Eight hundred and fifty-four patients of 928 who had attended a mass radiographic tuberculosis survey and in whom the diagnosis of non-tuberculous lung disease had been made, were located two years after the survey. This was the second follow-up survey of this group, the first having been at four months. The majority of patients were well, but 247 were ill and 101 had died. Serious non-tuberculous chest disease can be diagnosed with accuracy at mass surveys but the benefit to the patient of having these conditions detected is less clear. Serious progressive conditions that lead to death or ill health within two years appear to become symptomatic and force the sufferer to seek medical advice at about the same time that they are detected at mass surveys. This fact, coupled with the low yield of previously unknown tuberculosis, makes the future use of general mass radiographic surveys questionable in areas with good medical services. Evidence is presented that suggests screening directed to specific age groups may be more productive.
在928名参加大规模肺结核X线检查的患者中，有854名被诊断为非结核性肺病，在检查两年后对这些患者进行了追踪。这是该组的第二次随访调查，第一次是在四个月时进行的。大多数患者情况良好，但有247名患者患病，101名已经死亡。在大规模检查中可以准确诊断出严重的非结核性胸部疾病，但这些疾病被查出对患者的益处尚不明确。在两年内导致死亡或健康不佳的严重进展性疾病似乎会出现症状，并迫使患者在大规模检查发现这些疾病的同时就医。这一事实，再加上先前未知的结核病检出率低，使得在医疗服务良好的地区未来使用普通大规模X线检查存在疑问。有证据表明，针对特定年龄组的筛查可能更有成效。
