Furthermore, single surgeon series have suggested improved patient outcomes using robotic technology. However, the interaction of surgeon volume and surgical approach on post-operative morbidity has been less well characterized. The objective of this study is to assess the impact of surgeon volume and surgical approach on post-RP morbidity. METHODS The Maryland Health Service Cost Review Commission (HSCRC) database was queried for men undergoing RRP or RALRP from the fourth calendar quarter of 2008 to the first calendar quarter of 2011 using discharge ICD-9 codes. Patient demographic and immediate post-operative outcomes including length of hospital stay (LOS), hospital re-admission within 30 days, and need for intensive care unit admission were compared between patients undergoing surgery by high volume (>40 cases/year) and low volume surgeons (< 40 cases/year). Multivariable logistic regression analyses were performed to test the association between operative approach and surgeon volume with post-operative outcomes. RESULTS The study cohort consisted of 4,064 men undergoing radical prostatectomy of whom 76.6% had their surgery performed by a high volume surgeon. Patients undergoing RP by a low volume surgeon were more likely to have a robotic operation, be of non-Caucasian ethnicity, have a longer LOS (2.1 vs. 1.7 days, p <0.001), and were more likely to be readmitted to the hospital within 30 days (1.8% vs. 0.13%, p < 0.001). Multivariable logistic regression analyses demonstrated that high surgeon volume was significantly associated with lower risk of LOS > 2 days (OR 0.3, 95% CI: 0.2 - 0.4). Furthermore, open RP was significantly associated with LOS > 2 days (OR 2.3, 95% CI: 1.8 - 3.0) and 30-day readmission (OR 20.6, 95% CI: 2.7 - 154.5). After controlling for surgical approach, high surgeon volume was significantly associated with LOS > 2 days for both robotic and open RP, but the impact of surgeon volume on LOS was significantly greater for open RP. CONCLUSIONS Patients undergoing Robotic RP experienced shorter hospital stays and decreased rates of 30 day re-admission compared to those undergoing open RP. However, surgeon volume decreases post-operative LOS regardless of approach. When considering state-wide data, high surgeon volume and a robotic surgery improve post-operative morbidity. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e206 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Jeffrey Mullins Baltimore, MD More articles by this author Elias Hyams Baltimore, MD More articles by this author Phillip Pierorazio Baltimore, MD More articles by this author Zhaoyong Feng Baltimore, MD More articles by this author Bruce Trock Baltimore, MD More articles by this author Mohamad Allaf Baltimore, MD More articles by this author Brian Matlaga Baltimore, MD More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...

Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
