Guidelines for the management of asthma in adults and adolescents: Position statement of the South African Thoracic Society - 2021 update.

Asthma prevalence is increasing worldwide, and surveys indicate that most patients in developed and developing countries, including South Africa, do not receive optimal care and are therefore not well controlled. Standard management guidelines adapted to in-country realities are important to support optimal care. The South African Thoracic Society (SATS) first published a guideline for the management of chronic persistent asthma in 1992, which has subsequently been revised several times. The main aim of the present document was to revise and update SATS' statement on the suggested management of chronic asthma, based on the need to promote optimal care and control of asthma, together with the incorporation of new concepts and drug developments. This revised document reinforces optimal care and incorporates the following primary objectives to achieve the recent advances in asthma care: continued emphasis on the use of inhaled corticosteroids (ICS) as the foundation of asthma treatmentto reduce the reliance on short-acting beta-2 agonist (SABA) monotherapy for asthma symptomsto incorporate the evidence and strategy for the use of the combination of an ICS and formoterol for acute symptom relief (instead of a SABA)to incorporate the evidence and strategy for the use of as-needed ICS-long-acting beta agonists (LABA) for patients with infrequent symptoms or 'mild' asthmato incorporate the evidence and strategy for the use of a long-acting muscarinic antagonist (LAMA) in combination with ICS-LABA; andto incorporate the evidence and strategy for the use of and management with a biologic therapy in severe asthma.
