The purpose of this study was to evaluate the cross-sectional relationship between physician knowledge of hypertension guidelines and blood pressure (BP) control. The authors evaluated a sample of primary care faculty (n=32) and a sample of their patients (n=613). When treating patients as independent observations, the authors found an inverse relationship (r=-0.524; p=0.002) where higher knowledge scores were associated with lower BP control. The authors conducted a multivariate analysis to accommodate the nonindependence due to random physician effects and found that there was no longer a significant association between knowledge and BP control, but there was still a trend (odds ratio=0.84; p=0.130). This study demonstrates that there is no evidence that high knowledge of hypertension guidelines will improve BP control rates and that higher knowledge may actually be associated with lower BP control. Strategies that are designed only to improve knowledge of hypertension guidelines are insufficient to improve BP control rates.
本研究的目的是评估医生对高血压指南的了解与血压（BP）控制之间的横断面关系。作者评估了一组初级保健教员样本（n = 32）及其一组患者样本（n = 613）。当将患者作为独立观察对象时，作者发现了一种负相关关系（r = -0.524；p = 0.002），即知识得分越高，血压控制越低。作者进行了多变量分析，以适应由于医生随机效应导致的非独立性，结果发现知识与血压控制之间不再存在显著关联，但仍有趋势（优势比 = 0.84；p = 0.130）。本研究表明，没有证据表明对高血压指南的深入了解会提高血压控制率，而且更高的知识水平实际上可能与更低的血压控制相关。仅旨在提高对高血压指南了解的策略不足以提高血压控制率。
