Improvement of hypertension management by structured physician education and feedback system: cluster randomized trial.
2010
IntroductionWe aimed to assess whether hypertension management with a structured physician information program and a feedback system leads to improved blood pressure (BP) control and cardiovascular outcomes.MethodsCluster randomized (3: 1), open, monitored, multicenter trial in Germany. Primary care-based physicians in the information group (IG) received detailed training on hypertension guidelines, feedback on target-level attainment, and a reminder to intensify treatment after each patient visit, whereas the observation/control group (CG) did not receive any such measures. A three-level mixed model was developed. Time-independent level differences between groups, group-independent changes, and nonparallel group-specific changes over time were tested.ResultsA total of 15 041 (78.1%) hypertensive patients were in the IG and 4213 (21.9%) in the CG. By 1-year follow-up, 82.9% of patients in the IG and 81.5% in the CG remained in the study. The guideline-oriented BP target was attained by 56.8% in the IG and...
