So-called high-performance networks are a recent addition to the tools that health plans and purchasers are using in an attempt to curb costs and improve quality, the study found. The hope is that if these networks influence enough enrollees to shift to higher-performing providers, physicians losing market share might be motivated to improve efficiency and quality to better compete.
"High-performance networks have gained a toehold in such markets as Boston, Milwaukee and Seattle only when large employers have been aggressive in pushing them," said Paul B. Ginsburg, Ph.D., co-author of the study and president of HSC, a nonpartisan policy research organization funded primarily by The Robert Wood Johnson Foundation.
In Boston, for example, the state agency that administers public employee health benefits required contracted plans to develop and offer high-performance networks, while the business coalition in Milwaukee was key in bringing Humanas high-performance network product to the market. In Seattle, Aetna has sizeable national accounts, including Boeing, Costco, Nordstrom and Starbucks, which were active in helping to launch a high-performance network. Even in these markets, however, enrollment in high-performance networks has not expanded much beyond the initiating employers, the study found.
Funded by the California HealthCare Foundation, the studys findings are detailed in a new HSC Issue Brief-HighPerformance Health Plan Networks: Early Experiencesavailable here. The study was based on interviews with about 20 organizations between May and September 2006, including representatives of national health plans and regional plans offering high-performance networks in Boston, Milwaukee, Seattle and California, as well providers, employers and benefits consultants in those markets.
"Employers pushing high-performance networks reported feeling as if they are out there alone and everyone else is window shopping, until theres more results on service use, costs and quality," HSC Senior Researcher Debra A. Draper, Ph.D., a study co-author along with Allison Liebhaber, an HSC research assistant.
The study also found that physicians typically responded to high-performance
networks with skepticism, with the most common complaint being lack of communication
from health plans. Physicians also had issues with the methodologies used to
determine high-performance designations, questioning the data quality and whether
sufficient sample sizes were used.
Physicians also complained about the lack of standardization in methodologies. Plans define high-performance networks differently, so some physicians are designated as high performing in one plan but not another, leading to general skepticism of these networks and the methodologies used to create them, according to the study.
Early lessons learned from the fledgling development of high-performance networks include:
