In assessing the quality of medical care, techniques were needed which can predict which patients are likely to have good or poor health outcomes. This study describes one way of identifying a subgroup of hypertensive patients whose diastolic blood pressures (DBP) are at high risk of remaining uncontrolled while under treatment. Medical care and patient variables were measured for 123 hypertensive medical clinic patients. Stepwise discriminant analysis identified a set of six variables which best distinguished between patients with well-controlled and uncontrolled DBP. When measurements of these variables were divided into high and low risk responses for uncontrolled DBP, the number of high risk variables was directly related to the proportion of patients with uncontrolled DBP. The variables also predicted DBP control among 63 patients in an entirely different medical care setting.
在评估医疗质量时，需要能够预测哪些患者可能有良好或不良健康结局的技术。本研究描述了一种识别高血压患者亚组的方法，这些患者在接受治疗时舒张压（DBP）仍有很高的未得到控制的风险。对123名高血压门诊患者的医疗护理和患者变量进行了测量。逐步判别分析确定了一组六个变量，这些变量最能区分DBP得到良好控制和未得到控制的患者。当将这些变量的测量结果分为DBP未得到控制的高风险和低风险反应时，高风险变量的数量与DBP未得到控制的患者比例直接相关。这些变量还预测了在完全不同的医疗护理环境中的63名患者的DBP控制情况。
