Obstetric emergencies at the United States-Mexico border crossings in El Paso, Texas.

OBJECTIVE: To describe the frequency, characteristics, and patient outcomes for women who accessed Emergency Medical Services (EMS) for obstetric emergencies at the ports of entry (POE) between El Paso, Texas, United States of America, and Ciudad Juárez, Chihuahua, Mexico. METHODS: A descriptive study of women 12-49 years of age for whom an EMS ambulance was called to an El Paso POE location from December 2008-April 2011 was conducted. Women were identified through surveillance of EMS records. EMS and emergency department (ED) records were abstracted for all women through December 2009 and for women with an obstetric emergency through April 2011. For obstetric patients admitted to the hospital, additional prenatal and birth characteristics were collected. Frequencies and proportions were estimated for each variable; differences between residents of the United States and Mexico were tested. RESULTS: During December 2008-December 2009, 47.6% (68/143) of women receiving EMS assistance at an El Paso POE had an obstetric emergency, nearly 20 times the proportion for Texas overall. During December 2008-April 2011, 60.1% (66/109) of obstetric patients with ED records were admitted to hospital and 52 gave birth before discharge. Preterm birth (23.1%; No. = 12), low birth weight (9.6%; No. = 5), birth in transit (7.7%; No. = 4), and postpartum hemorrhage (5.8%; No. = 3) were common; fewer than one-half the women (46.2%; No. = 24) had evidence of prenatal care. CONCLUSIONS: The high proportion of obstetric EMS transports and high prevalence of complications in this population suggest a need for binational risk reduction efforts.

Objetivo. Describir la frecuencia, las características y los resultados asistenciales de las mujeres que recibieron atención médica de urgencia por problemas obstétricos en los puntos fronterizos entre El Paso (Texas, Estados Unidos) y Ciudad Juárez (Chihuahua, México). Métodos. Se realizó un estudio descriptivo de las mujeres de 12 a 49 años de edad para las que se solicitó una ambulancia de urgencia desde los puntos de ingreso de El Paso entre diciembre del 2008 y abril del 2011. Para identificar a las mujeres se hizo un seguimiento de los archivos de los servicios de urgencias. Se resumieron los historiales de los servicios de urgencias y del departamento de urgencias hasta diciembre del 2009 en el caso de todas las mujeres y hasta abril del 2011 en el caso de las mujeres con una urgencia obstétrica. Respecto a las pacientes ingresadas en hospitales por cuadros obstétricos, se recopilaron además las características prenatales y los datos del parto. Se calcularon las frecuencias y las proporciones relativas a cada variable; se analizaron las diferencias entre las residentes de los Estados Unidos y las de México. Resultados. En el período comprendido entre diciembre del 2008 y diciembre del 2009, 47,6% (68/143) de las mujeres atendidas de urgencia en un punto fronterizo de El Paso presentó una urgencia obstétrica, casi 20 veces la proporción correspondiente al estado de Texas en general. Entre diciembre del 2008 y abril del 2011, 60,1% (66/109) de las pacientes obstétricas con historial en el departamento de urgencias fueron ingresadas en un hospital y 52 dieron a luz antes de recibir el alta. Fueron frecuentes los partos prematuros (23,1%; No. = 12), el peso bajo al nacer (9,6%, No. = 5), los partos en tránsito (7,7%; No. = 4) y las hemorragias posparto (5,8%; No. = 3); en menos de la mitad de los casos (46,2%; No. = 24) no se constató que las mujeres hubiesen recibido asistencia prenatal. Conclusiones. La elevada proporción de transportes por urgencias obstétricas y la alta prevalencia de complicaciones en esta población ponen de manifiesto la necesidad de actuaciones binacionales para reducir los riesgos.
