Risk for malnutrition in patients prior to vascular surgery

Abstract

Background: Malnutrition is an important risk factor for adverse post-operative outcomes. The prevalence of risk for malnutrition is unknown in patients prior to vascular surgery. We aimed to assess prevalence and associated factors of risk for malnutrition in this patient group.

Methods: Patients were assessed for risk for malnutrition by the Patient-Generated Subjective Global Assessment Short Form. Demographics and medical history were retrieved from the hospital registry. Uni- and multivariate analyses were performed to identify associated factors of risk for malnutrition.

Results: Of 236 patients, 57 (24%) were categorized as medium/high risk for malnutrition. In the multivariate analyses, current smoking (P = 0.032), female sex (P = 0.031), and being scheduled for amputation (P = 0.001) were significantly associated with medium/high risk for malnutrition.

Conclusions: A substantial proportion (24%) of patients prior to vascular surgery is at risk for malnutrition, specifically smokers, females and patients awaiting amputation. Knowledge of these associated factors may help to appoint patients for screening.
