The value of surgical experience: excess costs associated with the Roux-en-Y gastric bypass learning curve.
Article in Surgical endoscopy, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGastric bypass has a steep learning curve that is associated with increased adverse outcomes and these adverse outcomes are associated with increases in cost. This study sought to quantify the effect of cumulative procedure volume on inpatient cost and characterize the excess cost associated with a surgeon's learning curve.
methodsThis was a retrospective study of 29 high-volume surgeons during the first 6 years of performing gastric bypass in a regionalized center of excellence system. Cumulative volume was determined using the procedure date and analyzed in blocks of 25 cases. The main outcomes of interest were inpatient cost for the initial hospital stay in 2014 Canadian dollars as well as prolonged length of stay (≥ 3 days).
resultsOverall, 11,684 cases were identified from April 2009 to March 2015. After a surgeon's 50th case, the adjusted inpatient cost decreased by $2775 (95% CI $- 4352 to $- 1204 p = 0.001) compared to the first 25 cases. Cost savings were maintained through a surgeon's 400th case. The average cost savings after the 50th case was $2082 (95% CI $- 3194 to $- 962 p < 0.001) and the excess cost attributable to the first 50 cases was $104,077 (95% CI 48,104 to 159,682) per surgeon. Surgeon experience was also associated with a decrease odds of prolonged length of stay.
conclusionsThis study demonstrated the influence of surgeon experience on improved cost efficiencies. We also characterized that the average excess cost per surgeon of implementing gastric bypass was approximately $104,000. This is relevant to future health system planning as well as providing an economic incentive for impactful training interventions.
