In Japan, Mr Katsumura Hisashi lost his first child during childbirth when his wife was given a labour-inducing drug without being informed of the details of her treatment. At that time, hospitals were not obligated to inform patients of the details of treatment, and there were no clear pathways for consent and understanding between patients and medical professionals. Since then, he has become an advocate for patient participation and patient-centred medicine and has succeeded in getting laws amended to require disclosure of medical information to patients.
