Excess Medical Care Spending: The Categories, Magnitude, and Opportunity Costs of Wasteful Spending in the United States.

Landmark reports from reputable sources have concluded that the United States wastes hundreds of billions of dollars every year on medical care that does not improve health outcomes. While there is widespread agreement over how wasteful medical care spending is defined, there is no consensus on its magnitude or categories. A shared understanding of the magnitude and components of the issue may aid in systematically reducing wasteful spending and creating opportunities for these funds to improve public health.To this end, we performed a review and crosswalk analysis of the literature to retrieve comprehensive estimates of wasteful medical care spending. We abstracted each source's definitions, categories of waste, and associated dollar amounts. We synthesized and reclassified waste into 6 categories: clinical inefficiencies, missed prevention opportunities, overuse, administrative waste, excessive prices, and fraud and abuse.Aggregate estimates of waste varied from $600 billion to more than $1.9 trillion per year, or roughly $1800 to $5700 per person per year. Wider recognition by public health stakeholders of the human and economic costs of medical waste has the potential to catalyze health system transformation.

Reduction in US Health Care Spending Required to Meet the Institute of Medicine's 2030 Target.

Objectives. To quantify changes in US health care spending required to reach parity with high-resource nations by 2030 or 2040 and identify historical precedents for these changes.Methods. We analyzed multiple sources of historical and projected spending from 1970 through 2040. Parity was defined as the Organisation for Economic Co-operation and Development (OECD) median or 90th percentile for per capita health care spending.Results. Sustained annual declines of 7.0% and 3.3% would be required to reach the median of other high-resource nations by 2030 and 2040, respectively (3.2% and 1.3% to reach the 90th percentile). Such declines do not have historical precedent among US states or OECD nations.Conclusions. Traditional approaches to reducing health care spending will not enable the United States to achieve parity with high-resource nations; strategies to eliminate waste and reduce the demand for health care are essential.Public Health Implications. Excess spending reduces the ability of the United States to meet critical public health needs and affects the country's economic competitiveness. Rising health care spending has been identified as a threat to the nation's health. Public health can add voices, leadership, and expertise for reversing this course.

Permanent Supportive Housing With Housing First to Reduce Homelessness and Promote Health Among Homeless Populations With Disability: A Community Guide Systematic Review.

CONTEXT: Poor physical and mental health and substance use disorder can be causes and consequences of homelessness. Approximately 2.1 million persons per year in the United States experience homelessness. People experiencing homelessness have high rates of emergency department use, hospitalization, substance use treatment, social services use, arrest, and incarceration. OBJECTIVES: A standard approach to treating homeless persons with a disability is called Treatment First, requiring clients be "housing ready"-that is, in psychiatric treatment and substance-free-before and while receiving permanent housing. A more recent approach, Housing First, provides permanent housing and health, mental health, and other supportive services without requiring clients to be housing ready. To determine the relative effectiveness of these approaches, this systematic review compared the effects of both approaches on housing stability, health outcomes, and health care utilization among persons with disabilities experiencing homelessness. DESIGN: A systematic search (database inception to February 2018) was conducted using 8 databases with terms such as "housing first," "treatment first," and "supportive housing." Reference lists of included studies were also searched. Study design and threats to validity were assessed using Community Guide methods. Medians were calculated when appropriate. ELIGIBILITY CRITERIA: Studies were included if they assessed Housing First programs in high-income nations, had concurrent comparison populations, assessed outcomes of interest, and were written in English and published in peer-reviewed journals or government reports. MAIN OUTCOME MEASURES: Housing stability, physical and mental health outcomes, and health care utilization. RESULTS: Twenty-six studies in the United States and Canada met inclusion criteria. Compared with Treatment First, Housing First programs decreased homelessness by 88% and improved housing stability by 41%. For clients living with HIV infection, Housing First programs reduced homelessness by 37%, viral load by 22%, depression by 13%, emergency departments use by 41%, hospitalization by 36%, and mortality by 37%. CONCLUSIONS: Housing First programs improved housing stability and reduced homelessness more effectively than Treatment First programs. In addition, Housing First programs showed health benefits and reduced health services use. Health care systems that serve homeless patients may promote their health and well-being by linking them with effective housing services.

The Salzburg Statement on Vaccination Acceptance.

Immunization represents one of the greatest public health achievements. Vaccines save lives, make communities more productive and strengthen health systems. They are critical to attaining the UN Sustainable Development Goals. Vaccination also represents value for investment in public health. It is undisputedly one of the most cost-effective ways of avoiding disease, each year preventing 2-3 million deaths globally. We the concerned scientists, public health professionals, physicians, and child health advocates issue this Salzburg Statement along with the International Working Group on Vaccination and Public Health Solutions, proclaiming our unwavering commitment to universal childhood vaccination, and our pledge to support the development, testing, implementation, and evaluation of new, effective, and fact-based communication programs. Our goal is to explain vaccinations to parents or caregivers, answer their questions, address their concerns, and maintain public confidence in the personal, family and community protection that childhood vaccines provide. Every effort will also be made to communicate the dangers associated with these childhood illnesses to parents and communities since this information seems to have been lost in the present-day narrative. While vaccine misinformation has led to serious declines in community vaccination rates that require immediate attention, in other communities, particularly in low-income countries, issues such as lack of access. and unstable supply of vaccines need to be addressed.

Making Strides Toward Health Equity: The Experiences of Public Health Departments.

OBJECTIVES: We explored the definition of health equity being used by public health departments and the extent of engagement of public health departments in activities to improve health equity, as well as facilitators and barriers to this work. DESIGN: We conducted 25 semistructured qualitative interviews with lead public health officials (n = 20) and their designees (n = 5). All interviews were transcribed and thematically analyzed. SETTING: We conducted interviews with respondents from local public health departments in the United States (April 2017-June 2017). PARTICIPANTS: Respondents were from local or state public health departments that were members of the Big Cities Health Coalition, accredited or both. RESULTS: Many departments were using a definition of health equity that emphasized an equal opportunity to improve health for all, with a special emphasis on socially disadvantaged populations. Improving health equity was a high priority for most departments and targeting the social determinants of health was viewed as the optimal approach for improving health equity. Having the capacity to frame issues of health equity in ways that resonated with sectors outside of public health was seen as a particularly valuable skill for facilitating cross-sector collaborations and promoting work to improve health equity. Barriers to engaging in work to improve health equity included lack of flexible and sustainable funding sources as well as limited training and guidance on how to conduct this type of work. CONCLUSIONS: Work to improve health equity among public health departments can be fostered and strengthened by building capacity among them to do more targeted framing of health equity issues and by providing more flexible and sustained funding sources. In addition, supporting peer networks that will allow for the exchange of resources, ideas, and best practices will likely build capacity among public health departments to effectively do this work.

Quantifying the Value of Prevention: A Survey of Public Health Departments' Quantitative and Economic Modeling Capacity.

OBJECTIVE: To improve the understanding of local health departments' (LHDs') capacity for and perceived barriers to using quantitative/economic modeling information to inform policy and program decisions. DESIGN: We developed, tested, and deployed a novel survey to examine this topic. SETTING: The study's sample frame included the 200 largest LHDs in terms of size of population served plus all other accredited LHDs (n = 67). The survey was e-mailed to 267 LHDs; respondents completed the survey online using SurveyMonkey. PARTICIPANTS: Survey instructions requested that the survey be completed from the perspective of the entire health department by LHD's top executive or designate. A total of 63 unique LHDs responded (response rate: 39%). MAIN OUTCOME MEASURE(S): Capacity for quantitative and economic modeling was measured in 5 categories (routinely use information from models we create ourselves; routinely use information from models created by others; sometimes use information from models we create ourselves; sometimes use information from models created by others; never use information from modeling). Experience with modeling was measured in 4 categories (very, somewhat, not so, not at all). RESULTS: Few (9.5%) respondents reported routinely using information from models, and most who did used information from models created by others. By contrast, respondents reported high levels of interest in using models and in gaining training in their use and the communication of model results. The most commonly reported barriers to modeling were funding and technical skills. Nearly all types of training topics listed were of interest. CONCLUSIONS: Across a sample of large and/or accredited LHDs, we found modest levels of use of modeling coupled with strong interest in capacity for modeling and therefore highlight an opportunity for LHD growth and support. Both funding constraints and a lack of knowledge of how to develop and/or use modeling are barriers to desired progress around modeling. Educational or funding opportunities to promote capacity for and use of quantitative and economic modeling may catalyze use of modeling by public health practitioners.

Expanded In-School Instructional Time and the Advancement of Health Equity: A Community Guide Systematic Review.

Expanded in-school instructional time (EISIT) may reduce racial/ethnic educational achievement gaps, leading to improved employment, and decreased social and health risks. When targeted to low-income and racial/ethnic minority populations, EISIT may thus promote health equity. Community Guide systematic review methods were used to search for qualified studies (through February 2015, 11 included studies) and summarize evidence of the effectiveness of EISIT on educational outcomes. Compared with schools with no time change, schools with expanded days improved students' test scores by a median of 0.05 standard deviation units (range, 0.0-0.25). Two studies found that schools with expanded day and year improved students' standardized test scores (0.04 and 0.15 standard deviation units). Remaining studies were inconclusive. Given the small effect sizes and a lack of information about the use of added time, there is insufficient evidence to determine the effectiveness of EISIT on academic achievement and thus health equity.

Examining the Effectiveness of Year-Round School Calendars on Improving Educational Attainment Outcomes Within the Context of Advancement of Health Equity: A Community Guide Systematic Review.

Students may lose knowledge and skills achieved in the school year during the summer break, with losses greatest for students from low-income families. Community Guide systematic review methods were used to summarize evaluations (published 1965-2015) of the effectiveness of year-round school calendars (YRSCs) on academic achievement, a determinant of long-term health. In single-track YRSCs, all students participate in the same school calendar; summer breaks are replaced by short "intersessions" distributed evenly throughout the year. In multi-track YRSCs, cohorts of students follow separate calendar tracks, with breaks at different times throughout the year. An earlier systematic review reported modest gains with single-track calendars and no gains with multi-track calendars. Three studies reported positive and negative effects for single-track programs and potential harm with multi-track programs when low-income students were assigned poorly resourced tracks. Lack of clarity about the role of intersessions as simple school breaks or as additional schooling opportunities in YRSCs leaves the evidence on single-track programs insufficient. Evidence on multi-track YRSCs is also insufficient.

The Debate About Electronic Cigarettes: Harm Minimization or the Precautionary Principle.

Two contrasting reviews (authored by Abrams et al. and Glantz & Bareham) in this volume have reached opposing conclusions on the effects of electronic cigarettes in a debate that is dividing the scientific and professional communities that have devoted careers to controlling the manufacture, advertising, sale, and use of combustible cigarettes. The research on the types, degree, and extent of harm from e-cigarettes is far from complete and, together with trends in teenage smoking and vaping, has raised new questions and prospects about the potential benefits that the new electronic products offer smokers of combustible cigarettes in quitting or at least cutting back on the known risks associated with the traditional forms of smoking. The rapidly morphing forms, constituents, promotions, and uses of the electronic varieties of the new nicotine delivery products (in this case electronic cigarettes) make research on their biological and behavioral effects moving targets. The two sides of this argument have produced a global divide on policy strategies.

Building Capacity for Evidence-Based Public Health: Reconciling the Pulls of Practice and the Push of Research.

Timely implementation of principles of evidence-based public health (EBPH) is critical for bridging the gap between discovery of new knowledge and its application. Public health organizations need sufficient capacity (the availability of resources, structures, and workforce to plan, deliver, and evaluate the preventive dose of an evidence-based intervention) to move science to practice. We review principles of EBPH, the importance of capacity building to advance evidence-based approaches, promising approaches for capacity building, and future areas for research and practice. Although there is general agreement among practitioners and scientists on the importance of EBPH, there is less clarity on the definition of evidence, how to find it, and how, when, and where to use it. Capacity for EBPH is needed among both individuals and organizations. Capacity can be strengthened via training, use of tools, technical assistance, assessment and feedback, peer networking, and incentives. Modest investments in EBPH capacity building will foster more effective public health practice.

Comparing the United States' and China's Shifting Health Challenges.

The United States and China both face the question of how to prioritize programmatic resources and policy interventions to make the greatest impact on the health of their populations. I discuss strengths and limitations of the expert panel survey used by Wu et al. in "The 20 Most Important and Most Preventable Health Problems of China: Opinions From Chinese Experts Using a Modified Delphi Process," in this issue of AJPH. I juxtapose this method with several US approaches to priority setting at the federal, state, and county levels and suggest steps for moving from research to action.

Framing the Local Context and Estimating the Health Impact of CPPW Obesity Prevention Strategies in Los Angeles County, 2010-2012.

CONTEXT: Few studies have described the range and health impacts of obesity prevention strategies in local communities supported by the Communities Putting Prevention to Work program. OBJECTIVE: To address this gap, we reviewed implemented strategies in Los Angeles County (LAC) for 3 program focus areas: physical activity-promotion, health marketing, and creation of healthy food environments. Local context and results from an impact simulation are presented. DESIGN: Information on population reach and program milestones was synthesized to describe historical and programmatic progress of the obesity prevention efforts during 2010-2012. To forecast health impacts, the Prevention Impacts Simulation Model (PRISM) was used to simulate population health outcomes, including projected changes in obesity burden and health behaviors 30 years into the future. SETTING: LAC with more than 9.8 million residents. PARTICIPANTS: Low-income adults and youth who were the intended audiences of the Communities Putting Prevention to Work program in LAC. INTERVENTION: Implemented strategies for the 3 focus areas. MAIN OUTCOME MEASURES: Documentation of program reach and PRISM forecasting of obesity rates and health impacts. RESULTS: Implemented strategies in LAC ranged from best practices in healthy food procurement (estimated reach: 600 000 students, 300 000 meals per day) to completed shared-use agreements (10+ agreements across 5 school districts) to a series of strategically designed health marketing campaigns on healthy eating (>515 million impressions). On the basis of PRISM simulations, these highlighted program activities have the potential to reduce by 2040 the number of youth (-29 870) and adults (-94 136) with obesity, youth (-112 453) and adults (-855 855) below recommended levels of physical activity, and youth (-14 544) and adults (-28 835) who consumed excess junk food, as compared with baseline (2010-2011). CONCLUSIONS: Program context and PRISM-simulated health impacts showed modest but promising results in LAC, which may lead to further population health improvements in the future. Downstream health and behavioral surveillance data are needed to confirm these estimates.

Early Childhood Education to Promote Health Equity: A Community Guide Systematic Review.

CONTEXT: Children in low-income and racial and ethnic minority families often experience delays in development by 3 years of age and may benefit from center-based early childhood education. DESIGN: A meta-analysis on the effects of early childhood education by Kay and Pennucci best met Community Guide criteria and forms the basis of this review. RESULTS: There were increases in intervention compared with control children in standardized test scores (median = 0.29 SD) and high school graduation (median = 0.20 SD) and decreases in grade retention (median = 0.23 SD) and special education assignment (median = 0.28 SD). There were decreases in crime (median = 0.23 SD) and teen births (median = 0.46 SD) and increases in emotional self-regulation (median = 0.21 SD) and emotional development (median = 0.04 SD). All effects were favorable, but not all were statistically significant. Effects were also long-lasting. CONCLUSIONS: Because many programs are designed to increase enrollment for high-risk students and communities, they are likely to advance health equity.

The Interaction Between an Individual's Acculturation and Community Factors on Physical Inactivity and Obesity: A Multilevel Analysis.

OBJECTIVES: We examined whether the interactions between primarily speaking English at home and community-level measures (median household income and immigrant composition) are associated with physical inactivity and obesity. METHODS: We pooled the 2005 and 2007 Los Angeles County Health Survey data to construct a multilevel data set, with community-level median household income and immigrant density as predictors at the community level. After controlling for individual-level demographic variables, we included the respondent's perceived community safety as a covariate to test the hypothesis that perceived public safety mediates the association between acculturation and health outcomes. RESULTS: The interaction between community median household income and primarily speaking English at home was associated with lower likelihoods of physical inactivity (odds ratio [OR] = 0.644; 95% confidence interval [CI] = 0.502, 0.825) and obesity (OR = 0.674; 95% CI = 0.514, 0.882). These odds remained significant after we controlled for perceived community safety. CONCLUSIONS: Resources in higher-income areas may be beneficial only to residents fully integrated into the community. Future research could focus on understanding how linguistic isolation affects community-level social learning and access to resources and whether this differs by family-level acculturation.

Out-of-School-Time Academic Programs to Improve School Achievement: A Community Guide Health Equity Systematic Review.

CONTEXT: Low-income and minority status in the United States are associated with poor educational outcomes, which, in turn, reduce the long-term health benefits of education. OBJECTIVE: This systematic review assessed the extent to which out-of-school-time academic (OSTA) programs for at-risk students, most of whom are from low-income and racial/ethnic minority families, can improve academic achievement. Because most OSTA programs serve low-income and ethnic/racial minority students, programs may improve health equity. DESIGN: Methods of the Guide to Community Preventive Services were used. An existing systematic review assessing the effects of OSTA programs on academic outcomes (Lauer et al 2006; search period 1985-2003) was supplemented with a Community Guide update (search period 2003-2011). MAIN OUTCOME MEASURE: Standardized mean difference. RESULTS: Thirty-two studies from the existing review and 25 studies from the update were combined and stratified by program focus (ie, reading-focused, math-focused, general academic programs, and programs with minimal academic focus). Focused programs were more effective than general or minimal academic programs. Reading-focused programs were effective only for students in grades K-3. There was insufficient evidence to determine effectiveness on behavioral outcomes and longer-term academic outcomes. CONCLUSIONS: OSTA programs, particularly focused programs, are effective in increasing academic achievement for at-risk students. Ongoing school and social environments that support learning and development may be essential to ensure the longer-term benefits of OSTA programs.
