Aims: To investigate the association of the GOLD ABCD groups classification with costs and health-related quality of life (HR-QoL) and to compare this with the GOLD 1234 grades classification that was primarily based on lung function only. Methods: In a cross-sectional study, we selected patients diagnosed with chronic obstructive pulmonary disease (COPD) from electronic medical records of general practices. Multi-level analysis was used with costs (medication, primary care, healthcare, societal), diseasespecific and generic HR-QoL as independent variables. Either the new or the old GOLD stages were included in the analysis together with several covariates (age, gender, living situation, co-morbidity, self-efficacy, smoking, education, employment). Results: 611 patients from 28 general practices were categorised as GOLD-A (n=333), GOLD-B (n=110), GOLD-C (n=80) and GOLD-D (n=88). Patients in the GOLD-B and GOLD-D groups had the highest prevalence of co-morbidities and the lowest level of physical activity, self-efficacy, and employment. The models with GOLD ABCD groups were more strongly related to and explained more variance in costs and in disease-specific and generic HR-QoL than the models with GOLD 1234 grades. The mean Clinical COPD Questionnaire score worsened significantly, with scores 1.04 (GOLD-B), 0.4 (GOLD-C) and 1.21 (GOLD-D) worse than for patients in GOLD-A. Healthcare costs per patient were significantly higher in GOLD-B (72%), GOLD-C (74%) and GOLD-D (131%) patients than in GOLD-A patients. Conclusions: The GOLD ABCD groups classification is more closely associated with costs and HR-QoL than the GOLD 1234 grades classification. Furthermore, patients with GOLD-C had a better HR-QoL than those with GOLD-B but the costs of the two groups did not differ. © 2014 Primary Care Respiratory Society UK. All rights reserved.
