Monthly Time Series for Key Measures

An issue has been identified in the CCG data for April and May 2021. This is a result of the recent CCG mergers, which came into effect in April 2021. Some providers have submitted activity under the old (pre-April 2021) CCG codes, and this activity has been mapped to ‘unknown CCG code’, instead of the correct new CCG code.

This is being reviewed and corrected data will be published when it is available.

Please note the timeseries data in this publication was updated on 07 March 2022 to include revised data, for some providers, for the period September 2020 to May 2021. The core data for July 2021 is unaffected. This is following a one-off resubmission exercise that took place in August 2021 and covered the data period September 2020 to May 2021 inclusive.

Waiting Times

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.

92.3% of referrals waited less than 6 weeks to enter treatment

Calculating Waiting Times

In July 2021, this calculation is performed as follows: 

(Count_FirstTreatment6WeeksFinishedCourseTreatment / Count_FinishedCourseTreatment) * 100

(54,148 / 58,655) * 100 = 92.3%

Sub-national waiting times rates are published in the Monthly Activity Data File as columns ‘Percentage_FirstTreatment6WeeksFinishedCourseTreatment’ and ‘Percentage_FirstTreatment18WeeksFinishedCourseTreatment’.

The chart below shows that, nationally, waiting times measures have consistently been above the target, particularly the proportion seen within 6 weeks.
