Clinical-care protocol for preventing mediastinitis after coronary artery bypass graft surgery: A quality improvement initiative from a private hospital.

BACKGROUND: Surgical site infections after cardiac surgery are associated with severe outcomes, including reoperation and death. We aimed to describe the effect of a standardized clinical-care protocol for preventing mediastinitis in patients who underwent coronary artery bypass graft surgery (CABG). METHODS: In a hospital certified by Joint Commission International, all patients who underwent CABG from January 2011 to December 2016 were compared in two periods according to the moment of implementation of a standardized clinical-care protocol for prevention of mediastinitis (CCPPM): pre-protocol (January 2011-December 2012) and post-protocol (January 2013-December 2016). The CCPPM consisted of the patient using a kit containing chlorhexidine 2% for bathing, mupirocin 20 mg/g for nasal topical use and chlorhexidine 0.12% for oral hygiene for 5 days before surgery, in addition to prophylaxis with a glycopeptide antimicrobial and strict glucose control (110-140 mg/dL) during surgery and immediate postoperative. RESULTS: We evaluated 1760 patients who underwent CABG in both periods. The occurrence of mediastinitis before protocol implementation was 1.44% (10 of 692 CABG). After the implementation of the protocol, there was an important reduction in the incidence of mediastinitis to 0.09% (1 of 1068 CABG) (P = 0.002). Although we did not observe a significant difference in mortality between the groups (2.3% vs 1%, P = 0.77), there was fewer in-hospital mortality due to mediastinitis after the CCPPM (0.2% vs 0%, P < 0.001). CONCLUSION: Implementation of a standardized CCPPM was associated with a significant reduction in the incidence of mediastinitis after CABG and reduction of mortality in the group of patients with mediastinitis.

Chest Pain Network with Support of Telemedicine: Impact on Reperfusion Therapy and Clinical Outcomes After 8 Years of Experience.

Background: Different approaches of evaluation by cardiologists using telemedicine have the potential of improving care of patients with ST elevation myocardial infarction (STEMI). Objective: To compare the use of pharmacoinvasive strategy and associated clinical outcomes (heart failure [HF] and mortality) among patients with STEMI before and after a program of telemedicine and also according to the level of support by telemedicine. Methods: A chest pain network with the support of a cardiologist through telemedicine was implemented in 2012 in 22 emergency departments without a local cardiac catheterization laboratory. Initially (phase 1 of telemedicine), the decision to discuss the case with the cardiologist was based on the judgment of the emergency physician. At the end of 2018, the use of telemedicine was modified and a dedicated cardiologist was available continuously to discuss systematically all suspected cases (phase 2 of telemedicine). The use of fibrinolytics and the rates of HF and in-hospital mortality were compared among three different periods: pretelemedicine (2011), and phase 1 and phase 2 of the telemedicine program. Results: We evaluated 1034 STEMI patients and after comparing the three phases, we did not find significant differences regarding age, gender, and comorbidities. The use of fibrinolytics before transferring STEMI patients to a percutaneous coronary intervention center (pharmacoinvasive strategy) increased after telemedicine implementation (38% vs. 65.2%; p < 0.01), which was associated with a lower rate of HF (23.9% vs. 14.4%; p = 0.01) and death (7.9% vs. 4.0%; p = 0.05). The in-hospital mortality was lower in phase 2 with systematic evaluation by telemedicine compared with pretelemedicine (7.9% vs. 3.3%; p = 0.04). Conclusion: The implementation of a systematic and organized chest pain protocol, including telemedicine support, was associated with a significant increase in the use of pharmacoinvasive strategy and better clinical patient outcomes in patients with STEMI. Our findings provide important insights on how to improve the management of this high-risk population, reducing the gap between evidence and clinical practice.

Clinical outcomes and need for intensive care after non-ST-segment-elevation myocardial infarction.

BACKGROUND: The decision on whether non-ST-segment elevation myocardial infarction (NSTEMI) patients should be admitted to intensive care units (ICU) takes into account several factors including hospital routines. The Acute Coronary Treatment and Intervention Outcomes Network (ACTION) ICU score was developed to predict complications requiring ICU care post-NSTEMI. METHODS: We described patient characteristics and clinical outcomes of 1263 NSTEMI patients admitted to a private hospital in Sao Paulo, Brazil, from 2014 to 2018. We also aimed to retrospectively identify NSTEMI patients who might not have needed to be admitted to the ICU based on the ACTION ICU risk score. We defined complications requiring ICU care post-NSTEMI as cardiac arrest, cardiogenic shock, stroke, re-infarction, death, heart block requiring pacemaker placement, respiratory failure, or sepsis. RESULTS: Mean age was 62.3 years and 35.8% were female. A total of 94.6% of NSTEMI patients were admitted to the ICU. Most NSTEMI patients (91.9%) underwent coronary angiography. Percutaneous coronary intervention was performed in 47.1% and coronary artery bypass graft surgery in 10.3%. Complications requiring ICU care occurred in 62 patients (4.9%). In-hospital mortality rate was 1.3%. Overall, 70.4% had an ACTION ICU score ≤ 5. The C-statistics for the ACTION risk score to predict complications was 0.55 (95% confidence interval 0.47-0.63). CONCLUSIONS: Complications requiring ICU care were infrequent in a cohort of NSTEMI patients who were routinely admitted to the ICU over a 4-year period. The ACTION risk score had low accuracy in the prediction of complications requiring ICU care in our population.

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...
