Elective surgery deaths occur at a significantly higher rate when surgery is performed on a Friday, Saturday or Sunday. Worse outcomes for patients admitted on weekends compared with weekdays measured by death and length of stay are explained as the "Weekend Effect". A recent study in the British Medical Journal confirmed the higher risk of death and complications for surgeries done at the end of the week and on weekends. The risk of dying from surgery on Saturday or Sunday was almost double the risk (82% higher) when surgery was performed on Monday. The risk of dying from surgery on a Friday was 44% higher than on a Monday. The elective surgeries that were looked at were colon resection, coronary artery bypass grafting (CABG), repair of abdominal aortic aneurysm, lobectomy or lung resection and a single combined group that included hip replacement, knee replacement, inguinal hernia repair, varicose vein stripping and ligation, tonsillectomy, femoral hernia repair and abdominal wall hernia repair.
