RT Journal Article SR Electronic T1 Assessing blood pressure control in patients treated for hypertension: comparing different measurements and targets JF British Journal of General Practice JO Br J Gen Pract FD British Journal of General Practice SP 375 OP 377 VO 56 IS 526 A1 Gillian Manning A1 Andrew Brooks A1 Barbara Slinn A1 Michael W Millar-Craig A1 Richard Donnelly YR 2006 UL http://bjgp.org/content/56/526/375.abstract AB We examined how different methods and definitions of blood pressure affect the achievement of targets in general practice. There was a wide range in the proportion of treated patients achieving the different target levels recommended by the National Institute for Health and Clinical Excellence, British Hypertension Society and the general medical services contract. Among non-diabetic patients this ranged from; 10–37% (average office), 15–39% (standardised nurse measurement), 11–49% (last recorded) and 31–56% (ambulatory blood pressure). Defining targets without a clear definition of how blood pressure should be measured is largely meaningless and ignoring ambulatory blood pressure results in many patients being classified incorrectly as failing to achieve targets.
