Improving asthma research in an inner-city Latino neighborhood with community health workers

Association of neighborhood crime with asthma and asthma morbidity among Mexican American children in Chicago, Illinois

BACKGROUND

There is increasing evidence that neighborhood-level factors, in addition to individual-level factors, may contribute directly or indirectly to childhood asthma by affecting environmental and lifestyle factors. Exposure to neighborhood crime and violence has been associated with poor health outcomes, especially among underserved and minority populations, and its effect on respiratory health is an area of active research.

OBJECTIVE

To examine the association of residential neighborhood crime with asthma and asthma-related outcomes among Mexican American children.

METHODS

This cross-sectional study was conducted with parents of 2,023 Mexican American children. We derived measures of neighborhood (census tract) violent, property, and drug abuse crime and used multilevel generalized estimating equations to test associations of neighborhood crime counts with respiratory conditions.

RESULTS

In multiple regression models, a 1-SD increase in neighborhood property crimes significantly increased the odds of lifetime asthma, lifetime wheezing, lifetime emergency department (ED) visits attributable to asthma or wheezing, and lifetime hospitalization attributable to asthma or wheezing by 25%, 18%, 44%, and 62%, respectively. A 1-SD elevation in neighborhood violent crime was positively and significantly associated with 21% and 57% higher odds of lifetime wheezing and ED visits, respectively. We also observed 13% and 44% significantly increased odds of lifetime wheezing and ED visits, respectively, for a 1-SD increase in drug abuse crime. These findings were not explained or modified by individual- and neighborhood-level covariates.

CONCLUSION

Higher neighborhood crime was associated with greater odds of asthma and asthma morbidity in Mexican American children.

Short or Long End of the Lever? Associations between Provider Communication of the "Asthma-Action Plan" and Outpatient Revisits for Pediatric Asthma

BACKGROUND

At the Children's Hospital of Georgia (CHOG), we found that outpatient revisits for pediatric asthma were significantly above national norms. According to the NIH, costly hospital revisits for asthma can be prevented through guidelines-based self-management of asthma, central to which, is the use of a written Asthma-Action Plan (AAP).

PURPOSE

The asthma services literature has emphasized the role of the healthcare provider in promoting asthma self-management using the AAP, to prevent hospital revisits. On the other hand, the asthma policy literature has emphasized the need for community-based interventions to promote asthma self-management. A gap remains in understanding the extent of leverage that healthcare providers may have in preventing hospital revisits for asthma, through effective communication of AAP in the outpatient setting. Our study sought to address this gap.

METHODS

We conducted a 6-month intervention to implement "patient-and-family-centered communication of the AAP" in CHOG outpatient clinics, based on the "change-management" theoretical framework. Provider communication of AAP was assessed through a survey of "Parent Understanding of the Child's AAP." A quasi-experimental approach was used to measure outpatient revisits for pediatric asthma, pre- and post-intervention.

RESULTS

Survey results showed that provider communication of the AAP was unanimously perceived highly positively by parents of pediatric asthma patients, across various metrics of patient-centered care. However, there were no statistically significant differences in outpatient "revisit behavior" for pediatric asthma between pre- and post-intervention periods after controlling for several demographic variables. Additionally, revisits remained significantly above national norms.

CONCLUSIONS

Results suggest limited potential of "effective provider communication of AAP," in reducing outpatient revisits for pediatric asthma; and indicate need for broader community-based interventions to address patient life variables impacting self-management and hospital revisits for pediatric asthma. Findings suggest need for a revised "socio-ecological" theoretical framework, and also provide insight into various policy, research, and practice implications for asthma management and control.

Supporting Latino communities' natural helpers: a case study of promotoras in a research capacity building course

Promotores have unique access to underserved and hard-to-reach Latino communities facing health disparities. Although promotores are involved in community change, they rarely receive training that gives them the skills to be partners in research. We present a case study of promotoras who participated in a research capacity building course focused on assessing community health needs. Data comes from course application surveys, follow-up notes, and narratives from qualitative phone interviews of eight promotoras. Content analysis drawing from grounded theory was conducted to identify and describe emerging themes. Four themes emerged as promotoras discussed their experience learning basic research skills and teaching others: (1) challenges, (2) support, (3) building capacity, and (4) using research. Promotores play an important role in the health of Latino communities and are increasingly asked to participate in research processes; however they have few opportunities for training and professional development in this area. Capacity building opportunities for promotores need to be tailored to their needs and provide them with support. Fostering collaboration between promotores and partnering with local community-based organizations can help facilitate needed research skill-building among promotores.

Improving asthma management among African-American children via a community health worker model: findings from a Chicago-based pilot intervention

OBJECTIVES

Asthma affects 25-30% of children living in certain disadvantaged Chicago neighborhoods, a rate twice the national prevalence (13%). Children living in poor, minority communities tend to rely heavily on the emergency department (ED) for asthma care and are unlikely to be properly medicated or educated on asthma self-management. A pilot project implemented and evaluated a community health worker (CHW) model for its effectiveness in reducing asthma morbidity and improving the quality of life among African-American children living in disadvantaged Chicago neighborhoods.

METHODS

Trained CHWs from targeted communities provided individualized asthma education during three to four home visits over 6 months. The CHWs also served as liaisons between families and the medical system. Seventy children were enrolled into the pilot phase between 15 November 2004 and 15 July 2005, of which 96% were insured by Medicaid and 54% lived with a smoker. Prior to starting, the study was approved by an institutional review board. Data on 50 children (71.4%) who completed the entire 12-month evaluation phase were analyzed using a before and after study design.

RESULTS

Findings indicate improved asthma control. Specifically, symptom frequency was reduced by 35% and urgent health resource utilization by 75% between the pre- and post-intervention periods. Parental quality of life also improved by a level that was both clinically and statistically significant. Other important outcomes included improved asthma-related knowledge, decreased exposure to asthma triggers, and improved medical management. The intervention was also shown to be cost-effective, resulting in an estimated $5.58 saved per dollar spent on the intervention.

CONCLUSIONS

Findings suggest that individualized asthma education provided by a trained, culturally competent CHW is effective in improving asthma management among poorly controlled, inner-city children. Further studies are needed to affirm the findings and assess the model's generalizability.

Development of project wings home visits, a mental health intervention for Latino families using community-based participatory research

As the Latino population in the United States experiences rapid growth, the well-being of Latino adolescents is a growing concern because of their high rates of mental health problems. Latino adolescents have higher rates of mental health problems than their peers, including depressive symptoms, suicide attempts, and violence. Sophisticated, realistic health promotion efforts are needed to reduce these risk behaviors and enhance protective factors. Parents and schools can be key protective factors, or assets, in adolescents' lives. This article details the steps undertaken to develop Project Wings Home Visits, a collaborative school-based, community-linked mental health promotion intervention for Latino adolescents and their families. Core to the intervention is the use of a community health worker model to provide home-based outreach and education to parents of Latino adolescents. The intervention was developed using a community-based participatory research approach that involved the cooperation of a community health care system, a public high school, and a university. Our process demonstrates the benefits, strengths, and challenges of using community-based participatory research in creating and implementing health promotion interventions.

One gets so afraid: Latino families and asthma management--an exploratory study

INTRODUCTION

This study explored Latino family experiences, issues, and needs in caring for a child with asthma as expressed by Latino parents of children with asthma.

METHODS

Eight families represented by 7 women and 2 men, primarily of Mexican descent, participated in the study. All families had at least one child enrolled in preschools in the East Los Angeles area. The study had an exploratory design and used ethnographic group and individual interview techniques to discover the parents' experiences in managing their child's asthma and the meaning asthma has for their families. All interviews were conducted in Spanish.

RESULTS

Several common themes emerged from the data: (a) fear, "I got scared"; (b) the acute care experience, "I was not told what to do, nothing"; (c) knowledge, "I did not know anything about asthma"; and (d) parent alternative strategies or strengths, "We want to do what is best. ... we need to be prepared."

DISCUSSION

Strength emerged from fear. The parents were resourceful and began developing alternative strategies to assist them in their care for their child with asthma. The findings emphasize the need for more opportunities for culturally sensitive asthma education and community health care resources such as mobile asthma treatment centers and promotora programs.

Reducing home triggers for asthma: the Latino community health worker approach

This study assessed the ability of a community health worker asthma intervention to change home asthma triggers. A total of 56 children and 47 adults with asthma were enrolled. Home trigger scores for the children averaged 2.8 at the initial home visit and then 2.3, 2.1, and 2.0 at 3, 6, and 12 months. Home trigger scores for the adults showed a similar trend. Every home visit was associated with a 0.32 reduction in home trigger score (p < 0.01) for children and a 0.41 reduction (p < 0.01) for adults. This intervention shows promise as a way to reduce asthma triggers in urban low-income Latino communities.
