I often think about my partner's pregnancy journey, when she was pregnant she was given a folder which had all sorts of forms in. For every appointment she went to, she'd bring the folder in and the staff would read the existing pages, and add their own (results of scans etc...)

Due to some minor complications, her book ended up being quite full, and we went to lots of places, some hospitals, some GPs (which are private companies), and they could all read and add to this book.

In the UK, you can rock up to any hospital with maternity facilities when you're in labour, and have your baby there. You bring your folder with you, and they can read the notes from previous doctors. Once the baby is born, you hand the notes in, and they are collated together and put on your NHS record.

I often think about making a digital version of that. How difficult it'd be to build something that worked across all the systems that different healthcare providers use, is reliable, and secure.

Sometimes, analog is best.
