[Correspondences from 10th to 9th Revision of the International Classification of Diseases in the causes of death lists of the National Institute of Statistics and the Regional Health Authority of Murcia in Spain]. / Correspondencias entre CIE-10 y CIE-9 para las listas de causas de muerte del Instituto Nacional de Estadística y de la Región de Murcia.

BACKGROUND: Different countries have conducted comparability studies between Revisions 10 and 9 of the International Classification of Diseases for aggregate lists of causes of death. In Spain, the COMPARA project was aimed at evaluating the impact of the revision change. METHODS: Descriptive cross-sectional epidemiological study of 88,048 deaths recorded in Spain in 1999 with the underlying cause of death doubled coded in ICD-9 and ICD-10. The theoretical correspondences between the ICD on the lists of the National Institute of Statistics and Murcia are established. The comparability rates and their confidence intervals, and the total kappa index were calculated. RESULTS: A decline in infectious diseases (-1.7%) and viral hepatitis, (-12.3%) declined under Tenth revision, while AIDS showed an increase (5.7%). Neoplasms increased a little (0.3%) with the inclusion of the Mielodisplasic Syndrome (55.2%). Diabetes mellitus is increased (2.1%). Mental disorders declined on dementia being shifted to Alzheimer's disease (28.6%). Cardiovascular diseases dropped slightly (-1.4%), without any impact on cerebrovascular diseases, although acute myocardial infarct decreased (-0.6%) while ischemic heart disease increased (0.3%). Pneumonia decreased (-12.5%) and hepatic cirrhosis grows (4.3%). Ill-defined conditions increased due to cardiorespiratory insufficiencies. The external causes show no change without including the accuracy of ICD-9. The National Institute of Statistics 102 groups list obtained a total kappa index of 95.4%, similar to the Murcia variants. CONCLUSIONS: Although ICD-10 has a lesser overall impact, the significant comparability rates of the causes of death groups between the revisions with important absolute differences should be taken into account.

Fundamento: Diversos países han realizado estudios de comparabilidadentre las revisiones 10ª y 9ª de la Clasificación Internacionalde Enfermedades para listas agregadas de causas de muerte. EnEspaña el proyecto COMPARA pretende evaluar el impacto delcambio de revisión.Métodos: Estudio epidemiológico transversal descriptivo de88.048 defunciones inscritas en 1999 en España con la causa demuerte doblemente codificada en CIE-9 y 10. Se establecen lascorrespondencias teóricas entre CIE en las listas INE y Murcia. Secalculan las razones de comparabilidad e intervalos de confianza y elíndice kappa global.Resultados: Descienden las enfermedades infecciosas (-1,7%),las hepatitis víricas (-12,3%), mientras que aumenta el Sida (5,7%).Las neoplasias aumentan el 0,3% por la incorporación del síndromemielodisplásico (55,2%). Se incrementa la diabetes mellitus (2,1%).Se reducen los trastornos mentales al salir las demencias hacia laenfermedad de Alzheimer (28,6%). Las enfermedades cardiovascularesdescienden ligeramente (-1,4%), sin impacto sobre las cerebrovasculares,aunque el infarto agudo de miocardio decrece (-0,6%)con aumento de la enfermedad isquémica cardiaca (0,3%). La neumoníadecrece (-12,5%) y la cirrosis hepática se aumenta (4,3%).Las entidades mal definidas aumentan por la cesión de las insuficienciascardiorrespiratorias. Las causas externas no varían sin querecojan la precisión de la CIE-9. La lista INE - 102 grupos obtiene uníndice kappa del 95,4%, similar a las variantes de Murcia. Conclusiones: Aunque el impacto global de la CIE-10 es menor,se deberían tener en cuenta las razones de comparabilidad significativasde los grupos de causas de muerte con diferencias absolutasimportantes entre las revisiones
