The effects of referral letters on increasing the likelihood of patients obtaining hypertension follow-up assessments are presented. Seventy-four patients with elevated diastolic blood pressure (between 95 and 120 mm Hg), who were administratively ineligible for longitudinal care from the Veterans Administration, were randomized into one of four groups: a patient letter; a physician letter; both patient and physician letters; or no letter (control group). No evidence of interaction between the patient and physician letters was found. Results revealed that nearly twice as many patients (63%) receiving the patient letter returned for a hypertension evaluation as compared with those who did not (33%). No difference was found between the physician letter and no physician letter conditions. These findings suggest that patient-directed referral letters can increase the likelihood of follow-up in both previously detected and newly detected cases.
本文介绍了转诊信对增加患者获得高血压随访评估可能性的影响。74例舒张压升高（95至120毫米汞柱）的患者，在行政上不符合退伍军人管理局纵向护理的条件，被随机分为四组之一：患者信组；医生信组；患者信和医生信都有的组；或无信组（对照组）。未发现患者信和医生信之间存在相互作用的证据。结果显示，收到患者信的患者中，返回进行高血压评估的患者数量（63%）几乎是未收到患者信患者（33%）的两倍。医生信组和无医生信组之间未发现差异。这些发现表明，针对患者的转诊信可以增加既往已确诊和新确诊病例进行随访的可能性。
