Attitudes and perceptions of patients towards methods of establishing a DNA biobank

Background This study aimed to assess patient attitudes as part of the planning process for a large-scale effort to collect genetic samples for research from excess clinical blood specimens (‘DNA Databank’ project). Method A pre-tested, 38-item questionnaire was mailed to a random sample of 5,000 inpatients, outpatients, and emergency department patients. Results Approximately 20% of patients responded (n = 1003). Most were comfortable with anonymized genetic information being used for research (89.3%) and supported the potential benefits (98.7%). A binary logistic regression on the level of comfort with the DNA program shows that the variability in respondents’ feelings about the program can best be explained by beliefs, age, and health status. Respondents were attitudinally segmented into 5 distinct categories. Conclusions These data indicate general acceptance among respondents, but a subset of the population would be opposed to the program. This reinforces the need to broadly and continuously communicate with patients about the program and the ability to exclude a given sample. The effects of prior beliefs would benefit from further exploration.
