Cross-sectional survey of cognitive status and attitude of different population about biobanking donation

Abstract

Objective To understand the cognition and attitude of patients, medical staff and medical examination people on biobanks and their willingness to donation. Methods A cross-sectional study was conducted among 452 individuals, including patients, medical staff and people receiving health checkup at a hospital in Beijing from July to September, 2017.The questionnaire assessed the respondents′ demographic data, general knowledge about biobanking and the factors influencing their willingness to donate specimens to biobanks.Pearson′s Chi-square test, student t test or ANOVA were used for univariate analysis.Additionally, the linear regression analysis and logistic regression analysis were used for multivariate analyses. Results A total of 452 questionnaires were delivered, and the effective questionnaires amounted to 440, including 196 medical staff, 123 patients and 121 health checkup individuals.The awareness score of biobanks was significantly different among the medical staff, patients and health checkup individuals(P<0.05). After adjustment for potential risk factors, we found that the population characteristics and the experience of participation in a medical research were the independent beneficial factors of the awareness score.The percentage of the willingness of donation in medical staff, health checkup individuals and patients were 83.7%, 76.9% and 70.7%, respectively.The results of univariate analyses suggested that the population characteristics, education level, health conditions, the history of blood donation, and the experience of participation in a medical research were significantly associated with the willingness to donate(all P<0.05). Population characteristics and health conditions were independently relevant to the willingness of donation, after multivariate analyses of logistic regression. Conclusions Despite the strong willingness to donate biospecimens, patients and health checkup individuals lack knowledge of biobanking. It is apparent that we need to strengthen promotions and to encourage the ethics and humanities to improve the knowledge of biosample donation, for healthy development of hospital-based biobanks.
