Biobanks for aging research - perceptions and choices among rheumatology outpatients.

Abstract

Objective: Biobanks for research (BBR) have enormous value for research, including those specifically oriented to chronic diseases. Knowing public attitudes and perceptions is key to design and implement patient-centered BBR. We assessed patient awareness, perception and choices among rheumatology outpatients regarding aging biobanking activities.

Methods: We conducted a cross-sectional survey of patients, aged 50 or older, attending an outpatient rheumatology tertiary department. Demographic data and perceptions about biobanking were collected and statistical analysis was performed.

Results: 132 valid questionnaires were obtained (mean age: 63,4; 68,2% female; mean education years: 8,35). 61,7% of respondents did not know the specific term "biobank", 57,7% knew they could donate biological material for BBR, 89,9% agreed with these infrastructures and 88,3% would consider participation Those participants with more years of education were more knowledgeable and prone to biobank participation. Willingness to participate in BBR was mainly related (86,4%) to the advancement of scientific knowledge and not individual gain. Scientific research institutes were indicated as the most adequate institutions to manage BBR. Informed consent, anonymity and confidentiality ranked as top requisites for biobank participation. 61,3% of respondents expressed their agreement with aging biobanks, considering these as a sign of respect for specific problems of people of older ages such as higher disease burdens.

Conclusion: Knowledge of biobanks was found to be limited. Participants were positive toward the setting up of biobanks in general and patient-centered aging biobanks in particular. Knowledge about biobanks and acceptance were higher among participants with higher education years.
