Key result
Nurses record blood pressure with end digit zero ~92% more frequently than physicians.
Why the study?
Does the type of healthcare worker (nurse vs physician) influence the prevalence of end digit preference in blood pressure measurement?
Population
114 patients seen over a two-month period at a hypertension specialty clinic
Design
Cross-sectional

Digit preference appears higher in nurse-performed BP readings; leaves open whether provider-specific training improves measurement accuracy.

Does the type of healthcare worker (nurse vs physician) influence the prevalence of end digit preference in blood pressure measurement?
Absolute Event Rate: 98.5% vs 51.2%
p-value: p=< 0.001
There is a high prevalence of end digit preference for zero in blood pressure measurements, particularly among nurses compared to physicians, highlighting the need for retraining and monitoring.
Ayodele et al. (2012) conducted an observational in Hypertension (n=114). Blood pressure measurement by nurses vs. Blood pressure measurement by physicians was evaluated on Preference for end digit zero in systolic blood pressure readings (p=< 0.001). Blood pressure measurement by nurses showed a significantly higher preference for end digit zero in systolic (98.5% vs 51.2%) and diastolic (98.5% vs 64.3%) readings compared to physicians (p<0.001).
