Summary
High adherence to inhaled therapy was observed in 38.7% of patients with Chronic Obstructive Pulmonary Disease (COPD) and asthma. Patients with COPD and basic education levels demonstrated better adherence, with unwitting non-compliance being most common.
Area of Science:
- Pulmonology
- Respiratory Medicine
- Patient Adherence Research
Background:
- Inhaled therapies are crucial for managing Chronic Obstructive Pulmonary Disease (COPD) and asthma.
- Patient adherence to these therapies significantly impacts treatment outcomes.
- Understanding adherence levels and influencing factors is essential for optimizing respiratory care.
Purpose of the Study:
- To determine the adherence rate to inhaled therapy in patients with COPD and asthma.
- To identify the types of non-compliance and factors influencing adherence in a pulmonology clinic setting.
Main Methods:
- A descriptive, cross-sectional study was conducted.
- 124 patients (62 female, 62 male, average age 63) with COPD or asthma were enrolled.
- Adherence was measured using the 'Test of Adherence to Inhalers' (TAI) questionnaire.
Main Results:
- 38.7% of patients exhibited high adherence, 37.9% intermediate, and 23.4% low adherence.
- Unwitting non-compliance (28.2%) was the most frequent type, followed by erratic (13.7%) and deliberate (4.8%).
- Patients with COPD (51.6%) showed higher adherence than asthmatics (48.4%) (P=.02). Higher adherence was also noted in patients with basic education (P=.05).
Conclusions:
- Nearly 40% of patients demonstrated high adherence to inhaled therapies, with unwitting non-compliance being prevalent.
- COPD patients and those with a basic education level exhibited superior adherence.
- While training by healthcare professionals appeared beneficial, significant statistical differences were not detected, suggesting further investigation into effective adherence strategies is warranted.

800
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

01:24Pulmonary Ventilation: Inhalation
8.1K
Pulmonary ventilation is a vital process that ensures the exchange of oxygen and carbon dioxide in the lungs. It refers to the movement of air into and out of the lungs, enabling the body to obtain oxygen and remove waste carbon dioxide. In this article, we will explore the intricacies of pulmonary ventilation, including its underlying principles, mechanisms, and the interplay of pressures within the respiratory system.

01:20Inhalational Anesthetics: Overview
1.1K
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

00:59Gene Therapy
27.6K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

01:12Setting Time of Cement
677
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

01:25Antiasthma Drugs: Inhaled Corticosteroids and Glucocorticoids
1.6K
Inhaled corticosteroids (ICS) are anti-inflammatory drugs used primarily in treating persistent asthma and providing long-term maintenance. They target the bronchial mucosa, the lining of the airways, to control inflammation, a critical factor in asthma progression and exacerbation.
ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...
