Background: Malnutrition has been linked to poor outcomes after elective joint arthroplasty, but the risk of unplanned postoperative intensive care unit (ICU) admission in malnourished arthroplasty patients is unknown.
Methods: 1098 patients were followed as part of a prospective risk stratification program at a tertiary, high-volume arthroplasty center. Chronic malnutrition was defined as preoperative albumin
Results: The overall incidence of malnutrition was 16.9% (primary and revision arthroplasty patients). Average BMI was highest for patients in albumin category 3.0-3.5 (BMI 35.7). Preoperative albumin postoperative ICU admission.
Conclusion: Patients with poor nutritional status must be counseled on the risks of adverse medical complications.
