Summary
ASTHMAXcelED, a mobile health app, improved asthma control and quality of life in patients discharged from the emergency department. This user-centric mHealth tool shows promise for better patient outcomes and reduced healthcare utilization.
Area of Science:
- Digital Health
- Patient Outcomes
- Asthma Management
Background:
- Mobile health (mHealth) applications can enhance patient outcomes, but few are clinically tested with user-centric design.
- ASTHMAXcelED is a patient-facing mobile application specifically designed for emergency department (ED) asthma patients.
Purpose of the Study:
- To evaluate user acceptance of the ASTHMAXcelED application.
- To compare asthma control and quality of life measures before and after ASTHMAXcelED use.
Main Methods:
- A prospective cohort study in two urban EDs involving 149 adult asthma exacerbation patients.
- Participants downloaded ASTHMAXcelED upon discharge; asthma control (Asthma Control Test) and user acceptance were measured.
- Follow-up assessments were conducted to evaluate changes in asthma control and app usage intention.
Main Results:
- Good asthma control (ACT > 19) improved from 27% at baseline to 54% at 4-week follow-up (p < 0.01).
- Low rates of ED revisit (7%) and zero asthma hospitalizations were observed during the study period.
- 39% of patients intended to continue using ASTHMAXcelED post-study.
Conclusions:
- ASTHMAXcelED use for 4 weeks improved asthma symptom control and quality of life.
- The application demonstrated potential as an easily adopted mHealth education platform.
- Findings suggest ASTHMAXcelED can positively impact patient outcomes and potentially reduce healthcare resource utilization.

01:29Asthma-I: Introduction
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
01:28Asthma I: Introduction
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
01:13Asthma III: Clinical Manifestations
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
01:30Asthma-IV: Nursing Management
The nursing management of asthma is a comprehensive approach that relies heavily on the expertise and dedication of healthcare professionals. It involves thorough assessment, accurate diagnosis, strategic planning, effective implementation, and diligent evaluation. By meticulously following this step-by-step process, healthcare professionals play a crucial role in providing the best possible care and treatment for patients with asthma, enhancing their overall health and well-being.

01:20Asthma: Pathogenesis and Management
Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
