    La simulación clínica es una herramienta de aprendizaje complementaria a los métodos tradicionales en la práctica clínica. Permite desarrollar habilidades y destrezas en escenarios seguros. La división de ginecología y obstetricia de la Universidad Católica (UC) imparte un curso de emergencias obstétricas para especialistas utilizando esta metodología. Presentamos la evaluación de los especialistas que realizaron el curso en el año 2016. Materiales y métodos: se realizó un curso de simulación de escenarios de emergencia en obstetricia, con un total de 16 horas separadas en 2 días. Con simuladores de alta y mediana complejidad. Tutoriados por instructores acreditados por el Institute of medical simulation de la Universidad de Harvard. Al finalizar el curso los participantes respondieron una encuesta escrita de diversos tópicos del curso. Resultados: participaron 93 especialistas. 76% de los participantes estuvo completamente de acuerdo y 23% de acuerdo con que la práctica con modelos simulados mejora la destreza relacionada con la realización de los procedimientos propuestos en el curso. El 100% de ellos indica que recibió retroalimentación considerada como útil durante las sesiones de entrenamiento y consideran que están completamente de acuerdo o de acuerdo con que esta metodología les permite cometer errores en forma segura. Conclusiones: la implementación de la metodología de simulación clínica en la docencia de emergencias obstétricas es muy bien evaluada por los especialistas, ya que entrega retroalimentación académica útil de cada caso y les permite cometer errores sin riesgos para los pacientes con un alto nivel de realismo.

    HPV16/18 genotyping for the triage of HPV positive women in primary cervical cancer screening in Chile
    (2015) Lagos Lucero, Marcela; Van De Wyngard, Vanessa; Poggi, Helena; Cook, María Paz; Viviani García, Paola; Barriga Cosmelli, María Isabel; Ferreccio Readi, Catterina; Pruyas, Martha; Lagos Lucero, Marcela; Van De Wyngard, Vanessa; Poggi, Helena; Cook, María Paz; Viviani, Paola; Barriga, María I.; Ferreccio Readi, Catterina; Pruyas, Martha
    Abstract Background We previously conducted a population-based screening trial of high-risk human papillomavirus (hrHPV) testing and conventional cytology, demonstrating higher sensitivity (92.7 % vs 22.1 % for CIN2+) but lower positive predictive value (10.5 % vs 23.9 %) of hrHPV testing. Here we report the performance of HPV16/18 genotyping to triage the hrHPV positive participants. Methods Women aged 25 years and older received hrHPV (Hybrid Capture 2) and Papanicolaou testing; positives by either test underwent colposcopy and directed biopsy, as did a sample of double-negatives. hrHPV positive women were reflex-tested with HPV16/18 genotyping (Digene HPV Genotyping PS Test). Results Among the 8,265 participants, 10.7 % were hrHPV positive, 1.7 % had ASCUS+ cytology, 1.2 % had CIN2+; 776 (88 %) hrHPV positive women had complete results, of whom 38.8 % were positive for HPV16 (24.0 %), HPV18 (9.7 %) or both (5.1 %). CIN2+ prevalence in HPV16/18 positive women (16.3 %, 95 % CI 12.3-20.9) was twice that of HPV16/18 negative women (8.0 %, 95 % CI 5.7-10.8). HPV16/18 genotyping identified 40.5 % of CIN2, 66.7 % of CIN3 and 75.0 % of cancers. Compared to hrHPV screening alone, HPV16/18 triage significantly reduced the referral rate (10.7 % vs 3.7 %) and the number of colposcopies required to detect one CIN2+ (9 vs 6). When HPV16/18 negative women with baseline ASCUS+ cytology were also colposcopied, an additional 14 % of CIN2+ was identified; referral increased slightly to 4.2 %. Conclusions HPV16/18 triage effectively stratified hrHPV positive women by their risk of high-grade lesions. HPV16/18 positive women must be referred immediately; referral could be deferred in HPV16/18 negative women given the slower progression of non-HPV16/18 lesions, however, they will require active follow-up.Abstract Background We previously conducted a population-based screening trial of high-risk human papillomavirus (hrHPV) testing and conventional cytology, demonstrating higher sensitivity (92.7 % vs 22.1 % for CIN2+) but lower positive predictive value (10.5 % vs 23.9 %) of hrHPV testing.
