A new study in the CTN, CTN-0073-Ot (Towards Detecting Cocaine Use Using Smartwatches in the NIDA Clinical Trials Network), will be investigating methods for detecting cocaine use from heart rate data captured by smartwatches, with the aim to deploy such an approach widely in the NIDA Clinical Trials Network (CTN) and beyond.
This method will enable researchers to automatically detect cocaine use and the precise timing of such use, as well as complement self-report methods that often suffer from inaccuracy in reporting cocaine use in the field setting.
Detection of cocaine use via smartwatches will build upon, and extend, the study team’s recently developed methods to identify cocaine use from interbeat interval heart rate data obtained from electrocardiogram (ECG) sensors and physical activity from accelerometer data.
Three specific aims will be pursued:
