The Cancer and Leukemia Group B (CALGB) 9343 trial demonstrated that adjuvant radiation therapy (RT) can be omitted in women aged 70 years or older, with small, estrogen receptor (ER)+ breast cancer. We postulated that RT usage after CALGB's publication should have decreased over time. ⋯ The CALGB trial had a minimal impact on the rate of adjuvant RT use among elderly women with small, hormone positive breast cancers. Significant variation in RT usage exists across sociodemographic strata.

There are different views on the effects of resident involvement on surgical outcomes. We hypothesized that resident participation in surgical care does not appreciably alter outcomes. ⋯ We found substantial improvement in FTR with resident involvement, both in unmatched and propensity-matched comparisons. Senior-level resident participation seemed to attenuate, and even improve, surgical outcomes, despite slightly increased resource use. These results provide some reassurance about teaching paradigms.

The rate and consequences of reoperation after liver transplantation (LT) are unknown in the United States. ⋯ This is the first national study reporting that nearly one-third of transplant recipients undergo reoperation within 90 days of LT. Although necessary at times, reoperation is associated with increased risk of death at 1 year; however, it appears that the timing of these interventions can be critical, due to the type of intervention required. Early reoperative intervention does not appear to influence long-term outcomes, and delayed intervention (after 30 days) is strongly associated with decreased survival.

Time-sensitive, critical surgical illnesses require care at specialized centers. Trauma systems facilitate patient transport to designated trauma centers, but formal systems for nontraumatic critical illness do not exist. We created the critical care resuscitation unit to expedite transfers of adult critically ill patients with time-sensitive conditions to a quaternary academic medical center, hypothesizing that this would decrease time to transfer, increase transfer volume, and improve outcomes. ⋯ The critical care resuscitation unit dramatically increased the volume of critically ill surgical patients. It decreased transfer times, increased volume, and, for those who required urgent operation, decreased time from initial referral to operating room. This benefit seems to be most marked in patients needing urgent operation. This might be a paradigm shift expediting the transfer of patients with time-sensitive critical illness to an appropriately resourced specialty center.

Colorectal surgical site infections (C-SSIs) are a major source of postoperative morbidity. Institutional C-SSI rates are modeled and scrutinized, and there is increasing movement in the direction of public reporting. External validation of C-SSI risk prediction models is lacking. Factors governing C-SSI occurrence are complicated and multifactorial. We hypothesized that existing C-SSI prediction models have limited ability to accurately predict C-SSI in independent data. ⋯ Published C-SSI risk prediction models do not accurately predict C-SSI in our independent institutional dataset. Application of externally developed prediction models to any individual practice must be validated or modified to account for institution and case-mix specific factors. This questions the validity of using externally or nationally developed models for "expected" outcomes and interhospital comparisons.
