Page 674-680. an identification of causal drug adverse event that is based on the Drug Interaction Probability Scale (DIPS). The DIPS uses a series of questions relating to the potential drug interaction to estimate a probability score. As a comparison, the Naranjo scale has proved to be useful for assessing the causality of adverse events, particularly for single-drug adverse drug reactions. DIPS involves in two drugs: the drug that is affected (object drug) and the drug that causes the change to the object drug (precipitant drug). YH DIPS question DIPS score
