Patient selection: lower extremity bypass surgery
Outcome: 30-day readmission (planned or unplanned, related or unrelated)
Unplanned, related readmissions were 75% of total.
Reasons for unplanned, related readmission included:
(1) wound complication
(2) graft failure
(3) multiple complications
Risk factors for readmission (odds ratios 1.3 to 1.5):
(1)
dependent in functional status
(2) dyspnea (pulmonary comorbidity)
(3) cardiac comorbidity
(4) dialysis dependence (chronic renal failure)
(5) obesity
(6) malnutrition
(7) surgery for critical limb ischemia (CLI)
Risk factor for readmission (odds ratio 8.0)
(1) return to the operating room on index admission
