Basdai

From WikiMD's Wellness Encyclopedia

BASDAI (Bath Ankylosing Spondylitis Disease Activity Index) is a diagnostic tool used to determine the disease activity in patients with ankylosing spondylitis (AS). It is a self-administered questionnaire that helps in assessing the effectiveness of treatments and the progression of the disease.

Overview[edit | edit source]

The BASDAI was developed by rheumatologists at the Royal National Hospital for Rheumatic Diseases in Bath, United Kingdom. It is widely used in both clinical practice and research settings to evaluate the severity of symptoms in patients with ankylosing spondylitis.

Components[edit | edit source]

The BASDAI consists of six questions that measure the following symptoms over the past week:

  1. Fatigue
  2. Spinal pain
  3. Joint pain/swelling
  4. Areas of localized tenderness (also known as enthesitis)
  5. Morning stiffness duration
  6. Morning stiffness severity

Each question is scored on a scale from 0 (no problem) to 10 (worst problem). The final BASDAI score is calculated by averaging the scores of the first five questions and adding the score of the sixth question, then dividing by five.

Scoring and Interpretation[edit | edit source]

A BASDAI score of 4 or higher is generally considered indicative of active disease, which may necessitate a change in treatment. The score helps healthcare providers to make informed decisions regarding the management of ankylosing spondylitis, including the use of nonsteroidal anti-inflammatory drugs (NSAIDs), biologic therapy, and physical therapy.

Clinical Use[edit | edit source]

The BASDAI is used in conjunction with other diagnostic tools such as the Bath Ankylosing Spondylitis Functional Index (BASFI) and imaging studies like magnetic resonance imaging (MRI) to provide a comprehensive assessment of disease activity and functional impairment in patients with ankylosing spondylitis.
