Hospital readmission after cardiac surgery. Does "fast track" cardiac surgery result in cost saving or cost shifting?
Readmission after cardiac surgery is common and frequently (49%) to outside institutions. Patients discharged>or = 7 days postoperatively represent the patients at greatest risk of readmission and, therefore, warrant closer scrutiny before discharge.
In a retrospective database analysis, taking into account potential time-related biases, no reduced cancer risk was found in metformin users. To clarify the association between diabetes medication and cancer risk, further well-designed observational studies and RCTs are needed.
