- Objectives: To explore the type and frequency of activities and multitasking performed by emergency department clinicians.Methods: Eighteen clinicians (licensed practical nurses, registered nurses and medical doctors), six from each occupational group, at two Swedish emergency departments were followed in their clinical work for 2 h each to observe all their activities and multitasking practices. Data were analysed using qualitative and quantitative content analysis.Results: Fifteen categories of activities could be identified based on 1882 observed activities during the 36 h of observation. The most common activity was information exchange, which was most often performed face-to-face. This activity represented 42.1% of the total number of observed activities. Information exchange was also the most common activity to be multitasked. Registered nurses performed most activities and their activities were multitasked more than the other clinicians. The nurses’ and doctors’ offices were the most common locations for multitasking in the emergency department.Conclusion: This study provides new knowledge regarding the activities conducted by clinicians in the emergency department. The most frequent activity was information exchange, which was the activity most often performed by the clinicians when multitasking occurred. Differences between clinicians were found for activities performed and multitasked, with registered nurses showing the highest frequencies for both.

- OBJECTIVES: Oxygen (O2) is a cornerstone in the treatment of critically ill patients, and the guidelines prescribe 10-15 l of O2/min even to those who are initially normoxic. Studies using indirect or invasive methods suggest, however, that supplemental O2 may have negative cardiovascular effects. The aim of this study was to test the hypothesis, using noninvasive cardiac magnetic resonance imaging, that inhaled supplemental O2 decreases cardiac output (CO) and coronary blood flow in healthy individuals. METHODS: Sixteen healthy individuals inhaled O2 at 1, 8 and 15 l/min through a standard reservoir bag mask. A 1.5 T magnetic resonance imaging scanner was used to measure stroke volume, CO and coronary sinus blood flow. Left ventricular (LV) perfusion was calculated as coronary sinus blood flow/LV mass. RESULTS: The O2 response was dose-dependent. At 15 l of O2/min, blood partial pressure of O2 increased from an average 11.7 to 51.0 kPa with no significant changes in blood partial pressure of CO2 or arterial blood pressure. At the same dose, LV perfusion decreased by 23% (P=0.005) and CO decreased by 10% (P=0.003) owing to a decrease in heart rate (by 9%, P<0.002), with no significant changes in stroke volume or LV dimensions. Owing to the decreased CO and LV perfusion, systemic and coronary O2 delivery fell by 4 and 11% at 8 l of O2/min, despite the increased blood oxygen content. CONCLUSION: Our data indicate that O2 administration decreases CO, LV perfusion and systemic and coronary O2 delivery in healthy individuals. Further research should address the effects of O2 therapy in normoxic patients.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The 2011 European Society of Cardiology guidelines state that acute coronary syndrome (ACS) may be excluded with a rapid 3 h high-sensitivity troponin T (HsTnT) sampling protocol. We aimed to evaluate the diagnostic and prognostic performance of HsTnT in patients with chest pain admitted with possible ACS in routine care. METHODS: A total of 773 consecutive patients admitted for in-hospital care for chest pain suspicious of ACS were included retrospectively. HsTnT values at admission and at 3-4 and 6-7 h were analysed for diagnostic performance. In addition, prognostic performance towards a combined 60-day endpoint of ACS, nonelective revascularization or death of all causes was studied. RESULTS: Twenty-three per cent of the patients had ACS during the hospital stay and 1.6% had an endpoint after discharge but within 60 days. The sensitivity of HsTnT for ACS at admission, 3-4 and 6-7 h was only 68, 79 and 81%, respectively. Sensitivity and negative predictive value for acute myocardial infarction alone were 80 and 93% on admission and 97 and 99% at 3-4 h. Among patients aged 75 years and older, 63% had a positive HsTnT on admission, but only 39% of these had an ACS during hospital stay. CONCLUSION: Our data confirm that prolonged testing with HsTnT after 3-4 h does not improve diagnostic performance for ACS. However, although sensitivity for acute myocardial infarction was very good, sensitivity for ACS was insufficient to rule out ACS even at 6-7 h. Less than half of all recorded positive HsTnT were true positives. On the basis of these results, we find it unlikely that HsTnT has improved the diagnosis of ACS in the emergency care setting.

- OBJECTIVES: Virtual reality systems may allow for organized study of mass casualty triage systems by allowing investigators to replicate the same mass casualty incident, with the same victims, for a large number of rescuers. The study objectives were to develop such a virtual reality system, and use it to assess the ability of trained paramedic students to triage simulated victims using two triage systems.METHODS: Investigators created 25 patient scenarios for a highway bus crash in a virtual reality simulation system. Paramedic students were trained to proficiency on the new 'Sort, Assess, Life saving interventions, Treat and Transport (SALT)' triage system, and 22 students ran the simulation, applying the SALT algorithm to each victim. After a 3-month washout period, the students were retrained on the 'Smart' triage system, and each student ran the same crash simulation using the Smart system. Data inputs were recorded by the simulation software and analyzed with the paired t-tests.RESULTS: The students had a mean triage accuracy of 70.0% with SALT versus 93.0% with Smart (P=0.0001). Mean overtriage was 6.8% with SALT versus 1.8% with Smart (P=0.0015), and mean undertriage was 23.2% with SALT versus 5.1% with Smart (P=0.0001). The average time for a student to triage the scene was 21 min 3 s for SALT versus 11 min 59 s for Smart (P=0.0001).CONCLUSION: The virtual reality platform seems to be a viable research tool for examining mass casualty triage. A small sample of trained paramedic students using the virtual reality system was able to triage simulated patients faster and with greater accuracy with 'Smart' triage than with 'SALT' triage.

- OBJECTIVEThe aim was to elucidate if, by strictly applying the Adaptive Process Triage (ADAPT) scale, the interrater agreement increased among the participating registered nurses (RNs) than when triaging according to the older scale, which allowed subjective interpretations of signs and symptoms. METHODSNineteen patient scenarios were triaged in 2006 by 45 RNs using the previous triage scale, and in 2008 by 30 RNs using ADAPT. RESULTSThere was no significant difference (P=0.65) between the two triage scales with regard to level of overall exact agreement (κ value 0.529 vs. 0.472). The same triage level was more often chosen when using the ADAPT system as compared to the earlier triage scale and dispersion across the triage levels was also reduced when using ADAPT. Eight (42%) of the patient scenarios were triaged as both unstable and stable by ADAPT, and 11 (58%) when the older scale was applied. Fourteen (74%) of the scenarios could not be allocated to a defined triage level by ADAPT. Five main reasons for such triage decisions were identified. CONCLUSIONBoth the triage scales showed moderate overall agreements, while dispersion of triage decisions across several triage levels declined when ADAPT was used. Although the algorithm for acuity allocation by ADAPT seemed well defined, many patient scenarios were triaged as both unstable and stable and thus allocated to various triage levels. If ADAPT is to function as a safe triage tool with low interrater variability, further revision of the triage algorithms is needed.

- OBJECTIVESTo investigate whether patients came directly to the emergency department (ED) or whether they had taken any other actions or activities within the healthcare system before attending the ED. An additional aim was to increase our understanding of the potential determinants between patients’ ED-seeking behaviour and patient-related data. METHODSThis prospective descriptive study was carried out at the ED at a level one trauma centre at a university hospital in Sweden. During 12 weeks in 2008, a 20-item study-specific questionnaire was distributed by research assistants to patients arriving either by their own means or by ambulance to the ED. In addition, patient-specific data were gathered from the electronic patient records. RESULTSA total of 2014 patients participated in the study, of whom 1192 (59%) reported to have carried out healthcare-related actions or activities before their visit to the ED. A general practitioner was the most common (29.1%) healthcare provider to have been in contact with. Female patients and patients with a longer duration of symptoms sought other health caregivers before the ED visit to a significantly higher extent (P<0.001, 0.003). Other caregivers’ referral rate to the ED was 60.1–87.9%. Accessibility to other caregivers was generally rated as easy. CONCLUSIONA large proportion of ED patients sought previous healthcare before seeking care at the ED. Female patients and patients with longer symptom duration more often sought other caregivers before seeking ED care.

- OBJECTIVES: In accidental hypothermia, normal signs of death are unreliable. It is generally accepted that a lifeless person is beyond the limits of rescue if plasma potassium (P-potassium) is higher than10 mmol/l. However, the rate of increase in potassium or in other markers after cardiac arrest has not been carefully studied in hypothermic individuals. The aim of this animal study was to assess biochemical changes after anoxic circulatory arrest at hypothermia and at normothermia followed by external cooling. METHODS: Five pigs were treated with heparin and extracorporeal circulation and cooled to 20 degrees C (primary hypothermia group). The animals were weaned from extracorporeal circulation, suffered cardiac arrest, and were cooled externally with ice to mimic victims found in a cold environment. With the use of intermittent external cardiac compressions mixing the blood, arterial P-potassium was followed after cardiac arrest until the level exceeded 10 mmol/l. Another group of five pigs (anoxic cardiac arrest group) were treated with heparin and killed by anoxia at normothermia and were thereafter treated and followed similarly to the primary hypothermia group. RESULTS: In primary hypothermia P-potassium exceeded 10 mmol/l after median 3.5 h, whereas in anoxic cardiac arrest P-potassium exceeded 10 mmol/l after median 1 h. CONCLUSION: This study shows that if cardiac arrest occurs before hypothermia is established, P-potassium increases quickly in contrast to the situation when hypothermia induces cardiac arrest. Thus, a low P-potassium in a hypothermic individual with cardiac arrest indicates that cardiac arrest occurred recently or was secondary to the hypothermic event.

- Objective: Despite an increase in research, there is still a lack of knowledge about patient safety in emergency departments (EDs) in many European countries. The aim of this study was therefore to describe the incidence and types of reported medical errors and complaints in ED care in Sweden.Methods: Data reported in 2009 were gathered from national authorities, including the National Board of Health and Welfare, the Medical Responsibility Board, the Patients Advisory Committees, and local incident-reporting systems. Data were analyzed by content analysis.Results: Among 428 cases reported by care providers to the National Board of Health and Welfare, 64 (15.0%) were related to ED care. As several cases contained more than one medical error, 92 errors were identified, out of which 39 (42.4%) were related to diagnostic procedures. Among the 4628 cases of complaints reported by patients to the Medical Responsibility Board, 306 (6.6%) were related to ED care. In total, 437 complaints regarding perceived medical errors were identified (several cases contained more than one error), with 189 (43.2%) pertaining to diagnostic procedures. A total of 1341 complaints about ED care were made by patients to the Patients Advisory Committees (n=21), of which 655 (48.8%) were related to care and treatment. There were 7434 medical errors reported to local incident-reporting systems at the EDs (n=45). Of these, 1450 (19.5%) referred to care and treatment.Conclusion: Medical errors and complaints at Swedish EDs, as reported by both patients and care providers, were related mainly to diagnostic procedures and treatments.
