Abstract
PURPOSE
Primary prophylactic granulocyte colony-stimulating factors (PP-CSFs) are prescribed alongside chemotherapy regimens that carry a significant risk of febrile neutropenia (FN). As part of S1415CD, a prospective, pragmatic trial evaluating the impact of automated orders to improve PP-CSF prescribing, we evaluated patients' baseline knowledge of PP-CSF and whether that knowledge improved following the first cycle of chemotherapy.
METHODS
Adult patients with breast, colorectal, or non-small-cell lung cancer initiating chemotherapy were enrolled in S1415CD between January 2016 and April 2020. Eight questions assessing knowledge of CSF indications, risks, benefits, and out-of-pocket costs were included in a baseline survey and in a follow-up survey at the end of the first cycle of chemotherapy. Responses were stratified by the trial arm and whether chemotherapy was low, intermediate, or high FN risk.
RESULTS
Of the 3605 eligible patients, 3580 (99.3%) completed the baseline survey, and 3420 (95.5%) completed the follow-up survey. At baseline, 803 (22.4%) patients responded "Don't know" to all 8 questions, and all patients averaged 2.75 correct questions. At follow-up, knowledge increased by 0.34 in the high-FN-risk group (p < 0.001) but declined for the other FN-risk groups. In multivariate analysis, receiving a high-FN-risk regimen and younger age were significantly associated with knowledge improvement.
CONCLUSION
Chemotherapy patients had poor knowledge of PP-CSF that improved only modestly among recipients of high-FN-risk chemotherapy. Further efforts to inform patients about the risks, benefits, and costs of PP-CSF may be warranted, particularly for those in whom prophylaxis is indicated.
