RESUMEN
BACKGROUND: Sepsis is a frequent cause of global deaths with time critical diagnosis and treatment impacting outcomes. Prehospital emergency nurses are pivotal in assessment that influences timely diagnosis. AIM: To gain a deep understanding of nurse's experiences when caring for those with suspected sepsis. DESIGN AND METHODS: A qualitative study using semi-structured interviews and inductive content analysis according to the Elo Kyngäs method. FINDINGS: Early identification of sepsis by prehospital emergency nurses (n = 13) was augmented through a combination of clinical experience and the implementation of practice guidelines. There were three key components to practice improvement a) clinical experience, b) continuous education and c) explicit guidelines. CONCLUSIONS: Identification of sepsis in the prehospital environment can shorten the time to treatment for patients with sepsis. Early identification can be achieved by continuous education in the Emergency Medical Service (EMS), ensuring experienced personnel and including the EMS in medical guidelines.
RESUMEN
BACKGROUND: Perioperative treatment of hypotension by intravenous administration of norepinephrine in a peripheral vein can lead to adverse events, for example, tissue necrosis. However, the incidence and severity of adverse events during perioperative administration are unknown. METHODS: This was a prospective observational study conducted at 3 Swedish hospitals from 2019 to 2022. A total of 1004 patients undergoing surgery, who met the criteria for perioperative peripheral norepinephrine administration, were included. The infusion site was inspected regularly. If swelling or paleness of skin was detected, the infusion site was changed to a different peripheral line. Systolic blood pressure and pulse frequency were monitored during the infusion time and defined as adverse events at >220 mm Hg and <40 beatsâ¢min -1 . In case of adverse events, patients were observed for up to 48 hours. The primary outcome was prevalence of extravasation, defined as swelling around the infusion site. Secondary outcomes were all types of adverse events and associations between predefined clinical variables and risk of adverse events. RESULTS: We observed 2.3% (95% confidence interval [CI], 1.4%-3.2%) extravasation of infusion and 0.9% (95% CI, 0.4%-1.7%) bradycardia. No cases of tissue necrosis or severe hypertension were detected. All adverse events had dissipated spontaneously within 48 hours. Proximal catheter placement was associated with more adverse events. CONCLUSIONS: Extravasation of peripherally administrated norepinephrine in the perioperative period occurred at similar rates as in previous studies in critically ill patients. In our setting, where we regularly inspected the infusion site and shifted site in case of swelling or paleness of skin, we observed no case of severe adverse events. Given that severe adverse events were absent, the potential benefit of this preventive approach requires confirmation in a larger population.

BACKGROUND: The benefits of helicopter emergency medical services (HEMS) transport of adults following major trauma have been examined with mixed results, with some studies reporting a survival benefit compared to regular emergency medical services (EMS). The benefit of HEMS in the context of the Swedish trauma system remains unclear. AIM: To investigate differences in survival and prehospital time intervals for trauma patients in Sweden transported by HEMS compared to road ambulance EMS. METHODS: A total of 74,032 trauma patients treated during 2012-2022 were identified through the Swedish Trauma Registry (SweTrau). The primary outcome was 30-day mortality and Glasgow Outcome Score at discharge from hospital (to home or rehab); secondary outcomes were the proportion of severely injured patients who triggered a trauma team activation (TTA) on arrival to hospital and the proportion of severely injured patients with GCS ≤ 8 who were subject to prehospital endotracheal intubation. RESULTS: 4529 out of 74,032 patients were transported by HEMS during the study period. HEMS patients had significantly lower mortality compared to patients transported by EMS at 1.9% vs 4.3% (ISS 9-15), 5.4% vs 9.4% (ISS 16-24) and 31% vs 42% (ISS ≥ 25) (p < 0.001). Transport by HEMS was also associated with worse neurological outcome at discharge from hospital, as well as a higher rate of in-hospital TTA for severely injured patients and higher rate of prehospital intubation for severely injured patients with GCS ≤ 8. Prehospital time intervals were significantly longer for HEMS patients compared to EMS across all injury severity groups. CONCLUSION: Trauma patients transported to hospital by HEMS had significantly lower mortality compared to those transported by EMS, despite longer prehospital time intervals and greater injury severity. However, this survival benefit may have been at the expense of a higher degree of adverse neurological outcome. Increasing the availability of HEMS to include all regions should be considered as it may be the preferrable option for transport of severely injured trauma patients in Sweden.

Head trauma is a common reason for emergency department visits, majority of these are mild traumatic brain injuries (mTBI). Only a small proportion of mTBI patients develop an intracranial hemorrhage and even fewer require neurosurgical intervention. To determine which patients require a brain computed tomography (CT) scan (without contrast), which patients can be discharged and which require hospitalization for observation, several steps are required. These include a thorough assessment of medical history and clinical examination. By utilizing established guidelines and analyzing the gathered information, it is possible to identify the appropriate course of action for each patient. Further management is based on findings on the brain CT scan.

Introduction: Fluid overload in patients in the intensive care unit (ICU) is associated with higher mortality. There are few randomized controlled trials to guide physicians in treating patients with fluid overload in the ICU, and no guidelines exist. We aimed to elucidate how ICU physicians from Nordic countries define, assess, and treat fluid overload in the ICU. Materials and methods: We developed an online questionnaire with 18 questions. The questions were pre-tested and revised by specialists in intensive care medicine. Through a network of national coordinators. The survey was distributed to a wide range of Nordic ICU physicians. The distribution started on January 5th, 2022 and ended on May 6th, 2022. Results: We received a total of 1,066 responses from Denmark, Norway, Finland, Sweden, and Iceland. When assessing fluid status, respondents applied clinical parameters such as clinical examination findings, cumulative fluid balance, body weight, and urine output more frequently than cardiac/lung ultrasound, radiological appearances, and cardiac output monitoring. A large proportion of the respondents agreed that a 5% increase or more in body weight from baseline supported the diagnosis of fluid overload. The preferred de-resuscitation strategy was diuretics (91%), followed by minimization of maintenance (76%) and resuscitation fluids (71%). The majority declared that despite mild hypotension, mild hypernatremia, and ongoing vasopressor, they would not withhold treatment of fluid overload and would continue diuretics. The respondents were divided when it came to treating fluid overload with loop diuretics in patients receiving noradrenaline. Around 1% would not administer noradrenaline and diuretics simultaneously and 35% did not have a fixed upper limit for the dosage. The remaining respondents 63% reported different upper limits of noradrenaline infusion (0.05-0.50 mcg/kg/min) when administering loop diuretics. Conclusion: Self-reported practices among Nordic ICU physicians when assessing, diagnosing, and treating fluid overload reveals variability in the practice. A 5% increase in body weight was considered a minimum to support the diagnosis of fluid overload. Clinical examination findings were preferred for assessing, diagnosing and treating fluid overload, and diuretics were the preferred treatment modality.
RESUMEN
INTRODUCTION: Mild traumatic brain injury (mTBI) is one of the most common reasons for emergency department (ED) visits. A portion of patients with mTBI will develop an intracranial lesion that might require medical or surgical intervention. In these patients, swift diagnosis and management is paramount. Several guidelines have been developed to help direct patients with mTBI for head CT scanning, but they lack specificity, do not consider the interactions between risk factors and do not provide an individualised estimate of intracranial lesion risk. The aim of this study is to create a model that estimates individualised intracranial lesion risks in patients with mTBI who present to the ED. METHODS AND ANALYSIS: This will be a retrospective cohort study conducted at ED hospitals in Stockholm, Sweden. Eligible patients are adults (≥15 years) with mTBI who presented to the ED within 24 hours of injury and performed a CT scan. The primary outcome will be a traumatic lesion on head CT. The secondary outcomes will be any clinically significant lesion, defined as an intracranial finding that led to neurosurgical intervention, hospital admission ≥48 hours due to TBI or death due to TBI. Machine-learning models will be applied to create scores predicting the primary and secondary outcomes. An estimated 20 000 patients will be included. ETHICS AND DISSEMINATION: The study has been approved by the Swedish Ethical Review Authority (Dnr: 2020-05728). The research findings will be disseminated through peer-reviewed scientific publications and presentations at international conferences. TRIAL REGISTRATION NUMBER: NCT04995068.

BACKGROUND: Critically ill COVID-19 patients have a high reported incidence of thromboembolic complications and the optimal dose of thromboprophylaxis is not yet determined. The aim of this study was to investigate if 90-day mortality differed between patients treated with intermediate- or high-dose thromboprophylaxis. METHOD: In this retrospective study, all critically ill COVID-19 patients admitted to intensive care from March 6th until July 15th, 2020, were eligible. Patients were categorized into groups according to daily dose of thromboprophylaxis. Dosing was based on local standardized recommendations, not on degree of critical illness or risk of thrombosis. Cox proportional hazards regression was used to estimate hazard ratios of death within 90 days from ICU admission. Multivariable models were adjusted for sex, age, body-mass index, Simplified Acute Physiology Score III, invasive respiratory support, glucocorticoids, and dosing strategy of thromboprophylaxis. RESULTS: A total of 165 patients were included; 92 intermediate- and 73 high-dose thromboprophylaxis. Baseline characteristics did not differ between groups. The 90-day mortality was 19.6% in patients with intermediate-dose and 19.2% in patients with high-dose thromboprophylaxis. Multivariable hazard ratio of death within 90 days was 0.74 (95% CI, 0.36-1.53) for the high-dose group compared to intermediate-dose group. Multivariable hazard ratio for thromboembolic events and bleedings within 28 days was 0.93 (95% CI 0.37-2.29) and 0.84 (95% CI 0.28-2.54) for high versus intermediate dose, respectively. CONCLUSIONS: A difference in 90-day mortality between intermediate- and high-dose thromboprophylaxis could neither be confirmed nor rejected due to a small sample size.

BACKGROUND: Prehospital care constitutes a work environment in which Prehospital Emergency Nurses (PENs) are exposed to traumatic situations that can lead to stress and increase their vulnerability to stress reactions. PENs' coping strategies after traumatic experiences have been little explored, which suggests that an investigation leading to a deeper understanding of their coping strategies is needed. AIM: To investigate and describe PENs' coping strategies after traumatic experiences. METHOD: A descriptive, inductive design with a qualitative research approach was used. Semi-structured interviews were analysed using Graneheim and Lundman's method of content analysis. Twelve PENs were interviewed. RESULTS: The main theme that emerged was: "a professional approach supports coping strategies for traumatic experiences". Being unprepared increases the feeling of vulnerability when facing a traumatic event, even though PENs acknowledge that traumatic events are unavoidable in their profession. Previous experiences and mental preparation help PENs to keep focused. To be able to act professionally, PENs distance themselves, thus acquiring a sense of control. Inter-professional teamwork can reduce the sense of aloneness. CONCLUSION: PENs' coping involves several strategies. Their own processing and understanding of an experience are crucial for the management of their own feelings, also affecting the care that PENs can offer the next patient. This study emphasises that a professional approach is the strongest coping strategy after traumatic events.

BACKGROUND: In the Swedish emergency medical services, single responder and assessment units have been implemented to meet the increasing need for ambulance assessment and care. AIM: To describe registered nurses experiences of care encounters as single responders in the emergency medical services. METHOD: The study design was descriptive with a qualitative approach. Semi-structured interviews with eight single responders were used together with inductive content analysis. RESULTS: From the theme which showed the experiences of being a single responder in the caring encounter in the ambulance care "meeting unique human care needs with conscious caution", three categories emerged: Increased risk-awareness, Lack of resource support creates vulnerability and Professional experiences and personal qualities contribute to patient safety. CONCLUSION: The single responders was aware of their vulnerability and a consistent theme was "caution". Risk assessments had evolved and were constantly present to maintain their own and the patient's safety. In critical patients, the experience of frustration and insufficiency dominated but at the same time there was a sense of meaningfulness. The main experience among all single responders was the feeling of getting close to the patient and responding to them in their own way.

Background: Secondary transports of patients suffering from traumatic brain injury (TBI) may result in a delayed management and neurosurgical intervention, which is potentially detrimental. The aim of this study was to study the effect of triaging and delayed transfers on outcome, specifically studying time to diagnostics and neurosurgical management. Methods: This was a retrospective observational cohort study of TBI patients in need of neurosurgical care, 15 years and older, in the Stockholm Region, Sweden, from 2008 throughout 2014. Data were collected from pre-hospital and in-hospital charts. Known TBI outcome predictors, including the protein biomarker of brain injury S100B, were used to assess injury severity. Characteristics and outcomes of direct trauma center (TC) and those of secondary transfers were evaluated and compared. Functional outcome, using the Glasgow Outcome Scale, was assessed in survivors at 6-12 months after trauma. Regression models, including propensity score balanced models, were used for endpoint assessment. Results: A total of n = 457 TBI patients were included; n = 320 (70%) patients were direct TC transfers, whereas n = 137 (30%) were secondary referrals. In all, n = 295 required neurosurgery for the first 24 h after trauma (about 75% of each subgroup). Direct TC transfers were more severely injured (median Glasgow Coma Scale 8 vs. 13) and more often suffered a high energy trauma (31 vs. 2.9%) than secondary referrals. Admission S100B was higher in the TC transfer group, though S100B levels 12-36 h after trauma were similar between cohorts. Direct or indirect TC transfer could be predicted using propensity scoring. The secondary referrals had a shorter distance to the primary hospital, but had later radiology and surgery than the TC group (all p < 0.001). In adjusted multivariable analyses with and without propensity matching, direct or secondary transfers were not found to be significantly related to outcome. Time from trauma to surgery did not affect outcome. Conclusions: TBI patients secondary transported to a TC had surgical intervention performed hours later, though this did not affect outcome, presumably demonstrating that accurate pre-hospital triaging was performed. This indicates that for selected patients, a wait-and-see approach with delayed neurosurgical intervention is not necessarily detrimental, but warrants further research.
RESUMEN
BACKGROUND: Prehospital intubation in traumatic brain injury (TBI) focuses on limiting the effects of secondary insults such as hypoxia, but no indisputable evidence has been presented that it is beneficial for outcome. The aim of this study was to explore the characteristics of patients who undergo prehospital intubation and, in turn, if these parameters affect outcome. MATERIAL AND METHODS: Patients ≥15 years admitted to the Department of Neurosurgery, Stockholm, Sweden with TBI from 2008 through 2014 were included. Data were extracted from prehospital and hospital charts, including prospectively collected Glasgow Outcome Score (GOS) after 12 months. Univariate and multivariable logistic regression models were employed to examine parameters independently correlated to prehospital intubation and outcome. RESULTS: A total of 458 patients were included (n = 178 unconscious, among them, n = 61 intubated). Multivariable analyses indicated that high energy trauma, prehospital hypotension, pupil unresponsiveness, mode of transportation, and distance to the hospital were independently correlated with intubation, and among them, only pupil responsiveness was independently associated with outcome. Prehospital intubation did not add independent information in a step-up model versus GOS (p = 0.154). Prehospital reports revealed that hypoxia was not the primary cause of prehospital intubation, and that the procedure did not improve oxygen saturation during transport, while an increasing distance from the hospital increased the intubation frequency. CONCLUSION: In this modern trauma cohort, prehospital intubation was not independently associated with outcome; however, hypoxia was not a common reason for prehospital intubation. Prospective trials to assess efficacy of prehospital airway intubation will be difficult due to logistical and ethical considerations.
RESUMEN
BACKGROUND: Best evidence guidelines are intended to standardise assessment and treatment of patients with head trauma and improve outcomes for TBI patients. The primary aim was to explore pre-hospital emergency care nurses' (PECNs') documented assessment and care of patients with head trauma and the secondary aim to study gender differences in the documented care and interventions given by the PECNs. METHODS: A retrospective observational study was conducted by evaluating 2750 prehospital medical records. RESULTS: The results showed that 25.2% of the patients were assessed according to all four core-elements in the guidelines and 78.6% of the patients underwent at least one intervention by the PECNs. Male patients were to a higher extent assessed according to guidelines and were given higher transport priority while females were more often assessed for vital parameters and received significantly more analgesics. The assessment documented by the PECNs was not optimal concerning documentation using the Glasgow Coma Scale, but the documented assessment of circulation and, especially, respiratory rate was high (77.2%) compared to previous studies. CONCLUSION: The findings of this study showed a low degree of documented assessment of parameters related to head trauma and might also indicate some gender differences in the assessment and management.

BACKGROUND: Trauma systems and regionalized trauma care have been shown to improve outcome in severely injured trauma patients. The aim of this study was to evaluate the implementation of a prehospital trauma care protocol and transport directive, and to determine its effects on the number of primary admissions and secondary trauma transfers in a large Scandinavian city. METHODS: We performed a retrospective observational study based on local trauma registries and hospital and ambulance records in Stockholm County; patients > 15 years of age with an Injury Severity Score (ISS) > 15 transported to any emergency care hospitals in the Stockholm area were included for the years 2006 and 2008. We also included secondary transferred patients to the regional trauma center during 2006, 2008, and 2013. RESULTS: A total of 693 primarily admitted trauma patients were included for the years 2006 and 2008. For the years 2006, 2008 and 2013, we included 114 secondarily transported trauma patients. The number of primary patient transports to the trauma center increased during the years by 20.2%, (p < 0.001); patients primarily transported to the trauma center had a significantly higher Injury Severity Score in 2008 than in 2006, and the number of patients transported secondarily to the trauma center in 2006 was higher compared to 2008 and to 2013 (p < 0.001, all 3 years). DISCUSSION: Our data indicate that implementation of a prehospital trauma care protocol may have an effect on transportation of severely injured trauma patients. A decrease in secondarily transported trauma patients to the regional trauma center was noted after 1 year and persisted at 7 years after the organizational change. Patients primarily admitted to the trauma center after the change had more severe injuries than patients transported to other emergency hospitals in the area even if 20 % of patients were not admitted primarily to a trauma center. This does not imply that the transport directives or the criteria were not followed but rather reveals the difficulties and uncertainties of field triage. CONCLUSIONS: With the introduction of a prehospital trauma transport directive in a large urban city, an increase in patients transported to the regional trauma center and a decrease in secondary transfers were detected, but a considerable number of severely injured patients were still transported to local hospitals.

BACKGROUND: Trauma-related mortality can be lowered by efficient prehospital care. Less is known about whether gender influences the prehospital trauma care provided. The aim of this study was to explore gender-related differences in prehospital trauma care of severely injured trauma patients, with a special focus on triage, transportation, and interventions. METHODS: We performed a retrospective observational study based on local trauma registries and hospital and ambulance records in Stockholm County, Sweden. A total of 383 trauma patients (279 males and 104 females) > 15 years of age with an Injury Severity Score (ISS) of > 15 transported to emergency care hospitals in the Stockholm area were included. RESULTS: Male patients had a 2.75 higher odds ratio (95 % CI, 1.2-6.2) for receiving the highest prehospital priority compared to females on controlling for injury mechanism and vital signs on scene. No significant difference between genders was detected regarding other aspects of the prehospital care provided. CONCLUSIONS: This study indicated that prehospital prioritization among severely injured late adolescent and adult trauma patients differs between genders. Knowledge of a more diffuse presentation of symptoms in female trauma patients despite severe injury may help to adapt and improve prehospital trauma care for this group.
