Incidence, timing and variation in unplanned readmissions within 30-days following isolated coronary artery bypass grafting.

Background: Coronary Artery Bypass Grafting (CABG) is the most common cardiac surgery, yet little is known about unplanned readmissions after CABG despite increasing clinical and policy focus on reducing readmissions. We assessed the incidence, timing, and reasons for unplanned readmission within 30 days of CABG and evaluated for variation in readmission rates across hospitals in Australia and New Zealand (ANZ).

Method: We identified isolated CABG procedures from 2013 to 2017 across all public and most private hospitals in ANZ.

Institutional variation in early mortality following isolated coronary artery bypass graft surgery.

Background: Thirty-day mortality following coronary artery bypass grafting (CABG) is a widely accepted marker for quality of care. Although surgical mortality has declined, the utility of this measure to profile quality has not been questioned. We assessed the institutional variation in risk-standardised mortality rates (RSMR) following isolated CABG within Australia and New Zealand (ANZ).

Partial nephrectomy has become the preferred treatment option for small renal masses. In particular, minimally invasive partial nephrectomy (MIPN) using laparoscopic or robotic approaches has shown decreased blood loss, shorter hospital stay, and faster return to normal activity compared to open surgery. However, MIPN still carries risk of postoperative complications including hemorrhage and urine leakage.
