In 1964, 219,085 persons were examined during a tuberculosis survey in Vancouver, B.C. One hundred and fifteen new cases of tuberculosis and 929 cases of significant non-tuberculous lung disease were found. In a four-month follow-up of the non-tuberculous cases it was found that of the 742 patients who had named a physician when examined 26.6% had not made contact with him. Of those who did contact the physician, the follow-up was considered "poor" in only 30 patients (2.1%). Seventeen patients had died in the four-month interval and 81 who could not be located after the initial survey were considered "lost". Rates were determined for 37 diagnoses per 1000 patients screened. The most common diagnosis was localized pulmonary fibrosis (1.69/1000). Carcinoma was found in 0.30/1000 and solitary lung density in 0.17/1000 population screened.
1964年，在不列颠哥伦比亚省温哥华市进行的一次结核病调查中，对219,085人进行了检查。发现了115例新的结核病病例和929例严重的非结核性肺部疾病病例。在对非结核病例进行的为期四个月的随访中发现，在接受检查时已指定医生的742名患者中，有26.6%的人未与该医生联系。在那些确实联系了医生的患者中，只有30名患者（2.1%）的随访情况被认为“不佳”。在这四个月期间有17名患者死亡，在初次调查后无法找到的81名患者被认为“失访”。每1000名接受筛查的患者中有37种诊断的发生率被确定。最常见的诊断是局限性肺纤维化（1.69/1000）。每1000名接受筛查的人群中发现癌症的比例为0.30/1000，孤立性肺密度的比例为0.17/1000。
