A working diagnosis indicating the absence of serious disease (such as “calf pain, not DVT”).
The aim of this article is to understand why diagnostic labels are sometimes not applied in general practice consultations and to understand how this approach contributes to making decisions about diagnoses.
Why is a diagnosis sometimes missing?
Bruce Thomas, a general practitioner in Hampshire, UK, pointed out in the 1970s that in up to 40% of patients in general practice no diagnostic label could be attached.1 2 These patients did not require, and generally were not given, specific treatment, and most recovered spontaneously. This remains the case. In a 2005 review of consultation data in the UK, “symptoms, signs and ill-defined conditions” was the computer coded group of disorders presenting most frequently in general practice.3
Also in the 1970s, Howie described “the relative rarity …
