[Patient safety: Patients perception at primary care level at an urban healthcare district]. / Seguridad del paciente: percepción de los pacientes en atención primaria de un distrito sanitario urbano.

OBJECTIVES: Patient safety is a quality objective and a priority in healthcare. Most of the research has focused on the hospital setting and from the professional perspective. The objective of our study is to know the opinion of the patient who attends primary care regarding its safety in this area. MATERIAL AND METHODS: Cross-sectional observational study. A survey carried out with patients chosen through four health centres representing different socioeconomic levels of the same Basic Health Zone. Fifty patients per centre were surveyed. RESULTS: Two hundred patients surveyed of whom more than 90% reported no negative experiences in terms of errors in medication, identification, diagnosis or clinical management, highlighting the good care received and the good resolution of their problem. However, only around half claimed to understand the explanations of the healthcare professionals or to have had the opportunity to give an opinion or have shared decision-making on their management. These factors were closely related to the perceived lack of time in consultation and constant change of physician. CONCLUSIONS: The vast majority of our patients report no adverse effects or safety issues during their primary care attendance. However, there is evidence of the need to strengthen aspects related to consultation time and increase the number and stability of human resources in health centres to improve patient satisfaction with the health system.

[International visibility and impact of the Spanish research on prison health (2002-2011)]. / Visibilidad internacional e impacto de la producción científica española en Sanidad Penitenciaria (2002-2011).

OBJECTIVE: This paper sets out to analyze the dissemination and impact of Spanish research published in international scientific journals on Prison Health over the last decade. MATERIAL AND METHODS: Descriptive, longitudinal and retrospective analysis of scientific output. We used the Medline-Pubmed database as an information resource. We focus on the bibliometric aspects of journals, papers and authors using the indicators offered by the Web of Science, the Journal Citation Reports and the Essential Science Indicators. We identify the output of Spanish researchers, journals in which they are published, authors and main research fields. RESULTS: From 2002 to 2011, Spanish researchers published 159 papers, that is, nearly 2% of the world's share in Prison Health. The publication profile is mainly in international journals with an average impact on JCR. The Revista Española de Sanidad Penitenciaria is the most productive journal (9.09%), although its role is not prominent. Only two authors can be considered as medium-high productive authors with 10 papers in the study time period. The co-authors network shows a dense network with 14 authors along with minor fragmented networks. As regards citations, 6 papers have been cited 15 or more times and only two can be considered as highly cited. Three main research fronts have been identified: infectious diseases, drugs and psychiatric-psychological problems. CONCLUSIONS: The Spanish research production on Prison Health represents a similar share of the world output similar to that of other disciplines (1.9%), although slightly lower (General Medicine represents 3.05%; Public Health, 2.38%; Psychiatry, 2.29%; Toxicology, 2.46%). It seems likely that this share will increase as a result of the inclusion of its main journal in Medline along with an increasing number of researchers working on this discipline at an international level. However, inclusion has not yet led to integration into high-impact journals or a larger number of citations. The average Journal Impact Factor is relatively low (2.062) and few papers are published in first-class journals (Q1). There are few articles with a good citation average according to the discipline's standard. Likewise, the collaboration pattern still shows a poor state for Spanish research on Prison Health.

Visibilidad internacional e impacto de la producción científica española en Sanidad Penitenciaria (2002-2011) / International visibility and impact of the Spanish research on Prison Health (2002-2011)

Objetivo: Analizar la difusión y el impacto de la investigación española sobre Sanidad Penitenciaria en los últimos diez años publicada en revistas científicas internacionales Material y método: Estudio descriptivo, longitudinal y retrospectivo de la producción científica. Se ha utilizado como fuente de información Medline-Pubmed. Se analizan aspectos bibliométricos de las revistas, los trabajos y los autores utilizando indicadores de Web of Science, Journal Citation Reports y los Essential Indicator. Se identifica la producción, las revistas, los autores y los temas de investigación Resultados: Son 159 los trabajos publicados, lo que supone casi el 2% de la producción mundial en sanidad penitenciaria. El perfil de publicación mayoritario es en revistas internacionales de medio impacto en los JCR. La Revista Española de Sanidad Penitenciaria, sin alcanzar protagonismo, es la más productiva (9.09%). Por autores, solo dos alcanzan un nivel medio alto con hasta 10 trabajos publicados en la década. El estudio de coautoría muestra una red muy tupida con 14 autores y distintas redes menores fragmentadas. Respecto de las citas, 6 son los trabajos que reciben 15 o más, siendo solo 2 los que podemos considerar altamente citados. Los temas de estudio presentan tres frentes: enfermedades infecciosas, drogas y problemas psiquiátricopsicológicos Conclusiones: La aportación española a la investigación mundial en Sanidad Penitenciaria (1,9%) está próxima a otras disciplinas, aunque es ligeramente inferior (Medicina General representa el 3,05%, Salud Pública 2,38%, Psiquiatría 2,29%, Toxicología 2,46%). Se prevé que la Sanidad Penitenciaria remontará con la incorporación a Medline de su revista homónima y con el colectivo de autores que se ha incorporado a la corriente internacional. Esta incorporación no ha significado aun la integración en revistas de alto nivel y en citación. Las revistas utilizadas promedian un Factor de Impacto bajo (2,062) y son escasos los trabajos en revistas de primer nivel (Q1). Son pocos los trabajos con un promedio aceptable de citas en su área de conocimiento. El patrón de coautoría muestra aún un estado inmaduro de la investigación española en Sanidad Penitenciaria(AU)

[Analgesia for childbirth in a patient with factor V Leiden mutation]. / Analgesia para trabajo de parto en paciente con mutación del factor V Leiden.

Factor V Leiden mutation is the most common congenital thrombophilic disorder, affecting between 5% and 8% of the Caucasian population. Pregnancy creates a state of hypercoagulability and all factors that increase the risk of thrombosis should be considered, as they may be cumulative. In recent years, the diagnosis of new allelic variants of thrombophilic states have increased the incidence of pregnant women receiving anticoagulant therapy, with the anesthetic considerations that implies. We report the case of a 33-year-old woman with heterozygous Leiden factor V mutation who was admitted with spontaneous amniorrhexis in the 38th week of gestation. She was taking low molecular weight heparin therapy. An epidural catheter was inserted to provide analgesia for labor, with all safety precautions to prevent an epidural hematoma. Epidural anesthesia is the technique of choice for obstetric labor in patients with hypercoagulability because of its effects of favoring blood flow and inhibiting clot formation.

Analgesia para trabajo de parto en paciente con mutación del factor V Leiden / Analgesia for childbirth in a patient with Factor V Leiden mutation

La mutación del factor V Leiden, es la forma más frecuente de trastorno trombofílico congénito, afectando al 5-8% de la población caucasiana. La gestación supone, en sí misma, un estado de hipercoagulabilidad que nos debe llevar a prestar especial atención a todos aquellos factores de riesgo trombótico que puedan sumarse. En los últimos años, el diagnóstico de las nuevas variantes alélicas de los estados trombofílicos, ha incrementado la incidencia de gestantes que reciben anticoagulación con las consideraciones anestésicas que ello conlleva. Presentamos el caso de una mujer de 33 años de edad, portadora heterocigoto de una mutación en el gen del factor V Leiden, en tratamiento con heparina de bajo peso molecular, que ingresa por amniorrexis espontánea a la semana 38 de gestación. La paciente requirió analgesia para el trabajo de parto, por lo que se le colocó un catéter epidural cumpliendo los protocolos de seguridad y prevención del hematoma epidural. La anestesia epidural es la técnica de elección para analgesia del trabajo de parto, en las pacientes con hipercoagulabilidad, por sus efectos sobre la reología vascular y su efecto antitrombótico

[Anesthesia for carbon dioxide laser surgery to correct Zenker's diverticulum]. / Anestesia para la cirugía del divertículo de Zenker con láser CO2.

Two 48- and 62-year-old men, the latter with a history of ischemic heart disease, underwent endoscopic carbon dioxide laser surgery to correct Zenker's diverticulum. We provided total intravenous anesthesia, taking into consideration the special requirements of laser surgery. The pathogenesis of Zenker's diverticulum, the most common type of esophageal diverticulum, is poorly understood and the treatment approach depends on size and overall patient status. Patients with Zenker's diverticulum need a thorough preoperative assessment with special attention to airway permeability and the degree of difficulty of intubation. Anesthesia should be maintained in a manner that provides the safest, most effective surgical conditions.

Anestesia para la cirugía del divertículo de Zenker con láser CO2 / Anesthesia for carbon dioxide laser surgery to correct Zenker's diverticulum

Dos varones de 48 y 62 años de edad, el mayor con antecedentes de cardiopatía isquémica, fueron intervenidos de divertículo de Zenker por vía endoscópica con láser CO2. La técnica anestésica empleada fue una total intravenosa, con todas las consideraciones que la cirugía láser requiere. El divertículo esofágico más frecuente es el de Zenker, de etiopatogenia controvertida y cuyo tratamiento dependerá de su tamaño y del estado general del paciente. Estos enfermos necesitan una valoración preoperatoria exhaustiva, con especial atención a la permeabilidad de la vía aérea y al grado de dificultad de intubación. El mantenimiento anestésico de estos pacientes persigue que puedan ser intervenidos bajo las condiciones máximas de seguridad y eficacia (AU)

Gabapentina y dolor crónico postlaminectomía / Gabapentin and postlaminectomy chronic pain

Introducción: El dolor crónico postlaminectomía, también denominado síndrome de cirugía fallida de espalda, es una complicación grave y relativamente frecuente de la cirugía de la columna vertebral. En algunos casos, la clínica puede llegar a ser más discapacitante que el cuadro inicial que llevó al paciente a la intervención quirúrgica. Es un problema clínico difícil de tratar y para el que encontramos pocos tratamientos efectivos. La gabapentina se ha mostrado útil en el tratamiento de numerosos estados dolorosos neuropáticos pero, hasta la fecha, no existen estudios a largo plazo sobre su utilización en el dolor postlaminectomía. Material y métodos: Se realiza un estudio prospectivo sobre 63 pacientes consecutivos que acuden a la Unidad del Dolor por dolor postlaminectomía. Las dosis de gabapentina se iniciaron con 300 mg en dosis única nocturna, aumentando 300 mg cada 7 días hasta alcanzar dosis diarias de 1.200 mg (en tomas repartidas cada 8 horas). En función de la respuesta, la dosis se fue aumentando paulatinamente hasta un máximo de 2.400 mg.día-1. Al mes, a los 3 meses y a los 6 meses se valoraron las variaciones de puntuación de la Escala Visual Analógica (EVA) y del test de Lattinen. Resultados: De los 63 pacientes que iniciaron el estudio, el 42 por ciento eran varones y el 58 por ciento mujeres, con una edad media de 55 ñ 9,98 años. No finalizaron el estudio 3 pacientes (4,9 por ciento), uno por somnolencia excesiva, otro por olvidos (trastorno cognitivo) y otro por pérdida de seguimiento. La valoración de la EVA nos muestra una disminución estadísticamente significativa de 7 inicial, a 2 al sexto mes (p<0,01). Ya en el primer mes encontramos una disminución estadísticamente significativa (7 a 5), al igual que a los 3 meses (7 a 3). En las puntuaciones del test de Lattinen también existe una disminución progresiva y estadísticamente significativa ya desde el primer mes de tratamiento. Las dosis medias de gabapentina fueron inicialmente de 300 mg.día-1; al mes, 1.100 mg.día-1; a los 3 meses 1.400 mg.día-1a y a los 6 meses de 1.250 mg.día-1. Como efectos secundarios, durante el primer mes el 20 por ciento de los pacientes refirieron somnolencia; el 15 por ciento, astenia; el 10 por ciento inestabilidad; y, ansiedad, molestias gastrointestinales y olvidos, en un 5 por ciento respectivamente. Sólo en dos pacientes se interrumpió el estudio por los efectos secundarios (el tercer paciente retirado fue perdido del seguimiento), siendo los efectos secundarios en el resto de los casos transitorios, mejorando con el transcurso de los días tras el inicio de la medicación. Conclusión: La gabapentina es un fármaco eficaz para el manejo del dolor postlaminectomía, con una incidencia de efectos secundarios aceptable y de escasa intensidad, que desaparecen en pocas semanas con la continuación del tratamiento. Se necesitan más estudios a largo plazo sobre su uso y es necesaria su valoración frente a otros fármacos así como frente a placebo. Sin embargo, ante estos resultados iniciales, consideramos que la gabapentina puede ser un fármaco de elección preferente en el control de este cuadro doloroso (AU)

Spanish personal name variations in national and international biomedical databases: implications for information retrieval and bibliometric studies.

OBJECTIVES: The study sought to investigate how Spanish names are handled by national and international databases and to identify mistakes that can undermine the usefulness of these databases for locating and retrieving works by Spanish authors. METHODS: The authors sampled 172 articles published by authors from the University of Granada Medical School between 1987 and 1996 and analyzed the variations in how each of their names was indexed in Science Citation Index (SCI), MEDLINE, and Indice Medico Español (IME). The number and types of variants that appeared for each author's name were recorded and compared across databases to identify inconsistencies in indexing practices. We analyzed the relationship between variability (number of variants of an author's name) and productivity (number of items the name was associated with as an author), the consequences for retrieval of information, and the most frequent indexing structures used for Spanish names. RESULTS: The proportion of authors who appeared under more then one name was 48.1% in SCI, 50.7% in MEDLINE, and 69.0% in IME. Productivity correlated directly with variability: more than 50% of the authors listed on five to ten items appeared under more than one name in any given database, and close to 100% of the authors listed on more than ten items appeared under two or more variants. Productivity correlated inversely with retrievability: as the number of variants for a name increased, the number of items retrieved under each variant decreased. For the most highly productive authors, the number of items retrieved under each variant tended toward one. The most frequent indexing methods varied between databases. In MEDLINE and IME, names were indexed correctly as "first surname second surname, first name initial middle name initial" (if present) in 41.7% and 49.5% of the records, respectively. However, in SCI, the most frequent method was "first surname, first name initial second name initial" (48.0% of the records) and first surname and second surname run together, first name initial (18.3%). CONCLUSIONS: Retrievability on the basis of author's name was poor in all three databases. Each database uses accurate indexing methods, but these methods fail to result in consistency or coherence for specific entries. The likely causes of inconsistency are: (1) use by authors of variants of their names during their publication careers, (2) lack of authority control in all three databases, (3) the use of an inappropriate indexing method for Spanish names in SCI, (4) authors' inconsistent behaviors, and (5) possible editorial interventions by some journals. We offer some suggestions as to how to avert the proliferation of author name variants in the databases.

[Prevalence of tuberculosis infection in the school age in Guadalajara, Spain]. / Prevalencia de la infección tuberculosa en el medio escolar de Guadalajara.

OBJECTIVES: To estimate the prevalence of tuberculosis infected children in the first grades of Primary Education and to analyse the distribution of infected people among social class groups and other previous circumstances. METHODS: Cross-sectional study with diagnostic test application and questionnaire survey, in a representative sample of the school population of the province of Guadalajara, Spain (two stages sampling design). Tuberculin skin tests with 2 I.U. of P.P.D. RT-23 and the Sokal method for lecture were used. For occupational classification and social class definition were used the criteria of the last report of Spanish Epidemiology Society. RESULTS: A total of 1,093 children (50.8% males) between 6 and 9-year-old were studied. The overall prevalence of infected children was 1.64 (I.C.:1-2.3). The distribution of infection did not show significant differences between urban/rural population, previous disease, family antecedent, social class, dwelling area and occupational activities of parents. The prevalence increased in the older upper school years and among the older children. Prevalence ranged from 0.4% (CI: 0.01-1.3) in the first year to 3.53% (CI: 2.4-4.6) in the last year. Children born in 1988 had a 3.23% prevalence (CI: 1.2-5,1), while those born in 1989; 1990 and 1991 had a prevalence of 0.73 (CI: 0-1.77), 1.88% (CI: 0.2-3.51) and 0.4% (0-1.2), respectively. CONCLUSIONS: Tuberculosis infection is less prevalent at school ages than other areas of Spain. In spite of the increase prevalence per school year, the low frequency and sample size did not allow to test for other associations.

Prevalencia de la infección tuberculosa en el medio escolar de Guadalajara / Prevalence of tuberculosis infection in the school age in Guadalajara, Spain

Objetivos: Estimar la prevalencia de infección tuberculosa en los niños escolarizados en los cuatro primeros cursos de Educación Primaria, y analizar su distribución según su clase social y la existencia de antecedentes de enfermedad. Métodos: Se trata de un estudio transversal mediante la aplicación de prueba diagnóstica y autocumplimentación de encuesta en una muestra representativa de la población escolar de la provincia de Guadalajara en 1997-1998 (diseño muestral polietápico). Se aplicó la prueba de la tuberculina utilizando 2 UT del lote PPD-RT 23, según normas de consenso y lectura por el método de Sokal. La clasificación de ocupaciones y la definición de clase social se hizo según la actualización de la Sociedad Española de Epidemiología. Resultados: Se estudiaron 1.093 niños (50,8 por ciento varones) comprendidos entre 6 y 9 años de edad. La prevalencia total de infectados fue de 1,64 por ciento (IC: 1-2,3). La distribución de infectados no mostró diferencias significativas para el estrato urbano-rural, antecedentes familiares, clase social, superficie de la vivienda y tipo de actividad ocupacional desarrollada por los padres. La prevalencia aumentó en los cursos superiores y en los niños de mayor edad, siendo de 0,4 por ciento (IC: 0,01-1,3) en el primer curso y de 3,53 por ciento (IC:2,4-4,6) en el último. En los nacidos en 1988 la prevalencia fue de 3,23 (IC: 1,2-5,1), y de 0,73 (IC: 0-1,7), 1,88 (IC: 0,2-3,51), y 0,4 (IC: 0-1,2) en los nacidos en 1989, 1990 y 1991, respectivamente. Conclusiones: La infección tuberculosa es poco prevalente en nuestro medio escolar en relación a estudios de otras comunidades. Esta baja frecuencia y el tamaño muestral utilizado han impedido la estimación estadística de posibles diferencias en la distribución de infectados en algunos subgrupos estudiados, aunque se puede objetivar una mayor afectación en los más mayores (AU)

Editorial quality, diffusion and bibliometric indicators of the Revista Espaãnola de Enfermedades Digestivas.

AIM: To evaluate the editorial quality, diffusion, relevance of the scientific content, and the publication practices of the specialised journal Revista Española de Enfermedades Digestivas. MATERIALS AND METHODS: We checked 136 parameters based on ISO standards, the recommendations of scientific and editorial organisations, and studies of scientific editing and international publishing practices for biomedical journals. Diffusion was calculated using national and international databases, specialised libraries in Spain, and Internet sources. The analysis of the scientific content and publication practices was based on bibliometric indicators for the journal, authorship, and contributions. The sample for this study comprised six alternate issues of volume number 88 (1996), the last issue of this volume, and the first issue of volume 89 (1997). The samples used for the bibliometric analysis varied depending on the characteristics of specific indicators and the availability of information. RESULTS: The overall mean value for compliance with standards was 46.1%, while the real mean was calculated at 72.21%. The editorial procedures at the journal are similar to those of analogous international journals. The Revista Española de Enfermedades Digestivas is included in international databases of biomedical journals, and in the interdisciplinary international database SCI. It was found to be present in 70% of the medical libraries of Spanish universities, and in 73% of the hospital libraries studied. Bibliometric indicators showed co-authorship to be 5.5%; the origin of the authors grouped by province and by type of institutional affiliations showed 27.8% of all authors to be from Madrid, and that more were affiliated with general hospitals than with university hospitals. The mean delay between initial receipt of a manuscript and its publication was 300 days. Cocitation analysis gave the journal a central position amongst the 38 Spanish biomedical journals considered representative of the field. The journal's impact factor for 1996 was 0.260. CONCLUSIONS: The Revista Española de Enfermedades Digestivas is a high-quality vehicle of research results, and has acceptable internal editorial procedures. The journal is widely distributed, though its visibility on the Internet should be improved. Co-authorship is similar to that seen in other medical journals. Steps should be taken to make this journal better known within Spain, and to reduce the delay between the initial receipt and the final publication of manuscripts. Its impact factor is increasing steadily.
