The recommendations of GET and CBT were abandoned in the Dutch and
Belgian guidelines (respectively 2018 and October 2020). The former caution that patients who refuse to undergo GET or CBT should not be penalized in receiving healthcare.
The statement about the Dutch guidelines is not quite right. What was published in 2018 was the Dutch Health Council advice for the Dutch parliament, not a guideline.
The statements about GET and CBT in the document have lots of nuances.
The Health Council saw 'no reason' to recommend GET.
Regarding CBT, it states that there is no evidence for its efficacy in house- or bedbound patients. Still, a majority of the Health Council committee believes that a subgroup of non-housebound patients can benefit from CBT. The committee believes that reports of adverse effects from CBT can be explained by the fact that ME/CFS has a variable course, combined with the fact that CBT is not always effective - this could lead patients to attribute a deterioration
during CBT
to CBT, in the absence of a causal relationship.
The Health Council accepts the possibility, in individual cases, of 'damage' from CBT. It advises health professionals to be alert to this and to advise the patient to stop increasing their physical activity 'if this happens'. (Several Dutch patient advocates have noted that this advice is completely at odds with - and can hardly be implemented in the context of - the Dutch treatment protocol 'CBT for CFS' by Knoop and Bleijenberg, which would instead encourage the therapist to offer alternative interpretations/cognitions regarding the increase in symptoms.)
The passage regarding 'not penalizing' patients for refusing GET or CBT or both is about assessment of patients by insurance doctors. Dutch law requires employees to cooperate with 'treatments that are considered adequate according to general medical standards'. The Health Council advice states that neither GET nor CBT should be seen as adequate treatments for ME/CFS in this sense.
This conclusion was embraced by the leadership of UWV (the Dutch DWP), but not by the Dutch Association for Insurance Medicine (NVVG) - which in effect means that insurance doctors at UWV still force employers into CBT.
New treatment guidelines are currently being written. They will be based on the new NICE guidelines. Since the creation of the new Dutch guidelines is underway, it seems they will be based on the NICE draft. I do not know what influence the revised guideline text that will be published by NICE in august might still have on the Dutch guidelines.
There are separate guidelines for insurance doctors, though. I am not aware of plans to replace those as well.
Long story short: so far, the Netherlands have not ditched the BPS approach or CBT from any of their guidelines, though to be consistent with the Health Council advice of 2018, the new guidelines would certainly need to ditch GET. They would also need to ditch CBT at least for those house- or bedbound. But hey, let's hope the new guidelines will follow the NICE draft and go much further than that.
