Dr. Christopher Tompkins, IHS Director Welcome to the Institute on Healthcare Systems


The Institute on Healthcare Systems (IHS) is home to many innovations in healthcare research and policy, and is dedicated to providing rigorous technical solutions to policymakers and other stakeholders who are striving to improve quality, efficiency, and value.  We respect the complexity of healthcare, the corresponding need for rigorous and robust approaches to meaningful and stable reform, and the vital strength of empirical illumination and validation.

IHS was built originally on the vast experience in national health policy of our founders, Stuart Altman and Stan Wallack. Their tradition continues with accomplishments of our director, Christopher Tompkins, including his leadership in developing the shared-savings payment model and related delivery system innovations, hospital value-based purchasing, and currently, a comprehensive episode-of-care system for Medicare and the public domain.  Similarly, our deputy director, Jennifer Perloff, has led IHS studies in value for capitated delivery systems, and the potential roles of nurse practitioners to implement sustainable delivery system reforms.

Christine Bishop is a national expert on financing of post-acute and long-term care, as well as the economics of healthcare labor markets.  Donald Shepard and colleagues have done pioneering and enduring work in cost-effectiveness analysis, domestically and internationally.  John Chapman, Moaven Razavi and Chris Sistrom are leaders in developing groundbreaking tools and approaches for transforming substantial aspects of healthcare services.

IHS staff also covers a range of delivery systems issues, such as Cindy Thomas' work in prescription drug policy and state health reform. Given the broad range of work done at IHS, our research spans both quantitative and qualitative techniques. Jeff Prottas, for example, is an expert in program implementation and evaluative case studies. Grant Ritter and Predipta Seal provide expertise in statistics and econometric methods.  Palmira Santos spearheads organizational and delivery system reforms aimed at improving quality for vulnerable populations ranging from neonates to the elderly.  

As health care organizations increasingly enter new reimbursement arrangements like global and episode-based payment, Rob Mechanic has led several new studies evaluating how organizations are adapting to these new payment models.

Policy analysis is an important component of the work at IHS and is led by Rob Mechanic at the Health Industry Forum and Michael Doonan at the Massachusetts Health Policy Forum. Their supporting team includes Palmira Santos, Darren Zinner and Ellen Grody.

Nurse practitioner patients less costly to Medicare than physician patients

First national study contradicts previous research on health care costs

With Medicare enrollment and cost concerns growing, a new study finds that patients with a nurse practitioner as a primary care provider are less costly to Medicare than patients with a physician primary care provider. The study—the first to examine national data—contradicts previous research suggesting that both types of providers generate equal costs or that nurse practitioners actually cost Medicare more.  Continue reading....

Tiered and Limited Network Health Insurance Plans:  Balancing Access and Affordability

Tiered and limited network health insurance plans are reemerging as efforts to limit the growth of health spending have intensified. In 2014, these products were 48 percent of the plans offered on the new Health Exchanges and cost 17 percent less, on average, than broad network products. They have also become more prevalent in employer-sponsored programs with 18% of large employers offering a tiered or “high-performance” network in 2014.
