With RARP supplanting laparoscopic radical prostatectomy (LRP) as the primary MIRP technique, there is cause to reexamine these findings. METHODS As of October 1, 2008, a robot-assisted modifier code was introduced to recognize robotic-assisted procedures approved by the U.S. Food and Drug Administration. Relying on the Nationwide Inpatient Sample between October 2008 and December 2009, patients with a primary diagnosis of prostate cancer treated with RP were identified (n=19462), for a weighted national estimate of 97388 cases. The robot-assisted modifier (ICD-9-CM 17.4x) code was used to identify RARP. Patients with the minimally invasive modifier code (ICD-9-CM 54.21) were classified as having undergone laparoscopic RP, and were removed from further analyses (n=184). The remainder of patients, with an absence of RARP or LRP codes, was determined as having undergone an ORP. Propensity-matched analysis was used to account for underlying differences in RARP and ORP cohorts. Subsequently, we compared the rates of blood transfusions, intraoperative and postoperative complications, prolonged length of stay (pLOS) beyond the 75th percentile of two days, as well as in-hospital mortality. RESULTS Of a weighted sample of 97388 RP, 61.1% were RARP, 38.0% were ORP and 0.9% were LRP. Following propensity-score matching, for RARP and ORP respectively, blood transfusion rates were 2.2 vs. 7.7% (p<0.001); intraoperative complications were 0.4 vs. 1.0% (p<0.001); postoperative complications were 9.1 vs. 11.1% (p<0.001); pLOS rates were 14.0 vs. 39.2% (p<0.001); and in-hospital mortality was 0.0 vs. 0.1% (p=0.037). CONCLUSIONS The current study represents the first objective assessment showing that RARP has supplanted ORP as the most common surgical approach for RP. Moreover, we demonstrate superior adjusted perioperative outcomes after RARP in virtually all of the examined outcomes relative to ORP. These results provide additional evidence to the ongoing RARP vs. ORP debate. In the absence of a randomized trial, existing population-based studies provide the highest level of clinical evidence in the comparison of RARP vs. ORP. © 2012 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 187Issue 4SApril 2012Page: e542-e543 Advertisement Copyright & Permissions© 2012 by American Urological Association Education and Research, Inc.MetricsAuthor Information Quoc-Dien Trinh Detroit, MI More articles by this author Maxine Sun Montreal, Canada More articles by this author Jesse D.

Full frame machine prediction
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.
