Informed consent for bone marrow transplantation: identification of relevant information by referring physicians.
Two hundred Michigan hematologists-oncologists were sent a 34-item questionnaire designed to assess what patients should know at the time of giving consent to bone marrow transplant (BMT). Sixty-three (32%) responded to a single mailing and rated items on a 8-point scale, varying from 0 = no need to know to 7 = appreciation of consequences essential. The mean rating across items was 5.2, indicating that all items were important. Statistically, the items separated into three groups: (1) above average importance - 13 items; (2) average importance - 9 items; (3) below average importance - 12 items. Items of above average importance included the rationale for BMT and the collective risks and benefits of the process, including the patient's well-being post-transplant. Informed consent documents did not include 5/13 items of above average importance, yet 12/21 items of average and below average importance were included. Fourteen demographic variables were correlated with each item and none were significant, indicating that the ratings represent a broad consensus in the referring physician community as to what a patient should understand before consenting to BMT. The vast majority of referring physicians agreed that patients usually have an adequate understanding of BMT at the time of giving informed consent and that a fully informed patient is more likely to adhere to the treatment regimen.
