No state has more experience with retail clinics than Minnesota, the birthplace nearly eight years ago of MinuteClinic, which still dominates the field even as competitors crowd in. An independent, nonprofit coalition of doctors, insurers, consumers, and employers called MN Community Measurement annually rates health clinics' and doctors' practices statewide.
"Lo and behold," said Jim Chase, executive director of MN Community Measurement, "the MinuteClinic actually did very well."
The most recent report card from the group, based on data from 2006, awarded MinuteClinic the highest marks in Minnesota for treating children 2 to 18 years old for sore throats, giving it a score of 99 percent. The lowest grade: 26 percent for a doctors' group.
