- OBJECTIVE: The objective of this study was to assess the value of prehospital measurement of lactate level in blood for diagnosis of seizures in cases of transient loss of consciousness.METHODS: Between March 2018 and September 2019, prehospital lactate was measured with a point-of-care device by the emergency medical services in an area serving a population of 900 000. A total of 383 cases of transient loss of consciousness were identified and categorized as tonic-clonic seizure (TCS), other seizure, syncope, or other cause, according to the final diagnosis in the electronic medical records system. Receiver operating characteristic curve analyses were used to identify the optimal lactate cut-off.RESULTS: A total of 383 cases were included (135 TCS, 42 other seizure, 163 syncope, and 43 other causes). The median lactate level in TCS was 7.0 mmol/L, compared to a median of 2.0 mmol/L in all other cases (P < .001). The area under the curve (AUC) of TCS vs nonepileptic causes was 0.87 (95% confidence interval [CI] 0.83-0.91). The optimal cut-off (Youden index, 67.8%) was 4.75 mmol/L, with 79% sensitivity (95% CI 71-85) and 89% specificity (95% CI 85-93) for TCS.SIGNIFICANCE: Prehospital lactate can be a valuable tool for identifying seizures in transient loss of consciousness. For acceptable specificity, a higher cut-off than that previously demonstrated for hospital-based measurements must be used when values obtained close to the time of the event are interpreted.

- The importance of bystander cardiopulmonary resuscitation (CPR) prior to arrival of the emergency medical service is well documented. In Sweden, CPR is initiated prior to emergency medical services (EMS) arrival in about 30% of cardiac arrests out-of-hospital, a figure which should be improved urgently. To do so, it is of interest to know more about the bystanders' perceptions of their intervention. A qualitative method inspired by the phenomenographic approach was applied to 19 bystanders who had performed CPR. In the analysis, five main categories and 14 subcategories emerged. The main categories were: to have a sense of humanity, to have competence, to feel an obligation, to have courage and to feel exposed. Interviews described how humanity and concern for another human being were the foundation of their intervention. CPR training offers the possibility to give appropriate help in this emergency. If the aim of CPR training was extended beyond teaching the skill of CPR to include preparation of the rescuer for the intervention and his/her reactions, this might increase the number of people able to take action in the cardiac arrest situation.

- BackgroundEmergency medical services (EMS) personnel must rapidly assess and transport patients with time-sensitive conditions to optimise patient outcomes. Serum lactate, a valuable in-hospital biomarker, has become more accessible in EMS settings through point-of-care (POC) testing. Although POC lactate levels are valuable in specific patient groups, its broader application in EMS remains unclear. This study assessed the additional predictive value of POC lactate levels in a general adult EMS population.MethodsThis prospective observational study (March 2018 to September 2019) involved two EMS organisations in Västra Götaland, Sweden. Patients were triaged using the Rapid Triage and Treatment System (RETTS). POC lactate levels were measured using StatStrip Xpress devices. Non-consecutive patients who received EMS and were aged 18 years and above were available for inclusion if triaged into RETTS levels: red, orange, yellow, or green if respiratory rate of ≥ 22 breaths/min. Outcomes were adverse outcomes, including a time-sensitive diagnosis, sequential organ failure assessment (SOFA) score ≥ 2, and 30-day mortality. Statistical analyses included descriptive statistics, imputation, and regression models to assess the impact of the addition of POC lactate levels to a base model (comprising patient age, sex, presence of past medical conditions, vital signs, pain, EMS response time, assessed triage condition, and triage level) and a RETTS triage model.ResultsOf 4,546 patients (median age 75 [57, 84] years; 49% male), 32.4% had time-sensitive conditions, 12.5% met the SOFA criteria, and 7.4% experienced 30-day mortality. The median POC lactate level was 1.7 (1.2, 2.5) mmol/L. Patients with time-sensitive conditions had higher lactate levels (1.9 mmol/L) than those with non-time-sensitive conditions (1.6 mmol/L). The probability of a time-sensitive condition increased with increasing lactate level. The addition of POC lactate marginally enhanced the predictive models, with a 1.5% and 4% increase for the base and RETTS triage models, respectively. POC lactate level as a sole predictor showed chance-only level predictive performance.ConclusionsPrehospital POC lactate assessment provided limited additional predictive value in a general adult EMS population. However, it may be beneficial in specific patient subgroups, emphasizing the need for its judicious use in prehospital settings.

- Background: A large proportion of patients who call 112 in Sweden do so because of pain. The purpose of this study was to compare three of the most common types of pain presented by the patients: chest pain, abdominal pain and hip injury, in terms of initial assessment, intensity, treatment and effect of treatment. The overall rationale was to evaluate whether the early assessment and treatment of pain in the pre-hospital setting is optimal or whether there is room for improvement.Methods: Observational study during 2016 including 1234 patients triaged to chest pain, abdominal pain and hip injury by the Emergency Medical Services (EMS) in Gothenburg, Sweden.Results: Severe pain on the arrival of the EMS was described by 39% of patients with a hip injury, 27% with abdominal pain and 15% with chest pain. Analgesics were given to 58% of patients with a hip injury, 35% with chest pain and 34% with abdominal pain. A lower intensity of pain at re-evaluation was observed in 80% of patients with a hip injury, 57% with chest pain and 43% with abdominal pain. Administration of analgesics increased with the duration of pre-hospital care time in all three groups.Conclusions: Patients with a hip injury had the most severe pain and they received most pain-relieving medication. Overall, a relatively small proportion of patients with pain received pain-relieving medication and there appears to be an extensive room for improvement.

- Background: Patients who call for an ambulance but only have primary care needs do not always get appropriate care. The starting point in this study is that such patients should be assigned to as basic of care as possible, while maintaining high levels of patient trust and patient safety.Aim: To evaluate patient trust and patient safety among low-priority ambulance patients referred to care at either the Community Health Centre (CHC) or the Emergency Department (ED).Methods: This randomized controlled trial pilot study compared the level of patient trust and patient safety among low-priority ambulance patients who were randomized into two groups: CHC (n = 105) or ED (n = 83).Results: There was a high level of trust in the care received, regardless of whether the patient received care at CHC or ED. Overall 31% fulfilled one or more of the given criteria for potentially jeopardizing patient safety.Conclusion: Patient selection for the trial indicated a potential limit in patient safety. There was a high level of trust in the care received regardless of whether the patient received care. The accuracy of patient selection for the new care model needs to be further improved with the intention to enhance patient safety even further.

- Purpose: Patients must be able to feel as much trust for caregivers and the healthcare system at the healthcare centre as at the emergency department. The aim of this study is to explain and understand the phenomenon of trust in the early chain of healthcare, when a patient has called an ambulance for non-urgent condition and been referred to the healthcare centre.Method: A lifeworld hermeneutic approach from the perspective of caring science was used. Ten patient participated: seven female and three male. The setting is the early chain of healthcare in south-wetern Sweden.Results: The findings show that the phenomenon of trust does not automatically involve medical care. However, attention to the patient's lifeworld in a professional caring relationship enables the patient to trust the caregiver and the healthcare environment. It is clear that the "voice of lifeworld" enables the patient to feel trust.Conclusion: Trust in the early chain of healthcare entails caregivers' ability to play attention to both medical and existentioal issues in compliance with the patient's information and questions. Thus, the patient must be invited to participate in assessment and decisions concerning his or her own healthcare, in a credible manner and using everyday language.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Pain management needs to be comprehensively investigated in patients with hip fractures, as it represents a fast-growing challenge to emergency care. The purpose of this study was to describe reported pain in patients with suspected hip fractures in a prehospital setting.METHODS: In this observational study, 1,426 patients with a suspected hip fracture were included. Dynamic and static pain were assessed on the arrival of the emergency medical services (EMS) and on hospital admission using the Numerical Rating Scale (NRS), if feasible, and the Behaviour Rating Scale (BRS), if not.RESULTS: On EMS arrival, the median dynamic NRS pain score was eight and 84% of the patients had severe or moderate dynamic pain according to the BRS. On admission to hospital, the median dynamic NRS pain score was reduced to five and 45% of the patients had reduced dynamic pain according to the BRS. Among all patients, the NRS was judged to be feasible and was therefore used in 36%. Furthermore, there was an association between the decrease in pain and the increase in the number of administered medications, as well as the duration of prehospital care.CONCLUSIONS: Patients with suspected hip fractures suffered substantial pain on EMS arrival. Only half experienced a reduction in pain on hospital admission and only 75% received pain-relieving medication.

- Background Impaired cognition is a major risk factor for perioperative delirium. It is essential to provide good pain control in patients with hip fractures and especially important in patients with severely impaired cognitive status, as they receive less pain medication, have poorer mobility, poorer quality of life and higher mortality than patients with intact cognition. The purpose of this study was to examine the association between preoperative pain management with nerve blocks and cognitive status in patients with hip fractures during the perioperative period. Methods One hundred and twenty-seven patients with hip fractures participating in a double-blind, randomised, controlled trial were included in this study. At hospital admission, a low-dose fascia iliaca compartment block (FICB) was administered as a supplement to regular analgesia. Cognitive status was registered on arrival at hospital before FICB and on the first postoperative day using the Short Portable Mental Status Questionnaire. Results Changes in cognitive status from arrival at hospital to the first postoperative day showed a positive, albeit not significant, trend in favour of the intervention group. The results also showed that patients with no or a moderate cognitive impairment received 50% more prehospital pain medication than patients with a severe cognitive impairment. FICB was well tolerated in patients with hip fractures. Conclusion Fascia iliaca compartment block given to patients with hip fractures did not affect cognitive status in this study. Patients with a cognitive impairment may receive inadequate pain relief after hip fracture and this discrimination needs to be addressed in further studies.

Tidskriftsartikel (refereegranskat)abstract
- Background Older persons with a suspected hip fracture and suffering considerable pain are common patients in the emergency medical services (EMS). Pain treatment needs to be improved and fascia iliaca compartment block (FICB) can be one option. The purpose of this paper was to analyse prehospital pain in patients with a suspected hip fracture under EMS care and to compare standard treatment and FICB. Methods An evaluation of a retrospective case-control study comprising 135 patients from a pilot project with FICB in an EMS organisation in Sweden. The control patients were matched with FICB patients. Pain was assessed on the arrival of the EMS and on arrival in hospital. Results In all, 27 patients received FICB and 108 had standard pain treatment. There was a significant reduction in pain in both groups. However, there was a more marked reduction in pain among patients who received FICB than in the control group. So, for static pain, 56% experienced a reduction in pain in the FICB group versus 30% among controls (p < 0.01). The corresponding values for dynamic pain were 85% and 59% (p < 0.01). Conclusion FICB can be a good supplement to standard prehospital pain treatment in patients with suspected hip fractures.
