Early discharge after core liver biopsy: is it safe and cost-effective?
Bibliographic record
Abstract
OBJECTIVE: To determine if ambulatory patients who have undergone image-guided core liver biopsy with an 18-gauge needle and spring-loaded biopsy gun can be safely discharged after 1 hour of observation in the radiology department. METHODS: Fifty-four consecutive patients underwent ultrasound-guided core liver biopsy for a variety of suspected diffuse liver diseases. Post-biopsy, they were asked to grade their pain on a scale of 1-10 after 1 hour of recumbency on a hospital gurney in the department. At 2 weeks, all patients were contacted and asked about their level of pain and when they returned to normal activities. RESULTS: Of the 54 patients enrolled, 4 were lost to follow-up. Pain was the most common minor complication, occurring in 31 (62%) of patients. The average level of pain after 1 hour was 2.1 (1 = no pain) and after 24 hours, 1.5. Seven patients were admitted to a medical daycare bed for a total of 4 hours and were then discharged. The remainder were discharged after 1 hour. Forty (80%) patients were pain-free after 24 hours, 36 (90%) of the 40 patients who were working returned to work the following day, and within a week, all patients had returned to all normal activities. No patients required an inpatient hospital stay or sought assistance at an emergency department. CONCLUSION: These preliminary results demonstrate that ultrasound-guided 18-gauge liver core biopsy is a safe procedure, and, provided larger series confirm these findings, patients showing no complications can be discharged from the department after 1 hour with notable cost savings.

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.
