Medicare's Specialty-Oriented Accountable Care Organization: First-Year Results For People With End-Stage Renal Disease.

The Comprehensive End-Stage Renal Disease (ESRD) Care (CEC) Model was the first Medicare specialty-oriented accountable care organization (ACO) model. We examined whether this model provided better results for beneficiaries with ESRD than primary care-based ACO models. We found significant decreases in Medicare payments ($126 per beneficiary per month), hospitalizations (5 percent), and likelihood of readmissions (8 percent) among beneficiaries with ESRD during the first year of alignment with the CEC Model and no impacts on these measures among beneficiaries with ESRD who were aligned with primary care-based ACOs, relative to fee-for-service Medicare beneficiaries. Neither the CEC nor primary care-based ACO models significantly reduced the likelihood of catheter use, but fistula use increased for CEC Model beneficiaries to levels just above statistical significance. Other populations with chronic conditions may benefit from the testing of a specialty-oriented ACO model. In addition, primary care-based ACOs may benefit from applying CEC Model strategies to high-need subpopulations. Last, the strategies that enabled ESRD Seamless Care Organizations to achieve reductions in hospitalizations and readmissions even without hospital participation as owners could inform physician-led ACOs' efforts to coordinate with hospitals in their areas.

Biobanks in the United States: how to identify an undefined and rapidly evolving population.

As part of a larger organizational study, we sought to survey biobanks in the United States. However, we encountered two problems with this population. First, no common definition of biobanks exists. Second, no census is available of these facilities from which to sample in order to implement a survey. In light of these problems, we employed a multifaceted approach using electronic searches of PubMed, RePORTER, and Google. In addition, we systematically searched for biobanks housed within universities that have NIH-designated Clinical and Translational Science Awards (CTSA). We expanded this part of the search by looking for biobanks among all members of the American Association of Medical Colleges (AAMC). Finally, we added banks to our database found previously by other researchers and banks found via correspondence with our colleagues. Our search strategy produced a database of 624 biobanks for which we were able to confirm contact information in order to conduct our online survey. Another 140 biobanks were identified but did not respond to our requests to confirm their existence or contact information. In order to maximize both the uniqueness of banks found and the greatest return on effort for each search, we suggest targeting resources that are already organized. In our work, these included the CTSA, AAMC, and part of the Google searches. We contend that our search provides a model for analysis of new fields of research and/or rapidly evolving industries. Furthermore, our approach demonstrates that with the appropriate tools it is possible to develop a systematic and comprehensive database to investigate undefined populations.

Advertising expenditures in the nursing home sector: evaluating the need for and purpose of advertising.

Marketing and advertising activities in the nursing home sector have increased in recent years, following the example of hospitals and health systems. The reasons for this trend may be related to the growth in competition but are not clearly identified yet. Theoretically, advertising becomes necessary to gain an advantage over the competition. The purpose of this study was to identify the reasons for the variation in advertising expenditures among nursing homes in Texas. For this study, we merged 2003 data from the Texas Medicaid Nursing Facility Cost Report, the Texas Nursing Home Quality Reporting System, and the Area Resource File for Texas. Using the Herfindahl-Hirschman Index, we then examined the correlations between advertising expenses and the level of market concentration. We evaluated the association between advertising expenditures and market competition using two logistic and four linear regression models. Total advertising expenses in Texas nursing homes ranged from $0 to $165,000 per year. Higher advertising expenditures were associated with larger facilities, higher occupancy, and high Medicare census. Market competition, however, was not a significant predictor of such expenses. Advertising seems to be more resource-driven than market-driven. Therefore, some advertising expenditures may be unnecessary, may lack impact, and may even be wasteful. Reducing unnecessary advertising costs could free up resources, which may be allocated to necessary resident care activities.
