The idea

To make a diagnosis, the practitioner depends on what the patient discloses, and patients do not always tell everything. A diagnosis can be wrong in two ways. A false positive says a healthy person is ill. A false negative says an ill person is healthy. A diagnosis should be presented in clear language, with a check that the patient has understood.

In a doctor-centred (directed) consultation, the doctor asks closed questions, decides and instructs. In a patient-centred (sharing) consultation, the doctor asks for the patient’s ideas and worries and agrees a plan with them.

In the key study, Savage and Armstrong (1990) randomly allocated patients of one London GP to a directing or a sharing style. Satisfaction was higher with the directing style.

Rules to remember

Common mistake

Students assume the sharing style won in Savage and Armstrong because it sounds kinder. The directing style gave the higher satisfaction.

Worked example

A blood test for an infection gives a clear result for a man who in fact has the infection. What type of error is this, and what is its main danger?

  1. The test said “no infection”, so the result is negative.
  2. He does have the infection, so the result is false.
  3. A person who is told he is healthy will not be given treatment.

Answer: A false negative; the infection is left untreated and may get worse or spread.
