Resumen: El objetivo fue analizar la oportunidad de la atención médica de emergencias (tiempo transcurrido desde que ocurrió la lesión hasta el primer contacto con el Sistema Médico de Emergencias -SME) y su relación con distintas consecuencias negativas en salud, en pacientes con lesiones causadas por el tránsito, atendidos en dos hospitales de México, uno en Guadalajara, Jalisco y otro en León, Guanajuato. Se utilizó información del Sistema de Vigilancia Epidemiológica de las Lesiones Causadas por el Tránsito, establecido como parte del Programa Global de Seguridad Vial de la Filantropía de Bloomberg. Se recabó información de todos los pacientes atendidos por lesiones causadas por el tránsito en dos hospitales de referencia, de mayo 2012 a noviembre 2014. Se realizó una regresión logística multinomial para modelar los resultados en salud, categorizados en estancia corta, hospitalización prolongada, discapacidad y defunción, con la oportunidad de la atención, ajustando por distintas variables de interés. 2.575 lesionados fueron analizados. La oportunidad de la atención fue 103,74min (± 231,36) en León y 75,37min (± 156,87) en Guadalajara, siendo 38,02 y 36,23min en quienes recibieron atención médica prehospitalaria, respectivamente. La oportunidad de la atención se asoció con una menor estancia hospitalaria prolongada, pero no con una menor incidencia de discapacidad o muerte. Recibir atención médica prehospitalaria estuvo asociado con consecuencias negativas en salud. Una atención oportuna está asociada a una menor posibilidad de tener hospitalizaciones prolongadas. Es necesario impulsar estrategias para evaluar, y eventualmente mejorar la calidad técnica de la atención médica prehospitalaria, incluyendo la oportunidad de la atención y la adecuada regulación.

Background Limited data from low- and middle-income countries (LMICs) on the severity of road traffic injuries (RTIs) and their relation to different variables of interest are routinely obtained. Knowledge on this subject relies on evidence from high-income countries, which might not be the same as in LMICs. This information is greatly needed to advance and inform local and regional efforts towards the United Nations’ Decade of Action and the Sustainable Development Goals. Methods From May 2012 to November 2014, a RTI surveillance system was implemented in two referral hospitals in two Mexican cities, León and Guadalajara, with the objective of exploring the relationship between Injury Severity Score (ISS) and different sociodemographic characteristics of the injured as well as different variables related to the event and the environment. All individuals suffering RTIs who visited the Emergency Rooms (ER) were included after granting informed consent. A Zero-Truncated Negative Binomial Model was employed to explore the statistical association between ISS and variables of interest. Results 3024 individuals participated in the study: 2185 (72.3%) patients from León and 839 patients (27.7%) from Guadalajara. Being male, in the 20–59 age-group, having less schooling, events occurring in Guadalajara, on Sundays, at night, and arriving at ER via public/private ambulance were all associated with an increased log count of ISS. Found a significant interaction effect (p-value< 0.05) between type of road user and alcohol intake six hours before the accident on severity of the injury (ISS). The use of illicit drugs, cellphones and safety devices during the event showed no association to ISS. Conclusions Our study contributes to the statistical analysis of ISS obtained through RTI hospital surveillance systems. Findings might facilitate the development and evaluation of focused interventions to reduce RTIs in vulnerable users, to enhance ER services and prehospital care, and to reduce drink driving.
Objetivo: Identificar las barreras que existen para la atención de las conductas suicidas, desde la perspectiva de las/los profesionales de la salud mental del primer nivel de atención de la Ciudad de México. Metodología: Estudio cualitativo exploratorio, basado en 35 entrevistas semiestructuradas, dirigidas a personal de salud de dos unidades de salud mental de referencia nacional. El análisis de la información se hizo mediante el Framework Analysis. Resultados: Las/los participantes consideraron que las conductas suicidas no han sido definidas como una prioridad dentro de los trastornos de salud mental. La ausencia de políticas públicas, la sobrecarga de trabajo, la falta de seguimiento a las/los pacientes, entre otras, fueron identificadas como barreras para una atención adecuada y oportuna. Conclusiones: Los programas de prevención de las conductas suicidas deben tomar en cuenta el contexto socioeconómico de la población y las características de los servicios de salud, así como las necesidades de las personas prestadoras de servicios de salud. Se requiere ampliar el entrenamiento profesional y mejorar el sistema de referencia y contrarreferencia entre los distintos niveles de atención.
BackgroundSpeeding is responsible for countless traffic collisions and road traffic injuries (RTIs) around the world. It threatens the lives of passengers in motor vehicles as well as the safety of other individuals sharing the public roads. Little evidence has been provided by low- and middle-income countries on speed transgression patterns.ObjectiveTo document the prevalence of speeding in motor vehicles with four or more wheels and to analyse the associated factors in four Mexican cities.MethodsWe conducted a cross-sectional study in the cities of Guadalajara-Zapopan, León, Cuernavaca and Villahermosa. Data on speed, drivers, vehicles, road infrastructure and the environment were collected from a randomly selected sample of urban road segments. We identified the factors associated with speeding through a logistic multiple regression model.ResultsWith an overall prevalence of 47% (95% CI 45.83 to 48.18), speeding occurred most frequently in Villahermosa (61.07%, 95% CI 59.10 to 63.01) as compared to León (51%, 95% CI 48.07 to 53.92), Cuernavaca (47.6%, 95% CI 45.35 to 49.85) and Guadalajara-Zapopan (20.76%, 95% CI 18.75 to 22.88). Speeding increased in the afternoons, on roads with numerous lanes, on Thursdays and Sundays and in foggy weather, but decreased in cities with speed control strategies and on roads with low visibility. No differences were observed between sexes or among age groups.ConclusionsEvidence from our study highlights the urgent need to implement speed control measures such as changes in road infrastructure and design, and to promote comprehensive speeding legislation aimed at reducing exposure to this important risk factor.
