title: [Introduction of virtual patients to clinical case portfolios for undergraduate medical students].
abstract: BACKGROUND
  In 2007, a Clinical-Case-Portfolio (CCP) was introduced as a new assessment instrument for fourth grade undergraduate medical students. Since then, several changes have been implemented such as reduction on the number of clinical cases, peer review and the introduction of virtual patient to the portfolio.
  
  
  OBJECTIVE
  To describe the virtual patient model incorporated to the CCP and assess the perception of this change and its effects on the performance of undergraduate students.
  
  
  METHODS
  Virtual patients were implemented based on prototype clinical cases with specific syndromes. Students perceptions about CCP before and after the introduction of virtual patients were evaluated using a validated questionnaire that was answered voluntarily and anonymously.
  
  
  RESULTS
  Overall perception of CCP significantly improved after the incorporation of virtual patients (97.1 ± 24.9 and 111.3 ± 25.7 points; 57.8 and 66.2% respectively). The same improvements were observed for the domains Student Learning, Organization and Evaluation, Teaching Methodology and Integration. In both years, students obtained high grades in CCP evaluations. However CCP grades were not significantly correlated with integrated final grades.
  
  
  CONCLUSIONS
  The incorporation of virtual patients improved undergraduate students perception of CCP.
