Health maintenance organization (HMO) performance and consumer complaints: an empirical study of frustrating HMO activities.

Growing public interest in the operations of managed care plans has fueled a variety of activities to collect and analyze their performance. These activities include studies of financial performance, analysis of enrollment decisions, and, more recently, the development of systems for measuring healthcare quality to improve accountability to consumers. In this study, the authors focus on the activities of managed care plans that may frustrate patients and providers and, subsequently, motivate patients to file complaints. Using data from three sources, they evaluate the relationships between complaints against managed care plans and two metrics of performance: (a) the financial performance of the plan, and (b) the quality of care provided. Their findings indicate that complaints against health maintenance organizations are significantly related to the plans' levels of quality and to actions that may impede access to care.
