Filter by:The aim of this study is to compare the clinical effectiveness and cost-effectiveness of the Easyhaler® (EH) device and other DPI devices commonly used in the UK in a UK primary care asthma population of patients aged 6 to 80 years.
Asthma is a common disease that affects people of all ages and has significant morbidity and mortality. Poor outcomes and health disparities related to asthma result in part from the difficulty of disseminating new evidence and paradigms of care delivery such as shared decision making (SDM) into clinical practice. This study will evaluate a novel mechanism for dissemination of an evidence-based SDM Toolkit for asthma care in primary care practices. The study is ideally suited to study dissemination methods because it will leverage a partnership between an established consortium of practice based research networks (PBRNs) and an advanced Medicaid Network. This study will evaluate a novel dissemination process (FLOW) to spread an Asthma Shared Decision Making Toolkit to practices within a Medicaid network using a consortium of practice-based research networks (NCNC). The knowledge gained from this proposal and the partnerships formed between practice-based research networks and NC Medicaid will facilitate widespread dissemination to almost 300 practices.
The aim of the study is to compare the effect of asthma care by clinical pharmacist intervention versus routine care on asthma control.
The VENTOLIN Mini-Spacer is being developed in order to support patients in the Emerging Markets and Asia Pacific regions who do not have access to affordable spacers. The aim of this exploratory study is to investigate whether the systemic exposure for fluticasone propionate (FP) and salmeterol observed with the VENTOLIN Mini-Spacer is comparable to the systemic exposure for FP and salmeterol observed with the Trudell Aerochamber Plus spacer for both FLIXOTIDE and SERETIDE Metered Dose Inhaler (MDI) products. There will be four study periods in the study and all participants will receive four study treatments during the study. The total duration of study including screening, treatment period, washout period, and follow-up period will be 58 days. Study is planned to enroll 20 healthy subjects.

40 subjects with moderate-to-severe asthma will be randomly selected for study in which 20, will be monitored for medication use (Dulera 100/5, Dulera 200/5 and Proventil HFA) over 3 months. These intervention subjects will receive medication use feedback at each visit, while the control group will receive the standard of asthma care. Those interventional subjects with Dulera adherence<60% will receive feedback based on an asthma adherence disease management model protocol, Asthma Adherence Pathway. Intervention clinicians will been trained in Motivational Interviewing to reduce subject ambivalence about medication use. The primary hypothesis is that subjects who receive medication monitoring and Motivational Interviewing adherence strategies will have better asthma control, as measured by the Asthma Control Questionnaire, than the control group.
The research goal is to explore the use and effects of a custom-recordable audio discharge instruction card (Talking Card) in the pediatric health care setting. This study will address a primary, experimental research question: can pediatric asthma control be improved through the distribution of a custom-recorded audio asthma instruction card to parents at the health provider's office? Secondary, descriptive objectives will be to evaluate feasibility of Talking Card delivery and to collect and summarize parental reactions to the design and use of the audio discharge instruction card. The specific aims of this study are: 1. To compare the change in mean Childhood Asthma Control Test (C-ACT) scores for children aged 4 through 11 years with uncontrolled asthma receiving a custom-recorded asthma instruction card to the change in mean C-ACT scores for those receiving usual care. 2. To measure the use and impressions of a custom-recordable audio asthma discharge instruction card among primary caregivers of children with uncontrolled asthma through quantitative and qualitative survey questions. The investigators hypothesize that: 1) Asthma control in children 4 through 11 years of age with uncontrolled asthma, as measured by the C-ACT, will improve to a greater extent among those receiving a custom-recordable audio discharge instruction card than among those receiving usual care.
This is a randomized, double-blind, placebo-controlled parallel-group study. Participants will be randomly assigned to receive treatment with beclomethasone dipropionate at a dosage of 80 or 160 mcg/day delivered via a Breath-Actuated Inhaler (BAI); or a matching BAI placebo, in a 1:1:1 ratio after a 14- to 21-day run-in period. Participants and investigators will remain blinded to randomized treatment assignment during the study
This randomized, double-blind, double-dummy, placebo-controlled, parallel-group, 12-week study will evaluate the efficacy and safety of beclomethasone dipropionate (80 or 160 mcg/day) administered via breath-actuated inhaler (BAI) and metered-dose inhaler (MDI) in pediatric patients 4 through 11 years of age with persistent asthma, compared with placebo. Patients took 1 inhalation (with assistance from parents/guardians/caregivers, as needed) from each of 2 devices (BAI device followed by MDI device in that order) twice daily as per the double-dummy study design: 1 BAI treatment or placebo device and 1 MDI treatment or placebo device for a total of 2 inhalations each time.
Studies examining the sex differences in the epidemiology and morbidity patterns of asthma show that the rates of disease severity, healthcare utilisation, and poor quality of life are considerably higher in women than in men, and this has been attributed to endogenous and exogenous sex hormonal factors. Studies examining the impact of use of hormonal contraceptives on the risk of asthma and asthma-related conditions are few, yet findings are conflicting. In the present study, the investigators utilize data from the Scottish Health Survey, a national representative sample, to investigate the associations between current use of hormonal contraceptives and the prevalence of self-reported doctor-diagnosed current asthma and wheezing symptoms in Scottish women. The investigators hypothesize that while current use of any hormonal contraceptives and combined oral pills are associated with higher prevalence of asthma and asthma outcomes, current use of progesterone-only contraceptives is not associated with asthma. A secondary aim of the current study is to examine whether there is evidence of any biological interaction between use of hormonal contraceptives and BMI in relation to the risk of asthma and asthma outcomes.
Asthma is a common condition which produces a significant workload for general practice, hospital outpatient clinics and inpatient admissions. Asthma is caused by inflammation of the airways which irritates the muscles around the airways causing them to constrict. The mainstay of asthma treatment is inhaled steroids. If the patients' symptoms are still not adequately controlled, then a long-acting beta agonist (LABA) inhaler which relaxes the muscles in the airways and opens it up is frequently added to the inhaled steroids. Despite this, a substantial proportion of asthmatic patients still do not achieve adequate control of their symptoms. Recent studies have shown when an alternative inhaler called a long-acting muscarinic antagonist (LAMA) is added to a LABA - it reduced the number of asthma exacerbations (flare-ups) and improved airway narrowing. The mannitol challenge is a test of airway 'twitchiness', an important feature of asthma. There have been no previous studies assessing the combined effects LABA and LAMA inhalers on mannitol challenge. The mannitol challenge is particularly relevant as it mimics stimuli encountered in real life which provoke an asthma attack. The investigators propose to directly compare indacaterol, a new once-daily LABA with indacaterol plus tiotropium, a once-daily LAMA, as add-on treatment to inhaled steroids in persistent asthmatics using the mannitol challenge. The investigators hope that this study will help us understand how the combination of a LABA and LAMA might help protect against flare-ups.
