چکیده
Background: Predictors of medication adherence are not well known in chronic obstructive pulmonary disease (COPD). It is therefore necessary to identify factors associated with adherence to improve the effectiveness of COPD management within real-world situations. Objectives: The goals of this study were to estimate adherence to respiratory medication and to identify factors related to adherence in COPD patients. Methods: This was an observational, crosssectional study conducted on a sample of COPD outpatients. The following information was obtained: adherence to respiratory therapy (Morisky Medication Adherence Scale), age, gender, smoking status, COPD severity [Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage], lung function [post-bronchodilator forced expiratory volume in 1 s (FEV 1 )], treatment regimen for COPD, COPD medication costs per month paid by the patient and health-related quality of life (EuroQol 5-dimension questionnaire). A multivariate logistic regression analysis was performed to identify the independent predictors of adherence. Results: Of the 170 participants (mean age 63.8 years, 41.8% male), 58.2% reported optimal adherence. Adherence to respiratory therapy was Received: November 25, 2010 Accepted after revision: January 18, 2011 Published online: April 1, 2011 Tamas Agh University Pharmacy Department of Pharmacy Administration Semmelweis University, Hőgyes Endre Strasse 7–9 HU–1092 Budapest (Hungary) Tel. +36 1 216 1571, E-Mail aghtamas @ t-email.hu © 2011 S.

Evaluation of Prognostic Factors of Mortality in Patients with Chronic Obstructive Pulmonary Disease
Background and Objective: Chronic Obstructive Pulmonary Disease (COPD) is a chronic obstructive and irreversible disease which has a high mortality and morbidity rate. Systemic inflammation and the thrombotic process can influence the prognosis of these patients. The objectives of this study were to evaluate prognostic effects of CBC indices (WBC, PMN, MPV, RDW), forced expiratory volume-one se...
متن کاملHomocystein Level and Total Antioxidant Capacity in Chronic Obstructive Pulmonary Disease
Abstract Background and Objective: Oxidant-antioxidant imbalance plays a key role in pathogenesis of chronic obstructive pulmonary disease (COPD). This study aimed to evaluate homocystiene and total antioxidant capacity in COPD patients, compared to smoker and non-smoker healthy people.

متن کاملSerum and Saliva Theophylline Levels in Adult Outpatients with Asthma and Chronic Obstructive Pulmonary Disease (COPD): A Cross-Sectional Study
Due to a narrow therapeutic range, measurment of theophylline serum levels is highly recommended in patients with a long-term theophylline therapy. In this regard, since blood sampling is an invasive method, exploring alternative methods using other biological fluids in particular saliva samples are targeted. This study was designed to determine any relationship between serum and saliva levels ...

متن کاملThe Relationship between Diaphragmatic Movements in Sonographic Assessment and Disease Severity in Patients with Stable Chronic Obstructive Pulmonary Disease (COPD)
Introduction: Pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (COPD) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. The purpose of this study was to compare diaphragmatic movements in COPD patients and healthy ones and to evaluate ...
