Medical Scores – R
RHEUMATOID ARTHRITIS (RA):
- A score of 6/10 is needed for classification of a patient as having definite RA. Patients with a score <6/10 can be reassessed and criteria might be fulfilled cumulatively over time.
Score | ||
Joint involvement |
1 large joint (shoulder, elbow, hip, knee, ankle) | 0 |
2–10 large joints | 1 | |
1–3 small joints (MCP, PIP, Thumb IP, MTP, wrists) | 2 | |
4–10 small joints | 3 | |
>10 joints (at least 1 small joint) | 5 | |
Serology | Negative RF and negative ACPA | 0 |
Low-positive RF or low-positive anti-CCP antibodies (> ULN but ≤ 3 times ULN) | 2 | |
High-positive RF or high-positive anti-CCP antibodies (>3 times ULN) | 3 | |
Acute-phase reactants
|
Normal CRP and normal ESR | 0 |
Abnormal CRP or abnormal ESR | 1 | |
Duration of symptoms
|
<6 weeks | 0 |
≥ 6 weeks | 1 |
2010 ACR/EULAR CLASSIFICATION CRITERIA FOR RHEUMATOID ARTHRITIS:
(Score-based algorithm: add score of categories A-D; a score of 6/10 for definite RA)
Criteria | Score | Comments |
A. Joint involvement (swollen or tender)
1 large joint (shoulders, elbows, hips, knees, and ankles) 2-10 large joints 1-3 small joints (MCPs, PIPs, wrists, 2nd-5th MTPs) 4-10 small joints >10 joints (at least 1 small joint) |
0 1 2 3 5 |

B. Serology
Negative RF and negative Anti-CCP Low-positive RF or low-positive Anti-CCP (<3x ULN) High-positive RF or high-positive Anti-CCP (>3x ULN) |
0 2 3 |
Total score of ≥6: definite RA
Must have ≥1 joint with definite clinical swelling, not better explained by other disease |
C. Acute phase reactants
Normal CRP and normal ESR Abnormal CRP and abnormal ESR |
0 1 |

D. Duration of symptoms
<6 wk ≥6 wk |

RANSON SCORE: ( MNEMONIC – LAGAW BUCHOW):
On admission
o L- LDH >350 u/l o A- AST >250 sigma frankel units % o G- Glucose >200 mg/dl or > 1.1 mmol/l o A- Age>55 yrs o W- WBC Count >16000/mm3 |
Within 48 hrs
o B-Base deficit > 4 mmol/l o U- Blood Urea N2 >5 mg/dl o C- Calcium <2.0 mmol/l o H- Haematocrit fall >10% o O- Arterial 02 saturationPa02 <60 mmHg o W- Water sequestration >6l |
- Ranson’s score > 3 is said to be severe AP.
