Dementia is associated with increased mortality and poor patient-centered outcomes after vascular surgery.

Abstract：

OBJECTIVE:Dementia has been associated with increased complications and mortality in orthopedics and other surgical specialties, but has received limited attention in vascular surgery. Therefore, we evaluated the association of dementia with surgical outcomes for elderly patients with Medicare who underwent a variety of open and percutaneous vascular surgery procedures. METHODS:We reviewed claims data from the Centers for Medicare and Medicaid Services for beneficiaries enrolled in Medicare Part A fee-for-service insurance from January 1, 2011, to December 31, 2011, who underwent inpatient vascular surgery. Only the first surgery during the first admission was considered for analysis. Traditional outcomes (30- and 90-day mortality, intensive care admission, complications, length of stay) and patient-centered outcomes (discharge to home, extended skilled nursing facility [SNF] stay, time at home) were adjusted for patient and procedure characteristics using multilevel linear or logistic regression as appropriate. All analyses were performed using SAS (v9.4, SAS Institute Inc, Cary, NC). RESULTS:Our study included 210,918 patients undergoing vascular surgery, of whom 27,920 carried a diagnosis of dementia. The average age of the entire cohort was 75.74 years, and 55.43% were male. Patients with dementia were older and had higher rates of comorbidities compared with patients without a dementia diagnosis. The three most common defined classes of intervention excluding miscellaneous ones were cerebrovascular, peripheral arterial, and aortic cases, which jointly accounted for 53.15% of cases. Among all cases, 56.62% were open. Emergent/urgent cases were more frequent amongst those with dementia (60.66% vs 37.93%; P < .001). After adjustment, patients with dementia had increased odds of 30-day mortality (odds ratio [OR], 1.21; P < .0001) and 90-day mortality (OR, 1.63; P < .0001), extended SNF stay (OR, 3.47; P < .0001), and longer hospital length of stay (8.29 days vs 5.41 days; P < .001). They were less likely to be discharged home (OR, 0.31; P < .0001) and spent a lower fraction of time at home after discharge (63.29% vs 86.91%; P < .001). Intensive care admission and inpatient complications were similar between the two groups. CONCLUSIONS:Dementia is associated with poor traditional outcomes, including increased 30- and 90-day mortality and longer hospital lengths of stay in this large national patient sample. It is also associated with worse patient-centered outcomes, including substantially lower discharge rates to home, less time spent at home after discharge, and higher rates of extended stay in a SNF. These data should be used to counsel patients facing vascular surgery to provide goal-concordant care, particularly to patients with dementia.
