Background The prehospital care of patients with sepsis are commonly performed by the emergency medical services. These patients may be critically ill and have high in-hospital mortality rates. Unfortunately, few patients with sepsis are identified by the emergency medical services, which can lead to delayed treatment and a worse prognosis. Therefore, early identification of patients with sepsis is important, and more information about the prehospital characteristics that can be used to identify these patients is needed. Based on this lack of information, the objectives of this study were to investigate the prehospital characteristics that are identified while patients with sepsis are being transported to the hospital by the emergency medical services, and to compare these values to those of the patients with and without adverse outcomes during their hospital stays. Methods This was a retrospective observational study. The patients’ electronic health records were reviewed and selected consecutively based on the following: retrospectively diagnosed with sepsis and transported to an emergency department by the emergency medical services. Data were collected on demographics, prehospital characteristics and adverse outcomes, defined as the in-hospital mortality or treatment in the intensive care unit, and analysed by independent sample t-test and chi-square. Sensitivity, specificity and likelihood ratio, of prehospital characteristics for predicting or development of adverse outcome were analysed. Results In total, 327 patients were included. Of these, 50 patients had adverse outcomes. When comparing patients with or without an adverse outcome, decreased oxygen saturation and body temperature, increased serum glucose level and altered mental status during prehospital care were found to be associated with an adverse outcome. Conclusions The findings suggests that patients having a decreased oxygen saturation and body temperature, increased serum glucose level and altered mental status during prehospital care are at risk of a poorer patient prognosis and adverse outcome. Recognizing these prehospital characteristics may help to identify patients with sepsis early and improve their long-term outcomes. However further research is required to predict limit values of saturation and serum glucose and to validate the use of prehospital characteristics for adverse outcome in patients with sepsis.

Introduction: 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. Study Objective: 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. Methods: 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. Results: 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. Conclusions: 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.

Aims and ObjectivesTo explore the onset of sepsis based on patients' and family members' experiences.BackgroundKnowledge about the onset of sepsis is limited among patients and their families, which makes early recognition of sepsis difficult. Previous studies argue that their stories are important to recognising sepsis and reduced suffering and mortality.DesignA descriptive design with a qualitative approach was used.MethodsIn total, 29 patients and family members participated in 24 interviews with open‐ended questions, including five dyadic and 19 individual interviews. The interviews were conducted during 2021, and participants were recruited from a sepsis group on social media. A thematic analysis based on descriptive phenomenology was performed. The study followed the COREQ checklist.FindingsTwo themes emerged from the experiences: (1) When health changes into something unknown, including the two subthemes; Bodily symptoms and signs being vague but still tangible and Feelings of uncertainty, and (2) Turning points when warnings signs are deemed as serious, including the two subthemes Passing borders when feeling out of control and Difficulties understanding the seriousness.ConclusionsPatients' and family members' stories of the onset of sepsis indicate that symptoms and signs appeared insidiously and then noticeably worsen. The symptoms and signs seemed not be attributed to sepsis; instead, there was uncertainty about what the symptoms and signs meant. It was mainly family members who possibly understood the seriousness of the disease.Implications for the profession and patient carePatients' experiences of their symptoms and signs and family members' unique knowledge of the patient, indicate that healthcare professionals should listen and try to understand what the patient and family members are telling and take their concerns seriously. How the condition appears, and family members' concerns are important pieces of the assessment to recognise patients with sepsis.Patient or public contributionPatients and family members contributed to the data collected.
