Informed consent: a global perspective.

Our aim in this paper was to investigate the guidelines and laws governing informed consent in the English-speaking world. We noted a recent divergence from medical paternalism within the United Kingdom, highlighted by the Montgomery v Lanarkshire Health Board ruling of 2015. We investigated the situation in the United Kingdom, Australia, New Zealand, Canada, and the United States of America. We read the national guidance regarding obtaining consent for surgical intervention for each country. We used the references from this guidance to identify the laws that helped inform the guidance, and reviewed the court documents for each case. There has been a trend towards a more patient-focused approach in consent in each country. Surgeons should be aware of the guidance and legal cases so that they can inform patients fully, and prevent legal problems if outdated practices are followed.
