Stakeholder knowledge and attitudes toward the use of predictive genetic testing in South Africa

This study aimed to assess end users ’ (community, medical practitioners and medical students) knowledge and attitudes regarding the use and support of genomic medicine. A descriptive cross-sectional survey was conducted in Kwazulu-Natal (KZN) among 3 groups of stakeholders (n = 170): medical practitioners from both private and public healthcare, medical students from UKZN and community members represented by teachers. Three structured questionnaires using a Likert scale were administered. Responses were stratified by practice type, and a scoring scale was developed. Principal component analysis (PCA) was used to reduce data on all constructs that made up each variable. All three groups showed adequate knowledge and a positive attitude towards use, apart from medical students who were not as keen to support future use in their own practice. Although medical pra ctitioners supported the use of this technology, with necessary guidelines, expertise and affordability, only 18% from private practice reported having used it. PCA reduced data to fewer parsimonious constructs for all 3 groups: common threads included an awareness that genetic testing may improve h ealth and disease outcomes; guidelines for use; and the provision of education to increase awareness, training to bolster expertise and confidence to use these services. Participants in this study attributed a lack of uptake to limited expertise and professional support, and a lack of legislative gu idelines. We recom...
