This study aimed to assess the knowledge, attitude, and practice (KAP) of high-risk populations toward lung cancer screening in Lanzhou, China. Using convenience sampling, this cross-sectional study enrolled outpatients at high-risk for lung cancer at Lanzhou University Second Hospital between November 2022 and March 2023. An anonymous, self-administered online questionnaire was distributed to each participant via the Sojump website (https://www.wjx.cn/), comprising 40 items to collect demographic information and evaluate KAP toward lung cancer screening. The analyses were descriptive. A total of 577 participants (average age of 61.8 ± 7.1 years; 306 males) were included in the study. The participants' scores for KAP were 4.9 ± 2.2, 27.4 ± 3.0, and 7.0 ± 2.1, respectively. Participants with occupational exposure had significantly lower knowledge score (3.3 ± 2.4 vs 5.2 ± 2.1, P < .001), and practice score (5.6 ± 2.4 vs 7.3 ± 1.9, P < .001) than those without occupational exposure. Participants with smoking or passive smoking history had significantly higher attitude scores (27.6 ± 2.9 vs 25.8 ± 3.2, P < .001) and practice scores (7.1 ± 2.0 vs 6.5 ± 2.5, P = .014) than those without smoking history. A total of 360 (62.4%) participants endorsed the doctors' counseling on lung cancer screening, and 355 (61.5%) participants were willing to have screening for lung cancer as doctors advised. The study revealed that 390 (67.6%) participants identified low-dose computed tomography as the appropriate method for lung cancer screening, while 356 (61.7%) participants believed that X-rays were a reliable screening method for lung cancer. However, 365 (63.3%) participants thought that the treatment outcomes for early and late-diagnosed lung cancer were the same. Additionally, 416 (72.10%) participants believed that annual lung cancer CT scanning is unnecessary. On the other hand, 339 (58.8%) participants expressed concerns about exposure to radiation from CT scans, while 349 (60.5%) participants were worried about the cost of lung cancer screening. Only 142 (24.6%) participants reported having undergone annual lung cancer screening. The high-risk population had limited knowledge and insufficient attitude and practice toward lung cancer screening in Lanzhou, China.
本研究旨在评估中国兰州高危人群对肺癌筛查的知识、态度和实践（KAP）。采用便利抽样法，本横断面研究于 2022 年 11 月至 2023 年 3 月期间招募兰州大学第二医院的肺癌高危门诊患者。通过 Sojump 网站（https://www.wjx.cn/）向每位参与者发放匿名、自我管理的在线问卷，共 40 个项目，收集人口统计学信息并评估对肺癌筛查的 KAP。分析采用描述性方法。共有 577 名参与者（平均年龄 61.8±7.1 岁；306 名男性）纳入研究。参与者的 KAP 得分分别为 4.9±2.2、27.4±3.0 和 7.0±2.1。有职业暴露的参与者知识得分（3.3±2.4 分比 5.2±2.1 分，P<0.001）和实践得分（5.6±2.4 分比 7.3±1.9 分，P<0.001）明显较低。有吸烟或被动吸烟史的参与者态度得分（27.6±2.9 分比 25.8±3.2 分，P<0.001）和实践得分（7.1±2.0 分比 6.5±2.5 分，P=0.014）明显较高。共有 360（62.4%）名参与者认可医生对肺癌筛查的建议，355（61.5%）名参与者愿意按照医生建议进行肺癌筛查。研究发现，390（67.6%）名参与者认为低剂量计算机断层扫描是肺癌筛查的合适方法，而 356（61.7%）名参与者认为 X 射线是可靠的肺癌筛查方法。然而，365（63.3%）名参与者认为早期和晚期诊断的肺癌治疗效果相同。此外，416（72.10%）名参与者认为每年进行肺癌 CT 扫描没有必要。另一方面，339（58.8%）名参与者对 CT 扫描辐射暴露表示担忧，349（60.5%）名参与者担心肺癌筛查的费用。只有 142（24.6%）名参与者报告每年进行肺癌筛查。中国兰州高危人群对肺癌筛查的知识有限，态度和实践不足。
