BP in both arms at once is best practice

INTER-ARM differences in blood pressure (BP) should be assessed simultaneously in both arms using at least one automated device, researchers say, based on data from a meta-analysis.

While double-arm measurements are advised in guidelines worldwide, the optimum way to perform them is not clearly described, the researchers said.

Alarmingly, studies have suggested few GPs or hospital physicians follow even the most critical aspects of BP measurement, they said.

The researchers evaluated 22 studies on inter-arm measurement, entailing 14,540 people with a median age of 56 years and covering a diverse population including pregnant women, and patients with hypertension and diabetes, as well as normotensive patients.

Pooled data suggested sequential measurements led to a significantly higher prevalence of inter-arm
