Update to methodology in measures ASD01g, ASD01i and their corresponding percentages
An issue in the methodology originally published was identified post-publication in the referral to care contact component of the publication. This related to the cut off date used for a referral to have been discharged from service without a diagnosis or care contact or for a referral to still be waiting for a diagnosis or care contact.
The cut off date used originally for these measures was the end date of each reporting quarter, it has now been changed to the end of the final full quarter of performance data available.
An updated data file is provided below, suffixed with v2.
