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

Calculating Recovery rates

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

Count_Recovery / (Count_FinishedCourseTreatment - Count_NotAtCaseness) * 100

25,361 / ( 53,722 - 3,364  ) * 100 = 50.4%

 

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.

Calculating Improvement rates

In September 2020, the calculation is performed as below:

Count_Improvement / Count_FinishedCourseTreatment *100 

36,201 / 53,722 * 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.

Calculating reliable recovery rates

In September 2020, this calculation is performed as follows:

Count_ReliableRecovery / (Count_FinishedCourseTreatment - Count_NotAtCaseness) * 100

24,108 / (53,722 - 3,364) * 100 = 47.9%

 

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.

Consistently, a higher proportion show reliable improvement than move to recovery; this is because reliable improvement only looks at the scale of change, and not whether the referral has moved below the clinical caseness threshold.

Reliable recovery, which requires both recovery and reliable improvement, is the most stringent measure and therefore has the lowest rate.

Each quarter, more detailed data are published about recovery, reliable improvement and reliable recovery. The most recent quarterly data, Quarter 1 2020/21, can be found at: http://digital.nhs.uk/pubs/iaptjun20.
