But Cartwright had wider impacts beyond just the impact on the cervical screening programme, and I think it's worth going into those further as well—not just in New Zealand, actually, around the world. I entered medical school a decade after the Cartwright inquiry precipitated a range of improvements in our health system. The Health and Disability Commissioner framework was set up in response to that, and that's the cornerstone of our patient rights practice in New Zealand. Our health ethics committees make sure we didn't have the same problems with research without consent—informed consent practice improved in both research and clinical settings. I was very lucky as a medical student to be lectured on these changes by Professor Charlotte Paul. Charlotte's teaching on these issues was informed by her first-hand involvement in the Cartwright inquiry as an expert adviser. And she also brought to that a deep knowledge of the complexities of screening and a moral clarity on the harm done to those women and the changes we needed to make to ensure that that never happened again.
