Asthma insights from Jordan: cross-sectional observational study

Abstract

Objective: The burden of uncontrolled asthma on patients in Jordan is largely unknown. This study assessed different aspects of asthma clinical features: the level of asthma control, its correlation with quality of life, and possible predictors of asthma control.

Methods: Face-to-face interviews with asthmatic patients (≥16 years old) in north Jordan from 2013 to 2014 were conducted. Outcomes measures were assessed using the asthma control test (ACT), the mini asthma quality of life questionnaire (mini-AQLQ), and the Generic health-related quality of life (EQ-5D). The relationship between asthma control and quality of life was examined using Spearman's correlation coefficient. Predictors of asthma control were determined using multivariable logistic regression adjusted for confounders.

Results: A total of 255 patients were recruited (mean age 45.16 years, 74.5% female). Approximately one-third of subjects (30.6%; n = 78) had controlled asthma (ACT ≥ 20). A strong correlation between asthma control and both mini-AQLQ and EQ-5D scores was identified (p < 0.001). Subjects who required to step-up treatment (OR = 0.12, 95% CI: 0.02-0.63, p = 0.01) and with acute asthma exacerbation (OR = 0.32, 95% CI: 0.18-0.58, p < 0.001) were independently associated with poor asthma control.

Conclusions: Most of the recruited patients have not achieved optimal asthma control and was associated with low quality of life. The study highlights that even in low-income countries, a simple assessment tool such as the ACT can be utilized to screen and categorize asthma control. This approach would facilitate a better treatment plan and eventually improve asthma control and quality of life in asthma patients.
