The Institute of Psychiatry (a WHO Collaborating Centre) is heavily invested in the
Diagnostic and Management Guidelines for Mental Disorders in Primary Care: ICD-10 Chapter V Primary Care Version.
Aka ICD-10 PC; ICD-10 PHC; ICD-10-PHC; the ICD-10 "Primary Care" version of Chapter V.
This is the 1996 WHO non mandatory diagnostic guideline from which the Jenkins group had adapted the UK publication that had required errata slips to be inserted, around 16 years ago.
This diagnostic and management guideline had been the baby of Prof, Sir David Goldberg, now professor emeritus of the Institute of Psychiatry. Published in 1996, it had been aimed at primary care use and for use in low- to middle-income countries; for use in training, education and in low resource settings by often non clinically trained health workers, with no access to psychiatric professionals or where use of the full ICD-10 would not be practical.
It contained just 25 "common mental disorders" and no other disorders or diseases. It wasn't quite the success that Prof, Sir David Goldberg had hoped it would be.
The ICD-10 PHC is currently under revision for ICD-11 PHC.
Once again, Prof, Sir David Goldberg (now 84) has been given the task of overseeing the revision. The work group's Vice-chairs are Michael Klinkman (USA) and WHO's Dr Geoffrey Reed (also USA). Denmark's Marianne Rosendal is also a member of this 12 member working group.
(Klinkman and Rosendal are also members of the ICPC-2 revision committee.)
It is this external work group, known as the
Primary Care Consultation Group (PCCG) that has been proposing, since around 2011, to replace the ICD-10 PHC diagnostic term
F45 Unexplained somatic complaints, with a new proposed construct, "Bodily Stress Syndrome (BSS)."
Since no new progress papers have been published since last year in the name of the PCCG work group and since the full diagnostic guidance texts and the most currently proposed criteria texts are not available for public scrutiny and comment, it is currently unclear whether the group's most recent proposals are for a criteria set adapted from Fink et al (2010) Bodily distress syndrome, based on symptom clusters, or for a simpler criteria set based on symptom count, or for some other flavour of BSS/BDS.
At least one of the field trials for the BSS construct have been part funded by the Institute of Psychiatry.
The PCCG has been operative since around 2010 and has published several progress papers, commentaries, a field trial protocol document and a slide presentation (the slide presentation and other information on BSS was provided to the Countess of Mar in October 2017).
The ICD-11 PHC is planned to include 27 mental health disorders, two of which don't have corresponding disorder categories in the core ICD-11.
For clarity: the construct that is being progressed for the ICD-11 core edition is "Bodily distress disorder (BDD)" - an SSD-like construct, which is differently characterized, has very different criteria (based on excessive psychobehavioral responses, rather than on symptom counts or symptom clusters from body systems) and which captures a different patient set to that captured by the BSS construct.
BDD is the
only construct that has been under consideration for the core ICD-11 edition since it was first entered into the Beta draft in early 2012. It is not the case that WHO/ICD Revision is undecided about which construct it will progress for the core ICD-11 edition.
BDD was also added to SNOMED CT in July 2017 by the SNOMED CT/ICD-11 Mapping Project team as an "exact match" for ICD-11's core BDD concept term.
For those struggling to differentiate between the various ICD editions and publications here is a document that compares their intended purpose, in which countries they are used, and whether they are mandatory for use by WHO Member States or not:
