Outcomes

Outcomes in IAPT are measured in terms of three measures:

  • recovery,
  • reliable improvement,
  • and reliable recovery.

Recovery

Recovery in IAPT is measured in terms of ‘caseness’ – a term which means a referral has severe enough symptoms of anxiety or depression to be regarded as a clinical case. A referral has moved to recovery if they were defined as a clinical case at the start of their treatment (‘at caseness’) and not as a clinical case at the end of their treatment, measured by scores from questionnaires tailored to their specific condition.

The Government target is that 50% of eligible referrals to IAPT services should move to recovery.4

51.6% of eligible referrals moved to recovery

Calculating Recovery rates

In December 2020, the calculation to calculate the recovery rate is performed as below:

 

Count_Recovery / (Count_FinishedCourseTreatment - Count_NotAtCaseness) * 100

 

23,291 / ( 48,111 - 2,957) * 100 = 51.6%

Sub-national recovery rates are published in the Monthly Activity Data File as column ‘Percentage_Recovery’.


Reliable improvement

A referral has shown reliable improvement if there is a significant improvement in their condition following a course of treatment, measured by the difference between their first and last scores on questionnaires tailored to their specific condition.

67.7% of referrals finishing a course of treatment showed reliable improvement

Calculating improvement rates

In December 2020, the calculation is performed as below:

 

Count_Improvement / Count_FinishedCourseTreatment *100

 

32,597 / 48,331 * 100 = 67.4%

 

Sub-national reliable improvement rates are published in the Monthly Activity Data File as column ‘Percentage_Improvement’.


Reliable recovery

A referral has reliably recovered if they meet the criteria for both the recovery and reliable improvement measures. That is, they have moved from being a clinical case at the start of treatment to not being a clinical case at the end of treatment, and there has also been a significant improvement in their condition.

48.8% of referrals reliably recovered

Calculating reliable recovery rates

In December 2020, this calculation is performed as follows:

 

Count_ReliableRecovery / (Count_FinishedCourseTreatment - Count_NotAtCaseness) * 100

 

22,301 / (48,111 - 2957) * 100 = 47.2%

Sub-national reliable recovery rates are published in the Monthly Activity Data File as column ‘Percentage_ReliableRecovery’.


The chart below compares recovery, reliable improvement, and reliable recovery rates across a period of twelve months.


Each quarter, more detailed data are published about recovery, reliable improvement and reliable recovery. The most recent quarterly data, Quarter 3 2020/21, can be found at: http://digital.nhs.uk/pubs/iaptdec20
