Oxford Research Criteria for Post Infectious Fatigue Syndrome (PIFS)

Purpose: To evaluate a patient with chronic fatigue using the Oxford research criteria for the post-infectious fatigue syndrome (PIFS).

Description

Consensus criteria for the diagnosis of chronic fatigue following an infection were proposed at a conference at Oxford University in 1990. Post-infectious fatigue syndrome is a subset of the chronic fatigue syndrome that has a definite link to a preceding infection.


 

Criteria - all of the following:

(1) all of the Oxford research criteria for the chronic fatigue syndrome (see 22.04.03, above)

(2) There is definite evidence of an infection at onset or presentation.

(3) The fatigue syndrome is present for minimum of 6 months after the onset of the infection.

(4) The infection has been corroborated by laboratory evidence.

 

where:

• A self-report of an infection by the patient may not be sufficiently reliable to constitute definite evidence of an infection.
