The Massachusetts 2006 health care reform has been called a model for the Affordable Care Act. The law attained near-universal insurance coverage and increased access to care. Its effect on population health is less clear.

Few remedies effectively treat long-term pain and disability from knee osteoarthritis. Studies suggest that Tai Chi alleviates symptoms, but no trials have directly compared Tai Chi with standard therapies for osteoarthritis.

Before Canada’s single-payer reform, its payment system, health costs, and number of health administrative personnel per capita resembled those of the United States. By 1999, administration accounted for 31% of U.S. health expenditures versus 16.7% in Canada. No recent comprehensive analyses of those costs are available.

Although consumption of tea at high-temperatures has been suggested as a risk factor for esophageal cancer, an association has not been observed consistently, and whether any relationship is independent of alcohol and tobacco exposure has not been evaluated.

This paper is part of the American College of Physicians' policy framework to achieve a vision for a better health care system, where everyone has coverage for and access to the care they need, at a cost they and the country can afford. Currently, the United States is the only wealthy industrialized country that has not achieved universal health coverage. The nation’s existing health care system is inefficient, unaffordable, unsustainable, and inaccessible to many. Part 1 of this paper discusses why the United States needs to do better in addressing coverage and cost. Part 2 presents 2 potential approaches, a single-payer model and a public choice model, to achieve universal coverage. Part 3 describes how an emphasis on value-based care can reduce costs.

BACKGROUND: Suboptimum medication adherence is common in the United States and leads to serious negative health consequences but may respond to intervention. PURPOSE: To assess the comparative effectiveness of patient, provider, systems, and policy interventions that aim to improve medication adherence for chronic health conditions in the United States. DATA SOURCES: Eligible peer-reviewed publications from MEDLINE and the Cochrane Library indexed through 4 June 2012 and additional studies from reference lists and technical experts. STUDY SELECTION: Randomized, controlled trials of patient, provider, or systems interventions to improve adherence to long-term medications and nonrandomized studies of policy interventions to improve medication adherence. DATA EXTRACTION: Two investigators independently selected, extracted data from, and rated the risk of bias of relevant studies. DATA SYNTHESIS: The evidence was synthesized separately for each clinical condition; within each condition, the type of intervention was synthesized. Two reviewers graded the strength of evidence by using established criteria. From 4124 eligible abstracts, 62 trials of patient-, provider-, or systems-level interventions evaluated 18 types of interventions; another 4 observational studies and 1 trial of policy interventions evaluated the effect of reduced medication copayments or improved prescription drug coverage. Clinical conditions amenable to multiple approaches to improving adherence include hypertension, heart failure, depression, and asthma. Interventions that improve adherence across multiple clinical conditions include policy interventions to reduce copayments or improve prescription drug coverage, systems interventions to offer case management, and patient-level educational interventions with behavioral support. LIMITATIONS: Studies were limited to adults with chronic conditions (excluding HIV, AIDS, severe mental illness, and substance abuse) in the United States. Clinical and methodological heterogeneity hindered quantitative data pooling. CONCLUSION: Reduced out-of-pocket expenses, case management, and patient education with behavioral support all improved medication adherence for more than 1 condition. Evidence is limited on whether these approaches are broadly applicable or affect long-term medication adherence and health outcomes.
