COVID-19 on the Navajo Nation: experiences of Diné families of children with asthma.

OBJECTIVE: The first case of COVID-19 on the Navajo Nation (NN) was found on March 17, 2020. Even with strong public health efforts, NN saw the highest per capita infection rate in the US during May of 2020 with 2450/100,000. To determine the impact of COVID-19 on families of children with asthma on the NN, families participating in the NHLBI funded Community Asthma Program were contacted to see if they would share their experiences. METHODS: Sixty-six of 193 families (34%) were interviewed.Results: The average age of the child with asthma was 13.5 (SD = 3.9) and 33% were female. Most Diné children with asthma in our study did not contract COVID-19. However, the pandemic had a significant impact on them and their families. Many family members contracted COVID-19, some children lost family members, and half of interviewed parents reported a decline in their child's mental health. Twenty-five percent of families sought the help of a traditional healer. Many accessed medical care through telehealth and most were able to obtain asthma medications when needed.Conclusions: Despite significant challenges, our research indicated resilience among Navajo families.

Informing Healthcare Decisions with Observational Research Assessing Causal Effect. An Official American Thoracic Society Research Statement.

Rationale: Decisions in medicine are made on the basis of knowledge and reasoning, often in shared conversations with patients and families in consideration of clinical practice guideline recommendations, individual preferences, and individual goals. Observational studies can provide valuable knowledge to inform guidelines, decisions, and policy.Objectives: The American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement to clarify the role of observational studies-alongside randomized controlled trials (RCTs)-in informing clinical decisions in pulmonary, critical care, and sleep medicine.Methods: The committee examined the strengths of observational studies assessing causal effects, how they complement RCTs, factors that impact observational study quality, perceptions of observational research, and, finally, the practicalities of incorporating observational research into ATS clinical practice guidelines.Measurements and Main Results: There are strengths and weakness of observational studies as well as RCTs. Observational studies can provide evidence in representative and diverse patient populations. Quality observational studies should be sought in the development of ATS clinical practice guidelines, and medical decision-making in general, when 1) no RCTs are identified or RCTs are appraised as being of low- or very low-quality (replacement); 2) RCTs are of moderate quality because of indirectness, imprecision, or inconsistency, and observational studies mitigate the reason that RCT evidence was downgraded (complementary); or 3) RCTs do not provide evidence for outcomes that a guideline committee considers essential for decision-making (e.g., rare or long-term outcomes; "sequential").Conclusions: Observational studies should be considered in developing clinical practice guidelines and in making clinical decisions.

Predicting Young Adult Tobacco, Drug and Alcohol Use Among Participants in the CAMP Trial.

The development of substance abuse in youth with asthma have seldom been examined with longitudinal research. The prospective and well-characterized CAMP cohort provides outcome data on youth with asthma over 13 years. This manuscript seeks to determine the contributions of asthma features and child behavioral/emotional functioning to subsequent tobacco, alcohol, and drug use in early adulthood. Childhood smoking exposures as well as parent report and youth report of substance use were prospectively assessed concurrently with assessments of asthma symptoms, study medication, and lung development. Logistic regression models evaluated predictors of adolescent and young adult tobacco, alcohol, and drug use. Use of tobacco products was reported by 33% of youth with mild/moderate asthma. Tobacco use was significantly associated with self-reported externalizing behaviors. Early life passive smoke exposure, especially in utero exposure, makes a significant contribution to tobacco use (OR1.58). Greater risk for tobacco use is conveyed by self-reported externalizing behaviors, which are consistently robust predictors of any future use of tobacco products, alcohol and drugs. These findings provide evidence for health care providers to use routine behavioral screening in youth with asthma.

Adults With Asthma Experience No Increase in Asthma-related Exacerbations When Digital Communication Technology Tools Are Employed to Offset Provider Workload: A Pragmatic Randomized Trial.

BACKGROUND: Challenges to health care efficiency are increasingly addressed with the help of digital communication technology tools (DCTs). OBJECTIVE: The objective of this study was to test whether DCT, compared with Usual Care, can reduce health care clinician burden without increasing asthma-related exacerbations among patients with asthma in a large integrated health care system. RESEARCH DESIGN: The (Breathewell) program was a pragmatic, randomized trial at (Kaiser Permanente Colorado), where asthma nurses screen patients for poor symptom control when beta2-agonist refill requests came within 60 days of previous fill or in the absence of a controller medication fill within 4 months (beta2-agonist overfill). A total of 14,978 adults with asthma were randomized to Usual Care or 1 of 2 DCT intervention groups (Text/Phone call or Email). SUBJECTS: Participants included adults 18 and older with an asthma diagnosis at the time of randomization and no history of chronic obstructive pulmonary disease. MEASURES: Primary outcome measures included asthma-related health care resource utilization (eg, asthma nurse contacts), medication use, and exacerbations. RESULTS: A total of 1933 patients had 4337 events which met beta2-agonist overfill criteria. Of the 2874 events in the intervention arm, 1188 (41%) were resolved by DCT contact and did not require additional clinician contact. Asthma medication use and exacerbations over 12 months did not differ among the 3 groups. CONCLUSIONS: DCT tools can successfully contact adult asthma patients to screen for symptoms and facilitate intervention. The absence of differences in medication fills and health care utilization indicates that the strategic replacement of nursing interventions by digital outreach did not reduce treatment adherence or compromise health care outcomes.

Shared decision making for the allergist.

OBJECTIVE: Shared decision making (SDM) is becoming more commonly appreciated and used in medical practice as a way to empower patients who are facing treatment preference-sensitive conditions, such as allergic rhinitis, atopic dermatitis, food allergy, and persistent asthma. The purpose of this review is to educate the allergy health care provider about how SDM works and provide practical advice and allergist-specific SDM resources. DATA SOURCES: PubMed and online patient decision aid resources. STUDY SELECTIONS: Studies and reviews relevant to SDM and patient decision aids relevant to the allergy health care provider were selected for discussion. RESULTS: There are ethical, practical, economic, and psychological imperatives for the implementation of quality SDM, particularly for chronic diseases. Many benefits and barriers of SDM have been identified and models have been developed to encourage implementation of quality SDM. For the allergy health care provider, SDM for asthma has been shown to improve adherence, outcomes, and patient satisfaction with care. Patient decision aids are useful tools for SDM and have recently been developed for allergen immunotherapy, severe asthma, and atopic dermatitis. CONCLUSION: Effective SDM has been shown to improve adherence and lead to better outcomes. SDM should be universally implemented as a key component of patient-centered health care. Allergy health care providers should work with their patients to reach treatment decisions that align with their values and preferences.

Digital technologies and adherence in respiratory diseases: the road ahead.

Outcomes for patients with chronic respiratory diseases remain poor despite the development of novel therapies. In part, this reflects the fact that adherence to therapy is low and clinicians lack accurate methods to assess this issue. Digital technologies hold promise to overcome these barriers to care. For example, algorithmic analysis of large amounts of information collected on health status and treatment use, along with other disease relevant information such as environmental data, can be used to help guide personalised interventions that may have a positive health impact, such as establishing habitual and correct inhaler use. Novel approaches to data analysis also offer the possibility of statistical algorithms that are better able to predict exacerbations, thereby creating opportunities for preventive interventions that may adapt therapy as disease activity changes. To realise these possibilities, digital approaches to disease management should be supported by strong evidence, have a solid infrastructure, be designed collaboratively as clinically effective and cost-effective systems, and reflect the needs of patients and healthcare providers. Regulatory standards for digital interventions and strategies to handle the large amounts of data generated are also needed. This review highlights the opportunities provided by digital technologies for managing patients with respiratory diseases.

Integrated behavioral health care for management of stress in allergic diseases.

OBJECTIVE: This article reviews current findings regarding the management of stress in allergic disease. DATA SOURCES: The authors use articles and books published between 1995 and 2017. Approximately 85% of sources used were published in the last 10 years, and 60% were published in the last 5 years. Most of the sources are peer-reviewed articles. STUDY SELECTIONS: Articles that focused on allergic diseases such as allergic rhinitis, food allergies, urticaria, and allergic asthma were included. Articles in which whether the underlying disorder was allergic in nature (for example, nonspecified asthma) were not included. Preference was given to articles published within the past five years. RESULTS: Patients with allergic diseases, particularly those with chronic or co-occurring allergic diseases, often experience stress and, in turn, this experience of stress can exacerbate disease presentation. High rates of treatment nonadherence in patients with allergic disease also can increase disease burden and stress. Research supports the benefit of behavioral health interventions for patients with allergic disease. Interventions with multidisciplinary teams, which include behavioral health, as well as interventions at the school, workplace, and community level, are recommended. CONCLUSION: Medical providers working with patients with allergic disease need to address patients' experience of stress and nonadherence to treatment recommendations. This could be done through routine screening and referrals to behavioral health or, ideally, through incorporation of a behavioral health provider within a multidisciplinary patient team.

Role of behavioral health in management of pediatric atopic dermatitis.

OBJECTIVE: To describe the behavioral components and complications in treating pediatric patients with atopic dermatitis (AD) and the critical role of behavioral health professionals in addressing disease impact and behavioral aspects of disease management for these patients and families. DATA SOURCES: Studies and review articles were selected from medical and psychology databases for relevance to pertinent topics. RESULTS: AD has significant negative effects in affected individuals and their families on quality of life, behavioral, emotional, and sleep disturbances, and family functioning. Effective treatment strategies for AD are available, but the challenges for children and parents in coping with disease-related concerns and in following through with the multiple aspects of treatment are considerable. A biopsychosocial model, which incorporates the interplay among biological, psychological, and social dimensions of medical care, can be implemented in various treatment settings to achieve an integrated medical and behavioral health care approach. By sharing a family orientation, using a stress and coping model, and taking into account children's developmental capabilities and concerns, medical and behavioral health care providers are equipped to bring an in-depth understanding and different evidence-based therapeutic tools to address emotional, behavioral, and interpersonal challenges imposed by moderate to severe AD in children and families. CONCLUSION: Behavioral health and medical providers working together to provide integrated care play a critical role in helping children and families cope with the burdens imposed by AD, successfully manage the disease, and achieve optimal quality of life for affected children and their families.

Measuring the cost of poor asthma control and exacerbations.

BACKGROUND: Previous studies have shown an association between cost and poor asthma control. However, longitudinal studies of general populations are lacking. OBJECTIVE: To examine the cost of poor asthma control and exacerbations across a broad spectrum of asthma patients. METHODS: The Observational Study of Asthma Control and Outcomes (OSACO) was a prospective survey of persistent asthma patients in Kaiser Colorado in 2011-2012. Patients received a survey 3 times in one year, which included the Asthma Control Questionnaire (ACQ) and questions on exacerbations. Self-reported exacerbations were compared to actual oral corticosteroid (OCS) use. Regression analyses examined the association of control (ACQ-5 scores) and exacerbations with healthcare expenditures, controlling for sociodemographics and smoking. Analyses of expenditures used Generalized Linear Models (GLM) with log-link. RESULTS: 2681 individuals completed at least one survey; 1799 completed all three. ACQ-5 scores were associated with higher all-cause and asthma-specific expenditures across all categories of costs (medical, outpatient, ER, pharmacy) except for inpatient expenditures. Each 1-point increase in the ACQ-5 score (i.e., worse control) was associated with a corresponding increase in all-cause annual healthcare and asthma-specific expenditures of $1443 and $927 ($US 2013). Asthma exacerbations with documented OCS use were associated with an increase of $3014 and $1626 over 4 months, while self-reported exacerbations were $713 and $506. CONCLUSION: Results demonstrate that poor asthma control and exacerbations are strongly associated with higher healthcare expenditures. Results also confirm that collection of validated measures of control such as the ACQ-5 may provide valuable information toward improving clinical and economic outcomes.

An Official American Thoracic Society Research Statement: Implementation Science in Pulmonary, Critical Care, and Sleep Medicine.

BACKGROUND: Many advances in health care fail to reach patients. Implementation science is the study of novel approaches to mitigate this evidence-to-practice gap. METHODS: The American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement on implementation science in pulmonary, critical care, and sleep medicine. The committee used an iterative consensus process to define implementation science and review the use of conceptual frameworks to guide implementation science for the pulmonary, critical care, and sleep community and to explore how professional medical societies such as the ATS can promote implementation science. RESULTS: The committee defined implementation science as the study of the mechanisms by which effective health care interventions are either adopted or not adopted in clinical and community settings. The committee also distinguished implementation science from the act of implementation. Ideally, implementation science should include early and continuous stakeholder involvement and the use of conceptual frameworks (i.e., models to systematize the conduct of studies and standardize the communication of findings). Multiple conceptual frameworks are available, and we suggest the selection of one or more frameworks on the basis of the specific research question and setting. Professional medical societies such as the ATS can have an important role in promoting implementation science. Recommendations for professional societies to consider include: unifying implementation science activities through a single organizational structure, linking front-line clinicians with implementation scientists, seeking collaborations to prioritize and conduct implementation science studies, supporting implementation science projects through funding opportunities, working with research funding bodies to set the research agenda in the field, collaborating with external bodies responsible for health care delivery, disseminating results of implementation science through scientific journals and conferences, and teaching the next generation about implementation science through courses and other media. CONCLUSIONS: Implementation science plays an increasingly important role in health care. Through support of implementation science, the ATS and other professional medical societies can work with other stakeholders to lead this effort.

Exploring asthma control cutoffs and economic outcomes using the Asthma Control Questionnaire.

BACKGROUND: Understanding the effect of worsening asthma control on expenditures and health resource utilization (HRU) is important. OBJECTIVE: To explore the association of economic outcomes with asthma control cutoffs and longitudinal changes on the Asthma Control Questionnaire 5 (ACQ-5). METHODS: The Observational Study of Asthma Control and Outcomes was a survey of patients with persistent asthma who were patients of Kaiser Colorado, including claims-based HRU. Patients completed the ACQ-5 three times during 1 year between April 2011 and June 2012. The ACQ-5 cutoffs that indicated control were assessed in cross-sectional analyses. Longitudinal changes in control were explored: controlled (ACQ-5 score <0.75), indeterminate (ACQ-5 score 0.75 to <1.5), not well controlled (ACQ-5 score 1.5 to <3.0), and very poorly controlled (ACQ-5 score ≥3.0). Analyses used generalized linear models with log link (expenditures) and negative binomial regression (HRU). RESULTS: There were 6,666 completed surveys (1,799 individuals completed all 3 survey waves). In the cross-sectional analyses, compared with an ACQ-5 score less than 0.5, individuals with ACQ-5 scores of 4 to 4.5 incurred 7.2 times the number of oral corticosteroid prescriptions, 4.3 times the number of emergency department visits, 6 times the number of inpatient visits, 10.4 times the number of asthma-specific emergency department visits, 4.58 times the number of asthma-specific inpatient visits, and $2,892 more in all-cause and $1,877 in asthma-specific expenditures during 4 months. In the longitudinal change analyses, individuals who improved from an ACQ-5 of 3.0 or greater to less than 0.75 incurred $6,023 less in asthma-specific expenditures during 4 months than those remaining at an ACQ-5 score of 3.0 or higher. CONCLUSION: Results provide preliminary economic data on possible control cutoffs for the ACQ-5. Improving asthma control over time may result in significant savings that may justify financial investments designed to improve control.

Measurement of utility in asthma: evidence indicating that generic instruments may miss clinically important changes.

BACKGROUND: Accurate assessment of preference-based health-related quality of life is important in determining the value of asthma interventions. OBJECTIVE: To examine the sensitivity and responsiveness of the EQ-5D and the AQL-5D to differences in asthma control measured by the Asthma Control Questionnaire (ACQ-5). METHODS: The Observational Study of Asthma Control and Outcomes was a prospective survey of persistent asthma patients ≥12 years old in Kaiser Colorado. Patients received a survey three times in 1 year, including the ACQ-5, AQL-5D and EQ-5D-3L (including VAS). Censored Least Absolute Deviations (CLAD) and logistic regression were used, controlling for sociodemographics and smoking. RESULTS: There were 6666 completed surveys (1799 individuals completed all three survey waves). After controlling for covariates, each one-point increase in ACQ-5 was associated with a decrease of 0.066, 0.058, 0.074 and 6.12 in EQ-5D(US), EQ-5D(UK), AQL-5D and VAS scores. Uncontrolled asthma (ACQ-5 > 1.5) was associated with a decrease of 0.15, 0.17, 0.11 and 10, respectively (vs. ACQ ≤ 1.5). AQL-5D scores were statistically significantly different across categories of ACQ-5 scores of 0.5 (the minimum clinically important difference [MCID]), while EQ-5D scores were not significant across most categories. The AQL-5D appeared more robust to changes in control over time (responsiveness) compared to EQ-5D-3L. CONCLUSION: The AQL-5D appears more responsive to changes in asthma control over time and more sensitive to detecting differences corresponding to the ACQ-5 MCID than the EQ-5D-3L. Using the EQ-5D-3L without an asthma-specific measure such as the AQL-5D may miss clinically important changes in asthma control.

Future Research Directions in Asthma. An NHLBI Working Group Report.

Asthma is a common chronic disease without cure. Our understanding of asthma onset, pathobiology, classification, and management has evolved substantially over the past decade; however, significant asthma-related morbidity and excess healthcare use and costs persist. To address this important clinical condition, the NHLBI convened a group of extramural investigators for an Asthma Research Strategic Planning workshop on September 18-19, 2014, to accelerate discoveries and their translation to patients. The workshop focused on (1) in utero and early-life origins of asthma, (2) the use of phenotypes and endotypes to classify disease, (3) defining disease modification, (4) disease management, and (5) implementation research. This report summarizes the workshop and produces recommendations to guide future research in asthma.

Motivating patient adherence to allergic rhinitis treatments.

Patient nonadherence significantly burdens the treatment of allergic rhinitis (AR). Fewer than half of prescribed doses of intranasal corticosteroid medication are taken. The challenges for immunotherapies are even greater. While sustained treatment for 3 to 5 years is required for full benefit, most patients receiving immunotherapy, either subcutaneous or sublingual, stop treatment within the first year. Although research into interventions to improve AR adherence is lacking, lessons learned from adherence interventions in other chronic health conditions can be applied to AR. Two well-established, overriding models of care-the chronic care model and patient-centered care-can improve adherence. The patient-centered care model includes important lessons for allergy providers in their daily practice, including understanding and targeting modifiable barriers to adherence. Additionally, recent studies have begun to leverage health information and communication technologies to reach out to patients and promote adherence, extending patient-centered interventions initiated by providers during office visits.

Nonadherence in chronic obstructive pulmonary disease patients: what do we know and what should we do next?

PURPOSE OF REVIEW: Although nonadherence research in patients with chronic obstructive pulmonary disease (COPD) lags well behind other diseases, new evidence helps inform understanding about the degree and underlying causes of patient nonadherence, interventions that can improve adherence, and areas of research needed to further progress in improving this problem in patients with COPD. RECENT FINDINGS: Fewer than half of treatments for COPD, including oxygen supplementation, physical rehabilitation, and medication, are taken as prescribed. Most patients abandon their treatment after an initial start. Nonadherence in turn contributes to rising rates of hospitalization, death, and healthcare costs. The reasons why patients choose not to use their COPD treatments are not fully understood, although depression is clearly a contributing factor. Although a substantial number of studies have tested adherence interventions, few have included COPD patients or addressed polypharmacy in patients with multiple comorbidities. SUMMARY: The paucity of research does not reflect the inadequacy of available treatments. Lessons learned from the research outside of COPD and a small number of COPD studies suggest that a collaborative care approach will likely provide the most potential for improving overall care, including management of depression and enhancement of adherence. Exploitation of mobile telephone technology to engage patients in a discussion of their self-care should not be ignored as a potential intervention for COPD patients.

Factors associated with levels of adherence to inhaled corticosteroids in minority adolescents with asthma.

BACKGROUND: Nonadherence to inhaled corticosteroids (ICS) is a significant risk factor for poor asthma outcomes in minority adolescents with persistent asthma. OBJECTIVE: To identify factors associated with nonadherence to daily ICS in this target population. METHODS: Adolescents 11 to 16 years old, self-identified as African American or Hispanic, diagnosed with persistent asthma and with an active prescription for daily ICS were invited to participate. Participant adherence to ICS was electronically measured during 14 days. Concurrently, participants completed the following assessments: demographic information, asthma history, asthma control, asthma exacerbations, media use, depression, asthma knowledge, ICS knowledge, and ICS self-efficacy. Of the 93 subjects, 68 had low (<48%) adherence and 25 had high (>48%) adherence. RESULTS: Older age and low ICS knowledge each were associated with low (≤48%) adherence (P < .01 for the 2 variables). CONCLUSION: Older age and low ICS knowledge each may be associated with poor adherence to ICS in minority adolescents with persistent asthma. Although older age often is associated with the assignment of increased responsibility for medication-taking behavior, it may not be associated with increased adherence. Continued and expanded efforts at promoting asthma education and specifically knowledge of ICS may increase adherence to ICS.

The association of health literacy with adherence and outcomes in moderate-severe asthma.

BACKGROUND: Low health literacy is associated with poor outcomes in asthma and other diseases, but the mechanisms governing this relationship are not well defined. OBJECTIVE: We sought to assess whether literacy is related to subsequent asthma self-management, measured as adherence to inhaled steroids, and asthma outcomes. METHODS: In a prospective longitudinal cohort study, numeric (Asthma Numeracy Questionnaire) and print literacy (Short Test of Functional Health Literacy in Adults) were assessed at baseline in adults with moderate or severe asthma for their impact on subsequent electronically monitored adherence and asthma outcomes (asthma control, asthma-related quality of life, and FEV1) over 26 weeks, using mixed-effects linear regression models. RESULTS: A total of 284 adults participated: age, 48 ± 14 years, 71% females, 70% African American, 6% Latino, mean FEV1 66% ± 19%, 86 (30%) with hospitalizations, and 148 (52%) with emergency department visits for asthma in the prior year. Mean Asthma Numeracy Questionnaire score was 2.3 ± 1.2 (range, 0-4); mean Short Test of Functional Health Literacy in Adults score was 31 ± 8 (range, 0-36). In unadjusted analyses, numeric and print literacy were associated with better adherence (P = .01 and P = .08, respectively), asthma control (P = .005 and P < .001, respectively), and quality of life (P < .001 and P < .001, respectively). After controlling for age, sex, and race/ethnicity, the associations diminished and only quality of life (numeric P = .03, print P = .006) and asthma control (print P = .005) remained significantly associated with literacy. Race/ethnicity, income, and educational attainment were correlated (P < .001). CONCLUSION: While the relationship between literacy and health is complex, interventions that account for and address the literacy needs of patients may improve asthma outcomes.
