Cuffless BP devices have the potential to increase access and overcome barriers to BP screening, particularly for underresourced communities. Individuals from these communities—including people from rural areas, with low income, or from underrepresented racial or ethnic groups—often have a higher prevalence of hypertension and uncontrolled BP than their counterparts and face barriers to accessing health care services, including regular BP monitoring and confirmation of office BP with ABPM.32–34
One of the primary barriers to BP screening in underresourced communities is a lack of health care facilities and trained physicians.35 Cuffless devices, which are often portable and convenient and can be incorporated into everyday objects (eg, watches, smartphones), can be deployed in homes, in community centers, among lay community health workers, and by individuals themselves.4,5,36 This accessibility eliminates the need for individuals to travel long distances to receive basic health screenings, making it easier for residents of rural areas, or areas with shortages of health care professionals, to monitor their out-of-office BP regularly.
Cost is a major barrier hindering access to health care and traditional BP monitoring methods for individuals from underresourced populations, many of whom may be uninsured or underinsured. Cuffless BP devices could theoretically reduce costs, particularly when integrated into wearable or mobile devices that consumers purchase for multiple uses.36 However, because of the limitations of cuffless devices, including the need for calibration with additional purchased devices and insufficient accuracy, cost-effectiveness remains speculative.
