Long-stay prisoners are not regularly screened for TB in Hong Kong.
To evaluate tuberculosis (TB) screening in prison.
All prisoners in a maximum security prison as of 31 October 2001 were screened by chest radiograph (CXR), except for those being followed up for TB or examined by CXR in the last 6 months.
A total of 814 male prisoners aged 34.6 +/- 9.6 (mean +/- SD) years were successfully screened. Of 53 cases (6.51%) with radiographic abnormalities, 10 active TB cases (8 culture-negative, 2 culture-positive) were diagnosed, giving an overall yield of 1.23% (95%CI 0.59-2.26). There was no statistical difference in age, ethnicity, place of birth or residency status between those with and those without TB (all P > 0.05). Incarceration > or = 2 years, being in current prison > or = 2 years and not having CXR in last 2 years were associated with TB in univariate analysis (all P < 0.05), but only the last remained an independent predictor in multiple logistic regression (OR 16.8, 95%CI 2.1-132.9, P = 0.008). In that group, the yield was 3.1% (95%CI 1.42-5.89). No further cases were detected in the subsequent 2 years.
CXR screening of long-stay prisoners gave a high yield in this study.
在香港，长期服刑囚犯未定期接受结核病筛查。
评估监狱中的结核病筛查情况。
截至2001年10月31日，对一所高度设防监狱中的所有囚犯进行胸部X光（CXR）筛查，但不包括那些正在接受结核病随访或在过去6个月内已接受过CXR检查的囚犯。
共成功筛查了814名年龄为34.6±9.6（均值±标准差）岁的男性囚犯。在53例（6.51%）有影像学异常的病例中，确诊了10例活动性结核病病例（8例培养阴性，2例培养阳性），总体检出率为1.23%（95%可信区间0.59 - 2.26）。结核病患者与非结核病患者在年龄、种族、出生地或居住状况方面均无统计学差异（所有P>0.05）。在单因素分析中，监禁≥2年、在当前监狱服刑≥2年以及过去2年内未进行CXR检查与结核病相关（所有P<0.05），但在多因素逻辑回归中，只有最后一项仍是独立预测因素（比值比16.8，95%可信区间2.1 - 132.9，P = 0.008）。在该组中，检出率为3.1%（95%可信区间1.42 - 5.89）。在随后的2年中未发现更多病例。
在本研究中，对长期服刑囚犯进行CXR筛查的检出率较高。
