Examining Knowledge and Information Seeking Behaviors towards Blood Transfusion Among Individuals with Cancer

Examine knowledge and information seeking behaviors towards blood transfusions among individuals with metastatic or recurrent cancer.

An online survey was conducted from a nationally representative patient panel in 1Q2011. All respondents were ≥18 years and diagnosed with cancer by a physician. Participants were asked about their blood transfusion history, information seeking behaviors, and knowledge about blood transfusion.

206 individuals responded to survey. 65% (n=133) were female and 25% (n=52) were over 55 years. 55% (n=114) were anemic and 45% (n=92) not anemic. 62% (n=128) had received blood transfusion, whereas, 38% (n=78) had no transfusions. Top two sources of information are doctor (85%) and Internet (78%). Among those previously transfused, 74% received right amount of information, whereas, 11% received too little information, and 15% received too much information. More than 90% of transfused indicated they knew the reasons for and benefits of getting a blood transfusion. Less than two-thirds received information about the costs. Over 65% of not transfused said that it is extremely important to know risks of infections, right blood type and screening techniques. Among previously transfused, about 70% agreed that they made an informed choice about receiving blood transfusions. Among the previously transfused, 78% agree that they knew the benefits compared with 68% not transfused. About 68% of transfused and not transfused agree they knew the risks of blood transfusion.

Doctor's office and internet are primary sources of information about blood transfusions. Gaps in knowledge exist about benefits, risks, and costs of blood transfusions. A significant number feel that they need more information about blood transfusion to make an informed choice. Providers should consider adopting shared-decision making with their patients.
