Trends in Prevalence of Diabetes among Twin Pregnancies and Perinatal Outcomes in Catalonia between 2006 and 2015: The DIAGESTCAT Study.

The aims of our study were to evaluate the trends in the prevalence of diabetes among twin pregnancies in Catalonia, Spain between 2006 and 2015, to assess the influence of diabetes on perinatal outcomes of twin gestations and to ascertain the interaction between twin pregnancies and glycaemic status. A population-based study was conducted using the Spanish Minimum Basic Data Set. Cases of gestational diabetes mellitus (GDM) and pre-existing diabetes were identified using ICD-9-CM codes. Data from 743,762 singleton and 15,956 twin deliveries between 2006 and 2015 in Catalonia was analysed. Among twin pregnancies, 1088 (6.82%) were diagnosed with GDM and 83 (0.52%) had pre-existing diabetes. The prevalence of GDM among twin pregnancies increased from 6.01% in 2006 to 8.48% in 2015 (p < 0.001) and the prevalence of pre-existing diabetes remained stable (from 0.46% to 0.27%, p = 0.416). The risk of pre-eclampsia was higher in pre-existing diabetes (15.66%, p = 0.015) and GDM (11.39%, p < 0.001) than in normoglycaemic twin pregnancies (7.55%). Pre-existing diabetes increased the risk of prematurity (69.62% vs. 51.84%, p = 0.002) and large-for-gestational-age (LGA) infants (20.9% vs. 11.6%, p = 0.001) in twin gestations. An attenuating effect on several adverse perinatal outcomes was found between twin pregnancies and the presence of GDM and pre-existing diabetes. As a result, unlike in singleton pregnancies, diabetes did not increase the risk of all perinatal outcomes in twins and the effect of pre-existing diabetes on pre-eclampsia and LGA appeared to be attenuated. In conclusion, prevalence of GDM among twin pregnancies increased over the study period. Diabetes was associated with a higher risk of pre-eclampsia, prematurity and LGA in twin gestations. However, the impact of both, pre-existing diabetes and GDM, on twin pregnancy outcomes was attenuated when compared with its impact on singleton gestations.

Trends in prevalence of pre-existing diabetes and perinatal outcomes: a large, population-based study in Catalonia, Spain, 2006-2015.

INTRODUCTION: This study aims to assess trends in the prevalence of pre-existing diabetes and whether the risk of adverse perinatal outcomes decreased in women between 2006 and 2015 in Catalonia, Spain. RESEARCH DESIGN AND METHODS: A population-based study of 743 762 singleton deliveries between 2006 and 2015 in Catalonia, Spain, was conducted using data from the Spanish Minimum Basic Data Set. Cases of type 1 diabetes (T1DM) and 'type 2 diabetes and other pre-existing diabetes' ('T2DM and other PGD') were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Crude and age-adjusted annual prevalences were calculated. Poisson regression model was used to assess trends in prevalence and perinatal outcomes during the study period. RESULTS: Overall prevalences of pre-existing diabetes, T1DM and 'T2DM and other PGD' were 0.52% (95% CI 0.51 to 0.54), 0.17% (95% CI 0.17 to 0.18) and 0.35% (95% CI 0.33 to 0.36), respectively. From 2006 to 2015, rates increased for pre-existing diabetes (from 0.43 (95% CI 0.39 to 0.48) to 0.56% (0.50 to 0.62), p<0.001), T1DM (from 0.14 (0.11 to 0.17) to 0.20% (0.17 to 0.23), p<0.001) and 'T2DM and other PGD' (from 0.29 (0.25 to 0.33) to 0.36% (0.31 to 0.40), p<0.001). Pre-eclampsia rose in women with pre-existing diabetes (from 4.38% to 8.97%, adjusted p<0.001), T1DM (from 3.85% to 12.88%, p=0.005) and 'T2DM and other PGD' (from 4.63% to 6.78%, adjusted p=0.01). Prevalence of prematurity, cesarean section and small for gestational age remained stable in all diabetes groups. However, the prevalence of macrosomia fell in women with pre-existing diabetes (from 18.18% to 11.9%, adjusted p=0.011) and 'T2DM and other PGD' (from 14.71% to 11.06%, non-adjusted p=0.022, adjusted p=0.305) and large for gestational age decreased in all diabetes groups (from 39.73% to 30.25% in pre-existing diabetes, adjusted p=0.004). CONCLUSIONS: The prevalence of pre-existing diabetes increased significantly in Catalonia between 2006 and 2015. Despite improvements in outcomes related to excessive birth weight, pre-eclampsia rates are rising and overall perinatal outcomes in women with pre-existing diabetes continue to be markedly worse than in the population without diabetes.

Trends in prevalence of gestational diabetes and perinatal outcomes in Catalonia, Spain, 2006 to 2015: the Diagestcat Study.

BACKGROUND: No recent epidemiologic studies on gestational diabetes mellitus (GDM) have been conducted in Spain. The present study aimed to explore trends in the prevalence of GDM and ascertain whether the risk of adverse perinatal outcomes changed between 2006 and 2015 in Catalonia. METHODS: In this population-based study, all hospital admissions for singleton births in Catalonia for the period 2006 to 2015 were collected from the Spanish Minimum Basic Data Set. Cases of GDM were identified from hospital delivery discharge reports using ICD-9-CM codes. Data regarding maternal characteristics and perinatal outcomes were analysed. Crude and age-adjusted annual prevalences were calculated. The Poisson regression model was used to assess trends in prevalence and perinatal outcomes, adjusted for age and smoking habit; however, they could not be adjusted for body mass index (BMI) and ethnicity. RESULTS: Data from 743 762 deliveries were collected. GDM prevalence over the study period was 4.80% (95% CI 4.75-4.85%). Crude GDM prevalence rose from 3.81% (95% CI 3.67-3.95%) in 2006 to 6.53% (95% CI 6.33-6.72%) in 2015 (P < 0.001). Women with GDM showed a stable trend in rates of preeclampsia (2.56%), prematurity (15.7%), and large-for-gestational age (LGA) newborns (18.3%), whereas a lower rate of macrosomia was observed during the study period (from 9.16% to 7.84%). Caesarean deliveries rose from 28% to 31%; however, significance was lost after adjustment. CONCLUSIONS: The prevalence of GDM in Catalonia almost doubled between 2006 and 2015. During the study period, the frequency of macrosomia decreased whereas pre-eclampsia, prematurity, LGA, and age-adjusted Caesarean rates remained stable.

Impacto económico de los eventos adversos en los hospitales españoles a partir del Conjunto Mínimo Básico de Datos / Assessing the economic impact of adverse events in Spanish hospitals by using administrative data

Objetivo Evaluar la incidencia y los costes de los eventos adversos presentes en el Conjunto Mínimo Básico de Datos (CMBD) en los hospitales españoles en el período 2008-2010.MétodoEstudio retrospectivo que estima el coste incremental por episodio, según la presencia de eventos adversos. El coste se obtiene de la Red Española de Costes Hospitalarios (RECH), creada a partir de los registros de costes por paciente basados en actividades y CMBD. Los eventos adversos se han identificado mediante Indicadores de Seguridad del Paciente (validados en el Sistema Sanitario español) de la Agency of Healthcare Research and Quality, junto a indicadores del proyecto europeo EuroDRG. Resultados Se incluyen 245.320 episodios, con un coste de 1.308.791.871 Euros. Aproximadamente 17.000 episodios (6,8%) sufrieron un evento adverso, lo que representa un 16,2% del coste total. Los eventos adversos, ajustados por el Grupo Relacionado por el Diagnóstico, añaden un coste incremental medio que oscila entre 5.260 Euros y 11.905 Euros. Seis de los diez eventos adversos con mayor coste incremental son posteriores a intervenciones quirúrgicas. El coste incremental total de los eventos adversos es de 88.268.906Euros, un 6,7% adicional del total del gasto sanitario. Conclusiones Valorando su impacto, los eventos adversos representan relevantes costes que pueden revertirse en mejora de la calidad y la seguridad del sistema de salud (AU)

Objective To evaluate the incidence and costs of adverse events registered in an administrative dataset in Spanish hospitals from 2008 to 2010.MethodsA retrospective study was carried out that estimated the incremental cost per episode, depending on the presence of adverse events. Costs were obtained from the database of the Spanish Network of Hospital Costs. This database contains data from 12 hospitals that have costs per patient records based on activities and clinical records. Adverse events were identified through the Patient Safety Indicators (validated in the Spanish Health System) created by the Agency for Healthcare Research and Quality together with indicators of the EuroDRG European project. Results This study included 245,320 episodes with a total cost of 1,308,791,871 Euros. Approximately 17,000 patients (6.8%) experienced an adverse event, representing 16.2% of the total cost. Adverse events, adjusted by diagnosis-related groups, added a mean incremental cost of between Euros 5,260 and Euros11,905. Six of the 10 adverse events with the highest incremental cost were related to surgical interventions. The total incremental cost of adverse events was Euros 88,268,906, amounting to an additional 6.7% of total health expenditure. Conclusions Assessment of the impact of adverse events revealed that these episodes represent significant costs that could be reduced by improving the quality and safety of the Spanish Health System (AU)
