A screening campaign for high blood pressure was carried out in the Victorian township of Queenscliff in 1975. In late 1981, 99% of the population screened was identified as being alive or dead and, in the latter case, the date of death was ascertained. Survival curve analysis showed a significantly worse prognosis for those subjects diagnosed as hypertensive, despite a high prevalence of treatment and a specific screening programme. It is suggested that the results of controlled trials do not translate easily to uncontrolled situations and that mass-screening campaigns may not be an effective way of intervening in countries with more open medical systems.
1975年，在维多利亚州的昆斯克利夫镇开展了一项高血压筛查活动。1981年末，已查明99%接受筛查的人口的存活或死亡情况，对于后者，还确定了死亡日期。生存曲线分析表明，尽管治疗普及率很高且有特定的筛查方案，但被诊断为高血压的患者预后明显较差。有人认为，对照试验的结果不易转化为非对照情况，而且在医疗体系更为开放的国家，大规模筛查活动可能不是一种有效的干预方式。
