Abstract

Background Partially presented in poster format at the 40th and 41st Annual Meetings of the American Society of Clinical Oncology, held in 2004 in New Orleans, Louisiana and in 2005 in Orlando, Florida. Purpose We aimed to: (a) assess patient knowledge about cancer clinical trials (CCT) and satisfaction with their decision to participate, (b) determine whether satisfaction correlates with objective understanding, or other factors, and (c) identify correlates of increased understanding. Methods A convenience sample of 100 patients were recruited. Instruments assessed quality of informed consent (QuIC), quality of life (EORTC QLQ C-30), anxiety and depression (HADS), and preferences for information and involvement in decision making. Measures were completed within 2 weeks of clinical trial enrollment. Results One hundred two patients (68 male) with a median age of 58.4 years (29-85) were registered in 27 of the 33 therapeutic cancer clinical trials approved for the Consent Study. Mean QuIC objective knowledge (QuIC-A) was 77.6 (/100) (95% CI, 75.7-79.4) and perceived (subjective) understanding (QuIC-B) 91.5 (95% CI, 89.6-93.3). There was low but significant correlation between QuIC-A and B (R = 0.26, p = 0.008). Satisfaction was very high. Correlation between QuIC-B and satisfaction was moderate (0.430, p Conclusions Patient knowledge regarding CCT is similar to published US data, and satisfaction is high. Satisfaction correlates with perceived but not objective understanding o…

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many participants, including biobank participants, do not understand the information disclosed to them.

    “and, not surprisingly, many participants do not understand the information disclosed (4–6,70,71, 83, 87, 97), including biobank participants (93,104,114).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
