BACKGROUND/OBJECTIVES: Some international guidelines recommend a risk-based approach to screening for melanoma, but few suggest how to account for multiple risk factors or how to implement risk-based screening in practice. This study investigated the acceptability and feasibility of identifying patients at increased risk of melanoma in Australian general practice using a self-completed risk assessment tool. Stratification of risk was based on the validated Williams melanoma risk prediction model.
Patients and companions aged 18 or older in Australian general practices were approached in the waiting room and invited to enter information about their melanoma risk factors into the tool using an iPad. Acceptability was measured by the proportion of people willing to participate from those invited and feasibility by the number of people able to complete the tool unaided. Risk of developing melanoma was stratified into four risk categories using the Williams model.
1535 (90.4%) participants were recruited from two general practices. Only 200 participants (13%) needed assistance to complete the tool. The mean risk score for participants was 15.2 (±SD 9.8). The Williams model estimated between 5% and 19% of the sample were at increased risk accounting for an estimated 30% to 60% of future incident melanomas.
A risk-stratified tool using the Williams model was acceptable and feasible for patients to self-complete in general practice clinics. This could be an effective way to identify people in primary care for implementing risk-based targeted melanoma screening and prevention.
背景/目的:一些国际指南建议采用基于风险的方法来筛查黑色素瘤,但很少有指南建议如何考虑多种风险因素,或如何在实践中实施基于风险的筛查。本研究调查了使用自我完成的风险评估工具在澳大利亚普通诊所识别黑色素瘤风险增加的患者的可接受性和可行性。风险分层基于经过验证的 Williams 黑色素瘤风险预测模型。
在澳大利亚普通诊所的候诊室中接触到 18 岁或以上的患者及其同伴,并邀请他们使用 iPad 将有关其黑色素瘤风险因素的信息输入工具。可接受性通过受邀者中愿意参与的人数来衡量,可行性通过能够独立完成工具的人数来衡量。使用 Williams 模型将黑色素瘤发病风险分为四个风险类别。
从两家普通诊所招募了 1535 名(90.4%)参与者。只有 200 名参与者(13%)需要协助才能完成工具。参与者的平均风险评分是 15.2(±9.8)。Williams 模型估计,该样本的 5%至 19%处于较高风险,预计占未来黑色素瘤病例的 30%至 60%。
使用 Williams 模型进行风险分层的工具在普通诊所中对患者来说是可接受且可行的,患者可以自行完成。这可能是一种有效的方法,可以在初级保健中识别出需要进行基于风险的靶向黑色素瘤筛查和预防的人群。
