Informed decision-making approaches to cancer screening emphasise the importance of decisions being determined by individuals' own values and preferences. However, advice from a trusted source may also contribute to autonomous decision-making. This study examined preferences regarding a recommendation from the NHS and information provision in the context of colorectal cancer (CRC) screening.
In face-to-face interviews, a population-based sample of adults across Britain (n=1964; age 50-80 years) indicated their preference between: (1) a strong recommendation to participate in CRC screening, (2) a recommendation alongside advice to make an individual decision, and (3) no recommendation but advice to make an individual decision. Other measures included trust in the NHS and preferences for information on benefits and risks.
Most respondents (84%) preferred a recommendation (47% strong recommendation, 37% recommendation plus individual decision-making advice), but the majority also wanted full information on risks (77%) and benefits (78%). Men were more in favour of a recommendation than women (86% vs 81%). Trust in the NHS was high overall, but the minority who expressed low trust were less likely to want a recommendation.
Most British adults want full information on risks and benefits of screening but they also want a recommendation from an authoritative source. An 'expert' view may be an important part of autonomous health decision-making.
以知情决策为基础的癌症筛查方法强调了决策应取决于个人的价值观和偏好。然而，来自可信赖的来源的建议也可能有助于做出自主决策。本研究考察了在结直肠癌（CRC）筛查背景下，对来自英国国家医疗服务体系（NHS）的建议和信息提供的偏好。
在面对面访谈中，英国各地的成年人（n=1964；年龄 50-80 岁）基于以下三种情况表示了自己的偏好：（1）强烈建议参加 CRC 筛查；（2）建议并提供个人决策的建议；（3）不建议但提供个人决策的建议。其他措施包括对 NHS 的信任度以及对益处和风险信息的偏好。
大多数受访者（84%）更喜欢建议（47%的强烈建议，37%的建议加个人决策建议），但大多数人也希望获得关于风险（77%）和益处（78%）的完整信息。男性比女性更倾向于建议（86%比 81%）。总体而言，对 NHS 的信任度较高，但少数表示信任度较低的人不太希望得到建议。
大多数英国成年人希望获得有关筛查风险和益处的全面信息，但他们也希望得到权威来源的建议。“专家”的观点可能是自主健康决策的重要组成部分。
