RESUMO
Introducción: La optimización de recursos en un servicio terciario tiene un impacto en la salud a nivel nacional, lo que otorga interés en conocer posibles formas de disminuir estos costos. Por lo tanto, al momento de solicitar un examen, se debe considerar los beneficios y limitaciones diagnósticas, valorando su aporte en la toma de decisiones médicas. Objetivos: Determinar el porcentaje de informes de ecografías no retiradas y la gravedad de los diagnósticos señalados en estos. Materiales y Métodos: Se evaluaron 794 informes no retirados en 4 años, consignando la gravedad de 12 patologías de interés, se excluyeron los informes incompletos y ecocardiografías transesofágicas, dando un total de 751 ecocardiogramas transtorácicos, los datos fueron evaluados mediante el sistema SPSS. Resultados: Los ecocardiogramas no retirados en 4 años correspondieron al 5,6%, de estos un 40,6% resultaron normales y 59,4% presentaron alguna anormalidad, siendo severas en el 14,4% y patologías de riesgo vital en un 13,0%. Conclusiones: En este trabajo no se hallaron datos suficientes para justificar la realización de 40,6% de los exámenes analizados. La existencia de patologías severas y de riesgo vital en los ecocardiogramas no retirados, destaca la importancia del seguimiento de los exámenes realizados por un hospital terciario, ya que puede afectar el pronóstico de los pacientes.
Background: Resource optimization in a tertiary service has an impact on a national health level, giving interested in knowing ways to reduce these costs. Therefore, when applying for an exam, it should be consider the benefits and diagnostic limitations, assessing their contribution in the medical decisions. Aim: Determine the percentage of non pick up ecocardiography reports and the severity of those diagnostics. Material y Methods: 794 non pick up reports in 4 years was evaluated, and it was consigning 12 pathologies of interest with severe diagnostics. Incomplete reports and transesophageal echocardiography were excluded, yielding a total of 751 transthoracic echocardiography, data that were processed with SPSS system. Results: The non picked up echocardiography reports in 4 years corresponded to 5.6%, of these, 40.6% were normal and 59.4% had abnormalities, that were severe in 14.4 % and lifethreatening pathologies in 13.0% Conclusions: In this study it was not found sufficient data to justify the realization of 40.6 % of the analyzed tests. The existence of severe and life-threatening diagnostics, remark the importance of follow-up exams in a tertiary hospital.
RESUMO
Background: The optimal dose of Streptokinase in the treatment of acute myocardial infarction is not well established. Apparently, the thrombolytic efficacy would not increase with doses over 750.000 units. Aim: To compare the effectiveness and safety of treatment with low doses of Streptokinase, ranging from 500.000 to 750.000 units, in patients with ST elevation acute myocardial infarction. Patients and methods: From September 1993 to September 1998, the GEMI register of patients with acute myocardial infarction, was carried out in 37 hospitals, incorporating 4,938 patients. Of these, 1,631 patients received streptokinase. According to the administered dose of Streptokinase, patients were divided in two groups: 1,465 patients who received 1.5 millions U in 60 minutes (classical therapy group), and 166 patients with ischemic chest discomfort and either ST-segment elevation or left bundle-branch block on the electrocardiogram, who received 500.000 to 750.000 U streptokinase administered in no more than 30 minutes, with heparin, within 0 to 6 hours of symptom onset. Successful reperfusion, mortality, complications, and hospital outcome was evaluated in both groups. Results: The low dose group of patients had a better reperfusion criteria profile. No differences between groups were observed in patient evolution, mortality, maximum Killip classification, post myocardial infarction heart failure, ischemic complications, arrhythmias or mechanical complications. Conclusions: These results suggest that streptokinase in low doses is at least as effective as classical therapy, in the treatment of ST elevation acute myocardial infarction.
