Variation in medicine and surgery is a critical contemporary health policy issue. Recent research demonstrates that variation in Medicare payments to otolaryngologists in a single metropolitan area was attributable to differences in health care resource utilization among physicians and that the hospital with the highest Medicare payments per physician had a higher proportion of office endoscopy-related relative value units than that of other providers, relying less on evaluation and management office visits for revenue. This study is the latest in a line of fascinating case records of variation in otolaryngology and other surgical specialties dating back to the work of J. Alison Glover in 1938.
