Abstract
e18762 Background: Febrile neutropenia is a serious complication of chemotherapy leading to hospitalization in cancer patients. According to a practice guidelines published by ASCO (American Society of clinical Oncology) and IDSA (Infectious Diseases Society of American) in 2018, patients meeting the criteria for low-risk neutropenia according to the MASCC score (Multinational Association for Supportive Care in Cancer Score) could be treated as outpatient and thus avoid hospitalization. The objective of the study was to assess the number and proportion of patients who were hospitalized for febrile neutropenia in university hospital that would have met the low risk criteria of febrile neutropenia. We also wanted to know if these patients had experienced a favorable outcome during hospitalization. Methods: We performed a retrospective study including all patients admitted for febrile neutropenia in 3 hospitals in Quebec City during the period from January 1, 2018 to December 31, 2019. We excluded patients with leukemia, as well as stem cell transplant patients. The chart review retrospectively established the MASCC score for each patient. We also established according to predefined criteria whether the clinical course was favorable or unfavorable. Results: A total of 177 hospitalizations met our inclusion criteria. We found that 101/177 (57.1%) of hospitalized patients met the criteria for low-risk neutropenia according to the MASCC score (score of 21 and above). Of this number 74/177 (41.8%) presented all the criteria suggested for receiving outpatient treatment. In these patients 70/177 (39.5%) presented a favorable evolution during hospitalization and thus 4/177 (2.3%) presented an unfavorable evolution. Among these, 2 patients presented with infections considered major (2 bacteremia), 1 patient developed acute renal failure, and 1 other patient developed delirium. There was no death or admission to the intensive care unit in these 4 patients. Conclusions: According to this retrospective study, about 40% of patients admitted for febrile neutropenia filled the criteria of low risk febrile neutropenia and could be treated as outpatient. Given this represents a significant proportion of patients, a protocol for systematic follow-up of outpatient treatment with low-risk febrile neutropenia should be put in place.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
