Implementation of a culturally competent APOL1 genetic testing programme into living donor evaluation: A two-site, non-randomised, pre-post trial design

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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Advancing Genetic Testing in Kidney Diseases: Report From a National Kidney Foundation Working Group

About 37 million people in the United States have chronic kidney disease, a disease that encompasses multiple causes. About 10% or more of kidney diseases in adults and as many as 70% of selected chronic kidney diseases in children are expected to be explained by genetic causes. Despite the advances in genetic testing and an increasing understanding of the genetic bases of certain kidney diseases, genetic testing in nephrology lags behind other medical fields. More understanding of the benefits and logistics of genetic testing is needed to advance the implementation of genetic testing in chronic kidney diseases. Accordingly, the National Kidney Foundation convened a Working Group of experts with diverse expertise in genetics, nephrology, and allied fields to develop recommendations for genetic testing for monogenic disorders and to identify genetic risk factors for oligogenic and polygenic causes of kidney diseases. Algorithms for clinical decision making on genetic testing and a road map for advancing genetic testing in kidney diseases were generated. An important aspect of this initiative was the use of a modified Delphi process to reach group consensus on the recommendations. The recommendations and resources described herein provide support to nephrologists and allied health professionals to advance the use of genetic testing for diagnosis and screening of kidney diseases.

Strategies for choosing the best living donor: A review of the literature and a proposal of a decision-making paradigm

Transplantation remains the gold-standard treatment for pediatric end-stage kidney disease. While living donor transplant is the preferred option for most pediatric patients, it is not the right choice for all. For those who have the option to choose between deceased donor and living donor transplantation, or from among multiple potential living donors, the transplant clinician must weigh multiple dynamic factors to identify the most optimal donor. This review will cover the key considerations when choosing between potential living donors and will propose a decision-making algorithm.

Development of a culturally targeted chatbot to inform living kidney donor candidates of African ancestry about APOL1 genetic testing: a mixed methods study

Clinical chatbots are increasingly used to help integrate genetic testing into clinical contexts, but no chatbot exists for Apolipoprotein L1 (APOL1) genetic testing of living kidney donor (LKD) candidates of African ancestry. Our study aimed to culturally adapt and assess perceptions of the Gia® chatbot to help integrate APOL1 testing into LKD evaluation. Ten focus groups and post-focus group surveys were conducted with 54 LKDs, community members, and kidney transplant recipients of African ancestry. Data were analyzed through thematic analysis and descriptive statistics. Key themes about making Gia culturally targeted included ensuring: (1) transparency by providing Black LKDs' testimonials, explaining patient privacy and confidentiality protections, and explaining how genetic testing can help LKD evaluation; (2) content is informative by educating Black LKDs about APOL1 testing instead of aiming to convince them to undergo testing, presenting statistics, and describing how genetic discrimination is legally prevented; and (3) content avoids stigma about living donation in the Black community. Most agreed Gia was neutral and unbiased (82%), trustworthy (82%), and words, phrases, and expressions were familiar to the intended audience (85%). Our culturally adapted APOL1 Gia chatbot was well regarded. Future research should assess how this chatbot could supplement provider discussion prior to genetic testing to scale APOL1 counseling and testing for LKD candidate clinical evaluation.
