El Cuestionario de Salud SF-36 español: una década de experiencia y nuevos desarrollos

Objetivo: El Cuestionario SF-36 es uno de los instrumentos de Calidad de Vida Relacionada con la Salud (CVRS) mas utilizados y evaluados. Tras una decada de uso este articulo revisa criticamente el contenido, propiedades metricas y nuevos desarrollos de la version espanola. Metodos: Revision de los articulos indizados en Medline (PubMed) y en las bases de datos IBECS e IME que han utilizado la version espanola del cuestionario. Se seleccionaron los articulos con informacion sobre modelo de medida, fiabilidad, validez y sensibilidad al cambio del instrumento. Resultados: Se encontraron 79 articulos, 17 de los cuales describian caracteristicas metricas del cuestionario. En el 96% las escalas superaron el estandar propuesto de fiabilidad (α de Cronbach) de 0,7. Las estimaciones agrupadas obtenidas por metaanalisis fueron superiores a 0,7 en todos los casos. El SF-36 mostro buena discriminacion entre grupos de gravedad, correlacion moderada con indicadores clinicos y alta con otros instrumentos de CVRS. El SF-36 predijo mortalidad y detecto mejoria tras la angioplastia coronaria, la cirugia de hipertrofia prostatica benigna o la ventilacion domiciliaria no invasiva. Los nuevos desarrollos descritos (puntuaciones basadas en normas, la version 2, el SF-12 y el SF-8) mejoraron sus propiedades metricas y su interpretacion. Conclusiones: El SF-36, conjuntamente con las nuevas versiones desarrolladas, es un instrumento muy adecuado para su uso en investigacion y en la practica clinica.

The epidemiology of eating disorders in six European countries: Results of the ESEMeD-WMH project

Few data are available to estimate the prevalence of eating disorders (EDs) and their correlates in the community. This paper reports data on EDs obtained in the framework of the ESEMeD project, aimed at investigating the prevalence of non-psychotic mental disorders in six European countries (Belgium, France, Germany, Italy, the Netherlands and Spain), using a new version of the Composite International Diagnostic Interview. The ESEMeD study was a general population cross-sectional household survey. In total, 21,425 respondents aged 18 or older provided data for the project between January 2001 and August 2003. A subsample (N=4139) underwent a detailed investigation on EDs. Lifetime estimated prevalence of anorexia nervosa, bulimia nervosa, binge eating disorder, sub-threshold binge eating disorder, and any binge eating were 0.48%, 0.51%, 1.12%, 0.72%, and 2.15%, respectively, and they were 3-8 times higher among women for all EDs. However, since people under 18 were excluded from this study, our prevalence should be taken as lower-bound estimate of real frequencies. Indeed, cumulative lifetime prevalence analysis showed that the majority of eating disorders had their initial onset between 10 and 20 years of age. Role impairment and comorbidity with other mental disorders were highly common, yet only small proportions of patients with a lifetime diagnosis of EDs requested medical treatment. It still has to be proven whether early diagnostic identification and access to specialized care can reduce the burden caused by these disorders.

Prevalencia de los trastornos mentales y factores asociados: resultados del estudio ESEMeD-España

Fundamento y objetivo El proyecto ESEMeD-Espana es un estudio epidemiologico sobre los trastornos mentales en nuestro pais. Se presentan la prevalencia-ano y prevalencia-vida de los principales trastornos del estado de animo, de ansiedad y de abuso de alcohol, asi como la influencia de los factores de riesgo sociodemograficos en su presencia y la edad de inicio de los trastornos. Sujetos y metodo Encuesta personal domiciliaria realizada a una muestra representativa de la poblacion espanola mayor de 18 anos de 5.473 individuos. El instrumento utilizado fue la version del Composite International Diagnostic Interview (WMH-CIDI) desarrollada para la iniciativa Encuestas de Salud Mental de la Organizacion Mundial de la Salud (WHO World Mental Health Surveys). La tasa de respuesta fue del 78,6%. Los resultados se presentan ponderados a la poblacion espanola. Resultados Un 19,5% de las personas presentaron un trastorno mental en algun momento de su vida (prevalencia-vida) y un 8,4% en los ultimos 12 meses (prevalencia-ano). El trastorno mental mas frecuente es el episodio depresivo mayor, que tiene un 3,9% de prevalencia-ano y un 10,5% de prevalencia-vida. Despues del episodio depresivo mayor, los trastornos con mayor prevalencia-vida son la fobia especifica, el trastorno por abuso de alcohol y la distimia. Los factores asociados a padecer un trastorno mental son el sexo femenino, estar separado, divorciado o viudo, y estar desempleado, de baja laboral o con una incapacidad. La fobia social, la agorafobia y la fobia especifica aparecen a edades mas tempranas. Los trastornos del estado de animo (episodio de depresion mayor y distimia), junto con el trastorno de angustia, muestran una aparicion mas tardia. Conclusiones El estudio ESEMeD-Espana puede proporcionar resultados necesarios para conocer el impacto de los trastornos mentales en Espana.

12-Month comorbidity patterns and associated factors in Europe: results from the European Study of the Epidemiology of Mental Disorders (ESEMeD) project

Objective:  Comorbidity patterns of 12‐month mood, anxiety and alcohol disorders and socio‐demographic factors associated with comorbidity were studied among the general population of six European countries.

Home hospitalisation of exacerbated chronic obstructive pulmonary disease patients

It was postulated that home hospitalisation (HH) of selected chronic obstructive pulmonary disease (COPD) exacerbations admitted at the emergency room (ER) could facilitate a better outcome than conventional hospitalisation. To this end, 222 COPD patients (3.2% female; 71±10 yrs (mean±sd)) were randomly assigned to HH (n=121) or conventional care (n=101). During HH, integrated care was delivered by a specialised nurse with the patients free-phone access to the nurse ensured for an 8‐week follow-up period. Mortality (HH: 4.1%; controls: 6.9%) and hospital readmissions (HH: 0.24±0.57; controls: 0.38±0.70) were similar in both groups. However, at the end of the follow-up period, HH patients showed: 1) a lower rate of ER visits (0.13±0.43 versus 0.31±0.62); and 2) a noticeable improvement of quality of life (Δ St Georges Respiratory Questionnaire (SGRQ), −6.9 versus −2.4). Furthermore, a higher percentage of patients had a better knowledge of the disease (58% versus 27%), a better self-management of their condition (81% versus 48%), and the patients satisfaction was greater. The average overall direct cost per HH patient was 62% of the costs of conventional care, essentially due to fewer days of inpatient hospitalisation (1.7±2.3 versus 4.2±4.1 days). A comprehensive home care intervention in selected chronic obstructive pulmonary disease exacerbations appears as cost effective. The home hospitalisation intervention generates better outcomes at lower costs than conventional care.

Validation of the "World Health Organization Disability Assessment Schedule, WHODAS-2" in patients with chronic diseases

BackgroundThe WHODAS-2 is a disability assessment instrument based on the conceptual framework of the International Classification of Functioning, Disability, and Health (ICF). It provides a global measure of disability and 7 domain-specific scores. The aim of this study was to assess WHODAS-2 conceptual model and metric properties in a set of chronic and prevalent clinical conditions accounting for a wide scope of disability in Europe.Methods1,119 patients with one of 13 chronic conditions were recruited in 7 European centres. Participants were clinically evaluated and administered the WHODAS-2 and the SF-36 at baseline, 6 weeks and 3 months of follow-up. The latent structure was explored and confirmed by factor analysis (FA). Reliability was assessed in terms of internal consistency (Cronbachs alpha) and reproducibility (intra-class correlation coefficients, ICC). Construct validity was evaluated by correlating the WHODAS-2 and SF-36 domains, and comparing known groups based on the clinical-severity and work status. Effect size (ES) coefficient was used to assess responsiveness. To assess reproducibility and responsiveness, subsamples of stable (at 6 weeks) and improved (after 3 moths) patients were defined, respectively, according to changes in their clinical-severity.ResultsThe satisfactory FA goodness of fit indexes confirmed a second order factor structure with 7 dimensions, and a global score for the WHODAS-2. Cronbachs alpha ranged from 0.77 (self care) to 0.98 (life activities: work or school), and the ICC was lower, but achieved the recommended standard of 0.7 for four domains. Correlations between global WHODAS-2 score and the different domains of the SF-36 ranged from -0.29 to -0.65. Most of the WHODAS-2 scores showed statistically significant differences among clinical-severity groups for all pathologies, and between working patients and those not working due to ill health (p < 0.001). Among the subsample of patients who had improved, responsiveness coefficients were small to moderate (ES = 0.3-0.7), but higher than those of the SF-36.ConclusionsThe latent structure originally designed by WHODAS-2 developers has been confirmed for the first time, and it has shown good metric properties in clinic and rehabilitation samples. Therefore, considerable support is provided to the WHODAS-2 utilization as an international instrument to measure disability based on the ICF model.
