Asthma is a prevalent chronic disease with a high degree of morbidity, mortality, and health care utilization in the United States.1 Certain racial and ethnic groups, including Black and Latino populations, are disproportionately affected by asthma.2,3 These groups continue to face significantly higher rates of asthma symptom burden,4 decreased rates of controller use,5 and higher rates of asthma emergency department visits, hospitalizations, and mortality.6,7 There are multiple reasons behind these health disparities including socioeconomic factors, lack of access to care, and bias within the institution of medicine and society.4 Bias in medicine and society relates to the direct actions of providers and health care systems, including individual implicit bias8 and structural racism at institutional and organizational levels leading to worse health outcomes.9,10

Health care technology strategies remain an ever-emerging opportunity to improve population health. These tools have been implemented across various diseases and include a multitude of methods, including text messaging, audio/visual materials, electronic educational programs, medical device monitors, and telehealth, among others.11 As internet access becomes more ubiquitous, technology-based health care interventions will continue to grow more prevalent. Technology has the potential to decrease health disparities; alternatively, it may exacerbate such disparities due to a lack of digital equity, where certain demographic groups do not have the same access to reliable and affordable internet and communication services as others.12

Although previous literature has examined the use of technology in asthma care,13 there has not been a comprehensive analysis of the use of technology in asthma for historically marginalized populations. The purpose of this article was to perform a scoping review examining the use of technology in asthma in historically marginalized populations. The objective was to identify the populations such interventions have been studied in, to describe the specific types of interventions that are being performed, and to identify the efficacy of these interventions in improving asthma outcomes.
