The updated guidelines by Global obstructive lung disease (GOLD) 2023 for the management of chronic obstructive pulmonary diseases (COPDs) has been released. It is an attempt to provide updated recommendations over previous guidelines, for the diagnosis and treatment of COPD based on newer evidence and hence over 380 new references have been added. However, the updates seemed regressive and unfortunately confusing.
The definition of COPD has been modified and the words "preventable and treatable have been removed." The focus is on "persistent and often progressive airflow obstruction." This is a regressive step as the nihilistic attitude toward COPD which was being battled for the past 20 years by GOLD guidelines seems to have been reignited. The sole focus being on obstruction in spirometry, emphysema (termed as pre-COPD), and preserved ratio impaired spirometry are terminologies of unclear significance in terms of risk of developing into COPD. The term early COPD has been clearly stated to be used for biologically early disease, rather than mild cases. Another term young COPD has been proposed for ages 20–50 years old. Certain etiotypes have been proposed including – COPD-G (genetic), COPD-D (development), COPD-C (cigarette), COPD-P (pollution), COPD-I (infection), COPD-A (asthma), and COPD-U (unknown). This adds to the armamentarium of existing taxonomy including nonsmoker COPD, post tuberculosis COPD (TOPD), asthma-COPD overlap (ACO), and ACO syndrome. The significance of this classification on the diagnosis and treatment of COPD needs more studies.
COPD classification to determine treatment has shifted from A,B,C and D groups to A,B and E groups. The aim here is to clarify that Group C patients (which have less symptoms, but do have exacerbations) are practically a very small group. In fact, most of the patients who present to the outpatient department or even to emergencies are those patients who belong to Group B and erstwhile Group D. The advantage of this new group system is that eventually the patients are started with bronchodilators, put on dual bronchodilators if they have severe symptoms, and can be added with an inhaled corticosteroid making a triple therapy if they have recurrent eosinophilic exacerbations. As there are now only 3 groups in COPD- A, B and E; the future guidelines may see a stepwise treatment algorithm for COPD similar to the stepwise approach used in bronchial asthma.
The role of computed tomography (CT) chest has been clearly defined screening for lung cancer, nodules, emphysema, pulmonary artery hypertension, bone density, assessment for lung volume reduction surgery or interventions, and even for assessing small airway involvement. The guidelines conclude that such wealth of information may be of prognostic significance and thus role is increasing. This statement can lead to potential exploitation of CT chest in all COPD patients, like in COVID-19.
The mortality benefit of triple inhalational therapy, rehabilitation, smoking cessation, oxygen, noninvasive ventilation, and lung volume reduction surgery has been tabulated in the guidelines along with the evidence for the same. This is a welcome step as these are the few therapies which can alter the course and survival of the patient.
To conclude, guidelines keep evolving with emerging evidence. However, it is always necessary to understand the clinical implications of the same to improve patient outcomes.
