Abstract
Background
Low nutritional status is common among surgical patients. A low nutrition profile is related to muscle weakness and immune suppression, which may be associated with negative outcomes. In this study, we evaluated the prevalence of low nutrition and assessed the relationship between nutritional status and length of hospital stay in surgical patients.
Methods
The study participants were patients who underwent abdominal surgery between 2016 and 2018 at our hospital. The Mini Nutritional Status Short-Form score and patient demographics, including current medical status, were extracted from the medical records. Data on anesthesia time, blood loss, and use of epidural anesthesia were also recorded. The primary study outcome was the difference in length of hospitalization from the standard duration (hospitalization = actual length of hospitalization—standard length of hospitalization).
Results
Eight hundred and thirty five patients met the inclusion criteria. Their nutritional status was classified as normal (59.0%), at risk (29.6%), or malnutrition (11.4%). Linear regression analysis revealed that nutritional status, serum albumin level, and anesthesia time were associated with the length of hospital stay.
Conclusion
Our results suggest that a low nutrition profile before surgery is associated with a prolonged hospital stay.
