Importance: Accredited breast centers in the United States are measured on performance of breast conservation surgery (BCS) in the majority of women with early-stage breast cancer. Prior research in regional and limited national cohorts suggests a recent shift toward increasing performance of mastectomy in patients eligible for BCS.
Objective: To examine whether mastectomy rates in patients eligible for BCS are increasing over time nationwide, and are associated with coincident increases in breast reconstruction and bilateral mastectomy for unilateral disease.
Introduction: Management of choledocholithiasis and its complications is variable and often requires transfer to a specialty facility. This study links patient-specific characteristics with the outcome measure of complicated choledocholithiasis to identify high-risk patients who may require expedited treatment or transfer to a higher level of care.
Materials And Methods: Patients with a discharge diagnosis of choledocholithiasis (CDL) were identified from the 2009 Nationwide Inpatient Sample (NIS).
Biliary obstruction discovered during cholecystectomy remains a challenging problem. To determine the best management, this retrospective study compared intervention during the same admission (SA) versus delayed/no intervention (DN). Furthermore, this study demonstrates the power of a deidentified research database derived from electronic medical records.
