PMID 40529464WHAT IT FOUND
Digital health interventions for uncontrolled hypertension improved self-management and blood pressure control, reduced cardiovascular risk, and two studies showed cost-effectiveness.
They worked best when combined with provider support, especially nurse feedback and consultation, rather than stand-alone.
Key findings
01DHIs that supported self-management commonly included multiple components: health education, reminders, self-monitoring, feedback and consultation, and instrumental support.
02Combining DHIs with healthcare provider support improved adherence to self-management compared with stand-alone DHIs.
03Nurses were among providers who delivered interactive feedback and consultation in the reviewed DHIs.

What it does not show
The search was limited to English and Thai publications, so relevant studies may have been missed. Only two studies reported cost-effectiveness, so the economic finding rests on a small evidence base. Included studies varied by country, format and intensity, so it is difficult to identify which component produced the benefit. The review included both randomized and quasi-experimental studies, and the quality appraisal showed some unclear or negative items for blinding and follow-up. Most studies were conducted in upper-middle to high-income countries, so findings may not transfer to lower-income settings.
Declared interests
The authors declared no known competing financial interests or personal relationships.
The easy way to misread this
Do not conclude that a specific digital tool or component caused the benefit. The interventions were multicomponent, and the contribution of any component cannot be separated. Do not treat cost-effectiveness as settled, because only two studies reported it.
