Petitie

tegen het gebruik van

de Reeves-kriteria

in wetenschappelijk onderzoek

 

(initiatief Tom Kindlon)

 

 

 

 


 

Tom Kindlon is initiatiefnemer van een petitie tegen het toepassen van de "ge- operationaliseerde Fukuda-kriteria" ook wel Reeves-kriteria (klik hier) genoemd.

 

De CVS-1994-kriteria, die mede dankzij de "biopsychosociale inbreng"

al zodanig vaag opgerekt zijn dat ze niets meer zeggen ("vergaarbakdiagnose"),

worden op voorstel van dr. Reeves van het CDC nog verder "geabstraheerd".

Dit alles staat volledig haaks op de gewenste aanscherping van diagnosekriteria.

 

In tegenstelling tot de kontraproduktieve naamswijzigingscampagne (klik hier),

is dit een initiatief dat ik ME/CVS-patiŽnten van harte wil aanbevelen.

Het zou zelfs beter zijn de Canadese kriteria (of soortgelijke kriteria) aan te bevelen.

CDC CFS research should not involve the empirical definition (2005)

 

 

We call on the Centers for Disease Control and Prevention (CDC) to stop using the "empirical" definition [1] (also known as the Reeves 2005 definition) to define Chronic Fatigue Syndrome (CFS) patients in CFS research.

 

The CDC claim it is simply a way of operationalizing the Fukuda (1994) definition [2]. However the prevalence rates suggest otherwise: the "empirical" definition gives a prevalence rate of 2.54% of the adult population [3] compared to 0.235% (95% confidence interval, 0.142%-0.327%) and 0.422% (95% confidence interval, 0.29%-0.56%) when the Fukuda definition was used in previous population studies in the US [4,5].

 

The definition lacks specificity. For example, one research study [6] found that 38% of those with a diagnosis of a Major Depressive Disorder were misclassified as having CFS using the empirical/Reeves definition.

Brief comment from Tom Kindlon:

 

I have Chronic Fatigue Syndrome (CFS) for over 20 years.

 

I want a lot of research progress in my lifetime and believe the empirical definition (2005) (also known as the Reeves definition (2005)) decreases the chances that this will occur: abnormalities that would show up using a more strictly defined definition won't show up using the empirical/Reeves defini≠tion; and abnormalities that might show up in the broad group covered by the empirical/Reeves definition are not necessarily representative of CFS patients.

 

Similarly treatments that might work on a more strictly defined group of patients might not show up using the very broad empirical/Reeves definition and treatments that might appear to work overall on the group defined using the empirical/Reeves definition might not be suitable for people who satisfy a stricter definition. This messes up the CFS literature even further.
