Randomized Controlled Trial Multicenter Study Comparative Study
Cluster-randomized controlled trial of oscillometric vs. manual sphygmomanometer for blood pressure management in primary care (CRAB).
Although mercury sphygmomanometers are seen as the gold standard instrument for blood pressure (BP) measurement, they are being withdrawn due to safety concerns. CRAB was a cluster-randomized controlled trial in 24 family practices in Tasmania, Australia, which aimed to determine the effect of an oscillometric device on BP management. ⋯ Although digit preference was largely eliminated by oscillometric measurement, prescribing behavior was mediated by SBP.
