Improvement in quality indicators using NCDR® registries: First international experience.

BACKGROUND: The National Cardiovascular Data Registry (NCDR®) Database is commonly used for quality-improvement initiatives in North America, but little is known about the application of this tool in other regions of the world. METHODS: All consecutive patients admitted due to myocardial infarction (MI) and/or undergoing percutaneous coronary intervention (PCI) from January 2012 until December 2015 in a Brazilian private cardiovascular hospital were included respectively in ACTION REGISTRY®-GWTG™ and CathPCI Registry®. Meetings including all hospital staff were performed quarterly to discuss every NCDR® report. Quality improvement initiatives were developed based on the reports which were also used for evaluation of changes after the interventions. The following indicators were considered a priority 1) Door-to-ECG and door-to-balloon (D2B) times; 2) PCI appropriateness; 3) length of stay; 4) delivery of guideline-based medication. Changes in the quality of care with respect to the over time were assessed using linear and logistic regression for continuous and binary outcomes, respectively. RESULTS: A total of 1.382 patients were included in the ACTION REGISTRY®-GWTG™ and 3.179 patients in the CathPCI Registry®. In the ACTION registry, the overall AMI performance composite of quality indicators improved along the 4 years from 95.0% to 99.6% (p for trend <0.001). The percentage of appropriate/uncertain PCI in acute and elective scenario increased along the years from 91.1% and 70.9% to 96.6% and 84.7%, respectively (p for trend <0.001). CONCLUSION: The present novel experience using the NCDR® registries as benchmarks to guide quality-improvement programs in an international site was associated with improvement in quality indicators.

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.

Segurança e preditores de sucesso da alta hospitalar no mesmo dia apósintervenção coronária percutânea eletiva / Safety and predictors of same day discharge after elective percutaneous coronary intervention

Apesar de a alta hospitalar no mesmo dia (AHMD) após intervenção coronária percutânea(ICP) eletiva não complicada ser adotada mundialmente, ela permanece pouco estudada em nosso meio.Objetivamos, assim, avaliar nossa experiência inicial com a AHMD após ICP eletiva, em relação à suas egurança e aos preditores de sucesso. Métodos: Foram incluídos 161 pacientes consecutivos para AHMD, de único centro, selecionados em ambulatório especializado. Para a identificação dos fatores associados ao sucesso da AHMD, foram ajustados modelos de regressão logística simples e múltipla. Resultados: A AHMD foi realizada com sucesso em 114 pacientes (70,8%), tendo os 47 pacientes restantes permanecido internados (45 com alta na manhã seguinte e 2 pacientes após 2 dias). Nenhum paciente com AHMD apresentou evento cardíaco adverso maior ou complicação vascular importante aos 30 dias e no seguimento mediano de 12 meses. No grupo internação, ocorreu apenas um caso de infarto agudo do miocárdio por oclusão de ramo lateral e dois hematomas > 5 cm relacionados ao sítio de punção. Os preditores de sucesso da AHMD foram: via de acesso radial (OR = 5,92; IC95% 1,73-20,21; p = 0,005), presença de lesões tipo A/B1 (OR = 14,09; IC95% 1,70-116,49; p = 0,01) e volume de contraste (OR = 0,76;IC95% 0,65-0,88; p < 0,001). Conclusões: A AHMD foi segura e pôde ser realizada com sucesso na maioria dos pacientes selecionados para ICP eletiva, sendo seus preditores de sucesso o acesso radial, as lesões menos complexas e um volume menor de contraste...

Background: Although same-day discharge (SDD) after elective uncomplicated percutaneous coronary intervention (PCI) be adopted worldwide, it remains poorly studied in our country. We aim to evaluate our initial experience with SDD after elective PCI, regarding its safety and predictors of success. Methods: A hundred and sixty-one single-center consecutive patients, selected in a specialized out patient clinic, were included for SDD. To identify the factors associated with SDD, single and multiple logistic regression models were adjusted. Results: SDD was successfully performed in 114 patients (70.8%) and the remaining 47 patients remained hospitalized (45 with discharge in the following morning and 2 patients after 2 days). No patient with SDD presented major adverse cardiac events or major vascular complications at 30 days or at a median follow-up of 12 months. In the inpatient group, there was only one case of acute myocardial infarction due to a lateral branch occlusion and two patients with > 5 cm hematoma related to the access site. The SDD predictors were radial access route (OR = 5.92; 95%CI 1.73-20.21; p = 0.005), presence of type A/B1 lesions(OR = 14.09; 95%CI 1.70-116.49%; p = 0.01) and contrast volume (OR = 0.76; 95%CI 0.65-0.88; p < 0.001). Conclusions: SDD was safe and could be successfully performed in most patients selected for elective PCI, and its predictors were the radial access, less complex coronary lesions and a and lower contrast volume...

Evaluation of the Society of Thoracic Surgeons score system for isolated coronary bypass graft surgery in a Brazilian population.

OBJECTIVE: Report the experience with the Society of Thoracic Surgeons scoring system in a Brazilian population submitted to isolated coronary artery bypass graft surgery. METHODS: Data were collected from January-2010 to December-2011, and analyzed to determine the performance of the Society of Thoracic Surgeons scoring system on the determination of postoperative mortality and morbidity, using the method of the receiver operating characteristic curve as well as the Hosmer-Lemeshow and the Chi-square goodness of fit tests. From the 1083 cardiac surgeries performed during the study period 659 represented coronary artery bypass graft procedures which are included in the present analysis. Mean age was 61.4 years and 77% were men. RESULTS: Goodness of fit tests have shown good calibration indexes both for mortality (X2=6.78, P=0.56) and general morbidity (X2=6.69, P=0.57). Analysis of area under the ROC-curve (AUC) demonstrated a good performance to detect the risk of death (AUC 0.76; P<0.001), renal failure (AUC 0.79; P<0.001), prolonged ventilation (AUC 0.80; P<0.001), reoperation (AUC 0.76; P<0.001) and major morbidity (AUC 0.75; P<0.001) which represents the combination of the assessed postoperative complications. STS scoring system did not present comparable results for short term hospital stay, prolonged length of hospital stay and could not be properly tested for stroke and wound infection. CONCLUSION: Society of Thoracic Surgeons scoring system presented a good calibration and discrimination in our population to predict postoperative mortality and the majority of the harmful events following coronary artery bypass graft surgery. Analysis of larger samples might be needed to further validate the use of the score system in Brazilian populations.

Comparação das vias radial e femoral nas intervenções coronárias percutâneas: resultados do registro TotalCor / Comparison of radial vs. femoral access in percutaneous coronary interventions: outcomes of the TotalCor registry

Introdução: A intervenção coronária percutânea (ICP) por via radial ainda é pouco utilizada em nosso meio. O objetivo do presente estudo foi avaliar a prevalência e os resultados da ICP por via radial, comparada à via femoral, em uma população do mundo real. Métodos: Registro unicêntrico, com 507 pacientes consecutivos submetidos a ICP pelas vias radial (n = 121) e femoral (n = 386), de acordo com a escolha do operador. Resultados: Os pacientes que utilizaram a via radial (23,9%) eram mais frequentemente do sexo masculino (78,5% vs. 69,9%; P = 0,07) e tabagistas (19,8% vs. 11,7%; P = 0,02), com maior prevalência de lesões uniarteriais (59,5% vs. 46,4%), tipo A/B1 (39% vs. 28,4%) e com função ventricular preservada (87,1% vs. 73%; P < 0,01). Nesse grupo foram utilizados stents de maior diâmetro e menor comprimento. O sucesso do procedimento foi elevado (97,3% vs. 96,3%; P = 0,56) e a incidência de óbito foi baixa, não diferindo entre os grupos (0,8% vs. 0,8%; P = 0,96), assim como as taxas de infarto do miocárdio (2,5% vs. 2,1%; P = 0,73). Não ocorreram revascularizações do vaso-alvo de urgência. Os pacientes tratados pela via radial permaneceram menos tempo internados (1 dia vs. 2 dias; P = 0,02) e não apresentaram complicações vasculares (0 vs. 3,4%; P = 0,045). Conclusões: A utilização da ICP por via radial representa o dobro da média nacional na instituição em que o estudo foi realizado, e a escolha de pacientes para essa técnica trouxe resultados do procedimento equivalentes aos da via femoral, nenhuma complicação vascular, e reduziu à metade o tempo de internação hospitalar.

BACKGROUND: In our country radial access is still underused in percutaneous coronary interventions (PCI). The objective of this study was to evaluate the prevalence and compare radial to femoral vascular access for PCI in a real-world population. METHODS: Single center registry, with 507 consecutive patients undergoing PCI by radial (n = 121) and femoral (n = 386) access, according to the operator's choice. RESULTS: Patients using radial access (23.9%) were more often male (78.5% vs. 69.9%; P = 0.07) and smokers (19.8% vs. 11.7%; P = 0.02), had a higher prevalence of single-vessel disease (59.5% vs. 46.4%), type A/B1 (39% vs. 28.4%) lesions and had preserved ventricular function (87.1% vs. 73%; P < 0.01). Larger diameter and shorter stents were used in this group. Procedure success was high (97.3% vs. 96.3%; P = 0.56), the incidence of death was low and was not different between groups (0.8% vs. 0.8%; P = 0.96), as well as myocardial infarction rates (2.5% vs. 2.1%; P = 0.73). There were no urgent target-vessel revascularizations. Patients treated by the radial approach had a shorter hospitalization period (1 day vs. 2 days; P = 0.02) and did not have vascular complications (0 vs. 3.4%; P = 0.045). CONCLUSIONS: The use of radial access for PCI in our institution is twice the national average and the choice of patients for this technique provided similar results to those obtained by the femoral approach, no vascular complications and halved patients' average stay in hospital.

Taquiarritmia com importante repercussão clínica / Tachyarrhythmia with important clinical repercussions

Na presença de FA com WPW, medicações que aumentam o período refratário do nó AV (como digital ou verapamil) são contra-indicadas porque aumentam a resposta ventricular pela via rápida podendo levar à ?brilação ventricular. Quando há colapso hemodinâmi-co, a cardioversão elétrica é imperativa. O tratamento de?nitivo pode ser obtido pela ablação da via acessória por radiofreqüência.
