This is a drug utilization study using retrospective database analysis where study will combine data from two sources of patient-level drug utilization data for Intuniv:~i) NostraData database: longitudinal participant level prescription database ii) Physician survey: de-identified participant data provided by representative physicians in Australia~In the NostraData database, actual prescription data are collected, which allows generation of information on drug usage. However, these prescription data do not contain patient variables such as age and indication needed to monitor potential off-label use. Therefore, these data must be supplemented with another data source. The physician survey will provide the data not included in the NostraData database.
This study will evaluate and analyze prescribing behaviors of physicians and determine whether Intuniv was correctly prescribed in Australia.
