Participatory Genomic Testing Can Effectively Disseminate Cardiovascular Pharmacogenomics Concepts within Federally Qualified Health Centers: A Feasibility Study

Abstract

Objective: We assessed feasibility of an educational program designed to enhance stakeholder knowledge and perceptions of pharmacogenomics at a federally qualified health center (FQHC).

Design: FQHCs have a rich history of providing care to the underserved, but often are not represented by studies evaluating cutting-edge concepts. We used a novel educational platform to provide participatory genomic testing and classroom education. We assessed participant knowledge and perceptions using questionnaires between May and July 2018.

Setting: We partnered with a FQHC affiliated with an academic medical center in Chicago.

Participants: Using convenience sampling, we recruited 20 providers and 10 community members for a feasibility study. Providers included physicians, physician extenders, community health workers, and patient health navigators. Community members were patients, supporters, and/or FQHC advisory board members.

Intervention: Participants had the option to undergo personal genomic testing. Online educational modules included basic genetics, cardiovascular pharmacogenomics, and personalized medicine. Education concluded in a 2-hour live course with case-based discussions.

Main outcome measures: Our main outcome was testing pilot feasibility. Baseline knowledge and perceptions were compared with post-intervention assessments using descriptive statistics, t tests (or Wilcoxon rank-sum) for continuous variables and chi-squared (or Fisher's exact) for categorical variables.

Results: We found that attitudes toward the intervention were positive and remained so after intervention. Our intervention was both feasible and acceptable. Genomics knowledge increased for nearly all participants.

Conclusions: We have determined that a pharmacogenomics educational program tailored for an underrepresented community is feasible and acceptable. Outcomes will advise methodology for larger implementation studies.
