Informed lay preferences for delivery of racially varied pharmacogenomics.

Abstract

To understand public perceptions and opinions of three options for prescribing medicine: individualized genetic testing, race-based prescription, and traditional prescription. Focus groups in urban, suburban, and rural communities over-sampled for minority groups conducted from February through April, 2001 in Georgia. Group members (N = 102) identified individualized genetic testing as providing the best quality of care (60% of talk turns; 75% in postdiscussion anonymous survey), but stipulated the need for protection from the invasion of privacy, discrimination, and prohibitive cost. Most individuals chose genetic testing because it provided individualized attention, and African-Americans indicated they would choose genetic testing even if the costs were high. Overall, individuals were suspicious of race-based prescription. Analyses for degree of suspicion revealed a main effect for race and an interaction effect for race and gender. If issues of cost, discrimination, and privacy are addressed, lay individuals prefer genetic testing as the basis for prescription of medicines that exhibit racially patterned response variation.
