Attitudes Toward Use of an APOL1 Genetic Testing Chatbot in Living Kidney Donor Evaluation: A Focus Group Study

Living kidney donor (LKD) candidates of African ancestry are increasingly asked to undergo Apolipoprotein L1 (APOL1) genetic testing during the donor evaluation process to better understand their risk of kidney disease. LKD candidates' attitudes about using a clinical chatbot on APOL1 remain unknown. This study builds on prior work to culturally adapt the Gia (Genetic Information Assistant) chatbot on APOL1 by assessing donor, recipient, and community member attitudes about the Gia chatbot for enhancing the integration of APOL1 testing into the LKD clinical evaluation workflow.

This study involved focus groups and a post-focus group survey in two US cities about the APOL1 Gia chatbot. Qualitative data were analyzed via thematic analysis, and descriptive statistics were used for demographic data.

We conducted 10 focus groups including 54 participants (25 LKDs, 23 community members, and 6 living donor kidney transplant recipients of African ancestry). Five themes emerged: (1) participants supported LKD candidates using the Gia chatbot before the nephrologist clinic visit, (2) participants were interested in undergoing APOL1 testing after using Gia, (3) APOL1 testing costs may influence LKD candidates' willingness to get tested, (4) patients of African ancestry may hold varying preferences for using chatbots in the healthcare setting, and (5) individual-level barriers may limit the use of Gia in the healthcare setting.

Individuals of African ancestry were highly receptive to integrating the APOL1 chatbot into LKD candidate clinical evaluation, which bodes well for integrating chatbots into the APOL1 clinical genetic testing process.
