How Disease Burden Influences Medication Patterns for Medicare Beneficiaries: Implications for Policy
Provides benchmarks for assessing the quality of pharmaceutical care under the Medicare Part D prescription drug benefit. Examines how the beneficiaries? medication regimens evolve in the context of multiple chronic conditions and accumulating morbidity
Multimodal Machine Learning for Automated ICD Coding
This study presents a multimodal machine learning model to predict ICD-10
diagnostic codes. We developed separate machine learning models that can handle
data from different modalities, including unstructured text, semi-structured
text and structured tabular data. We further employed an ensemble method to
integrate all modality-specific models to generate ICD-10 codes. Key evidence
was also extracted to make our prediction more convincing and explainable. We
used the Medical Information Mart for Intensive Care III (MIMIC -III) dataset
to validate our approach. For ICD code prediction, our best-performing model
(micro-F1 = 0.7633, micro-AUC = 0.9541) significantly outperforms other
baseline models including TF-IDF (micro-F1 = 0.6721, micro-AUC = 0.7879) and
Text-CNN model (micro-F1 = 0.6569, micro-AUC = 0.9235). For interpretability,
our approach achieves a Jaccard Similarity Coefficient (JSC) of 0.1806 on text
data and 0.3105 on tabular data, where well-trained physicians achieve 0.2780
and 0.5002 respectively.Comment: Machine Learning for Healthcare 201
The Medicare Part D Coverage Gap: Costs and Consequences in 2007
Analyzes data on Medicare Part D enrollees who reached the coverage gap and had to pay the full cost until they qualified for catastrophic coverage, who then stopped taking their medications or bought cheaper ones, and who received catastrophic coverage
