Multicenter Study Observational Study
Local Recurrence and Breast Oncological Surgery in Young Women With Breast Cancer: The POSH Observational Cohort Study.
To assess clinical and surgical factors affecting local recurrence and survival in young breast cancer patients in the Prospective study of Outcomes in Sporadic versus Hereditary breast cancer (POSH). ⋯ Surgical extent appears less important for DDFI than completeness of excision or, where appropriate, chest-wall radiotherapy. Despite higher local-recurrence rates for BCS, surgical type does not influence DDFI or OS after adjusting for known prognostic factors in young breast cancer patients.

To evaluate the association of trauma center volume change over time with mortality. ⋯ Increasing volume was associated with improving outcomes, whereas decreasing volume was associated with worsening outcomes. High-level trauma center infrastructure seems to facilitate the volume-outcome relationship. The trauma center designation process should consider volume changes in the overall system.

To examine the extent to which multiple, sequential complications impacts variation in institutional postoperative mortality rates. ⋯ FTR occurs predominantly among patients who have more than 1 complication with a dose-response relationship as complications accrue. As this dose-response relationship is observed across hospitals, surgical quality improvement efforts may benefit by shifting focus to broader interventions designed to prevent subsequent complications at all hospitals.

Following calls from the National Institutes of Health and American College of Surgeons for "urgently needed" research, the objectives of the present study were to (1) ascertain whether differences in 30/90/180-day mortality, major morbidity, and unplanned readmissions exist among adult (18-64 yr) and older adult (≥65 yr) emergency general surgery (EGS) patients; (2) vary by diagnostic category; and (3) are explained by variations in insurance, income, teaching status, hospital EGS volume, and a hospital's proportion of minority patients. ⋯ Racial/ethnic disparities exist in longer-term outcomes of EGS patients and are, in part, determined by differences in factors associated with emergency care. Efforts such as these are needed to understand the interplay of influences-both in-hospital and during the equally critical, postacute phase-that underlie disparities' occurrence among surgical patients.
