Evaluation of a university hospital trauma team activation protocol

<p>Abstract</p> <p>Background</p> <p>Admission with a multidisciplinary trauma team may be vital for the severely injured patient, as this facilitates rapid diagnosis and treatment. On the other hand, patients with minor injuries do not need the trauma team for adequate care. Correct triage is important for optimal resource utilization. The aim of the study was to evaluate our criteria for activating the trauma team, and identify suboptimal criteria that might be changed in the interest of precision.</p> <p>Methods</p> <p>The study is an observational, retrospective cohort-study. All patients admitted with the trauma team (n = 382), all severely injured (Injury Severity Score (ISS) >15) (n = 161), and all undergoing an emergency procedure aimed at counteracting compromised airways, respiration or circulation at our hospital (n = 142) during 2006-2007 were included. Data were recorded from the admission records and the electronic patient records. The trauma team activation protocol was evaluated against the occurrence of severe injury and the occurrence of emergency procedures.</p> <p>Results</p> <p>A total of 441 patients were included. The overtriage was 71% and undertriage 32% when evaluating against ISS >15 as the standard of reference. When occurrence of emergency procedures was held as the standard of standard of reference, the over- and undertriage was 71% and 21%, respectively. Mechanism of injury-criteria for trauma team activation contributed the most to overtriage. The emergency procedures performed were mostly endotracheal intubation and external fixation of fractures. Less than 3% needed haemostatic laparotomy or thoracotomy. Approximately 2/3 of the overtriage represented isolated head or cervical spine injuries, and/or interhospital transfers.</p> <p>Conclusions</p> <p>The over- and undertriage of our protocol are both too high. To decrease overtriage we suggest omissions and modifications of some of the criteria. To decrease undertriage, transferred patients and patients with head injuries should be more thoroughly assessed against the trauma team activation criteria.</p

Mortality after hospital admission for trauma in Norway: A retrospective observational national cohort study

Background - National quality data for trauma care in Norway have not previously been reported. We have therefore assessed crude and risk-adjusted 30-day mortality in trauma cases after primary hospital admission on national and regional levels for 36 acute care hospitals and four regional trauma centres. Methods - All patients in the Norwegian Trauma Registry in 2015–2018 were included. Crude and risk-adjusted 30-day mortality was assessed for the total cohort and for severe injuries (Injury Severity Score ≥16), and individual and combined effects of health region, hospital level, and hospital size were studied. Results - 28,415 trauma cases were included. Crude mortality was 3.1% for the total cohort and 14.5% for severe injuries, with no statistically significant difference between regions. Risk-adjusted survival was lower in acute care hospitals than in trauma centres (0.48 fewer excess survivors per 100 patients, P Conclusion - Differences in risk-adjusted survival for severe injuries can to a large extent be attributed to whether patients are directly admitted to a trauma centre. This should have implications for planning of transport capacity in remote areas

The treatment of spleen injuries: a retrospective study

Published version. Source at http://doi.org/10.1186/s13049-015-0163-6.Background Hemorrhage after blunt trauma is a major contributor to death after trauma. In the abdomen, an injured spleen is the most frequent cause of major bleeding. Splenectomy is historically the treatment of choice. In 2007, non-operative management (NOM) with splenic artery embolization (SAE) was introduced in our institution. The indication for SAE is hemodynamically stable patients with extravasation of contrast, or grade 3–5 spleen injury according to the Abbreviated Organ Injury Scale 2005, Update 2008. We wanted to examine if the introduction of SAE increased the rate of salvaged spleens in our trauma center. Method All patients discharged with the diagnosis of splenic injury in the period 01.01.2000 – 31.12.2013 from the University Hospital of North Norway Tromsø were included in the study. Patients admitted for rehabilitation purposes or with an iatrogenic injury were excluded. Results A total of 109 patients were included in the study. In the period 2000-7, 20 of 52 patients were splenectomized. During 2007-13, there were 6 splenectomies and 24 SAE among 57 patients. The reduction in splenectomies is significant (p < 0.001). There is an increase in the rate of treated patients (splenectomy and SAE) from 38 to 53 % in the two time periods, but not significantly (p = 0.65). Conclusion The rate of salvaged spleens has increased after the introduction of SAE in our center

The aim of this study was to compare the cause and rate of fatal injuries in the northernmost area of the Nordic countries over a 5-year period. Methods: In this retrospective cohort, we used the Cause of Death Registries to collate all deaths from 2007 to 2011 due to an external cause of death. The study area was the three northernmost counties in Norway, the four northernmost counties in Finland and Sweden, and the whole of Iceland. Results: A total of 4308 deaths were included in the analysis. Low energy trauma comprised 24% of deaths and high energy trauma 76% of deaths. Northern Finland had the highest incidence of both high and low energy trauma deaths. Iceland had the lowest incidence of high and low energy trauma deaths. Iceland had the lowest prehospital share of deaths (74%) and the lowest incidence of injuries leading to death in a rural location. The incidence rates for high energy trauma death were 36.1/100000/year in Northern Finland, 15.6/100000/year in Iceland, 27.0/100000/year in Northern Norway, and 23.0/100000/year in Northern Sweden. Conclusion: We found unexpected differences in the epidemiology of trauma death between the countries. The differences suggest that a comparison of the trauma care systems and preventive strategies in the four countries is required.

Accuracy of neuropathic pain measurements in patients with symptoms of polyneuropathy: validation of painDETECT, Self-Completed Leeds Assessment of Neuropathic Symptoms and Signs, and Douleur Neuropathique 4

Pain is a common symptom in patients referred to polyneuropathy assessment. Diagnostic evaluation and choice of treatment may depend on whether the pain is likely to be neuropathic or not. This study aimed to investigate the diagnostic accuracy of 3 tools commonly used to differentiate between neuropathic and nonneuropathic pain. To accomplish this, we included patients with bilateral distal lower extremity pain, referred to neurological outpatient clinics at 5 Norwegian University hospitals for polyneuropathy assessment. The patients filled in Norwegian versions of painDETECT, the Self-Completed Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS), and the clinician-rated Douleur Neuropathique 4 (DN4). All patients underwent a clinical examination and nerve conduction measurements and were classified according to the NeuPSIG neuropathic pain criteria (reference standard). In total, 729 patients were included, of which 63% had neuropathic pain by the reference standard. Only DN4 demonstrated high sensitivity (0.87), whereas all 3 tools had low specificity (≤0.65). Importantly, the tools' predictive ability was unsatisfactory; The probability of getting a correct test result was 3 quarters at best, and at worst, no better than two fifths. Consequently, we show that neither DN4, painDETECT, nor S-LANSS can be confidently used to assess neuropathic pain in a neurological outpatient population with symptoms of polyneuropathy

Aspects of the primary assessment and management of anal incontinence

Avhandlingens tittel er ”Aspects of the primary assessment and management of anal incontinence - The introduction of a new treatment”. Disputas for graden Ph.D. finner sted 05.04.2013. Ufrivillig lekkasje av luft og avføring er en relativt vanlig og belastende tilstand, og kan gi redusert livskvalitet. Det er utviklet en ny metode for å behandle denne lidelsen, som består i å injisere et rom-oppfyllende stoff i endetarmskanalen. Det sentrale målet i prosjektet har vært å vurdere om denne nye behandlingen er bedre enn eksisterende metoder. I tillegg har prosjektgruppen ønsket å utvikle metoder til å vurdere anal inkontinens bedre

This article is also available via DOI:10.1186/s13049-016-0295-3Background: Correct triage based on prehospital information contributes to a better outcome for potentially seriously injured patients. In 2011 we changed the trauma team activation (TTA) criteria in our center in order to improve the high over- and undertriage properties of the protocol. Five criteria that were unable to predict severe injury were removed. In the present study, we evaluated the protocol revision by comparing over- and undertriage in the former and present set of criteria. Methods: All severely injured patients (Injury Severity Score (ISS) > 15) and all patients admitted with TTA in the period of 01.01.2013 – 31.12.2014 were included in the study. We defined overtriage as the fraction of patients with TTA when ISS ≤15 and undertriage as the fraction of patients without TTA when ISS > 15. We also evaluated triage with the occurrence of emergency procedures immediately after admission. Results: 324 patients were included, 164 patients had ISS>15, 287 were admitted with TTA. Over- and undertriage were 74 % and 28 % respectively. When we used emergency procedure as reference, the figures were 83 % and 15 % respectively. Undertriaged patients had significantly more neurosurgical injuries and were significantly more often transferred from an acute care hospital. Discussion: Over- and undertriage are almost the same as before the criteria were revised, and higher thanrecommended levels. Conclusions: Revision of the TTA criteria has not improved triage, and further measures are necessary to achieveacceptable levels

Fatal injury caused by low-energy trauma – a 10-year rural cohort

Background: Death after injury with low energy has gained increasing focus lately, and seems to constitute a significant amount of trauma-related death. The aim of this study was to describe the epidemiology of deaths from low-energy trauma in a rural Norwegian cohort. Methods: All deaths from external causes in Finnmark County, Norway, from 1995 to 2004 were identified retrospectively through the Norwegian Cause of Death Registry. Deaths caused by hanging, drowning, suffocation, poisoning, and electrocution were excluded. Trauma was categorised as high energy or low energy based on mechanism of injury. All low-energy trauma deaths were then reviewed. Results: There were 262 cases of trauma death during the period. Low-energy trauma counted for 43% of the trauma deaths, with an annual crude death rate of 13 per 100,000 inhabitants. Low falls accounted for 99% of the injuries. Fractures were sustained in 89% of cases and head injuries in 11%. Ninety per cent of patients had pre-existing medical conditions, and the median age was 82 years. Death was caused by a medical condition in 85% of cases. Fifty-two per cent of the patients died after discharge from the hospital. Conclusion: In this cohort, low-energy trauma was a significant contributor to trauma related death, especially amon

Are severely injured trauma victims in Norway offered advanced pre-hospital care? National, retrospective, observational cohort

Background: Studies of severely injured patients suggest that advanced pre‐hospital care and/or rapid transportation provides a survival benefit. This benefit depends on the disposition of resources to patients with the greatest need. Norway has 19 Emergency Helicopters (HEMS) staffed by anaesthesiologists on duty 24/7/365. National regulations describe indications for their use, and the use of the national emergency medical dispatch guideline is recommended. We assessed whether severely injured patients had been treated or transported by advanced resources on a national scale. Methods: A national survey was conducted collecting data for 2013 from local trauma registries at all hospitals caring for severely injured patients. Patients were analysed according to hospital level; trauma centres or acute care hospitals with trauma functions. Patients with an Injury Severity Score (ISS) > 15 were considered severely injured. Results: Three trauma centres (75%) and 17 acute care hospitals (53%) had data for trauma patients from 2013, a total of 3535 trauma registry entries (primary admissions only), including 604 victims with an ISS > 15. Of these 604 victims, advanced resources were treating and/or transporting 51%. Sixty percent of the severely injured admitted directly to trauma centres received advanced services, while only 37% of the severely injured admitted primarily to acute care hospitals received these services. Conclusion: A highly developed and widely distributed HEMS system reached only half of severely injured trauma victims in Norway in 2013
