The US Preventive Services Task Force recommends that individuals at high risk for lung cancer consider benefits and harms before pursuing lung cancer screening. Medical centers develop websites for their lung cancer screening programs, but to date little is known about the websites' portrayal of benefits and harms or what next steps they recommend for individuals considering screening.
To assess the presentation of potential benefits and harms and recommended next steps on lung cancer screening program websites.
DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional content analysis of 162 lung cancer screening program websites of academic medical centers (n = 81) and state-matched community medical centers (n = 81) that were randomly selected from American College of Radiology lung cancer screening-designated centers was conducted. The study was performed from December 1, 2018, to January 31, 2019.
Website presentation of screening-associated benefits and harms was the primary outcome. Benefit was defined as any description related to the potential reduction in lung cancer mortality. Harms were based on the US Preventive Services Task Force recommendations and included false positives, false negatives, overdiagnosis, radiation exposure, and incidental findings. The secondary outcome was next steps that are recommended by websites.
Overall, the 162 lung cancer screening program websites described the potential benefits more frequently than they described any potential harms (159 [98%] vs 78 [48%], P < .01). False-positive findings were the most frequently reported (72 [44%]) potential harm. Community centers were less likely than academic centers to report any potential harm (32 [40%] vs 46 [57%], P = .03), potential harm from radiation (20 [25%] vs 35 [43%], P = .01), and overdiagnosis (0% vs 11 [14%], P < .01). One hundred nineteen websites (73%) did not explicitly recommend that individuals personally consider the potential benefits and harms of screening; community centers were less likely than academic centers to give this recommendation (15 [19%] vs 28 [35%], P = .02). Most institutions (157 [97%]) listed follow-up steps for screening, but few institutions (35 [22%]) recommended that individuals discuss benefits and harms with a health care professional.
Information on public-facing websites of US lung cancer screening programs appears to lack balance with respect to portrayal of potential benefits and harms of screening. Important harms, such as overdiagnosis, were commonly ignored in the sites evaluated, and most of the centers did not explicitly guide individuals toward a guideline-recommended, shared decision-making discussion of harms and benefits.
美国预防服务工作组建议,高危肺癌人群在考虑肺癌筛查前,权衡利弊。医疗机构为其肺癌筛查项目建立了网站,但迄今为止,人们对这些网站在描述益处和危害方面的情况,以及它们对考虑筛查的个人推荐的下一步措施了解甚少。
评估肺癌筛查项目网站对潜在益处和危害的呈现方式,以及对考虑筛查的个人推荐的下一步措施。
设计、地点和参与者:对随机选取的美国放射学院肺癌筛查指定中心的 81 家学术医疗中心和 81 家州级社区医疗中心的 162 个肺癌筛查项目网站进行了横断面内容分析(n=81)。该研究于 2018 年 12 月 1 日至 2019 年 1 月 31 日进行。
网站呈现的与筛查相关的益处和危害是主要结局。益处被定义为任何与降低肺癌死亡率相关的描述。危害基于美国预防服务工作组的建议,包括假阳性、假阴性、过度诊断、辐射暴露和偶然发现。次要结局是网站推荐的下一步措施。
总体而言,162 个肺癌筛查项目网站描述潜在益处的频率高于描述任何潜在危害的频率(159[98%]与 78[48%],P<0.01)。假阳性发现是最常报告的潜在危害(72[44%])。社区中心比学术中心更不可能报告任何潜在危害(32[40%]与 46[57%],P=0.03)、辐射相关的潜在危害(20[25%]与 35[43%],P=0.01)和过度诊断(0%与 11[14%],P<0.01)。119 个网站(73%)没有明确建议个人考虑筛查的潜在益处和危害;社区中心比学术中心更不可能给出这一建议(15[19%]与 28[35%],P=0.02)。大多数机构(157[97%])列出了筛查的后续步骤,但很少有机构(35[22%])建议个人与医疗保健专业人员讨论益处和危害。
美国肺癌筛查项目面向公众的网站信息在描述筛查的潜在益处和危害方面似乎缺乏平衡。在评估的网站中,一些重要的危害,如过度诊断,通常被忽视,而且大多数中心没有明确引导个人进行指南推荐的、关于危害和益处的共同决策讨论。
