RESUMO
Normothermic regional perfusion (NRP) allows the in situ perfusion of organs with oxygenated blood in donation after the circulatory determination of death (DCDD). We aimed at evaluating the impact of NRP on the short-term outcomes of kidney transplants in controlled DCDD (cDCDD). This is a multicenter, nationwide, retrospective study comparing cDCDD kidneys obtained with NRP versus the standard rapid recovery (RR) technique. During 2012-2018, 2302 cDCDD adult kidney transplants were performed in Spain using NRP (n = 865) or RR (n = 1437). The study groups differed in donor and recipient age, warm, and cold ischemic time and use of ex situ machine perfusion. Transplants in the NRP group were more frequently performed in high-volume centers (≥90 transplants/year). Through matching by propensity score, two cohorts with a total of 770 patients were obtained. After the matching, no statistically significant differences were observed between the groups in terms of primary nonfunction (p = .261) and mortality at 1 year (p = .111). However, the RR of kidneys was associated with a significantly increased odds of delayed graft function (OR 1.97 [95% CI 1.43-2.72]; p < .001) and 1-year graft loss (OR 1.77 [95% CI 1.01-3.17]; p = .034). In conclusion, compared with RR, NRP appears to improve the short-term outcomes of cDCDD kidney transplants.

AIM: This study assessed the risks associated with healthy late preterm infants and healthy term-born infants using national hospital discharge records. METHOD: We used the minimum basic data set of the Spanish hospital discharge records database for 2012-2013 to analyse the hospitalisation of newborn infants. The outcomes were in-hospital mortality and hospital re-admissions at 30 days and one year after their first discharge. RESULTS: Of the 95 011 newborn infants who were discharged, 2940 were healthy late preterm infants, born at 34 + 0-36 + 6 weeks, and 18 197 were healthy term-born infants. The mean and standard deviation (SD) length of hospital stay were 6.0 (4.5) days in late preterm infants versus 2.8 (1.3) days in term-born infants (p < 0.001). Re-admissions were also higher in the late preterm group at 30 days (9.0% versus 4.4%) and one year (22.0% versus 12.4) (p < 0.001). The relative risk for death at one year was 4.9 in the late preterm group, when compared to the term-born infants (p = 0.026). CONCLUSION: The hospital discharge codes for otherwise healthy newborn preterm infants were associated with significantly worse 30-day and one-year outcomes when their re-admission and mortality rates were compared with healthy term-born newborn infants.
RESUMO
INTRODUCTION AND OBJECTIVES: Conflicting results have been reported on the possible existence of sex differences in mortality after myocardial infarction (MI). There is also a scarcity of data on the impact of sex on outcomes after ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI). The aim of this study was to analyze sex difference trends in sex-related differences in mortality for STEMI and NSTEMI. METHODS: A retrospective analysis of 445 145 episodes of MI (2005-2015) was carried out using information from the Spanish National Health System. The incidence rates were expressed as events per 10 000 person-years. The denominators (age-specific groups) were obtained from the nationwide census. We calculated crude and adjusted (multilevel logistic regression) mortality. Poisson regression analysis was used to study temporal trends for in-hospital mortality. RESULTS: A total of 69.8% episodes occurred in men. The mean age in men was 66.1±13.3 years, which was significantly younger than in women, 74.9±12.1 (P<.001). A total of 272 407 (61.2%) episodes were STEMI, and 172 738 (38.8%) were NSTEMI. Women accounted for 28.8% of STEMI and 33.9% of NSTEMI episodes (P <.001). The effect of female sex on risk-adjusted models for in-hospital mortality was the opposite in STEMI (OR for women, 1.18; 95%CI, 1.14-1.22; P <.001) and NSTEMI (OR for women, 0.85; 95%CI, 0.81-0.89; P <.001). MI hospitalization rates were higher in men than in women for all age groups [20 vs 7.7 per 10 000 individuals aged 35-94 years (P <.001)], with a trend to diminish in both sexes. CONCLUSIONS: Women had a slight but significantly increased risk of in-hospital mortality after MI, but the effect of sex depended on MI type, with women exhibiting higher mortality for STEMI and lower mortality for NSTEMI.

INTRODUCTION AND OBJECTIVES: There are few data on the safety of length of stay in uncomplicated ST-segment elevation myocardial infarction. We studied trends in hospital stay and the safety of short (≤ 3 days) vs long hospital stay in Spain. METHODS: Using data from the Minimum Basic Data Set, we identified patients with uncomplicated ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and who were discharged alive between 2003 and 2015. The mean length of stay was adjusted by multilevel Poisson regression with mixed effects. The effect of short length of stay on 30-day readmission for cardiac diseases was evaluated in episodes from 2012 to 2014 by propensity score matching and multilevel logistic regression. We also compared risk-standardized readmissions for cardiac diseases and mortality rates. RESULTS: The adjusted length of stay decreased significantly (incidence rate ratio <1; P <.001) for each year after 2003. Short length of stay was not an independent predictor of 30-day readmission (OR, 1.10; 95%CI, 0.92-1.32) or mortality (OR, 1.94; 95%CI, 0.93-14.03). After propensity score matching, no significant differences were observed between short and long hospital stay (OR, 1.26; 95%CI, 0.98-1.62; and OR, 1.50; 95%CI, 0.48-5.13), respectively. These results were confirmed by comparisons between risk-standardized readmissions for cardiac disease and mortality rates, except for the 30-day mortality rate, which was significantly higher, although probably without clinical significance, in short hospital stays (0.103% vs 0.109%; P <.001). CONCLUSIONS: In Spain, hospital stay ≤ 3 days significantly increased from 2003 to 2015 and seems a safe option in patients with uncomplicated ST-segment elevation myocardial infarction.

INTRODUCTION AND OBJECTIVES: To analyze the association between volume and outcomes in coronary artery bypass grafting (CABG) in the Spanish National Health System. METHODS: We analyzed CABG episodes from 2013 to 2015. The selected outcome variables were in-hospital mortality in the index episode, 30-day cardiac-related readmissions, and mortality during readmission. Risk-adjusted rates of in-hospital mortality (RAMR) and 30-day readmissions (RARR) were calculated using multilevel logistic regression. High- and low-volume hospitals for CABG were identified by a nonconditioned analysis (k-means) and by compliance with the volume recommendation of clinical practice guidelines. RESULTS: A total of 17 335 CABG index episodes were included, with a crude in-hospital mortality rate of 5.0%. Episodes attended in low-volume centers for CABG (< 155 CABG per year) showed 17% higher RAMR (5.81%±2.07% vs 4.96%±1.76%; P <.001) and a negative linear correlation between volume and RARR (r=-0.318; P=.029), as well as a higher percentage of complications during the episode. The same association between volume and more favorable outcomes was found in isolated CABG. CONCLUSIONS: The mean CABG volume is low in Spanish National Health System hospitals. Higher volume was associated with better outcomes in CABG, both total and isolated. The findings of this study indicate the need for a higher concentration of CABG programs, as well as the publication of risk-adjusted outcomes of coronary intervention.

BACKGROUND: We aimed to assess the impact of implementation of reperfusion networks, the type of hospital and specialty of the treating physician on the management and outcomes of ST segment elevation myocardial infarction in patients aged ⩾75 years. METHODS: We analysed data from the Minimum Basic Data Set of the Spanish public health system, assessing hospital discharges between 2004 and 2013. Discharges were distributed in three groups depending on the clinical management: percutaneous coronary intervention, thrombolysis or no reperfusion. Primary outcome measure was all cause in-hospital mortality. For risk adjustment, patient comorbidities were identified for each index hospitalization. RESULTS: We identified 299,929 discharges, of whom 107,890 (36%) were in-patients aged ⩾75 years. Older patients had higher prevalence of comorbidities, were less often treated in high complexity hospitals and were less frequently managed by cardiologists ( p<0.001). Both percutaneous coronary intervention and fibrinolysis were less often performed in elderly patients ( p<0.001). A progressive increase in the rate of percutaneous coronary intervention was observed in the elderly across the study period (from 17% in 2004 to 45% in 2013, p<0.001), with a progressive reduction of crude mortality (from 23% in 2004 to 19% in 2013, p<0.001). Adjusted analysis showed an association between being treated in high complexity hospitals, being treated by cardiologists and lower in-hospital mortality ( p <0.001). CONCLUSIONS: Elderly patients with ST segment elevation myocardial infarction are less often managed in high complexity hospitals and less often treated by cardiologists. Both factors are associated with higher in-hospital mortality.

INTRODUCTION AND OBJECTIVES: To analyze the association between the development of network systems of care for ST-segment elevation myocardial infarction (STEMI) in the autonomous communities (AC) of Spain and the regional rate of percutaneous coronary intervention (PCI) and in-hospital mortality. METHODS: From 2003 to 2012, data from the minimum basic data set of the Spanish taxpayer-funded health system were analyzed, including admissions from general hospitals. Diagnoses of STEMI and related procedures were codified by the International Diseases Classification. Discharge episodes (n = 302 471) were distributed in 3 groups: PCI (n = 116 621), thrombolysis (n = 46 720), or no reperfusion (n = 139 130). RESULTS: Crude mortality throughout the evaluation period was higher for the no-PCI or thrombolysis group (17.3%) than for PCI (4.8%) and thrombolysis (8.6%) (P < .001). For the aggregate of all communities, the PCI rate increased (21.6% in 2003 vs 54.5% in 2012; P < .001) with a decrease in risk-standardized mortality rates (10.2% in 2003; 6.8% in 2012; P < .001). Significant differences were observed in the PCI rate across the AC. The development of network systems was associated with a 50% increase in the PCI rate (P < .001) and a 14% decrease in risk-standardized mortality rates (P < .001). CONCLUSIONS: From 2003 to 2012, the PCI rate in STEMI substantially increased in Spain. The development of network systems was associated with an increase in the PCI rate and a decrease in in-hospital mortality.

BACKGROUND: Acute myocardial infarction (AMI) is a common cause of hospital discharges and readmissions. Readmissions may indicate poor patient care and avoidable health expenditure, being key in quality improvement strategies. Our aim was to analyse cardiac diseases (CDs) readmissions in patients with AMI in Spain. METHODS: A retrospective analysis of 33,538 hospital discharges with AMI being the "principal diagnosis" at hospitals of the Spanish National Health System in 2012 was performed using administrative data. We developed a logistic regression model and calculated 30-day, 3-month and 1-year CDs risk-standardized readmission rates (RSRRs) using a multivariate mixed model. RESULTS: Variables of the model (AMI location, age, previous angina pectoris/myocardial infarction or acute coronary syndrome, chronic kidney disease, rheumatic valvular disease, diabetes mellitus, vascular disease, female sex, chronic pulmonary disease, and anemia) were able to predict 30-day, 3-month and 1-year readmission rates and RSRRs after AMI (5.4%, 9.3% and 20.2%, respectively). For RSRRs the area under the ROC curve was 0.74 (p=0.0037), 0.77 (p=0.0041), and 0.73 (p=0.0025) for 1, 3months and 1-year readmission rate, respectively. Angioplasty, cardiology as the medical unit responsible for the discharge and a higher volume of activity (>204 AMI) were all significantly (p<0.001) associated with lower mortality, risk of development of heart failure and RSRRs. CONCLUSIONS: Angioplasty, cardiology as the medical unit responsible for the discharge and a higher volume of activity explain variability in CDs readmission rates after AMI, which can have implications for strategies to reduce readmissions rates.

BACKGROUND: Little information exists regarding population-based epidemiological changes in infective endocarditis (IE) in Europe. OBJECTIVES: This study sought to analyze temporal trends in IE in Spain from 2003 to 2014. METHODS: This retrospective, population-based, temporal trend study analyzed the incidence, epidemiological and clinical characteristics, and outcome of all patients discharged from hospitals included in the Spanish National Health System with a diagnosis of IE, from January 2003 to December 2014. RESULTS: Overall, 16,867 episodes of IE were identified during the study period, 66.3% in men. The rate of IE significantly increased, from 2.72 in 2003 to 3.49 per 100,000 person-years in 2014, and this rise was higher among older adults. The most frequent microorganisms were staphylococci (28.7%), followed by streptococci (20.4%) and enterococci (13.1%). Twenty-three percent of patients underwent cardiac surgery. The in-hospital mortality rate was 20.4%. Throughout the study period, the proportion of patients with previously known heart valve disease and diabetes mellitus significantly increased, whereas the prevalence of intravenous drug use decreased. Regarding microorganisms, Staphylococcus aureus and streptococci slightly declined, whereas coagulase-negative staphylococci and enterococci consistently increased over the years. In-hospital complications and cardiac surgery rates significantly increased across the years. The risk-adjusted in-hospital mortality rate diminished (0.2% per year) during the study period. CONCLUSIONS: The incidence of IE episodes significantly increased over the decade of the study period, particularly among older adults. Relevant changes in clinical and microbiological profile included older patients with more comorbidity and a rise in enterococci and coagulase-negative staphylococcal infections. Adjusted mortality rates slightly declined over the study period.

OBJECTIVE: To analyze trends in health outcomes and the influence of risk factors in children under 1 year with acute bronchiolitis due to respiratory syncytial virus (RSV bronchiolitis). A risk-adjustment model for RSV bronchiolitis in-hospital mortality was also developed. RESEARCH DESIGN AND METHODS: Retrospective study of hospitalizations for RSV bronchiolitis in children aged <1 year from 2004 to 2012. We used nationally representative data from the Spanish National Health Service records. RESULTS: Over the study period, the annual hospital discharges for RSV bronchiolitis ranged between 6390 and 8637. The annual in-hospital mortality rate ranged from 120 (2004) to 69 (2012) per 100,000 hospitalizations and the mean length of stay decreased steadily from 6.5 to 5.2 days (p < 0.001); 98.3% of hospitalizations for RSV bronchiolitis were children without risk factors. The in-hospital mortality rate due to RSV bronchiolitis in children with risk factors was 18.8 times higher than non-high-risk children and, in adjusted analyses, the OR of in-hospital mortality due to RSV bronchiolitis was higher than that due to other causes. LIMITATIONS: This study is a retrospective analysis, based on administrative data. It does not include data about pre- or in-hospital treatments, and has the limitations inherent in procedures for determining risk-adjusted mortality rates. Socioeconomic and environmental factors have not been considered in this study. CONCLUSIONS: RSV bronchiolitis is a leading cause of hospitalizations for infants under 1 year and has not shown incidence reduction over a 9 year period. Risk factors increase the in-hospital mortality risk and it is higher if the hospitalization cause is RSV bronchiolitis than any other reason.

Introducción y objetivos: Hay resultados contradictorios sobre si existen diferencias de sexo en la mortalidad tras el infarto agufo de miocardio (IAM). Además, hay escasez de datos sobre el impacto del sexo en los resultados tras un infarto agudo de miocardio con elevación del segmento ST (IAMCEST) o sin elevación del segmento ST (IAMSET). El objetivo de este estudio es analizar las tendencias de diferencias de sexo en las diferencias de mortalidad relacionadas con el sexo para IAMCEST e IAMSEST. Métodos: Se ha realizado un análisis retrospectivo de 445.145 episodios de IAM (2005-2015) utilizando información del Sistema Nacional de Salud español. Las tasas de incidencia se expresan como eventos por 10.000 personas-año. Los denominadores (grupos específicos por edad) se han obtenido del censo nacional. Se ha calculado la mortalidad bruta y ajustada (regresión logística multinivel) y se ha utilizado análisis de regresión de Poisson para estudiar las tendencias temporales de la mortalidad hospitalaria. Resultados: El 69,8% eran varones, con una edad media de 66,1 (13,3) años, significativamente más joven que las mujeres 74,9 (12,1) (p <0,001). Un total de 272.407 (61,2%) episodios son IAMCEST y 172.738 (38,8%) IAMSEST. Las mujeres son el 28,8% de IAMCEST y el 33,9% de los IAMSEST (p <0,001). En los modelos de ajuste de riesgo de mortalidad hospitalaria el efecto del sexo femenino es opuesto en IAMCEST (OR para mujeres=1,18; IC95%, 1,14-1,22; p <0,001) y IAMSEST (OR para mujeres:=0,85; IC95%, 0,81-0,89; p <0,001). Las tasas de hospitalización por IAM son más altas en varones que en mujeres para todos los grupos de edad [20 frente a 7,7 por cada 10.000 35-94 años (p <0,001)], con una tendencia a disminuir para ambos sexos...

INTRODUCTION AND OBJECTIVES: To investigate the relationship between in-hospital mortality due to acute myocardial infarction and type of hospital, discharge service, and treatment provided. METHODS: Retrospective analysis of 100 993 hospital discharges with a principal diagnosis of myocardial infarction in hospitals of the Spanish National Health Service. In-hospital mortality was adjusted for risk following the models of the Institute for Clinical Evaluative Sciences (Canada) and the Centers for Medicare & Medicaid Services (United States). RESULTS: Hospital characteristics are relevant to explain the variation in the individual probability of dying from myocardial infarction (median odds ratio: 1.3561). The risk-adjusted in-hospital mortality in cluster 3 and especially in cluster 4 hospitals (500 beds to 1000 beds and medium-high complexity) was significantly lower than in hospitals with less than 200 beds. Cluster 5 (more than 1000 beds), which includes a diverse group of hospitals, had a higher mortality rate than clusters 3 and 4. The adjusted mortality in the groups with the best and worst outcomes was 6.74% (cluster 4) and 8.49% (cluster 1), respectively. Mortality was also lower when the cardiology unit was responsible for the discharge or when angioplasty had been performed. CONCLUSIONS: The typology of the hospital, treatment in a cardiology unit, and percutaneous coronary intervention are significantly associated with the survival of a patient hospitalized for myocardial infarction. We recommend that the Spanish National Health Service establish health care networks that favor percutaneous coronary intervention and the participation of cardiology units in the management of patients with acute myocardial infarction.

Introducción y objetivos: Analizar la asociación entre la implementación de redes de reperfusión en el infarto agudo de miocardio con elevación del segmento ST (IAMCEST) en las comunidades autónomas (CC.AA.) españolas, la tasa regional de intervención coronaria percutánea (ICP) y la mortalidad hospitalaria. Métodos: Se analizaron las altas hospitalarias del Sistema Nacional de Salud entre 2003 y 2012. El diagnóstico de IAMCEST y los procedimientos relacionados se codificaron mediante la Clasificación Internacional de Enfermedades. Las altas se clasificaron en 3 grupos: ICP (n = 116.621), trombolisis (n = 46.720) o sin reperfusión (n = 139.130). Resultados: La mortalidad no ajustada fue superior entre los pacientes no sometidos a ICP o fibrinolisis (17,3%) que entre los sometidos a ICP (4,8%) o fibrinolisis (8,6%) (p < 0,001). Se apreció un aumento en la tasa de ICP en el conjunto de CC.AA. (el 21,6% en 2003 frente al 54,5% en 2012; p < 0,001), con una reducción en la tasa de mortalidad estandarizada por riesgo (el 10,2% en 2003 y el 6,8% en 2012; p < 0,001). Se apreciaron diferencias significativas entre las tasas de ICP de las CC.AA. La implementación de redes de reperfusión se asoció con un aumento en la tasa de ICP del 50% (p < 0,001) y una reducción del 14% de la tasa de mortalidad estandarizada por riesgo (p < 0,001). Conclusiones: Entre 2003 y 2012 se produjo en España un aumento significativo de la tasa de ICP en el IAMCEST. La implementación de redes de reperfusión se asoció con un aumento en la tasa de ICP y una reducción de la mortalidad hospitalaria (AU)
Introduction and objectives: To analyze the association between the development of network systems of care for ST-segment elevation myocardial infarction (STEMI) in the autonomous communities (AC) of Spain and the regional rate of percutaneous coronary intervention (PCI) and in-hospital mortality. Methods: From 2003 to 2012, data from the minimum basic data set of the Spanish taxpayer-funded health system were analyzed, including admissions from general hospitals. Diagnoses of STEMI and related procedures were codified by the International Diseases Classification. Discharge episodes (n = 302 471) were distributed in 3 groups: PCI (n = 116 621), thrombolysis (n = 46 720), or no reperfusion (n = 139 130). Results: Crude mortality throughout the evaluation period was higher for the no-PCI or thrombolysis group (17.3%) than for PCI (4.8%) and thrombolysis (8.6%) (P < .001). For the aggregate of all communities, the PCI rate increased (21.6% in 2003 vs 54.5% in 2012; P < .001) with a decrease in risk-standardized mortality rates (10.2% in 2003; 6.8% in 2012; P < .001). Significant differences were observed in the PCI rate across the AC. The development of network systems was associated with a 50% increase in the PCI rate (P < .001) and a 14% decrease in risk-standardized mortality rates (P < .001). Conclusions: From 2003 to 2012, the PCI rate in STEMI substantially increased in Spain. The development of network systems was associated with an increase in the PCI rate and a decrease in in-hospital mortality (AU)

INTRODUCCIÓN Y OBJETIVOS: La información sobre la seguridad de la duración de la estancia es escasa en el infarto de miocardio con elevación del segmento ST no complicado. Se han estudiado las tendencias y la seguridad en España de la estancia corta (≤ 3 días) frente a la prolongada. MÉTODOS: Se identificaron en el Conjunto Mínimo Básico de Datos los episodios de pacientes con infarto de miocardio con elevación del segmento ST no complicado tratados con intervención coronaria percutánea primaria y dados de alta vivos entre 2003 y 2015. La estancia media se ajustó mediante regresión de Poisson multinivel con efectos mixtos. El efecto de la estancia corta en el reingreso por causa cardiovascular a 30 días se evaluó en episodios de 2012-2014 mediante emparejamiento por puntuaciones de propensión y regresión logística multinivel, comparando las razones estandarizadas de reingreso y mortalidad por riesgo. RESULTADOS: La estancia ajustada disminuyó significativamente (razón de tasas de incidencia <1; p <0,001) cada año desde 2003. La estancia corta no fue un predictor independiente de reingreso (OR=1,10; IC95%, 0,92-1,32) ni de mortalidad (OR=1,94; IC95%, 0,93-14,03). Después del emparejamiento, tampoco hubo diferencias significativas en ambos casos (OR=1,26; IC95%, 0,98-1,62; y OR=1,50; IC95%, 0,48-5,13). Las comparaciones entre las razones estandarizadas de reingreso y mortalidad por riesgo confirmaron estos resultados, excepto en la de mortalidad a los 30 días, significativamente mayor en la estancia corta, aunque probablemente sin significado clínico (el 0,103 y el 0,109%; p <0,001). CONCLUSIONES: La estancia ≤ 3 días aumentó significativamente en España desde 2003 a 2015 y parece una opción segura en el infarto de miocardio con elevación del segmento ST no complicado
INTRODUCTION AND OBJECTIVES: There are few data on the safety of length of stay in uncomplicated ST-segment elevation myocardial infarction. We studied trends in hospital stay and the safety of short (≤ 3 days) vs long hospital stay in Spain. METHODS: Using data from the Minimum Basic Data Set, we identified patients with uncomplicated ST-segment elevation myocardial infarction who underwent primary percutaneous coronary intervention and who were discharged alive between 2003 and 2015. The mean length of stay was adjusted by multilevel Poisson regression with mixed effects. The effect of short length of stay on 30-day readmission for cardiac diseases was evaluated in episodes from 2012 to 2014 by propensity score matching and multilevel logistic regression. We also compared risk-standardized readmissions for cardiac diseases and mortality rates. RESULTS: The adjusted length of stay decreased significantly (incidence rate ratio <1; P <.001) for each year after 2003. Short length of stay was not an independent predictor of 30-day readmission (OR, 1.10; 95%CI, 0.92-1.32) or mortality (OR, 1.94; 95%CI, 0.93-14.03). After propensity score matching, no significant differences were observed between short and long hospital stay (OR, 1.26; 95%CI, 0.98-1.62; and OR, 1.50; 95%CI, 0.48-5.13), respectively. These results were confirmed by comparisons between risk-standardized readmissions for cardiac disease and mortality rates, except for the 30-day mortality rate, which was significantly higher, although probably without clinical significance, in short hospital stays (0.103% vs 0.109%; P <.001). CONCLUSIONS: In Spain, hospital stay ≤ 3 days significantly increased from 2003 to 2015 and seems a safe option in patients with uncomplicated ST-segment elevation myocardial infarction

INTRODUCCIÓN Y OBJETIVOS: Analizar la asociación entre volumen y resultados en cirugía de revascularización aortocoronaria (CABG) en el Sistema Nacional de Salud de España. MÉTODOS: Se analizaron los eventos de CABG entre 2013-2015. Las variables de resultado seleccionadas fueron la mortalidad hospitalaria en el evento índice, así como los reingresos por causa cardiaca a los 30 días y la mortalidad en el reingreso. Mediante regresión logística multinivel, se obtuvieron las tasas ajustadas a riesgo de mortalidad hospitalaria (RAMER) y de reingresos (RARER). Se discriminó entre centros de alto y bajo volumen mediante un análisis no condicionado (k-medias), utilizando también para CABG la recomendación de volumen de las guías de práctica clínica. RESULTADOS: Se incluyeron 17.335 eventos de CABG con una mortalidad bruta del 5,0%. Los eventos atendidos en centros de bajo volumen para CABG (< 155 CABG al año) mostraron una RAMER un 17% superior (5,81%±2,07 frente a 4,96%±1,76; p <0,001) y una correlación lineal negativa entre volumen y RARER (r=-0,318; p = 0,029), así como una mayor proporción de complicaciones durante el evento. La misma asociación entre volumen y mejores resultados se encontró en la CABG aislada. CONCLUSIONES: Los hospitales del Sistema Nacional de Salud tienen un bajo volumen promedio de CABG. Se ha hallado una asociación entre mayor volumen y mejores resultados en la CABG total y aislada. Los hallazgos de este estudio aconsejan una mayor concentración de CABG y la publicación de los resultados ajustados a riesgo de la intervención coronaria
INTRODUCTION AND OBJECTIVES: To analyze the association between volume and outcomes in coronary artery bypass grafting (CABG) in the Spanish National Health System. METHODS: We analyzed CABG episodes from 2013 to 2015. The selected outcome variables were in-hospital mortality in the index episode, 30-day cardiac-related readmissions, and mortality during readmission. Risk-adjusted rates of in-hospital mortality (RAMER) and 30-day readmissions (RARER) were calculated using multilevel logistic regression. High- and low-volume hospitals for CABG were identified by a nonconditioned analysis (k-means) and by compliance with the volume recommendation of clinical practice guidelines. RESULTS: A total of 17 335 CABG index episodes were included, with a crude in-hospital mortality rate of 5.0%. Episodes attended in low-volume centers for CABG (< 155 CABG per year) showed 17% higher RAMR (5.81%±2.07 vs 4.96±1.76; P <.001) and a negative linear correlation between volume and RARR (r=−0.318; P=.029), as well as a higher percentage of complications during the episode. The same association between volume and more favorable outcomes was found in isolated CABG. CONCLUSIONS: The mean CABG volume is low in Spanish National Health System hospitals. Higher volume was associated with better outcomes in CABG, both total and isolated. The findings of this study indicate the need for a higher concentration of CABG programs, as well as the publication of risk-adjusted outcomes of coronary intervention
