Abstract

fetched live from OpenAlex

BACKGROUND: Local anesthesia has shown to be safe and cost-effective for elective hand surgery procedures performed outside of the operating room. The economic benefits of local anesthesia compared to regional anesthesia for hand surgeries performed in the operating room involving repair of tendons, nerves, arteries, or bones are unclear. This study aimed to compare costs pertinent to hand surgeries performed in the main operating room under local anesthesia (LA) or brachial plexus (BP) block. METHODS: We performed a cross-sectional study on the first 70 randomized patients from a prospective controlled trial of anesthesia modalities for hand surgery. The primary objective was to determine the mean anesthesia-related cost, and the secondary objectives were to analyze block performance time, block onset time, duration of anesthesia, duration of surgery, and time in the recovery room. RESULTS: The mean anesthesia-related cost of performing hand surgery under LA as a wrist and/or digital block was $236 ± 30, compared to $435 ± 43 for BP, a difference of $199 per case. The mean block performance time was shorter for LA (1.3 minutes) versus BP (7.0 minutes). The mean anesthesia-related time was longer in BP (30.7 ± 16 minutes) compared to LA (17.7 ± 6.7 minutes), and consequently the total anesthesia time was longer in BP. CONCLUSIONS: We demonstrated that local anesthesia compared to brachial plexus block achieved substantial cost savings in complex hand surgeries by decreasing major expenses. In an era of cost-consciousness, the use of LA represents an important modality for health systems to optimize patient flow and increase cost-effectiveness.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
