Cost modifications during the early years of the use of the national cardiovascular data registry for quality improvement

OBJECTIVES: Quality improvement (QI) initiatives based on data from international registries have been reported previously; however, there is a lack of information on the impact on the costs of medical care associated with the use of these tools. METHODS: Patients admitted due to myocardial infarction (MI), included in the ACTION Registry® and CathPCI Registry®, in a private Brazilian hospital (i.e., the reference hospital) were analyzed. The costs of care of these patients were compared to the costs of MI admissions in nine similar hospitals not included in the same QI program. Regression models were used to analyze the cost change over time between the two groups of hospitals. Readmission rates were compared using logistic regression, adjusting for the same variables as in the cost model. RESULTS: Overall, the annual medical cost inflation in Brazil was higher than the annual cost trend in the reference hospital during the period of analysis. Moreover, the annual in-hospital costs indicate that the reference hospital has a statistically significant 6% lower cost trend for patients with acute MI, compared to patients with the same diagnostic code in the comparison hospitals group, in an adjusted analysis (p-value=0.041). Using multivariable analysis, the readmission rates were also found to be significantly lower in the reference hospital than in the comparison hospitals, with an odds ratio of 0.68 (p-value=0.042). CONCLUSION: The use of the NCDR® as a benchmark to guide QI programs outside the United States was associated with the positive impact of bending the cost curve to below that of national medical inflation and the comparison hospitals' costs, with a lower incidence of hospital readmission.

Mortality reduction with use of oral beta-blockers in patients with acute coronary syndrome

OBJECTIVES: Recent studies have revealed a relationship between beta-blocker use and worse prognosis in acute coronary syndrome, mainly due to a higher incidence of cardiogenic shock. However, the relevance of this relationship in the reperfusion era is unknown. The aim of this study was to analyze the outcomes of patients with acute coronary syndrome that started oral beta-blockers within the first 24 hours of hospital admission (group I) compared to patients who did not use oral beta-blockers in this timeframe (group II). METHODS: This was an observational, retrospective and multicentric study with 2,553 patients (2,212 in group I and 341 in group II). Data regarding demographic characteristics, coronary treatment and medication use in the hospital were obtained. The primary endpoint was in-hospital all-cause mortality. The groups were compared by ANOVA and the chi-square test. Multivariate analysis was conducted by logistic regression and results were considered significant when p<0.05. RESULTS: Significant differences were observed between the groups in the use of angiotensin-converting enzyme inhibitors, enoxaparin, and statins; creatinine levels; ejection fraction; tabagism; age; and previous coronary artery bypass graft. Significant differences were also observed between the groups in mortality (2.67% vs 9.09%, OR=0.35, p=0.02) and major adverse cardiovascular events (11% vs 29.5%, OR=4.55, p=0.02). CONCLUSIONS: Patients with acute coronary syndrome who underwent early intervention with oral beta-blockers during the first 24 hours of hospital admission had a lower in-hospital death rate and experienced fewer major adverse cardiovascular events with no increase in cardiogenic shock or sustained ventricular arrhythmias compared to patients who did not receive oral beta-blockers within this timeframe.

Fondaparinux versus Enoxaparin - Which is the Best Anticoagulant for Acute Coronary Syndrome? - Brazilian Registry Data / Fondaparinux versus Enoxaparina - Qual o Melhor Anticoagulante para Síndrome Coronariana Aguda? - Dados de um Registro Brasileiro

Abstract Background: Recent studies have shown fondaparinux's superiority over enoxaparin in patients with non-ST elevation acute coronary syndrome (ACS), especially in relation to bleeding reduction. The description of this finding in a Brazilian registry has not yet been documented. Objective: To compare fondaparinux versus enoxaparin in in-hospital prognosis of non-ST elevation ACS. Methods: Multicenter retrospective observational study. A total of 2,282 patients were included (335 in the fondaparinux group, and 1,947 in the enoxaparin group) between May 2010 and May 2015. Demographic, medication intake and chosen coronary treatment data were obtained. Primary outcome was mortality from all causes. Secondary outcome was combined events (cardiogenic shock, reinfarction, death, stroke and bleeding). Comparison between the groups were done through Chi-Square test and T test. Multivariate analysis was done through logistic regression, with significance values defined as p < 0.05. Results: With regards to treatment, we observed the performance of a percutaneous coronary intervention in 40.2% in the fondaparinux group, and in 35.1% in the enoxaparin group (p = 0.13). In the multivariate analysis, we observed significant differences between fondaparinux and enoxaparin groups in relation to combined events (13.8% vs. 22%. OR = 2.93, p = 0.007) and bleeding (2.3% vs. 5.2%, OR = 4.55, p = 0.037), respectively. Conclusion: Similarly to recently published data in international literature, fondaparinux proved superior to enoxaparin for the Brazilian population, with significant reduction of combined events and bleeding.

Resumo Fundamento: Estudos recentes têm apresentado superioridade do fondaparinux em relação à enoxaparina em pacientes com síndrome coronariana aguda (SCA) sem supradesnivelamento de ST, principalmente relacionada à redução de sangramentos. A descrição desse achado em registro brasileiro ainda não foi documentada. Objetivo: Comparar fondaparinux versus enoxaparina no prognóstico intrahospitalar em SCA sem supradesnivelamento de ST. Métodos: Estudo retrospectivo, multicêntrico e observacional. Foram incluídos 2.282 pacientes (335 no grupo fondaparinux e 1.947 no grupo enoxaparina) entre maio de 2.010 e maio de 2.015. Foram obtidos dados demográficos, medicações utilizadas e tratamento coronariano adotado. O desfecho primário foi mortalidade por todas as causas. O desfecho secundário foi eventos combinados (choque cardiogênico, reinfarto, morte, acidente vascular cerebral e sangramentos). A comparação entre os grupos foi realizada por meio de Q-quadrado e teste-T. A análise multivariada foi realizada por regressão logística, sendo considerado significativo p < 0,05. Resultados: Em relação ao tratamento, observou-se realização de intervenção coronária percutânea em 40,2% no grupo fondaparinux e 35,1% no grupo enoxaparina (p = 0,13). Na análise multivariada, observaram-se diferenças significativas entre os grupos fondaparinux e enoxaparina em relação a eventos combinados (13,8% vs. 22%, OR = 2,93, p = 0,007) e sangramentos (2,3% vs. 5,2%, OR = 4,55, p = 0,037), respectivamente. Conclusão: Semelhante aos dados recentemente publicados na literatura mundial, fondaparinux mostrou-se superior à enoxaparina para a população brasileira, com redução significativa de eventos combinados e sangramentos.

Improving Indicators in a Brazilian Hospital Through Quality-Improvement Programs Based on STS Database Reports

ABSTRACT OBJECTIVE: To report the initial changes after quality-improvement programs based on STS-database in a Brazilian hospital. METHODS: Since 2011 a Brazilian hospital has joined STS-Database and in 2012 multifaceted actions based on STS reports were implemented aiming reductions in the time of mechanical ventilation and in the intensive care stay and also improvements in evidence-based perioperative therapies among patients who underwent coronary artery bypass graft surgeries. RESULTS: All the 947 patients submitted to coronary artery bypass graft surgeries from July 2011 to June 2014 were analyzed and there was an improvement in all the three target endpoints after the implementation of the quality-improvement program but the reduction in time on mechanical ventilation was not statistically significant after adjusting for prognostic characteristics. CONCLUSION: The initial experience with STS registry in a Brazilian hospital was associated with improvement in most of targeted quality-indicators.

Impacto inicial de uma clínica de insuficiência cardíaca em hospital cardiológico privado / Initial impact of a disease management program on heart failure in a private cardiology hospital

Fundamentos: A insuficiência cardíaca ainda leva a hospitalizações frequentes apesar dos notáveis avanços terapêuticos. Programas que monitoram e otimizam cuidados têm potencial para melhorar o controle desses pacientes apesar de evidências ainda controversas quanto ao seu real benefício. Objetivos: Caracterizar a população incluída em clínica de insuficiência cardíaca e avaliar a hipótese de benefícios a curto prazo (seis meses). Métodos: Estudo prospectivo que avaliou pacientes hospitalizados com insuficiência cardíaca em hospital privado cardiológico de janeiro a dezembro 2012. Os pacientes foram estratificados em: Grupo 1 – pacientes pré-Programa de cuidados (feito apenas registro de dados); Grupo 2 – pacientes pós-Programa (registro dos mesmos dados junto com intervenções educativas feitas pelo programa de cuidados da Clínica de Insuficiência Cardíaca). Analisadas características da população, indicadores de qualidade e desfechos clínicos. Resultados: Avaliados 762 pacientes, média de idade 70,4±11,0 anos, 56,0 % do sexo masculino. Fração de ejeção reduzida observada em 65,0 %, perfil hemodinâmico B em 66,0 %, etiologia isquêmica em 52,0 % e infecção como fator de descompensação em 29,0 % dos casos. Desfechos analisados nos Grupos 1 e 2, respectivamente: re-hospitalização em 30 dias (13,0 % vs. 9,0 %; p=0,10); tempo médio de hospitalização (9,0 dias vs. 8,4 dias; p=0,4); descompensação por má aderência (17,0 % vs. 10,0 %; p=0,004); mortalidade hospitalar (9,0 % vs. 8,0 %; p=0,7).

Background: Heart failure still leads to frequent hospitalizations despite notable therapeutic advances. Programs that monitor and optimize care have the potential to enhance control of these patients, although evidence of their real benefits is still controversial. Objectives: To describe the population with heart failure included in a Clinical Care Program, assessing the hypothesis of short-term benefits (6 months). Methods: Prospective study assessing heart failure patients in a private cardiology hospital from January to December 2012, divided into two groups: Group 1 – pre-Care Program patients with only data recorded; Group 2 – post-Care Program patients with the same data recorded, together with educational interventions through the Care Program run by the Heart Failure Clinic. The demographic characteristics of the population were analyzed, together with quality indicators and clinical outcomes. Results: Among the 762 patients assessed, the mean age was 70.4±11.0 years, with 56.0% male. Reduced ejection fraction was noted in 65.0%, hemodynamic profile B in 66.0%, ischemic etiology in 52.0% and infection as a decompensation factor in 29.0% of cases. The outcomes analyzed in Groups 1 and 2 were, respectively: hospital readmissions within 30 days (13.0% vs. 9.0%; p=0.1); average length of stay (9.0 days vs. 8.4 days, p=0.4); decompensation due to poor compliance (17.0% vs. 10.0%; p=0.004); and in-hospital mortality (9.0% vs. 8.0%; p=0.7).

Implantação de protocolo institucional para o uso racional de hemoderivados e seu impacto no pós-operatório de cirurgias de revascularização miocárdica / Implementation of an institutional protocol for rational use of blood products and its impact on postoperative of coronary artery bypass graft surgery

OBJETIVO: Cirurgias cardíacas são, por vezes, acompanhadas de perdas sanguíneas significativas, e transfusões de sangue podem ser necessárias. No entanto, o uso indiscriminado de hemoderivados pode resultar em efeitos danosos para o paciente. Neste estudo, avaliamos os efeitos imediatos da implantação de um protocolo para o uso racional de hemoderivados no perioperatório de cirurgias de revascularização miocárdica. MÉTODOS: Entre os meses de abril e junho de 2011, foi implementado um protocolo institucional em um hospital privado especializado em cardiologia com a anuência e a colaboração de sete equipes de cirurgia cardíaca, visando ao uso racional de hemoderivados. Foram verificados dados clínicos e demográficos dos pacientes, e avaliados o uso de hemoderivados e os desfechos clínicos no período intra-hospitalar, antes e após a implantação do protocolo. O protocolo consistiu em uma campanha institucional junto às equipes cirúrgicas, de anestesiologia e intensivistas, para difundir a prática do uso de hemoderivados com base em critérios clínicos objetivos (anemia com repercussões hemodinâmicas e disfunção ventricular significativa), bem como tornar rotineira a prescrição de ácido epsilon-aminocaproico no intraoperatório, que é prática recomendada por diretrizes internacionais baseadas em evidência científica. RESULTADOS: Após os 3 meses de implantação do protocolo, houve aumento do uso de ácido epsilon-aminocaproico de 31% para 100%. Antes da implantação do protocolo, 67% das cirurgias utilizaram alguma transfusão sanguínea; após a implantação, 40% das cirurgias necessitaram de alguma transfusão sanguínea nos meses subsequentes do mesmo ano (p<0,001). Não houve diferença significativa nos desfechos clínicos avaliados antes e após implantação do protocolo. CONCLUSÃO: O uso racional de hemoderivados, associado à infusão do ácido epsilon-aminocaproico, tem o potencial de reduzir o número de hemotransfusões no perioperatório de cirurgias cardíacas...

OBJECTIVE: Cardiac surgeries are sometimes followed by significant blood loss, and blood transfusions may be necessary. However, indiscriminant use of blood components can result in detrimental effects for the patient. We evaluated the short-term effects of implementation of a protocol for the rational use of blood products in the perioperative period of cardiac surgery. METHODS: Between April and June 2011, an institutional protocol was implemented in a private hospital specializing in cardiology to encourage rational use of blood products, with the consent and collaboration of seven cardiac surgery teams. We collected clinical and demographic data on the patients. The use of blood products and clinical outcomes were analyzed during hospital stay before and after protocol implementation. The protocol consisted of an institutional campaign with an educational intervention to surgical and anesthesiology teams; the goal was to tailor blood transfusion practice according to clinical goals (anemia with hemodynamic changes and significant ventricular dysfunction) and to make routine the prescription of å-aminocaproic acid intraoperatively, which is recommended by international guidelines based on scientific evidence. RESULTS: After three months of protocol implementation, the use of å-aminocaproic acid increased from 31% to 100%. A total of 67% of surgeries before protocol implementation required any blood transfusion, compared with 40% that required any blood transfusion after protocol implementation in subsequent months of the same year (p<0.001). There was no significant difference in clinical outcomes assessed before and after implementation of the protocol. CONCLUSION: The rational use of blood products associated with infusion of å-aminocaproic acid has the potential to reduce the number of blood transfusions in perioperative of cardiac surgeries, but it can affect the risk of complications.
