Findings from a newly published study are likely to silence those who suggest doctors need to return to wearing white coats to improve patient respect.

According to US researchers, patient perception in terms of a doctor’s capability, trustworthiness and reliability is not affected by the presence of visible tattoos and non-traditional piercings (on the doctor not the patient).

“Physician tattoos and facial piercings were not factors in patients’ evaluations of physician competence, professionalism or approachability,” the study authors said.
