Abstract
In order to document patients' views on residual blood use for research purposes, a questionnaire survey was conducted at Aichi Cancer Center Hospital in October 1997. Subjects were patients who had undergone blood tests at a central blood sampling room in the morning during the week of the study enrollment. The questionnaire was handed out and collected at a waiting area in front of the blood sampling room. Of the 583 patients to whom we tried to hand out the questionnaire, 558 participated (258 males, 294 females, and 6 of sex unknown) and 25 refused. Those who regarded research to improve health care as important were 76.7% of those sampled. Only 28 patients (5.0%) answered that they would not permit the use of their residual blood for research purposes. Although logistic analysis did not detect significant factors influencing the giving of permission, the percentage who would not permit the use of their residual blood for research purposes was significantly higher in cancer outpatients (6.7%) than in inpatients (1.0%). It seems desirable for hospitals to establish an open policy concerning residual blood use for research purposes.
