Key result
Cuffless BP devices require rigorous validation for accuracy, access, and privacy before clinical use.
Why the study?
Conventional cuff blood pressure measurement is difficult for patients due to inconvenience and discomfort, but the clinical validity and key implementation issues of emerging cuffless devices require evaluation.
Are cuffless blood pressure measurement devices accurate and ready for clinical use compared to conventional cuff devices?
Are cuffless blood pressure measurement devices accurate and ready for clinical use compared to conventional cuff devices?
Clinicians and patients should continue using validated cuff BP devices until cuffless technologies are rigorously validated.
Clinicians should retain validated cuff devices; leaves open cuffless adoption pending rigorous validation studies.
Importance: Hypertension is a primary modifiable risk factor for cardiovascular death and disability. Accurate blood pressure (BP) measurement is essential for the diagnosis and treatment of hypertension. Conventional BP measurement with cuff devices is recommended but difficult for patients to perform due to inconvenience, discomfort, and challenges with appropriate cuff sizing and measurement protocols. The emergence of cuffless BP devices provides an opportunity to address many of these problems, including inconvenience, patient comfort, positional requirements, and continuous measurement. Observations: Cuffless BP measurement devices are appealing to patients and clinicians, but validation of these technologies is essential before they can be deployed for clinical use. Key issues that remain include accuracy with risk of undertreatment or overtreatment, equitable access for low- and middle-income countries and minoritized populations, data privacy concerns, and how the devices will be deployed in clinical practice. Conclusions: Clinicians and patients should only use validated BP cuff devices until cuffless BP measurement devices are appropriately tested and validated.

Yang et al. (2025) conducted a review in Hypertension. Cuffless blood pressure measurement devices vs. Conventional cuff devices was evaluated. Cuffless blood pressure measurement devices require appropriate testing and validation for accuracy, equitable access, and data privacy before they can be recommended for clinical use.
