Background: Pediatrics ethics education should enhance medical students' skills to deal with ethical problems that may arise in the different settings of care. This study aimed to analyze the ethical problems experienced by physicians who have medical education and pediatric care responsibilities, and if those problems are associated to their workplace, medical specialty and area of clinical practice. Methods: A self-applied semi-structured questionnaire was answered by 88 physicians with teaching and pediatric care responsibilities. Content analysis was performed to analyze the (...) qualitative data. Poisson regression was used to explore the association of the categories of ethical problems reported with workplace and professional specialty and activity. Results: 210 ethical problems were reported, grouped into five areas: physician-patient relationship, end-of-life care, health professional conducts, socioeconomic issues and health policies, and pediatric teaching. Doctors who worked in hospitals as well as general and subspecialist pediatricians reported fewer ethical problems related to socioeconomic issues and health policies than those who worked in Basic Health Units and who were family doctors. Conclusions: Some ethical problems are specific to certain settings: those related to end-of-life care are more frequent in the hospital settings and those associated with socioeconomic issues and public health policies are more frequent in Basic Health Units. Other problems are present in all the setting of pediatric care and learning and include ethical problems related to physician-patient relationship, health professional conducts and the pediatric education process. These findings should be taken into consideration when planning the teaching of ethics in pediatrics.Trial registrationThis research article didn't reports the results of a controlled health care intervention.
