Utilization patterns in an asthma intervention

Health Disparities: Interventions for Pulmonary Disease - A Narrative Review

There is expansive literature documenting the presence of health disparities, but there are disproportionately few studies describing interventions to reduce disparity. In this narrative review, we categorize interventions to reduce health disparity in pulmonary disease within the US health care system to support future initiatives to reduce disparity. We identified 211 articles describing interventions to reduce disparity in pulmonary disease related to race, income, or sex. We grouped the studies into the following four categories: biologic, educational, behavioral, and structural. We identified the following five main themes: (1) there were few interventional trials compared with the breadth of studies describing health disparities, and trials involving patients with asthma who were Black, low income, and living in an urban setting were overrepresented; (2) race or socioeconomic status was not an effective marker of individual pharmacologic treatment response; (3) telehealth enabled scaling of care, but more work is needed to understand how to leverage telehealth to improve outcomes in marginalized communities; (4) future interventions must explicitly target societal drivers of disparity, rather than focusing on individual behavior alone; and (5) individual interventions will only be maximally effective when specifically tailored to local needs. Much work has been done to catalog health disparities in pulmonary disease. Notable gaps in the identified literature include few interventional trials, the need for research in diseases outside of asthma, the need for high quality effectiveness trials, and an understanding of how to implement proven interventions balancing fidelity to the original protocol and the need to adapt to local barriers to care.

Improving childhood asthma outcomes in East Harlem: the East Harlem Asthma Center of Excellence's Asthma Counselor Program

OBJECTIVES

To evaluate the effectiveness of the Asthma Counselor Program, a program of the New York City Department of Health and Mental Hygiene, designed to improve asthma outcomes among children.

METHODS

We used a pre-post study design among children who enrolled in the program. We included self-reported outcome measures by comparing the previous 12 months (captured at intake) to the 12 months following program enrollment. To calculate the 12 months after enrollment, we added the number of outcome events reported at each follow-up session, which are conducted approximately three months apart, to compute 12-month (or "year-end") post-enrollment outcomes.

RESULTS

We enrolled 136 children during the study period (2018); 85 children remained in the program for 12 months and 51 became lost-to-follow-up. Among those who remained in the program, at the "year-end" session, there were statistically significant reductions in the mean number of asthma-related unscheduled healthcare appointments or urgent-care visits (73%), uses of prednisone (65%), asthma-related school absences (60%), asthma-related ED visits (57%), and asthma-related hospitalizations (50%).

CONCLUSIONS

Twelve months after children enrolled in the program, they had significantly improved asthma outcomes. Our findings, along with results from similar studies, support multicomponent interventions, especially those led by masters-level social workers.

Community-based interventions for childhood asthma using comprehensive approaches: a systematic review and meta-analysis

Objective

We conducted a systematic review and meta-analysis to determine the effectiveness of comprehensive community-based interventions with ≥ 2 components in improving asthma outcomes in children.

Methods

A systematic search of Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Excerpta Medica Database (EMBASE), Cochrane Library and hand search of reference collections were conducted to identify any research articles published in English between 2000 and 2019. All studies reporting community-based asthma interventions with ≥ 2 components (e.g., asthma self-management education, home environmental assessment or care coordination etc.) for children aged ≤ 18 years were included. Meta-analyses were performed using random-effects model to estimate pooled odds ratio (OR) with 95% confidence intervals (CIs).

Results

Of the 2352 studies identified, 21 studies were included in the final analysis: 19 pre-post interventions, one randomised controlled trial (RCT) and one retrospective study. Comprehensive asthma programs with multicomponent interventions were associated with significant reduction in asthma-related Emergency Department (ED) visits (OR = 0.26; 95% CI 0.20–0.35), hospitalizations (OR = 0.24; 95% CI 0.15–0.38), number of days (mean difference = − 2.58; 95% CI − 3.00 to − 2.17) and nights with asthma symptoms (mean difference = − 2.14; 95% CI − 2.94 to − 1.34), use of short-acting asthma medications/bronchodilators (BD) (OR = 0.28; 95% CI 0.16–0.51), and increase use of asthma action plan (AAP) (OR = 8.87; 95% CI 3.85–20.45).

Conclusion

Community-based asthma care using more comprehensive approaches may improve childhood asthma management and reduce asthma related health care utilization.

Factors associated with poor controller medication use in children with high asthma emergency department use

BACKGROUND

Understanding health and social factors associated with controller medication use in children with high-risk asthma may inform disease management in the home and community.

OBJECTIVE

To examine health and social factors associated with the Asthma Medication Ratio (AMR), a measure of guideline-based care and controller medication use, in children with persistent asthma and frequent emergency department (ED) use.

METHODS

Study questionnaires, serum allergen sensitization, salivary cotinine, and pharmacy record data were collected for 222 children enrolled from August 2013 to February 2016 in a randomized clinical trial that tested the efficacy of an ED- and home-based intervention. Logistic regression was used to examine factors associated with an AMR greater than 0.50, reflecting appropriate controller medication use.

RESULTS

Most children were male (64%), African American (93%), Medicaid insured (93%), and classified as having uncontrolled asthma (44%). Almost half (48%) received non-guideline-based care or low controller medication use based on an AMR less than 0.50. The final regression model predicting an AMR greater than 0.50 indicated that children receiving specialty care (odds ratio [OR], 4.87; 95% confidence interval [CI], 2.06-11.50), caregivers reporting minimal worry about medication adverse effects (OR, 0.50; 95% CI, 0.25-1.00), positive sensitization to ragweed allergen (OR, 3.82; 95% CI, 1.63-8.96), and negative specific IgE for dust mite (OR, 0.33; 95% CI, 0.15-0.76) were significantly associated with achieving an AMR greater than 0.50.

CONCLUSION

Clinical decision making for high-risk children with asthma may be enhanced by identification of sensitization to environmental allergens, ascertaining caregiver's concerns about controller medication adverse effects and increased referral to specialty care.

Using Address Information to Identify Hardships Reported by Families of Children Hospitalized With Asthma

OBJECTIVE

Socioeconomic hardship is common among children hospitalized for asthma but often not practically measurable. Information on where a child resides is universally available. We sought to determine the correlation between neighborhood-level socioeconomic data and family-reported hardships.

METHODS

Caregivers of 774 children hospitalized with asthma answered questions regarding income, financial strain, and primary care access. Addresses were geocoded and linked to zip code-, census tract-, and block group-level (neighborhood) data from the US Census. We then compared neighborhood median household income with family-reported household income; percentage of neighborhood residents living in poverty with family-reported financial strain; and percentage of neighborhood households without an available vehicle with family-reported access to primary care. We constructed heat maps and quantified correlations using Kendall rank correlation coefficient. Receiver operator characteristic curves were used to assess predictive abilities of neighborhood measures.

RESULTS

The cohort was 57% African American and 73% publicly-insured; 63% reported income <$30,000, 32% endorsed ≥4 financial strain measures, and 38% reported less than adequate primary care access. Neighborhood median household income was significantly and moderately correlated with and predictive of reported household income; neighborhood poverty was similarly related to financial strain; neighborhood vehicle availability was weakly correlated with and predictive of primary care access. Correlations and predictions provided by zip code measures were similar to those of census tract and block group.

CONCLUSIONS

Universally available neighborhood information might help efficiently identify children and families with socioeconomic hardships. Systematic screening with area-level socioeconomic measures has the potential to inform resource allocation more efficiently.

A systematic review of self-management interventions for children and youth with physical disabilities

PURPOSE

Evidence shows that effective self-management behaviors have the potential to improve health outcomes, quality of life, self-efficacy and reduce morbidity, emergency visits and costs of care. A better understanding of self-management interventions (i.e. programs that help with managing symptoms, treatment, physical and psychological consequences) is needed to achieve a positive impact on health because most children with a disability now live well into adulthood.

METHOD

A systematic review of self-management interventions for school age youth with physical disabilities was undertaken to assess their effectiveness. Comprehensive electronic searches using international web-based reference libraries were conducted for peer-reviewed and gray literature published between 1980 and January 2012. Eligible studies examined the effectiveness of self-management interventions for children and youth between 6 and 18 years of age with congenital or acquired physical disabilities. Studies needed to include a comparison group (e.g. single group pre/post-test design) and at least one quantifiable health-related outcome.

RESULTS

Of the 2184 studies identified, six met the inclusion criteria; two involved youth with spina bifida and four with juvenile arthritis. The majority of the interventions ran several sessions for at least 3 months by a trained interventionist or clinician, had one-to-one sessions and meetings, homework activities and parental involvement. Although outcomes varied between the studies, all of the interventions reported at least one significant improvement in either overall self-management skills or a specific health behavior.

CONCLUSIONS

While self-management interventions have the potential to improve health behaviors, there were relatively few rigorously designed studies identified. More studies are needed to document the outcomes of self-management interventions, especially their most effective characteristics for children and youth with physical disabilities. Implications for Rehabilitation There is some evidence to suggest that self-management interventions for children and youth with spina bifida and arthritis can improve self-management behaviors and health outcomes. Parents' involvement should be considered in encouraging self-management behaviors at different stages of their child's development. Much work is needed to explore the longer term implications of self-management interventions for youth with physical disabilities as well as the impact on health care utilization.

The Breathmobile program: a good investment for underserved children with asthma

BACKGROUND

The Breathmobile, a specialty-based mobile asthma clinic, provides free care to underserved children. The cost of symptom-free day (SFD) improvement in this population has not been previously reported.

OBJECTIVE

To examine the clinical impact and cost-effectiveness of the Baltimore Breathmobile.

METHODS

Existing computerized data were analyzed for Breathmobile patient visits between 2002 and 2007. All SFDs were calculated, and direct medical cost savings attributable to decreased emergency department visits and hospitalizations (after program utilization vs the previous year) were compared with annual operating costs. Incremental cost-effectiveness ratios were determined by calculating the incremental costs of Breathmobile care per additional SFD gained per child per year.

RESULTS

The analysis included 255 patients enrolled in the program for at least 1 year. Most participants were black (93.3%), and 54.9% were male. At baseline, patients reported a mean (SD) of 199 (118) SFDs in the year before enrollment. After 1 year in the program, patients had a mean (SD) improvement of 44 (9) SFDs. The program resulted in overall cost savings of $79.43 per SFD gained, with greater cost savings for children aged 5 to 11 years (-$116.84 per SFD gained) and those with intermittent asthma (-$126.71 per SFD gained).

CONCLUSIONS

The Baltimore Breathmobile program has demonstrated significant improvement in SFDs, with direct medical cost savings of the program outweighing the operational costs. These data support the need to continue to sustain and expand Breathmobile programs for children at high risk for asthma exacerbations and to conduct a randomized clinical trial to estimate the cost-effectiveness of the Breathmobile.

The Child Asthma Link Line: a coalition-initiated, telephone-based, care coordination intervention for childhood asthma

BACKGROUND

Childhood asthma is a complex chronic disease that poses significant challenges regarding management, and there is evidence of disparities in care. Many medical, psychosocial, and health system factors contribute to recognized poor control of this most prevalent illness among children, with resultant excessive use of emergency departments and hospitalizations for care. Recent national guidelines emphasize the need for community-based initiatives to address these critical issues. To address health system fragmentation and impact asthma outcomes, the Philadelphia Allies Against Asthma coalition developed and implemented the Child Asthma Link Line, a telephone-based care coordination and system integration program, which has been in operation since 2001. This study evaluates the effectiveness of the Child Asthma Link Line integration model to improve asthma management by measuring utilization markers of morbidity.

METHODS

Medicaid Managed Care Organization claims data for 59 children who received the Link Line intervention in 2003 are compared to a matched sample of 236 children who did not receive the Link Line intervention. Children in the two study groups are ages 3 through 12 years and matched on 2003 emergency department visits, age, gender, and race/ethnicity. Primary outcome variables analyzed in this study are emergency department visits, hospitalizations, and office visit claims from the follow-up year (2004).

RESULTS

Link Line intervention children were significantly less likely to have follow-up hospitalizations than matched sample children (p = .02). Children enrolled in the Link Line were also more likely to attend outpatient office visits in the follow-up year (p = .045). In addition, Link Line children with multiple emergency department visits in 2003 were significantly less likely to have an emergency department visit in 2004 (p = .046).

CONCLUSION

This coalition-developed, telephone-based, system-level intervention had a significant impact on childhood asthma morbidity as measured by utilization endpoints of follow-up hospitalizations and emergency department visits. Telephone-based care coordination and service integration may be a viable and economic way to impact childhood asthma and other chronic diseases.

The Inner-City Asthma Intervention: description of a community-based implementation of an evidence-based approach to asthma management

BACKGROUND

In 2000, the Centers for Disease Control and Prevention funded a 4-year project to implement the Inner-City Asthma Intervention (ICAI)-an asthma treatment and management project based on the protocol developed for the National Cooperative Inner-City Asthma Study (NCICAS) funded by the National Institutes of Health, National Institute of Allergy and Infectious Disease.

OBJECTIVE

To describe the ICAI's major components and implementation issues.

METHODS

Information contained in this article is based on project activity and management reports, site client tracking and data collection reports, site visit and other program oversight activity, and general subject matter knowledge. The site client tracking data collection process varied among sites during the intervention. Common definitions and processes were developed and implemented as needed.

RESULTS

Three of the 24 original sites discontinued participation. The remaining sites enrolled 4,174 children into the intervention. Although the project ended earlier than originally scheduled, 1,035 children completed the entire intervention. Of the 3,139 children who did not complete the entire protocol, 1,355 children and their families completed the core activities or the core activities plus one or more follow-up activities.

CONCLUSION

The ICAI project demonstrated that although there were a number of implementation issues to overcome, it is possible to implement effectively a proven National Institutes of Health protocol in the community setting.

Implementation of an asthma intervention in the inner city

BACKGROUND

Despite availability of asthma self-management interventions for children, few have been implemented in community-based settings.

OBJECTIVE

To describe implementation of the Inner-City Asthma Intervention and factors associated with higher rates of program completion by enrollees.

METHODS

Descriptive analyses of data from multiple data sources. Two-tailed Pearson correlation coefficients and analyses of variance were used to calculate associations of descriptive variables with the retention rate (percentage of enrolled children who completed the core intervention and had more than 1 follow-up visit) and with the percentage who had allergy testing done.

RESULTS

A total of 4,174 children were enrolled at 22 sites; 2,153 (52%) completed the core intervention and had more than 1 follow-up visit. A total of 2,014 enrolled children (48%) were tested for allergies. Retention was related to type and location of site, ease of obtaining written plans, language and ethnicity of asthma counselor, and on-site allergy testing. Higher rates of allergy testing were associated with the same factors, as well as flexibility in scheduling and selective enrollment of participants.

CONCLUSIONS

Inner-city children with asthma can be enrolled in the Inner-City Asthma Intervention outside a controlled research setting. However, completion of all intervention components is difficult to achieve. We identify having an asthma counselor who is representative of the community, access to asthma action plans, and on-site allergy testing as factors that facilitate the implementation of this intervention in community-based settings.

From research to reality: from the National Cooperative Inner-City Asthma Study to the inner-city asthma implementation

Several themes emerged from the information provided in this supplement. 1. Implementation of the protocol was feasible, although retention of participants was challenging and customization at each site was essential. 2. Master's degree level social workers were well suited to partnering with health care professionals to address the many issues involved in caring for children with asthma and their families. 3. Collaboration between team members and community partners was critical to successful implementation. 4. Sustainability beyond external funding is attainable if local funding is sought and outcome measures that are considered important to the community are measured and reported.
