Patient-reported physical function as a preoperative predictor of recovery after vascular surgery.

OBJECTIVE:Preoperative risk assessment in vascular surgery often relies on the clinical subjectivity of providers and assessment tools with poor discrimination. Patient-reported outcome measures (PROMs) may provide a more objective assessment of an individual's own health status before surgery and ability to recover after a vascular procedure. We designed this study to determine whether PROMs assessed for physical function (PROM-PF) prior to vascular surgery could be used to predict patient risk for postoperative complications and delayed recovery. METHODS:We identified all patients who completed a PROM-PF survey prior to undergoing a vascular surgery procedure captured in the Society for Vascular Surgery-Vascular Quality Initiative registry (carotid endarterectomy, abdominal aortic aneurysm, endovascular aneurysm repair, thoracic endovascular aneurysm repair, peripheral vascular intervention, infra-inguinal bypass, and supra-inguinal bypass) at a single academic institution between January 2016 and June 2020. PROM-PF assessment was obtained electronically using the validated Patient-Reported Outcome Measurement Information System short form (v1.2) instrument. All patient demographics and comorbidities were collected as part of the Society for Vascular Surgery-Vascular Quality Initiative registry. After stratifying patients based on high vs low preoperative PROM-PF, multivariable regression models were used to assess the risk-adjusted odds ratios (ORs) for perioperative complications, extended hospital length of stay (LOS), and discharge to a care facility. RESULTS:A total of 240 patients (mean age, 68 years; 69% male; and 88% Caucasian) completed a PROM-PF assessment <30 days before a vascular surgery intervention, of which 54% had low PF. Patients with high PF were more likely than those with low PF to undergo an open vascular procedure (43% high PF vs 42% low PF; P < .001). Rates of perioperative complications and/or mortality were similar between groups, although patients with low-PF were more likely to have an extended hospital LOS (48% low PF vs 33% high PF; P < .05) and/or be discharged to a care facility (17% low PF vs 7% high PF; P < .05). These results were confirmed in risk-adjusted models showing that patients with low PF scores were significantly more likely to have an extended LOS (adjusted OR, 1.86; 95% confidence interval, 1.06-3.28) and be discharged to a care facility (adjusted OR, 2.72; 95% confidence interval, 1.06-7.00). CONCLUSIONS:Low preoperative PROM-PF was associated with a higher risk of extended inpatient LOS and discharge to a care facility following vascular surgery. PROMs allow patients to provide valuable presurgical information about their own health status that can be used to anticipate postoperative recovery.
