      P2.13-012 - Recruitment for Lung Cancer Screening (ID 9673)

      • Abstract

      Background:
      The efficiency of a lung cancer screening program with low dose computed tomography (LDCT) is influenced by the screening uptake. The most efficient method to improve participation rate of individuals in the general population who are eligible for screening has not been determined. We evaluated different methods of recruitment on the participation rate.

      Method:
      The BC lung screening trial is part of the International Lung Screen Trial (ILST) in Canada, Australia, the UK and Hong Kong. ILST aims at defining the optimal selection criteria for LDCT by comparing the relative sensitivity of the US Preventative Services Task Force criteria versus the PLCOm2012 prediction model with 6-year lung cancer risk>=1.5%. Individuals with a chest CT within 2 years are excluded from the screening study. Different methods [social media, radio, newspaper, QuitNow smoking cessation program, BC Lung Association and referrals by general practitioners (GP)] to recruit eligible individuals are compared.

      Result:
      Of the 802 participants referred or self-referred to the study, 364 (41% female, 59% males, 53% ex-smokers and 47% current smokers) were eligible. The largest draw was radio which reached 64% of respondents, however only 29% of these were eligible. General practitioners (GP) reached only 24% but of these 70 % were eligible. 13% had a CT scan within 2 years, and but only 40% would have been eligible via risk criteria (Table 1). Table1. Figure 1



      Conclusion:
      The largest number of eligible participants were referred by their GPs. Media (radio) reached a larger number of participants but many were ineligible. A combined approach of media publicity and GP referrals may be the best way to reach the target the population. Ad hoc screening is likely occurring in the absence of a publicly funded screening program inappropriately exposing participants outside of the criteria.
