Association of surgeon case numbers of pancreaticoduodenectomies vs related procedures with patient outcomes to inform volume-based credentialing.
The purpose of this study was to evaluate whether surgeon experience with related procedures was associated with better outcomes for pancreaticoduodenectomy compared with procedure-specific experience alone. In this proof-of-concept cohort study, few surgeons met even modest annual volume thresholds for pancreaticoduodenectomy. The investigators indicated that inclusion of related procedure volumes may safely expand the cohort of surgeons credentialed to perform certain procedures under volume-based standards.

Surgeon leadership style and risk-adjusted patient outcomes.
The goal of this study was to determine if individual surgeons' personality traits and related leadership behaviors – such as participation in continuing education, effective self-reflection, and openness to feedback – correlated with patient-level outcomes after bariatric surgery. Surgeons from the Michigan Bariatric Surgery Collaborative (MBSC) were administered the Life Styles Inventory (LSI) assessment, the results of which were then collapsed into three styles corresponding with particular patterns of individual thinking and behavior: constructive, passive/defensive, and aggressive/defensive. Patient-level risk-adjusted rates of complications after bariatric surgery were then used to quantify the impact surgeon style had on post-operative outcomes. The results of the study demonstrate that surgeons' leadership styles are correlated with surgical outcomes for their individual patients.

Effect of surgeon age on bariatric surgery outcomes.
This study examined the effect of surgeon age on complication rates for bariatric surgery. A retrospective study was done with 71 surgeons in Michigan who participated in a statewide collaborative improvement program. Older surgeons performed more Roux-en Y Gastric Bypass (40%) and less sleeve gastrectomy (38.8%) than younger surgeons. There was not found to be any statistically significant differences in patient outcome between the two age groups.
