    Curriculum reform at the Pontificia Universidad Catolica de Chile School of Medicine
    (SOC MEDICA SANTIAGO, 2016) Cisternas, Marcela; Rivera, Solange; Sirhan, Marisol; Thone, Natalie; Valdesa, Claudia; Pertuze, Julio; Puschel, Klaus
    The career of Medicine at the Pontificia Universidad Catolica de Chile was established from the beginning (1929), with a classical Flexner curriculum design. In seven years, the career is divided in three cycles: basic sciences, clinics and internship. It obtained Chilean accreditation and fulfilled American Association of Medical Colleges accreditation requirements. Changes in the Chilean epidemiological profile and health system, and new teaching methods in medicine, stimulated a process of deep curricular analysis, identifying strengths and weaknesses of the medical career. The curricular strengths were well-developed scientific and clinical components, fully committed students and faculties, well defined learning objectives and excellent clinical campuses. Curricular weaknesses included a poor vertical and horizontal integration, few student centered methodologies and a weak emphasis concerning doctor's professionalism. Subsequently, the whole community of teachers, students and medical educators worked on the design of a new curriculum, establishing a new graduate profile and designed it oriented by learning objectives, of six years of duration, with an optimized course sequence that melds basic science and clinical concepts, with strong emphasis on humanities and professionalism. It prioritizes an early contact with patients from the first year and expands teaching methods. The main objective of this process was to achieve a new curriculum with an integrative structure. This was implemented in 2015 with an approved protocol to evaluate the outcomes.

    The long-term stability of portable spirometers used in a multinational study of the prevalence of chronic obstructive pulmonary disease
    (DAEDALUS ENTERPRISES INC, 2006) Perez Padilla, Rogelio; Vazquez Garcia, Juan Carlos; Nelly Marquez, Maria; Roberto B Jardim, Jose; Pertuze, Julio; Lisboa, Carmen; Muino, Adriana; Victorina Lopez, Maria; Talamo, Carlos; Montes de Oca, Maria; Valdivia, Gonzalo; Maria B Menezes, Ana; PLATINO Team
    BACKGROUND: We report the performance of an ultrasound-based portable spirometer (EasyOne) used in a population-based survey of the prevalence of chronic obstructive pulmonary disease, conducted in 5 Latin American cities: Sao Paulo, Brazil; Mexico City, Mexico; Montevideo, Uruguay; Santiago, Chile; and Caracas, Venezuela (the Latin American COPD Prevalence Study [PLATINO]). METHODS: During the survey period (which ranged from 3 months to 6 months in the various locations) we collected daily calibration data from the 70 EasyOne spirometers used in the 5 survey cities. The calibrations were conducted with a 3-L syringe, and the calibration data were stored in the spirometer's database. RESULTS: Ninety-seven percent of the calibration volumes were within +/- 64 mL (2.1%) of the 3-L calibration signal. Excluding data from the first city studied (Sao Paulo), where one calibration syringe had to be replaced, 98% of the calibration checks were within +/- 50 mL (1.7%). The measured volume was affected only minimally by the syringe's peak flow or emptying time. CONCLUSION: In these 70 EasyOne spirometers neither calibration nor linearity changed during the study. Such calibration stability is a valuable feature in spirometry surveys and in the clinical setting.
