Background: Asthma in children is a leading cause of missed school days, emergency department visits, and hospitalizations. Approximately 40% of children with asthma experience uncontrolled disease and annual exacerbations. There is a need for a validated composite tool for children, such as the Asthma Impairment and Risk Questionnaire (AIRQ), which was developed to assess current control and predict exacerbations in adolescents and adults with asthma.

Objectives: The purpose of this study was to assess whether sodium zirconium cyclosilicate (SZC), a nonabsorbed crystal that traps and rapidly lowers potassium, enables MRA use in patients with HFrEF and prevalent hyperkalemia (or at high risk).
Background: Patient perception of medication onset of effect is important for adherence. Although the Onset of Effect Questionnaire (OEQ) has been validated in patients with asthma, it has not been evaluated in patients with chronic obstructive pulmonary disease (COPD). This study evaluated the COPD-OEQ in patients with COPD.
View Article and Find Full Text PDFBackground: Complex models combining impairment-based control assessments with clinical characteristics and biomarkers have been developed to predict asthma exacerbations. The composite Asthma Impairment and Risk Questionnaire (AIRQ) with adjustments for demographics (age, sex, race, and body mass index) predicts 12-month exacerbation occurrence similarly to these more complex models.
Objective: To examine whether AIRQ exacerbation prediction is enhanced when models are adjusted for a wider range of clinical characteristics and biomarkers.
Key Points: Sodium zirconium cyclosilicate effectively lowers serum potassium and maintains normokalemia in patients with CKD with concomitant hyperkalemia and metabolic acidosis. Despite high screen failure and small sample size, a nominally significant increase in sHCO was seen for sodium zirconium cyclosilicate versus placebo. Further studies on the basis of an appropriate cohort size may help validate the trend observed in sHCO levels, supporting these clinically relevant findings.

Objective: To analyze the performance of the composite Asthma Impairment and Risk Questionnaire (AIRQ) in assessing both domains of control and predicting exacerbation risk compared with the Global Initiative for Asthma (GINA) 4-question symptom control tool (GINA SCT), Asthma Control Test (ACT), and physician expert opinion (EO) informed by GINA SCT responses and appraisal of GINA-identified risk factors for poor asthma outcomes.
Methods: Multivariable logistic regressions evaluated AIRQ and GINA SCT as predictors of ACT.

Background: The Asthma Impairment and Risk Questionnaire (AIRQ) is a 10-item, yes/no, equally weighted control tool. Lower scores indicate better control. Moreover, 7 impairment items reflect previous 2-week symptoms, and 3 risk items assess previous 12-month exacerbations.

We present the rationale and design of CONTINUITY, a study to examine the efficacy of continuing sodium zirconium cyclosilicate (SZC)-an oral, highly selective potassium (K) binder-compared with standard of care (SoC) on maintaining normokalemia and reducing re-hospitalization and resource utilization among participants with CKD hospitalized with hyperkalemia.
Methods: This Phase 4, randomized, open-label, multicenter study will enroll adults with Stage 3b-5 CKD and/or estimated glomerular filtration rate <45 mL/min/1.

Background: Asthma control is often overestimated in routine practice, and despite advances in the understanding of immunopathology and the availability of new precision therapies, the burden of disease remains unacceptably high.
Objective: To compare the performance of the Asthma Impairment and Risk Questionnaire (AIRQ) with patient and physician assessments and the Asthma Control Test (ACT) in identifying asthma control.
Methods: Baseline data from a longitudinal study of the AIRQ were analyzed.
Purpose: Critical asthma outcomes highlighted in clinical guidelines include asthma-related quality of life, asthma exacerbations, and asthma control. An easy-to-implement measure of asthma control that assesses both symptom impairment and exacerbation risk and reflects the impact of asthma on patients' lives is lacking. Hence, the objective of this study was to assess the Asthma Impairment and Risk Questionnaire (AIRQ) construct validity relative to patient self-perception of asthma status and validated disease-specific patient-reported outcome (PRO) measures.
View Article and Find Full Text PDFBackground: The Asthma Impairment and Risk Questionnaire (AIRQ) is a 10-item, equally weighted, yes/no control tool validated in patients with asthma aged 12 years and older.
Objective: To evaluate AIRQ's ability to predict patient-reported exacerbations over 12 months.
Methods: Patients completed a baseline AIRQ during an in-person enrollment visit and reported exacerbations (ie, asthma-related courses of oral corticosteroids, emergency department/urgent care visits, and hospitalizations) via monthly online surveys.
Background: Recurrent assessment of asthma control is essential to evaluating disease stability and intervention impacts. An assessment that can be administered between annual clinic visits is needed. The Asthma Impairment and Risk Questionnaire (AIRQ) is a cross-sectionally validated, 10-item, yes or no, composite control tool evaluating previous 2-week symptoms and previous 12-month exacerbations.

This study evaluated real-world adoption of the chronic obstructive pulmonary disease (COPD) Co-Pilot daily symptom monitoring tool by patients and primary care providers (PCPs).
Methods: An open-label, 6-month, single-arm, multicenter, noninterventional feasibility study enrolled 97 patients aged ≥ 40 years with symptomatic or poorly controlled COPD and ≥ 10 pack-year smoking history.
Background: A variety of dual-combination maintenance inhalers are used to treat asthma and chronic obstructive pulmonary disease (COPD). Understanding patient preferences for treatment attributes may help select an optimal treatment from the patient perspective.
Methods: Patient preferences for maintenance inhaler device and medication attributes were elicited through a discrete choice experiment and used in benefit-risk assessments to calculate predicted choice probabilities (PrCPs) for 14 dual-combination maintenance inhalers in four treatment classes: lower- and higher-dose inhaled corticosteroid (ICS)/long-acting beta agonist (LABA) inhalers for asthma, and ICS/LABA and long-acting muscarinic antagonist (LAMA)/LABA inhalers for COPD.
Background: Cost is frequently cited as a barrier to optimal medication use, but the extent to which copayment assistance interventions are used when available, and their impact on evidence-based medication persistence and major adverse cardiovascular events is unknown.
Methods And Results: The ARTEMIS trial (Affordability and Real-World Antiplatelet Treatment Effectiveness After Myocardial Infarction Study) randomized 301 hospitals to usual care versus the ability to provide patients with vouchers that offset copayment costs when filling P2Y inhibitors in the 1 year post-myocardial infarction. In the intervention group, we used multivariable logistic regression to identify patient and medication cost characteristics associated with voucher use.
Background: Asthma exacerbation risk increases with worsening asthma control. Prevailing numerical control tools evaluate only current symptom impairment despite the importance of also assessing risk based on exacerbation history. An easy-to-use questionnaire addressing impairment and risk domains of control is needed.

Background Hospitals commonly provide a short-term supply of free P2Y inhibitors at discharge after myocardial infarction, but it is unclear if these programs improve medication persistence and outcomes. The ARTEMIS (Affordability and Real-World Antiplatelet Treatment Effectiveness After Myocardial Infarction Study) trial randomized hospitals to usual care versus waived P2Y inhibitor copayment costs for 1-year post-myocardial infarction. Whether the impact of this intervention differed between hospitals with and without pre-existing medication assistance programs is unknown.

Study Design: This was a retrospective, repeated cross-sectional, cohort study.
Methods: Adult patients with T2D with more than 1 prescription for a GLP-1 RA in the Optum Humedica database between December 2014 and March 2016 were included.
Objectives: Cardiovascular outcomes trials (CVOTs) for evaluating the safety of novel antidiabetic agents are required by the FDA. CVOTs vary in their design and inclusion criteria, making it difficult to evaluate their applicability to the general population. This study examined the proportion of adults eligible for 7 ongoing or completed glucagon-like peptide-1 receptor agonist (GLP-1 RA) CVOTs.
