How this fits in

Self-monitoring blood pressure (BP) is common, but the accuracy of patients’ own monitors is currently unclear. This study provides evidence that the accuracy of some monitors used at home is similar to that of those used in professional settings, albeit with more frequent cuff failure. The study also found that validated monitors, those costing >£10, and those in use for ≤4 years were more likely to perform better. Clinicians can be reassured that patients’ own BP monitors are likely to be accurate if a validated model that is ≤4 years old is being used.
