# Model for End-stage Liver Disease (MELD) score
|
|
|
|
#### MELD score is a numerical value that is used to predict the 3-month mortality prediction risk of a patient. It is also used to prioritize patients for liver transplantations with higher score indicating a more urgent need.
|
|
### Parameters needed
|
|
| Parameter | Unit |
|
|
| --------- | ---- |
|
|
| Serum Bilirubin | mg/dL |
|
|
| Serum Creatinine | mg/dL |
|
|
| International Normalized Ratio (INR) | - |
|
|
### MELD Score interpretation table:-
|
|
|
|
| Score range | Mortality risk |
|
|
| ----------- | -------------- |
|
|
| less than 9 | Low risk (under 1.9%) |
|
|
| 10 to 19 | Low to Moderate (6.0% - 19.6%) |
|
|
| **20 to 29** | **Moderate risk (19.6% - 52.6%)** |
|
|
| **30 to 39** | **High risk (52.6% - 71.3%)** |
|
|
| **more than 40** | **Extremely high risk (71.3% - 100%)** |
|
|
|
|
### Formula to calculate MELD:-
|
|
The MELD score is calculated using the following formula:-
|
|
|
|
$$
|
|
\textbf{MELD} = (9.57 \times \ln(\text{Serum Creatinine})) + (3.78 \times \ln(\text{Serum Bilirubin})) + (11.2 \times \ln(\text{INR})) + 6.43
|
|
$$
|
|
|
|
### Notice:-
|
|
The MELD score is not considered accurate for advanced liver diseases. Other calulcators like MELD-Na should be used before taking clinical decisions |
