Rating system provided to the public via a website called NHS choices, which allowed patients to directly review GPs, dentists, hospitals, and other providers by leaving written feedback and a score of one to five stars. Between 2013 and the end of 2019, the website provided a summary star rating for each provider, measured as the rolling average score over the past two years, rounded to the nearest half star. This rounding creates a series of sharp discontinuities. For example, a provider with an index value of 3.76 will appear with 4 stars, while a provider with an index value of 3.74 will appear with 3.5 stars.
