RESUMEN
OBJECTIVE: Disparities by race and socioeconomic status persist in pediatric asthma morbidity, mortality, and treatment. Improving parent/provider communication and parents' asthma-management confidence may result in better asthma control in vulnerable populations. The Merck Childhood Asthma Network, Inc. funded an initiative to implement medical-social care coordination to improve asthma outcomes at sites in four low-income, urban communities (Los Angeles, CA; Philadelphia, PA; Chicago, IL; and San Juan, PR.) As part of a cross-site evaluation of this effort, pre- post-program changes in parents' reports of asthma care and management were assessed. METHODS: Across sites, 805 parents or other caregivers responded to a baseline survey that was repeated one year later following their child's participation in care coordination. Parents' asthma-management confidence, as well as their perceptions of provider access, trust, and communication, were measured with Likert scales. Linear mixed models were used to assess improvement in these variables, across and within sites, adjusting for sociodemographics. RESULTS: Pooled across sites, the adjusted mean estimate for all outcomes showed a significant improvement (p <.05) from baseline to follow-up. Knowledge and Between-Provider Communication improved significantly (p <.05) within all four sites; Access improved significantly in Chicago, Philadelphia, and Puerto Rico; Trust improved significantly in Chicago, Los Angeles, and Philadelphia; and Patient-Provider Communication improved significantly in Philadelphia only. CONCLUSION: Pediatric asthma care coordination, as implemented variously in diverse settings, was associated with improvement in parents' perceptions of asthma care and self-reported asthma-management knowledge and confidence. This positive impact on parents may help sustain care coordination's impact on children.

OBJECTIVES: To assess the effect of care coordination on asthma outcomes among children in underserved urban communities. METHODS: We enrolled children, most of whom had very poorly or not well-controlled asthma, in medical-social care coordination programs in Los Angeles, California; Chicago, Illinois; Philadelphia, Pennsylvania; and San Juan, Puerto Rico in 2011 to 2014. Participants (n = 805; mean age = 7 years) were 60% male, 50% African American, and 42% Latino. We assessed asthma symptoms and health care utilization via parent interview at baseline and 12 months. To prevent overestimation of intervention effects, we constructed a comparison group using bootstrap resampling of matched control cases from previous pediatric asthma trials. RESULTS: At follow-up, intervention participants had 2.2 fewer symptom days per month (SD = 0.3; P < .01) and 1.9 fewer symptom nights per month (SD = 0.35; P < .01) than did the comparison group. The relative risk in the past year associated with the intervention was 0.63 (95% confidence interval [CI] = 0.45, 0.89) for an emergency department visit and 0.69 (95% CI = 0.47, 1.01) for hospitalization. CONCLUSIONS: Care coordination may improve pediatric asthma symptom control and reduce emergency department visits. POLICY IMPLICATIONS: Expanding third-party reimbursement for care coordination services may help reduce pediatric asthma disparities.

Adaptation of evidence-based interventions upon implementation into new practice settings is universal, yet poorly understood. During a cross-site evaluation of the implementation of a proven intervention for pediatric asthma care coordination into 4 resource-challenged settings, we conducted in-depth interviews with site representatives, who reported how and why they modified intervention components. Interview notes were coded for themes. We focused on a single theme from a respondent who described the adaptation process as "backing" the intervention into ongoing services; we found evidence of a similar process at other sites. We labeled this process "retrofitting" to signify adaptation that consists of altering existing services to align with intervention components, rather than modifying the intervention to fit a new setting. Advantages of retrofitting may include allowing organizations to keep what works, capitalizing on existing support for program activities, elevating the role of local knowledge, and potentially promoting the sustainability of effective innovations.

INTRODUCTION: As part of a cross-site evaluation of the implementation of an evidence-based intervention for pediatric asthma care coordination into low-income communities, we sought to understand the factors that influenced the programs' expected sustainability of the programs after external funding ended. METHODS: We administered the Center for Public Health Systems Science's Program Sustainability Assessment Tool, a 40-item instrument assessing 8 domains of sustainability capacity, to 12 key informants across 4 program sites. We developed open-ended probes for each domain. We examined patterns in site-specific and overall domain scores, and coded qualitative data to identify challenges and strategies in each domain. RESULTS: Across sites, the domains of program evaluation (cross-site mean, 5.4 on a scale of 1-7) and program adaptation (mean, 5.2) had the highest ratings (indicating a strong finding during program evaluation) and funding stability had the lowest rating (mean, 2.7). Scores varied most across sites in the domains of strategic planning (SD, 0.9) and funding stability (SD, 0.9). Qualitative data revealed key challenges, including how implementation difficulties and externally led implementation can impede planning for sustainability. Program leaders discussed multiple strategies for enhancing capacity within each domain, including capitalizing on the interconnectedness of all domains, such as using evaluation and communication strategies to bolster internal political support throughout the implementation process. CONCLUSION: Findings indicating weak and strong domains were consistent with previous findings of studies that used the Program Sustainability Assessment Tool. The addition of qualitative probes yielded detailed data describing capacity strengths, weaknesses, and strategies to increase the likelihood that programs are sustained.

Asthma affects 7.1 million children in the United States, disproportionately burdening African American and Latino children. Barriers to asthma control include insufficient patient education and fragmented care. Care coordination represents a compelling approach to improve quality of care and address disparities in asthma. The sites of The Merck Childhood Asthma Network Care Coordination Programs implemented different models of care coordination to suit specific settings-school district, clinic or health care system, and community-and organizational structures. A variety of qualitative data sources were analyzed to determine the role setting played in the manifestation of care coordination at each site. There were inherent strengths and challenges of implementing care coordination in each of the settings, and each site used unique strategies to deliver their programs. The relationship between the lead implementing unit and entities that provided (1) access to the priority population and (2) clinical services to program participants played a critical role in the structure of the programs. The level of support and infrastructure provided by these entities to the lead implementing unit influenced how participants were identified and how asthma care coordinators were integrated into the clinical care team.

INTRODUCTION: Although several studies suggest that drinking water may help prevent obesity, no US studies have examined the effect of school drinking water provision and promotion on student beverage intake. We assessed the acceptability, feasibility, and outcomes of a school-based intervention to improve drinking water consumption among adolescents. METHODS: The 5-week program, conducted in a Los Angeles middle school in 2008, consisted of providing cold, filtered drinking water in cafeterias; distributing reusable water bottles to students and staff; conducting school promotional activities; and providing education. Self-reported consumption of water, nondiet soda, sports drinks, and 100% fruit juice was assessed by conducting surveys among students (n = 876), preintervention and at 1 week and 2 months postintervention, from the intervention school and the comparison school. Daily water (in gallons) distributed in the cafeteria during the intervention was recorded. RESULTS: After adjusting for sociodemographic characteristics and baseline intake of water at school, the odds of drinking water at school were higher for students at the intervention school than students at the comparison school. Students from the intervention school had higher adjusted odds of drinking water from fountains and from reusable water bottles at school than students from the comparison school. Intervention effects for other beverages were not significant. CONCLUSION: Provision of filtered, chilled drinking water in school cafeterias coupled with promotion and education is associated with increased consumption of drinking water at school. A randomized controlled trial is necessary to assess the intervention's influence on students' consumption of water and sugar-sweetened beverages, as well as obesity-related outcomes.

Care coordination programs have been used to address chronic illnesses, including childhood asthma, but primarily via practice-based models. An alternative approach employs community-based care coordinators who bridge gaps between families, health care providers, and support services. Merck Childhood Asthma Network, Inc. (MCAN) sites developed community-based care coordination approaches for childhood asthma. Using a community-based care coordination logic model, programs at each site are described along with program operational statistics. Four sites used three to four community health workers (CHWs) to provide care coordination, whereas one site used five school-based asthma nurses. This school-based site had the highest caseload (82.5 per year), but program duration was 3 months with 4 calls or visits. Other sites averaged fewer cases (35 to 61 per CHW per year), but families received more (7 to 17) calls or visits over a year. Retention was 43% to 93% at 6 months and 24% to 75% at 12 months. Pre-post cross-site data document changes in asthma management behaviors and outcomes. After program participation, 93% to 100% of caregivers had confidence in controlling their child's asthma, 85% to 92% had taken steps to reduce triggers, 69% to 100% had obtained an asthma action plan, and 46% to 100% of those with moderate to severe asthma reported appropriate use of controller medication. Emergency department visits for asthma decreased by 36% to 63%, and asthma-related hospitalizations declined by 26% to 78%. More than three fourths had fewer school absences. In conclusion, MCAN community-based care coordination programs improved management behaviors and decreased morbidity across all sites.

Partnerships have taken on added importance in recent years because of their critical role in addressing complex public health problems and translating evidence-based practices to real-world settings. The Merck Childhood Asthma Network, Inc. initiative recognized the importance of partnerships in achieving the program's goals. In this article, case studies of the five Merck Childhood Asthma Network program sites describe the role of partnerships in the development and evolution of the program and its interventions. Three key factors contributed to the success of the partnerships: having common organizational goals, considering context in the selection and engagement of partners, and ensuring that each partnership benefited from the alliance. Over the 4-year program period, all five partnerships evolved, matured, and had an established goal to maintain collaboration.

The Merck Childhood Asthma Network (MCAN) initiative selected five sites (New York City, Puerto Rico, Chicago, Los Angeles, and Philadelphia) to engage in translational research to adapt evidence-based interventions (EBIs) to improve childhood asthma outcomes. The authors summarize the sites' experience by describing criteria defining the fidelity of translation, community contextual factors serving as barriers or enablers to fidelity, types of adaptation conducted, and strategies used to balance contextual factors and fidelity in developing a "best fit" for EBIs in the community. A conceptual model captures important structural and process-related factors and helps frame lessons learned. Site implementers and intervention developers reached consensus on qualitative rankings of the levels of fidelity of implementation for each of the EBI core components: low fidelity, adaptation (major vs. minor), or high fidelity. MCAN sites were successful in adapting core EBI components based on their understanding of structural and other contextual barriers and enhancers in their communities. Although the sites varied regarding both the EBI components they implemented and their respective levels of fidelity, all sites observed improvement in asthma outcomes. Our collective experiences of adapting and implementing asthma EBIs highlight many of the factors affecting translation of evidenced-based approaches to chronic disease management in real community settings.

This article reports on an evaluation of the Merck Childhood Asthma Network, Inc. (MCAN) initiative using pooled cross-site data on patient-reported outcomes pre- and postintervention to quantify the changes experienced by children in five program sites supported by the network. The results show a consistent pattern of improvement across all measured outcomes, including symptoms, hospital and emergency department use, school absences, and caregiver confidence. Children who started with uncontrolled asthma experienced larger improvements than children with controlled asthma at baseline. However, even considering the significant gains made by children with uncontrolled asthma at baseline, after 12 months, most of the outcomes for these children were significantly worse than the 12-month outcomes for children with controlled asthma at baseline. The evaluation of the MCAN initiative offers a model that can be used in cases where resources must be balanced between evaluation and delivering services to children. The design process and results from the common survey instrument provide information for future initiatives seeking to translate evidence-based interventions in a community-based setting.

INTRODUCTION: Concerns about the influence of sugar-sweetened beverage consumption on obesity have led experts to recommend that water be freely available in schools. We explored perceptions about the adequacy of drinking water provision in a large California school district to develop policies and programs to encourage student water consumption. METHODS: From March to September 2007, we used semistructured interviews to ask 26 California key stakeholders - including school administrators and staff, health and nutrition agency representatives, and families - about school drinking water accessibility; attitudes about, facilitators of, and barriers to drinking water provision; and ideas for increasing water consumption. Interviews were analyzed to determine common themes. RESULTS: Although stakeholders said that water was available from school drinking fountains, they expressed concerns about the appeal, taste, appearance, and safety of fountain water and worried about the affordability and environmental effect of bottled water sold in schools. Stakeholders supported efforts to improve free drinking water availability in schools, but perceived barriers (eg, cost) and mistaken beliefs that regulations and beverage contracts prohibit serving free water may prevent schools from doing so. Some schools provide water through cold-filtered water dispensers and self-serve water coolers. CONCLUSION: This is the first study to explore stakeholder perceptions about the adequacy of drinking water in US schools. Although limited in scope, our study suggests that water available in at least some schools may be inadequate. Collaborative efforts among schools, communities, and policy makers are needed to improve school drinking water provision.

OBJECTIVE: Human papillomavirus (HPV) immunization rates among US adolescents are low. Missed opportunities (MOs) for HPV vaccination are common. School-based health centers (SBHCs) have potential to boost HPV vaccination, but their role in addressing MOs has not been examined. METHODS: We implemented a multicomponent intervention, consisting of 3 immunization process workflow modifications combined with provider performance feedback, in 2 Los Angeles area SBHCs and conducted a pre/post evaluation of MOs. Our primary outcome was SBHC-based MOs for HPV vaccination during all visits, including visits for confidential reproductive health care (ie, confidential visits). Secondary outcomes were MOs for meningococcal (MenACWY) and influenza vaccination during visits for nonconfidential care. RESULTS: MOs for HPV vaccination decreased during all visit types from the baseline to the intervention period (82.3% to 46.1%; adjusted risk ratio [RR] = 0.558, P < .0001). The rate decrease appeared to be greater during physical examination visits than confidential visits (83.4% to 31.6% vs 98.7% to 70.4%, respectively). MOs for MenACWY (74.5% to 35.0%; adjusted RR = 0.47, P < .0001) and influenza (86.7% to 69.3%; adjusted RR = 0.792, P < .0001) vaccination also decreased during nonconfidential visits. Vaccine refusal was the most frequently documented reason for HPV vaccine MOs during both physical examination and confidential visits. CONCLUSIONS: A pragmatic, multicomponent SBHC intervention reduced MOs for HPV vaccination during all visit types. MOs for MenACWY and influenza vaccination also decreased during nonconfidential visits. Findings suggest that practice-level improvements in SBHCs can improve delivery of HPV and other adolescent vaccines.

The present issue contains one of the first studies published in Health Psychology-by Resnicow and colleagues-that uses elements of community-based participatory research (CBPR) (Resnicow et al., 2009). The authors engaged community partners (three health maintenance organizations or HMOs) to develop and implement a fruit and vegetable promotion intervention (Tolsma et al., 2009). African American HMO patients (the intervention targets) participated in formative work (i.e., focus groups) on survey items and intervention content and in survey pilot testing. A diverse group of researcher and nonresearcher expert stakeholders (e.g., African American health plan staff; consultants with expertise in Black identity theory, on which the intervention was based) was engaged in major project decisions regarding the measures and intervention design.

Using a community-based participatory research approach, we explored adolescent, parent, and community stakeholder perspectives on barriers to healthy eating and physical activity, and intervention ideas to address adolescent obesity. We conducted 14 adolescent focus groups (n = 119), 8 parent focus groups (n = 63), and 28 interviews with community members (i.e., local experts knowledgeable about youth nutrition and physical activity). Participants described ecological and psychosocial barriers in neighborhoods (e.g., lack of accessible nutritious food), in schools (e.g., poor quality of physical education), at home (e.g., sedentary lifestyle), and at the individual level (e.g., lack of nutrition knowledge). Participants proposed interventions such as nutrition classes for families, addition of healthy school food options that appeal to students, and non-competitive physical education activities. Participants supported health education delivered by students. Findings demonstrate that community-based participatory research is useful for revealing potentially feasible interventions that are acceptable to community members.

Few evidence-based school obesity-prevention programs are disseminated. We used community-based participatory research principles to disseminate an evidence-based middle-school obesity-prevention program, Students for Nutrition and eXercise (SNaX), to a large, primarily Latino, school district. In the 2014-2015 school year, we trained a district "champion" to provide training and technical assistance to schools and supplied print- and web-based materials (www.snaxinschools.org). In one district region, 18 of 26 schools agreed to participate. We evaluated the dissemination process using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. All 18 schools implemented at least one SNaX component. Of 6,410 students who attended an informational session, 1,046 registered and 472 were selected to be Student Advocates, of whom 397 attended at least one meeting. Of 60 activities observed across schools, 77% were conducted with fidelity, but local resource constraints limited most activities to a relatively small number of Student Advocates (vs. the entire student body). Qualitative data from 46 school staff and 187 students indicated positive attitudes about the program. Teachers suggested that SNaX be implemented as part of the curriculum. In the 2015-2016 school year, 6 of the original schools continued to implement SNaX, and the champion trained 94 teachers from 57 schools districtwide. Cafeteria servings overall and fruit and vegetable servings, the primary outcomes, did not increase in SNaX schools versus matched-comparison schools. Our mixed-methods evaluation of SNaX showed acceptability and fidelity, but not effectiveness. Effectiveness may be improved by providing technical assistance to community stakeholders on how to tailor core intervention components while maintaining fidelity.

OBJECTIVE: Sugar-sweetened beverages (SSBs) are key contributors to obesity among youth. We investigated associations among parental and home-related factors (parental attitudes and consumption; home availability) regarding 3 types of SSBs-soda, sports drinks, and fruit-flavored drinks-with consumption of each type of SSB in a general school-based sample of adolescents. METHODS: Data were collected across 3 school semesters, from 2009 to 2011. A total of 1313 seventh grade student-parent dyads participated. Students completed in-class surveys across 9 schools in a large Los Angeles school district; their parents completed telephone interviews. Youth were asked about their SSB consumption (soda, sports drinks, and fruit-flavored drinks), and parents were asked about their attitudes, consumption, and home availability of SSBs. RESULTS: We estimated expected rates of youth SSB consumption for hypothetical parents at very low (5th) and very high (95th) percentiles for home/parental risk factors (ie, they consumed little, had negative attitudes, and did not keep SSBs in the home; or they consumed a lot, had positive attitudes, and did keep SSBs in the home). Youth of lower-risk parents (at the 5th percentile) were estimated to drink substantially less of each type of beverage than did youth of higher-risk parents (at the 95th percentile). For example, youth with higher-risk parents averaged nearly double the SSB consumption of youth of lower-risk parents (2.77 vs 1.37 glasses on the previous day; overall model significance F22,1312 = 3.91, P < .001). CONCLUSIONS: Results suggest a need to focus on parental and home environmental factors when intervening to reduce youths' SSB consumption.

OBJECTIVE: To examine the cost and cost-effectiveness of implementing Students for Nutrition and eXercise (SNaX), a 5-week middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. METHODS: Five intervention and 5 control middle schools (mean enrollment, 1520 students) from the Los Angeles Unified School District participated in a randomized controlled trial of SNaX. Acquisition costs for materials and time and wage data for employees involved in implementing the program were used to estimate fixed and variable costs. Cost-effectiveness was determined using the ratio of variable costs to program efficacy outcomes. RESULTS: The costs of implementing the program over 5 weeks were $5433.26 per school in fixed costs and $2.11 per student in variable costs, equaling a total cost of $8637.17 per school, or $0.23 per student per day. This investment yielded significant increases in the proportion of students served fruit and lunch and a significant decrease in the proportion of students buying snacks. The cost-effectiveness of the program, per student over 5 weeks, was $1.20 per additional fruit served during meals, $8.43 per additional full-priced lunch served, $2.11 per additional reduced-price/free lunch served, and $1.69 per reduction in snacks sold. CONCLUSIONS: SNaX demonstrated the feasibility and cost-effectiveness of a middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. Its cost is modest and unlikely to be a significant barrier to adoption for many schools considering its implementation.

OBJECTIVES: This study examined the long-term effects on BMI of a randomized controlled trial of Students for Nutrition and Exercise, a 5-week, middle school-based obesity prevention intervention combining school-wide environmental changes, encouragement to eat healthy school cafeteria foods, and peer-led education and marketing. METHODS: We randomly selected schools from the Los Angeles Unified School District and assigned 5 to the intervention group and 5 to a wait-list control group. Of the 4022 seventh-graders across schools, a total of 1368 students had their height and weight assessed at baseline and 2 years' postintervention. RESULTS: A multivariable linear regression was used to predict BMI percentile at ninth grade by using BMI percentile at seventh grade, school indicators, and sociodemographic characteristics (child gender, age, Latino race/ethnicity, US-born status, and National School Lunch Program eligibility [as a proxy for low-income status]). Although the Students for Nutrition and Exercise intervention did not exhibit significant effects on BMI percentile overall, intervention students who were classified as obese at baseline (in seventh grade) showed significant reductions in BMI percentile in ninth grade (b = -2.33 percentiles; SE, 0.83; P = .005) compared with control students. This outcome translated into â¼9 pounds (â¼4.1 kg) lower expected body weight after 2 years for an obese student in the intervention school at the mean height and age of the sample at baseline. CONCLUSIONS: Multilevel school-based interventions can have long-term effects on BMI among students who are obese. Future research should examine the mechanisms by which school-based obesity interventions can affect BMI over time.

PURPOSE: To conduct a randomized controlled trial of Students for Nutrition and eXercise, a 5-week middle school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. METHODS: We randomly selected schools (five intervention, five waitlist control) from the Los Angeles Unified School District. School records were obtained for number of fruits and vegetables served, students served lunch, and snacks sold per attending student, representing an average of 1,515 students (SD = 323) per intervention school and 1,524 students (SD = 266) per control school. A total of 2,997 seventh-graders (75% of seventh-graders across schools) completed pre- and postintervention surveys assessing psychosocial variables. Consistent with community-based participatory research principles, the school district was an equal partner, and a community advisory board provided critical input. RESULTS: Relative to control schools, intervention schools showed significant increases in the proportion of students served fruit and lunch and a significant decrease in the proportion of students buying snacks at school. Specifically, the intervention was associated with relative increases of 15.3% more fruits served (p = .006), 10.4% more lunches served (p < .001), and 11.9% fewer snacks sold (p < .001) than would have been expected in its absence. Pre-to-post intervention, intervention school students reported more positive attitudes about cafeteria food (p = .02) and tap water (p = .03), greater obesity-prevention knowledge (p = .006), increased intentions to drink water from the tap (p = .04) or a refillable bottle (p = .02), and greater tap water consumption (p = .04) compared with control school students. CONCLUSIONS: Multilevel school-based interventions may promote healthy adolescent dietary behaviors.

OBJECTIVE: To describe middle school student attitudes about school drinking fountains, investigate whether such attitudes are associated with intentions to drink water at school, and determine how intentions relate to overall water intake. METHODS: Students (n = 3211) in 9 California middle schools completed surveys between 2009 and 2011. We used multivariate linear regression, adjusting for school sociodemographic characteristics, to examine how attitudes about fountains (5-point scale; higher scores indicating more positive attitudes) were associated with intentions to drink water at school and how intentions to drink water at school were related to overall water intake. RESULTS: Mean age of students was 12.3 (SD = 0.7) years; 75% were Latino, 89% low income, and 39% foreign born. Fifty-two percent reported lower than recommended overall water intake (<3 glasses/day), and 30% reported that they were unlikely or extremely unlikely to drink water at school. Fifty-nine percent reported that school fountains were unclean, 48% that fountain water does not taste good, 33% that fountains could make them sick, 31% that it was not okay to drink from fountains, and 24% that fountain water is contaminated. In adjusted analyses, attitudes about school drinking fountains were related to intentions to drink water at school (ß = 0.41; P < .001); intentions to drink water at school were also associated with overall water intake (ß = 0.20; P < .001). CONCLUSIONS: Students have negative attitudes about school fountains. To increase overall water intake, it may be important to promote and improve drinking water sources not only at school but also at home and in other community environments.
