Adherence of North-African Pulmonologists to the 2017-Global Initiative for Chronic Obstructive Lung Disease (GOLD) Pharmacological Treatment Guidelines (PTGs) of Stable Chronic Obstructive Pulmonary Disease (COPD)

Abstract

Background. No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs. Aims. To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence. Methods. This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation. The patients were classified as having been appropriately and inappropriately (over- or undertreatment) treated for the GOLD group. Logistic regression was performed to determine the adherence barriers to the 2017-GOLD PTGs. Results. A total of 296 patients were included (88.1% males, mean age: 68±10 years; GOLD A (7.1%), B (36.1%), C (4.1%), and D (52.7%)). The pulmonologists’ adherence rate to the 2017-GOLD PTGs was 29.7%. There was a significant statistical difference between the adherence rates among the four GOLD groups (A: 19.0%, B: 20.6%, C: 8.3%, and D: 39.1%; p=0.001). Differences were statistically significant between the GOLD group D and groups B (p=0.001) and C (p=0.033). The multivariate analysis showed that age (odds ratio (OR): 0.968), socioeconomic level (high/medium vs. low; OR: 2.950), insurance type (national health insurance vs. others; OR: 2.851), and GOLD groups (A/B vs. C/D; OR: 3.009) significantly influenced the adherence rate to the 2017-GOLD PTGs. Conclusion. The adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs is low. It seems that the patients’ age, socioeconomic level, national health insurance coverage, and GOLD groups influenced their adherence.
