Association between sleep disorders and health care utilization in children with chronic medical conditions: a Medicaid claims data analysis

STUDY OBJECTIVES

To examine the risk of increased health care utilization (HU) linked to individual sleep disorders in children with chronic medical conditions.

METHODS

Medicaid claims data from a cohort of 16,325 children enrolled in the Coordinated Healthcare for Complex Kids (CHECK) project were used. Sleep disorders and chronic medical conditions were identified using International Classification of Diseases, Ninth, and 10th Revision, codes. Three HU groups were identified based on participants' prior hospitalizations and emergency department (ED) visits in the 12 months prior to enrollment: low (no hospitalization or ED visit), medium (1-2 hospitalizations or 1-3 ED visits), and high (≥ 3 hospitalizations or ≥ 4 ED visits). The odds of being in an increased HU group associated with specific sleep disorders after controlling for confounding factors were examined.

RESULTS

Children with chronic medical conditions and any sleep disorder had nearly twice the odds (odds ratio = 1.83; 95% confidence interval: 1.67-2.01) of being in an increased HU group compared with those without a sleep disorder. The odds of being in the increased HU group varied among sleep disorders. Only sleep-disordered breathing (odds ratio = 1.51; 95% confidence interval : 1.17-1.95), insomnia (odds ratio = 1.46; 95% confidence interval : 1.06-2.02), and circadian rhythm sleep disorder (odds ratio = 2.45; 95% confidence interval : 1.07-5.64) increased those odds. Younger age and being White were also linked to increased HU.

CONCLUSIONS

Sleep disorders are associated with increased risk of heightened HU (ED visits and/or hospitalizations) in children with chronic medical conditions. This risk varies by specific sleep disorders. These findings indicate the need for careful evaluation and management of sleep disorders in this high-risk cohort.

Ethnic variation in asthma healthcare utilisation and exacerbation: systematic review and meta-analysis

Background

Patients from ethnic minority groups (EMGs) frequently report poorer asthma outcomes; however, a broad synthesis summarising ethnic disparities is yet to be undertaken. What is the magnitude of ethnic disparities in asthma healthcare utilisation, exacerbations and mortality?

Methods

MEDLINE, Embase and Web of Science databases were searched for studies reporting ethnic variation in asthma healthcare outcomes (primary care attendance, exacerbation, emergency department (ED) visits, hospitalisation, hospital readmission, ventilation/intubation and mortality) between White patients and those from EMGs. Estimates were displayed using forest plots and random-effects models were used to calculate pooled estimates. We conducted subgroup analyses to explore heterogeneity, including by specific ethnicity (Black, Hispanic, Asian and other).

Results

65 studies, comprising 699 882 patients, were included. Most studies (92.3%) were conducted in the United States of America (USA). Patients from EMGs had evidence suggestive of lower levels of primary care attendance (OR 0.72, 95% CI 0.48-1.09), but substantially higher ED visits (OR 1.74, 95% CI 1.53-1.98), hospitalisations (OR 1.63, 95% CI 1.48-1.79) and ventilation/intubation (OR 2.67, 95% CI 1.65-4.31) when compared to White patients. In addition, we found evidence suggestive of increased hospital readmissions (OR 1.19, 95% CI 0.90-1.57) and exacerbation rates (OR 1.10, 95% CI 0.94-1.28) among EMGs. No eligible studies explored disparities in mortality. ED visits were much higher among Black and Hispanic patients, while Asian and other ethnicities had similar rates to White patients.

Conclusions

EMGs had higher secondary care utilisation and exacerbations. Despite the global importance of this issue, the majority of studies were performed in the USA. Further research into the causes of these disparities, including whether these vary by specific ethnicity, is required to aid the design of effective interventions.

Poorer Caregiver Mental and Social Health Is Associated With Worse Respiratory Outcomes in Preschool Children With Recurrent Wheezing

BACKGROUND

Mental and social health in caregivers of preschool children has been inadequately studied, but it may influence respiratory symptom recognition and management.

OBJECTIVE

To identify preschool caregivers at highest risk for poor mental and social health outcomes on the basis of patient-reported outcome measures.

METHODS

Female caregivers 18 to 50 years old (N = 129) with a preschool child aged 12 to 59 months with recurrent wheezing and at least 1 exacerbation in the previous year completed 8 validated patient-reported outcome measures of mental and social health. k-means cluster analysis was performed using the T score for each instrument. Caregiver/child dyads were followed for 6 months. Primary outcomes included caregiver quality of life and wheezing episodes in their preschool children.

RESULTS

Three clusters of caregivers were identified: low risk (n = 38), moderate risk (n = 56), and high risk (n = 35). The high-risk cluster had the lowest life satisfaction, meaning and purpose, and emotional support and the highest social isolation, depression, anger, perceived stress, and anxiety that persisted for more than 6 months. This cluster had the poorest quality of life and marked disparities in social determinants of health. Preschool children from caregivers in the high-risk cluster had more frequent respiratory symptoms and a higher occurrence of any wheezing episode, but a lower outpatient physician utilization for wheezing management.

CONCLUSIONS

Caregiver mental and social health is associated with respiratory outcomes in preschool children. Routine assessment of mental and social health in caregivers is warranted to promote health equity and improve wheezing outcomes in preschool children.

Environmental justice and allergic disease: A Work Group Report of the AAAAI Environmental Exposure and Respiratory Health Committee and the Diversity, Equity and Inclusion Committee

Environmental justice is the concept that all people have the right to live in a healthy environment, to be protected against environmental hazards, and to participate in decisions affecting their communities. Communities of color and low-income populations live, work, and play in environments with disproportionate exposure to hazards associated with allergic disease. This unequal distribution of hazards has contributed to health disparities and is largely the result of systemic racism that promotes segregation of neighborhoods, disinvestment in predominantly racial/ethnic minority neighborhoods, and discriminatory housing, employment, and lending practices. The AAAAI Environmental Exposure and Respiratory Health Committee and Diversity, Equity and Inclusion Committee jointly developed this report to improve allergy/immunology specialists' awareness of environmental injustice, its roots in systemic racism, and its impact on health disparities in allergic disease. We present evidence supporting the relationship between exposure to environmental hazards, particularly at the neighborhood level, and the disproportionately high incidence and poor outcomes from allergic diseases in marginalized populations. Achieving environmental justice requires investment in at-risk communities to increase access to safe housing, clean air and water, employment opportunities, education, nutrition, and health care. Through policies that promote environmental justice, we can achieve greater health equity in allergic disease.

Long-term predictors of loss of asthma control in school-aged well-controlled children with mild to moderate asthma: A 5-year follow-up

BACKGROUND

Long-term follow-up studies establishing risk factors for loss of asthma control in well-controlled children with mild to moderate disease are lacking and are of importance for improving patient quality of life and utilization of health-care resources.

METHODS

Loss of asthma control was assessed in 146 school-aged children with well-controlled mild to moderate asthma from a Danish pediatric asthma outpatient clinic based on hospital admissions, emergency department (ED), or outpatient management of exacerbations, oral corticosteroid (OCS) use, or step-up of regular asthma treatment according to Global Initiative for Asthma (GINA) guidelines through a 5-year follow-up period. Risk factors included sex, ethnicity, age, body mass index (BMI), atopic comorbidity and predisposition, lung function, fractional exhaled nitric oxide (FeNO) level, exercise challenge test results, regular physical activity, GINA treatment step at baseline, and adherence to controller therapy.

RESULTS

A total of 27 (18%) children experienced 56 acute events defined by hospital admission, ED, or outpatient management. Risk of experiencing any acute event was increased with female sex (adjusted odds ratio, aOR = 2.4 (1.0-5.9), p = 0.047) and higher baseline GINA treatment step (aOR = 1.6 (1.1-2.5), p = 0.03). Furthermore, female sex (aOR = 6.1 (1.4-42.2), p = 0.01) and higher FeNO (aOR = 1.8 (1.0-3.2), p = 0.04) were associated with OCS prescriptions, whereas no risk factors were identified for GINA treatment step-up during the 5-year follow-up.

CONCLUSIONS

Female sex, higher FeNO, and higher baseline GINA treatment step increase the risk of long-term loss of control including acute events and OCS use in well-controlled children with mild to moderate asthma. These findings are important for primary physicians and clinicians in asthma outpatient clinics to identify seemingly well-controlled children at risk to plan more frequent follow-ups.

Evaluation of a Program to Reduce Home Environment Risks for Children with Asthma Residing in Urban Areas

Pediatric asthma morbidity is often linked to challenges including poor housing quality, inability to access proper medical care, lack of medications, and poor adherence to medical regimens. Such factors also propagate known disparities, by race and income, in asthma-related outcomes. Multimodal home visits have an established evidence base in support of their use to improve such outcomes. The Collaboration to Lessen Environmental Asthma Risks (CLEAR) is a partnership between the Cincinnati Children's Hospital Medical Center and the local health department which carries out home visits to provide healthy homes education and write orders for remediation should code violations and environmental asthma triggers be identified. To assess the strengths and weaknesses of the program, we obtained qualitative feedback from health professionals and mothers of children recently hospitalized with asthma using key informant interviews. Health professionals viewed the program as a positive support system for families and highlighted the potential benefit of education on home asthma triggers and connecting families with services for home improvements. Mothers report working to correct asthma triggers in the home based on the education they received during the course of their child's recent illness. Some mothers indicated mistrust of the health department staff completing home visits, indicating a further need for research to identify the sources of this mistrust. Overall, the interviews provided insights into successful areas of the program and areas for program improvement.

Allergic Comorbidity Is a Risk Factor for Not Attending Scheduled Outpatient Visits in Children with Asthma

Asthma is one of the most common chronic diseases in children globally. Previous studies have shown that not attending asthma primary care consultations is associated with poorer treatment adherence and increased risk of loss of asthma control on a short-term basis. Here, we investigated long-term patterns and predictors of not attending scheduled asthma outpatient visits during 5-years of follow-up in 146 children with asthma. Of the 146 children, 67 (46%) did not attend at least one scheduled appointment, amounting to a total of 122 (10.8%) missed of 1133 scheduled appointments. In a multivariate analysis adjusting for total scheduled visits in the 5-year period any allergic sensitization was a significant risk factor for not attending ≥1 scheduled appointment (aOR = 6.6 (95% CI, 1.3–39.7), p = 0.03), which was not the case for asthma treatment step or lung function. Furthermore, atopic predisposition decreased the risk of non-attendance (aOR = 0.36 (0.13–0.92), p = 0.04). We found no association between non-attendance, treatment adherence or loss of asthma control. This study highlights that allergic comorbidity, but not degree of asthma severity, identifies a group of children with asthma who are prone to not attend scheduled outpatient appointments.

Participant-level characteristics differ by recruitment setting when evaluating a behavioral intervention targeting adolescents with asthma

OBJECTIVE

The recruitment setting plays a key role in the evaluation of behavioral interventions. We evaluated a behavioral intervention for urban adolescents with asthma in three randomized trials conducted separately in three different settings over the course of 8 years. We hypothesized that characteristics of trial participants recruited from the ED and clinic settings would be significantly different from that of youth participating in the school-based trials. The intervention evaluated was Puff City, a web-based program that uses tailoring to improve asthma management behaviors.

METHODS

The present analysis includes youth aged 13-19 years who reported a physician diagnosis of asthma and symptoms at trial baseline. In the three trials, all participants were randomized post-baseline to a web-based, tailored intervention (treatment) or generic web-based asthma education (control).

RESULTS

Compared to school-based trial participants, ED participants had significantly more acute-care visits for asthma (p < 0.001) and more caregiver depression (p < 0.001). Clinic-based participants were more likely to have computer/ internet access than participants from the school-based trial (p < 0.001). Both ED and clinic participants were more likely to report controller medication (p's < 0.001) and higher teen emotional support (p's < 0.01) when compared to the schools, but were less likely to report Medicaid (p's < 0.014) and exposure to environmental tobacco smoke (p < 0.001).

CONCLUSION

Compared to participants in the school-based trials, participants recruited from ED and clinic settings differed significantly in terms of healthcare use, as well as psychosocial and sociodemographic factors. These factors can inform intervention content, and may impact external validity of behavioral interventions for asthma.

Asthma-Related Emergency Department Visits Among Low-Income Families With Young Children by Race/Ethnicity and Primary Language

OBJECTIVE

The aim of this study was to examine the existence of racial/ethnic and language disparities in asthma-related emergency department (ED) initial and return visits among young children in low-income families in California.

METHODS

Children younger than 6 years with at least 1 asthma-related ED visit recorded in the California Office of Statewide Health Planning and Development data set between January 1, 2009, and December 31, 2013, and on Medicaid (Medi-Cal) were assessed. Primary outcomes were hospitalization at the first asthma-related ED visit and a return asthma-related ED visit within 12 months. Data were analyzed using multivariate logistic regression.

RESULTS

Among 47,657 children, approximately 55% were Hispanic, 20% were black, and 2.7% were Asian/Pacific Islander. For non-English-speaking families, 82% were Hispanic. Among English-speaking families, blacks were less likely to be hospitalized at the first ED visit (odds ratio [OR], 0.787; 95% confidence interval [CI], 0.715-0.866) but more likely to return to the ED (OR, 1.291; 95% CI, 1.205-1.383) compared with whites. Conversely, Asian/Pacific Islanders whose primary language was English were more likely to be hospitalized (OR, 2.150; 95% CI, 1.827-2.530) compared with whites. Among families whose primary language was not English, Hispanic and Asian/Pacific Islanders are more likely to be hospitalized at the first ED visit and all groups are less likely to return to the ED compared with English-speaking whites.

CONCLUSIONS

The findings suggest that racial/ethnic and language disparities exist in eventual asthma-related hospitalizations and repeat ED visits. Continued research is needed to understand the existence of these differences and to inform future comprehensive and linguistically appropriate asthma interventions for children in low-income families.

Change of address as a measure of housing insecurity predicting rural emergency department revisits after asthma exacerbation

OBJECTIVE

Housing insecurity is an important socioeconomic factor that may impact emergency department (ED) use for children with asthma, but housing insecurity screening has primarily relied on patient surveys or linkage to external data sources. Using patient addresses recorded in the electronic medical record (EMR), we sought to correlate recent changes in address (as a proxy for housing insecurity) with ED revisit risk.

METHODS

We retrospectively identified patients age 2-17 years seen in our rural ED for asthma exacerbation during 2016-2018. We used EMR data from the 12 months before the earliest ED visit to compare patients with and without a recent change of address (over previous 12 months) on 30- and 90-day all-cause and asthma-specific ED revisits.

RESULTS

The study included 632 children, of whom 85 (13%) had a recent address change before the index ED visit. Moving was not associated with asthma-specific 30-day or 90-day revisits. Ninety-day all-cause revisits were more common among patients who had recently moved (36% vs. 25%; p = 0.019), although this difference was not statistically significant after multivariable adjustment for Medicaid insurance coverage and number of recent health system encounters (odds ratio: 1.49; 95% confidence interval: 0.91, 2.46; p = 0.114).

CONCLUSIONS

A history of recent address change in the EMR was not independently associated with repeat ED visits for asthma exacerbation. Many children presenting to the ED did not have recent encounters with our health system where address could be ascertained. This EMR-based proxy for housing insecurity may be more applicable to patients under continuous follow-up.

Prevalence and Predictors of Uncontrolled Asthma in Children Referred for Asthma and Other Atopic Diseases

Background

Uncontrolled asthma in children is still highly prevalent despite the availability of effective asthma treatment. We investigated 1) the prevalence of uncontrolled asthma among children referred for asthma and referred for atopic diseases other than asthma (ie food allergy, allergic rhinitis or atopic dermatitis) to secondary care; and 2) the predictors associated with uncontrolled asthma.

Methods

All children (4 to 18 years) referred for asthma or atopic diseases other than asthma to 8 secondary care centers in The Netherlands were invited to an electronic portal (EP). The EP is a web-based application with several validated questionnaires including the ISAAC questionnaires and the Asthma Control Test (ACT). Children were eligible for inclusion in this study when their parents reported in the EP that their child had asthma diagnosed by a physician. The ACT was used to assess asthma control. Multiple predictors of asthma control (patient, asthma and atopic characteristics) were evaluated by univariable and multivariable logistic regression analyses.

Results

We included 408 children: 259 children (63%) with asthma referred for asthma and 149 children (37%) with asthma referred for atopic diseases other than asthma. Thirty-nine percent of all children had uncontrolled asthma: 47% of the children referred for asthma and 26% of the children referred for atopic diseases other than asthma. Predictors associated with uncontrolled asthma were a family history of asthma (odds ratio [OR] 2.08; 95% confidence interval [95% CI] 1.34 to 3.24), and recurrent upper and lower respiratory tract infections in the past year (OR 2.40; 95% CI 1.52 to 3.81 and OR 2.00; 95% CI 1.25 to 3.23, respectively).

Conclusion

Uncontrolled asthma is highly prevalent in children with asthma referred to secondary care, even if children are primarily referred for atopic diseases other than asthma. Thus, attention should be paid to asthma control in this population.

Children with poorly controlled asthma: Randomized controlled trial of a home-based environmental control intervention

BACKGROUND

Few trials have tested targeted environmental control (EC) interventions based on biomarkers of second hand smoke (SHS) exposure and allergen sensitization in reducing asthma emergency department (ED) visits in children with poorly controlled asthma.

METHODS

Overall, 222 children with poorly controlled asthma were randomized into a home-based EC intervention (INT) or control (CON) group and followed for ED visits over 12 months. All children received allergen-specific IgE serologic testing and SHS exposure biomarker testing to inform the EC intervention. Pharmacy data was examined for asthma medication fills. Cox proportional hazards and multivariate regression models were performed to examine factors associated with repeat ED visits.

RESULTS

There was no difference in increased risk of >1 ED visit at 12 months between INT and CON groups. Most children (75%) had moderate/severe persistent asthma. Over half (56%) had SHS exposure and 83% tested positive for >1 allergen sensitization. Among children without SHS exposure, the median time to first recurrent ED visit differed by group (CON: 195; INT: >365 days) after adjusting for child age, allergic sensitization, medication fills prior to baseline, controller medication use, and the interaction between group status and SHS exposure. Children who had positive allergic sensitizations, younger, had increased controller medication use and randomized to the CON group and had no SHS exposure had increased risk for a repeat ED visit over 12 months.

CONCLUSIONS

In this study, a home-based EC intervention was not successful in reducing asthma ED revisits in children with poorly controlled asthma with SHS exposure. Allergic sensitization, young age, and increased controller medication use were important predictors of asthma ED visits.
