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.

Comparison of provider-documented and patient-reported brief intervention for unhealthy alcohol use in VA outpatients.
This study sought to determine if differences in how brief intervention (BI) was implemented across health systems could lead to differences in the proportion of documented BI recalled and reported by patients across health systems. It found that the association between documented BI and patient-reported BI did not vary across VA networks in adjusted logistic regression models.
