Este trabajo pretende, por un lado, describir y analizar los resultados de la primera medición nacional de la carga de trabajo académico de estudiantes de instituciones del Consejo de Rectores de las Universidades Chilenas (CRUCH), en un conjunto seleccionado de carreras. En segundo término, presentar el Sistema de Créditos Transferibles, que se ha denominado SCT-Chile, acordado por este Consejo a fines de agosto de 2006.

El presente artículo analiza el modelo de financiamiento utilizado por el Ministerio de Educación de Chile. Este modelo considera mecanismos que incentivan la implementación o mejoramiento del desempeño estratégico de las instituciones, así como el eficaz empleo de unidades de análisis institucional, tanto para efectos del desarrollo de programas y proyectos, como para la gestión institucional y la alimentación del

Background The purpose of this study is to determine if patients with osteoarthritis that undergo hip or knee arthroplasty jeopardize their life expectancy in Chile. Methods A survival analysis study was designed and approved by our institutional ethics review board. Patients were included if they underwent surgery for hip or knee osteoarthritis and were 50 years or older at the time of surgery. Patients were excluded if arthroplasty was performed for fracture, hemophilia arthropathy, or tumor. A multiparametric Weibull regression was estimated, and the hazard ratio was reported. For internal validity, a bootstrap of 200 repetitions was performed. Results A total of 4 094 arthroplasties were included. The Kaplan-Meier curve estimates a higher survival than the general population up to 12 years, after which the median survival is less than the general population. The bootstrap multiparametric Weibull regression estimated a hazard ratio of 1.53 (95% confidence interval: 1.27 to 1.84) for women, 1.09 (1.08 to 1.10) for every year older, and 1.29 (1.07 to 1.53) for hip arthroplasty patients. Conclusion Mortality after hip and knee arthroplasty in Chile follows a bimodal behavior similar to reports from the United States and Europe. At first, mortality is lower than the general population but worsens after 12 to 15 years of surgery
