Enrollee satisfaction with HMOs and its relationship with disenrollment.

Relying on 1997 data from a universe of 740 HMOs, this study uniquely documented, from the perspective of health plan administrators, rates of enrollee satisfaction and disenrollments. On the basis of various reporting totals per variable or indicator, the average level of satisfaction was 83.9%; the average number of disenrollments was 20,996 per plan. Among different datasets, an average of 18.9% members disenrolled per plan; an average of 10.2% were voluntary disenrollments; and an average of 18.3% were involuntary disenrollments. Plans with higher satisfaction enrollees had predominantly lower disenrollment rates, more enrollees likely to recommend plans to family or friends, fewer older enrollees, fewer male enrollees, and higher overall plan performance. To enhance the gaining and retaining of enrollees, plan administrators should closely monitor the various dimensions of satisfaction, such as services complement, quality of care, administrative efficiency, care management, enrollees' complaints, plan performance, appointment convenience, and waiting times.
