The AHRQ Multiple Chronic Conditions Research Network Project Summary More than a quarter of all Americans—and two out of three older Americans—are estimated to have at least two chronic physical or behavioral health problems. Treatment for people living with these multiple chronic conditions (MCC) currently accounts for an estimated 66% of the Nation's health care costs. As the U.S. population ages, the number of patients with MCC continues to grow. This mounting challenge has become a major public health issue that is linked to suboptimal health outcomes and rising health care costs. As part of its ongoing effort to improve care for patients with MCC through evidence-based research, the Agency for Healthcare Research and Quality (AHRQ) has funded the AHRQ MCC Research Network. The Network aligns with a Department of Health and Human Services (HHS) effort to address MCC issues; specifically, to increase clinical, community, and patient-centered health research on MCC.AHRQ's MCC Research Network aims to improve understanding about which interventions provide the greatest benefit to patients with MCC, the safety and effectiveness of interventions that may be affected by MCC, and interventions that may need to be modified for specific patient populations. Over time, this foundational research can begin to help our country meet the needs of Americans living with MCC.The MCC Research Network includes:Eighteen exploratory and developmental (R21) grants funded in 2008 to begin addressing the gap in knowledge about patients with MCC, with a focus on the use of preventive services. Additional funding in 2009 was awarded to two of the original 18 grantees to support collaborative activities.Thirteen infrastructure development (R24) grants funded in 2010 to create new datasets for improved examination of care for patients with MCC. Each project also includes a pilot study to demonstrate the use of its newly developed infrastructure. Datasets will be made available to interested researchers and other stakeholders when these grants are completed.Fourteen exploratory (R21) grants funded in 2010 to use existing data to conduct comparative effectiveness research for patients with MCC. This research will help prioritize testing and treatments for these patients and suggest adaptations to currently recommended preventive and care management guidelines.A Learning Network and Technical Assistance Center (the Center) to encourage collaboration among the MCC investigators and provide them with technical support. The Center is staffed by Abt Associates, the MacColl Center for Healthcare Innovation, and the Inter-University Consortium for Political and Social Research.For more information about the AHRQ MCC Research Network, including profiles of the individual grants, please visit: http://www.ahrq.gov/professionals/prevention-chronic-care/decision/mcc/.To find datasets and related materials developed as a part of this project, please visit: http://www.icpsr.umich.edu/icpsrweb/AHRQMCC/ .Exploratory (R21) GrantsDetermining Processes of Cardiovascular Care Relevant to Complex PatientsElizabeth Bayliss, Kaiser Foundation Research InstituteShould High-Risk Statin Utilization Rates Be Increased for Complex AMI Patients?John M.
