Abstract/OtherAbstract:
Background: Computer-based clinical decision support aims to improve the quality of patient care. The utility of decision support for improving blood pressure control in hemodialysis patients is unknown. Methods: This was a nonrandomized controlled trial of adult patients receiving chronic in-center hemodialysis during the period of April 1, 2005, to September 30, 2006, in 1 of the 2 major university-based renal programs in Alberta, Canada. Physicians in the intervention center were provided with twice-monthly audits and printed management suggestions based on guideline-recommended blood pressure targets. The same data were available to physicians in the control group but without audit and feedback decision support. Results: Eight hundred and thirty hemodialysis patients were receiving dialysis treatment at the time the study was initiated. Preintervention and postintervention blood pressure data were available for 361 patients. The primary outcome, the proportion of postdialysis systolic blood pressures at target over 12 months, did not differ between the intervention and the control programs (unadjusted odds ratio 0.59; 95% confidence interval [95% CI], 0.34-1.02, p = 0.06; adjusted odds ratio 0.62; 95% CI, 0.35-1.11, p = 0.11). There was no significant difference between the intervention and control groups in other measures of blood pressure such as the mean change in postdialysis systolic blood pressures (unadjusted mean difference 4 mm Hg, 95% CI, -1 to 9, p = 0.36; adjusted mean difference 2 mm Hg, 95% CI, -1 to 5, p = 0.19). Conclusions: In this population of chronic hemodialysis patients, a computer-based clinical decision support system was not associated with improved blood pressure control.
