One of the stated targets of the IAPT programme is that for referrals finishing a course of treatment in the month, 75% enter treatment within 6 weeks, and 95% within 18 weeks5. These are based on the waiting time between the referral date and the first attended treatment appointment.
In September 2019, this calculation is performed as follows:
43,720 / 50,103 * 100 = 87.3%
Sub-national waiting times rates are published in the Monthly Activity Data File as columns ‘FirstTreatment6WeeksFinishedCourseRate’ and ‘FirstTreatment18WeeksFinishedCourseRate’.
