A prospective study of discharge disposition after vascular surgery

The purpose of this study was to determine what factors are predictive of a decline in independent living after vascular surgery during recovery.

Demographics, risk factors, operations, complications, wound status, and discharge disposition for all patients admitted to a tertiary vascular surgery service for any surgical procedure were prospectively recorded at the time of discharge. The declining order of dispositions at discharge were home (no professional assistance), home (professional assistance), rehabilitation facility, and skilled nursing facility.

Over a 15-month period, 380 patients underwent 442 primary operations. Primary operations included 74 (17%) carotid procedures, 38 (8%) aortic procedures, 186 (42%) extremity revascularizations, 29 (7%) major amputations, 45 (10%) minor amputations, and 70 (16%) other. There were 148 (33%) complications and 85 (20%) subsequent operations (same hospitalization); 159 (36%) open wounds occurred. Forty-six percent of the patients were discharged to home (no professional assistance), 28% to home (professional assistance), 3% to a rehabilitation facility, and 18% to a skilled nursing facility; 5% died. At discharge, 51% of patients required professional assistance, 39% had a decline in disposition, and 12% went from home (+/- professional assistance) to a facility. By multivariate regression analysis, a hospital stay more than 6 days, emergency operation, open operative wound, systemic complications, and minor amputation were significantly associated (P <.001) with a decline in disposition at discharge (odds ratios: 5.5, 3.7, 3.6, 3.6, and 2.8, respectively).

Prospective study reveals that a large proportion of patients (39%) had a decline in disposition after vascular surgery. A hospital stay more than 6 days, emergency operation, open operative wound, systemic complications, and minor amputation were strong independent predictors of decline. This information suggests modifications in treatment strategies may improve independent living status after vascular surgery and decrease the intense use of extended care resources required for this patient population during recovery.
