The use of targeted and non-targeted advertising to enrich skin cancer screening samples.
The purpose of this study was to determine whether the risk factor profile of persons attending skin cancer screening clinics could be enriched by appropriate advertising prior to the screening events. Eleven screening clinics were held in eight rural and three suburban communities. Matched communities were randomly assigned to either a target or non-target condition. Targeted communities received an advertisement designed to attract high-risk individuals. The advertisement listed a number of risk factors and encouraged readers with one or more of the listed risk factors to attend the screening. Non-targeted communities received a general advertisement requesting individuals who felt they were at risk of skin cancer to attend the clinic. Risk factor profiles of all participants were measured on the factors listed in the targeted advertisement. The risk factor profiles of screenees and the referral rates for skin lesions requiring attention were significantly higher in the targeted communities than in the non-targeted communities. Lesions suspicious of malignant melanoma or Hutchinson's melanotic freckle also were higher, but not statistically significant, in the targeted communities. Population samples attending community-based skin cancer screening clinics can be enriched by appropriate targeted advertising prior to the screening events. This has important implications for determining the potential cost-effectiveness of population screening programmes.
