Epidemiology of severe trauma in Navarra for 10 years: out-of-hospital/ in-hospital deaths and survivors.

BACKGROUND: Major trauma is a leading cause of death. Due to the difficulties to keep a registry of these cases, few studies include all subjects, because they exclude out-of-hospital deaths. The purpose of this work was to compare the epidemiological profiles of out-of-hospital deaths, in-hospital deaths, and survivors over a 10-year period (2010-2019) of patients who had been treated by Navarre´s Health Service (Spain). METHODS: Retrospective longitudinal cohort study using data of patients injured by an external physical force of any intentionality and with a New Injury Severity Score above 15. Hangings, drownings, burns, and chokings were excluded. Intergroup differences of demographic and clinical variables were analysed using the Kruskal Wallis test, chi-squared test, or Fisher´s exact test. RESULTS: Data from 2,610 patients were analysed; 624 died out-of-hospital, 439 in-hospital, and 1,547 survived. Trauma incidences remained moderately stable over the 10-year period analysed, with a slight decrease in out-of-hospital deaths and a slight increase in in-hospital deaths. Patients of the out-of-hospital deaths group were younger (50.9 years) in comparison to in-hospital deaths and survivors. Death victims were predominantly male in all study groups. Intergroup differences regarding prior comorbidities and predominant type of injury were observed. CONCLUSIONS: There are significant differences among the three study groups. More than half of the deaths occur out-of-hospital and the causative mechanisms differ in each of them. Thus, when designing strategies, preventive measures were considered for each group on a case-by-case basis.

Severe head injury in elderly: 6-year comparison of treatment and outcome between southern Finland and Navarra (Spain).

PURPOSE: To compare the profile, treatment and outcome of elderly patients with severe traumatic brain injuries (TBI) between southern Finland and Navarra (Spain). METHODS: Data collected from, 2010 to 2015, in the Major Trauma Registry of Navarra (MTR-N) and the Helsinki Trauma Registry (HTR) were compared. Patients with New Injury Severity Score (NISS) ≥ 16 and age ≥ 65 with isolated severe TBI were considered. Patients who had been admitted to the hospital ≥ 24 h after the trauma, had been pronounced dead before hospital arrival, or had been injured by hanging, drowning or burns, were excluded. Outcome was defined by 30-day hospital mortality. The expected mortality was calculated using the Revised Injury Severity Classification score II (RISC II). Other compared data included demographics, injury mechanism, pre-hospital and hospital treatment, and time intervals. RESULTS: A total of 305 (MTR-N) and 137 (HTR) patients were included in the outcome analysis. The standardized mortality ratio with 95% confidence interval was for MTR-N 1.4 (1.1-1.6) and for HTR 0.8 (0.6-1.1). Patients in Navarra were older (average 79.7 vs. 75.0) while in southern Finland the percentage of pre-hospital intubation in patients with GCS ≤ 8 (75.0% vs 50.0%) and ICU admission (72.2% vs 22.0%) were higher. CONCLUSION: The better adjusted outcome of elderly patients with severe TBI in southern Finland in comparison to Navarra could be due to higher rate of pre-hospital intubation and/or higher rate of ICU admissions in southern Finland. Increasing number of elderly patients with severe TBI necessitate uniformly accepted protocols in pre- and in-hospital management.

¿Presenta desgate profesional el personal de urgencias extrahospitalarias? Resultados Encuestas de Malasch / Are out-of-Hospital Emergency Medical Services Suffering from Professional Burn-Out? Maslach Burnout Inventory Results

OBJETIVO: Determinar la prevalencia del Burnout en el personal de urgencias extrahospitalarias. MATERIAL Y MÉTODOS: Estudio observacional, descriptivo y transversal. Se les aplicó una ficha con unos datos profesionales y el cuestionario de Maslach de 22 items y se realizó un análisis estadístico descriptivo basado en obtener las frecuencias tanto absolutas como relativas. Además de la media y la desviación típica, se ha realizado un contraste de la hipótesis de Kruskal-Wallis y la de Wilcoxon. Para analizar la fiabilidad y validez de la escala se ha obtenido los coeficientes alfa de Cronbach para las 3 subescalas. RESULTADOS: Respecto al tiempo trabajado dentro de la categoría profesional los conductores que llevan menos de un año presentan mayor burnout. En relación al tipo de contrato, son los de contrato fijo. A peor estado de salud (regular o malo) mayor es el burnout. Las personas solteras presentan mayor cansancio emocional y no trabajar con los mismos compañeros aumenta también la presencia de este fenómeno. El burnout no se presenta en los trabajadores con turno de 24 horas, sin embargo, se ve en los otros turnos. No hay diferencias estadísticas en la puntuación por el escaso tamaño de la muestra con jornada reducida. CONCLUSIONES: El interés de este estudio radica en conocer el grado de cansancio emocional que presentan los profesionales de urgencias extrahospitalarias y evidenciar la necesidad de tomar medidas preventivas. Los resultados de nuestro estudio están en la línea de los publicados

OBJECTIVE: To determine the prevalence of Burnout in out-of-hospital emergency medical personnel. MATERIAL AND METHODS: Observational, descriptive and transversal study. A professional data sheet and the Maslach Burnout Inventory of 22 items were applied. In order to get the absolute and relative frequencies a descriptive statistical analysis was performed. In addition to the mean and the standard deviation, a contrast to the Kruskal-Wallis hypothesis and the Wilcoxon hypothesis was shown. In order to analyze the reliability and validity of the scale, Cronbach's alpha coefficients were obtained for the 3 subscales. RESULTS: Regarding the time worked in the professional category, the drivers who have been driving for less than a year have higher levels of burnout. In relation to the type of contract are those of fixed-term contract. The worse the state of health (regular or bad) is, the greater the burnout. Single people have greater emotional exhaustion. The fact of not working with the same partners also increases this phenomenon. Burnout does not occur in workers with 24-hour shift, but it occurs in other shifts. Due to the small size of the short-time working sample, no statistical differences were found in the score. CONCLUSIONS: The interest of this study lies in knowing the emotional exhaustion level from the out-of-hospital emergency professionals, as well as evidencing the need to take preventive measures. The results of our study are in line with those published

Quality assessment of Major Trauma Registry of Navarra: completeness and correctness.

This study assessed the completeness of the Major Trauma Registry of Navarra (MTR-N) data and their concordance with the patients' medical files. It retrospectively reviewed all the MTR-N cases documented in June and July of 2014 and 2015. For each case, 42 parameters' values were taken from the MTR-N. To assess concordance between the MTR-N and medical files, the same variables values were re-recorded. Data completeness was calculated for all cases and data correctness for those documented in the MTR-N, separately for each variable. The overall average completeness rate for all variables was 92.8%. The percentages of completely missing data ranged from 0% (29 variables) to 76.8% (base excess). The overall average rate of correctness was 98.0%. Exact concordance ranged from 93.0% (7 variables) to 100% (22 variables). This study demonstrates the reliability and validity of the MTR-N data and its effectiveness for quality improvement and research in our community.

¿Es adecuado el lavado de la ropa laboral de los profesionales de las ambulancias de urgencia en España? / Emergency Ambulance Professionals in Spain, Is The Working Clothes Washing Appropriate?

Introducción: Según el estudio EPINE-EPPS del 9 de Noviembre de 2017 realizado en 313 hospitales españoles y estudiado a 61.673 pacientes, de ellos 1493 ya la tenían antes del ingreso. Objetivo: Valorar si el personal de urgencias extrahospitalarias limpia correctamente su uniforme ya que es muy común que laven esta ropa en sus domicilios. Material y Métodos: Consistió en estudio descriptivo de las variables cerradas, con una población de estudio de 126 profesionales. Se les encuestó a través de una aplicación de formulario Google. El tiempo que permaneció abierto el acceso a la encuesta fue de Junio a Noviembre de 2017. Los datos se analizaron con el programa informático R y ha consistido en la obtención de tablas de frecuencias absolutas y relativas. También para cada par de variables, se han realizado los contrastes de independencia exactos de Fisher y para todas aquellas tablas de contingencia 2x2, se ha calculado el Odds Ratio junto a su intervalo de confianza a nivel 95%. Resultados: Tipo de servicio en el que se trabaja y cuestión sobre si la empresa lava la ropa (p-valor = 0.00). El Odds Ratio muestra que la razón de encuestados cuya empresa lava la ropa en el tipo de servicio público es 17,53 veces la razón en el servicio privado. Conclusiones: Más de la mitad de los encuestados lava la ropa laboral en su domicilio todos los días que trabaja con el consiguiente riesgo que eso genera de que los microorganismos se queden en su lavadora. Además, desconocer también qué tipo de lavado es el adecuado disminuye su vida útil

Introduction: According to the EPINE-EPPS study of November 9, 2017 carried out in 313 Spanish hospitals and studied 61,673 patients, 1493 of them had already it before admission. Objective: To evaluate if the outpatient emergency staff clean their uniform correctly, since it is very common to wash these clothes at home. Material and Methods: Consisted in a descriptive study of closed variables, with a study population of 126 professionals. They were surveyed through a Google Form application. The time for getting access to the survey remained open from June to November 2017. The data was analyzed with the computer program R obtaining tables of absolute and relative frequencies. Also for each pair of variables, the contrasts of Fisher’s exact test of independence have been made, and for all those 2x2 contingency tables the Odds Ratio has been calculated together with its 95% confidence interval. Results: Type of service in which it is being worked and the question about whether the company washes clothing (p-value = 0.00). The Odds Ratio shows that the ratio of respondents whose company washes clothes in the public service type is 17.53 times the ratio in the private service. Conclusions: More than half of the respondents wash their working clothes at home every day they work, causing the consequent risk that the microorganisms can remain in their washing machine. In addition, not knowing what type of washing is also the most appropriate will decrease its useful life

Objective. To validate the Mortality Prediction Model of Navarre (MPMN) to predict death after severe trauma and compare it to the Revised Injury Severity Classification Score II (RISCII). Methods. Retrospective analysis of a cohort of severe trauma patients (New Injury Severity Score >15) who were attended by emergency services in the Spanish autonomous community of Navarre between 2013 and 2015. The outcome variable was 30-day all-cause mortality. Risk was calculated with the MPMN and the RISCII. The performance of each model was assessed with the area under the receiver operating characteristic (ROC) curve and precision with respect to observed mortality. Calibration was assessed with the Hosmer-Lemeshow test. Results. We included 516 patients. The mean (SD) age was 56 (23) years, and 363 (70%) were males. Ninety patients (17.4%) died within 30 days. The 30-day mortality rates predicted by the MPMN and RISCII were 16.4% and 15.4%, respectively. The areas under the ROC curves were 0.925 (95% CI, 0.902-0.952) for the MPMN and 0.941 (95% CI, 0.921-0.962) for the RISCII (P=0.269, DeLong test). Calibration statistics were 13.6 (P=.09) for the MPMN and 8.9 (P=.35) for the RISCII. Conclusions. Both the MPMN and the RISCII show good ability to discriminate risk and predict 30-day all-cause mortality in severe trauma patients (AU)

Epidemiological Characteristics and Overall Burden of Accidental Injuries in Navarra, Spain: Epidemiology of Injuries in Children.

Injuries caused by accidents or violent situations in pediatric patients are a serious social problem where prevention plays a key role. The aim of this study was to describe the epidemiological situation of pediatric injuries in Spain. A prospective study of pediatric patients receiving care in the Emergency Service of the Complejo Hospitalario de Navarra due to for reasons of accidental injury was conducted. The study covered a period of 1 year and assessed a total of 16 variables. There were a total of 8,876 patients, of whom 56.4% were males. Traumatic injuries such as fractures and craniocerebral trauma were identified as the most frequent injuries, occurring as a result of injuries mainly in the home. In females, there was a decrease in the incidence of injuries related to age. There was a greater incidence at the end of the day, during the weekend, and in the months of March to October. The epidemiological profile of pediatric patients who met with accidents in Navarra, Spain, is described. The knowledge of the main areas and factors related to injuries allows us to improve preventive measures, which would contribute to better control in this region of Spain.

La importancia de incluir las muertes prehospitalarias en los registros de traumatismo grave y su relación con la letalidad y la capacidad de predicción de la supervivencia / Inclusion of prehospital mortality statistics in severe trauma registries: a study of the influence of inclusion on trauma lethality rates and survival prediction

Objetivo: Comparar la frecuencia y características de las muertes por traumatismo grave prehospitalarias y hospitalarias, así como conocer la capacidad de la gravedad de la lesión asociada a la edad para predecir la muerte y su variación según se incluyan o no las muertes prehospitalarias. Método: Estudio descriptivo, analítico de cohorte retrospectiva realizado en Navarra sobre 918 pacientes politraumatizados atendidos por los servicios médicos de emergencia durante 2010-2013. Se estudió la letalidad por causas y se modeló la predicción de la mortalidad a través de regresión logística para comparar la precisión de los modelos. Resultados: La mayoría de las muertes fueron prehospitalarias. Tres cuartas partes de las muertes ocurrieron en el ámbito prehospitalario en menores de 65 años. Al incorporar las muertes prehospitalarias las tasas de letalidad de los mecanismos relacionados con el tráfico pasaron del 16 al 42% y las producidas por armas del 13 al 70%. Al realizar la predicción del fallecimiento a través de la regresión logística tomando como variable independiente el NISS (New Injury Severity Score) y como variable de control la edad, existen mínimas variaciones si se compara el grupo de pacientes que llegan vivos al hospital con el de la suma de estos pacientes con los fallecidos in situ. Conclusión: Las muertes prehospitalarias constituyen la mayoría de las muertes por traumatismo y difieren en las características principales con los fallecimientos que se producen en el hospital. La incorporación de las muertes prehospitalarias no modifica la capacidad predictiva de mortalidad de un modelo de regresión logística que incluya la edad y el NISS (AU)

Objectives: To compare the frequency and characteristics of prehospital and hospital deaths and assess whether injury severity and age can predict mortality when prehospital deaths are included or excluded from total mortality. Methods: Descriptive analysis of a retrospective cohort of 918 patients with multiple injuries attended by emergency medical services in Navarre, Spain, in 2010-2013. We analyzed prehospital and hospital deaths by cause of injuries and developed and compared the precision of logistic regression models to predict mortality. Results: Most deaths occurred before arrival at a hospital. Three quarters of prehospital deaths occurred in patients under the age of 65 years. When prehospital deaths were included in the analysis, the lethality rate after traffic accidents rose from 16% to 42%; lethality from firearm injuries rose from 13% to 70%. When the model using the new injury severity score and age as independent variables was asked to predict survival with and without data for deaths at the scene or during transfer to a hospital, the model’s performance differed only slightly. Conclusions: Most deaths from injuries occur before patients reach a hospital. The main characteristics of prehospital and hospital deaths differ. Including data for prehospital deaths in regression models does not change survival prediction based on injury severity and age (AU)

Cambios durante la última década en la incidencia y las características de los pacientes politraumatizados en Navarra / Changes in the characteristics and incidence of multiple-injury accidents in the Navarre community over a 10-year period

Objetivo: Comparar las tasas de morbimortalidad, el perfil epidemiológico y la supervivencia de los pacientes politraumatizados atendidos en Navarra por el sistema de emergencias en los períodos 2002-2003 y 2010-2012. Método: Estudio observacional, analítico, de dos cohortes de pacientes accidentados con un Injury Severity Score superior a 15 puntos. Se utiliza la regresión logística para identificar las variables involucradas en la mortalidad. Resultados: Se incluyen 651 pacientes atendidos en el primer periodo y se comparan con los 626 del segundo. La tasa de incidencia descendió de 58,1 a 33,5/100.000 habitantes y año, así como la de mortalidad, que descendió de 30,3 a 15,3. La edad media de los accidentados pasó de 45 (22) a 52 (23) años y se mantuvo su distribución por sexos (75% varones). Disminuyeron los accidentados de tráfico del 44 al 24% y se incrementaron las caídas en ancianos del 9 al 26%. Conclusiones: En los últimos años se ha controlado en Navarra el problema de los jóvenes accidentados de tráfico y ha surgido el grupo de ancianos que se caen accidentalmente. Esto puede ralentizar la mejora en las tasas de mortalidad de los politraumatizados y obliga a poner en marcha medidas preventivas en relación con este mecanismo en este colectivo (AU)

Objective: To compare morbidity and mortality rates, the epidemiologic profile, and survival of patients with multiple injuries attended by the emergency services in the Navarre autonomous community in Spain in the periods of 2002–2003 and 2010–2012. Methods: Observational analysis of 2 cohorts of accident patients with Injury Severity Scores of 15 points or more. Logistic regression was used to identify variables related to mortality. Results: A total of 651 patients were attended in the first period; 626 were attended in the second. The annual multiple-injury incidence rate decreased from 58.1 per 100 000 population in the first period to 33.5 per 100 000 population in the second; mortality decreased from 30.3 to 15.3 per 100 000 population. The mean (SD) age was 45 (22) years in the first cohort and 52 (23) years in the second. The gender distribution (75% male) did not change. The percentage injured in traffic accidents decreased from 44% to 24%; the percentage of elderly patients hurt in falls increased from 9% to 26%. Conclusions: The problem of the number of young people injured in accidents in our community has been brought under control, but the proportion of older patients injured in falls has risen. This change may slow the effort to improve mortality rates in patients with multiple injuries and it obliges us to introduce measures to prevent falls in the elderly (AU)

Differences in the treatment and evolution of acute coronary syndromes according to gender: what are the causes?

AIMS AND OBJECTIVES: The objectives of this study were to analyse the differences in the treatment and the evolution of acute coronary syndromes according to the gender of the patient and to determine the likely causes of these differences. BACKGROUND: Epidemiological studies confirm the differences in the course and treatment of acute coronary syndromes according to factors such as gender and age. The factors associated with the observed gender-based differences are not known. DESIGN AND METHODS: This prospective study was conducted on 596 patients treated in the Hospital Emergency Service of the Hospital Complex of Navarra, Spain, from 1 January 2012 to April 2013 with acute coronary syndromes. A bivariate and logistic analysis has been made by adjusting the age and severity of process to know the differences by gender. RESULTS: A total of 71·8% (n = 428) were men, and the remaining 28·2% (168) were women. The mean age of the men was 66·4 ± 12·7 years, and the mean age of the women was 72·5 ± 13·9 years. We found that antiplatelet drugs (68·4 vs. 22·7%), blockers (70 vs. 25·4%), ACE inhibitors (56·2 vs. 15·6%), fibrinolysis (17·2 vs. 4·5%, p = 0·025) and primary angioplasty (AP) (38·7 vs. 16·3%, p = 0·008) were less frequently administered to women compared with men. We observed an additional delay in the demand for health care in women with acute coronary syndromes compared with men. CONCLUSIONS: There is an association between treatment differences and gender. The delay in the request of health care in women is observed to be the largest correlating factor, in addition to voluntary discharge in women affected by acute coronary syndromes. RELEVANCE TO CLINICAL PRACTICE: Delays in seeking medical care or voluntary discharge are likely factors related to worse outcomes in women. These factors should be explored, and the results should be made available to the public, particularly to women.

Esto puede ralentizar la mejora en las tasas de mortalidad de los politraumatizados y obliga a poner en marcha medidas preventivas en relación con este mecanismo en este colectivo.

Percepción y actuación de los pacientes con patología coronaria aguda en la fase prehospitalaria / Perception and action by patients with Acute Coronary Failure in the prehospital phase

El estudio de desigualdad de género en el ámbito sanitario muestra la existencia de diferencias en la actuación profesional según sexo en las patologías coronarias. OBJETIVOS: este trabajo pretende conocer la percepción y actuación de los pacientes con patología coronaria aguda e identificar los factores relacionados con la demora en la solicitud de asistencia sanitaria. MÉTODO: estudio descriptivo, analítico y transversal con pacientes diagnosticados de patología coronaria aguda (IAM o angina inestable)hospitalizados en las unidades de cardiología y/o en la unidad coronaria del Complejo Hospitalario de Navarra (CHN), entre el 1 de enero y el 1 de julio de 2012. Muestreo no probalístico, excluidos los pacientes con más de 48 horas de ingreso y aquellos cuyo episodio coronario era de repetición. Recogida de información mediante un cuestionario de 13ítems sobre la percepción del estado general de salud previo, cambios del estado emocional, existencia de cargas familiares, tiempo transcurrido desde la apariación de síntomas y la solicitud de ayuda, causas del retraso y autopercepción del conocimiento de la patologia coronaria. RESULTADOS: se realizaron 113 encuestas, de las cuales un 71,7% fueron hombres, cuya edad media fue de 67 años y de 72 años en las mujeres(p= 0,041). La media de minutos transcurridos hasta solicitar asistencia fue de 138 en los hombres y 238 en las mujeres (p= 0,001).También se hallaron diferencias significativas en la percepción del estado de salud, la gravedad del proceso, la carga familiar, el grado de actividad en el momento del episodio, el reconocimiento de la gravedad y la autopercepción del conocimiento. CONCLUSIONES: hallamos un mayor retraso en la demanda de atención sanitaria en las mujeres, así como diferencias psicosociales relacionadas con esta actuación

The study on gender inequality within the healthcare setting shows the current differences in professional activity on cardiac conditions according to gender. OBJECTIVES: this article intends to understand the perception and action of patients with Acute Coronary Failure, and to identify those factors associated with the delay in requesting medical care. METHOD: descriptive, analytical and transversal study with patients diagnosed with Acute Coronary Failure (AMI or unstable angina), admitted to the Cardiology Unit and/or the Coronary Unit of the Complejo Hospitalario de Navarra (CHN), between January, 1st and July, 1st,2012. Non-probabilistic sample, excluding patients with over 48 hours since admission, and those with a repeated coronary episode. Information was collected through a 13-item questionnaire about the perception of their previous health status, changes in emotional state, presence of family obligations, period of time since symptom initiation and until help was requested, causes for this delay, and self-perception of knowledge about the coronary condition. RESULTS: 113 questionnaires were completed, out of which 71.7% were completed by male patients. The mean age was 67 years in men and 72years in women (p = 0.041). The average minutes elapsed until help was requested was 138 in men and 238 in women (p= 0.001). There were also significant differences in the perception of health status, severity of the condition, family obligations, level of activity at the time of the episode, acknowledgement of severity, and self-perception of knowledge. CONCLUSIONS: we found a higher delay in the demand for medical care in women, as well as psychosocial differences associated with this action

[Seroprevalence of Lyme disease in Navarra, Spain]. / Seroprevalencia de la enfermedad de Lyme en Navarra.

BACKGROUND AND OBJECTIVE: To establish the seroprevalence of infection by Borrelia burgdorferi in Navarre (Spain). PATIENTS AND METHOD: Serum samples of 1,429 individuals considered representative of the population of Navarre were analyzed. The individuals were recruited from a list issued by the government of Navarre. The subjects were stratified according to three variables: age, sex and the health zone to which they belonged. In all cases a written informed consent was obtained. RESULTS: The global seroprevalence in Navarre was 4.4%. Being a stockbreeder (13.2%) in contact with cows and sheep was found to be a risk factor after the analysis of different variables such as sex, age, contact with cattle, profession, living in rural areas, a prior history of having been bitten by a tick or the size of the city. CONCLUSIONS: Navarre provides suitable conditions for the prevalence and development of Lyme disease, with a global seroprevalence or 4.4%. No differences were found between the different areas analyzed, while being a stockbreeder represents a risk factor.
