Long-term monitoring of an individual patient with alcohol dependence has usually been managed by self-report, i.e., a patient is expected to honestly apprise their physician with details of their alcohol use and recovery.[2] However, due to understandable problems of memory and recall, and perhaps not complete patient honesty, self-report data is imperfect.[2] This observation had led to the use of biomarker data, and the development of digital biomarkers, to monitor alcohol-use disorder.[1,2]
