[Perinatal mortality according to 2 information sources]. / La mortalidad perinatal según 2 fuentes de información.

OBJECTIVE: To evaluate differences in the number of cases of perinatal mortality in Catalonia (Spain) recorded in 2 health information systems, as well as trends in this phenomenon. METHODS: Data were obtained from the mortality statistics (Health Department and the Catalan Institute of Statistics) and the minimum data set (MDS) for hospital discharges of the Catalan Health Service from 2000-2003. The frequencies are given for the cases reported and for cases following the legal criteria for reporting. RESULTS: The mortality statistics registered 27.2% fewer perinatal deaths, 44.77% fewer fetal deaths and 13.5% more early neonatal deaths than the MDS. These percentages were lower when only the cases following the legal criteria for reporting were considered. CONCLUSION: The differences between the two sources were related to low birth weight, prematurity, and the place of occurrence. Use of hospital data might improve the quality of perinatal mortality statistics.

[Health system interventions assessment in Spain: an approach through the analysis of the time trends and the geographical variability of avoidable mortality between 1986 -2001]. / Medida del resultado de las intervenciones sanitarias en España: una aproximación mediante el análisis temporal y espacial de la mortalidad evitable entre 1986-2001.

BACKGROUND: Many studies have proposed Avoidable Mortality (ME) to monitor the performance of health services although its usefulness is limited by the multiplicity of the avoidable mortality lists being used. Time trends from 1986-2001 and the geographical distribution of avoidable mortality by provinces, are presented for Spain. METHODS: An Avoidable Mortality consensus list is being used. It includes avoidable mortality through the intervention of health services (ISAS in Spanish) and through health policy interventions (IPSI in Spanish). Time trends are analyzed adjusting Poisson or Joinpoint regression models and the annual percentages of change (APC) are estimated. Changes in geographical distribution between the first half of the analysed period and the second are tested by means of standard mortality ratios (SMR) and comparative mortality rates (CMR) for each province. RESULTS: Between 1986 and 2001 avoidable mortality decreased (APC: -1.68; CI: -1.99 and -1.38) slightly more than non-avoidable mortality (APC: -1.28; CI: -1.40 and -1.17). Higher reduction was observed for ISAS mortality (APC: -2.77; CI: -2.89 and -2.65) and an irregular trend for IPSI (between 1986-1990 increase APC: 4.86; CI: 3.32 and 6.41, between 1990-95 stabilization APC: -0.03; CI: -2.32 and 2.31 and finally 1995-2001 decrease APC: -3.57; CI: -4.72 and -2.40). CONCLUSIONS: Avoidable mortality decreased more than non avoidable mortality and important geographical variability can be observed among provinces which should be monitored in order to identify the health services weaknesses. The higher ISAS mortality was observed in southern provinces and the higher IPSI mortality in some areas on the coast. The pattern is somewhat similar for both analyzed periods.

Las muertes con intervención judicial y medicolegal y su impacto en la estadística de causas de muerte en Cataluña / Deaths with medicolegal intervention and its impact on the cause-of-death statistics in Catalonia, Spain

Introducción. Los boletines estadísticos correspondientes a las defunciones que requieren intervención judicial (DIJ) y actuación forense contienen un número elevado de causas de muerte mal definidas. El objetivo es presentar los resultados de la recuperación de datos a partir de las autopsias judiciales del año 2013 en Cataluña y analizar el impacto de esta información sobre la estadística de causas de muerte. Material y métodos. Se seleccionaron del Registro de Mortalidad de Cataluña las defunciones con intervención judicial que tenían como causa de muerte unas determinadas afecciones mal definidas, según criterios de codificación de la OMS. Se recuperó la información de los registros de autopsia de los centros de Patología Forense del Instituto de Medicina Legal y Ciencias Forenses de Cataluña (IMLCFC). Resultados. Las DIJ representan el 6% de la mortalidad total de Cataluña, el 42,9% de las causas externas y el 77% de las mal definidas. De los 3.639 casos de DIJ del año 2013 se revisó un 43,4% (n=1.578) y se obtuvo información que mejoró la causa de muerte del 78,4% de los revisados. La información recuperada aumentó un 61,3% las intoxicaciones accidentales, un 32,6% los suicidios, un 28,9% los homicidios, un 27,4% las caídas, un 22,7% los accidentes de tráfico y un 5,2% la cardiopatía isquémica, con el equivalente aumento de las tasas de mortalidad por estas causas. Conclusiones. La información de las autopsias judiciales tiene un gran impacto en las estadísticas de causa de muerte, especialmente en las causas externas y la cardiopatía isquémica. Un informe forense sobre la causa y las circunstancias de la muerte, de manera que permita fácilmente su codificación posterior, así como la transmisión directa de estos datos a la oficina estadística serían la mejor solución para evitar la pérdida de información que se produce actualmente (AU)

Introduction. The statistical forms corresponding to deaths that require judicial and forensic interventions contain a very high number of ill-defined causes of death. The objective is to show the results of data recovery from the forensic autopsies and to analyse the impact of this information on the cause-of-death statistics for the year 2013 in Catalonia (Spain). Material and methods. Deaths with judicial intervention with an ill-defined cause of death according to the WHO coding standards were selected from the Catalan Mortality Registry. Information was recovered from the autopsy registers of the Forensic Pathology centres of the Institute of Legal Medicine and Forensic Science of Catalonia (IMLCFC). Results. Deaths with judicial intervention represent 6% of total mortality in Catalonia, 42.9% due to external causes and 77% pertaining to ill-defined causes-of-death. There were 3,639 cases of death with judicial intervention, of which 43.4% (n=1,578) were reviewed, resulting in information that improved the cause of death in 78.4% of cases. The information retrieved increased accidental poisoning by 61.3%, suicides by 32.6%, homicides by 28.9%, falls by 27.4%, traffic accidents by 22.7% and ischaemic heart disease by 5.2%, with the equivalent increase in the mortality rates from these causes. Conclusions. The forensic autopsy information has a significant impact on cause-of-death statistics, especially external causes and ischemic heart disease. A forensic report concerning the cause and circumstances of death, structured to facilitate further coding and the direct transmission of data to the statistical office, would be the best solution to prevent the loss of information currently experienced (AU)

La mortalidad perinatal según 2 fuentes de información / Perinatal mortality according to 2 information sources

Objetivo: Evaluar la diferencia en muertes perinatales (MP) ocurridas en Cataluña y su evolución según 2 fuentes de información sanitaria.Métodos: Los datos proceden de la estadística de mortalidad (Departament de Salut e Institut d’Estadística de Catalunya) y del Conjunto Mínimo Básico de Datos de Altas Hospitalarias (CMBDAH) del Servei Català de la Salut del período 2000-2003. Se describen las frecuencias totales de MP según si cumplen o no criterio legal de declaración.Resultados: La estadística de mortalidad registró un 27,2% menos de MP, un 44,77% menos de muertes fetales y un 13,5% más de muertes neonatales precoces que el CMBDAH. Estos porcentajes son menores considerando sólo los casos con criterios legales de declaración.Conclusión: Las diferencias de casos entre ambas fuentesestán relacionadas con características del recién nacido: bajo peso al nacer, prematuridad y lugar en que se produjo. Los datos hospitalarios podrían mejorar la estadística de mortalidad perinatal

Medida del resultado de las intervenciones sanitarias en España: una aproximación mediante el análisis temporal y espacial de la mortalidad evitable entre 1986-2001 / Health system interventions assessment in Spain: an approach through the analysis of the time trends and the geographical variability of avoidable mortality between 1986 -2001

Fundamento: Muchos estudios proponen la mortalidad evitable(ME) como indicador para monitorizar los servicios de salud aunquesu generalización está limitada por el gran número de listas de causasutilizadas. El objetivo es analizar la evolución temporal del período1986-2001 y la distribución geográfica de la mortalidad evitable utilizandouna lista de causas consensuada.Métodos: Se analiza la mortalidad evitable global (ME) y agrupadaen causas ISAS (intervenciones de los servicios sanitarios) ycausas IPSI (políticas intersectoriales). Se analiza la evolución temporalajustando una recta de regresión de Poisson o un modelo deregresión de Joinpoint, según el caso, y se estima el porcentaje decambio anual (PCA). Para la distribución geográfica se calculan losíndices de mortalidad estandarizada (IME) por provincia y la razónde mortalidad comparativa (RMC) de cada provincia entre la primeray la segunda parte del periodo temporal.Resultados: Entre 1986-2001 la mortalidad evitable se redujo(PCA -1,68; IC:-1,99 a -1,38) algo más que la no-evitable (PCA -1,28; IC:-1,40 a -1,17). La mayor disminución se observó en la mortalidadpor causas ISAS (PCA del -2,77; IC: -2,89, -2,65) mientrasque la mortalidad por causas IPSI aumentó entre 1986-1990 (PCAdel 4,86; IC: 3,32 y 6,41), se mantiene constante de 1990-1995 (PCAdel -0,03; IC: -2,32 y 2,31) y disminuyó de 1995-2001 (PCA del -3,57; IC: -4,72 y -2,40). Conclusiones: Durante el período estudiado la mortalidad evitableha tenido una reducción mayor que la no evitable y se observandiferencias importantes entre provincias que sería necesario monitorizarpara tratar de identificar posibles disfunciones en los serviciossanitarios. La mortalidad es superior por causas ISAS en la zona surde España y por causas IPSI en algunas provincias costeras y estepatrón no varió mucho en el período analizado
