Chicago project provides insights into improving managed care.

Managed care enrollees are generally more satisfied with their HMO, PPO, and POS plans than their employers expected they'd be. But both consumers and employers think health plans can improve on member services and efficient delivery of care. These results come from a Chicago Business Group on Health project involving 14 employers, 7 health plans, and 22,000 surveyed employees. The study's multi-dimensional design and emphasis on improving health plan performance make it a model from which others may learn.
