Abstract
ABSTRACT: Despite the availability of effective medications, the majority of pediatric and adult patients with persistent asthma have uncontrolled symptoms. This has been attributed to patient nonadherence and poor self-management, but clinicians also contribute through inaccurate assessment of asthma and lack of familiarity with best practice guidelines for medication management. Thus, improving patient outcomes will require improving clinical management by health care providers, including utilization of evidence-based practice guidelines. In this report, we briefly summarize key points of the national guidelines for asthma management and delineate important changes enacted by 2020 Expert Panel Report-4 updates. These include revised recommendations on the use of fractional exhaled nitric oxide testing, indoor allergen mitigation, bronchial thermoplasty, adjunctive immunotherapy, and important modifications to medication management that are likely to have widespread impact on prescribing throughout the United States. In particular, for all patients aged five years and older taking stepwise therapy levels 3-4, it is now recommended to use Single Maintenance and Reliever Therapy, whereas the use of intermittent inhaled corticosteroids (ICSs) administered at the same time as short-acting beta agonist is recommended for step 2 to reduce symptom burden, improve control, and minimize total ICS dose.
