Methods: In 2021-2022, a cohort (n=123) of adults living with SCD in Sierra Leone were surveyed as part of the INSIGHTS Study (NCT02156102). A mixed-methods recruitment strategy was used, including via public service announcements hosted on local radio stations, information disseminated via a WhatsApp group, and snowball sampling. Recruitment was conducted in two settings, one urban (Freetown) and one rural (Kono). Participants completed this cross-sectional study from September 2021-February 2022. Questions were asked regarding participants’ perspectives and knowledge of hydroxyurea, the current standard of care treatment for SCD, and novel experimental gene therapy.
Results: The mean age of respondents was 23.6 years (range 18-63). The majority of respondents were female (65.6%), educated at or above the senior secondary school level (78.7%), and students (70.3%). Respondents predominantly had the HbSS genotype (89.4%). Most study participants lacked awareness of hydroxyurea and gene therapy (93.5% had never heard of hydroxyurea; 95.1% had never taken hydroxyurea; 94.8% had never heard of gene therapy for SCD treatment) (Table 1). Despite this gap in knowledge, the majority (95.0%) agreed that genetic research is a necessary way to learn about treatments for SCD (Table 1).
Discussion: Our results highlight disparities in current standard of care treatment and knowledge in a country with a high prevalence of SCD. While our cohort indicated a favorable attitude toward SCD research and a willingness to participate, these results highlight a significant barrier for successful implementation of current treatment and the adoption of curative genetic therapies in limited resource settings like Sierra Leone. Given the significant lack of knowledge around hydroxyurea, it is important that public health initiatives and research should be directed toward both established standard of care and creating awareness of experimental therapies.
