HABIT, a Randomized Feasibility Trial to Increase Hydroxyurea Adherence, Suggests Improved Health-Related Quality of Life in Youths with Sickle Cell Disease.

OBJECTIVES: To examine the effect of a community health worker (CHW) intervention, augmented by tailored text messages, on adherence to hydroxyurea therapy in youths with sickle cell disease, as well as on generic and disease-specific health-related quality of life (HrQL) and youth-parent self-management responsibility concordance. STUDY DESIGN: We conducted a 2-site randomized controlled feasibility study (Hydroxyurea Adherence for Personal Best in Sickle Cell Treatment [HABIT]) with 2:1 intervention allocation. Youths and parents participated as dyads. Intervention dyads received CHW visits and text message reminders. Data were analyzed using descriptive statistics, the Wilcoxon signed-rank test, and growth models adjusting for group assignment, time, and multiple comparisons. Changes in outcomes from 0 to 6 months were compared with their respective minimal clinically important differences. RESULTS: A total of 28 dyads (mean age of youths, 14.3 ± 2.6 years; 50% Hispanic) participated (18 in the intervention group, 10 in the control group), with 10.7% attrition. Accounting for group assignment, time, and multiple comparisons, at 6 months intervention youths reported improved generic HrQL total score (9.8 points; 95% CI, 0.4-19.2) and Emotions subscale score (15.0 points; 95% CI, 1.6-28.4); improved disease-specific subscale scores for Worry I (30.0 points; 95% CI, 8.5-51.5), Emotions (37.0 points, 95% CI, 9.4-64.5), and Communication I (17.8 points; 95% CI, 0.5-35.1); and 3-month dyad self-management responsibility concordance (3.5 points; 95% CI, -0.2 to 7.1). There were no differences in parent proxy-reported HrQL measures at 6 months. CONCLUSIONS: These findings add to research examining effects of behavioral interventions on HrQL outcomes in youths with sickle cell disease. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02029742.

Factors related to weight loss attempt among Dominican immigrants.

To assess weight loss attempt among a Latino immigrant population from the Dominican Republic we analyzed data on 585 overweight and obese Dominicans from a cross-sectional survey using Chi-square statistics, Student's t-tests, and logistic regression models. We found 58% of the overweight and obese tried to lose weight. Female gender (OR 2.28, CI 1.53-3.39), overweight perception (OR 2.37, CI 1.57-3.60) and weight loss advice from health professionals (OR 1.90, CI 1.24-2.91) were strongly associated with weight loss attempt. Individuals with diabetes were more likely to receive advice to lose weight (OR 2.58, CI 1.18-5.63; yet, they were more satisfied with their weight (40.5 vs. 27.8%, p < 0.021), and no difference in their weight loss attempt (p = 0.849) was detected compared to individuals without diabetes. We conclude a significant proportion of overweight and obese Dominican immigrants do not attempt to lose weight. Overweight perception and, except among individuals with diabetes, weight loss advice were strong inducements to weight loss attempt.

Outcomes from a cross-site evaluation of a comprehensive pediatric asthma initiative incorporating translation of evidence-based interventions.

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.

Community-based care coordination: practical applications for childhood asthma.

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.

Balancing "fidelity" and community context in the adaptation of asthma evidence-based interventions in the "real world".

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.

The prevalence of cardiovascular risk conditions and awareness among a Latino subgroup: Dominicans in northern Manhattan.

OBJECTIVE: To determine the prevalence of cardiovascular risks and identify early opportunities for prevention among Dominican adults residing in New York City. STUDY DESIGN AND METHODS: A cross-sectional survey was conducted among a convenience sample of Dominicans recruited through extensive outreach in the community. All participants were interviewed and received an anthropometeric and laboratory examination pertaining to cardiovascular risk. RESULTS: 17% had diabetes; another 20% had impaired fasting glucose or impaired glucose tolerance; 56% had high cholesterol levels; 41% had hypertension upon examination; 75% were either overweight or obese. The Dominican diagnosed diabetes prevalence significantly exceeded comparable rates among US Latinos dominated by Mexican Americans, while their hypertension prevalence exceeded both US Latino and African American rates. Dominicans were more obese than either US Latino or African Americans, but they had the lowest proportion with high cholesterol. While >80% had a clinical encounter in the last 12 months, 29% were unaware that they had diabetes; 39% did not know they had hypertension, and 50% were unaware of their high cholesterol levels. CONCLUSIONS: The prevalence of cardiovascular risk conditions among Dominicans in New York is higher than the rate for US Latinos for selected but not all conditions. In addition, many missed opportunities exist for prevention and early diagnosis. Future research and cardiovascular risk prevention programs need to pay attention to differences of cardiovascular risk among Latino subgroups.

Elevated asthma and indoor environmental exposures among Puerto Rican children of East Harlem.

OBJECTIVE: East Harlem in New York City, a community with a large Puerto Rican population, has among the highest rates of asthma hospitalizations and mortality in the United States, but it is not known if the high rates are related to the ethnic composition, environmental or community factors, or if the higher rates reflect differentials in access to appropriate asthma care. A survey was conducted to: (a) estimate the prevalence of current asthma by ethnicity among school-age children, (b) assess indoor environmental risk factors for childhood asthma, and (c) assess health care utilization and school absences associated with childhood asthma. DESIGN: A cross-sectional survey of parents of elementary school children, using a self-administered questionnaire with a 12-month recall on asthma symptoms based on the International Study of Asthma and Allergies in Childhood. SETTING: Two public elementary schools in East Harlem (n = 1615 students 5-12 years of age). RESULTS: Among the 1319 respondents (response rate 82%), the prevalence for current asthma (doctor or nurse diagnosis at any time plus wheezing in the past 12 months) was 23%. Puerto Rican children had a prevalence of 35%. Puerto Rican children reported both higher symptomatic frequencies and higher rates of physician diagnosis. Living in a home where cockroaches, rats, or mice had been seen in the past month and with a dust-enhancing heating system also was associated with having asthma, regardless of ethnicity. Compared with other children with asthma, Puerto Rican children with asthma were more likely to live in homes where rats or mice had been seen in the past month. Regardless of ethnicity, children with more frequent, more severe asthma symptoms and incomplete asthma action plans were more likely to have visited the emergency department in the past year. Puerto Rican children were more likely to have missed school because of their asthma in the past year. CONCLUSION: The prevalence of current asthma was significantly higher among Puerto Ricans, who had higher symptomatic frequency and greater diagnosis rates. Although all children with asthma in the East Harlem study appear to be sensitive to selected indoor environmental risk factors, only Puerto Rican children with asthma appear to be sensitive to the presence of rodents in their buildings. However, their higher school absence rate suggests problems with routine asthma management that could be addressed by improved medical management, programs to help parents manage their children's asthma, or school staff assistance with medications.
