Why the study?
Does a computer based clinical decision support system and risk chart reduce cardiovascular risk and blood pressure in hypertensive patients aged 60-79?
Population
614 patients aged between 60 and 79 years with high blood pressure
Comparison
Computer based clinical decision support system… vs Usual care
Design
RCT, Cluster randomised
Key result
A computer-based clinical decision support system did not reduce absolute cardiovascular risk, with patients more likely to have a 5-year risk ≥10% compared to a chart alone (OR 2.3; 95% CI 1.1-4.8).

Computer-based decision support should not supplant risk charts in hypertension; challenges presumed benefits of digital tools for risk reduction.

Does a computer based clinical decision support system and risk chart reduce cardiovascular risk and blood pressure in hypertensive patients aged 60-79?
Effect estimate: OR 2.3 (95% CI 1.1 to 4.8)
A computer-based clinical decision support system did not improve cardiovascular risk or blood pressure control in hypertensive patients, though risk charts alone reduced systolic blood pressure.
Alan Montgomery (2000) conducted an RCT in Hypertension (n=614). Computer based clinical decision support system plus cardiovascular risk chart vs. Cardiovascular risk chart alone or usual care was evaluated on Percentage of patients with a five year cardiovascular risk >=10% (OR 2.3, 95% CI 1.1 to 4.8). A computer-based clinical decision support system did not reduce absolute cardiovascular risk, with patients more likely to have a 5-year risk ≥10% compared to a chart alone (OR 2.3; 95% CI 1.1-4.8).
