MethodsWe looked at the reliability and validity of both the device used for blood pressure measurement and observer performance during measurement to assess the quality of blood pressure determination in the study. The Colin 8800C blood pressure device was tested for performance to Association for the Advancement of Medical Instrumentation standards and for presence of skipped digits. Observer performance was tested by examining adherence to the Secondary Prevention of Small Subcortical Strokes protocol.ResultsThe mean difference (in mmHg) between the Colin device and the average of the two observers was 3.9 (SD 6.7) and− 2.1 (SD 6.1) for systolic and diastolic pressures respectively, thereby meeting Association for the Advancement of Medical Instrumentation requirements. No skipped digits were found between 82–230 and 40–120 mmHg for systolic and diastolic pressures, respectively. Observer performance was excellent with greater than 90% of patients having blood pressure measured consistently according to the protocol.ConclusionsDevice and observer performance in Secondary Prevention of Small Subcortical Strokes is excellent. Interpretation of the Secondary Prevention of Small Subcortical Strokes data for the effect of lowering systolic blood pressure on patient outcomes will not likely be adversely affected by these factors. Accuracy will be monitored throughout the remainder of the trial to ensure that this high quality is maintained.Background
