PCP indicates primary care physician.

a

The mean is based on the group of physicians who had at least 1 quality event attributed to them for this measure.

b

The volume categories are not mutually exclusive; a physician with 25 quality events will be included in the volume categories of 10 or more and 20 or more.

c

The proportion of physicians who meet the volume category requirements for the quality measure out of all physicians with at least 1 quality event on any quality measure (n = 97,268).

d

The reliability estimate for the mean number of quality events among physicians who meet the volume category requirements for the composite. Estimates above the recommended level are boldfaced.

e

The reliability estimate for the minimum number of quality events for the volume category. Estimates above the recommended level are boldfaced.

f

Lower performance is better for this measure.
