ATLAS Score (C. difficile Infection)
ATLAS score (Miller 2013) for Clostridioides difficile infection: Age + Antibiotics + Leukocyte count + Albumin + serum Creatinine, 0-10; predicted cure = 100 - 5.08 x score.

Example
- Age
- 1
- Systemic antibiotics during CDI therapy
- 2
- Leukocyte count
- 1
- Albumin (> 35 = 0, 26-35 = 1, <= 25 = 2) g/L
- 1
- Serum creatinine (<= 120 = 0, 121-179 = 1, >= 180 = 2) umol/L
- 1
Result: ATLAS 6 of 10 — predicted CDI cure ~69.5%.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-10
- Age + antibiotics + leukocyte + albumin + creatinine; predicted cure = 100 - 5.08 x score. A prognostic score, not a diagnosis.
What you enter
- Age (< 60 = 0, 60-79 = 1, >= 80 = 2)
- Systemic antibiotics during CDI therapy
- Leukocyte count (< 16 = 0, 16-25 = 1, > 25 = 2)
- Albumin (> 35 = 0, 26-35 = 1, <= 25 = 2) g/L
- Serum creatinine (<= 120 = 0, 121-179 = 1, >= 180 = 2) umol/L
