Psychology of Injury, Pain, Anxiety and Depression

Precious Time Lost

Time LostTime Lost: The elimination of all physical causes for a complaint and only then considering the psychological causes is referred to as diagnosis-by-exclusion.

We are taught diagnosis-by-inclusion, to examine psychological causation with the same vigor as physical diagnosis, but we rarely do so.

If a patient has complaints that are not readily verified, there are three choices:

a. Assume the patient is malingering
b. Assume other factors are forcing the patient to somatize (emphasize minor physical complaints/sensations)
c. Assume that more or repeated diagnostic studies should be ordered

The concept of diagnosis-by-exclusion is when we fail to consider the patient’s role in the complaints and look exclusively for physical causation. We do not look at the psychosocial variables until we have excluded every possible, even obscure, physical causes regardless of how improbable.

Case managers may not consider the impact of other variables (marriage, drugs, crime, financial problems, depression, boredom, personality, etc etc) which are giving rise to the physical complaints and, consequently, to lost time until the patient makes consideration of such issues unavoidable. Since the patient most often lacks insight, the patient will continue to submit to repeatedly nonproductive diagnostic tests rather than deal with the true underlying reason they do not wish to return to work.

Once the pattern of diagnosis-by-exclusion has become the problem solving approach of an individual clinician or a company, it is quite difficult to change, and a great deal of time and nonproductive expense is lost.
