Recommendations for application and interpretation of the Blood Donor Satisfaction Questionnaire (BDSQ)

ABSTRACT

ABSTRACT Background: The level of satisfaction of donors with the blood donation system is an important factor which influences their intent to return for future donation. A 25-item questionnaire on the satisfaction of blood donors has been recently proposed to assess the donor satisfaction with the service provided by a blood bank. The objective of this study was to present a proposal for application and interpretation of a BDSQ considering a sample of blood donors of a Brazilian blood bank. Methods: A sample of 1019 blood donors at the Regional Hemotherapy Center of Franca, Brazil, answered the BDSQ. A top-box analysis was used to assess the associations between the variables characterizing the profiles of blood donors and their overall satisfaction with the service provided by the blood bank. We proposed the use of a performance-importance plot (PIP) for the interpretation of the 25 items of the BDSQ. Results: Older donors are more likely to report lower overall satisfaction with the service provided by the blood bank. PIP allows us to classify the items of BDSQ into longand short-term improvement opportunities as well as into motivational and hygiene factors. Motivational factors (i.e. attributes that promote overall satisfaction when present) tend to be associated with the treatment offered by the blood bank staff. Donors seem to give more importance to the interpersonal aspects than to the physical structure of the service and other aspects of convenience. Conclusions: Top-box analysis and PIP proved to be efficient strategies to interpret the results of the BDSQ.
