Quality of life of patients with chronic obstructive pulmonary disease in the gulf cooperation council countries

ABSTRACT

To assess the health-related quality of life [HRQL] of patients with chronic obstructive pulmonary disease [COPD] in 4 Gulf Council Cooperation countries. We conducted a cross-sectional survey between December 2011 and March 2012 in the following countries Kingdom of Saudi Arabia [Riyadh, Dammam, and Jeddah], Kuwait, Bahrain, and the United Arab Emirates. The HRQL was measured using the COPD Assessment Test [CAT] and the Chronic Respiratory Disease Questionnaire-Self-Administered Standardized questionnaire [CRQ-SAS]. We recruited 120 patients from 6 centers in 4 countries. Their average forced expiratory volume [FEV][1] was 49.3% [+/- 13.4] of predicted, and the ratio of FEV[1] to forced vital capacity was 0.58 [+/- 0.11]. The average COPD Assessment Test [CAT] score was 20.4 +/- 7.6; CAT scores were highest for Riyadh [24.1 +/- 7.7]; and lowest for Kuwait [18.5 +/- 9.2], with no significant difference between the centers. For the CRQ-SAS, the dyspnea domain score was 4.6 +/- 1.6, the fatigue domain score was 4.3 +/- 1.3, the emotional domain was 4.6 +/- 1.2, and the mastery domain was 4.8 +/- 1.4. The correlation coefficients of the association between the CAT score and the 4 domains of the CRQ-SAS for all of the centers combined was statistically significant. The CAT and CRQ-SAS revealed that the patients with COPD experienced a moderate to severe impact from the disease, and a considerably compromised quality of life in the GCC countries
