External validation of an opioid misuse machine learning classifier in hospitalized adult patients.
This study looks at new methods to make opioid misuse screening in hospitals less resource-intensive, which causes it to occur rarely. The objective of this study is to externally validate the author’s previously published and open-source machine learning classifier by implementing it a different hospital to identify cases of opioid misuse. An observational cohort of 56,227 adult hospitalizations from October 2017 to December 2019 was used during a hospital-wide substance use screening program with manual screening. A manually completed Drug Abuse Screening Test served as the reference standard to validate a convolutional neural network (CNN) classified with coded word embedding features to capture electronic health record (EHR) clinical notes. Manual screening was completed in 67.8% of patients with 1.1% identified with opioid misuse. The opioid misuse classifier had good discrimination during external validation and may help overcome manual screening barriers.
