> So the study really tells us about very 'low volume' providers compared to slightly higher volume providers I don't think 'slightly higher' is accurate. The report says, "We classified physicians into thirds of patient volume: low (estimated number of total admissions <90 per year), medium (91-200 admissions), and high (>201 admissions)". So you have two-thirds of doctors whose median volume is 90 per year, and one third of doctors whose median volume is well above 201 per year. That seems to be a significant difference. > That in turn suggests the effect was pretty small. For two-thirds of doctors the effect is: "adjusted 30 day mortality rates were 10.8% for physicians aged <40 (95% confidence interval 10.7% to 10.9%)...and 12.1% for physicians aged ≥60 (11.6% to 12.5%)". I'd say that's a significant effect - certainly something that should be included in the title.
