Patient-Reported Outcomes and Experiences with Population Genetic Testing Offered Through a Primary Care Network.

To explore patient experiences in a large-scale primary care-based, preemptive genetic testing program. Patients who received genetic results from the initiative were invited to participate in an online survey 3 weeks postresult disclosure. A 6-month follow-up survey was sent to assess changes over time. The initial survey was completed by 1646 patients, with 544 completing the 6-month follow-up survey. The following outcomes were high overall: patient-reported understanding of results (cancer: 87%; cardiac: 86%); perceived utility (75%); positive emotions (relieved: 66.8%; happy: 62.0%); family result sharing (67.6%); and satisfaction (87%), although analysis by demographic factors identified groups who may benefit from additional education and emotional support. Results-related health behaviors and discussions with providers increased over time (screening procedures 6.1% to 14.2%  < 0.001; provider discussion 10.3% to 25.3%,  < 0.001), and were more likely to take place for patients with positive cancer and/or cardiac results (39.8% vs. 7.6%,  < 0.001). Forty-seven percent of patients reported insurance discrimination concerns, and most (79.4%) were not familiar with privacy and nondiscrimination laws. Concerns regarding discrimination and negative emotions decreased between the two survey time points (privacy issues 44.6% to 35.1%  < 0.001; life insurance discrimination concerns 35.5% to 29.6%,  = 0.001; anxiety 8.1% to 3.3%,  < 0.001; and uncertainty 19.8% to 12.8%,  < 0.001). These findings led to the development and integration of additional patient resources to improve program implementation. Our findings highlight patient experiences with and areas of need in a community-based genomic screening pilot initiative using a mixed primary care/genetics provider model to deliver precision medicine.
