The December issue of Health Services Research (HSR) explores a variety of research areas, including quality, children's care, Medicare, hospital care, and financial incentive. The issue leads with an editorial by AcademyHealth member Michael Chernew on the benefits of bundled payments from a physician perspective. Chernew discusses the disadvantages created by complexities and lack of financial incentives associated with fee-for-services payments, and shares his thoughts on why bundled payments can be more effective and efficient. HSR also released a companion theme issue on health services research and global health. The theme issue features work on racial gaps in child health insurance coverage, population health preferences in Liberia, and a study on HIV services in Cameroon. The following AcademyHealth members have published their work in the journal this month: Why Physicians Should Like Bundled Payment Michael Chernew Comparing Patient Outcomes across Payer Types: Implications for Using Hospital Discharge Records to Assess Quality Grant Martsolf Abandonment of High-Dose Chemotherapy/Hematopoietic Cell Transplants for Breast Cancer Following Negative Trial Results David Howard and Navneet Majhail Examining Multiple Sources of Differential Item Functioning on the Clinician & Group CAHPS® Survey Hector Rodriguez Medicaid Personal Care Services and Caregivers' Reports of Children's Health: The Dynamics of a Relationship Thomas R.
