Folletos de información educativa en migraña: satisfacción percibida en un grupo de pacientes / Migraine education brochures and patient-perceived satisfaction

Introducción: Los folletos informativos son una herramienta educativa habitual en la práctica neurológica diaria; mediante este mecanismo se pretende incrementar de primera mano los conocimientos que la población tiene sobre una enfermedad concreta, además de evitar fuentes de información erróneas. Las encuestas son el medio más empleado para conocer la satisfacción de los usuarios con los servicios recibidos. Objetivos: Evaluar la satisfacción percibida y establecer una retroalimentación informativa que valore la comprensión y la utilidad global de un folleto educativo sobre migraña. Material y métodos: Estudio abierto, prospectivo y multicéntrico sobre una población de pacientes diagnosticados de migraña en diversas consultas de neurología de la provincia de Alicante. En la visita basal se les entrega un folleto informativo de migraña confeccionado por el grupo de estudio para la cefalea de la Sociedad Valenciana de Neurología (CEFALIC). En la visita control se les solicita la cumplimentación de una encuesta personal y por escrito sobre la calidad global de la información incluida en el folleto. Resultados: Se incluye a un total de 257 pacientes diagnosticados de migraña (83% migraña episódica; 17% migraña crónica), con una edad media de 37,6 años. Confirmaron la lectura del folleto 207 paciente (80,5%) y no lo habían leído 50 pacientes (19,5%), bien por olvido bien por desinterés. Al 90% de los pacientes la lectura del folleto les pareció interesante y comprensible. El 76% de los encuestados opina que la lectura del folleto incrementa sus conocimientos sobre migraña. El 50% de los pacientes opina que el folleto resultó de utilidad para mejorar el control de su migraña. Conclusiones: La utilización de un folleto educativo sobre migraña resultó comprensible, además incrementó el conocimiento global de la enfermedad y en opinión de los pacientes resultó útil para mejorar el control de su migraña. La evaluación de la información educativa que prestamos a nuestros pacientes con migraña debe ser medida para descubrir las causas de descontento, determinar el nivel de calidad del servicio e investigar las posibilidades de mejora de calidad

Introduction: Brochures are commonly used as educational tools in daily neurological practice. They are provided to increase the general population's knowledge of a specific disease and also to combat sources of erroneous information. Surveys are the most commonly used method of ascertaining user satisfaction with services received. Objectives: This study will assess patient-perceived satisfaction and provide feedback to measure the comprehensibility and overall utility of an educational brochure on migraine. Material and methods: Open prospective multicentre study of a group of patients diagnosed with migraine in neurology clinics in Alicante province. During the initial visit, each patient received a migraine brochure prepared by the Valencian Society of Neurology's study group for headaches (CEFALIC). During a follow-up visit, they were then asked to fill out a personal survey on the overall quality of the information in the brochure. Results: We included a total of 257 patients diagnosed with migraine (83% episodic migraine; 17% chronic migraine); mean age was 37.6 years. Two hundred seven patients confirmed having read the brochure (80.5%); 50 patients (19.5%) either forgot to read it or had no interest in doing so. The brochure seemed interesting and easy to understand according to 90% of the patients. Seventy-six per cent of the respondents stated that reading the brochure increased their overall knowledge of migraine, while 50% of the patients found the brochure useful for improving migraine control. Conclusions: Patients found the migraine educational brochure to be comprehensible, a means of increasing overall knowledge of the disease, and useful for increasing control over migraines. Evaluations of the educational brochures that we provide to our patients with migraine should be studied to discover the causes of dissatisfaction, determine the level of quality of service, and investigate potential areas for improvement

[A descriptive study of neurocysticercosis in a tertiary care hospital]. / Estudio descriptivo de neurocisticercosis en un hospital terciario.

INTRODUCTION: Neurocysticercosis is the most frequent parasitic disease affecting the central nervous system. It is a disease that is endemic to certain countries in South America. The phenomenon of immigration, however, has increased its prevalence in developed regions due to the arrival of immigrants from endemic areas. AIM: To present the clinical and demographic characteristics of the cases of neurocysticercosis attended in a tertiary care hospital in the city of Murcia. PATIENTS AND METHODS: We conducted a descriptive, retrospective study by reviewing the medical records of patients with a hospital diagnosis of neurocysticercosis over a nine-year period (1997-2005). Demographic and clinical data on these patients were collected. RESULTS: Twenty-three patients (three under 12 years of age) were found. Mean age: 29.6 years. Countries of origin: Ecuador and Bolivia. The most frequently observed clinical manifestations were: epileptic seizures (73.9%), headache (39.1%) and neurological focus (26.1%). Albendazole was employed in 91.3% of cases and corticoids in 73.9%. The most frequently used drug in patients who received antiepileptic therapy was phenytoin. Four patients required surgical treatment. During the follow-up period, 52.8% of the patients were asymptomatic. CONCLUSIONS: Neurocysticercosis is a disease that is becoming increasingly more prevalent in Spain and we should suspect its presence in patients from endemic areas who visit because of clinical symptoms involving the central nervous system.

[Rendu-Osler-Weber disease as an infrequent cause of stroke]. / Enfermedad de Rendu-Osler-Weber como causa infrecuente de ictus.

INTRODUCTION: Hereditary haemorrhagic telangiectasia, or Rendu-Osler disease, is a congenital vascular disease that is associated with the presence of arteriovenous fistulas that cause paradoxical embolisms. CASE REPORT: An 83-year-old female with clinical signs and symptoms of convulsive attacks and multiple cerebral infarctions in the acute phase. She also presented a history of multiple haemorrhages and iron deficiency anaemia with no clear aetiological causation. A thorough examination of her medical history revealed a family history of haemorrhages and a sister who had been diagnosed with Rendu-Osler disease, which suggested the possible existence of a pulmonary arteriovenous fistula as the aetiological causation of her cerebrovascular disease. Neurovascular Doppler ultrasonography with bubble contrast test was positive, and the presence of the fistula was confirmed by a computerised axial tomographic angiography scan of the lungs. CONCLUSIONS: Rendu-Osler disease is a rare cause of stroke due to the fact that it is usually associated with arteriovenous fistulas that can cause paradoxical embolisms. Neurovascular Doppler ultrasound scanning is useful for detecting these pulmonary fistulas by means of the bubble contrast test, which is a non-invasive test that can be carried out easily by neurologists themselves.

Enfermedad de Rendu-Osler-Weber como causa infrecuente de ictus / Rendu-osler-weber disease as an infrequent cause of stroke

La telangiectasia hemorrágica hereditaria o enfermedad de Rendu-Osler es una enfermedad vascularcongénita que se asocia con la presencia de fístulas arteriovenosas que son causa de embolias paradójicas. Caso clínico. Mujer de 83 años que ingresa con clínica de crisis epilépticas y múltiples infartos cerebrales en fase aguda. Asocia historiaprevia de múltiples hemorragias y anemia ferropénica sin clara causa etiológica. Tras una exhaustiva anamnesis, se descubre historia familiar de hemorragias y una hermana diagnosticada de enfermedad de Rendu-Osler-Weber, lo que sugiere la posible existencia de una fístula arteriovenosa pulmonar como causa etiológica de su enfermedad cerebrovascular. Se realiza Doppler neurovascular con infusión de test de burbujas con resultado positivo, lo cual confirma la presencia de la fístula mediante angiotomografía axial computarizada pulmonar. Conclusión. La enfermedad de Rendu-Osler es una causa poco frecuente de ictus debido a que suele asociar fístulas arteriovenosas que pueden ser causa de embolias paradójicas. El Doppler neurovascular es útil para la detección de estas fístulas pulmonares mediante el test de infusión de burbujas; se trata de unaprueba no cruenta y de fácil realización por parte de los propios neurólogos

Análisis de los ingresos evitables en un servicio de neurología / An analysis of avoidable admissions to a neurology service

Introducción. Los ingresos inadecuados a un servicio hospitalariogeneran costes innecesarios a nuestro sistema de salud.La mayoría de ingresos en un servicio hospitalario procede delárea de urgencias. La presencia de un neurólogo que atienda lasurgencias hospitalarias constituiría un factor importante pararacionalizar los criterios de hospitalización. Objetivos. Determinarel número de ingresos evitables (IE) en un servicio de neurologíaasí como definir las características de éstos. Pacientes y métodos.Estudio descriptivo prospectivo de los ingresos realizados enel Servicio de Neurología del Hospital General Universitario deElche (Alicante) durante tres meses. El neurólogo determina laindicación de ingreso. Se recogen los datos de filiación del paciente,el diagnóstico del ingreso, el diagnóstico del neurólogo, el motivode adecuación y el motivo de IE. Resultados. Se atendieron untotal de 250 ingresos; 65 se consideraron IE (26%). Los diagnósticosmás frecuentes de los IE fueron: no neurológico (32,3%), síntomasy signos (15,4%), neuropatías (10,8%) y epilepsia (10,8%).Los motivos de IE fueron: no neurológico y traslado de servicio(30,8%), seguimiento en consultas externas de neurología (CEN)(29,2%), estudio en CEN (21,5%), no neurológico y alta (16,9%) yno consta (1,5%). Los IE tuvieron una estancia media de 4,3 días.Conclusiones. El número de IE en nuestro servicio es más elevadoque en otros estudios. La disponibilidad de guardias de neurología,la agilización de la realización ambulatoria de pruebasdiagnósticas y el diseño de agendas flexibles de asistencia ambulatoriasupondrían una reducción en la utilización de recursos, yaumentaría la calidad del servicio asistencial

Introduction. Inappropriate admissions to a hospital service generate unnecessary costs for our health care service.Most admissions to a hospital service come from the emergency department. The presence of a neurologist to attend hospitalemergencies would be an important factor allowing admission criteria to be streamlined. Aims. To determine the number ofavoidable admissions (AA) in a neurology service, and to define their characteristics. Patients and methods. We conducted aprospective, descriptive study of the admissions that took place in the Neurology Service of the Hospital General Universitariode Elche (Alicante) over a period of three months. The neurologist determines whether admission is indicated or not. Wecollected demographic data concerning the patient, the admission diagnosis, neurological diagnosis, the reason for appropriatenessand the reason for AA. Results. A total of 250 admissions were attended; 65 were considered to be AA (26%). The mostfrequent diagnoses in the cases of AA were non-neurological (32.3%), clinical findings (15.4%), neuropathies (10.8%) andepilepsy (10.8%). The reasons leading to AA were non-neurological and transfer to another service (30.8%), follow-up byneurology outpatient department (NOD) (29.2%), NOD study (21.5%), non-neurological and discharge (16.9%) and notspecified (1.5%). The mean length of stay in the case of AA was 4.3 days. Conclusions. The number of AA in our service ishigher than that found in other studies. On-duty neurologists, streamlining outpatient diagnostic testing and the design offlexible schedules for outpatient care would reduce the amount of resources that are used, while at the same time increasingthe quality of the health service

[A descriptive study of intrahospital consultation to a neurological department]. / Estudio descriptivo de las interconsultas realizadas a un servicio de neurología.

INTRODUCTION: Intrahospital consultation (IC) is a little analyzed activity within daily neurologist hospital care. It entails an extra investment of time and resources. This study aims to describe the number and characteristics of the IC to a neurological department in our setting and to emphasize its importance within daily neurological health care. METHODS: We performed an eighteen-month retrospective study of the requests for consultations received during this period in the Neurology Service of the Hospital General Universitario. The following variables were analyzed: demographic information, number and type of IC, time of response, syndromic diagnosis, complementary tests requested and resolution of patients. RESULTS: 224 IC in 210 patients were seen. The average time of response was 1.57 days, although it was modified because of type of IC (normal: 1.7 days; for preference: 1.5 days; urgent: 0.2 days). The specialities that requested most consultations were cardiology (12.9%) and internal medicine (12.5 %). The most frequent reasons for consultation were: signs and symptoms (27.2%), focal neurological deficit (22.8%) and cognitive impairment (17.9%). CT scan and MRI were the most common complementary tests. A total of 25.4% of patients were referred to neurology outpatient clinic for follow-up. CONCLUSIONS: IC is an infrastudied activity in the literature. We consider it necessary to analyze this kind of care in every hospital in order to improve the organization and the planning of the day-to-day hospital activity

Estudio descriptivo de las interconsultas realizadas a un servicio de neurología / A descriptive study of intrahospital consultation to a neurological department

Introducción. Las interconsultas (IC) son una actividad poco analizada dentro del quehacer diario del neurólogo que desempeña su actividad en el hospital. Supone una inversión «extra» de tiempo y recursos. Nuestro objetivo es el de describir en nuestro medio el número y las características de las IC atendidas y destacar la importancia de las mismas en la labor asistencial diaria del servicio. Métodos. Realizamos un estudio descriptivo retrospectivo de las IC atendidas en el Hospital General durante un período de 18 meses. Se recogieron las variables demográficas, número de IC, tipo de IC, la demora de respuesta y datos de los pacientes referentes a patologías atendidas, pruebas solicitadas y destino de los mismos. Resultados. Se realizaron 224 IC pertenecientes a 210 pacientes. El tiempo medio de respuesta fue de 1,57 días, aunque éste fue variable en función de la urgencia de la solicitud (normal: 1,7 días; preferente: 1,5 días; urgente: 0,2 días). Las especialidades más consultoras fueron cardiología (12,9%) y medicina interna (12,5%). Los motivos de consulta más frecuentes fueron: síntomas y signos (27,2%), focalidad neurológica (22,8 %) y trastorno cognitivo (17,9 %). La prueba más solicitada fue la tomografía computarizada craneal seguida de la resonancia magnética cerebral. Tras la IC, el 25,4% de los pacientes fueron remitidos a consultas externas para seguimiento. Conclusiones. La actividad de las IC es un tema poco tratado en la literatura. Consideramos necesario analizar en cada ámbito este tipo de actividad de modo que se consiga una mejor planificación del trabajo asistencial hospitalario (AU)

[Analysis of the patients who missed their appointments at the neurology clinic of the Marina Alta]. / Análisis de los pacientes no presentados a la consulta de neurología de La Marina Alta.

OBJECTIVES: To analyze the frequency, reasons and characteristics of patients who missed their appointments (NP) at the Neurology Clinic (CEN). To compare the characteristics of the NP with the patients who did not miss their appointment. Suggest measures to reduce avoidable causes of NP. PATIENTS AND METHODS: During the period 1/10/99 to 30/4/2000 the cases of NP were prospectively recorded and compared with a sample of patients who attended the CEN during the same period. We analyze the data on age, sex, distance of home from CEN, diagnosis, type of consultation and date of last consultation. The NP were contacted by phone and asked why they had not gone for their appointments. The reasons given were then classified as avoidable or unavoidable. RESULTS: Of the 1,842 consultations scheduled, 19% were NP. When the NP and the patients who did attend were compared we found statistically significant differences regarding the distance home/CEN. According to the diagnosis, the NP had more 'symptoms/signs' and other MIA, whilst those who attended the clinic had more 'neuropathies' and 'awaiting diagnosis'. The commonest avoidable reasons (55.8%) for NP were forgetting, administrative error and communication failure, and for unavoidable reasons (44.2%) physical disability, other priorities and improvement. CONCLUSIONS: There is a large proportion of NP in the CEN of the Marina Alta. The distance from home to CEN (over 25 km) was the main factor affecting the rate of NP. Since 56% of the NP were due to avoidable causes, strategies could be designed to reduce this percentage. In the NP group, the main causes were forgetting, administrative errors and communication failure.

Análisis de los pacientes no presentados a la consulta de neurología de la Marina Alta / Analysis of the patients who missed their appointments at the neurology clinic of the Marina Alta

Objetivos. Analizar la frecuencia, motivos y características de los pacientes que no se presentaron (NP) a su cita en la consulta de Neurología (CEN). Comparar las características de los NP con relación a los presentados. Proponer intervenciones para minimizar los NP por motivos evitables. Pacientes y métodos. Durante el período comprendido entre el 1/10/1999 y el 30/4/2000 se registraron prospectivamente los casos de NP y se compararon con una muestra de los pacientes que sí acudieron a la CEN en ese mismo período. Analizamos los datos correspondientes a edad y sexo, distancia domicilio/CEN, diagnóstico, tipo de visita, fecha de la última visita. A los NP se les entrevistó telefónicamente y, tras solicitarles el motivo de su ausencia, se clasificaron en evitables y no evitables. Resultados. De las 1.842 visitas previstas el 19 por ciento se clasificó como NP. Al comparar NP y presentados se encontraron diferencias estadísticamente significativas (DES) en lo referente a la distancia domiclio/CEN. Según diagnóstico, los NP tenían más `síntomas/signos' y `otros MIA'; los presentados, más `neuropatías' y `pendientes de diagnóstico'. Los motivos más frecuentes de NP se clasificaron así: evitables (55,8 por ciento): olvido, error administrativo y fallos de comunicación; no evitables (44, por ciento): incapacidad física, otras prioridades y mejoría. Conclusiones. Existe una importante proporción de NP en la CEN del área de Marina Alta. La distancia domicilio/CEN (superior a 25 km) es el principal factor que influye en la tasa de NP. El 56 por ciento de los NP lo fueron por motivos evitables, por lo que se podrían diseñar intervenciones para disminuir su número. Dentro de este grupo los principales motivos son los olvidos, los errores administrativos y los fallos en la comunicación (AU)
