Key result
Video-based evaluation shows systolic BP deviation remains acceptable while diastolic deviation decreases over time.
Why the study?
A method for evaluating within-observer variability in blood pressure measurement was tested to improve quality control.
Comparison
Within-observer variability versus accepted correct readings
Design
Observational study using repeated measurement ANOVA
Follow-up
Three follow-up evaluations

Should not yet change BP measurement training; leaves open prospective validation of video-based variability assessment.
Observational (n=6)
A video-based method for evaluating within-observer variability in blood pressure measurement showed that diastolic measurement variability improves with repeated evaluations.
Toromo et al. (1995) conducted an observational in Blood pressure measurement variability (n=6). Video-based evaluation of within-observer variability was evaluated on Within-observer variability (deviation from correct readings). Video-based evaluation showed systolic blood pressure deviation remained below the accepted limit, while diastolic deviation initially exceeded the limit but decreased over three follow-ups.
