External validation of a machine learning classifier to identify unhealthy alcohol use in hospitalized patients.
This study’s objective was to validate a machine learning approach to alcohol screening using a natural language processing (NLP) classifier developed at an independent medical center. This retrospective cohort study took place at a midwestern US tertiary-care, urban medical center that has an inpatient structured universal screening model for unhealthy substance use and an active addiction consult service. The cohort included 57,605 unplanned admissions of adult patients between October 23, 2017 and December 31, 2019 with electronic health record (EHR) documentation of manual alcohol screening. The authors examined error in manual screening and reviewed discordance between the NLP classifier and AUDIT-derived reference. The classifier demonstrated adequate sensitivity and specificity for routine clinical use as an automated screening tool for identifying at-risk patients.

The STUN (STop UNhealthy) Alcohol Use Now trial: study protocol for an adaptive randomized trial on dissemination and implementation of screening and management of unhealthy alcohol use in primary care.
This paper describes a randomized, controlled trial to evaluate the effect of primary care practice facilitation and telehealth services on evidence-based screening, counseling, and pharmacotherapy for unhealthy alcohol use in primary care practices in North Carolina with 10 or fewer providers. The study will produce important evidence about the effect of practice facilitation on uptake of evidence-based screening, counseling, and pharmacotherapy for unhealthy alcohol use when delivered on a large scale to small and medium-sized practices. The results of this rigorously conducted evaluation are expected to have a positive impact by accelerating the dissemination and implementation of evidence related to unhealthy alcohol use into primary care practices.
