Managed care arrangements of health networks and systems. A review of the 1999 experience.

The 1990s witnessed various health provider efforts to integrate health care delivery with financing functions. Physician and hospital-led organizations developed their own insurance products and also contracted on a capitated or shared-risk basis with health maintenance organizations (HMOs). Several studies exist on the efforts of physician-led health organizations in these areas, but few studies exist on hospital-led organizations. We examined unique data on hospital-led health networks and systems for 1999 and found that about 60% had provider-owned insurance products and 50% held capitated contracts for their affiliates. In addition, these hospital-led organizations--especially health systems--had comparable levels of capitated contracting when compared to physician-led organizations. Although interest in capitation has waned, current economic realities may reignite interest in these arrangements given their potential for containing health expenditures without increasing consumer risk. In light of this, it is now a good time for physicians and medical group managers to reflect on their experiences in the 1990s and to assess the merits and shortcomings of different intermediary organizations with which they may align.
