Why the study?

Does low preoperative nutritional status worsen postoperative outcomes and increase hospital stay in noncancer surgical patients?

Population

215 noncancer patients undergoing major vascular, minor vascular, and abdominal surgery

Comparison

Low preoperative nutritional status vs Normal preoperative nutritional status

Design

Cohort

Follow-up

Postoperative hospital stay

Implication

May warrant preoperative nutritional assessment in noncancer surgery; hypothesis-generating for intervention trials.

Key Points

  • To evaluate the clinical importance of preoperative nutritional status and assess its predictive relationship with postoperative complications and duration of hospital stay in noncancer surgical patients.
  • Conducted a prospective study of N=215 noncancer patients undergoing major vascular, minor vascular, or abdominal surgery.
  • Assessed preoperative nutritional status using percentage weight loss (% WL), relative body weight (WI), arm muscle circumference (AMC), and serum albumin (S-Alb), defining malnutrition as two or more abnormal markers.
  • Correlated nutritional markers with postoperative complications and length of stay while adjusting for age, diagnosis, and surgical duration.
  • Malnutrition was present in 12% of patients overall, occurring most frequently in major vascular surgery (18%) and least in minor vascular surgery (4%).
  • Patients with low nutritional status experienced significantly longer hospital stays compared to well-nourished patients (mean 29 days vs. 14 days, p < 0.01).
  • Undernourished patients demonstrated significantly higher rates of overall complications (48% vs. 23%, p < 0.01) and serious complications (31% vs. 9%, p < 0.05).

Preoperative malnutrition is a significant predictor of increased postoperative complications and longer hospital stays in noncancer surgical patients.
