This study aims to evaluate the impact of the search for internet health information by patients on the doctor-patient relationship and satisfaction of both physicians and patients. In total, 200 patients of a tertiary hospital in Brazil and a convenience sample of 92 physicians were included. The questionnaires applied consisted of statements concerning the study's objective; answers were given on a 5-point Likert scale. We conducted a descriptive analysis and used nonparametric tests to verify statistical differences in perception between subgroups of interest. In this study, 85.6% of internet users searched for internet health information but were skeptical about the information they found. They were mostly positive about the doctor-patient relationship; however, they desired greater engagement in health decisions. Overall, physicians tended to have a slightly positive view about internet health information impact on patients' health despite some possible harmful effects. However, they believe that search for internet health information causes unnecessary fear and concern in patients, reduces doctor's work efficiency, and that internet health information is not accurate or reliable. The massive search for internet health information has led to significant changes in the doctor-patient communication model. Both parties have demands to be addressed: patients need more reliable information; and physicians must adapt to these changes in a way that neither diminishes their autonomy as healthcare providers nor worsens the doctor-patient relationship. Hopefully, physicians could play a central role in educating patients and indicating adequate sources of information.
