Guernsey States decided the healthcare system should provide a comparable range of services to the NHS in 2020.
Around a third of NICE-approved medical procedures at the time were only accessible locally if patients paid for them privately.

We'd also like to know if patients have been refused access to a new treatment, he added, so we can identify any areas where such access is still restricted.
