BACKGROUND : Specialist training is based on the gradual acquisition of expertise, skills and responsibilities. The aim of this study is to determine the opinion of residents regarding their training. METHODS : This was a cross-sectional descriptive study based on an online survey of 5th-year residents during February and March 2017. RESULTS : A total of 194 residents (62.8% of the total) responded to the survey, 62.9% of whom were women and 50% of whom were younger than 30years, representing hospitals from all levels and from the 17 autonomous communities. More than 80% of the residents choose the specialty once again and believed that the duration of the residence was appropriate; however, 76.3% would eliminate some of their rotations. Most of the residents did not know the objectives of each rotation, and 37.1% felt they were not adequately supervised. Some 82.5% would change the evaluation system, and 68.0% would favour performing an excellence test. Most of the residents had published at least one article or performed one presentation at a congress; however, only 27.8% had completed a doctoral thesis. Although 74.7% of the internists believed they would find employment, only 28.4% had an offer 1month after completing their residence. CONCLUSIONS : The residents are satisfied with their training, although there is still a deficit in supervision and dissatisfaction with the method of assessing their knowledge and the precarious job market during the first year for specialists.
