The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) is a tool used to assess disease activity in Ankylosing Spondylitis (AS) patients.
  • It evaluates symptoms such as pain, stiffness, fatigue, and discomfort experienced by the patient.
  • The BASDAI score is a numerical value that indicates the severity of disease activity in AS patients.
  • A higher BASDAI score suggests more active disease and greater symptom burden.
  • Healthcare professionals use the BASDAI score to guide treatment decisions and monitor the effectiveness of interventions over time.
Formula

BASDAI Score Formula

The BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) score is calculated using the following formula:
BASDAI = (Q1 + Q2 + Q3 + Q4 + Q5 + 2 * Q6) / 5
where:
  • Q1 refers to the score of the first question related to fatigue.
  • Q2 refers to the score of the second question related to spinal pain.
  • Q3 refers to the score of the third question related to joint pain and swelling.
  • Q4 refers to the score of the fourth question related to areas of localized tenderness.
  • Q5 refers to the score of the fifth question related to the severity of morning stiffness.
