Health literacy interventions and outcomes: an updated systematic review.

Abstract: Objectives To update a 2004 systematic review of health care service use and health outcomes related to differences in health literacy level and interventions designed to improve these outcomes for individuals with low health literacy. Disparities in health outcomes and effectiveness of interventions among different sociodemographic groups were also examined. Data sources We searched MEDLINE®, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, PsychINFO, and the Educational Resources Information Center. For health literacy, we searched using a variety of terms, limited to English and studies published from 2003 to May 25, 2010. For numeracy, we searched from 1966 to May 25, 2010. Review methods We used standard Evidence-based Practice Center methods of dual review of abstracts, full-text articles, abstractions, quality ratings, and strength of evidence grading. We resolved disagreements by consensus. We evaluated whether newer literature was available for answering key questions, so we broadened our definition of health literacy to include numeracy and oral (spoken) health literacy. We excluded intervention studies that did not measure health literacy directly and updated our approach to evaluate individual study risk of bias and to grade strength of evidence. Results We included good- and fair-quality studies: 81 studies addressing health outcomes (reported in 95 articles including 86 measuring health literacy and 16 measuring numeracy, of which 7 measure both) and 42 studies (reported in 45 articles) addressing interventions. Differences in health literacy level were consistently associated with increased hospitalizations, greater emergency care use, lower use of mammography, lower receipt of influenza vaccine, poorer ability to demonstrate taking medications appropriately, poorer ability to interpret labels and health messages, and, among seniors, poorer overall health status and higher mortality. Health literacy level potentially mediates disparities between blacks and whites. The strength of evidence of numeracy studies was insufficient to low, limiting conclusions about the influence of numeracy on health care service use or health outcomes. Two studies suggested numeracy may mediate the effect of disparities on health outcomes. We found no evidence concerning oral health literacy and outcomes. Among intervention studies (27 randomized controlled trials [RCTs], 2 cluster RCTs, and 13 quasi-experimental designs), the strength of evidence for specific design features was low or insufficient. However, several specific features seemed to improve comprehension in one or a few studies. The strength of evidence was moderate for the effect of mixed interventions on health care service use; the effect of intensive self-management inventions on behavior; and the effect of disease-management interventions on disease prevalence/severity. The effects of other mixed interventions on other health outcomes, including knowledge, self-efficacy, adherence, and quality of life, and costs were mixed; thus, the strength of evidence was insufficient. Conclusions The field of health literacy has advanced since the 2004 report. Future research priorities include justifying appropriate cutoffs for health literacy levels prior to conducting studies; developing tools that measure additional related skills, particularly oral (spoken) health literacy; and examining mediators and moderators of the effect of health literacy. Priorities in advancing the design features of interventions include testing novel approaches to increase motivation, techniques for delivering information orally or numerically, "work around" interventions such as patient advocates; determining the effective components of already-tested interventions; determining the cost-effectiveness of programs; and determining the effect of policy and practice interventions.

Interventions for Individuals with Low Health Literacy: A Systematic Review

Abstract: The US Department of Health and Human Services recently called for action on health literacy An important first step is defining the current state of the literature about interventions designed to mitigate the effects of low health literacy We performed an updated systematic review examining the effects of interventions that authors reported were specifically designed to mitigate the effects of low health literacy We searched MEDLINE®, The Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Educational Resources Information Center (ERIC), and the Cochrane Library databases (2003 forward for health literacy; 1966 forward for numeracy) Two reviewers independently reviewed titles, abstracts, and full-text articles for inclusion and included studies that examined outcomes by health literacy level and met other pre-specified criteria One reviewer abstracted article information into evidence tables; a second checked accuracy Two reviewers independently rated study quality using predefined criteria Among 38 included studies, we found multiple discrete design features that improved comprehension in one or a few studies (eg, presenting essential information by itself or first, presenting information so that the higher number is better, adding icon arrays to numerical information, adding video to verbal narratives) In a few studies, we also found consistent, direct, fair or good-quality evidence that intensive self-management interventions reduced emergency department visits and hospitalizations; and intensive self- and disease-management interventions reduced disease severity Evidence for the effects of interventions on other outcomes was either limited or mixed Multiple interventions show promise for mitigating the effects of low health literacy and could be considered for use in clinical practice

Nonpharmacologic Interventions for Treatment-Resistant Depression in Adults

Abstract: Major depressive disorder (MDD) is common and costly. Over the course of a year, between 13.1 million and 14.2 million people will experience MDD. Approximately half of these people seek help for this condition, and only 20 percent of those receive adequate treatment. For those who do initiate treatment for their depression, approximately 50 percent will not adequately respond following acutephase treatment; this refractory group has considerable clinical and research interest. Patients with only one prior treatment failure are sometimes included in this group, but patients with two or more prior treatment failures are a particularly important and poorly understood group and are considered to have treatment-resistant depression (TRD). These TRD patients represent a complex population with a disease that is difficult to manage.

Drug Therapy for Rheumatoid Arthritis in Adults: An Update

Abstract: Rheumatoid arthritis (RA), which affects 1.3 million adult Americans, is an autoimmune disease that involves inflammation of the synovium (a thin layer of tissue lining a joint space) with progressive erosion of bone leading in most cases to misalignment of the joint, loss of function, and disability. The disease tends to affect the small joints of the hands and feet in a symmetric pattern, but other joint patterns are often seen. The diagnosis is based primarily on the clinical history and physical examination with support from selected laboratory tests. Treatment of patients with RA aims to control pain and inflammation and, ultimately, the goal is remission or at least low disease activity for all patients. Available therapies for RA include corticosteroids, oral disease-modifying antirheumatic drugs or DMARDs (hydroxychloroquine, leflunomide, methotrexate [MTX], and sulfasalazine), and biologic DMARDs (five anti-tumor necrosis factor drugs [anti-TNF]: adalimumab, certolizumab, etanercept, golimumab, infliximab; and others including abatacept, anakinra, rituximab, and tocilizumab).

Best Care at Lower Cost: The Path to Continuously Learning Health Care in America

Abstract: America's health care system has become too complex and costly to continue business as usual. Best Care at Lower Cost explains that inefficiencies, an overwhelming amount of data, and other economic and quality barriers hinder progress in improving health and threaten the nation's economic stability and global competitiveness. According to this report, the knowledge and tools exist to put the health system on the right course to achieve continuous improvement and better quality care at a lower cost.The costs of the system's current inefficiency underscore the urgent need for a systemwide transformation. About 30 percent of health spending in 2009--roughly $750 billion--was wasted on unnecessary services, excessive administrative costs, fraud, and other problems. Moreover, inefficiencies cause needless suffering. By one estimate, roughly 75,000 deaths might have been averted in 2005 if every state had delivered care at the quality level of the best performing state. This report states that the way health care providers currently train, practice, and learn new information cannot keep pace with the flood of research discoveries and technological advances.About 75 million Americans have more than one chronic condition, requiring coordination among multiple specialists and therapies, which can increase the potential for miscommunication, misdiagnosis, potentially conflicting interventions, and dangerous drug interactions. Best Care at Lower Cost emphasizes that a better use of data is a critical element of a continuously improving health system, such as mobile technologies and electronic health records that offer significant potential to capture and share health data better. In order for this to occur, the National Coordinator for Health Information Technology, IT developers, and standard-setting organizations should ensure that these systems are robust and interoperable. Clinicians and care organizations should fully adopt these technologies, and patients should be encouraged to use tools, such as personal health information portals, to actively engage in their care.This book is a call to action that will guide health care providers; administrators; caregivers; policy makers; health professionals; federal, state, and local government agencies; private and public health organizations; and educational institutions.

Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis

Abstract: In the United States, approximately 14 million people have had cancer and more than 1.6 million new cases are diagnosed each year. However, more than a decade after the Institute of Medicine (IOM) first studied the quality of cancer care, the barriers to achieving excellent care for all cancer patients remain daunting. Care often is not patient-centered, many patients do not receive palliative care to manage their symptoms and side effects from treatment, and decisions about care often are not based on the latest scientific evidence. The cost of cancer care also is rising faster than many sectors of medicine--having increased to $125 billion in 2010 from $72 billion in 2004--and is projected to reach $173 billion by 2020. Rising costs are making cancer care less affordable for patients and their families and are creating disparities in patients' access to high-quality cancer care. There also are growing shortages of health professionals skilled in providing cancer care, and the number of adults age 65 and older--the group most susceptible to cancer--is expected to double by 2030, contributing to a 45 percent increase in the number of people developing cancer. The current care delivery system is poorly prepared to address the care needs of this population, which are complex due to altered physiology, functional and cognitive impairment, multiple coexisting diseases, increased side effects from treatment, and greater need for social support. Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis presents a conceptual framework for improving the quality of cancer care. This study proposes improvements to six interconnected components of care: (1) engaged patients; (2) an adequately staffed, trained, and coordinated workforce; (3) evidence-based care; (4) learning health care information technology (IT); (5) translation of evidence into clinical practice, quality measurement and performance improvement; and (6) accessible and affordable care. This report recommends changes across the board in these areas to improve the quality of care. Delivering High-Quality Cancer Care: Charting a New Course for a System in Crisis provides information for cancer care teams, patients and their families, researchers, quality metrics developers, and payers, as well as HHS, other federal agencies, and industry to reevaluate their current roles and responsibilities in cancer care and work together to develop a higher quality care delivery system. By working toward this shared goal, the cancer care community can improve the quality of life and outcomes for people facing a cancer diagnosis.

Social Determinants of Risk and Outcomes for Cardiovascular Disease A Scientific Statement From the American Heart Association

Abstract: An Institute of Medicine report titled U.S. Health in International Perspective: Shorter Lives, Poorer Health documents the decline in the health status of Americans relative to people in other high-income countries, concluding that “Americans are dying and suffering from illness and injury at rates that are demonstrably unnecessary.”1 The report blames many factors, “adverse economic and social conditions” among them. In an editorial in Science discussing the findings of the Institute of Medicine report, Bayer et al2 call for a national commission on health “to address the social causes that have put the USA last among comparable nations.” Although mortality from cardiovascular disease (CVD) in the United States has been on a linear decline since the 1970s, the burden remains high. It accounted for 31.9% of deaths in 2010.3 There is general agreement that the decline is the result, in equal measure, of advances in prevention and advances in treatment. These advances in turn rest on dramatic successes in efforts to understand the biology of CVD that began in the late 1940s.4,5 It has been assumed that the steady downward trend in mortality will continue into the future as further breakthroughs in biological science lead to further advances in prevention and treatment. This view of the future may not be warranted. The prevalence of CVD in the United States is expected to rise 10% between 2010 and 2030.6 This change in the trajectory of cardiovascular burden is the result not only of an aging population but also of a dramatic rise over the past 25 years in obesity and the hypertension, diabetes mellitus, and physical inactivity that accompany weight gain. Although there is no consensus on the precise causes of the obesity epidemic, a dramatic change in the underlying biology of Americans is …
