RESUMEN
The goal of asthma guideline therapy is to achieve disease control, by minimizing impairment and decreasing the risk of exacerbations and adverse effects of the disease and its treatment. The primary objective of most clinical trials of biologics for severe asthma is a reduction in exacerbation rate. Recently, studies with patients at the lower guideline steps have also selected exacerbation reduction as a primary objective. These trials in patients with milder disease frequently demonstrate statistically significantly fewer exacerbations, but their power calculations reflect larger sample size and smaller effect size. Exacerbations have a precise consensus definition, although a minimal clinically important difference has not been established. Reduction of exacerbations in severe asthma is commonly 10-fold greater than in mild disease. Further, reduction in exacerbations is not always associated with reduced impairment. If superior control is the objective, both domains should demonstrate consistent and parallel improvement. The disconnect may reflect the need for alternative tools for measurement of impairment or, possibly, different therapeutic mechanisms of action. Determining response to biologics or discussion of disease remission requires assessing symptoms that may occur daily rather than focusing on exacerbations that occur once or twice a year for patients at the highest steps of care according to the guidelines.

BACKGROUND: Patients with asthma and chronic obstructive pulmonary disease (COPD) may be prescribed once- or twice-daily dosing of controller inhalers. OBJECTIVE: To assess differences in controller adherence by dosing schedule and age. METHODS: Electronic medication monitors (EMMs) captured the date and time of inhaler actuations over 90 days in patients using the Propeller Health platform. Prescribed inhaler schedule was self-reported. Once- versus twice-daily schedule comparisons were assessed retrospectively using regressions adjusting for age. RESULTS: A total of 6294 patients with asthma and 1791 patients with COPD were included. On average, once-daily users had significantly higher median (interquartile range [IQR]) daily adherence than twice-daily users (asthma: 63.3 [IQR: 31.1, 86.7]% vs 50.3 [IQR: 21.1, 78.3]%, P < .001; COPD: 83.3 [IQR: 57.2, 95.6]% vs 64.7 [IQR: 32.8, 88.9]%, P < .001). This pattern persisted in all age groups, with the exception of 4- to 17-year-olds in asthma. The lowest adherence was in the young adult population (18- to 29-year-olds). The percentage of patients who achieved ≥80% adherence was significantly higher among once- versus twice-daily users in asthma (34.3% vs 23.6%, P < .001) and COPD (54.8% vs 38.6%, P < .001). The adjusted odds of once- versus twice-daily users achieving ≥80% adherence was 1.36 (95% confidence interval: 1.19-1.56, P < .001) in asthma and 1.73 (95% confidence interval: 1.38-2.17, P < .001) in COPD. Most once-daily patients with COPD took their medication in the morning versus at night; there was no difference in morning versus afternoon/evening administration in all other asthma and COPD groups. CONCLUSION: Patients with asthma and COPD who were prescribed once-daily versus twice-daily medications were more likely to adhere to their inhalers. Patients with COPD had higher adherence than those with asthma, possibly reflecting, in part, the older cohort age. The effect of greater adherence on exacerbations is a topic for future analysis.

OBJECTIVE: Current standard of care, patient self-report and clinician estimation, overestimates true inhaled corticosteroids (ICS) adherence. We compare self-reported inhaled ICS and short-acting beta 2-agonists (SABA) use with objective data from electronic medication monitors (EMMs). METHODS: Adults with uncontrolled asthma and prescribed ICS and SABA were enrolled. At visit one, participants' ICS and SABA inhalers were fitted with EMMs to track real-time medication usage over 14 days. Participants were asked to complete paper diaries to self-report medication usage over the same period. Participant self-report of ICS adherence and SABA use versus objective ICS adherence and SABA use was compared using Wilcoxon signed-rank tests. RESULTS: One hundred participants (80% female, mean age 48.5 years, 60% completed college, 80% privately insured) had complete data. Participant self-report (median (IQR): 0.8 (0.0, 2.0)) was greater than objectively measured (median (IQR): 0.43 (0.1, 2.1)) SABA use, but the difference was not statistically significant (P = 0.64). Participant self-report (median (IQR): 97 (67, 100)) was significantly greater than objectively measured (median (IQR): 75 (54, 93)) ICS adherence (P = 0.002). CONCLUSIONS: Significant discrepancies between self-report and objective ICS usage were observed. EMM can provide clinicians with accurate data on ICS medication taking behavior, thus reducing medication regimen complexity, side effects, and costs.

Digital health tools can promote disease self-management, but the association of smartphone app engagement and medication adherence is unclear. We assessed the relationship between objective smartphone app engagement and controller medication use in adults with asthma and COPD. We retrospectively analyzed data from participants enrolled in a digital self-management platform for asthma and COPD. Eligible adults had a smartphone and a paired electronic medication monitor (EMM). Longitudinal, mixed-effects logistic regressions estimated the relationship between daily app engagement (app opens, session duration) and daily controller medication use. Data from 2309 participants (71% asthma; 29% COPD) was analyzed. Opening the app (vs. not opening the app) was associated with significantly greater odds (OR (95% CI)) of using controller medications in asthma (2.08 (1.98, 2.19)) and COPD (1.61 (1.49, 1.75). Longer session duration was also associated with greater odds of using controller medications in asthma and COPD, but the odds of use attenuated with longer session duration in COPD. This study presents a novel assessment of the relationship between objectively-measured smartphone app engagement and controller medication use in asthma and COPD. Such insights may help develop targeted digital health tools and interventions.

Background: The COPD assessment test (CAT) is an 8-item questionnaire widely used in clinical practice to assess patient burden of disease. Digital health platforms that leverage electronic medication monitors (EMMs) are used to track the time and date of maintenance and short-acting beta-agonist (SABA) inhaler medication use and record patient-reported outcomes. The study examined changes in CAT and SABA inhaler use in COPD to determine whether passively collected SABA and CAT scores changed in a parallel manner. Methods: Patients with self-reported COPD enrolled in a digital health program, which provided EMMs to track SABA and maintenance inhaler use, and a companion smartphone application ("app") to provide medication feedback and reminders. Patients completing the CAT questionnaire in the app at enrollment and at 6 months were included in the analysis. Changes in CAT burden category [by the minimally important difference (MID)] and changes in EMM-recorded mean SABA inhaler use per day were quantified at baseline and 6 months. Results: The analysis included 611 patients. At 6 months, mean CAT improved by -0.9 (95% CI: -1.4, -0.4; p < 0.001) points, and mean SABA use decreased by -0.6 (-0.8, -0.4; p < 0.001) puffs/day. Among patients with higher burden (CAT ≥ 21) at enrollment, CAT improved by -2.0 (-2.6, -1.4; p < 0.001) points, and SABA use decreased by -0.8 (-1.1, -0.6; p < 0.001) puffs/day. Conclusion: Significant and parallel improvement in CAT scores and SABA use at 6 months were noted among patients enrolled in a digital health program, with greater improvement for patients with higher disease burden.
RESUMEN
BACKGROUND: Electronic medication monitors (EMMs) are associated with decreased rescue inhaler use, symptom burden, and increased medication adherence in asthma. However, the use of EMMs in people with chronic obstructive pulmonary disease (COPD) using the ELLIPTA dry powder inhaler has not been studied. METHODS: This was an open-label, single-arm, prospective observational study of EMMs and associated application (app) use over 12 weeks and up to 24 weeks (April-October 2019) in people with self-reported COPD aged ≥40 years enrolled in the COPD Patient-Powered Research Network, using an ELLIPTA inhaler. The primary outcome was daily active use of the app over 12 weeks. Treatment adherence, rescue inhaler use, and participant satisfaction were assessed over the same period. RESULTS: Among the 122 participants, mean (standard deviation [SD]) proportion of days participants opened the app was 59.5% (31.4), 51.1% (33.5) and 41.3% (34.2) for Days 1-30, 31-60 and 61-90, respectively. Mean (SD) adherence to maintenance medication remained stable: 80.2% (22.7) and 79.9% (26.7) for Days 1-30 and 61-90, respectively. In participants using a rescue inhaler and EMM, mean (SD) rescue-free days increased from 18.5 (10.0; Days 1-30, n=51) to 21.4 (9.6; Days 61-90, n=48). Participants reported high levels of confidence in using the EMM, valued app reminders highly and reported high system satisfaction (mean [SD] scale: 1=low, 5=high; 4.6 [1.1], 4.3 [1.1] and 4.1 [1.1], respectively). CONCLUSIONS: Use of an ELLIPTA EMM with frequent app engagement, high participant satisfaction and decreased rescue medication use may aid COPD management.
RESUMEN
Adherence to prescribed medications for chronic respiratory disease is considered a keystone for successful management. There is little consensus, though, on how to measure adherence, what is optimal adherence, or the goals of appropriate medication utilization. These criteria may differ when studying medication utilization at the patient or population level. The role of consistent medication use in chronic respiratory disease is associated with better outcomes. Shared decision-making is one strategy to achieve appropriate levels of adherence that requires negotiation, compromise by both patient and provider. It also recognizes that both success and failure to achieve goals of adherence are shared. As such, we discuss the current understanding of adherence measures in respiratory disease and identify the need for more nuanced approaches to evaluate adherence to reach acceptable patient outcomes.

Background: Question 4 (Q4) of the Asthma Control Test (ACT) asks patients to report their SABA use over the prior 4 weeks, a criterion for evaluating the impairment domain of asthma control. Biases in recall may lead to a misclassification of asthma control and has implications for asthma control determination and management strategies.Objective: To correlate objective electronic-recorded short-acting beta-agonist (SABA) use with self-reported use via Q4 of the ACT.Methods: Patients ≥18 years of age with a self-reported diagnosis of asthma were enrolled in a digital health electronic medication monitoring (EMM) platform, which recorded the date and time of SABA actuations and prompted the completion of the ACT. The correlations between ACT Q4 responses and EMM-recorded SABA use were evaluated using Spearman's rank correlation coefficients.Results: 1,062 patients (mean age: 35.4 years, mean ACT: 16.3) were included in analyses. Higher Q4 scores, indicating lower SABA use, were moderately and negatively correlated with EMM-recorded SABA use (ρ = -0.59 [95% CI: -0.63, -0.54]). Thirty-five percent of patients underreported SABA use when comparing Q4 to EMM-recorded SABA use.Conclusions: While ACT Q4 and EMM-recorded use were moderately correlated, underreported SABA use on the ACT highlights the need for objective measures of SABA use in asthma control assessments. The use of EMM-recorded SABA data has the potential for clinicians to more accurately determine asthma control, guide changes to controller therapy, and estimate imminent exacerbation risk.

Suboptimal adherence to maintenance therapy contributes to poor asthma control and exacerbations. This study evaluated the effect of different elements of a connected inhaler system (CIS), comprising clip-on inhaler sensors, a patient-facing app and a healthcare professional (HCP) dashboard, on adherence to asthma maintenance therapy.This was an open-label, parallel-group, 6-month, randomised controlled trial in adults with uncontrolled asthma (asthma control test (ACT) score less than 20) on fixed-dose inhaled corticosteroids/long-acting ß-agonist maintenance therapy (n=437). All subjects received fluticasone furoate/vilanterol ELLIPTA dry-powder inhalers for maintenance and salbutamol/albuterol metered-dose inhalers for rescue, with a sensor attached to each inhaler. Participants were randomised to one of five CIS study arms (allocation ratio 1:1:1:1:1) reflecting the recipient of the data feedback from the sensors, as follows: 1) maintenance use to participants and HCPs (n=87); 2) maintenance use to participants (n=88); 3) maintenance and rescue use to participants and HCPs (n=88); 4) maintenance and rescue use to participants (n=88); and 5) no feedback (control) (n=86).For the primary endpoint, observed mean±sd adherence to maintenance therapy over months 4-6 was 82.2±16.58% (n=83) in the "maintenance to participants and HCPs" arm and 70.8±27.30% (n=85) in the control arm. The adjusted least squares mean±se was 80.9±3.19% and 69.0±3.19%, respectively (study arm difference: 12.0%, 95% CI 5.2-18.8%; p<0.001). Adherence was also significantly greater in the other CIS arms versus the control arm. The mean percentage of rescue medication free days (months 4-6) was significantly greater in participants receiving data on their rescue use compared with controls. ACT scores improved in all study arms with no significant differences between groups.A CIS can improve adherence to maintenance medication and reduce rescue medication use in patients with uncontrolled asthma.

BACKGROUND: Poor adherence to inhaled corticosteroids (ICSs) and overuse of short-acting beta2-agonists (SABAs) are associated with increased asthma morbidity. OBJECTIVE: To assess whether patient self-monitoring via electronic medication monitoring and smartphone application plus remote clinician feedback influences ICS and SABA use. METHODS: Adults with uncontrolled asthma and prescribed ICS and SABA were enrolled in this 14-week study. Inhalers were fitted with electronic medication monitoring to track real-time usage. After a 14-day baseline, participants were randomly assigned to the treatment group where they received reminders and feedback on ICS and SABA use via a smartphone application and clinician phone calls, or control group without feedback. Linear mixed models compared the baseline percentage of SABA-free days and ICS adherence to the last 14 study days. RESULTS: Participants (n = 100) had a mean age of 48.5 years, 80% were female, 68% white, and 80% privately insured. The percentage of SABA-free days increased significantly in the treatment group (19%; 95% CI, 12 to 26; P < .01) and nonsignificantly in the control group (6%, 95% CI, -3 to 16; P = .18), representing a 13% (95% CI, 1-26; P = .04) difference. ICS adherence changed minimally in the treatment group (-2%; 95% CI, -7 to 3; P = .40), but decreased significantly (-17%; 95% CI, -26 to -8; P < .01) in the control group, representing a 15% (95% CI, 4 to 25; P < .01) difference. CONCLUSIONS: Patient self-monitoring via a digital platform plus remote clinician feedback maintained high baseline ICS adherence and decreased SABA use.

Non-adherence to treatment regimens in asthma is well described, however less is known about temporal patterns of medication use. We monitored 20 weeks of controller medication use and analyzed these patterns in patients ≥4 years of age with self-reported asthma enrolled in a digital health program. At baseline, approximately 20%, 28%, 25% and 27% of patients had optimal, moderate, sub-optimal and poor adherence, respectively. Medication adherence decreased in all groups in this study. The largest absolute decreases in adherence (-32%) were observed for moderately adherent patients. Certain adherence patterns which demonstrated greater declines, that, once identified, could be intervened upon.

Asthma imposes tremendous burden on children, families, and society. Successful management requires coordinated care among children, families, health providers, and schools. Building Bridges for Asthma Care Program, a school-centered program to coordinate care for successful asthma management, was developed, implemented, and evaluated. The program consists of five steps: (1) identify students with asthma; (2) assess asthma risk/control; (3) engage the family and student at risk; (4) provide case management and care coordination, including engagement of health-care providers; and (5) prepare for next school year. Implementation occurred in 28 schools from two large urban school districts in Colorado and Connecticut. Significant improvements were noted in the proportions of students with completed School Asthma Care Plans, a quick-relief inhaler at school, Home Asthma Action/Treatment Plans and inhaler technique (p < .01 for all variables). Building Bridges for Asthma Care was successfully implemented extending asthma care to at-risk children with asthma through engagement of schools, health providers, and families.

BACKGROUND: Digital health programs assist patients with chronic obstructive pulmonary disease (COPD) to better manage their disease. Technological and adoption barriers have been perceived as a limitation. OBJECTIVE: The aim of the research was to evaluate a digital quality improvement pilot in Medicare-eligible patients with COPD. METHODS: COPD patients were enrolled in a digital platform to help manage their medications and symptoms as part of their routine clinical care. Patients were provided with electronic medication monitors (EMMs) to monitor short-acting beta-agonist (SABA) use passively and a smartphone app to track use trends and receive feedback. Providers also had access to data collected via a secure website and were sent email notifications if a patient had a significant change in their prescribed inhaler use. Providers then determined if follow-up was needed. Change in SABA use and feasibility outcomes were evaluated at 3, 6, and 12 months. RESULTS: A total of 190 patients enrolled in the pilot. At 3, 6, and 12 months, patients recorded significant reductions in daily and nighttime SABA use and increases in SABA-free days (all P<.001). Patient engagement, as measured by the ratio of daily active use to monthly active use, was >90% at both 6 and 12 months. Retention at 6 months was 81% (154/190). Providers were sent on average two email notifications per patient during the 12-month program. CONCLUSIONS: A digital health program integrated as part of standard clinical practice was feasible and had low provider burden. The pilot demonstrated significant reduction in SABA use and increased SABA-free days among Medicare-eligible COPD patients. Further, patients readily adopted the digital platform and demonstrated strong engagement and retention rates at 6 and 12 months.
RESUMEN
INTRODUCTION: The COPD Assessment Test (CAT) is a self-administered questionnaire that measures symptomatic burden. CAT is used as part of the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines refined ABCD tool and is usually performed during office visit assessment. Electronic medication monitors (EMMs) capture utilization of short-acting beta-agonists (SABA) that may indicate disease worsening in real-time. The primary objective was to assess the relationship of CAT with SABA utilization. METHODS: From 8/2017-1/2019, COPD patients ≥40 years of age were enrolled in a digital health platform consisting of EMMs and a mobile application to track time and date of SABA use. Patients with a completed CAT and ≥81 days of continuous EMM data were included in analyses. Using one-way ANOVA, SABA use and maintenance medication adherence were compared by CAT score categories: <10 (low burden), 10-20 (medium), 21-30 (high), and 31-40 (very high). Associations were additionally estimated in patients who used ≥1 puff/week of their rescue and maintenance medication. RESULTS: The population included 2196 COPD patients (mean age: 60 years). CAT scores from low to high burden were associated with greater SABA use, from 0.8 to 1.9 puffs/day (+1.1 [95% CI: 0.6, 1.6 puffs/day], Pâ¯<â¯0.001), and lower adherence, from 69% to 59%, (-10% [95% CI: -1, -19%], Pâ¯=â¯0.04). Sensitivity analyses yielded similar results. CONCLUSIONS: This study found a significant association between greater SABA use and lower adherence with higher burden CAT scores. This finding may suggest that passive collection of inhaled medications could serve as a surrogate for CAT.
