The authors examine the issue of continuity, which is directly associated with patient satisfaction, from the perspective of the physician. They attempt to determine which factors are most important in determining physician satisfaction with an HMO and the link between satisfaction with an HMO and intent to remain affiliated with that HMO. Their study reveals that 11 factors explain 71% of the variation in overall physician satisfaction and that a physician's satisfaction with a plan is closely linked to intentions to reenroll. Implications for HMOs, physicians, employers, and public policy makers are explored.
