Performance of 3 frailty scales for predicting adverse outcomes at 30 days in older patients discharged from emergency departments. / Rendimiento de tres escalas de fragilidad para predecir resultados adversos a 30 días en los pacientes mayores dados de alta en los servicios de urgencias.

OBJECTIVES: To compare the ability of 3 frailty scales (the Clinical Frailty Scale [CFS], the Functional Index - eMergency [FIM], and the Identification of Seniors at Risk [ISAR] scale) to predict adverse outcomes at 30 days in older patients discharged from hospital emergency departments (EDs). MATERIAL AND METHODS: Secondary analysis of data from the FRAIL-Madrid registry of patients aged 75 years or older who were discharged from Madrid EDs over a period of 3 months in 2018 and 2019. Frailty was defined by a CFS score over 4, a FIM score over 2, or an ISAR score over 3. The outcome variables were revisits to an ED, hospitalization, functional decline, death, and a composite variable of finding any of the previously named variables within 30 days of discharge. RESULTS: A total of 619 patients were studied. The mean (SD) age was 84 (7) years, and 59.1% were women. The CFS identified as frail a total of 339 patients (54.8%), the FIM 386 (62.4%), and the ISAR 301 (48.6%). An adverse outcome occurred within 30 days in 226 patients (36.5%): 21.5% revisited, 12.6% were hospitalized, 18.4% experienced functional decline, and 3.6% died. The areas under the receiver operating characteristic curves were as follows: CFS, 0.66 (95% CI, 0.62-0.70; P = .022); FIM, 0.67 (95% CI, 0.62-0.71; P = .021), and ISAR, 0.64 (95% CI, 0.60-0.69; P = .023). Adjusted odds ratios (aOR) showed that frailty was an independent risk factor for presenting any of the named adverse outcomes: aOR for CFS >4, 3.18 (95% CI, 2.02-5.01), P .001; aOR for FIM > 2, 3.49 (95% CI, 2.15-5.66), P .001; and aOR for ISAR >3, 2.46 (95% CI, 1.60-3.79), P .001. CONCLUSION: All 3 scales studied - the CFS, the FIM and the ISAR - are useful for identifying frail older patients at high risk of developing an adverse outcome (death, functional decline, hospitalization, or revisiting the ED) within 30 days after discharge.

OBJETIVO: Comparar la capacidad de tres escalas de fragilidad, Clinical Frailty Scale (CFS), Functional Index ­ eMergency (FIM) e Identification Senior at Risk (ISAR), para predecir resultados adversos (RA) a 30 días en los pacientes mayores dados de alta desde el servicio de urgencias hospitalario (SUH). METODO: Análisis secundario del registro FRAIL-Madrid que incluyó pacientes 75 años dados de alta de 10 SUH de Madrid durante un periodo de 3 meses entre 2018 y 2019. Se definió fragilidad como CFS 4, FIM 2 e ISAR 3. Las variables de resultado fueron revisita en urgencias, hospitalización, deterioro funcional, muerte y la variable compuesta por algún RA de los anteriores en los 30 días posteriores al alta del SUH. RESULTADOS: Se incluyeron 619 pacientes, la edad media fue de 84 años (DE 7), 59,1% eran mujeres. Hubo 339 pacientes (54,8%) identificados como frágiles en el SUH según CFS 4, 386 (62,4%) según FIM 2 y 301 (48,6%) según ISAR 3. Hubo 226 pacientes (36,5%) que presentaron algún RA a los 30 días tras el alta (21,5% revisita, 12,6% hospitalización,18,4% deterioro funcional y 3,6% muerte). El área bajo la curva (ABC) de la escala CFS fue de 0,66 (0,62-0,70; p = 0,022), de FIM 0,67 (0,62-0,71; p = 0,021) y de ISAR 0,64 (0,60-0,69; p = 0,023). La presencia de fragilidad fue un factor independiente de presentar algún RA a los 30 días tras el alta (CFS 4 ORa 3,18 [IC 95% 2,02-5,01, p 0,001], FIM 2 ORa 3,49 [IC 95% 2,15-5,66, p 0,001] e ISAR 3 ORa 2,46 [IC 95% 1,60-3,79, p 0,001]). CONCLUSIONES: Las tres escalas estudiadas ­CFS, FIM, ISAR­ son útiles y tienen una capacidad similar para identificar al paciente mayor frágil dado de alta del SUH con alto riesgo de presentar RA (muerte, deterioro funcional, hospitalización o revisita al SUH) a los 30 días.

Immune thrombotic thrombocytopenic purpura: clinical suspicion and basic management in emergency departments - an expert review and consensus statement from the Spanish societies of hematology and hemotherapy (SEHH) and emergency medicine (SEMES). / Púrpura trombocitopénica trombótica inmune: sospecha y manejo básico en los servicios de urgencias. Revisión y consenso de un grupo de expertos de las sociedades científicas SEHH y SEMES.

TEXT: Acquired or immune thrombotic thrombocytopenic purpura (TTP) are thrombotic microangiopathies associated with high mortality if treatment is not started early. Onset is usually sudden, meaning that the condition is often diagnosed in hospital emergency departments, where TTP must be suspected as early as possible. These guidelines were drafted by specialists in emergency medicine and hematology to cover the diagnosis, referral, and treatment of patients suspected of immune-mediated TTP who require emergency care. Immune TTP should be suspected whenever a patient presents with hemolytic microangiopathy and has a negative Coombs test, and thrombocytopenia, possibly in conjunction with fever and neurologic and cardiac alterations. If one of the existing diagnostic algorithms indicates there is a high probability that the patient has immune TTP, plasma exchange therapy should be started along with immunosuppressants. Treatment with caplacizumab should also be considered. The patient should be referred immediately to the hematology department within the same hospital or a referral hospital.

TEXTO: La púrpura trombótica trombocitopénica adquirida o inmune (PTTi) es una microangiopatía trombótica (MAT) con una elevada mortalidad si no se instaura un tratamiento precoz. El inicio habitualmente brusco de la enfermedad hace que, en la mayoría de los pacientes, el diagnóstico inicial se haga en los servicios de urgencias hospitalarios (SUH), donde se debe sospechar esta entidad con la mayor inmediatez posible. Esta guía, elaborada por profesionales de Medicina de Urgencias y de Hematología, establece unas recomendaciones en cuanto al diagnóstico, derivación y tratamiento de los pacientes con sospecha de PTTi en los SUH. Se debe sospechar PTTi en todo paciente que presente una anemia hemolítica microangiopática, prueba de Coombs directo negativa y trombocitopenia pudiendo asociar, además, fiebre, alteraciones neurológicas y cardiacas. Si tras la aplicación de alguno de los algoritmos diagnósticos existentes, hay una alta probabilidad de que el paciente presente una PTTi, debería iniciarse tratamiento con recambio plasmático, inmunosupresores y valorar el inicio de caplacizumab. Además, debe gestionarse el traslado inmediato de los pacientes al Servicio de Hematología, bien del mismo centro o a uno de referencia.

Pulmonary embolism in patients with COVID-19: incidence, risk factors, clinical characteristics, and outcome.

AIMS: We investigated the incidence, risk factors, clinical characteristics, and outcomes of pulmonary embolism (PE) in patients with COVID-19 attending emergency departments (EDs), before hospitalization. METHODS AND RESULTS: We retrospectively reviewed all COVID-19 patients diagnosed with PE in 62 Spanish EDs (20% of Spanish EDs, case group) during the first COVID-19 outbreak. COVID-19 patients without PE and non-COVID-19 patients with PE were included as control groups. Adjusted comparisons for baseline characteristics, acute episode characteristics, and outcomes were made between cases and randomly selected controls (1:1 ratio). We identified 368 PE in 74 814 patients with COVID-19 attending EDs (4.92‰). The standardized incidence of PE in the COVID-19 population resulted in 310 per 100 000 person-years, significantly higher than that observed in the non-COVID-19 population [35 per 100 000 person-years; odds ratio (OR) 8.95 for PE in the COVID-19 population, 95% confidence interval (CI) 8.51-9.41]. Several characteristics in COVID-19 patients were independently associated with PE, the strongest being D-dimer >1000 ng/mL, and chest pain (direct association) and chronic heart failure (inverse association). COVID-19 patients with PE differed from non-COVID-19 patients with PE in 16 characteristics, most directly related to COVID-19 infection; remarkably, D-dimer >1000 ng/mL, leg swelling/pain, and PE risk factors were significantly less present. PE in COVID-19 patients affected smaller pulmonary arteries than in non-COVID-19 patients, although right ventricular dysfunction was similar in both groups. In-hospital mortality in cases (16.0%) was similar to COVID-19 patients without PE (16.6%; OR 0.96, 95% CI 0.65-1.42; and 11.4% in a subgroup of COVID-19 patients with PE ruled out by scanner, OR 1.48, 95% CI 0.97-2.27), but higher than in non-COVID-19 patients with PE (6.5%; OR 2.74, 95% CI 1.66-4.51). Adjustment for differences in baseline and acute episode characteristics and sensitivity analysis reported very similar associations. CONCLUSIONS: PE in COVID-19 patients at ED presentation is unusual (about 0.5%), but incidence is approximately ninefold higher than in the general (non-COVID-19) population. Moreover, risk factors and leg symptoms are less frequent, D-dimer increase is lower and emboli involve smaller pulmonary arteries. While PE probably does not increase the mortality of COVID-19 patients, mortality is higher in COVID-19 than in non-COVID-19 patients with PE.

Inhaled Methoxyflurane Provides Greater Analgesia and Faster Onset of Action Versus Standard Analgesia in Patients With Trauma Pain: InMEDIATE: A Randomized Controlled Trial in Emergency Departments.

STUDY OBJECTIVE: The objective of the InMEDIATE study was to evaluate the change in intensity of traumatic pain over the first 20 min in adult patients treated with methoxyflurane versus standard analgesic treatment in Spain. This the first randomized, active-controlled, multicenter trial of methoxyflurane in the emergency setting in Europe. METHODS: This was a randomized, controlled study that enrolled adult patients with acute moderate to severe (score ≥4 on the 11-point Numeric Rating Scale) trauma-associated pain in 14 Spanish emergency departments. Patients were randomized 1:1 to methoxyflurane (up to 2×3 mL) or standard analgesic treatment. Coprimary endpoints were the change from baseline in Numeric Rating Scale pain intensity score during the first 20 minutes of treatment and time to first pain relief. RESULTS: Three hundred five patients were randomized (methoxyflurane 156; standard analgesic treatment 149). Most patients in the standard analgesic treatment group (70%) received intravenous first-step analgesics and 9.4% of patients were treated with opioids. Mean decrease from baseline in Numeric Rating Scale pain intensity score was greater for methoxyflurane than standard analgesic treatment at all points, with a significant treatment difference overall up to 20 minutes (repeated-measures model 2.47 versus 1.39; treatment difference 1.00; 95% confidence interval 0.84 to 1.32). Median time to first pain relief was significantly shorter for methoxyflurane than standard analgesic treatment (3 versus 10 minutes). Methoxyflurane achieved better patient and clinician ratings for pain control and comfort of treatment than standard analgesic treatment and exceeded patient and clinician expectations of treatment in, respectively, 77% and 72% of cases compared with 38% and 19% for standard analgesic treatment. CONCLUSION: These results support consideration of methoxyflurane as a nonnarcotic, easy-to-administer, rapid-acting, first-line alternative to currently available analgesic treatments for trauma pain.

[Physical structure, human resources, and health care quality indicators in public hospital emergency departments in the autonomous communities of Madrid and Catalonia: a comparative study]. / Estudio comparativo de la estructura física, recursos humanos e indicadores de actividad asistencial entre los servicios de urgencias hospitalarios públicos de las comunidades autónomas de Madrid y Cataluña.

OBJECTIVES: To compare the general, structural, and organizational characteristics of public hospital emergency departments in the Spanish autonomous communities of Madrid and Catalonia. MATERIAL AND METHODS: Descriptive survey-based study covering 3 areas of inquiry: general hospital features (18 questions), structural features of the emergency department (14 questions), and organizational and work-related policies of the emergency department (30 questions). Hospitals were grouped according to complexity: local hospitals (level 1), high-technology or referral hospitals (levels 2-3). RESULTS: We studied 26 hospital departments in Madrid (21, levels 2-3; 5, level 1) and 55 in Catalonia (24, levels 2-3; 31, level 1). Hospitals in Madrid are in newer buildings (P=.002), have more beds on conventional wards and in critical care units (P<.001, both comparisons), are more often affiliated with a university (P<.001), and serve larger populations (P=.027). The emergency departments in Madrid have larger surface areas available for clinical care and more cubicles for preliminary evaluations and observation beds (P=.001, all comparisons). Hospitals in Madrid also attended a larger median number of emergencies (P<.001). More physicians were employed in Catalonia overall, but the numbers of physician- and nurse-hours per hospital were higher in Madrid, where it was more usual for physicians to work exclusively in the emergency department (92.5% in Madrid vs 56.8% in Catalonia, P<.001). However, fewer of the employed physicians had permanent contracts in Madrid (30.5% vs 75.1% in Catalonia, P<.001). The ratio of resident physicians to staff physicians differs between the 2 communities on afternoon/evening, night, and holiday shifts (3:1 in Madrid; 1:1 in Catalonia). CONCLUSION: The physical and functional structures of hospital emergency departments in the communities of Madrid and Catalonia differ significantly. The differences cannot be attributed exclusively to geographic location.

OBJETIVO: Comparar las características generales, estructurales y organizativas de los servicios de urgencias de hospitales públicos (SUHP) de la Comunidad de Madrid con los de Cataluña. METODO: Estudio descriptivo tipo encuesta estructurada con 3 apartados: aspectos generales del hospital (18 preguntas), aspectos generales y estructurales de urgencias (14 preguntas), y aspectos organizativos y laborales de urgencias (30 preguntas). Los centros se agruparon según complejidad: niveles I-hospital comarcal y niveles II y III-hospital de alta tecnología o de referencia. RESULTADOS: Se incluyeron los 26 SUHP de la Comunidad de Madrid (21 nivel II-III y 5 nivel I), y 55 de Cataluña (24 nivel II- III y 31 nivel I). En Madrid, comparada con Cataluña: los hospitales son de construcción más reciente (p = 0,002); tienen mayor número de camas de hospitalización (p < 0,001) y de cuidados críticos (p < 0,001); están más frecuentemente vinculados a la universidad (p < 0,001) y cubren mayor población (p = 0,027). Los servicios de urgencias: tienen mayor superficie para la actividad clínica (p < 0,001) y la primera asistencia (p < 0,001); mayor número de puestos de primera asistencia (p < 0,001) y camas de observación (p = 0,001) y la mediana del número de atenciones urgentes es mayor (p < 0,001). De forma global, hay más facultativos contratados en Cataluña, pero el número de horas de médico y enfermera contratadas por centro es mayor en Madrid, donde los médicos suelen realizar su actividad exclusivamente en urgencias (92,5% frente a 56,8%; p < 0,001), muy pocos con contrato fijo indefinido (30,5% frente a 75,1%; p < 0,001) con relación médico residente/adjunto diferente en turnos de tarde, noche y días festivos en comparación con los SUHP catalanes (3:1 frente a 1:1). CONCLUSIONES: La estructura física y funcional de los SUHP madrileños y catalanes difiere de forma significativa sin que pueda explicarse, exclusivamente, por los aspectos geográficos.

[Multicenter, triple-blind randomized placebo controlled trial of adjuvant nitrous oxide 50% in oxygen 50%: efficacy for reducing pain and increasing satisfaction in patients treated for renal colic in the emergency department]. / Ensayo clínico aleatorizado triple ciego y multicéntrico para evaluar la eficacia en la disminución del dolor y el grado de satisfacción de una mezcla de óxido nitroso y oxígeno (N2O/O2) 50/50 como tratamiento añadido al convencional en los pacientes atendidos por cólico nefrítico en el servicio de urgencias.

OBJECTIVES: To assess the efficacy of a nitrous oxide and oxygen mixture (N2O/O2 50/50) for reducing pain and increasing satisfaction in patients with an initial clinical diagnosis of renal colic in the emergency department. MATERIAL AND METHODS: Multicenter, triple-blind randomized placebo-controlled trial. We randomized 147 patients with a clinical diagnosis of renal colic to an experimental group to receive the N2O/O2 50/50 mixture (n = 70) or a control group to receive 50% oxygen in air (n = 77). Both groups also received conventional analgesia with dexketoprofen plus metamizol and opiates administered sequentially until pain was brought under control; rescue doses of opioids were also available. The endpoints were the reduction in pain intensity expressed on a visual analog scale (VAS) 5 minutes after the start of treatment and the patient's level of satisfaction with treatment on discharge. RESULTS: The mean (SD) reduction in pain 5 minutes after starting analgesic treatment was 1.84 (2.05) VAS points in the intervention group and 1.67 (1.91) in the placebo group. The difference was not significant (P = .603). Neither were between-group differences significant at other pain evaluation times (10, 15, 30, and 60 minutes). Treatment was considered satisfactory (􀀀 9 on a VAS) by 53 of the 70 intervention-group patients (75.7%) and 56 of the 77 (72.7%) placebo-group patients (P = .412). Adverse effects appeared in 33 of the 70 patients (48.5%) who received the N2O/O2 mixture and in 19 patients (24.7%) who received the placebo (P = .003). CONCLUSION: The addition of N2O/O2 50/50 to standard analgesic therapy does not enhance the efficacy of pain control or the satisfaction of patients treated for renal colic in the emergency department.

OBJETIVO: Evaluar la eficacia en la disminución del dolor y el grado de satisfacción de una mezcla de óxido nitroso y oxígeno al 50% (N2O/O2 50/50) añadido al tratamiento convencional en los pacientes atendidos con sospecha de cólico nefrítico en los servicios de urgencias (SU). METODO: Ensayo clínico aleatorizado triple ciego controlado con placebo multicéntrico. Se incluyeron 147 pacientes con el diagnóstico clínico de cólico nefrítico a grupo experimental con N2O/O2 50/50 (N = 70) o grupo control con una mezcla de aire medicinal con una proporción de oxígeno del 50% (N = 77). Ambos grupos recibieron el tratamiento convencional con dexketoprofeno, al que se añadió metamizol y opioides administrados de forma secuencial en caso de no control del dolor, así como medicación de rescate con opioides. La variable de resultado principal fue la reducción en la intensidad de dolor, según la escala visual analgésica (EVA), a los 5 minutos de inicio del tratamiento y el grado de satisfacción del paciente con el tratamiento administrado previo al alta. RESULTADOS: El descenso del dolor medido por la EVA a los 5 minutos de iniciado el tratamiento fue de media 1,84 (DE 2,05) en el grupo tratado con N2O/O2 50/50 y de 1,67 (DE 1,91) en el grupo que recibió el placebo (p = 0,603). Tampoco se encontraron diferencias a los 10, 15, 30 y 60 minutos. La satisfacción con el tratamiento al alta se consideró adecuada (ô€€€ 9) en 53 de 70 pacientes (75,7%) en el grupo de N2O/O2 y en 56 de 77 (72,7%) en el grupo placebo (p = 0,412). Treinta y tres pacientes (48,5%) en el grupo N2O/O2 y 19 pacientes (24,7%) en el grupo placebo presentaron uno o más efectos secundarios (p = 0,003). CONCLUSIONES: La adición de N2O/O2 50/50 al tratamiento estándar no ha demostrado una mayor eficacia en el control del dolor ni en la satisfacción del paciente con un diagnóstico clínico de cólico nefrítico en el SU.

[Prevalence of undiagnosed human immunodeficiency virus infection in an emergency department and the characteristics of newly diagnosed patients]. / Prevalencia y características de los pacientes con infección por virus de la inmunodeficiencia humana (VIH) diagnosticados de novo en un servicio de urgencias.

OBJECTIVES: To estimate the prevalence of undiagnosed human immunodeficiency virus (HIV) infection detected by routine testing of patients seeking care in an emergency department and to describe the characteristics associated with new HIV-infection diagnosis. MATERIAL AND METHODS: Walk-in patients between the ages of 15 and 75 years who required a blood test were included. Routine fourth-generation enzyme-linked immunoassays were performed to detect HIV infection in all samples extracted. Patients with positive results were referred to the infectious diseases department for monitoring and treatment. RESULTS: Blood samples for 1722 patients were analyzed. Twenty-one patients (1.2%) refused to allow their samples to be tested; 19 more samples (1.1%) could not be tested. The prevalence of undiagnosed HIV infection among the remaining 1682 remaining patients was 0.6% (95% CI, 0.23%-0.96%). The prevalence tended to be nonsignificantly higher among patients born outside Spain (0.97% [95% CI, 0.3%-2.20%]) and in 36-50-year-olds (1.46% [95% CI, 0.4%-2.5%]). Characteristics associated with undiagnosed HIV infection were male sex (odds ratio [OR], 5.78 [95% CI, 1.0-31.4]), presenting with a chief complaint that suggested infection (OR, 8.14 [95% CI, 1.6-41.4]), and a history of hepatitis (OR, 5.53 [95% CI, 1.1-27.7]). CONCLUSION: The prevalence of undiagnosed HIV infection in our emergency department was high at 0.6%. The rate of patient acceptance of routine HIV testing was high. Strategies that target improving the detection of undiagnosed HIV infection are advisable.

OBJETIVO: Estimar la prevalencia de la infección por el virus de la inmunodeficiencia humana (VIH) no diagnosticada entre la población que acude al servicio de urgencias hospitalario (SUH) mediante la realización rutinaria del test para VIH, y describir los factores asociados al diagnóstico. METODO: Estudio descriptivo transversal que incluyó a los pacientes entre 15 y 75 años valorados en la zona de pacientes ambulantes del SUH y a los que se les realizó una analítica sanguínea por su motivo de consulta, en la que se obtuvo una muestra para realizar la prueba del VIH de manera rutinaria mediante test de enzimoinmunoanálisis (EIA) de 4ª generación. Los pacientes con resultado positivo fueron remitidos al servicio de infecciosas para seguimiento y tratamiento. RESULTADOS: Se obtuvieron muestras de sangre de 1.722 pacientes. De estos, 21 (1,2%) rechazaron la realización de la serología y 19 (1,1%) no fueron finalmente analizados. La prevalencia de infección VIH no diagnosticada entre los 1.682 pacientes analizados fue del 0,6% [IC 95%: 0,23-0,96%]. Fue, sin significación estadística, mayor en los pacientes nacidos en otros países 0,97% [IC 95%: 0,3-2,20] y en los pacientes de 36 a 50 años 1,46% [IC 95%: 0,4-2,5]. Los factores que se asociaron con infección no conocida por VIH fueron ser hombre [OR: 5,78 (IC 95%: 1,0-31,4)], tener un motivo de consulta sugerente de infección [OR: 8,14 (IC 95%: 1,6-41,4)] y tener antecedentes de hepatitis [OR: 5,53 (IC 95%: 1,1-27,7)]. CONCLUSIONES: Hubo una alta prevalencia (0,6%) de infección por VIH no diagnosticada entre los pacientes atendidos en urgencias, los cuales mostraron una alta aceptación para realizar una serología VIH de manera rutinaria y universal. Estos resultados aconsejan mejorar las estrategias de detección de infección oculta por VIH.
