This cross-sectional survey study is intended to describe the characteristics of adults in 4 US states with regards to respiratory symptoms and tobacco exposure, utilizing an existing state-administered, CDC overseen Behavioral Risk Factor Surveillance System telephone health survey. The primary goal of study is to describe the sociodemographics, health behaviors, and presence of chronic diseases in persons with or at risk of having chronic obstructive pulmonary disease.
Asthma exacerbations account for a significant morbidity and disproportionate health care costs. However, there is no currently available biomarker or lung function parameter that can accurately predict the risk of future exacerbations. The current work aims at evaluating the resting ventilatory flow by applying a new technique called anharmonic morphological analysis of the respiratory signals (AMARS). We hypothesize that monitoring AMARS is potentially able to detect an increased risk of asthma exacerbations.
The introduction of inhaled medication as the primary treatment for asthma has led to substantial improvements in asthma control [1, 2]. However, uncontrolled asthma is still common and represents a considerable burden to patients and society [3, 4]. An important reason for poor asthma control and consequently, increased healthcare expenditure is suboptimal adherence to the prescribed regimen [5-7]. Real-world market research study in hospitals across China reported that physicians perceived that only 23% of patients were fully compliant with their medication regime (77% non-adherent), compared to 55% in the European Union and 63% in the US [AZ internal document]. The physician reported rate of full adherence was lower than the patient-reported rate (38%). Poor patient adherence was the challenge most frequently mentioned (by 41% of physicians) when treating an asthma.[8] However There is some evidence on the drivers of patient behaviour around low adherence but more depth research is needed There is little evidence on variation of determinants of asthma inhaled treatment across different age of group Our research aims to address above data gap Mean while this research can guide the development of new module on Red Scarf patient education program.
Background: Asthma and COPD are considered different diseases but many patients share characteristics of both entities. This has been termed "COPD-asthma overlap syndrome". Study objective: To examine: (a) the frequency of the overlap phenotype among patients referred for pulmonary function testing and, (b) the impact of this phenotype on the therapeutic management and the quality of life of these patients as compared with patients with COPD only and asthma only. Methods: Type of study: Observational, cross-sectional. Study subjects: Patients referred for pulmonary function test diagnosed with airway obstruction (FEV1/FVC < 0.7) willing to sign an informed consent. Study procedures: Spirometry will be performed before and after the administration of a bronchodilator. Respiratory questionnaire: Questionnaires about smoking habits, past history of asthma and wheezing, current medications and history of exacerbations will be administered at inclusion. Questionnaire on medication utilization will be administered by telephone one month after inclusion. Quality of life: Will be assessed using the Saint George Respiratory Questionnaire (SGRQ). Working definitions: The following definitions will be adopted: a) COPD only: smoking history > 10 pack/years and post-bronchodilator (BD) FEV1/FVC ratio of < 0.70; b) Asthma only: (1) presence of wheezing in the last year plus a minimum post-BD increase in FEV1 or FVC of 12% and 200 ml; (2) prior physician diagnosis (before age 40); and c) both COPD-Asthma (the overlap group) - the combination of the two. Outcome measures: The clinical outcome is the prevalence rate of the phenotypes. Patient-reported outcomes will include the utilization of medication, the number of exacerbations, and quality of life.
The aim of the study is to evaluate the errors that may occur during inhalation of two devices in patients with asthma, as well as to study whether it relates to the degree of control of patient symptoms and the degree of compliance of medication symptoms. Finally, we also want to study the degree of patient satisfaction with each of the inhalers studied
This study is to evaluate the safety and efficacy of fluticasone propionate and fluticasone propionate salmeterol in pediatric participants with a documented history of persistent asthma.
This study will use inhaler technology to observe and feedback overall patterns of medication use. We will look at whether this improves preventer inhaler use and reduces reliever inhaler overuse. We will also assess whether inhaler technology is patient-friendly and cost effective, whether it helps with treatment decisions in asthma and whether it can help us to predict and prevent asthma attacks.
The purpose of this study is to investigate the lung deposition and distribution pattern of Beclometasone dipropionate/Formoterol Fumarate/Glycopyrronium Bromide using a Gamma-scintigraphic technique after inhalation of a single dose of 99mTc radiolabelled CHF 5993 Administered via pMDI in healthy volunteers, asthmatic and COPD patients.
This study evaluates the longterm clinical outcomes, including safety and efficacy parameters after Bronchial Thermoplasty (BT) treatment over a period of 5 years. All patients included in de TASMA trial in the Netherlands will be asked to participate in the TASMA extension study.
