Project description:BackgroundIn adults and adolescents with asthma, use of ≥3 short-acting β2 -agonist (SABA) canisters/year is associated with increased exacerbation risk. Whether this association is present in younger children remains unknown. In this SABA use IN Asthma (SABINA) Junior study, we assessed the association of SABA collection with exacerbation risk in the general Swedish pediatric asthma population.MethodsThis population-based cohort study utilized linked data from the Swedish national healthcare registries involving patients with asthma (<18 years) treated in secondary care between 2006-2015. Exacerbation risk, by baseline SABA collection (0-2 vs. ≥3 canisters, further examined as ordinal/continuous variable) and stratified on comorbid atopic disease (allergic rhinitis, dermatitis and eczema, and food/other allergies), was assessed for 1-year follow-up using negative binomial regression.ResultsOf 219,561 patients assessed, 45.4%, 31.7%, and 26.5% of patients aged 0-5, 6-11, and 12-17 years, respectively, collected ≥3 SABA canisters during the baseline year (high use). Collection of ≥3 SABA canisters (vs. 0-2) was associated with increased exacerbation risk during follow-up (incidence rate ratios [95% confidence interval]: 1.35 [1.29-1.42], 1.22 [1.15-1.29], and 1.26 [1.19-1.34] for 0-5-, 6-11-, and 12-17-year-olds, respectively); the association persisted with SABA as a continuous variable and was stronger among patients without atopic diseases (32%-44% increased risk versus. 14%-21% for those with atopic disease across groups).ConclusionsHigh SABA use was associated with increased asthma exacerbation risk in children, particularly in those without comorbid atopic diseases, emphasizing the need for asthma medication reviews and reformative initiatives by caregivers and healthcare providers on SABA use.

Project description:BackgroundUS national guidelines recommend assessing short-acting beta-agonist (SABA) medication use as a marker of asthma severity and control. However, the relationship between recent SABA use and asthma exacerbations is not currently known.ObjectiveTo evaluate the proximal relationship between the type and frequency of SABA use and asthma-related outcomes.MethodsWe evaluated SABA use among patients with asthma ages 5 to 56 years who were members of a large health maintenance organization in southeast Michigan. Frequency of use was estimated from pharmacy data assessing the timing and amount of SABA fills. Cox proportional hazards models were used to examine the prospective relationship between average daily SABA use for 3 months and outcomes associated with poor asthma control (ie, oral corticosteroids use, asthma-related emergency department visits, and asthma-related hospitalizations). We separately accounted for SABA metered-dose inhaler (MDI) and SABA nebulizer use.ResultsOf the 2,056 patients who met study criteria, 1,569 (76.3%) had used a SABA medication in their baseline year. After adjusting for potential confounders, SABA nebulizer use was associated with asthma-related emergency department visits (adjusted hazard ratio [aHR], 6.32; 95% confidence interval [CI], 2.38 to 16.80) and asthma-related hospitalizations (aHR, 21.62; 95% CI, 3.17 to 147.57). In contrast, frequency of SABA MDI use was not associated with these outcomes.ConclusionsFrequency of SABA use during a 3-month period was associated with poor asthma outcomes. The relationship with poor asthma outcomes was strongest for SABA nebulizer use, suggesting that the type of SABA used is also of prognostic importance.

Project description:BACKGROUND Asthma is a common disease in the U.S. POPULATION:Initial therapy in the stepwise approach for asthma management is short-acting ??-agonist (SABA) therapy as needed for symptom control. However, a significant adverse event that can occur with administration is bronchospasm. Here, we report a case of paradoxical bronchospasm with administration of SABAs during multiple pulmonary function tests (PFTs). CASE REPORT A 25-year-old, non-smoking, African American male with a history of moderate asthma and allergic rhinitis treated with fluticasone/salmeterol diskus, albuterol hydrofluoroalkane (HFA) inhaler, and montelukast presented to our clinic complaining of recurrent episodes of acute shortness of breath immediately following each administration of albuterol for 4 weeks. PFTs were performed with levalbuterol (Xopenex) and albuterol (ProAir), yielding significant decrease in forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC). Nebulized albuterol and ipratropium bromide also improved FEV1 and FVC. He was successfully transitioned to an ipratropium rescue inhaler for asthma exacerbations. CONCLUSIONS Paradoxical bronchoconstriction is the unexpected constriction of smooth muscle walls of the bronchi that occurs in the setting of an expected bronchodilatory response. This phenomenon has been observed with ??-agonist-containing inhaler formulations and is an under-recognized adverse event. Theories suggest that the formulation excipients can trigger airway hyperresponsiveness in patients with allergically inflamed airways. Removal of excipients or use of anticholinergic inhalers improved respiratory function. Clinicians should be aware of paradoxical bronchospasm as an adverse effect with common inhaler formulations containing ??-agonists and counsel patients accordingly in the appropriate clinical setting.

Project description:IntroductionPreliminary results from the SABINA (SABA use IN Asthma) program showed lower overuse of short-acting β2-agonist (SABA) in Italy compared to other European countries. The aim of the present study was to ascertain whether SABINA's results might have been affected by the Italian National Health System and pharmaceutical market dynamics, by examining patients' characteristics in relation to SABA prescription/purchase habits.MethodsMultiple approaches were used: (1) a retrospective study using the General Practitioners' (GPs) Italian IQVIA Longitudinal Patient Database (LPD) to assess SABA overuse (more than two canisters/year) and its association with exacerbation risk; (2) a survey conducted across 200 Italian pharmacies to calculate the proportions of SABA purchases without a prescription; (3) a cross-sectional study on the specialists' IQVIA Patient Analyzer database to understand the SABA prescription habits of specialists.ResultsAmong SABA users identified through IQVIA LPD, the proportion of patients having more than two SABA canisters/year was 32%. Overall, patients prescribed more than two SABA canisters/year by GPs had 30% higher risk of exacerbations than patients with a maximum of two SABA canisters/year. The joint evaluation of IQVIA LPD and survey's findings revealed that IQVIA LPD tracks three out of four SABA canisters dispensed. The survey showed that, on average, SABA users purchased four canisters/year. Patients prescribed SABA by specialists were more frequently men, younger, thinner, and had higher spirometry values.ConclusionSABA overuse is common in Italy, with a share of consumption not regulated by medical prescriptions. Because SABA overuse increases exacerbation risk, changes to national guidelines should be encouraged to ensure implementation of global recommendations.

Project description:BackgroundOver-reliance on short-acting β2-agonists (SABAs) is associated with poor asthma outcomes. However, the extent of SABA use in Turkey is unclear owing to a lack of comprehensive healthcare databases. Here, we describe the demographics, disease characteristics and treatment patterns from the Turkish cohort of the SABA use IN Asthma (SABINA) III study.MethodsThis observational, cross-sectional study included patients aged ≥ 12 years with asthma from 24 centres across Turkey. Data on sociodemographics, disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by investigator-defined asthma severity (guided by the 2017 Global Initiative for Asthma [GINA]) and practice type (primary/specialist care). The primary objective was to describe SABA prescription patterns in the 12 months prior to the study visit.ResultsOverall, 579 patients were included (mean age [standard deviation; SD]: 47.4 [16.1] years; 74.3% female), all of whom were treated by specialists. Most patients had moderate-to-severe asthma (82.7%, GINA steps 3-5), were overweight or obese (70.5%), had high school or university/post-graduate education (51.8%) and reported fully reimbursed healthcare (97.1%). The mean (SD) asthma duration was 12.0 (9.9) years. Asthma was partly controlled/uncontrolled in 56.3% of patients, and 46.5% experienced ≥ 1 severe exacerbation in the preceding 12 months. Overall, 23.9% of patients were prescribed ≥ 3 SABA canisters in the previous 12 months (considered over-prescription); 42.9% received no SABA prescriptions. As few patients had mild asthma, only 5.7% were prescribed SABA monotherapy. Therefore, most patients (61.5%) were prescribed SABA in addition to maintenance therapy, with 42.8% receiving ≥ 3 SABA canisters in the previous 12 months. Inhaled corticosteroids (ICS), ICS + a long-acting β-agonist fixed-dose combination and oral corticosteroids were prescribed to 14.5%, 88.3% and 28.5% of all patients, respectively. Additionally, 10.2% of patients purchased SABA over the counter, of whom 27.1% purchased ≥ 3 canisters in the preceding 12 months.ConclusionsDespite all patients being treated by specialists and most receiving fully reimbursed healthcare, nearly a quarter of patients received prescriptions for ≥ 3 SABA canisters in the previous 12 months. This highlights a public health concern and emphasizes the need to align clinical practices with the latest evidence-based recommendations.

Project description:Significant indirect healthcare costs are related to uncontrolled asthma, including productivity loss. Days with short-acting beta-agonist (SABA) use is associated with symptom-related disruptions at work, home, and school. Digital self-management platforms may support fewer days with SABA medication use and may reduce symptom-related disruptions.

Project description:BackgroundOne goal of guideline-based asthma therapy is minimal use of short-acting β₂ agonist (SABA) medications. Inner-city children with asthma are known to have high SABA use.ObjectiveTo examine factors associated with high SABA use in inner-city children with asthma.MethodsOne 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.ResultsMean 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.ConclusionProviders should closely monitor SABA and controller medication use, allergen sensitization, and exposures in children with persistent asthma.Trial registrationClinicalTrials.gov, identifier NCT01981564.

Project description: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.

Project description:IntroductionComparative data on the efficacies of long-acting muscarinic antagonist (LAMA) and long-acting β2-agonist (LABA) combinations for the treatment of moderate-to-very-severe chronic obstructive pulmonary disease (COPD) are limited. The aim of this Bayesian network meta-analysis (NMA) is to assess the relative efficacies of available open combinations (delivered via separate inhalers) and fixed-dose combinations (FDCs, delivered via a single inhaler).MethodsWe conducted a systematic literature review with the aim of identifying randomized controlled trials (RCTs) of ≥8-week duration in adults aged ≥40 years with COPD that compared LAMA + LABA combinations with each other, with tiotropium (TIO), or with placebo. Data on changes from baseline in trough forced expiratory volume in 1 s (FEV1) and on St George's Respiratory Questionnaire (SGRQ) total score, the Transition Dyspnea Index (TDI) focal score, and rescue medication use at 12 and 24 weeks were extracted from these RCTs and analyzed using a NMA in a Bayesian framework.ResultsData from 44 RCTs were included in the NMA. All FDCs showed improvements relative to placebo in terms of trough FEV1, SGRQ total score, and TDI focal score above clinically relevant thresholds, with the exception of TIO/olodaterol and aclidinium/formoterol, both of which failed to show clinically relevant improvements in SGRQ score at 24 weeks. All FDCs demonstrated reduced rescue medication use versus placebo. Open combinations demonstrated improved efficacy in all outcomes versus placebo, but these improvements did not consistently exceed clinically relevant thresholds for SGRQ and TDI scores. All once-daily FDCs showed improved efficacy versus TIO, but improvements were less consistently observed versus TIO with open dual combinations and combinations containing formoterol or salmeterol administered twice daily. Relative probabilities of improvement between FDCs highlighted potential between-class differences for trough FEV1 but suggested little potential for differences in patient-reported outcomes.ConclusionLAMA + LABA combinations generally showed improved outcomes versus placebo and TIO. FDCs appeared to perform better than open dual combinations. A potential effectiveness gradient was observed between FDCs for objectively assessed functional outcomes, although further prospective trials are required to confirm these findings.FundingGSK.

Project description:Short-acting β2-agonist (SABA) use is known to be lower in Korean patients with asthma than in those from other countries, while the rate of asthma exacerbations in Korea is higher than in other countries. Thus, an epidemiologic study on SABA use and the relationship between SABA overuse and treatment outcomes in asthma is needed in Korea. We performed a cross-sectional study using the National Health Insurance Service-National Sample Cohort 2002-2012 database. We evaluated the trend of annual SABA use and overuse (prescription of 3 or more SABA canisters/year) and the impact of SABA overuse on mortality. During the study period, the proportion of asthmatic patients who used SABA was approximately 8%-11%, with no significant change in trend. The mean annual SABA use in asthmatic patients was 0.15-0.22 canisters/patient/year and 1.93-2.05 canisters/patient/year in those who used SABA in 12 months. SABA overuse was observed in about 2%-4% of asthmatic patients during the study period. SABA overuse generally tended to increase as the age of patients increased, with triple peaks in the late 20s (3.3%), late 40s (3.1%), and late 70s (3.6%). SABA overuse was associated with mortality (adjusted odds ratio, 1.72; 95% confidence interval, 1.61-1.84). The rate of SABA use was very low in Korean asthmatic patients between 2002-2012. SABA overuse was found in 2%-4% of patients in Korea. SABA overuse was associated with an increased risk of mortality.
