In 2020 at a regional hospital in Japan, a woman had her spinal nerves severed during a hip surgery. It was later revealed that the doctor in charge had been involved in eight cases of medical incidents in eight months — a so-called "repeater" doctor.

We take a look at the current medical situation and ask experts how to better ensure the safety of patients.
