Characteristics of digoxin toxicity attended in Spanish emergency departments according to type of poisoning and administration of digoxin antibodies: the DIGITOX study. / Características de las intoxicaciones por digoxina atendidas en diversos servicios de urgencias españoles en función del tipo de intoxicación y de la administración de anticuerpos antidigoxina: estudio DIGITOX.

OBJECTIVES: Digoxin toxicity accounts for a small percentage of poisonings attended by emergency departments. This study aimed to describe differences between acute and chronic digoxin toxicity and assess the use of digoxin-specific antibody fragments (digoxin-Fab) as an antidote. MATERIAL AND METHODS: Retrospective, observational, multicenter study in 15 hospital emergency departments in 8 Spanish autonomous communities in 7 years. We collected patient, clinical and treatment variables, and discharge destination. Patients were classified according to whether toxicity was acute or chronic and whether digoxin-Fab was administered or not. RESULTS: Twenty-seven acute and 631 chronic digoxin poisonings were attended. The mean (SD) patient age was 83.9 (7.9) years, and 76.9% were women. Patients with acute toxicity were younger (80.0 [12] years) than those with chronic toxicity (84.1 [7.7] years) (P .038), and accidental poisoning was less common (in 85.2% vs 100% in chronic toxicity; P .001). Cases of acute toxicity were also more serious (Poison Severity Score (29.6% vs 12.5% in chronic toxicity; P .001). Thirty-four patients were treated with digoxin-Fab (5.4%). These patients were younger (78.7 [11.5] years vs 84.2 (7.6) years), their toxicity was more often acute (in 20.6% vs 3.2% in chronic toxicity), more had attempted suicide (8.8% vs 0.2% with chronic toxicity), and more had severe symptoms (50% vs 11.2%) (P .001, all comparisons). Hospital admission was required for 76.1%. Overall, mortality was 11.4%. CONCLUSION: Chronic toxicity accounts for most digoxin poisoning cases, and most patients are women. Acute toxicity is more serious. Patients who required digoxin-Fab have more severe poisoning. Such patients usually have acute toxicity, and attempted suicide is more often the reason for the emergency.

OBJETIVO: Las intoxicaciones por digoxina representan un pequeño porcentaje de las intoxicaciones atendidas en urgencias. El objetivo de este estudio fue describir las diferencias entre intoxicaciones agudas y crónicas y evaluar la administración de su antídoto específico: los anticuerpos antidigoxina (AcAD). METODO: Estudio retrospectivo, observacional y multicéntrico en 15 servicios de urgencias hospitalarios de 8 comunidades autónomas durante 7 años. Se recogieron datos de filiación, clínica, tratamiento y destino al alta. Los pacientes se dividieron según era la intoxicación aguda o crónica y según recibían o no AcAD. RESULTADOS: Se recogieron 27 intoxicaciones agudas y 631 crónicas. La edad media fue de 83,9 (7,9) años, y el 76,9% eran mujeres. Los pacientes con intoxicación aguda tenían menor edad media (80,0 (12) vs 84,1 (7,7) años; p 0,038), y porcentaje de causa accidental (85,2% vs 100%; p 0,001) y mayor gravedad en la escala Poison Severity Score (29,6% vs 12,5%; p 0,001). Treinta y cuatro pacientes recibieron AcAD (5,4%) y constituyen un grupo de menor edad [78,7 (11,5) vs 84,2 (7,6); p 0,001], con mayor porcentaje de intoxicaciones agudas (20,6% vs 3,2%), intencionalidad suicida (8,8% vs 0,2%) y gravedad (50% vs 11,2%, p 0,001 en todas las comparaciones). El 76,1% precisó ingreso. La mortalidad fue del 11,4%. CONCLUSIONES: Las intoxicaciones por digoxina suelen ser crónicas y predominan en mujeres. Las intoxicaciones agudas son de mayor gravedad. Los pacientes que precisaron administración de AcAD tenían intoxicaciones más graves y mayor porcentaje de intoxicaciones agudas y con intencionalidad suicida.

Characteristics of drug poisonings treated in eleven Spanish emergency departments: Differentiated analysis by sex. / Características de las intoxicaciones por drogas atendidas en once servicios de urgencias españoles: Análisis diferenciado por sexo.

In order to identify the sociodemographic, clinical, emergency management and severity differences of drug poisoning treated in Emergency Departments (ED) from a gender perspective, data on patients from 11 Spanish EDs were recorded over 24 months (August 2017-July 2019). The severity of intoxication was compared by sex and was based on the combined adverse event (orotracheal intubation, cardiorespiratory arrest, intensive care hospitalization, and death). We included 4,526 patients (men 75.5%), with a mean age of 33 years. The most frequent drugs were: cocaine (47.8%), cannabis (44.4%) and amphetamines (25.5%). Men consumed more GHB (5.6% vs. 1.9%, p < .001) and less benzodiazepines (8.0% vs. 11.1%, p = .002) and alcohol (57.2% vs. 61.2%, p = .028) than women, with no differences in other types of drugs. Men presented significantly more severe bradycardia (OR = 4.39, 95%CI = 1.03-18.7), chest pain (OR = 1.72, 95%CI = 1.27-2.35) and symptomatic hypertension (OR = 1.56, 95%CI = 1.06-2.30) and less anxiety (OR = 0.74, 95%CI = 0.61-0.89) and vomiting (OR = 0.64, CI95% = 0.51-0.80). Men had more combined adverse events (3.1% vs. 2.0%, p = .047) and a greater intubations (1.9% vs. 1.0%, p = .044), with no significant differences in the adjusted model (OR = 1.349, 95%CI = 0.827-2.202 and OR = 1.371, 95%CI = 0.700-2.685, respectively). Twelve patients died (0.3%), with no differences according to sex. Drug intoxications attended in the ED differ according to sex. GHB, benzodiazepines and alcohol are more frequently involved in men than women. Cardiovascular symptomatology is more prevalent in men, while anxiety and vomiting are more frequent in women, which cannot be explained by differences in sociodemographic characteristics or the drugs used. There were no differences in the severity of the intoxication episodes.

Con el objetivo de identificar, con perspectiva de género, las diferencias sociodemográficas, clínicas, manejo en urgencias y gravedad de las intoxicaciones por drogas atendidas en Servicios de Urgencias Hospitalarias (SUH), se registraron todos los pacientes atendidos en 11 SUH españoles durante 24 meses (agosto 2017-julio 2019). La gravedad de la intoxicación se basó en el evento adverso combinado (intubación orotraqueal, parada cardiorrespiratoria, hospitalización en intensivos, y muerte), comparándose según el sexo. Cuando se encontraron diferencias significativas en sintomatología o gravedad, los resultados se ajustaron por características sociodemográficas y drogas consumidas. Se incluyeron 4.526 pacientes (hombres 75,5%), con edad media de 33 años. Las drogas más frecuentes fueron cocaína (47,8%), cánnabis (44,4%) y anfetaminas (25,5%). Hubo más GHB en hombres (5,6% vs 1,9%, p < ,001) y más benzodiacepinas (8,0% vs 11,1%, p = ,002) y alcohol (57,2% vs 61,2%, p = ,028) en mujeres, sin diferencias en otras de drogas. Los hombres tuvieron significativamente más bradicardia grave (OR = 4,39, IC95% = 1,03-18,7), dolor torácico (OR = 1,72, IC95% = 1,27-2,35) e hipertensión sintomática (OR = 1,56, IC95% = 1,06-2,30) y menos ansiedad (OR = 0,74, IC95% = 0,61-0,89) y vómitos (OR = 0,64, IC95% = 0,51-0,80). Tuvieron también más eventos adversos combinados (3,1% vs 2,0%, p = ,047) y más intubaciones (1,9% vs 1,0%, p = ,044), pero sin diferencias significativas en el modelo ajustado (OR = 1,349, IC95% = 0,827-2,202 y OR = 1,371, IC95% = 0,700-2,685, respectivamente). Fallecieron 12 pacientes (0,3%), sin diferencias según sexo. Concluimos que existen diferencias según el sexo en las drogas que originan intoxicaciones atendidas en los SUH. Las diferencias en sintomatología cardiovascular (más en hombres) y ansiosa o digestiva (más en mujeres) no se explican por diferencias sociodemográficas o de drogas utilizadas. La gravedad de la intoxicación no se ve influida por el sexo.

Detectability of Dissociative Psychoactive Substances in Urine by Five Commercial Phencyclidine Immunoassays.

Methoxetamine (MXE) and the arylcyclohexylamines 3-methoxy-PCP (3-MeO-PCP) and 4-methoxy-PCP (4-MeO-PCP) are substituted analogs of the dissociative psychoactive substances ketamine and phencyclidine (PCP), respectively. They have emerged on the new psychoactive substances (NPS) market as legal alternatives to these classically banned dissociatives. Little data has been published regarding the cross-reactivity of these NPS in PCP immunoassays (IAs). The aim of this work was to explore the possibilities of detecting 3-MeO-PCP, 4-MeO-PCP, MXE and ketamine in commercial IAs for PCP. The cross-reactivity study was performed in five different PCP IAs using urine-free, spiked samples and urine samples obtained from two 3-MeO-PCP overdose cases. 3-MeO-PCP and 4-MeO-PCP showed cross-reactivity (ranging from 1-143%) in all PCP IAs evaluated. MXE only showed very weak cross-reactivity (ranged from 0.04 to 0.25%) and ketamine was not detected in any PCP IA evaluated. Urine samples from the two overdose cases were positive for PCP in all IAs evaluated. The commercial PCP IAs evaluated exhibited utility as rapid, preliminary screening techniques for 3-MeO-PCP and 4-MeO-PCP, but not for ketamine. The low reactivity of MXE limits its detectability in the PCP IAs evaluated.

Comparación de las urgencias atendidas por drogas de abuso en dos servicios de urgencias españoles con las atendidas en tres áreas europeas distintas / Emergencies related to recreational drug abuse in Spain compared to emergencies attended in 3 European areas

Objetivo. Analizar algunas características epidemiológicas, clínicas y asistenciales de los pacientes atendidos por sintomatología directamente derivada del consumo de drogas de abuso en dos servicios de urgencias hospitalarios (SUH) españoles y compararlas con las observadas en otras regiones de Europa. Método. Análisis secundario del Registro Euro-DEN Plus (14 países europeos, 20 SUH) que incluyó todos los pacientes atendidos por sintomatología derivada del consumo de drogas (excepto etanol aislado) durante 39 meses consecutivos (octubre 2013 a diciembre 2016). Se comparan los casos de los 2 centros españoles (Barcelona, Palma) con los de 5 centros de Reino Unido e Irlanda (Islas Británicas -IB-), 6 del Norte de Europa (NE) y 7 de Europa Central (EC). Resultados. Se recogieron 17.104 pacientes: España 1.186, IB 6.653, NE 6.097 y EC 3.168. En España hubo más urgencias por cocaína (48,4%) y menos por opiáceos (12,4%) que en el resto de zonas; los pacientes eran más jóvenes (32,2 años) que en NE y mayores que en IB y EC; menos frecuentemente mujeres (21,9%) que en NE y EC; llegaron menos frecuentemente en ambulancia (70,0%) que en IB y NE; y en el SUH se registró escasamente la temperatura (29,8%) y frecuencia respiratoria (30,3%). Las manifestaciones clínicas difirieron entre zonas por la distinta prevalencia de cada tipo de droga. Naloxona (9,6%) se utilizó menos que en IB y NE, y flumazenilo (5,6%) más que en las otras zonas, y los porcentajes de ingresos (4,6%) y fugas del SUH (6,2%) fueron los menores de todas las regiones analizadas. La mortalidad, en urgencias (0,4%) y global (0,7%), fue significativamente superior que en NE. Conclusiones. Las características de las urgencias generadas por drogas de abuso son diferentes en España respecto a otras zonas europeas, debido a un diferente patrón de consumo. Su manejo en el SUH, en términos de exploraciones realizadas, tratamientos empleados y disposición tras la asistencia también son diferentes

Objectives. To analyze epidemiologic, clinical, and care characteristics in cases in which patients came to 2 Spanish emergency departments (EDs) with symptoms caused by recreational drug abuse. To compare the characteristics with those reported for other areas of Europe. Methods. Secondary analysis of the registry of the European Drug Emergencies Network (Euro-DEN Plus), which collects cases in 14 European countries and 20 EDs. The registry included all patients attending EDs with symptoms of recreational drug abuse (excepting cases involving alcohol alone) over a period of 39 consecutive months (October 2013 to December 2016). We compared the cases from the 2 Spanish EDs (in Barcelona and Palma de Mallorca) to those from the 5 EDs in Ireland and the UK, 6 in northern Europe, and 7 in central Europe. Results. A total of 17 104 patients' cases were included: Spain, 1186; UK and Ireland, 6653; northern Europe, 6097; and central Europe, 3168. Spain saw more emergencies related to cocaine (48.4%) and fewer related to opioids (12.4%) than the other areas. The Spanish patients were younger (32.2 years) on average than those in northern Europe and older than those in the UK and Ireland and central Europe. Fewer patients were women in Spain (21.9%) than in northern or central Europe. Fewer arrived in ambulances in Spain (70.0%) than in the UK and Ireland or northern Europe. The Spanish EDs recorded the temperature and respiratory frequency of fewer patients (29.8% and 30.3%, respectively). Clinical signs differed between geographical areas attributable to differences in drug-use patterns. In Spain, naloxone was used by fewer patients (9.6%) than in the UK and Ireland and northern Europe, and flumazenil was used by more patients (5.6%) than in other areas. Spain saw lower percentages of admissions (4.6%) and patients who left without an ED discharge (6.2%) in comparison with other areas. Mortality rates in the Spanish EDs (0.4%) and after discharge from them (0.7%) were higher than in northern Europe. Conclusions. The characteristics of emergencies related to recreational drug abuse registered by the Spanish EDs were differed from those registered in other parts of Europe due to different patterns of drug use. We also detected differences between the Spanish and other European EDs with respect to examinations or tests performed, treatment given, and discharge disposition

Intoxication by gamma hydroxybutyrate and related analogues: Clinical characteristics and comparison between pure intoxication and that combined with other substances of abuse.

OBJECTIVE: To study the profile of European gamma-hydroxybutyrate (GHB) and gammabutyrolactone (GBL) intoxication and analyse the differences in the clinical manifestations produced by intoxication by GHB/GBL alone and in combination with other substances of abuse. METHOD: We prospectively collected data on all the patients attended in the Emergency Departments (ED) of the centres participating in the Euro-DEN network over 12 months (October 2013 to September 2014) with a primary presenting complaint of drug intoxication (excluding ethanol alone) and registered the epidemiological and clinical data and outcomes. RESULTS: We included 710 cases (83% males, mean age 31 years), representing 12.6% of the total cases attended for drug intoxication. Of these, 73.5% arrived at the ED by ambulance, predominantly during weekend, and 71.7% consumed GHB/GBL in combination with other substances of abuse, the most frequent additional agents being ethanol (50%), amphetamine derivatives (36%), cocaine (12%) and cannabis (8%). Among 15 clinical features pre-defined in the project database, the 3 most frequently identified were altered behaviour (39%), reduced consciousness (34%) and anxiety (14%). The severity ranged from mild cases requiring no treatment (308 cases, 43.4%) to severe cases requiring admission to intensive care (103 cases, 14.6%) and mechanical ventilation (49 cases, 6.9%). No deaths were reported. In comparison with only GHB/GBL consumption, patients consuming GHB/GBL with co-intoxicants presented more vomiting (15% vs. 3%, p<0.001) and cardiovascular symptoms (5.3% vs. 1.5%, p<0.05), a greater need for treatment (59.8% vs. 48.3%, p<0.01) and a longer ED stay (11.3% vs. 3.6% patients with ED stay >12h, p<0.01). CONCLUSIONS: The profile of the typical GHB/GBL-intoxicated European is a young male, requiring care for altered behaviour and reduced level of consciousness, mainly during the weekend. The clinical features are more severe when GHB is consumed in combination with other substances of abuse.

Multicenter assessment of the revisit risk for a further drug-related problem in the emergency department in cocaine users (MARRIED-cocaine study).

INTRODUCTION AND OBJECTIVES: Emergency departments (EDs) in Spanish hospitals daily attend a large number of patients for adverse reactions or clinical complications resulting from cocaine use. After discharge, some of these patients revisit the ED for the same reason within a year. The objective of the present study was to quantify the rate of such revisits and identify the factors associated with them. METHOD: We performed a retrospective, multicenter study with cohort follow-up and without a control group, conducted in the EDs of six Spanish hospitals during 12 months (January-December 2009). We included all ED patients attended for cocaine-related symptoms who reported recent cocaine use and those with cocaine-positive urine analysis by immunoassay without declared consumption. Twelve independent variables assessed for each hospital ED were collected: sex, age, place of consumption, month, day, and time of consumption, mode of arrival at the ED, discharge diagnosis, psychiatric assessment on the ED episode, concomitant drugs, destination on discharge, and history of previous ED visits related with drug use and alcohol use. The dependent variable was a subsequent visit to the ED associated with drug use, identified using the computerized hospital admissions system. RESULTS: The study included 807 patients, of whom 6.7% revisited the ED within 30 days, 11.9% within 3 months and 18.9% within 1 year. The variables significantly associated with ED revisits were: presence of clinical manifestations directly related to cocaine (p < 0.05), ED attendance on a working day (p < 0.05), history of ED visits related with the consumption of alcohol (p < 0.001) or drugs (p < 0.001), and the need for urgent consultation with a psychiatrist (p < 0.001), although only the last four were independent predictors in multivariate analysis. We derived a score based on these variables to predict risk of revisits (MARRIED-score, ranging from 0 to 400 points), which had a reasonably good predictive value for revisit (area under ROC of 0.75; 95% CI 0.71-0.79).

Indicadores de calidad para la asistencia urgente de pacientes con intoxicaciones agudas (Calitox-2006) / Quality indicators for emergency health care of patients with acute poisoning (Calitox, 2006)

Se presenta un mapa de 24 indicadores para medir la calidad de la asistencia dada a los pacientes con intoxicaciones agudas que son atendidos en los servicios de urgencias. Se incluyen indicadores estructurales (disponibilidad de protocolos, stock de antídotos, técnicas analíticas, sondas de lavado gástrico), indicadores de proceso (adecuación de las técnicas de descontaminación digestiva, indicaciones de depuración renal y de depuración extrarrenal, uso de antídotos, indicación de análisis toxicológicos, práctica de electrocardiograma, demora asistencial, consulta psiquiátrica, parte judicial), indicadores de resultado (mortalidad, cumplimentación de un conjunto mínimo de datos del intoxicado, formación continuada del personal) e indicadores administrativos (publicaciones)

We present a map of 24 indicators to measure the quality of care given to patients with acute poisoning attended in the emergency department. These include structural indicators (availability of protocols, stocks of antidotes, analytical tests, gastric lavage tubes), process indicators (correct indication of gut decontamination techniques, indications for renal and extra-renal purification, use of antidotes, indication of toxicological analyses, ECG, delays in care, psychiatric referrals, judicial notifications), indicators of results (mortality, compliance with minimum basic data set of poisonings, continuing staff education) and administrative indicators (publications)
