The early recognition of patients with sepsis is difficult and the initial assessment outside of hospitals is challenging for ambulance clinicians (ACs). Indicators that ACs can use to recognize sepsis early are beneficial for patient outcomes. Research suggests that elevated point-of-care (POC) plasma glucose and serum lactate levels may help to predict sepsis in the ambulance service (AS) setting.

The aim of this study was to test the hypothesis that the elevation of POC plasma glucose and serum lactate levels may help to predict Sepsis-3 in the AS.

A prospective observational study was performed in the AS setting of Gothenburg in Sweden from the beginning of March 2018 through the end of September 2019. The criteria for sampling POC plasma glucose and serum lactate levels in the AS setting were high or intermediate risk according to the Rapid Emergency Triage and Treatment System (RETTS), as red, orange, yellow, and green if the respiratory rate was >22 breaths/minutes. Sepsis-3 were identified retrospectively. A primary and secondary analyses were carried out. The primary analysis included patients cared for in the AS and emergency department (ED) and were hospitalized. In the secondary analysis, patients who were only cared for in the AS and ED without being hospitalized were also included. To evaluate the predictive ability of these biomarkers, the area under the curve (AUC), sensitivity, specificity, and predictive values were used.

A total of 1,057 patients were included in the primary analysis and 1,841 patients were included in the secondary analysis. In total, 253 patients met the Sepsis-3 criteria (in both analyses). The AUC for POC plasma glucose and serum lactate levels showed low accuracy in predicting Sepsis-3 in both the primary and secondary analyses. Among all hospitalized patients, regardless of Sepsis-3, more than two-thirds had elevated plasma glucose and nearly one-half had elevated serum lactate when measured in the AS.

As individual biomarkers, an elevated POC plasma glucose and serum lactate were not associated with an increased likelihood of Sepsis-3 when measured in the AS in this study. However, the high rate of elevation of these biomarkers before arrival in hospital highlights that their role in clinical decision making at this early stage needs further evaluation, including other endpoints than Sepsis-3.

An Emergency Medical Service (EMS) is defined as a complete system that responds to public medical and surgical emergencies with prompt and adequate emergency care. Ambulance services are also classified as EMS in modern medical history. In the Nepalese context, prehospital care is very limited, and the EMS system is still a new concept in Nepal. In a study in the emergency room at Patan Hospital in Kathmandu, only 9.9% of patients came by ambulance, 53.6% by taxi, 11.4% by private car, 13.5% by bus, 5.4% by bicycle, and another 6.2% came with alternative routes.

This study aims to investigate the constraints, challenges, and achievements made by ambulances services during the coronavirus disease 2019 (COVID-19) pandemic.

The study design was phenomenological and the method was qualitative. In-depth interviews (IDIs) were conducted with six human resources working from the COVID-19 first wave pandemic in the ambulance service of Nepal Ambulance Service (NAS), Kathmandu.

Four themes were generated from IDIs: (1) challenges in service delivery; (2) constraints on service delivery; (3) working experiences; and (4) achievements of ambulatory service providers during the COVID-19 pandemic. Under these four themes, 12 sub-themes were constructed. The new nature of disease (COVID-19) in the first wave led to fear and anxiety, which also forced them to think about quitting the job; however, later on with proper training and safety measures, it led to working for COVID-19 patient transfers from home to hospital, as well as hospital to hospital, and proper prehospital care services were provided. The major challenges faced by ambulatory service providers were long working hours, wearing a single personal protective equipment (PPE) for long hours, confusing locations to pick up patients, and both stigma and discrimination.

From IDIs, it was concluded that although constraints and challenges arise during a pandemic, from proper guidance and support through NAS, they are able to provide proper prehospital care for the patient. Challenges like fear, heavy workload, PPE, and other material barriers do not hamper in service delivery.

Triage is the systematic prioritization of casualties when there is an imbalance between the needs of these casualties and resource availability. The triage sieve is a recognized process for prioritizing casualties for treatment during mass-casualty incidents (MCIs). While the application of a triage sieve generally is well-accepted, the measurement of its accuracy has been somewhat limited. Obtaining reliable measures for triage sieve accuracy rates is viewed as a necessity for future development in this area.

The goal of this study was to investigate how theoretical knowledge acquisition and the practical application of an aide-memoir impacted triage sieve accuracy rates.

Two hundred and ninety-two paramedics were allocated randomly to one of four separate sub-groups, a non-intervention control group, and three intervention groups, which involved them receiving either an educational review session and/or an aide-memoir. Participants were asked to triage sieve 20 casualties using a previously trialed questionnaire.

The study showed the non-intervention control group had a correct accuracy rate of 47%, a similar proportion of casualties found to be under-triaged (37%), but a significantly lower number of casualties were over-triaged (16%). The provision of either an educational review or aide-memoir significantly increased the correct triage sieve accuracy rate to 77% and 90%, respectively. Participants who received both the educational review and aide-memoir had an overall accuracy rate of 89%. Over-triaged rates were found not to differ significantly across any of the study groups.

This study supports the use of an aide-memoir for maximizing MCI triage accuracy rates. A “just-in-time” educational refresher provided comparable benefits, however its practical application to the MCI setting has significant operational limitations. In addition, this study provides some guidance on triage sieve accuracy rate measures that can be applied to define acceptable performance of a triage sieve during a MCI.

The aim of this study was to evaluate whether bystanders with no training in triage can correctly prioritize three injured patients by using a triage instrument.

An observational study was conducted. Participants performed a primary triage on three paper-based patient cases and answered 11 questions during a public event in the center of Stockholm, Sweden.

A total of 69 persons participated in the study. The success rate among all the participants for correct triage of the three patient cases was 52 percent. The female participants and younger participants (<55 years of age) performed correct triage to a greater extent. The over-triage was 12.5 percent and under-triage was 6.3 percent.

Participants with no prior knowledge of triage instruments may be capable of triaging injured patients with the help of an easy triage instrument. The over- and under-triage percentages were low, and this may indicate that the developed triage instrument is relatively easy to use. It may also indicate that bystanders can identify a severely injured patient.
