The Effects of Caregiver Social Support and Depressive Symptoms on Child Medication Adherence and Asthma Control.

The purpose of this study was to examine relationships among caregiver social support, caregiver depressive symptoms, medication adherence, and asthma control in a sample of low-income, urban, Black children aged 3-12 years with uncontrolled asthma and their caregivers. Using longitudinal data from a randomized controlled trial (RCT) assessing the efficacy of an environmental control educational intervention, we used generalized estimating equations and ordered logistic regression models to evaluate the relationship between caregiver social support (Medical Outcomes Study Social Support Survey), depressive symptoms (Center for Epidemiologic Studies Depression scale), and two child asthma outcomes: (a) medication adherence (Asthma Medication Ratio) and (b) asthma control. At baseline, 45.7% of the 208 children had very poorly controlled asthma. Nearly a third of caregivers (97% female) had clinically significant depressive symptoms at each data collection point. Social support was not associated with either asthma outcome nor did it moderate the relationship between depressive symptoms and child asthma outcomes. Higher caregiver depressive symptoms predicted decreased medication adherence (b=-0.003, SE 0.002). Moderate asthma at baseline (OR: 0.305, SE: 0.251), severe asthma at baseline (OR: 0.142, SE: 0.299), household income < $20,000 per year (OR: 0.505, SE: 0.333), and fall season (OR: 0.643, SE: 0.215) were associated with poorer asthma control. Attending to the social context of low-income, urban, Black children with asthma is critical to reduce asthma morbidity. Maternal depressive symptoms are modifiable and should be targeted in interventions to improve child asthma outcomes in this vulnerable population. The RCT was registered with ClinicalTrials.gov (NCT01981564) in October 2013.

Caregiver Depressive Symptoms and Primary Medication Nonadherence in Children With Asthma.

INTRODUCTION: The purpose of this study was to identify risk factors for primary medication nonadherence among low-income minority children with persistent asthma. METHOD: Data were from an environmental control and educational intervention for children with uncontrolled asthma who were treated in the emergency department for an asthma exacerbation. Presence or absence of pharmacy records for child asthma medications was the outcome of interest. A range of sociodemographic, health, and psychosocial measures were included in the binary logistic regression. RESULTS: Of the 222 youths (mean age = 6.3 years; 93.7% Black), 25 (11.3%) lacked pharmacy records of asthma medications. For every 1-point increase in caregiver depressive symptoms, the odds of the child having a pharmacy record declined by 5% (odds ratio = 0.95; p = .012). DISCUSSION: Providers should systematically assess and monitor caregiver depressive symptoms as a potential contributing factor for primary medication nonadherence in low-income minority children with persistent, uncontrolled asthma.

Fostering Effective Asthma Self-Management Transfer in High-Risk Children: Gaps and Opportunities for Family Engagement.

INTRODUCTION: The process of self-management knowledge, behavior, and skill development in children with asthma from families with low income is understudied. METHOD: Fifteen mothers of children with uncontrolled asthma participated in semistructured interviews exploring the transfer of asthma self-management responsibilities from parent to child. Team members performed thematic analysis of written transcripts. RESULTS: All participants were all the biological mothers and were impoverished, with most (73%) reporting an annual family income of less than $30,000. Their children ranged from 5 to 15 years old, were African American (100%), and had uncontrolled asthma based on national guidelines. Themes showed that child asthma self-management is difficult to achieve, that the transfer of asthma responsibility from mother to child is variable, and that mothers overestimate their child's developmental capacities for independent asthma self-management and have poor understanding of what well-controlled asthma means. DISCUSSION: Ongoing assessment and tailored guidance from health care providers are critical to support the pivotal role of mothers in their child's self-management development process.

Characteristics of inner-city children with life-threatening asthma.

BACKGROUND: Intensive care unit (ICU) admission is a risk factor for fatal asthma. Little is known about risk factors for pediatric ICU admissions for asthma. OBJECTIVE: To examine characteristics of underserved minority children with prior ICU admissions for asthma. METHODS: Baseline survey data, salivary cotinine levels, and allergen specific IgE serologic test results were obtained from children with uncontrolled asthma enrolled in a randomized clinical trial of a behavioral education environmental control intervention. Characteristics of children with and without prior ICU admission were compared using χ2 and t tests. Logistic regression assessed significance of higher odds of prior ICU admission comparing factor-level categories. RESULTS: Patients included 222 primarily African American (93.7%), male (56%), Medicaid-insured (92.8%) children with a mean (SD) age of 6.4 (2.7) years with uncontrolled asthma. Most (57.9%) had detectable cotinine levels, 82.6% were sensitized to more than 1 environmental allergen, and 27.9% had prior ICU admissions. Prior ICU patients were more likely to be very poor (<$10,000 per year) and sensitized to more than 1 allergen tested (most importantly mouse) (P < .05). Allergen sensitization in the groups did not differ for cockroach, cat, dog, Alternaria, Aspergillus, dust mite, grass, or tree. Although more ICU patients received combination controller therapy, they also overused albuterol. Only 27.4% of ICU patients received specialty care in the previous 2 years, which was not significantly different from non-ICU patients. CONCLUSION: Children with high mortality risk, including history of ICU admission, were twice as likely to live in extreme poverty, have atopy (particularly mouse allergen), use combination controller therapy, and overuse albuterol.

Very Poorly Controlled Asthma in Urban Minority Children: Lessons Learned.

BACKGROUND: Very poorly controlled (VPC) asthma in children is associated with ongoing acute exacerbations but factors associated with VPC are understudied. OBJECTIVE: To examine the risk factors associated with VPC asthma in urban minority children. METHODS: This descriptive study examined asthma control levels (well-controlled [WC], not well-controlled [NWC], and VPC) at baseline and 6 months in children participating in an ongoing randomized controlled trial of an emergency department/home environmental control intervention. Data collection occurred during the index emergency department visit and included allergen-specific IgE and salivary cotinine testing and caregiver interview of sociodemographic and child health characteristics. Follow-up data were collected at 6 months. Unadjusted analyses examined the association of sociodemographic and health characteristics by level of asthma control. Multivariate analysis tested significant factors associated with VPC asthma at 6 months. RESULTS: At baseline most children were categorized with VPC asthma (WC, 0%; NWC, 47%; VPC, 53%) and rates of VPC minimally improved at 6 months (WC, 13%; NWC, 41%; VPC, 46%). Risk for VPC asthma was twice as likely in children with allergic rhinitis (odds ratio [OR], 2.42), having 2 or more primary care provider asthma visits within the past 3 months (OR, 2.77), or caregiver worry about medication side effects (OR, 2.13) and 3 to 4 times more likely when asthma control was assessed during the fall or spring season (OR: fall, 3.32; spring, 4.14). CONCLUSIONS: Improving asthma control in low-income, high-risk children with VPC asthma requires treatment of comorbidities, attention to caregiver medication beliefs, and adept use of stepwise therapy.

Characterization of Stress in Low-Income, Inner-City Mothers of Children with Poorly Controlled Asthma.

The goal of this longitudinal analysis was to characterize factors associated with the experience of life stress in low-income, inner-city mothers of minority children with high-risk asthma.Participants (n = 276) reported on family demographics, child asthma control and healthcare utilization, social support, contemporary life difficulties (housing, finances, violence exposure) measured by the validated Crisis in Family Systems scale, and daily stress. Latent growth curve modeling examined predictors of life stress across 12 months as a function of home and community difficulties, asthma-specific factors, and social support. Mothers were primarily single (73%), unemployed (55%), and living in extreme poverty with most (73%) reporting an annual family income <$20,000 (73%). The children were young (mean age = 5.59, SD = 2.17), African-American (96%), and had poorly controlled asthma (94%) at study enrollment. Higher daily stress was associated with financial difficulties, safety concerns in the home and community, and housing problems. Access to social support was consistently related to reduced stress. The only asthma-specific factor associated with life stress was healthcare utilization, with more emergency services for asthma related to higher daily stress. Findings underscore the clinical significance of assessing diverse home and community stressors and social support in low-income, inner-city caregivers of children with poorly controlled asthma.

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.

Caregiver perception of asthma management of children in the context of poverty.

OBJECTIVE: Low-income caregivers of young children with high-risk asthma experience social stressors and illness-related demands that may impede effective home asthma management. Knowledge of the caregiving experience in the context of poverty is limited. METHODS: Convenience sampling methods were used to recruit low-income caregivers of children aged 7-12 years, who are frequently in the Emergency Room (ED) for uncontrolled asthma. Thirteen caregivers participated in focus groups that were designed to elicit reflections on asthma home and community management from the caregiver perspective. A grounded theory approach was used in the open coding of transcript data from three focus groups, as well as to revise and reorganize emerging themes and sub-themes. RESULTS: Participants (Mean age = 33.9 years) were predominantly the biological mother (92.3%), single (84.6%), and impoverished (69.2% reported annual household income ≤ $30,000). Their children (Mean age = 7.8 years) were African-American (100%), enrolled in Medicaid (92.3%), averaged 1.38 (SD = 0.7) ED visits over the prior 3 months, resided in homes with at least one smoker (61.5%), and nearly all (84.6%) experienced activity limitations due to asthma. Five themes emerged in the analysis: intensive caregiving role, complex and shared asthma management responsibility, parental beliefs and structural barriers to guideline-based care, lack of control over environmental triggers, and parent advocacy to improve child asthma care and outcomes. CONCLUSIONS: Caregivers managing a child with high-risk asthma in the context of poverty indicate the need for ongoing asthma education, increased sensitivity to the complexity of home asthma management, and family-centered interventions that enhance communication and collaboration between caregivers and providers.

Asthma Home Management in the Inner-City: What can the Children Teach us?

OBJECTIVE: Knowledge of asthma home management from the perspective of poor, minority children with asthma is limited. METHOD: Convenience sampling methods were used to recruit families of low-income children who are frequently in the emergency department for uncontrolled asthma. Thirteen youths participated in focus groups designed to elicit reflections on asthma home management. Data were analyzed using grounded theory coding techniques. RESULTS: Participants (Mean age = 9.2 years) were African American (100%), enrolled in Medicaid (92.3%), averaged 1.4 (standard deviation = 0.7) emergency department visits over the prior 3 months, and resided in homes with at least 1 smoker (61.5%). Two themes reflecting multifaceted challenges to the development proper of self-management emerged in the analysis. DISCUSSION: Findings reinforce the need to provide a multipronged approach to improve asthma control in this high-risk population including ongoing child and family education and self-management support, environmental control and housing resources, linkages to smoking cessation programs, and psychosocial support.

Parents of Children With Food Allergy: Gender Differences in Perceived Impact and Perceived Food Allergy Severity.

Objective: To compare fathers' and mothers' perceptions of the impact and severity of their child's food allergy and their levels of involvement in allergy-related care. Methods: One hundred parents of children with food allergy (50 mother-father pairs) rated the severity of their child's food allergies and completed the Food Allergy Impact Scale. A subset of 52 parents reported how often they engaged in food allergy-related care. Results: Mothers reported more impact than fathers for meal preparation, family social activities, and stress and free time, and significantly greater involvement in allergy-related care. Fathers who reported more frequent medical appointment attendance perceived meal preparation as being significantly more impacted by food allergy than fathers who were less involved. Conclusions: Fathers who are less involved may be buffered from experiencing the impact of their child's health condition. Differences in involvement rather than other gender differences may explain discrepancies in mothers' and fathers' illness perceptions.

Parental decision making associated with pediatric emergency department use for asthma.

BACKGROUND: Disadvantaged minority children are disproportionately affected by asthma. This group is also known to frequently use the emergency department (ED) for asthma care. Understanding decisions for use of the ED is important to prevent high cost. OBJECTIVE: To examine caregiver factors associated with the decision to use the ED for asthma care in inner-city children with asthma. METHODS: One hundred fifty participants in a randomized clinical trial testing the effectiveness of a home-based asthma intervention were enrolled, and questionnaires were administered to caregivers during the child's ED asthma visit. Sociodemographics, health characteristic data, and caregiver interview data were examined to ascertain factors that affected caregiver decision making to use the ED for asthma care. A cluster analysis was performed to correlate caregiver reasons for the decision to use the ED for asthma care. RESULTS: Three clusters emerged for decision making: urgency, preference for the use of the ED, and access to care issues. The perception of urgency was the most common reason reported by caregivers (91%) followed by reporting a preference for the ED for care (37%) and reporting access to care issues (31%). Access to care was primarily attributable to the inability to get a same-day appointment with their primary care practitioner (24%). CONCLUSION: The caregiver factors involved in the decision to use the ED can provide a basis for further intervention and investigation. Such factors include caregiver asthma home management, improvement in relationships with primary care practitioners, and access to care-related issues.

Factors associated with high short-acting ß2-agonist use in urban children with asthma.

BACKGROUND: One goal of guideline-based asthma therapy is minimal use of short-acting ß2 agonist (SABA) medications. Inner-city children with asthma are known to have high SABA use. OBJECTIVE: To examine factors associated with high SABA use in inner-city children with asthma. METHODS: One hundred inner-city children with persistent asthma were enrolled into a randomized controlled trial of an emergency department (ED) and home intervention. All children underwent serologic allergen specific IgE and salivary cotinine testing at the ED enrollment visit. Pharmacy records for the past 12 months were obtained. Number of SABA fills during the past 12 months was categorized into low- to moderate- vs high-use groups. SABA groups were compared by the number of symptom days and nights, allergen sensitization, and exposures. Regression models were used to predict high SABA use. RESULTS: Mean number of SABA fills over 12 months was 3.12. Unadjusted bivariate analysis showed that high SABA users were more than 5 times more likely to have an asthma hospitalization, almost 3 times more likely to have an asthma intensive care unit admission, and more than 3 times more likely to have prior specialty asthma care or positive cockroach sensitization than low to moderate SABA users. In the final regression model, for every additional inhaled corticosteroid fill, a child was 1.4 times more likely and a child with positive cockroach sensitization was almost 7 times more likely to have high SABA use when controlling for prior intensive care unit admission, receipt of specialty care, child age, and income. CONCLUSION: Providers should closely monitor SABA and controller medication use, allergen sensitization, and exposures in children with persistent asthma. TRIAL REGISTRATION: ClinicalTrials.gov, identifier NCT01981564.

Parenting and independent problem-solving in preschool children with food allergy.

OBJECTIVE: To examine autonomy-promoting parenting and independent problem-solving in children with food allergy. METHODS: 66 children with food allergy, aged 3-6 years, and 67 age-matched healthy peers and their mothers were videotaped while completing easy and difficult puzzles. Coders recorded time to puzzle completion, children's direct and indirect requests for help, and maternal help-giving behaviors. RESULTS: Compared with healthy peers, younger (3- to 4-year-old) children with food allergy made more indirect requests for help during the easy puzzle, and their mothers were more likely to provide unnecessary help (i.e., explain where to place a puzzle piece). Differences were not found for older children. CONCLUSIONS: The results suggest that highly involved parenting practices that are medically necessary to manage food allergy may spill over into settings where high levels of involvement are not needed, and that young children with food allergy may be at increased risk for difficulties in autonomy development.

Mobile health care operations and return on investment in predominantly underserved children with asthma: the breathmobile program.

Underserved populations have limited access to care. Improved access to effective asthma care potentially improves quality of life and reduces costs associated with emergency department (ED) visits. The purpose of this study is to examine return on investment (ROI) for the Breathmobile Program in terms of improved patient quality-adjusted life years saved and reduced costs attributed to preventable ED visits for 2010, with extrapolation to previous years of operation. It also examines cost-benefit related to reduced morbidity (ED visits, hospitalizations, and school absenteeism) for new patients to the Breathmobile Program during 2008-2009 who engaged in care (≥3 visits). This is a retrospective analysis of data for 15,986 pediatric patients, covering 88,865 visits, participating in 4 Southern California Breathmobile Programs (November 16, 1995-December 31, 2010). The ROI calculation expressed the cost-benefit ratio as the net benefits (ED costs avoided+relative value of quality-adjusted life years saved) over the per annum program costs (∼$500,000 per mobile). The ROI across the 4 California programs in 2010 was $6.73 per dollar invested. Annual estimated emergency costs avoided in the 4 regions were $2,541,639. The relative value of quality-adjusted life years saved was $24,381,000. For patients new to the Breathmobile Program during 2008-2009 who engaged in care (≥3 visits), total annual morbidity costs avoided per patient were $1395. This study suggests that mobile health care is a cost-effective strategy to deliver medical care to underserved populations, consistent with the Triple Aims of Therapy.

Stress and quality of life in caregivers of inner-city minority children with poorly controlled asthma.

INTRODUCTION: Caregiver quality of life (QOL) is known to influence asthma management behaviors. Risk factors for low caregiver QOL in families of inner-city children with asthma remain unclear. This study evaluated the interrelationships of asthma control, stress, and caregiver QOL. METHOD: Data were analyzed from a home-based behavioral intervention for children with persistent asthma after treatment for asthma in the emergency department. Caregivers reported on baseline demographics, asthma control, asthma management stress, life stress, and QOL. Hierarchical regression analysis examined the contributions of sociodemographic factors, asthma control, asthma management stress, and life stress in explaining caregiver QOL. RESULTS: Children (N = 300) were primarily African American (96%) and young (mean age, 5.5 years). Caregivers were predominantly the biological mother (92%), single (70%), and unemployed (54%). Poor QOL was associated with higher caregiver education and number of children in the home, low asthma control, and increased asthma management stress and life stress. The model accounted for 28% of variance in caregiver QOL. DISCUSSION: Findings underscore the need for multifaceted interventions to provide tools to caregivers of children with asthma to help them cope with asthma management demands and contemporary life stressors.

Factors associated with completion of a behavioral intervention for caregivers of urban children with asthma.

BACKGROUND: Rates of preventive follow-up asthma care after an acute emergency department (ED) visit are low among inner-city children. We implemented a novel behavioral asthma intervention, Pediatric Asthma Alert (PAAL) intervention, to improve outpatient follow-up and preventive care for urban children with a recent ED visit for asthma. OBJECTIVE: The objective of this article is to describe the PAAL intervention and examine factors associated with intervention completers and noncompleters. METHODS: Children with persistent asthma and recurrent ED visits (N = 300) were enrolled in a randomized controlled trial of the PAAL intervention that included two home visits and a facilitated follow-up visit with the child's primary care provider (PCP). Children were categorized as intervention completers, that is, completed home and PCP visits compared with noncompleters, who completed at least one home visit but did not complete the PCP visit. Using chi-square test of independence, analysis of variance, and multiple logistic regression, the intervention completion status was examined by several sociodemographic, health, and caregiver psychological variables. RESULTS: Children were African-American (95%), Medicaid insured (91%), and young (aged 3-5 years, 56%). Overall, 71% of children randomized to the intervention successfully completed all home and PCP visits (completers). Factors significantly associated with completing the intervention included younger age (age 3-5 years: completers, 65.4%; noncompleters, 34.1%; p < .001) and having an asthma action plan in the home at baseline (completers: 40%; noncompleters: 21%; p = .02). In a logistic regression model, younger child age, having an asthma action plan, and lower caregiver daily asthma stress were significantly associated with successful completion of the intervention. CONCLUSIONS: The majority of caregivers of high-risk children with asthma were successfully engaged in this home and PCP-based intervention. Caregivers of older children with asthma and those with high stress may need additional support for program completion. Further, the lack of an asthma action plan may be a marker of preexisting barriers to preventive care.

Factors associated with second-hand smoke exposure in young inner-city children with asthma.

OBJECTIVES: To examine the association of social and environmental factors with levels of second-hand smoke (SHS) exposure, as measured by salivary cotinine, in young inner-city children with asthma. METHODS: We used data drawn from a home-based behavioral intervention for young high-risk children with persistent asthma post-emergency department (ED) treatment (N = 198). SHS exposure was measured by salivary cotinine and caregiver reports. Caregiver demographic and psychological functioning, household smoking behavior, and asthma morbidity were compared with child cotinine concentrations. Chi-square and ANOVA tests and multivariate regression models were used to determine the association of cotinine concentrations with household smoking behavior and asthma morbidity. RESULTS: Over half (53%) of the children had cotinine levels compatible with SHS exposure and mean cotinine concentrations were high at 2.42 ng/ml (SD 3.2). The caregiver was the predominant smoker in the home (57%) and 63% reported a total home smoking ban. Preschool aged children and those with caregivers reporting depressive symptoms and high stress had higher cotinine concentrations than their counterparts. Among children living in a home with a total home smoking ban, younger children had significantly higher mean cotinine concentrations than older children (cotinine: 3-5 year olds, 2.24 ng/ml (SD 3.5); 6-10 year olds, 0.63 ng/ml (SD 1.0); p < .05). In multivariate models, the factors most strongly associated with high child cotinine concentrations were increased number of household smokers (ß = 0.24) and younger child age (3-5 years) (ß = 0.23; p < .001, R(2) = 0.35). CONCLUSION: Over half of the young inner-city children with asthma were exposed to SHS, and caregivers are the predominant household smokers. Younger children and children with depressed and stressed caregivers are at significant risk of smoke exposures, even when a household smoking ban is reported. Further advocacy for these high-risk children is needed to help caregivers quit and to mitigate smoke exposure.
