In Reply.—Drs Allen and Foldes and Drs
Rich and Kralewski reiterate a point we previously made: that physician ratings
of health plans could be confounded by various factors. They cite plan type,
whether physicians are employed by a plan, and underlying attitudes toward
managed care as particularly problematic. We agree that if such confounding
occurs it should be addressed. However, because this pilot study was limited
to 3 plans in the Twin Cities metropolitan area (where there is only 1 staff
model HMO), it was not possible, as Allen and Foldes recognize, to control
for plan type. There are no well-established methods to control for physicians'
attitudes toward managed care. We currently are launching a national multisite
study that will enable us to determine whether such confounding exists and
to control for it.
