National Epidemiological Case-Control Study of Pharmacological Smoking Cessation Treatment in Danish Patients with Chronic Obstructive Pulmonary Disease

Pharmacological smoking cessation of adults aged 30-50 years with COPD

The prevalence of active smokers has remained relatively stable around 20% for several years in Denmark despite knowledge of the harmful effects. Smoking cessation is the most effective way to limit progression and reduce mortality of chronic obstructive pulmonary disease (COPD). Therefore, smoking cessation is particularly important among adults with COPD. The aim of this study was to determine the extent to which adults 30–50 years of age with COPD redeem pharmacotherapy for smoking cessation, and to identify demographic factors that influence the use of smoking cessation medication. We conducted a national retrospective non-interventional registry study, including all Danish patients with COPD (ICD-10 code J.44: chronic obstructive pulmonary disease) aged 30–50 years in the period 2009–2015. We identified 7734 cases, who were matched with controls (15,307) 1:2 on age, sex, and geography. Smoking status was not registered. We found that 18% of cases (with an estimated smoking prevalence at 33–50%) redeemed pharmacological smoking cessation medication in the study period compared to 3% of the controls (with an estimated smoking prevalence at 23%). The OR for cases collecting pharmacological smoking cessation medication was 5.92 [95% CI 5.24–6.70]. Male sex, being unemployed, and receiving social benefits were factors associated with less probability of redeeming pharmacological smoking cessation medication. Our study indicates that attention is needed on smoking cessation in adults aged 30–50 years with COPD, especially if unemployed or receiving social benefits, as these individuals are less likely to redeem pharmacological smoking cessation medication.

Vaccination and modern management of chronic obstructive pulmonary disease - a narrative review

INTRODUCTION

Chronic obstructive pulmonary disease (COPD) carries a tremendous societal and individual burden, posing significant challenges for public health systems worldwide due to its high morbidity and mortality. Due to aging and multimorbidity but also in the wake of important progress in deciphering the heterogeneous disease endotypes, an individualized approach to the prevention and management of COPD is necessary.

AREAS COVERED

This article tackles relevant immunization strategies that are available or still under development with a focus on the latest evidence but also controversies around different regional immunization approaches. Further, we present the crossover between chronic lung inflammation and lung microbiome disturbance as well as its role in delineating COPD endotypes. Moreover, the article attempts to underline endotype-specific treatment approaches. Lastly, we highlight non-pharmacologic prevention and management programs in view of the challenges and opportunities of the COVID-19 era.

EXPERT OPINION

Despite the remaining challenges, personalized medicine has the potential to offer tailored approaches to prevention and therapy and promises to improve the care of patients living with COPD.
