THE DIAGNOSTIC PROCESS

  • Step 1 Identify the patient's chief concern.

  • Step 2 Identify barriers to communication.

  • Step 3 Identify special concerns.

  • Step 4 Create a symptom timeline and sketch the anatomy (if needed).

  • Step 5 Create a diagnostic hypothesis list considering all possible forms of remote and local pathology that could cause the patient's chief concern.

  • Step 6 Sort the diagnostic hypothesis list by epidemiology and specific case characteristics.

  • Step 7 Ask specific questions to rule specific conditions or pathological categories less likely.

  • Step 8 Re-sort the diagnostic hypothesis list based on the patient's responses to specific questioning.

  • Step 9 Perform tests to differentiate among the remaining diagnostic hypotheses.

  • Step 10 Re-sort the diagnostic hypothesis list based on the patient's responses to specific tests.

Case Description

++

Maria is a 6-month-old girl whose parents noticed at 4 months of age that she held her head turned to the side and that her face seemed somewhat asymmetrical. Maria has two older siblings who are healthy and well.

++

  • The chief concern of Maria's parents is her asymmetrical head posture and facial features.

++

STEP #2: Identify barriers to communication.

++

  • Patient's/family's preferred language is different than that of the health care provider. Maria's parents are most comfortable speaking Spanish; therefore, an interpreter is necessary for the verbal part of the differential diagnosis process. It is important to ensure that the discriminating questions and answers are accurately translated for everyone.

  • Presence of other children in the family. Because the mother has had two children who are healthy and well, there is a level of experiential wisdom that also needs to be considered when questioning this ...
