Abstract: Example apparatus and methods concern a clinical decision support system for the selection of candidates. A clinical decision support system includes a candidate data logic that receives electronic data that identifies candidate data, including symptom and non-symptom data, for a candidate. The clinical decision support system also includes a scoring logic that generates a score for the candidate based, at least in part, on a set of rules being applied to the candidate data. The set of rules is based on patient data of a set of patients. The clinical decision support system further includes an identification logic that identifies a personalized treatment for the candidate based, at least in part, on the score.
