title: Clinical accuracy of inflationary oscillometry in pregnancy and pre-eclampsia: Omron-MIT Elite.
abstract: OBJECTIVE
  To evaluate the accuracy of the Omron MIT Elite in pregnancy and pre-eclampsia according to the British Hypertension Society protocol (BHS).
  
  
  METHODS
  Prospective observational study.
  
  
  METHODS
  Antenatal clinics and wards at St. Thomas' Hospital (London, UK).
  
  
  METHODS
  Forty-five pregnant women including 15 with pre-eclampsia.
  
  
  METHODS
  Nine sequential same arm blood pressure (BP) measurements were taken from each woman by trained observers, alternating between mercury sphygmomanometry and the test device.
  
  
  METHODS
  Grading criteria of the BHS protocol (A/B grade=pass; C/D=fail).
  
  
  RESULTS
  The Omron MIT Elite achieved a grade A/A in both pregnancy and pre-eclampsia. The mean difference (SD) between the mercury standard and the device in pregnancy was -1.1 (5.2)mmHg and 1.5 (4.8)mmHg for systolic and diastolic BP respectively compared to 0.2 (5.3)mmHg and 2.2 (5.5)mmHg in pre-eclampsia.
  
  
  CONCLUSIONS
  The Omron MIT Elite can be recommended for use in pregnancy and pre-eclampsia according to the BHS protocol. To date, this is the most accurate automated BP device validated in pre-eclampsia.
