Development and validation of a prognostic index (BODEXS90) for mortality in stable chronic obstructive pulmonary disease.

INTRODUCTION: Several multidimensional indices have been proposed to predict mortality in chronic obstructive pulmonary disease (COPD). The BODEX index is simple and easy to use for this purpose in all clinical settings. Only a few prognostic indices have integrated oxygenation variables, with measurement methods that are not practical for real life clinical practice in all settings. OBJECTIVES: To develop and externally validate a new prognostic index (BODEXS90) that combines the variables included in BODEX index with rest peripheral oxygen saturation measured with finger oximetry (SpO2) to predict all-cause mortality in stable COPD. METHOD: Observational, non-intervention, multicenter historic cohort study. The BODEXS90 index was developed in a derivation cohort and externally validated in a validation cohort. Calibration of the index was carried out using Hosmer-Lemeshow test. The discrimination capacity of BODEXS90 and BODEX were compared by means of receiver-operating characteristics curves. Modelling of the index was carried out by crude and adjusted Cox regression analysis. RESULTS: The derivation and validation cohorts included 787 and 1179 subjects, respectively. SpO2 predicted all cause-mortality independently of BODEX index. Discrimination capacity of BODEXS90 to predict the outcome was significantly higher than that of BODEX, particularly for more severely affected patients, both in the derivation and in the validation cohorts. CONCLUSIONS: The new index is potentially useful for designing clinical decision-making algorithms in stable COPD.

Discordancia del tratamiento de la enfermedad pulmonar obstructiva crónica según la guía GesEPOC vs. GOLD / Discordance in treatment of chronic obstructive pulmonary disease following GesEPOC Guideline vs. GOLD

Introducción En España, el tratamiento farmacológico de la enfermedad pulmonar obstructiva crónica se basa en la Global Initiative for Chronic Obstructive Lung Disease (GOLD) y la Guía española de la enfermedad pulmonar obstructiva crónica (GesEPOC). El objetivo principal de este estudio fue evaluar la concordancia entre los tratamientos de inicio asignados por GOLD y GesEPOC. Material y métodos Estudio de simulación. Se emplearon las siguientes variables: FEV1%, exacerbaciones, disnea inicial, eosinofilia en sangre, antecedente de asma y grado de reversibilidad en la prueba broncodilatadora. Cuatro neumólogos clasificaron/asignaron un tratamiento a cada paciente (2 de ellos según GOLD y 2 según GesEPOC). Se calculó el coeficiente Kappa de Cohen global. Resultados Se incluyeron 467 pacientes. La concordancia entre el tratamiento recomendado por GOLD y GesEPOC fue pobre (Kappa: 0,17, IC 95%: 0,12-0,23). Conclusión Existe una pobre concordancia entre GOLD y GesEPOC a la hora de iniciar tratamiento en los pacientes con enfermedad pulmonar obstructiva crónica (AU)

Introduction Pharmacological treatment of chronic obstructive pulmonary disease in Spain is usually chosen according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) or Spanish guidelines for chronic obstructive pulmonary disease (GesEPOC). The main objective of this study was to evaluate the degree of concordance between treatment for newly diagnosed chronic obstructive pulmonary disease patients according to GOLD and GesEPOC. Material and methods Simulation study. The following variables were used: FEV1%, exacerbations, dyspnoea at first evaluation, blood eosinophilia, personal history of asthma, and degree of bronchodilator reversibility. Four investigators classified and assigned a treatment to each patient (2 using GOLD criteria and the other 2 using GesEPOC). Global Kappa index was calculated. Results The database included 467 patients. Agreement between treatment decided using GOLD and GesEPOC was poor (Kappa: 0.17, 95% CI: 0.12-0.23). Conclusion There is a poor agreement between GOLD and GesEPOC recommendations for initial chronic obstructive pulmonary disease treatment (AU)
