In their study in this issue of the Journal, Heaney and colleagues (pp. 454-464) assert that profiling of fractional exhaled nitric oxide (FENO), blood eosinophil response, and adherence to inhaled corticosteroid/long-acting ß-agonist (ICS/LABA) therapy can identify those requiring biologic treatment (4). To evaluate adherence, the investigators used a novel and clever acoustic monitoring technology that time stamps a sound file, which can then be analyzed to determine adherence with inhaled medication (Inhaler Compliance Assessment [5]). Heaney and colleagues introduce the possibility of developing a clinically helpful, standardized protocol for evaluating adherence and inflammation control that can differentiate those patients who should be placed on a biologic medication from those whose inadequate symptom control may be a result of nonadherence rather than ICS/LABA failure (4).

Asthma is the most common childhood illness and disproportionately affects low-income, minority children who live in urban areas. A range of risk factors are associated with asthma morbidity and mortality, such as treatment non-adherence, exposure to environmental triggers, low-income households, exposure to chronic stress, child psychological problems, parental stress, family functioning, obesity, physical inactivity, and unhealthy diets. These risk factors often have complex interactions and inter-relationships. Comprehensive studies that explore the inter-relationships of these factors in accounting for asthma morbidity and mortality are needed and would help to inform clinical intervention. Considerable research has focused on interventions to improve adherence, asthma management, asthma symptoms, and quality of life for patients with asthma. Educational interventions combined with psychosocial interventions, such as behavioral, cognitive-behavioral, or family interventions, are beneficial and provide care in schools, homes, and emergency rooms can help to address barriers to accessing care for children and families. Additional recent research has explored the use of multidisciplinary, collaborative, integrated care with pediatric asthma patients, providing promising results. Integrated care could be ideal for addressing the multitude of complex psychosocial and wellness factors that play a role in childhood asthma, for increasing patient-centered care, and for promoting collaborative patient-provider relationships. Further research in this area is essential and would be beneficial.

Digital health interventions have been associated with reduced rescue inhaler use and improved controller medication adherence. This quality improvement project assessed the benefit of these interventions on asthma-related healthcare utilizations, including hospitalizations, emergency department (ED) utilization and outpatient visits. The intervention consisted of electronic medication monitors (EMMs) that tracked rescue and controller inhaler medication use, and a digital health platform that presented medication use information and asthma control status to patients and providers. In 224 study patients, the number of asthma-related ED visits and combined ED and hospitalization events 365 days pre- to 365 days post-enrollment to the intervention significantly decreased from 11.6 to 5.4 visits (p < 0.05) and 13.4 to 5.8 events (p < 0.05) per 100 patient-years, respectively. This digital health intervention was successfully incorporated into routine clinical practice and was associated with lower rates of asthma-related hospitalizations and ED visits.

It is well known that depression is associated with asthma symptoms. We assessed the combined effects of genetic factors and depression on asthma symptom severity using Bayesian network (BN) analysis. The common 100 top-ranked single-nucleotide polymorphisms (SNPs) were obtained from two genome-wide association studies of symptom severity in two childhood asthmatics trials (CAMP (Childhood Asthma Management Program) and CARE (Childhood Asthma Research and Education)). Using SNPs plus five discretized variables (depression, anxiety, age, sex, and race), we performed BN analysis in 529 CAMP subjects. We identified two nodes (depression and rs4672619 mapping to ERBB4 (Erb-B2 receptor tyrosine kinase 4)) that were within the Markov neighborhood of the symptom node in the network and then evaluated the interactive effects of depressive status and rs4672619 genotypes on asthma symptom severity. In childhood asthmatics with homozygous reference alleles, severe depression was related to less severe symptoms. However, in childhood asthmatics with heterozygous alleles and homozygous variant alleles, depression and symptom severity showed a positive correlation (interaction permutation P value = 0.019). We then tried to evaluate whether the interactive effects that we found were sustained in another independent cohort of elderly asthmatics. Contrary to the findings from childhood asthmatics, elderly asthmatics with homozygous reference alleles showed a positive correlation between depression and symptom severity, and elderly asthmatics with heterozygous alleles and homozygous variant alleles showed a negative correlation (interaction permutation P value = 0.003). In conclusion, we have identified a novel SNP, rs4672619, that shows interactive effects with depression on asthma symptom severity in childhood and elderly asthmatics in opposite directions. Asthma: How genetic factors and depression affect symptom severity A novel mutation affects how depression influences the severity of asthma symptoms, with opposite effects in children and the elderly. Depression is known to affect the severity of symptoms experienced by patients with chronic disorders, such as asthma. Heung-Woo Park at Seoul National University College of Medicine in South Korea and coworkers investigated how genetic factors might influence the interaction between depression and asthma. Using previously collected genetic data, the researchers identified a mutation linked with both asthma and depression. In children with the mutation, depression was linked to severe asthma symptoms; children with depression but without the mutation experienced milder symptoms. The researchers observed the opposite relationship in a group of elderly patients with asthma. They conclude that further study of this mutation could illuminate ways to improve asthma management strategies.

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.

Risk behaviors, including tobacco, alcohol, and drug use, are common in adolescents and young adults. Those who engage in one risk behavior are likely to engage in additional health risk behaviors, and as the number of risk behaviors increase, depression comorbidity emerges. For young people with chronic illness, risk behavior and depression are also common. There is some evidence that both depression and risk behavior are associated with nonadherence to medications, poor treatment outcomes, and death. The relationship between depression and asthma may involve more than one causal pathway and includes the possibility that depression can lead to a sense of hopelessness that erodes adherence and other health-promoting behavior, or that depression impacts asthma directly by altering the immune system. An assessment of the interplay between risk behavior, depression, adherence, and asthma can add important new information to our understanding about how to identify and treat those at greatest risk for poorly controlled disease and asthma-related death. New behavioral studies must overcome the shortcomings frequently seen in previous research and include well-designed and controlled investigations using valid behavioral measures of risk behavior, mood disorder, and adherence; recruitment that includes sufficient numbers of subjects and gives careful consideration of selection bias; and employment of multivariate data modeling to allow for simultaneous statistical examination of multiple relationships.

Background Much has been written about how the medical home model can enhance patient-centeredness, care continuity, and follow-up, but few comprehensive aids or resources exist to help practices accomplish these aims. The complexity of primary care can overwhelm those concerned with quality improvement. Methods The RE-AIM planning and evaluation model was used to develop a multimedia, multiple-health behavior tool with psychosocial assessment and feedback features to facilitate and guide patient-centered communication, care, and follow-up related to prevention and self-management of the most common adult chronic illnesses seen in primary care. Results The Connection to Health Patient Self-Management System, a web-based patient assessment and support resource, was developed using the RE-AIM factors of reach ( e.g ., allowing input and output via choice of different modalities), effectiveness ( e.g ., using evidence-based intervention strategies), adoption ( e.g ., assistance in integrating the system into practice workflows and permitting customization of the website and feedback materials by practice teams), implementation ( e.g ., identifying and targeting actionable priority behavioral and psychosocial issues for patients and teams), and maintenance/sustainability ( e.g ., integration with current National Committee for Quality Assurance recommendations and clinical pathways of care). Connection to Health can work on a variety of input and output platforms, and assesses and provides feedback on multiple health behaviors and multiple chronic conditions frequently managed in adult primary care. As such, it should help to make patient-healthcare team encounters more informed and patient-centered. Formative research with clinicians indicated that the program addressed a number of practical concerns and they appreciated the flexibility and how the Connection to Health program could be customized to their office. Conclusions This primary care practice tool based on an implementation science model has the potential to guide patients to more healthful behaviors and improved self-management of chronic conditions, while fostering effective and efficient communication between patients and their healthcare team. RE-AIM and similar models can help clinicians and media developers create practical products more likely to be widely adopted, feasible in busy medical practices, and able to produce public health impact.

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.
