RESUMEN

Background: Children are at increased risk of renal injuries from blunt trauma due to their anatomic constitution. The kidney is injured in 5-20% of pediatric patients with blunt abdominal trauma. During the last decades, the management of pediatric renal injuries has evolved toward non-operative management (NOM) unless the patient is hemodynamically compromised. The aim of the present study was to assess contemporary treatment strategies and evaluate outcomes in pediatric patients with renal injuries admitted to a major Scandinavian trauma center. Methods: A retrospective cohort study of all trauma patients under 18 years admitted to our institution from January 1, 2003 to December 31, 2019 with main focus on patients with renal injury. Outcomes for two time periods were compared, 2003-2009 (Period 1; P1) and 2010-2019 (Period 2; P2), and the study cohort was also stratified into age groups, survivors and non-survivors and severity of renal injury. Results: In total, there were 4230 pediatric patients included in Oslo University Hospital Trauma Registry during this 17-year period and of these 115 (2.7%) had a renal injury. Nephrectomy was performed in four (3.5%) of the patients, angiographic embolization five (4.3%) and ureteral stent placement was performed in six patients (5.2%) due to urinary extravasation. Seven patients died, implying a crude mortality of 6.1%, with one exception secondary to traffic-related incidents. None of the deaths were attributed to renal injury and mortality fell to 1.2% in P2. Discussion: This study on contemporary pediatric renal trauma care is one of the largest from a single institution outside the USA. Our results clearly show that NOM, including minimally invasive procedures in selected cases, is achievable in more than 90% of cases with low mortality and morbidity. Level of evidence: Level IV.

RESUMEN

BACKGROUND: In line with international trends, initial treatment of trauma patients has changed substantially over the last two decades. Although trauma is the leading cause of death and disability in children globally, in-hospital pediatric trauma related mortality is expected to be low in a mature trauma system. To evaluate the performance of a major Scandinavian trauma center we assessed treatment strategies and outcomes in all pediatric trauma patients over a 16-year period. METHODS: A retrospective cohort study of all trauma patients under the age of 18 years admitted to a single institution from 1st of January 2003 to 31st of December 2018. Outcomes for two time periods were compared, 2003-2009 (Period 1; P1) and 2010-2018 (Period 2; P2). Deaths were further analyzed for preventability by the institutional trauma Mortality and Morbidity panel. RESULTS: The study cohort consisted of 3939 patients. A total of 57 patients died resulting in a crude mortality of 1.4%, nearly one quarter of the study cohort (22.6%) was severely injured (Injury Severity Score > 15) and mortality in this group decreased from 9.7% in P1 to 4.1% in P2 (p<0.001). The main cause of death was brain injury in both periods, and 55 of 57 deaths were deemed non-preventable. The rate of emergency surgical procedures performed in the emergency department (ED) decreased during the study period. None of the 11 ED thoracotomies in non-survivors were performed after 2013. CONCLUSION: A dedicated multidisciplinary trauma service with ongoing quality improvement efforts secured a low in-hospital mortality among severely injured children and a decrease in futile care. Deaths were shown to be almost exclusively non-preventable, pointing to the necessity of prioritizing prevention strategies to further decrease pediatric trauma related mortality.

RESUMEN

BACKGROUND: The elderly trauma patient has increased mortality compared with younger patients. During the last 15 years, initial treatment of severely injured patients at Oslo University Hospital Ulleval (OUHU) has changed resulting in overall improved outcomes. Whether this holds true for the elderly trauma population needs exploration and was the aim of the present study. METHODS: We performed a retrospective study of 2628 trauma patients 61 years or older admitted to OUHU during the 12-year period, 2002-2013. The population was stratified based on age (61-70 years, 71-80 years, 81 years and older) and divided into time periods: 2002-2009 (P1) and 2010-2013 (P2). Multiple logistic regression models were constructed to identify clinically relevant core variables correlated with mortality and trauma team activation rate. RESULTS: Crude mortality decreased from 19% in P1 to 13% in P2 (p<0.01) with an OR of 0.77 (95 %CI 0.65 to 0.91) when admitted in P2. Trauma team activation rates increased from 53% in P1 to 72% in P2 (p<0.01) with an OR of 2.16 (95% CI 1.93 to 2.41) for being met by a trauma team in P2. Mortality increased from 10% in the age group 61-70 years to 26% in the group above 80 years. Trauma team activation rates decreased from 71% in the age group 61-70 years to 50% in the age group older than 80 years. Median ISS were 17 in all three age groups and in both time periods. DISCUSSION: Development of a multidisciplinary dedicated trauma service is associated with increased trauma team activation rate as well as survival in geriatric trauma patients. As expected, mortality increased with age, although inversely related to the likelihood of being met by a trauma team. Trauma team activation should be considered for all trauma patients older than 70 years. LEVEL OF EVIDENCE: Level IV.

RESUMEN

BACKGROUND: The treatment of trauma victims is a complex multi-professional task in a stressful environment. We previously found that trauma team members perceive leadership as the most important human factor. The aim of the present study was to assess the experience and education of Norwegian trauma team leaders, and allow them to describe their perceived educational needs. METHODS: We conducted an anonymous descriptive study using a point prevalence methodology based on written questionnaires. All 45 hospitals in Norway receiving severely injured trauma victims were contacted on a randomly selected weeknight during November 2009. Team leaders were asked to specify what trauma related training programs they had participated in, how much experience they had, and what further training they wished, if any. RESULTS: Response rate was 82%. Slightly more than half of the team leaders were residents. The median working experience as a surgeon among team leaders was 7.5 years. Sixty-eight percent had participated in multi-professional training in non-technical skills, while 54% had passed the advanced trauma life support(ATLS) course. Fifty-one percent were trained in damage control surgery. A median of one course per team leader was needed to comply with the new proposed national standards. Team leaders considered training in damage control surgery the most needed educational objective. CONCLUSIONS: Level of experience among team leaders was highly variable and their educational background insufficient according to international and proposed national standards. Proposed national standards should be urgently implemented to ensure equal access to high quality trauma care.
