[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Background: Clinical dashboards have been promoted as innovative tools to improve health care quality. This study aims to evaluate a clinical dashboard for primary care's impact on health. Objective: The objective of study is to determine whether the use of a clinical dashboard by primary care physicians lowers the average systolic and diastolic blood pressures of hypertensive patients. Methods: We used a quasi-experiment study design. A clinical dashboard created at the University of Missouri for hypertension management was used for two months by a primary care physician for treating hypertensive patients (intervention group). We compared systolic and diastolic blood pressure results from this group with controls in two ways. First, we compared patients' outcomes for this physician with those from other physicians' patients over four years. Second, we compared intervention group patients' results with their own before the "intervention". We used a multivariate regression analysis to estimate blood pressure changes over time due to exposure to clinical dashboards, adjusted for age, gender, diabetes, and nephropathy status. We used "repeated analysis regression" and "mixed model regression" to accommodate clustering due to multiple observations in time. Results: Overall, regression model showed dashboard use lowered significantly patients' SBP (by 5.24 mmHg), while the control group experienced no statistically significant change. Conclusion: Our study shows that using a dashboard in hypertension management could lower patients' blood pressure, even though study limitations prevented us from observing the true effect of dashboard use. Future thorough studies may reveal the true impact of dashboards on the management of hypertensive patients.
