Decrypting the Improving Access to Psychological Therapies (IAPT) Code

IAPT communications have an agenda, their focus is on persuading their source of revenue, local Clinical Commissioning Groups (CCGs) to expand funding, to cover staffing costs of £0.5billion by 2024.  To achieve this goal it uses language that is familiar to the GPs that comprise CCGs, ‘NICE compliant’, ‘recovery’ and claiming a comparability of outcome to those in randomised controlled trials. But CCG’s are themselves under orders from NHS England, who have never critically appraised IAPT’s claims.

The secret to breaking the IAPT Code, is strangely its’ use of the ICD-10 code (the World Health Organisation’s labelling system for all disorders). The recent IAPT Manual (August 2021) recommends that IAPT clinicians give at least one code to each client, to characterise their debility. But nowhere in the Manual does it suggest that IAPT clinicians make a diagnosis. An ICD-10 code is only as reliable as the diagnosis made. The Manual claims that NICE Guidelines are based on ICD-10 codes and that IAPT is therefore NICE compliant.  However the treatments recommended by NICE are all diagnosis specific, it follows that if there is no diagnosis there can be no fidelity to a NICE protocol. A key part of IAPT’s code is to gloss over that IAPT’s interventions are based, not on diagnosis but on ‘problem descriptors’. The silent assumptions are that:

a) there would be reliable agreement (reliability) between clinicians about what would constitute a clients main problem and

b) there is a body of evidence that a problem descriptor acts as a key to unlock the door to a specific protocol. Further that the specific protocol has been demonstrated to confer an added value, over and above an active placebo, for the chosen problem descriptor. There is an assumption of clinical utility.

But there is no empirical evidence for either a) the reliability or b) the clinical utility. 

IAPT operates its’ own coding device, akin to the Enigma machine used by the Germans in World War 2, and it has as a result ill-served millions. NHS England and CCG’s have totally failed to recognise its’ operation, believing instead IAPT’s public broadcasts e.g a 50% recovery rate, when independent assessment indicates a 10% recovery rate Scott (2018)
