Standard Operating Procedure (SOP) for I-EMT coordination, and regional tools, as well as the relevant domestic SOPs of the host countries for receiving international assistance. Following the RCD in Thailand, three AMS: Viet Nam, Philippines, and Indonesia, all of which are considered disaster-prone, successfully hosted RCDs with significant improvements. The project also established a sub-working group (SWG) to develop a standard curriculum in DHM. Two curricula developments, the Basic Course on DHM and In-Country Course for Coordination on EMTs, are on-going as part of the project activity. The establishment of the ASEAN Academic Network and the ASEAN Institute for DHM (AIDHM) are currently in the endorsement process of the ASEAN health sector.

The RCDs are very effective to test and to validate the SOP and regional tools developed, providing opportunities for AMS I-EMT to familiarize the tools, as well as for host countries to assess their coordination capacity for receiving international assistance and identifying the country’s specific challenges, and verifying ASEAN regional coordination mechanism. The development of the standard curriculum can enhance regional capacity both in supporting disaster-affected countries and in receiving international assistance. A sustainable capacity development mechanism in DHM is envisaged through the establishment of the ASEAN Academic Network and AIDHM toward the goal of One ASEAN One Response.

Weight estimation is required to enable dose calculations for weight-based drugs administered during emergency care. The accuracy of the estimation will determine the accuracy of the administered dose. This is an important matter of patient safety. The objective of this systematic review was to collect, review, evaluate, and create a synthesis of the current literature focusing on the accuracy of weight estimation in the prehospital environment.

This systematic review followed the PRISMA guidelines. Studies were identified and included if they were peer reviewed, full length, published in English, and contained original data. Studies utilizing any form of weight estimation methodology in the prehospital setting (in children or adults) were included. Data on the quality of the studies and accuracy of the weight estimation systems were extracted. Common themes were also identified.

Twenty-five studies met the inclusion criteria, with only nine studies (36.0%) containing useful weight estimation accuracy data. The overall quality of the studies was poor. The Broselow tape and paramedic estimates were the most studied methods of weight estimation, but there was insufficient evidence to support conclusions about accuracy. The major themes identified included the importance of accurate weight estimation and drug dosing as critical matters of patient safety, and the need for training to ensure these processes are performed accurately.

There were limited robust data identified on the accuracy of different weight estimation methods used in the prehospital setting. Future high-quality clinical research in this area is of critical importance to ensure patient safety in the prehospital environment.

Administration of epinephrine has been associated with worse neurological outcomes for survivors of out-of-hospital cardiac arrest. The publication of the 2018 PARAMEDIC-2 trial, a randomized and double-blind study of epinephrine in out-of-hospital cardiac arrest, provides the strongest evidence to date that epinephrine increases return of spontaneous circulation (ROSC) but not neurologically intact survival. This study aims to determine if Emergency Medical Services (EMS) cardiac arrest protocols have changed since the publication of PARAMEDIC-2.

States in the US utilizing mandatory or model state-wide EMS protocols, including Washington DC, were included in this study. The nontraumatic cardiac arrest protocol as of January 1, 2018 was compared to the protocol in effect on January 1, 2021 to determine if there was a change in the administration of epinephrine. Protocols were downloaded from the relevant state EMS website. If a protocol could not be obtained, the state medical director was contacted.

A 2021 state-wide protocol was found for 32/51 (62.7%) states. Data from 2018 were available for 21/51 (41.2%) states. Of the 11 states without data from 2018, all follow Advanced Cardiac Life Support (ACLS) guidelines in the 2021 protocol. Five (15.6%) of the states with a state-wide protocol made a change in the cardiac arrest protocols. Maximum cumulative epinephrine dose was limited to 4mg in Maryland and 3mg in Vermont. Rhode Island changed epinephrine in shockable rhythms to be administered after three cycles of cardiopulmonary resuscitation (CPR) and an anti-arrhythmic. Rhode Island also added an epinephrine infusion as an option. No states removed epinephrine administration from their cardiac arrest protocol. Simple statistical analysis was performed with Microsoft Excel.

Several states have adjusted cardiac arrest protocols since 2018. The most frequent change was limiting the maximum cumulative dosage of epinephrine. One state changed timing of epinephrine dosing depending on the rhythm and also provided an option of an epinephrine infusion in place of bolus dosing. While the sample size is small, these changes may reflect the future direction of prehospital cardiac arrest protocols. Significant limitations apply, including the exclusion of local and regional protocols which are more capable of quickly adjusting to new research. Additionally, this study is only focused on EMS in the United States.

Hemodynamic collapse in multi-trauma patients with severe traumatic brain injury (TBI) poses both a diagnostic and therapeutic challenge for prehospital clinicians. Brain injury associated shock (BIAS), likely resulting from catecholamine storm, can cause both ventricular dysfunction and vasoplegia but may present clinically in a manner similar to hemorrhagic shock. Despite different treatment strategies, few studies exist describing this phenomenon in the early post-injury phase. This retrospective observational study aimed to describe the frequency of shock in isolated TBI in prehospital trauma patients and to compare their clinical characteristics to those patients with hemorrhagic shock and TBI without shock.

All prehospital trauma patients intubated by prehospital medical teams from New South Wales Ambulance Aeromedical Operations (NSWA-AO) with an initial Glasgow Coma Scale (GCS) of 12 or less were investigated. Shock was defined as a pre-intubation systolic blood pressure under 90mmHg and the administration of blood products or vasopressors. Injuries were classified from in-hospital computed tomography (CT) reports. From this, three study groups were derived: BIAS, hemorrhagic shock, and isolated TBI without shock. Descriptive statistics were then produced for clinical and treatment variables.

Of 1,292 intubated patients, 423 had an initial GCS of 12 or less, 24 patients (5.7% of the original cohort) had shock with an isolated TBI, and 39 patients had hemorrhagic shock. The hemodynamic parameters were similar amongst these groups, including values of tachycardia, hypotension, and elevated shock index. Prehospital clinical interventions including blood transfusion and total fluids administered were also similar, suggesting they were indistinguishable to prehospital clinicians.

Hemodynamic compromise in the setting of isolated severe TBI is a rare clinical entity. Current prehospital physiological data available to clinicians do not allow for easy delineation between these patients from those with hemorrhagic shock.

During disasters and mass-casualty incidents (MCIs), there may be insufficient numbers of advanced life support (ALS) providers to provide intravenous (IV) access to all patients requiring parenteral fluids and/or medications. Enzyme-assisted subcutaneous infusion (EASI) access, in which human recombinant hyaluronidase (HRH) augments subcutaneous fluid dispersion and absorption, may be useful when ALS resources are insufficient to meet intravascular access needs. The utility of the use of the EASI lies, in part, in its ease of placement by ALS personnel.

The objectives of this study were to document the feasibility, comfort, and speed/degree of infused-glucose uptake through EASI lines placed by basic-level emergency medical technicians (EMT-Bs).

Eighteen EMT-Bs instituted EASI access on each other. A total of 150 units (1 mL) of HRH were administered through the EASI line, followed by the administration of 250 mL of tracer-labeled D5W. Timed phlebotomy enabled gas chromatography/mass spectrometry characterization of glucose uptake. Enzyme-assisted subcutaneous infusion placement and comfort ratings were tracked and analyzed using non-parametric statistics and Fisher's Exact Test.

In all 18 subjects, EASI access required only one attempt and was rated by the EMT-Bs as easy to accomplish. Glucose was absorbed quickly (within five minutes) in all subjects. The rate of infusion was rapid (median 393 mL/hour) and was comfortable for the recipients (median pain score 1/10).

The use of EASI may be viable as a fast, simple, and reliable method for the administration of fluid and glucose by EMT-Bs.
