<qa>  What is the first part of the project?The investigators have approved protocol amendment to use the data from the study. The investigators aim to identify these patients by building a statistical model based on significant variables from the data collected in the ongoing randomised controlled trial. The hypothesis for the first part of the project is that a set of patient characteristics can identify patients who are at high risk of drug-related readmissions and who would benefit most from the pharmaceutical intervention. The model will be validated using data from 100 new patients admitted to the internal medicine ward.
