This study introduces the ODD dataset to detect opioid-related aberrant behaviors (ORABs) from electronic health records. Prompt-tuning NLP models show promise, outperforming fine-tuning, especially for identifying less common ORABs.
Area of Science:
- Biomedical Natural Language Processing
- Clinical Informatics
- Opioid Use Disorder Research
Background:
- Opioid-related aberrant behaviors (ORABs) are significant risk factors for opioid overdose.
- Accurate identification of ORABs from clinical notes is crucial for patient safety.
- Existing methods for ORAB detection lack comprehensive datasets.
Purpose of the Study:
- Introduce the Opioid-related Aberrant Behavior Detection (ODD) dataset, a novel biomedical NLP resource.
- Facilitate the development and evaluation of NLP models for ORAB identification.
- Classify ORABs into nine distinct categories within electronic health records.
Main Methods:
- Developed an expert-annotated dataset (ODD) comprising patients' EHR notes.
- Utilized two state-of-the-art NLP approaches: fine-tuning and prompt-tuning.
- Evaluated model performance across nine ORAB categories using macro average area under the precision-recall curve.
Main Results:
- Prompt-tuning NLP models generally outperformed fine-tuning models in ORAB detection.
- Performance gains were most pronounced for identifying less common ORAB categories.
- The best model achieved a macro average area under the precision-recall curve of 88.17%.
Conclusions:
- The ODD dataset provides a valuable resource for advancing ORAB detection research.
- Prompt-tuning demonstrates superior performance for identifying diverse ORABs, including rare instances.
- Further improvements are needed for enhanced detection of uncommon ORAB categories.
