Conventional versus automated measurement of blood pressure in primary care patients with systolic hypertension: randomised parallel design controlled trial. BMJ 2011;342:d286.OpenUrlAbstract/FREE Full Text Despite the use of gold standard equipment such as mercury sphygmomanometers in primary care for the measurement of blood pressure, accuracy remains a problem. This is due to a combination of system (eg, lack of calibration of instruments), physician (eg, observer error) and patient (eg, sympathetic drive) factors. Programmable automatic and semiautomatic oscillometric devices are likely to replace such devices because of occupational health concerns with the use of mercury. This is a cluster randomised controlled study of an automated oscillometric blood pressure device method of determining blood pressure (intervention) versus usual manual measurement (control) in primary care. Both arms ambulatory blood pressure (ABP) measurements were also taken. The study included 555 patients with systolic hypertension (treated and untreated) and no serious comorbidities under the care of 88 primary care physicians in 67 Canadian primary care … ER -
