  • Impact Of Health Care Delivery System Innovations On Total Cost Of Care [Care Innovation Research Synthesis].

    Using delivery system innovations to advance health care reform continues to be of widespread interest. However, it is difficult to generalize about the success of specific types of innovations, since they have been examined in only a few studies. To gain a broader perspective, we analyzed the results of forty-three ambulatory care programs funded by the first round of the Center for Medicare and Medicaid Innovation’s Health Care Innovations Awards. The innovations’ impacts on total cost of care were estimated by independent evaluators using multivariable difference-in-differences models. Through the first two years, most of the innovations did not show a significant effect on total cost of care. Using meta-regression, we assessed the effects on costs of five common components of these innovations. Innovations that used health information technology or community health workers achieved the greatest cost savings. Savings were also relatively large in programs that targeted clinically fragile patients—clinically complex populations at risk for disease progression. While the magnitude of these effects was often substantial, none achieved conventional levels of significance in our analyses. Meta-analyses of a larger number of delivery system innovations are needed to more clearly establish their potential for patient care cost savings.

    The patient-centered medical home (PCMH) model emphasizes comprehensive, coordinated, patient-centered care, with the goals of reducing spending and improving quality. To evaluate the impact of PCMH initiatives on utilization, cost, and quality, we conducted a meta-analysis of methodologically standardized findings from evaluations of eleven major PCMH initiatives. There was significant heterogeneity across individual evaluations in many outcomes. Across evaluations, PCMH initiatives were not associated with changes in the majority of outcomes studied, including primary care, emergency department, and inpatient visits and four quality measures. The initiatives were associated with a 1.5 percent reduction in the use of specialty visits and a 1.2 percent increase in cervical cancer screening among all patients, and a 4.2 percent reduction in total spending (excluding pharmacy spending) and a 1.4 percent increase in breast cancer screening among higher-morbidity patients. These associations were significant. Identification of the components of PCMHs likely to improve outcomes is critical to decisions about investing resources in primary care.

  • Alzheimer's Disease In African Americans: Risk Factors And Challenges For The Future [Research Challenges].
    Barnes, L. L., Bennett, D. A.
    Health Affairs. April 07, 2014

    As the US elderly population continues to expand rapidly, Alzheimer’s disease poses a major and increasing public health challenge, and older African Americans may be disproportionately burdened by the disease. Although African Americans were generally underincluded in previous research studies, new and growing evidence suggests that they may be at increased risk of the disease and that they differ from the non-Hispanic white population in risk factors and disease manifestation. This article offers an overview of the challenges of Alzheimer’s disease in African Americans, including diagnosis issues, disparities in risk factors and clinical presentation of disease, and community-based recommendations to enhance research with this population.

  • Obstacles And Opportunities In Alzheimer's Clinical Trial Recruitment [Research Challenges].
    Watson, J. L., Ryan, L., Silverberg, N., Cahan, V., Bernard, M. A.
    Health Affairs. April 07, 2014

    The 2012 National Plan to Address Alzheimer’s Disease set an ambitious goal: to both prevent and effectively treat Alzheimer’s disease by 2025. To reach this goal, tens of thousands of volunteers will be needed to participate in clinical trials to test promising new interventions and therapies. To mobilize these volunteers and their health care providers to participate in future clinical trials, it will be necessary to achieve a better understanding of the barriers keeping people from participating in Alzheimer’s research; form innovative partnerships among researchers, health care and social service providers, and the public; and develop more-effective outreach strategies. In this article we explore recruitment issues, including those unique to Alzheimer’s studies, and we suggest concrete steps such as establishing a structured consortium linking all of the registries of Alzheimer’s trials and establishing new partnerships with community and local organizations that can build trust and understanding among patients, caregivers, and providers.
