His research examines health care efficiency and quality improvement, focusing on low-value care in Medicare, hospital performance metrics, and insurer coverage rules. Recent studies quantify physician-level variation in low-value service provision and organizational impacts on care patterns.
While observable physician characteristics (e.g., academic rank, publication history) explain minimal variation (≤1.4% within organizations), his work highlights the dominance of physician practice patterns in driving wasteful care. Sensitivity analyses confirm consistency across narrower service sets.
Key findings:
- Physicians at 90th percentile within organizations provide 61% more low-value services than those at 10th percentile
- Panel size and pharmaceutical payments show significant associations with low-value care rates
His work has been supported by National Institute on Aging grants (P01 AG032952, F30 AG044106-01A1), with methodological contributions to multilevel modeling of health care quality metrics.
