CIOMS/RUCAM scale
CIOMS/RUCAM scale is a widely used and validated method for assessing causality in cases of suspected drug-induced liver injury (DILI) and herb-induced liver injury (HILI). The scale was developed by the Council for International Organizations of Medical Sciences (CIOMS) and the Roussel Uclaf Causality Assessment Method (RUCAM).
Overview[edit | edit source]
The CIOMS/RUCAM scale is a structured, quantitative tool that provides a standardized method for assessing causality in cases of suspected DILI and HILI. It is based on a scoring system that takes into account the time to onset of the liver injury, the course of the injury after discontinuation of the drug or herb, risk factors, concomitant drugs, non-drug causes of the liver injury, and previous information about the hepatotoxicity of the drug or herb.
Scoring System[edit | edit source]
The scoring system of the CIOMS/RUCAM scale ranges from -9 to +14. A score of less than 0 indicates that the drug or herb is "excluded" as a cause of the liver injury. A score of 1-2 is "unlikely", 3-5 is "possible", 6-8 is "probable", and >8 is "highly probable".
Use in Clinical Practice[edit | edit source]
In clinical practice, the CIOMS/RUCAM scale is used to help determine whether a drug or herb is the likely cause of a patient's liver injury. This can be particularly useful in cases where the patient is taking multiple medications or supplements, and it is unclear which one may be responsible for the liver injury.
Limitations[edit | edit source]
While the CIOMS/RUCAM scale is a valuable tool, it does have some limitations. For example, it may not be as accurate in cases of chronic liver injury, or in cases where the patient has taken multiple drugs or herbs that could potentially cause liver injury.
