National trends in utilization and in-hospital outcomes of surgical aortic valve replacements in spain, 2001-2015

Abstract Objective: The aims of this study were to examine the incidence and in-hospital outcomes of surgical aortic valve replacement (SAVR) and to identify factors associated with in-hospital mortality (IHM) among patients according to the type of implanted valve used in SAVR. Methods: We performed a retrospective study using the Spanish National Hospital Discharge Database, 2001-2015. We included patients who had SAVR listed as a procedure in their discharge report. Results: We identified 86,578 patients who underwent SAVR (52.78% mechanical and 47.22% bioprosthetic). Incidence of SAVR coding increased significantly from 11.95 cases per 100,000 inhabitants in 2001 to 17.92 in 2015 (P<0.001). Age and comorbidities increased over time (P<0.001). There was a significant increase in the frequency of concomitant coronary artery bypass grafting (CABG) and in the use of pacemaker implantation. The use of mechanical SAVR decreased and the use of bioprosthetic valves increased over time. IHM decreased over time (from 8.13% in 2001-05 to 5.39% in 2011-15). Patients who underwent mechanical SAVR had higher IHM than those who underwent bioprosthetic SAVR (7.44% vs. 6%; P<0.05). Higher IHM rates were associated with advanced age, female sex, comorbidities, concomitant CABG, and the use of mechanical SAVR (OR 1.67; 95% CI 1.57-1.77). Conclusion: The number of SAVRs performed in Spain has increased since 2001. The use of mechanical SAVR has decreased and the use of bioprosthetic valves has increased over time. IHM has decreased over time for both types of valves and despite a concomitant increase in age and comorbidities of patients during the same period.

Tendencies and outcomes in endoscopic biliary sphincterotomies among people with or without type 2 diabetes mellitus in Spain, 2003-2013

We aimed to compare incidence and outcomes for endoscopic biliary sphincterotomies in people with or without type 2 diabetes mellitus (T2DM) in Spain (2003-2013). We collected all cases of endoscopic biliary sphincterotomies using national hospital discharge data and evaluated annual incidence rates stratified by T2DM status. We analyzed trends over time for in-hospital mortality (IHM) as the primary outcome and a composite of IHM or procedure-related complications (key secondary outcome). In multivariate analyses, we tested T2DM as an independent factor of IHM and IHM or complications. We identified 126,885 endoscopic biliary sphincterotomies (23,002 [18.1%] in T2DM people). Crude incidence rates of endoscopic biliary sphincterotomies were > 3-fold higher in people with vs without T2DM (85.5/105 vs 26.9/105 population, respectively). Annual incidence rates of endoscopic biliary sphincterotomies showed 11-year relative increments of 77.5% (from 60.0 to 106.5/105) in T2DM, and 53.7% (from 21.6 to 33.2/105) in non-T2DM people (p < 0.001). We found no significant changes in mortality trends over time for the populations with or without T2DM (p = 0.15 and p = 0.21, respectively). Rates of procedural pancreatitis decreased in people without T2DM (p < 0.001). In the multivariate analysis, older age, higher comorbidity and endoscopic biliary sphincterotomy during urgent admission were associated with a higher IHM. T2DM was associated with a lower IHM after an endoscopic biliary sphincterotomy (OR = 0.82 [0.74-0.92]). Time trend multivariate analyses 2003-2013 showed significant reductions in IHM over time only in people with T2DM (OR = 0.97 [0.94-1.00]). Further studies are needed to confirm a lower IHM for endoscopic biliary sphincterotomies in people with T2DM (AU)

Infección por Clostridium difficile en el período 2005-2010 en los Servicios de Medicina Interna españoles: el peso de la enfermedad / Clostridium difficile infections in Spanish Internal Medicine departments during the period 2005-2010: the burden of the disease

INTRODUCCIÓN: La incidencia de la infección por Clostridium difficile (ICD) parece estar aumentando en España. Revisamos esta información para conocer qué supone la carga de esta enfermedad. Material: Estudio analítico retrospectivo descriptivo del conjunto mínimo básico de datos entre los pacientes dados de alta en Medicina Interna (MI) entre 2005 y 2010. Se comparan variables demográficas y clínicas entre pacientes con ICD y sin ICD. RESULTADOS: De 3.353.857 altas se identifican 7.247 casos de ICD (0,2%) con una edad mediana ± DE de 75,5 ± 15,4 años), 54,9% mujeres y estancia mediana de 22,2 ± 24,8. El coste (5.001 ± 4.985 Euros vs. 3.934 ± 2.738 Euros) y la complejidad diagnóstica (2,04 ± 2,62 vs. 1,67 ± 1,47) también varían. La mortalidad por todas las causas fue del 12,5% frente al 9,8%. El riesgo de muerte se incrementa un 30% (odds ratio 1,30; intervalo de confianza del 95%, 1,21-1,39) y la tasa de reingresos en los sujetos con ICD es del 30,4% vs. 13,5%. La distribución de los casos muestra estacionalidad (mayor en invierno) y la incidencia anual crece durante el período de estudio. Se asocian a un mayor riesgo de contraer una ICD: edad avanzada, ser mujer, ingreso prolongado y las comorbilidades: anemia, virus de la inmunodeficiencia humana, demencia, desnutrición, insuficiencia renal crónica o ingresar desde residencia. CONCLUSIÓN: Nuestros resultados demuestran claro impacto negativo de la ICD sobre el ingreso hospitalario e incremento el tiempo, algo compartido con Europa y el resto de Occidente, sin que mejoren los datos de morbimortalidad o reingresos

INTRODUCTION: Clostridium Difficile infection (CDI) is increasing in Spain. A review is presented of this infection in order to evaluate the burden of the disease in this country. Material: An analytical retrospective and descriptive study was conducted by analyzing the Minimum Basic Data Set of patients admitted to Internal Medicine Departments and with and without CDI between the years 2005-2010. Clinical and demographical variables were compared. RESULTS: Mean age was 75.5 years (SD 15.4), 54.9% were women and mean stay was 22.2 days (SD 24.8). The Cost [(Euros 5,001 (SD 4,985) vs [Euros 3,934 (SD 2,738)] and diagnostic complexity [2.04 (SD 2.62) vs [1.67 (SD 1.47)] were also different. Mortality for all causes was 12.5% vs 9.8%. Death risk showed a 30% increase (odds ratio 1.30, 95% confidence interval;1.21-1.39) and readmission rate was 30.4% vs 13.5%. Distribution of cases showed season variations (more cases in winter), and annual incidence increased during the study period. Comorbidities associated to increased risk of acquiring CDI were: anemia, human immunodeficiency virus, dementia, malnutrition, chronic renal failure, and living in a nursing home. CONCLUSIÓN: The results showed a clear negative impact of CDI on hospital admissions. A trend towards progression in its incidence without changes in mortality or readmission rates was observed, in common with the rest of Europe and the Western World

Ventilatory Support Use in Hospitalized Patients With Community-Acquired Pneumonia. Fifteen-year Trends in Spain (2001-2015) / Uso de soporte ventilatorio en pacientes hospitalizados por neumonía adquirida en la comunidad. Tendencias a lo largo de 15 años en España (2001-2015)

AIM: We examined fifteen years trends (2001-2015) in the use of non-invasive ventilation (NIV), invasive mechanical ventilation (IMV) or both (NIV+IMV) among patients hospitalized for community acquired pneumonia (CAP). We also analyzed trends overtime and the influence of patient factors in the in-hospital mortality (IHM) after receiving NIV, IMV or NIV + IMV. METHODS: Observational retrospective epidemiological study. Our data source was the Spanish National Hospital Discharge Database. RESULTS: Over a total of 1,486,240 hospitalized patients with CAP, we identified 56,158 who had received ventilator support in Spain over the study period. Of them, 54.82% received NIV, 37.04% IMV and 8.14% both procedures. The use of NIV and NIV + IMV increased significantly (p < 0.001) over time (from 0.91 to 12.84 per 100.000 inhabitant and from 0.23 to 1.19 per 100.000 inhabitants, respectively), while the IMV utilization decreased (from 3.55 to 2.79 per 100,000 inhabitants; p < 0.001). Patients receiving NIV were the oldest and had the highest mean value in the Charlson comorbidity index (CCI) score and readmission rate. Patients who received only IMV had the highest IHM. Factors associated with IHM for all groups analyzed included age, comorbidities and readmission. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV + IMV. CONCLUSIONS: We found an increase in NIV use and a decline in IMV utilization in patients hospitalized for CAP over the study period. Patients receiving NIV were the oldest and had the highest CCI score and readmission rate. IHM decreased significantly over time in patients with CAP who received NIV, IMV and NIV + IMV

OBJETIVO: Estudiamos las tendencias a lo largo de 15 años (2001-2015) en el uso de la ventilación no invasiva (VNI), la ventilación mecánica invasiva (VMI) o ambas (VNI + VMI) en los pacientes hospitalizados por neumonía adquirida en la comunidad (NAC). También analizamos las tendencias en el tiempo y la influencia de los factores del paciente en la mortalidad hospitalaria (MH) después de recibir VNI, VMI o VNI + VMI. MÉTODOS: Estudio epidemiológico retrospectivo observacional. Nuestra fuente de datos fue el Registro de Altas de los Hospitales (CMBD) del Sistema Nacional de Salud. RESULTADOS: En un total de 1.486.240 pacientes hospitalizados por NAC, identificamos a 56.158 que habían recibido soporte ventilatorio en España durante el período a estudio. De ellos, el 54,82% recibió VNI, el 37,04% VMI y el 8,14% ambos procedimientos. El uso de VNI y VNI + VMI aumentó significativamente (p < 0,001) con el tiempo (de 0,91 a 12,84 por habitante y de 0,23 a 1,19 por cada 100.000 habitantes, respectivamente), mientras que la utilización de la VMI disminuyó (de 3,55 a 2,79 por cada 100.000 habitantes; p < 0,001). Los pacientes que recibieron VNI fueron los más ancianos y presentaban el valor medio más alto de puntuación en el índice de comorbilidad de Charlson (CCI, por sus siglas en inglés) y en la tasa de reingreso. Los pacientes que recibieron solo VMI presentaron la MH más alta. Los factores asociados a la MH para todos los grupos analizados incluyeron la edad, las comorbilidades y el reingreso. La MH disminuyó significativamente con el tiempo en los pacientes con NAC que recibieron VNI, VMI y VNI + VMI. CONCLUSIONES: Encontramos un aumento en el uso de VNI y una disminución en la utilización de VMI en pacientes hospitalizados por NAC durante el período a estudio. Los pacientes que recibieron VNI fueron los más ancianos y tenían la puntuación más alta en el CCI y la tasa de reingreso más elevada. La MH disminuyó significativamente con el tiempo en los pacientes con NAC que recibieron VNI, VMI y VNI + VMI
