TLDR
Results reinforce the usefulness of a brief, easy to administer, patient-based index of asthma control.Abstract:
Background Asthma guidelines indicate that the goal of treatment should be optimum asthma control In a busy clinic practice with limited time and resources, there is need for a simple method for assessing asthma control with or without lung function testing Objectives The objective of this article was to describe the development of the Asthma Control Test (ACT), a patient-based tool for identifying patients with poorly controlled asthma Methods A 22-item survey was administered to 471 patients with asthma in the offices of asthma specialists The specialist's rating of asthma control after spirometry was also collected Stepwise regression methods were used to select a subset of items that showed the greatest discriminant validity in relation to the specialist's rating of asthma control Internal consistency reliability was computed, and discriminant validity tests were conducted for ACT scale scores The performance of ACT was investigated by using logistic regression methods and receiver operating characteristic analyses Results Five items were selected from regression analyses The internal consistency reliability of the 5-item ACT scale was 084 ACT scale scores discriminated between groups of patients differing in the specialist's rating of asthma control (F = 345, P P 1 (F = 43, P = 0052) As a screening tool, the overall agreement between ACT and the specialist's rating ranged from 71% to 78% depending on the cut points used, and the area under the receiver operating characteristic curve was 077 Conclusion Results reinforce the usefulness of a brief, easy to administer, patient-based index of asthma controlread more

Stepping-across controlled asthmatic patients to extrafine beclometasone/formoterol combination
Neil Barnes,Jan Arie van Noord,Caterina Brindicci,Ludger Lindemann,Guido Varoli,Miguel Perpiña,Daniele Guastalla,Daniela Casula,Shishir Patel,Pascal Chanez +9 more
TL;DR: Patients previously controlled with FP/S in any device formulation can effectively step-across to extrafine BDP/F pMDI, maintaining lung function and asthma control with a 5-min onset of action.

Latent Class Analysis of School-Age Children at Risk for Asthma Exacerbation
TL;DR: Outcomes were driven largely by children with exacerbation prone asthma, who were present in each class but most strongly represented in classes 3 and 4, and time to exacerbation followed similar trends.

Improving asthma care for African American children by increasing national asthma guideline adherence.
TL;DR: The primary aim of this study was to increase health care provider adherence to the NAEPP guidelines by means of a guideline reminder tool, the Multi-colored Simplified Asthma Guideline Reminder, consequently increasing the prescription of ICS in this population of children.

TL;DR: There were significant correlations between the results from the Asthma Control Test and the Sino-Nasal Outcome Test-22 and between the ACT and Rhinoconjunctivitis Quality of Life Questionnaire and nasal surgery improved the sinonasal symptoms, asthma control, and pulmonary function.

The meaning and use of the area under a receiver operating characteristic (ROC) curve.
TL;DR: A representation and interpretation of the area under a receiver operating characteristic (ROC) curve obtained by the "rating" method, or by mathematical predictions based on patient characteristics, is presented and it is shown that in such a setting the area represents the probability that a randomly chosen diseased subject is (correctly) rated or ranked with greater suspicion than a random chosen non-diseased subject.

A method of comparing the areas under receiver operating characteristic curves derived from the same cases.
TL;DR: This paper refines the statistical comparison of the areas under two ROC curves derived from the same set of patients by taking into account the correlation between the areas that is induced by the paired nature of the data.

Ira B. Wilson,Paul D. Cleary +1 more
TL;DR: This model proposes a taxonomy or classification scheme for different measures of health outcome, dividing these outcomes into five levels: biological and physiological factors, symptoms, functioning, general health perceptions, and overall quality of life.

TL;DR: In this paper, the authors present national data regarding self-reported asthma prevalence, school and work days lost because of asthma, and asthma-associated activity limitations (1980-1996); asthmaassociated outpatient visits, asthmaassociated hospitalizations, asthma associated hospitalizations and asthmaassociated deaths.
