Medicare risk-adjusted outcomes in elective major vascular surgery.

摘要: Abstract Background Risk-adjusted outcomes of elective major vascular surgery that is inclusive inpatient and 90-day post-discharge adverse together have not been well studied. Methods We studied 2012–2014 Medicare inpatients who received open aortic procedures, peripheral endovascular percutaneous angioplasty procedures the lower extremity for risk-adjusted deaths, 3-sigma prolonged length-of-stay outliers, deaths without readmission, associated readmissions after excluding unrelated events. Observed predicted total hospitals meeting minimum risk-volume criteria were assessed hospital-specific z-scores calculated to compare performance. Results The adverse-outcome rate was 27.8% 31.5% 19.6% 36.4% procedures. difference in rates between best- poorest-performing deciles 32.2% 29.5% 21.5% 37.1% driver overall rates. Conclusion variability among over 20% all indicates a large opportunity exists improvement results.
