From DSM/ICD to precision staging models. The DSM/ICD model classifies patients into particular conditions according to clinical-based criteria. DSM/ICD diagnosis can be refined by course specifiers. The staging model allows placing the patient in a particular stage according to the extent of illness progression, starting from at-risk stages (stage 1) to more chronic ones (stage 3). However, there can still be differences between patients within a particular stage. A precision staging model would then use the new advances on precision medicine to better characterize the patients and offer them a more personalized treatment.
