Trombolisis intravenosa en accidente cerebro vascular isquémico agudo en un hospital público de Chile: análisis prospectivo de 54 casos / Intravenous thrombolysis for ischemic stroke: experience in 54 patients

Background: Intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) reduces disability in patients with ischemic stroke. However, its implementation in Chilean public general hospitals has been slow and faces some difficulties. Aim: To analyze the results of an intravenous thrombolysis protocol implementation in a public general hospital. Material and Methods: During a lapse of 28 months a standardized protocol for intravenous thrombolysis implemented in the emergency room of a public hospital, was prospectively evaluated. Fifty four patients with ischemic stroke were treated and assessed three months later as outpatients. Results: At three months of follow-up, 66.4% of patients subjected to thrombolysis had a favorable evolution, defined as having 0 to 1 points in the modified Rankin scale. Intracerebral hemorrhage rate was 11.1%, including 5.5% of symptomatic intracerebral hemorrhage. Four percent of patients had systemic bleeding complications after thrombolysis. The mortality rate was 14.8%. Conclusions: The success rates, mortality, and complications rate were comparable to the results obtained in international studies, despite of the absence of a stroke unit to manage stroke and its complications.

Impacto de Ia telemedicina en Ia calidad del control de tratamiento anticoagulante oral / Impact of tele-medicine for control of oral anticoagulant treatment

Antecedentes: En el año 2014 se inició Telemedicina desde el Policlinico de Tratamiento Anticoagulante oral del Hospital San Juan de Dios y el Hospital de Curacaví, evitando así el traslado de pacientes a Santiago para el control con el médico especialista. Métodos: Se utilizó licencia de video conferencia en el Hospital San Juan de Dios, dispositivo móvil, equipo de INR capilar y stock de Acenocumarol en el Hospital de Curacaví. Resultados: En total se han realizado 2.174 consultas vía Telemedicina (junio 2014 a diciembre 2015). Esta estrategia ha sido bien evaluada por los pacientes. La mejora en la calidad del tratamiento ha sido evidente: 58,3% de los pacientes del Hospital de Curacaví se encuentran en rango terapéutico, superior al 50,8% de los pacientes del Hospital San Juan de Dios (p < 0,05). En cuanto al Tiempo en Rango Terapéutico (TTR) 50,6% de los pacientes del Hospital de Curacaví se encuentran en rango versus 46,2% de los pacientes del Hospital San Juan de Dios (p< 0,05). Conclusiones: La Telemedicina utilizada por equipos comprometidos es capaz de mantener indicadores de calidad de la atención que la validan como herramienta de atención clínica a distancia. La Telemedicina, en cuanto es una herramienta que acerca el especialista a comunidades alejadas de centros hospitalarios complejos, es valorada y muy bien calificada por los usuarios.

Background: Starting in 2014 telemedicine has been used to control oral anticoagulant treatment (OAT) in patients attending a peripheral hospital (Curacaví), in connection with Hospital San Juan de Dios, based in Santiago. Methods: A license for video conference was available to communicate both hospitals. Capillary INR and medications were available at Curacaví Hospital. Results: Between June 2014 and December 2015, 2174 indications for OAT have been made through tele-medicine. Different estimates of quality of care and user satisfaction have been rated > 6.7 (1-7 scale). Percent of INR measurements in therapeutic range was 58.3% in Curacavi and 50.8% at Hospital San Juan de Dios (p<0.05) and time in therapeutic range was 50.6% vs 42.6%, respectively (p<0.05) Conclusion: Tele-medicine allowed a close relationship between remote medical facilities and a complex medical center and was fully validated as a means of controlling OAT with a high degree of acceptance by patients.
