- INTRODUCTION: Acute chest pain is a common symptom among prehospital emergency care patients. Therefore, it is crucial that ambulance nurses (ANs) have the ability to identify symptoms and assess patients suffering from acute coronary syndrome (ACS). The aim of this study is to explore the occurrence of dyspnoea and nausea and/or vomiting in the prehospital phase of a suspected ACS and the associations with patients' outcome.METHODS: This study has a quantitative design based on data from hospital records and from a previous interventional study (randomised controlled trial) including five Emergency Medical Service (EMS) systems in western Sweden in the years 2008-2010.RESULTS: In all, 1836 patients were included in the interventional study. Dyspnoea was reported in 38% and nausea and/or vomiting in 26% of patients. The risk of death within one year increased with the presence of dyspnoea. The presence of nausea and/or vomiting increased the likelihood of a final diagnosis of acute myocardial infarction (AMI).CONCLUSION: This study shows that dyspnoea, nausea and/or vomiting increase the risk of death and serious diagnosis among ACS patients. This means that dyspnoea, nausea and/or vomiting should influence the ANs' assessment and that special education in cardiovascular nursing is required.

- ObjectivesWe compare various aspects in the early chain of care among patients with haemorrhagic stroke and ischaemic stroke. Materials & methodsThe Emergency Medical Services (EMS) and nine emergency hospitals, each with a stroke unit, were included. All patients hospitalised with a first and a final diagnosis of stroke between 15 December 2010 and 15 April 2011 were included. The primary endpoint was the system delay (from call to the EMS until diagnosis). Secondary endpoints were: (i) use of the EMS, (ii) delay from symptom onset until call to the EMS; (iii) priority at the dispatch centre; (iv) priority by the EMS; and (v) suspicion of stroke by the EMS nurse and physician on admission to hospital. ResultsOf 1336 patients, 172 (13%) had a haemorrhagic stroke. The delay from call to the EMS until diagnosis was significantly shorter in haemorrhagic stroke. The patient's decision time was significantly shorter in haemorrhagic stroke. The priority level at the dispatch centre did not differ between the two groups, whereas the EMS nurse gave a significantly higher priority to patients with haemorrhage. There was no significant difference between groups with regard to the suspicion of stroke either by the EMS nurse or by the physician on admission to hospital. ConclusionsPatients with a haemorrhagic stroke differed from other stroke patients with a more frequent and rapid activation of EMS.

- Background Symptoms related to stroke diverge and may mimic many other conditions. Aims To evaluate clinical findings among patients with a clinical suspicion of stroke in a prehospital setting and find independent predictors of a final diagnosis of stroke or transient ischemic attack (TIA). Methods An observational multicenter study includes nine emergency hospitals in western Sweden. All patients transported to hospital by ambulance and in whom a suspicion of stroke was raised by the emergency medical service clinician before hospital admission during a four-month period were included. Results Of 1081 patients, a diagnosis of stroke was confirmed at hospital in 680 patients (63%), while 69 (6%) were diagnosed as TIA and 332 patients (31%) received other final diagnoses. In a multiple logistic regression analysis, factors independently associated with a final diagnosis of stroke or TIA were increasing age, odds ratio (OR) per year: 1.02, P = 0.007, a history of myocardial infarction (OR: 1.77, P = 0.01), facial droop (OR: 2.81, P < 0.0001), arm weakness (OR: 2.61, P < 0.0001), speech disturbance (OR: 1.92, P < 0.0001), and high systolic blood pressure (OR: 1.50, P = 0.02), while low oxygen saturation was significantly associated with other diagnoses (OR: 0.41, P = 0.007). More than half of all patients among patients with both stroke/TIA and other final diagnoses died during the five-year follow-up. Conclusions Seven factors including the three symptoms included in the Face Arm Speech Test were significantly associated with a final diagnosis of stroke or TIA in a prehospital assessment of patients with a suspected stroke.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: In acute stroke, the risk of death and neurological sequelae are obvious threats. The aim of the study was to evaluate the association between various clinical factors identified by the emergency medical service (EMS) system before arriving at hospital and the risk of death during the subsequent year among patients with a confirmed stroke. Material and Methods: All patients with a diagnosis of stroke as the primary diagnosis admitted to a hospital in western Sweden (1.6 million inhabitants) during a four-month period were included. There were no exclusion criteria. Results: In all, 1,028 patients with a confirmed diagnosis of stroke who used the EMS were included in the analyses. Among these patients, 360 (35%) died during the following year. Factors that were independently associated with an increased risk of death were as follows: (1) high age, per year OR 1.07; 95% CI 1.05-1.09; (2) a history of heart failure, OR 2.08; 95% CI 1.26-3.42; (3) an oxygen saturation of < 90%, OR 8.05; 95% CI 3.33-22.64; and (4) a decreased level of consciousness, OR 2.19; 95% CI 1.61-3.03. Conclusions: Among patients with a stroke, four factors identified before arrival at hospital were associated with a risk of death during the following year. They were reflected in the patients' age, previous clinical history, respiratory function, and the function of the central nervous system.

Tidskriftsartikel (refereegranskat)abstract
- The two major complications of atherosclerosis are acute myocardial infarction (AMI) and acute ischemic stroke. Both are life-threatening conditions characterised by the abrupt cessation of blood flow to respective organs, resulting in an infarction. Depending on the extent of the infarction, loss of organ function varies considerably. In both conditions, it is possible to limit the extent of infarction with early intervention. In both conditions, minutes count. This article aims to describe differences and similarities with regard to the way patients, bystanders and health care providers act in the acute phase of the two diseases with the emphasis on the pre-hospital phase.

- Background Many patients who suffer from acute chest pain are transported by ambulance. It is not known how often treatment prior to hospital admission is optimal and how optimal pain-relieving treatment is defined. It is often difficult to delineate pain from anxiety. Aim To describe various aspects of chest pain in the pre-hospital setting with the emphasis on a) treatment and b) presumed acute coronary syndrome. Methods In the literature search, we used PubMed and the appropriate key words. We included randomised clinical trials and observational studies. Results Four types of drug appear to be preferred: 1) narcotic analgesics, 2) nitrates, 3) beta-blockers and 4) benzodiazepines. Among narcotic analgesics, morphine has been associated with the relief of pain at the expense of side-effects. Alfentanil was reported to produce more rapid pain relief. Nitrates have been associated with the relief of pain with few side-effects. Beta-blockers have been reported to increase the relief of pain when added to morphine. The combination of beta-blockers and morphine has been reported to be as effective as beta-blockers alone in pain relief, but this combination therapy was associated with more side-effects. Experience from anxiety-relieving drugs such as benzodiazepines is limited. It is not known how these 4 drugs should be combined. The results indicate that various pain-relieving treatments might modify the disease. Conclusion Our knowledge of the optimal treatment of chest pain and associated anxiety in the pre-hospital setting is insufficient. Recommendations from existing guidelines are limited. Large randomised clinical trials are warranted.

Prehospital akutsjukvård: ett potentiellt forskarutbildningsämne : populärvetenskaplig rapport från de första 82 doktorsavhandlingarna i Sverige
- 2022
-
Rapport (populärvet., debatt m.m.)abstract
- Syfte: Att beskriva prehospital akutsjukvård som ett potentiellt forskarutbildningsämne utifrån avhandlingar som skrivits och försvarats i Sverige inom detta kunskapsområde.Metod: Systematisk och manuell sökning har gjorts via MEDLINE (PubMed) och kontakt med lärosäten.Resultat: Totalt har 80 doktorsavhandlingar och två licentiatavhandlingar identifierats inom kunskapsområdet prehospital akutsjukvård. Avhandlingarna har försvarats under tidsperioden 1982–2021. Produktiviteten har succesivt ökat med 31 avhandlingar som försvarats under den senaste femårsperioden. Flest avhandlingar har skrivits vid Göteborgs Universitet (n=27) Karolinska Institutet (n=22) och Umeå Universitet (n=9). Avhandlingarna har skrivits av 51 sjuksköterskor, 28 läkare, en statistiker, en socionom, en präst och en folkhälsovetare (en avhandling redovisade två professioner; sjuksköterska och läkare). Kvinnor har varit författare i 48%. Avhandlingarna har delats in i följande övergripande kunskapsområden med i några fall även tillhörande undergrupper: A. Akut sjukdom, A1) Prognostiska faktorer (n=25) samt A2) Patient och anhörigperspektiv (n=8); B. Katastrof (n=6); C. Etik och värderingar (n=3); D. Vård- och arbetsmiljö (n=2); E. Kompetens, lärande och utbildning, E1) Ambulanssjuksköterska (n=5) samt E2) Hjärt-lungräddning (n=2 ); F. Trauma och smärta, F1) Skador och räddning (n=4 ), F2) Smärta (n=1) samt F3) Hypotermi (n=4); G. Akuta vårdprocesser och prioritering, G1) Resursutnyttjande (n=1) samt G2) Larmcentral och samverkan (n=8); H. Vårdande bedömning och beslut, H1) Vårdande förhållningssätt (n=3), H2) Diagnostisk bedömning och beslutsstöd (n=6) samt H3) Identifikation av sjukdom och vårdnivå (n=4).Konklusion: Antalet doktorsavhandlingar inom prehospital akutsjukvård är i ökande. Majoriteten av författarna är sjuksköterskor. Avhandlingarna täcker ett brett spektrum av kunskapsområden, men prognostiska faktorer vid Akut sjukdom är dominerande. Könsfördelningen är acceptabel. Patient- och anhörigperspektivet är sparsamt belyst liksom vissa patientgrupper, t.ex. infektioner och trauma. Forskningen inom kunskapsområdet inleddes med fokus på överlevnad vid hjärtstopp utanför sjukhus. Under åren har forskningsområdet vidgats till allt bredare problemområden; vård på rätt vårdnivå är ett sådant exempel.

- BackgroundSepsis is a life-threatening condition where the risk of death has been reported to be even higher than that associated with the major complications of atherosclerosis, i.e. myocardial infarction and stroke. In all three conditions, early treatment could limit organ dysfunction and thereby improve the prognosis.AimTo describe what has been published in the literature a/ with regard to the association between delay until start of treatment and outcome in sepsis with the emphasis on the pre-hospital phase and b/ to present published data and the opportunity to improve various links in the pre-hospital chain of care in sepsis.MethodsA literature search was performed on the PubMed, Embase (Ovid SP) and Cochrane Library databases.ResultsIn overall terms, we found a small number of articles (n=12 of 1,162 unique hits) which addressed the prehospital phase. For each hour of delay until the start of antibiotics, the prognosis appeared to become worse. However, there was no evidence that prehospital treatment improved the prognosis.Studies indicated that about half of the patients with severe sepsis used the emergency medical service (EMS) for transport to hospital. Patients who used the EMS experienced a shorter delay to treatment with antibiotics and the start of early goal-directed therapy (EGDT). Among EMS-transported patients, those in whom the EMS staff already suspected sepsis at the scene had a shorter delay to treatment with antibiotics and the start of EGDT.There are insufficient data on other links in the prehospital chain of care, i.e. patients, bystanders and dispatchers.ConclusionSevere sepsis is a life-threatening condition. Previous studies suggest that, with every hour of delay until the start of antibiotics, the prognosis deteriorates. About half of the patients use the EMS. We need to know more about the present situation with regard to the different links in the prehospital chain of care in sepsis.

Forskningsöversikt (refereegranskat)abstract
- HUVUDBUDSKAPÖver 100 avhandlingar har i dagsläget skrivits om den prehospitala akutsjukvården i Sverige.Dessa täcker ett omfattande kunskapsfält, allt ifrån prognostiska faktorer vid akut sjukdom till ambulans personalens psykiska och fysiska hälsa.Endast ett kunskapsområde har belysts mera om fattande, och det är hjärt–lungräddning vid plötsligt hjärtstopp.Vården av patienter med psykisk ohälsa har inte belysts i någon avhandling.Det finns stora kunskapsluckor, och vidare forskning inom området behövs.
