Article excerpt

Objective To create patient-based disability weights for individual injury diagnosis codes and nature-of-injury classifications, for use, as an alternative to panel-based weights, in studies on the burden of disease.

Methods Self-reported data based on the EQ-5D standardized measure of health status were collected from 29 770 participants in the Injury-VIBES injury cohort study, which covered Australia, the Netherlands, New Zealand, the United Kingdom of Great Britain and Northern Ireland and the United States of America. The data were combined to calculate new disability weights for each common injury classification and for each type of diagnosis covered by the 10th revision of the International statistical classification of diseases and related health problems. Weights were calculated separately for hospital admissions and presentations confined to emergency departments.

Findings There were 29 770 injury cases with at least one EQ-5D score. The mean age of the participants providing data was 51 years. Most participants were male and almost a third had road traffic injuries. The new disability weights were higher for admitted cases than for cases confined to emergency departments and higher than the corresponding weights used by the Global Burden of Disease 2013 study. Long-term disability was common in most categories of injuries.

Conclusion Injury is often a chronic disorder and burden of disease estimates should reflect this. Application of the new weights to burden studies would substantially increase estimates of disability-adjusted life-years and provide a more accurate reflection of the impact of injuries on peoples' lives.

Objectif Elaborer de nouveaux coefficients de ponderation de l'incapacite, fondes sur des declarations de patients, pour les differents codes diagnostiques des traumatismes corporels et pour les differentes natures de traumatismes, en vue de les utiliser comme alternative aux ponderations fondees sur des panels dans les etudes sur les charges de morbidite.

Methodes Des auto-declarations ont ete recueillies grace au questionnaire standardise EQ-5D d'evaluation de l'etat de sante aupres de 29 770 participants-de l'etude <> qui a ete menee sur une cohorte de blesses en Australie, aux Etats-Unis d'Amerique, en Nouvelle-Zelande, aux Pays-Bas et au Royaume-Uni de Grande-Bretagne et d'Irlande du Nord. Ces donnees ont ete combinees pour calculer de nouveaux coefficients de ponderation de l'incapacite pour chaque principale categorie de traumatisme et pour chaque type de diagnostic couvert par la 10eme revision de la Classification statistique internationale des maladies et des problemes de sante connexes. Les coefficients de ponderation ont ete calcules separement pour les patients hospitalises et les patients uniquement pris en charge par les services d'urgence.

Resultats Il y a eu 29 770 cas de traumatismes pour lesquels au moins un score EQ-5D a ete obtenu. L'age moyen des participants ayant communique des donnees est de 51 ans. Pour la plupart, les participants etaient des hommes et pres d'un tiers, des accidentes de la route. Les nouveaux coefficients de ponderation sont superieurs pour les participants hospitalises comparativement aux patients uniquement pris en charge par des services d'urgence et superieurs aux coefficients de ponderation correspondants utilises dans l'etude 2013 sur la charge mondiale de morbidite. Pour la plupart des categories de traumatismes, une Incapacite a long terme a ete constatee.

Conclusion Un traumatisme constitue souvent un trouble chronique, et les estimations des charges de morbidite devraient refleter cet etat de fait. L'application de ces nouveaux coefficients de ponderation aux etudes sur les charges de morbidite devrait permettre de nettement ameliorer les evaluations des annees de vie ajustees sur l'incapacite et de refleter plus precisement l'impact des traumatismes sur la vie des individus. …
