Emergency crisis resource management: a simulation-based course developed by the Spanish Society of Emergency Medicine (SEMES) for health sciences students. / Emergency Crisis Resource Management de la Sociedad Española de Medicina de Urgencias y Emergencias: curso de gestión en crisis basado en simulación para estudiantes de ciencias de la salud.

OBJECTIVES: Educational programs based on high-fidelity simulation training aim to promote students' acquisition of nontechnical competencies such as understanding crisis resource management (CRM). This study evaluated the efficacy of a CRM course for students in their last year of university studies in health sciences. The course was developed by the Spanish Society of Emergency Medicine (SEMES). MATERIAL AND METHODS: Quasi-experimental study of a high-fidelity simulation course to teach emergency CRM (E-CRM) using preand postcourse measures of achievement in a single student cohort. A total of 209 students completed 2 selfadministered self-efficacy evaluations of their acquisition of nontechnical competencies and resilience. External observers also assessed the students' nontechnical competencies with objective measurement scales. RESULTS: Scores on resilience and self-efficacy assessments improved through the intervention (F = 25.90 and F = 68.02, respectively; P .001, for both pre-post comparisons). Statistically significant differences were found between students in different health sciences at baseline (t = 2.67; P = .008). Scores improved significantly on the Mayo High Performance Teamwork Scale (F = 6.18, P .001, eta2 = 0.20) and the Ottawa CRM Global Rating Scale (F = 5.58; P .005, eta2 = 0.19). CONCLUSION: The E-CRM course developed by a coordinated multiprofessional team based on high-fidelity simulations improved self-efficacy assessments of resilience and all nontechnical competencies.

OBJETIVO: Los programas educativos dirigidos a la adquisición de competencias no técnicas, tales como el Crisis Resource Management (CRM), basado en simulación de alta fidelidad, implican un aumento de las competencias del alumno en el manejo de situaciones de crisis. El objetivo del presente trabajo es evaluar la eficacia del programa Emergency CRM (E-CRM) de la Sociedad Española de Medicina de Urgencias y Emergencias, dirigido a estudiantes de último año de los grados de ciencias de la salud. METODO: Se llevó a cabo un estudio cuasiexperimental con medidas pre y posintervención, que consistió en un programa de E-CRM con simulación de alta fidelidad, en un único grupo. Participaron un total de 209 estudiantes que completaron dos instrumentos autoadministrados sobre la autoeficacia hacia las competencias no técnicas y la resiliencia. Además, a través de observadores externos se evaluó sus competencias no técnicas con instrumentos de evaluación objetivos. RESULTADOS: El alumnado mejoró las puntuaciones de resiliencia (F = 25,90; p < 0,001) y autoeficacia (F = 68,02; p 0,001) tras la intervención, con diferencias estadísticamente significativas para la resiliencia en la línea basal en función del grupo de estudios (t = 2,67; p = 0,008). Por otro lado, se encontraron mejoras de las puntuaciones obtenidas tanto para el instrumento Mayo High Performance Teamwork Scale (F = 6,18; p 0,001; eta2 = 0,20) como para el Ottawa Global Rating Scale Crisis Resource Management (F = 5,58; p 0,005; eta2 = 0,19). CONCLUSIONES: El programa de E-CRM, basado en simulación de alta fidelidad, con un equipo interprofesional coordinado, mejora la autoeficacia en todas las competencias no técnicas medidas y aumenta la resiliencia.

Donation after cardiac death: results of the SUMMA 112 - Hospital 12 de Octubre Program.

BACKGROUND: In 2005, our center started a donation after cardiac death (DACD) program, by which patients who present an irreversible cardiac arrest outside hospital are brought to our center with the purpose of organ donation. We reviewed the outcomes of our program of kidney transplants from DACD. METHODS: We conducted a retrospective study of the DACD, and we reviewed the procedures carried out in our institution between July 2005 and December 2010 and descriptively analyzed the results obtained for kidney donation. RESULTS: One hundred and fifty-two of 274 potential donors were transferred to our hospital. Of them, 126 (82.8%) were connected to cardiopulmonary bypass machine, and organs were procured in 113 donors (74.3%). The discarded grafts were mainly due to inadequate perfusion. One hundred and fifty-six kidneys were transplanted (51.3%). Over a median follow-up period of 18 ± 13.7 months, the median creatinine clearance was 78.2 ± 10.2 ml/min. 8.6% of the grafts had no primary function, and 85% had a delayed graft function. Recipient survival and graft survival were 98% and 87%, respectively. CONCLUSIONS: DACD is an adequate source of organs for kidney transplantation. Our functional and survival results are encouraged in the short term, although further work is required to increase the program's benefits.

Lung transplant of extrahospitalary donor after cardiac death.

Non-heart-beating donors (NHBDs) have to meet the predefined criteria for organ donation including death from irreversible cessation of the beating heart. The Maastricht conference defined 4 NHBD categories to differentiate their viability and ethical-legal support. In Spain, NHBDs who originate from an out-of-hospital setting correspond to type II donors. These are patients who have had a cardiac arrest outside hospital and, after failed CPR attempts, are transferred with hemodynamic support measures to the hospital for organ donation. The Hospital Clínico San Carlos also has a lung donation program in collaboration with the Hospital Puerta de Hierro in Madrid and the Hospital Marques de Valdecilla in Santander. The objective of this study is to describe the results of lung transplantation of after cardiac death program, specifically the section regarding lung extraction donation. Twenty potential lung donors were obtained during the study. Most patients were male (19 cases), with a mean age of 42 years (36.5-49.5 years). A total of 33 lungs were donated (18 right and 15 left lungs). Most extractions were multiorganic (19 cases). One liver, 19 kidneys, 2 pancreas, and 19 corneas were obtained from these donors; bone tissue was obtained from all donors. The transplantation was bipulmonary in 13 cases and unipulmonary in 7. Thirty days after transplantation, 2 recipients died, 1 died of stroke associated with bilateral pneumonia and 1 died of hypovolemic shock resulting from hemothorax. The remaining 18 patients were progressing well at 30 days. Our data suggest that lung transplantation from patients after extrahospitalary cardiac death is feasible.

Influence of donor capnometry on renal graft evolution in uncontrolled donation after circulatory death.

AIM: To analyse the association between donor capnometry data and the short-term evolution of kidney grafts in cases of uncontrolled donation after circulatory death (uDCD). METHOD: We used an ambispective observational study design, conducted in the Community of Madrid between January and December 2019, inclusive. Patients who suffered out-of-hospital cardiac arrest (CA) with no response to advanced cardiopulmonary resuscitation (CPR) were selected as potential donors. Donor capnometry levels were measured at the start, midpoint and transfer to hospital then compared with indicators of renal graft evolution. RESULTS: The initial selection included 34 possible donors, of which 12 (35.2%) were viable donors from whom 22 (32.3%) kidneys were recovered. There was a correlation between the highest capnometry values and less need for post-transplant dialysis (≥24 mmHg, p < 0.017), fewer dialysis sessions and fewer days to recover correct renal function (Rho -0.47, p < 0.044). There was a significant inverse correlation between the capnometry values at transfer and 1-month post-transplant creatinine levels (Rho -0.62, p < 0.033). There were no significant differences between the capnometry values at transfer and primary nonfunction (PNF) or warm ischaemia time. One-year patient survival was 100% for patient receiving organ donation, while graft survival was 95%. CONCLUSIONS: Capnometry levels at transfer are a useful predictor of the short-term function and viability of kidney transplants from uncontrolled donations after circulatory death.

Alternative CPAP methods for the treatment of secondary serious respiratory failure due to pneumonia by COVID-19.

INTRODUCTION: The use of devices that provide continuous positive pressure in the airway has shown improvement in various pathologies that cause respiratory failure. In the COVID 19 pandemic episode the use of these devices has become widespread, but, due to the shortage of conventional CPAP devices, alternative devices have been manufactured. The objective of this study is to describe the use of these devices, as well as their efficacy. MATERIAL AND METHODS: Data are collected from patients admitted for Pneumonia due to COVID 19 at the IFEMA Field Hospital. Data are collected from 23 patients with respiratory failure and need for ventilatory support. RESULTS: Study carried out on a total of 23 patients, dated admission to IFEMA. Alternative CPAP was used in five patients (21.7%), while ventilatory support with a reservoir mask or Ventimask Venturi effect was used in the remaining 18 patients (78.3%). A progressive increase in saturation is observed in those patients in whom alternative CPAP was used (from 94% on average to 98% and 99% on average after 30 and 60 min with the mask, respectively), although this change was not significant (p = 0.058 and p = 0.122 respectively). No significant change in RF was observed at the beginning and end of the measurement in patients who used alternative CPAP (p = 0.423), but among those who did not use alternative CPAP (p = 0.001). A statistically significant improvement in the variable oxygen saturation / fraction inspired by oxygen is observed in patients who used alternative CPAP (p = 0.040). CONCLUSION: The use of these devices has helped the ventilatory work of several patients by improving their oxygenation parameters. To better observe the evolution of patients undergoing this therapy and compare them with patients with other types of ventilatory support, further studies are necessary.

INTRODUCCIÓN: El uso de dispositivos que aportan presión positiva continua en la vía aérea ha demostrado mejoría en diversas patologías que producen insuficiencia respiratoria. En el episodio de pandemia por COVID 19 el uso de estos dispositivos se ha generalizado, pero, debido a la escasez de dispositivos convencionales de CPAP, se han fabricado dispositivos alternativos. El objetivo de este estudio es describir el uso de estos dispositivos, así como su eficacia. MATERIAL Y MÉTODOS: Se recogen datos de pacientes ingresados por Neumonía por COVID 19 en el Hospital de campaña de IFEMA. Se recogen datos de pacientes con insuficiencia respiratoria y necesidad de soporte ventilatorio. RESULTADOS: Estudio realizado sobre un total de 23 pacientes, con fecha ingreso en IFEMA. Se empleó CPAP alternativa en cinco pacientes (21,7%), mientras que en los 18 pacientes restantes (78,3%) se usó soporte ventilatorio con mascarilla reservorio o Ventimask efecto Venturi. Se observa un aumento progresivo de la saturación en aquellos pacientes en los que se empleó CPAP alternativa (de 94% de promedio a 98% y 99% de promedio tras 30 y 60 minutos con la máscara, respectivamente), aunque este cambio no resultó significativo (p = 0,058 y p = 0,122 respectivamente). No se observó un cambio significativo de frecuencia respiratoria al inicio y final de la medición en pacientes que usaron CPAP alternativa (p = 0,423) pero si entre los que no la usaron (p = 0,001). Se observa una mejoría estadísticamente significativa en la variable Saturación de oxigeno / Fracción inspirado de oxígeno en los pacientes que usaron CPAP alternativa (p = 0,040). CONCLUSIÓN: El uso de estos dispositivos ha ayudado al trabajo ventilatorio de varios pacientes mejorando sus parámetros de oxigenación. Para observar mejor la evolución de los pacientes sometidos a esta terapia y compararlos con pacientes con otro tipo de soporte ventilatorio, son necesarios más estudios en los que se aleatorice su uso.

Family Refusal to Consent Donation: Retrospective Quantitative Analysis of Its Increasing Tendency and the Associated Factors Over the Last Decade at a Spanish Hospital.

BACKGROUND: Organ and tissue recovery remains limited by several factors. This study retrospectively analyzes the factors associated with family refusal to consent to donation at a high-donor-volume Spanish hospital. METHODS: Data regarding the annual number of potential donors and family refusal rates at hospital and regional levels were retrieved from 2008 to 2017. Descriptive, bivariate, and multivariate analyses were performed to detect those factors independently associated with family refusal. Results were cross-validated using the data from years 2018 and 2019 as the validation group. To explore potential inter-relations between factors a Multiple Correspondence Analysis was performed. RESULTS: A total of 601 family interviews for petition of consent were conducted between 2008 and 2017, 531 (88.4%) resulted in acceptance and 70 (11.6%) resulted in refusal of the donation. Lesser experience of the interviewers (odds ratio [OR], 2.980; P = .001), donation after brain death (OR, 2.485; P = .013), number of interviews conducted per family (OR, 1.892; P < .001), age of the main decision maker (OR, 1.025; P = .045), and high or middle attributed cultural levels (OR, 0.142; P < .001 and OR, 0.199; P < .001 respectively) were observed to be independently associated with the family final decision. The logistic regression model displayed good predictive power for both derivation and validation cohorts, with an overall predictive accuracy of 80.9% (95% confidence interval, 0.747-0.870; P < .001) and 74.4% (95% confidence interval, 0.635-0.854; P = .001), respectively. CONCLUSIONS: Transplant coordination team members having a thorough knowledge of the family decision mechanisms may be a key factor in donation process optimization.

Beta-blocker effect on ST-segment: a prespecified analysis of the EARLY-BAMI randomised trial.

OBJECTIVE: The effect of early intravenous (IV) beta-blockers (BBs) administration in patients undergoing primary percutaneous coronary intervention (pPCI) on ST-segment deviation is unknown. We undertook a prespecified secondary analysis of the Early Beta-blocker Administration before primary PCI in patients with ST-elevation Myocardial Infarction (EARLY-BAMI) trial to investigate the effect of early IV BB on ST-segment deviation. METHODS: The EARLY-BAMI trial randomised patients with ST-elevation myocardial infarction (STEMI) to IV metoprolol (2×5 mg bolus) or matched placebo before pPCI. The prespecified outcome, evaluated by an independent core laboratory blinded to study treatment, was the residual ST-segment deviation 1 hour after pPCI (ie, the percentage of patients with >3 mm cumulative ST deviation at 1 hour after pPCI). RESULTS: An ECG for the evaluation of residual ST-segment deviation 1 hour after pPCI was available in 442 out of 683 randomised patients. The BB group had a lower heart rate after pPCI compared with placebo (71.2±13.2 vs 74.3±13.6, p=0.016); however, no differences were noted in the percentages of patients with >3 mm cumulative ST deviation at 1 hour after pPCI (58.6% vs 54.1%, p=0.38, in BB vs placebo, respectively) neither a significant difference was found for the percentages of patients in each of the four prespecified groups (normalised ST-segment; 1-3 mm; 4-6 mm;>6 mm residual ST-deviation). CONCLUSIONS: In patients with STEMI, who were being transported for primary PCI, early IV BB administration did not significantly affect ST-segment deviation after pPCI compared with placebo. The neutral result of early IV BB administration on an early marker of pharmacological effect is consistent with the absence of subsequent improvement of clinical outcomes.

Analysis of organ procurement from non-heart-beating donors over a 10-year period in Madrid. / Análisis de la donación en asistolia no controlada durante 10 años en la Comunidad de Madrid.

OBJECTIVES: The Autonomous Community of Madrid procures the largest number of organs from uncontrolled non-heart-beating donors (NHBD) after circulatory death in Spain. The aim of this study was to analyze the yield of these donations in terms of viable organs procured (category IIa) according to information extracted from the CORE registry of the Spanish National Transplant Organization (ONT) for the Madrid area. METHODS: Retrospective observational study of NHBD data registered between 2007 and 2017, including age, height, weight, body mass index (BMI), emergency care times, method of chest compressions applied (mechanical cardiopump vs manual compressions), and viable organs extracted. RESULTS: A total of 679 circulatory death donors were registered; 458 (67.6%) of them were utilized donors. The median BMI correlated negatively (-0.161) with the number of viable organs extracted (P<.001). The method of applying chest compressions significantly influenced liver viability: only those extracted after mechanical cardiopump compressions were viable for transplantation. Type of compressions did not effect kidney or lung viability. CONCLUSION: Variables to bear in mind as predictors of success in NHBD donation are BMI and type of chest compressions applied.

OBJETIVO: La Comunidad de Madrid es líder en donación en asistolia no controlada (DANC) en España. El objetivo de este trabajo es analizar la rentabilidad de los órganos extraídos válidos de los donantes (categoría IIa) del Registro Nacional Integrado de Información de Donación y Trasplante de la ONT (Registro CORE), correspondientes a esta comunidad. METODO: Estudio observacional retrospectivo entre 2007 y 2017 de las DANC, analizando las variables edad, talla, peso, índice de masa corporal (IMC), tiempos asistenciales, tipo de compresión torácica recibida durante la reanimación cardiopulmonar (cardiocompresor mecánico vs compresión torácica manual) y órganos extraídos válidos. RESULTADOS: Se registraron 679 donantes, de los que fueron donantes efectivos el 67,6% (n = 458). Se observó una correlación negativa (−0,161) entre la mediana del índice de masa corporal y la mediana del número de órganos extraídos válidos (p < 0,001). También se observó una influencia estadísticamente significativa del tipo de cardiocompresión realizada y la viabilidad del hígado, puesto que solo los extraídos tras reanimación con cardiocompresión mecánica fueron válidos para trasplante. CONCLUSIONES: El IMC y el uso de cardiocompresores mecánicos son variables predictoras a tener en cuenta ante una posible DANC.

Uncontrolled donation programs after out-of-hospital cardiac arrest. An estimation of potential donors.

OBJECTIVE: To determine the number of potential deceased organ donors from out-of- hospital cardiac arrest cases (OHCA) attended by public physician-led emergency medical services in Spain, based on data recorded in the nationwide Spanish OHCA Registry (OHSCAR). MATERIAL AND METHODS: We analysed OHSCAR data on deceased OHCA patients in Spain during 13 months (1/10/2013 to 31/10/2014). Variables included age, sex, estimated OHCA time, cardiopulmonary resuscitation (CPR) start time and outcome. Inclusion criteria were: age 16-60 years, witnessed OHCA, no return of spontaneous circulation (ROSC) and time interval <15min between OHCA occurrence and CPR initiation. RESULTS: Of a total 8789 cases, 3290 met the age criteria; of these, CPR was not witnessed in 745 cases. Among the remaining 2545 patients, 141 were included in uncontrolled donation after cardiac death (uDCD) programs, 902 arrived at the hospital with ROSC, 64 arrived with ongoing CPR and 15 cases were lost to follow-up. Of the remaining 1423 without ROSC, CPR initiation time was not recorded in 454 cases and 398 did not meet the time criteria <15min between OHCA and CPR initiation. Finally, 571 met all the criteria and could have been potential donors. There were significant differences in the actual donors percentage from potential donors percentage between provinces with and without donor programs (141/322=43.8% versus 0/390=0%), but there were no differences in ROSC between the two types of provinces (418/1320=31.7% versus 652/1970=33.4%). CONCLUSIONS: Many potential donors are missed in current clinical practice. uDCD programs are few and underused even in a country with high rates of organ transplantation.

Management of eclampsia in the prehospital setting.

Eclampsia is an uncommon and serious condition, particularly in the pre-hospital setting. Immediate treatment is required and should include airway control, administration of oxygen, anti-epileptics and magnesium, hypertension control, and urgent delivery of the baby.

[Factors affecting the survival of transplants from donors after prehospital cardiac death]. / Factores que influyen en la evolución de los injertos de donantes tras muerte cardiaca extrahospitalaria.

OBJECTIVES: To evaluate factors that influence the survival of transplanted organs from donors after prehospital cardiac death. MATERIAL AND METHODS: Retrospective observational study of data collected from hospital emergency service records. Information included prehospital cardiac deaths evaluated as donors as well as patients who received transplants. RESULTS: Two hundred cases from 2008 through 2011 were studied. Sixty-nine potential donors (34.5%) were rejected. Three hundred organs were extracted from the remaining 131 donor cases, to yield a mean (SD) of 2.32 (0.83) transplanted organs/donor or 1.52 (1.29) organs/potential donor. One hundred fifty-two potential donors (76%) were treated with mechanical cardiopumps during transport. We detected no significant differences between cases transported with manual chest compressions and cases treated with cardiopumps regarding age (40.1 vs 43.5 years, P=.06), responder arrival times (13 min 54 s vs 12 min 54 s, P=.45), or transport times (1 h 27 min vs 1 h 32 min). However, case transported with manual chest compressions yielded significantly more kidneys (mean, 1.96/potential donor) than those transported with cardiopump compressions (mean, 1.38/potential donor) (P=.008). Eleven of the 229 kidneys harvested (4%) were not transplanted. The median (interquartile range) serum creatinine concentrations after kidney transplants at 6 and 12 months, respectively, were 1.37 (1.10-1.58) mg/dL and 1.43 (1.11-1.80) mg/dL. CONCLUSION: Our findings suggest that the use of a cardiopump reduces donor recruitment. Long-term creatinine levels are similar after transplantation of kidneys from donors transported with a cardiopump or with manual compressions.

OBJETIVO: Valorar los factores extrahospitalarios que pueden influir en la viabilidad de los injertos en los receptores. METODO: Estudio observacional retrospectivo que recoge datos de los registros del sistema de emergencias (pacientes con muerte cardiaca extrahospitalaria que fueron trasladados al hospital para valorar) y del hospital (pacientes trasplantados) de aquellos pacientes con muerte cardiaca extrahospitalaria que fueron trasladados al hospital para valorar. RESULTADOS: Se recogen 200 casos entre los años 2008 y 2011, de los que 69 (34,5%) no fueron donantes. De los 131 donantes utilizados se extrajeron 300 órganos [media de 2,32 (DE 0,83) órganos/donante utilizado y 1,52 (DE 1,29) órganos/donante potencial]. De los 200 pacientes, 152 fueron trasladados bajo cardiocompresión mecánica (76%). No hay diferencia significativa en edad (40,1 frente a 43,5 años, p = 0,06) y tiempo de llegada (13' 54' ' frente a 12' 54' ' , p = 0,45) y tiempo de trasferencia (1 h y 27' frente a 1 h y 32') entre el grupo de pacientes trasladados con cardiocompresión manual y con cardiocompresión mecánica, pero si en la media de órganos por donante potencial en favor de la cardiocompresión manual (1,96 frente a 1,38, p = 0,008). De los 229 riñones extraídos, no se trasplantaron 11 (4%). La mediana de la creatinina a los 6 meses de los riñones fue de 1,37 mg/dl (RIC: 1,10-1,58) y a los 12 meses de 1,43 mg/dl (RIC: 1,11-1,80), sin diferencias entre ambos grupos. CONCLUSIONES: Nuestros datos sugieren que el uso de compresores mecánicos disminuye el reclutamiento de donantes. A largo plazo la concentración de creatinina en los riñones trasplantados es similar independientemente del tipo de compresión usada durante el traslado y ninguna variable extrahospitalaria predice la evolución de los injertos.

Out-hospital donors after cardiac death in Madrid, Spain: a 5-year review.

OBJECTIVE: The Medical Emergencies Service of Madrid (Spain) (Servicio de Urgencias Medicas de Madrid), SUMMA112, forms part of an organ donor program involving patients who have suffered out-hospital cardiac arrest and fail to respond to advanced cardiopulmonary resuscitation maneuvers. Subjects meeting the inclusion criteria are moved to a transplant unit under sustained resuscitation maneuvering in order to harvest the organs. This paper presents compliance with the timelines of the program, the proportion of donors, the characteristics of donors and non-donors, and the number of organs obtained. MATERIAL: A retrospective descriptive study was made based on the review of case histories. The SPSS(©) version 16.0 statistical package was used for data analysis. RESULTS: A total of 214 cases were recorded, of which 84% were males. The mean age was 40 years. The mean time to arrival on scene was 13 min and 34 s. The mean time to arrival in hospital was 88 min and 10 s. A total of 522 organs and tissues were harvested (250 kidneys, 33 livers, 123 corneas, 97 bone tissues and 19 lungs), corresponding to 3.2 organs/tissues per patient on average. A total of 21.7% of the patients were not valid. There were no differences between the valid and non-valid patients in terms of age and gender. The causes of non-donation included extracorporeal circuit failure (6.3%), family refusal (15.6%), patient refusal expressed in life (4.7%), legal denial (1.6%), biological causes (51.6%), and others (20.3%). Cardiac compressors were used in 85 cases, yielding 92 kidneys, 41 corneas, 30 bone tissues, 19 livers and 9 lungs, corresponding to 2.1 organs/tissues per patient on average. CONCLUSION: This program affords a very important number of organs for transplantation. Further studies are needed to assess the efficacy of mechanical cardiac compressor use in generating more organs.
