Two years after a hypertension screening survey conducted at Napier in 1973 the blood pressure levels of 350 adults were re-examined. The sample comprised 152 persons previously referred for investigation because of high blood pressure detected during the 1973 survey, a matched control group of 146 normotensives and a small supplementary control group. Of the 152 persons in the referred group 31 (20.4%) were under medical supervision at the time of the 1973 survey, 89 (58.5%) attended a doctor within the next 12 months and 32 (21.1%) took no further action. Two years later the 31 cases previously under medical supervision had remained on therapy but only 43 of the 89 new cases were receiving treatment at the time of re-examination. More than 50% of the cases in the referred group showed a decrease in the mean systolic pressure of 10mmHg or greater over the two-year period compared with 20.5% of the normotensive control group. Only 32% of referred cases were regarded as effectively controlled at the time of re-examination ie had mean systolic pressures less than 160mmHg and mean diastolic pressures less than 95mmHg. The low level of effective control resulting from the earlier survey casts further doubt on the value of mass screening procedures for hypertension.
1973年在纳皮尔进行高血压筛查调查两年后，对350名成年人的血压水平进行了重新检查。样本包括152名因1973年调查中检测出高血压而被转诊进行调查的人、146名血压正常的匹配对照组以及一个小型补充对照组。在被转诊的152人中，1973年调查时31人（20.4%）正在接受医学监督，89人（58.5%）在接下来的12个月内去看了医生，32人（21.1%）未采取进一步行动。两年后，之前接受医学监督的31例患者仍在接受治疗，但重新检查时89例新病例中只有43例正在接受治疗。与血压正常的对照组的20.5%相比，被转诊组中超过50%的病例在两年期间平均收缩压下降了10mmHg或更多。重新检查时，只有32%的被转诊病例被视为得到有效控制，即平均收缩压低于160mmHg且平均舒张压低于95mmHg。早期调查导致的有效控制水平较低，进一步质疑了高血压群体筛查程序的价值。
