Okasako-Schmucker DL , Peng Y , Cobb J , Buchanan LR , Xiong KZ , Mercer SL , Sabatino SA , Melillo S , Remington PL , Kumanyika SK , Glenn B , Breslau ES , Escoffery C , Fernandez ME , Coronado GD , Glanz K , Mullen PD , Vernon SW . Am J Prev Med 2022 INTRODUCTION: Many in the U.S. are not up to date with cancer screening. This systematic review examined the effectiveness of interventions engaging community health workers to increase breast, cervical, and colorectal cancer screening. METHODS: Authors identified relevant publications from previous Community Guide systematic reviews of interventions to increase cancer screening (1966 through 2013) and from an update search (January 2014-November 2021). Studies written in English and published in peer-reviewed journals were included if they assessed interventions implemented in high-income countries; reported screening for breast, cervical, or colorectal cancer; and engaged community health workers to implement part or all of the interventions. Community health workers needed to come from or have close knowledge of the intervention community. RESULTS: The review included 76 studies. Interventions engaging community health workers increased screening use for breast (median increase=11.5 percentage points, interquartile interval=5.523.5), cervical (median increase=12.8 percentage points, interquartile interval=6.421.0), and colorectal cancers (median increase=10.5 percentage points, interquartile interval=4.517.5). Interventions were effective whether community health workers worked alone or as part of a team. Interventions increased cancer screening independent of race or ethnicity, income, or insurance status. DISCUSSION: Interventions engaging community health workers are recommended by the Community Preventive Services Task Force to increase cancer screening. These interventions are typically implemented in communities where people are underserved to improve health and can enhance health equity. Further training and financial support for community health workers should be considered to increase cancer screening uptake. |
A Community Guide systematic review: School dietary and physical activity interventions
Buchanan LR , Wethington HR , Finnie RKC , Mercer SL , Merlo C , Michael S , Sliwa S , Pratt CA , Ochiai E . Am J Prev Med 2022 64 (3) 441-451 CONTEXT: Schools can play an important role in supporting a healthy lifestyle by offering nutritious foods and beverages and providing opportunities for physical activity. A healthy diet and regular physical activity may reduce the risk of obesity. This manuscript reports on a Community Guide systematic review examining the effectiveness of interventions in schools combining school meal or fruit and vegetable snack programs and physical activity. EVIDENCE ACQUISITION: Studies meeting the intervention definition were identified from a literature search (search period: January 1990-November 2019). Community Guide systematic review methods were used to assess effectiveness as measured by dietary behavior, physical activity, and weight changes; analyses were conducted in 2020. EVIDENCE SYNTHESIS: Interventions (n=24 studies) were considered effective for increasing physical activity (median increase=21.8 minutes/day; interquartile interval= -0.8 to 27.4 minutes/day), modestly increasing fruit and vegetable intake (median relative increase=12.1%; interquartile interval= -4.6%, 73.4%), and decreasing the prevalence of overweight and obesity (median decrease=2.5 percentage points; interquartile interval= -8.1, -1.6 percentage points) among elementary school students through sixth grade. There were not enough studies to determine the effectiveness of interventions for middle- and high-school students. CONCLUSIONS: School meal or fruit and vegetable snack interventions combined with physical activity were effective in increasing physical activity, with modest effects for improving fruit and vegetable consumption and reducing the prevalence of overweight and obesity among elementary students. These results may inform researchers and school administrators about healthy eating and physical activity interventions. |
Intimate Partner and Sexual Violence Prevention Among Youth: A Community Guide Systematic Review
Finnie RKC , Okasako-Schmucker DL , Buchanan L , Carty D , Wethington H , Mercer SL , Basile KC , DeGue S , Niolon PH , Bishop J , Titus T , Noursi S , Dickerson SA , Whitaker D , Swider S , Remington P . Am J Prev Med 2021 62 (1) e45-e55 INTRODUCTION: Intimate partner violence and sexual violence are widespread and often occur early in life. This systematic review examines the effectiveness of interventions for primary prevention of intimate partner violence and sexual violence among youth. METHODS: Studies were identified from 2 previous systematic reviews and an updated search (January 2012-June 2016). Included studies were implemented among youth, conducted in high-income countries, and aimed to prevent or reduce the perpetration of intimate partner violence or sexual violence. In 2016-2017, Guide to Community Preventive Services (Community Guide) methods were used to assess effectiveness as determined by perpetration, victimization, or bystander action. When heterogeneity of outcomes prevented usual Community Guide methods, the team systematically applied criteria for favorability (statistically significant at p<0.05 or approaching significance at p<0.10) and consistency (75% of results in the same direction). RESULTS: A total of 28 studies (32 arms) met inclusion and quality of execution criteria. Interventions used combinations of teaching healthy relationship skills, promoting social norms to protect against violence, or creating protective environments. Overall, 18 of 24 study arms reported favorable results on the basis of the direction of effect for decreasing perpetration; however, favorability for bystander action diminished with longer follow-up. Interventions did not demonstrate consistent results for decreasing victimization. A bridge search conducted during Fall 2020 confirmed these results. DISCUSSION: Interventions for the primary prevention of intimate partner violence and sexual violence are effective in reducing perpetration. Increasing bystander action may require additional follow-up as effectiveness diminishes over time. Findings may inform researchers, school personnel, public health, and other decision makers about effective strategies to prevent intimate partner violence and sexual violence among youth. |
Sources of support for studies that inform recommendations of the Community Preventive Services Task Force
Neilson E , Villani J , Mercer SL , Tilley DL , Vincent I , Alston A , Klabunde CN . Public Health Rep 2020 135 (6) 813-822 OBJECTIVES: The Community Preventive Services Task Force (CPSTF) makes evidence-based recommendations about preventive services, programs, and policies in community settings to improve public health. CPSTF recommendations are based on systematic evidence reviews. This study examined the sponsors (ie, sources of financial, material, or intellectual support) for publications included in systematic reviews used by the CPSTF to make recommendations during a 9-year period. METHODS: We examined systematic evidence reviews (effectiveness reviews and economic reviews) for CPSTF findings issued from January 1, 2010, through December 31, 2018. We assessed study publications used in these reviews for sources of support; we classified sources as government, nonprofit, industry, or no identified support. We also identified country of origin for each sponsor and the most frequently mentioned sponsors. RESULTS: The CPSTF issued findings based on 144 systematic reviews (106 effectiveness reviews and 38 economic reviews). These reviews included 3846 publications: 3363 publications in effectiveness reviews and 483 publications in economic reviews. Government agencies supported 57.1% (n = 1919) of publications in effectiveness reviews and 59.2% (n = 286) in economic reviews. More than 1500 study sponsors from 36 countries provided support. The National Institutes of Health was the leading sponsor for effectiveness reviews (21.3%; 718 of 3363) and economic reviews (16.2%; 78 of 480), followed by the Centers for Disease Control and Prevention (7.0%; 234 of 3363 effectiveness reviews and 14.8%; 71 of 480 economic reviews). CONCLUSIONS: The evidence base used by the CPSTF was supported by an array of sponsors, with government agencies providing the most support. Study findings highlight the need for sponsorship transparency and the role of government as a leading supporter of studies that underpin CPSTF recommendations for improving public health. |
Healthier food and beverage interventions in schools: Four Community Guide systematic reviews
Wethington HR , Finnie RKC , Buchanan LR , Okasako-Schmucker DL , Mercer SL , Merlo C , Wang Y , Pratt CA , Ochiai E , Glanz K . Am J Prev Med 2020 59 (1) e15-e26 CONTEXT: Healthy eating during childhood is important for optimal growth and helps reduce the risk of obesity, which has potentially serious health consequences. Changing the school food environment may offer one way to improve students' dietary intake. This manuscript reports 4 Community Guide systematic reviews examining the effectiveness of interventions in schools promoting healthy eating and weight. EVIDENCE ACQUISITION: School obesity prevention programs aiming to improve diet were identified from a 2013 Agency for Health Care Research and Quality systematic review and an updated search (August 2012-January 4, 2017). In 2017-2018, Community Guide systematic review methods were used to assess effectiveness as determined by dietary behavior and weight changes. EVIDENCE SYNTHESIS: Interventions improving school meals or offering fruits and vegetables (n=27 studies) are considered effective. Evidence is insufficient to determine the effectiveness of interventions supporting healthier snack foods and beverages outside of school meal programs given inconsistent findings (n=13 studies). Multicomponent interventions to increase availability of healthier foods and beverages are considered effective. These interventions must include 1 component from school meals or fruit and vegetable programs and interventions supporting healthier snack foods and beverages (n=12 studies). There is insufficient evidence to determine the effectiveness of interventions to increase water access because only 2 studies met inclusion criteria. CONCLUSIONS: A total of 2 school-based dietary interventions have favorable effects for improving dietary habits and modest effects for improving or maintaining weight. More evidence is needed regarding interventions with insufficient findings. These reviews may inform researchers and school administrators about healthy eating and obesity prevention interventions. |
Economics of multicomponent interventions to increase breast, cervical, and colorectal cancer screening: A Community Guide Systematic Review
Mohan G , Chattopadhyay SK , Ekwueme DU , Sabatino SA , Okasako-Schmucker DL , Peng Y , Mercer SL , Thota AB . Am J Prev Med 2019 57 (4) 557-567 CONTEXT: The Community Preventive Services Task Force recently recommended multicomponent interventions to increase breast, cervical, and colorectal cancer screening based on strong evidence of effectiveness. This systematic review examines the economic evidence to guide decisions on the implementation of these interventions. EVIDENCE ACQUISITION: A systematic literature search for economic evidence was performed from January 2004 to January 2018. All monetary values were reported in 2016 US dollars, and the analysis was completed in 2018. EVIDENCE SYNTHESIS: Fifty-three studies were included in the body of evidence from a literature search yield of 8,568 total articles. For multicomponent interventions to increase breast cancer screening, the median intervention cost per participant was $26.69 (interquartile interval [IQI]=$3.25, $113.72), and the median incremental cost per additional woman screened was $147.64 (IQI=$32.92, $924.98). For cervical cancer screening, the median costs per participant and per additional woman screened were $159.80 (IQI=$117.62, $214.73) and $159.49 (IQI=$64.74, $331.46), respectively. Two studies reported incremental cost per quality-adjusted life year gained of $748 and $33,433. For colorectal cancer screening, the median costs per participant and per additional person screened were $36.63 (IQI=$7.70, $139.23) and $582.44 (IQI=$91.10, $1,452.12), respectively. Two studies indicated a decline in incremental cost per quality-adjusted life year gained of $1,651 and $3,817. CONCLUSIONS: Multicomponent interventions to increase cervical and colorectal cancer screening were cost effective based on a very conservative threshold. Additionally, multicomponent interventions for colorectal cancer screening demonstrated net cost savings. Cost effectiveness for multicomponent interventions to increase breast cancer screening could not be determined owing to the lack of studies reporting incremental cost per quality-adjusted life year gained. Future studies estimating this outcome could assist implementers with decision making. |
Community Guide Cardiovascular Disease Economic Reviews: Tailoring methods to ensure utility of findings
Chattopadhyay SK , Jacob V , Mercer SL , Hopkins DP , Elder RW , Jones CD . Am J Prev Med 2017 53 S155-s163 The Community Preventive Services Task Force recommended five interventions for cardiovascular disease prevention between 2012 and 2015. Systematic economic reviews of these interventions faced challenges that made it difficult to generate meaningful policy and programmatic conclusions. This paper describes the methods used to assess, synthesize, and evaluate the economic evidence to generate reliable and useful economic conclusions and address the comparability of economic findings across interventions. Specifically, steps were taken to assess completeness of data and identify the components and drivers of cost and benefit. Except for the intervention cost of self-measured blood pressure monitoring intervention, either alone or with patient support, all cost and benefit estimates were standardized as per patient per year. When possible, intermediate outcomes were converted to quality-adjusted life year. Differences within and between interventions were considered to generate economic conclusions and inform their comparability. The literature search period varied among interventions. This analysis was completed in 2016. Although team-based care, self-measured blood pressure monitoring with patient support, and self-measured blood pressure monitoring within team-based care were found to be cost effective, their cost-effectiveness estimates were not comparable because of differences in the intervention characteristics. Lack of enough data or incomplete information made it difficult to reach an overall economic finding for the other interventions. The Community Guide methods discussed here may help others conducting systematic economic reviews of public health interventions to respond to challenges with the synthesis of evidence and provide useful findings for public health decision makers. |
Practice-based evidence in Community Guide Systematic Reviews
Vaidya N , Thota AB , Proia KK , Jamieson S , Mercer SL , Elder RW , Yoon P , Kaufmann R , Zaza S . Am J Public Health 2017 107 (3) e1-e8 OBJECTIVES: To assess the relative contributions and quality of practice-based evidence (PBE) and research-based evidence (RBE) in The Guide to Community Preventive Services (The Community Guide). METHODS: We developed operational definitions for PBE and RBE in which the main distinguishing feature was whether allocation of participants to intervention and comparison conditions was under the control of researchers (RBE) or not (PBE). We conceptualized a continuum between RBE and PBE. We then categorized 3656 studies in 202 reviews completed since The Community Guide began in 1996. RESULTS: Fifty-four percent of studies were PBE and 46% RBE. Community-based and policy reviews had more PBE. Health care system and programmatic reviews had more RBE. The majority of both PBE and RBE studies were of high quality according to Community Guide scoring methods. CONCLUSIONS: The inclusion of substantial PBE in Community Guide reviews suggests that evidence of adequate rigor to inform practice is being produced. This should increase stakeholders' confidence that The Community Guide provides recommendations with real-world relevance. Limitations in some PBE studies suggest a need for strengthening practice-relevant designs and external validity reporting standards. (Am J Public Health.

Mass media health communication campaigns combined with health-related product distribution: a Community Guide Systematic Review
Robinson MN , Tansil KA , Elder RW , Soler RE , Labre MP , Mercer SL , Eroglu D , Baur C , Lyon-Daniel K , Fridinger F , Sokler LA , Green LW , Miller T , Dearing JW , Evans WD , Snyder LB , Kasisomayajula Viswanath K , Beistle DM , Chervin DD , Bernhardt JM , Rimer BK . Am J Prev Med 2014 47 (3) 360-371 CONTEXT: Health communication campaigns including mass media and health-related product distribution have been used to reduce mortality and morbidity through behavior change. The intervention is defined as having two core components reflecting two social marketing principles: (1) promoting behavior change through multiple communication channels, one being mass media, and (2) distributing a free or reduced-price product that facilitates adoption and maintenance of healthy behavior change, sustains cessation of harmful behaviors, or protects against behavior-related disease or injury. EVIDENCE ACQUISITION: Using methods previously developed for the Community Guide, a systematic review (search period, January 1980-December 2009) was conducted to evaluate the effectiveness of health communication campaigns that use multiple channels, including mass media, and distribute health-related products. The primary outcome of interest was use of distributed health-related products. EVIDENCE SYNTHESIS: Twenty-two studies that met Community Guide quality criteria were analyzed in 2010. Most studies showed favorable behavior change effects on health-related product use (a median increase of 8.4 percentage points). By product category, median increases in desired behaviors ranged from 4.0 percentage points for condom promotion and distribution campaigns to 10.0 percentage points for smoking-cessation campaigns. CONCLUSIONS: Health communication campaigns that combine mass media and other communication channels with distribution of free or reduced-price health-related products are effective in improving healthy behaviors. This intervention is expected to be applicable across U.S. demographic groups, with appropriate population targeting. The ability to draw more specific conclusions about other important social marketing practices is constrained by limited reporting of intervention components and characteristics. |
Economics of mass media health campaigns with health-related product distribution: a Community Guide Systematic Review
Jacob V , Chattopadhyay SK , Elder RW , Robinson MN , Tansil KA , Soler RE , Labre MP , Mercer SL . Am J Prev Med 2014 47 (3) 348-359 CONTEXT: The objective of this systematic review was to determine the costs, benefits, and overall economic value of communication campaigns that included mass media and distribution of specified health-related products at reduced price or free of charge. EVIDENCE ACQUISITION: Economic evaluation studies from a literature search from January 1980 to December 2009 were screened and abstracted following systematic economic review methods developed by The Community Guide. Data were analyzed in 2011. EVIDENCE SYNTHESIS: The economic evidence was grouped and assessed by type of product distributed and health risk addressed. A total of 15 evaluation studies were included in the economic review, involving campaigns promoting the use of child car seats or booster seats, pedometers, condoms, recreational safety helmets, and nicotine replacement therapy. CONCLUSIONS: Economic merits of the intervention could not be determined for health communication campaigns associated with use of recreational helmets, child car seats, and pedometers, primarily because available economic information and analyses were incomplete. There is some evidence that campaigns with free condom distribution to promote safer sex practices were cost-effective among high-risk populations and the cost per quit achieved in campaigns promoting tobacco cessation with nicotine replacement therapy products may translate to a cost per quality-adjusted life-year less than $50,000. Many interventions were publicly funded trials or programs, and the failure to properly evaluate their economic cost and benefit is a serious gap in the science and practice of public health. |
Guiding the way to public health improvement: exploring the connections between the Community Guide's evidence-based interventions and health department accreditation standards
Mercer SL , Banks SM , Verma P , Fisher JS , Corso LC , Carlson V . J Public Health Manag Pract 2014 20 (1) 104-10 CONTEXT: Recent years have seen rising interest in initiatives that focus on public health improvement. This includes support for accreditation of public health departments-administered by the Public Health Accreditation Board (PHAB)-and increasing expectations that health departments should use evidence-based programs, services, and policies (interventions) such as those described in The Guide to Community Preventive Services (The Community Guide). OBJECTIVE: This project was initiated to explore the potential connections between Community Guide interventions and PHAB domains, standards, and measures. DESIGN: The project team focused on developing a Crosswalk tool to assist health departments in identifying evidence-based interventions from The Community Guide whose implementation could help document conformity with PHAB domains, standards, and measures. All Community Preventive Services Task Force-recommended interventions were reviewed to determine whether they reflect the intent and requirements of the PHAB standards and measures. MAIN OUTCOME MEASURES: Three types of connections were defined through which Community Guide interventions could be relevant to the required documentation for a PHAB measure. All instances of these connections were identified and included in the Crosswalk. RESULTS: The Crosswalk tool consists of 2 tables. The first table cross-references individual PHAB domains, standards, and measures with interventions from The Community Guide that could help provide documentation for accreditation. The second table can help accreditation preparation staff to engage with program staff. It is searchable by Community Guide topic, identifying the PHAB measures that relate to each Community Guide intervention within that topic. The type, location, and extent of connections between Community Guide interventions and PHAB domains, standards, and measures are presented and discussed. CONCLUSIONS: Tools such as the Crosswalk can be instrumental in advancing the use of evidence-based interventions in public health practice. |
Navigating the road ahead: public health challenges and the Interactive Systems Framework for Dissemination and Implementation
Noonan RK , Wilson KM , Mercer SL . Am J Community Psychol 2012 50 572-80 Public health is currently faced with an array of critical challenges and disconnects. Research and evaluation have identified a number of evidence-based strategies for effecting behavior change at individual, group, organizational, and environmental levels, all of which hold promise for leading to substantial reductions in morbidity and mortality, and increased quality of life. Unfortunately, there is huge variability across the public health system in awareness of the value of using evidence to inform decision making, let alone in capacity to locate, assess, compare, select, justify, adapt, implement, and evaluate evidence-based strategies, or to participate in building the evidence base for practice-based innovations. As a result, many communities may not be benefitting from research-tested and practice-based strategies that could help them to meet their public health goals more efficiently and effectively. CDC's Interactive Systems Framework for Dissemination and Implementation (ISF), released in 2008, was designed to help close this gap between research and practice. This commentary identifies the ways in which the ISF framework is useful in addressing the research practice gap; revisits the elements of the framework that have continued to guide research and practice in fruitful ways; and highlights areas that need further development to meet current public health challenges. |
Effectiveness of interventions to increase screening for breast, cervical, and colorectal cancers: nine updated systematic reviews for the Guide to Community Preventive Services
Sabatino SA , Lawrence B , Elder R , Mercer SL , Wilson KM , Devinney B , Melillo S , Carvalho M , Taplin S , Bastani R , Rimer BK , Vernon SW , Melvin CL , Taylor V , Fernandez M , Glanz K . Am J Prev Med 2012 43 (1) 97-118 CONTEXT: Screening reduces mortality from breast, cervical, and colorectal cancers. The Guide to Community Preventive Services previously conducted systematic reviews on the effectiveness of 11 interventions to increase screening for these cancers. This article presents results of updated systematic reviews for nine of these interventions. EVIDENCE ACQUISITION: Five databases were searched for studies published during January 2004-October 2008. Studies had to (1) be a primary investigation of one or more intervention category; (2) be conducted in a country with a high-income economy; (3) provide information on at least one cancer screening outcome of interest; and (4) include screening use prior to intervention implementation or a concurrent group unexposed to the intervention category of interest. Forty-five studies were included in the reviews. EVIDENCE SYNTHESIS: Recommendations were added for one-on-one education to increase screening with fecal occult blood testing (FOBT) and group education to increase mammography screening. Strength of evidence for client reminder interventions to increase FOBT screening was upgraded from sufficient to strong. Previous findings and recommendations for reducing out-of-pocket costs (breast cancer screening); provider assessment and feedback (breast, cervical, and FOBT screening); one-on-one education and client reminders (breast and cervical cancer screening); and reducing structural barriers (breast cancer and FOBT screening) were reaffirmed or unchanged. Evidence remains insufficient to determine effectiveness for the remaining screening tests and intervention categories. CONCLUSIONS: Findings indicate new and reaffirmed interventions effective in promoting recommended cancer screening, including colorectal cancer screening. Findings can be used in community and healthcare settings to promote recommended care. Important research gaps also are described. |
The effectiveness of group-based comprehensive risk-reduction and abstinence education interventions to prevent or reduce the risk of adolescent pregnancy, human immunodeficiency virus, and sexually transmitted infections: two systematic reviews for the Guide to Community Preventive Services
Chin HB , Sipe TA , Elder R , Mercer SL , Chattopadhyay SK , Jacob V , Wethington HR , Kirby D , Elliston DB , Griffith M , Chuke SO , Briss SC , Ericksen I , Galbraith JS , Herbst JH , Johnson RL , Kraft JM , Noar SM , Romero LM , Santelli J , Community Preventive Services Task Force . Am J Prev Med 2012 42 (3) 272-94 CONTEXT: Adolescent pregnancy, HIV, and other sexually transmitted infections (STIs) are major public health problems in the U.S. Implementing group-based interventions that address the sexual behavior of adolescents may reduce the incidence of pregnancy, HIV, and other STIs in this group. EVIDENCE ACQUISITION: Methods for conducting systematic reviews from the Guide to Community Preventive Services were used to synthesize scientific evidence on the effectiveness of two strategies for group-based behavioral interventions for adolescents: (1) comprehensive risk reduction and (2) abstinence education on preventing pregnancy, HIV, and other STIs. Effectiveness of these interventions was determined by reductions in sexual risk behaviors, pregnancy, HIV, and other STIs and increases in protective sexual behaviors. The literature search identified 6579 citations for comprehensive risk reduction and abstinence education. Of these, 66 studies of comprehensive risk reduction and 23 studies of abstinence education assessed the effects of group-based interventions that address the sexual behavior of adolescents, and were included in the respective reviews. EVIDENCE SYNTHESIS: Meta-analyses were conducted for each strategy on the seven key outcomes identified by the coordination team-current sexual activity; frequency of sexual activity; number of sex partners; frequency of unprotected sexual activity; use of protection (condoms and/or hormonal contraception); pregnancy; and STIs. The results of these meta-analyses for comprehensive risk reduction showed favorable effects for all of the outcomes reviewed. For abstinence education, the meta-analysis showed a small number of studies, with inconsistent findings across studies that varied by study design and follow-up time, leading to considerable uncertainty around effect estimates. CONCLUSIONS: Based on these findings, group-based comprehensive risk reduction was found to be an effective strategy to reduce adolescent pregnancy, HIV, and STIs. No conclusions could be drawn on the effectiveness of group-based abstinence education. |
Methods for conducting community guide systematic reviews of evidence on effectiveness and economic efficiency of group-based behavioral interventions to prevent adolescent pregnancy, human immunodeficiency virus, and other sexually transmitted infections: comprehensive risk reduction and abstinence education
Sipe TA , Chin HB , Elder R , Mercer SL , Chattopadhyay SK , Jacob V , Community Preventive Services Task Force . Am J Prev Med 2012 42 (3) 295-303 This paper describes methods used to conduct systematic reviews and meta-analyses and economic reviews of group-based behavioral interventions for adolescents to prevent pregnancy, HIV, and other sexually transmitted infections.

In addition, identification of potential harms and benefits, applicability of results, barriers to implementation, and research gaps are described. |
Scientific evidence and policy change: lowering the legal blood alcohol limit for drivers to 0.08% in the USA
Sleet DA , Mercer SL , Cole KH , Shults RA , Elder RW , Nichols JL . Glob Health Promot 2011 18 (1) 23-26, 115, 150 The United States (US) Centers for Disease Control and Prevention (CDC), and key partners conducted a systematic review of the effectiveness of 0.08% blood alcohol concentration (BAC) laws on alcohol-related traffic mortality. Review findings of strong evidence of effectiveness were presented by partners during US Congressional hearings contributing to the passage of a bill requiring states to lower the legal BAC limit to 0.08% (80 mg of alcohol/100 ml of blood) or lose a portion of their federal highway funds. The bill was signed into law, making 0.08 the new national standard. Extensive and targeted dissemination of the evidence and recommendations to key stakeholders and partners built support for policy change at the state level. |
Translating evidence into policy: lessons learned from the case of lowering the legal blood alcohol limit for drivers
Mercer SL , Sleet DA , Elder RW , Cole KH , Shults RA , Nichols JL . Ann Epidemiol 2010 20 (6) 412-20 This case study examines the translation of evidence on the effectiveness of laws to reduce the blood alcohol concentration (BAC) of drivers into policy. It was reconstructed through discussions among individuals involved in the processes as well as a review of documentation and feedback on oral presentations. The Centers for Disease Control and Prevention collaborated extensively with federal and non-federal partners and stakeholders in conducting a rigorous systematic review, using the processes of the Guide to Community Preventive Services to evaluate the body of empirical evidence on 0.08% BAC laws. The timely dissemination of the findings and related policy recommendations-made by the independent Task Force on Community Preventive Services-to Congress very likely contributed to the inclusion of strong incentives to States to adopt 0.08 BAC laws by October 2003. Subsequent dissemination to partners and stakeholders informed decision-making about support for state legislative and policy action. This case study suggests the value of: clearly outlining the relationships between health problems, interventions and outcomes; systematically assessing and synthesizing the evidence; using a credible group and rigorous process to assess the evidence; having an impartial body make specific policy recommendations on the basis of the evidence; being ready to capitalize in briefly opening policy windows; engaging key partners and stakeholders throughout the production and dissemination of the evidence and recommendations; undertaking personalized, targeted and compelling dissemination of the evidence and recommendations; involving multiple stakeholders in encouraging uptake and adherence of policy recommendations; and addressing sustainability. These lessons learned may help others working to translate evidence into policy. |
