DAPSA Score for Psoriatic Arthritis

Calculates the Disease Activity in PSoriatic Arthritis (DAPSA) score using tender joint count (68 joints), swollen joint count (66 joints), patient global assessment (0–10 VAS), patient pain VAS (0–10), and CRP (mg/dL). Remission ≤4, low ≤14, moderate ≤28, high >28.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the Disease Activity in PSoriatic Arthritis (DAPSA) score using tender joint count (68 joints), swollen joint count (66 joints), patient global assessment (0–10 VAS), patient pain VAS (0–10), and CRP (mg/dL). Remission ≤4, low ≤14, moderate ≤28, high >28

Each component has a specific meaning:

  • Tender joint count — The tender joint count recorded for the scenario being assessed.
  • Swollen joint count — The swollen joint count recorded for the scenario being assessed.
  • Patient pain VAS — The patient pain vas recorded for the scenario being assessed.
  • CRP — The crp recorded for the scenario being assessed.

Note: Interpret the dapsa result against the thresholds and context described above.

How to Use

Enter the tender joint count, swollen joint count, patient pain VAS, CRP for the scenario you are assessing. Calculates the Disease Activity in PSoriatic Arthritis (DAPSA) score using tender joint count (68 joints), swollen joint count (66 joints), patient global assessment (0–10 VAS), patient pain VAS (0–10), and CRP (mg/dL). Remission ≤4, low ≤14, moderate ≤28, high >28. Use the dapsa result to inform your calculation.
