Which of the following is a disease-related clinical outcome?

• A. Severity of symptoms
• B. Beneficial effects of therapy
• C. Patient satisfaction
• D. Transportation costs

Answer: (A)

The key idea is that a disease-related clinical outcome reflects changes in the patient’s clinical status caused by the disease itself. Severity of symptoms directly measures how much the disease is affecting the patient at a clinical level, capturing the intensity and burden of the disease as it presents. This makes it a clear disease-related clinical outcome.

In contrast, beneficial effects of therapy describe how well a treatment works (a treatment outcome), patient satisfaction measures the patient’s experience and subjective appraisal (a patient-reported outcome), and transportation costs are an economic or service-use metric (not a clinical status change). So the symptom severity best fits the concept of a disease-related clinical outcome.
