The appropriate way to address a doctor can vary depending on cultural norms, the doctor's preference, and the context of the interaction. In many formal and professional settings, it's customary to address a doctor using their title and last name, such as "Dr. Smith" or "Dr. Johnson." This practice shows respect for their professional expertise and training.
However, there has been a shift towards more informal and patient-centered communication in some healthcare settings. Some doctors may introduce themselves by their first name to create a more friendly and approachable atmosphere, especially when interacting with patients or colleagues they know well. In these cases, addressing the doctor by their first name would be appropriate.
To avoid any misunderstandings, it's a good idea to pay attention to how the doctor introduces themselves or how they sign their name on their emails or correspondence. If they use their first name, it's generally acceptable to follow suit and address them by their first name. If they introduce themselves using their title and last name, it's best to use that more formal address until they suggest otherwise.
When in doubt, using their title and last name is usually a safe and respectful option. If you feel uncertain about the doctor's preference, you can also politely ask how they would like to be addressed, showing that you want to be respectful of their preferences.
