We are concerned that this letter seems to be part of an attempt to stop discussion about the Lightning Process. We suggest Dr Vallings and her supporters look at the actual evidence such as the very well-conducted trial by the Bristol Clinical Trials Unit which found a benefit for teenagers with Chronic Fatigue Syndrome (CFS) from the Lightning Process in 2017.
1 The cost-effectiveness of the Lightning Process was UK pounds 1474 per QALY (2017 currency). Dr Vallings’ preferred Pacing Therapy is the least cost-effective at UK pounds 127 047 in 2013 UK pounds.
2 CBT is UK pound 18 374 and graded exercise 55 235. This would suggest that Pacing is a modestly effective treatment that is expensive.
The NICE guidelines are quoted for the safety/harm of the Lightning Process. The claimed harms come from a qualitative study (not a cohort) where possibly two people claimed they were harmed (there were no harms in the Bristol Study). Clearly, something bizarre happened at the NICE Guideline on CFS as four people resigned, prompting a group of Scandinavian Psychologists to write an article in the Lancet saying that there was ideological capture of the Guideline group.
