Detecting Stimulant and Opioid Misuse and Illicit Use

Section 1: Use Case Identifiers

Use Case ID: HHS-CDC-00004
Agency: HHS
Op Div/Staff Div: CDC
Use Case Topic Area: Health & Medical
Is the AI use case found in the below list of general commercial AI products and services?
None of the above.
What is the intended purpose and expected benefits of the AI?
Federal Health Survey analysis. The machine learning models created in this project will have an impact on the statistical analysis of electronic health record (EHR) data gathered through the (NHCS) National Hospital Care Survey. Furthermore, when the model is made available to the public, it may also influence the analysis of other user datasets that contain EHR clinical notes.

Certain non-therapeutic models do not have corresponding medical codes available in clinical notes and the information is only available in free-text fields. The machine learning models help to discover non-therapeutic drug use as described in EHR clinical notes which are novel insights previously impossible to gleam from EHRs without AI.
Describe the AI system's outputs.
Two machine learning models will be created, one for internal use and another for public release. In both instances, these models will be utilized alongside rule-based text analysis to ascertain whether a patient in a hospital setting has used a drug therapeutically (in accordance with medical prescription) or non-therapeutically. This information is used to gather new insights from EHRs for health statistics published through the NHCS.
Stage of Development: Acquisition and/or Development
Is the AI use case rights-impacting, safety-impacting, both, or neither?
