Malnutrition Prevalence and Nutritional Change After Preoperative Nutrition Counseling

Preoperative nutrition risk or Malnutrition is a prevalent up to 65% of surgical patients, leading to significant negative outcomes such as increased complications, poor wound healing, and higher healthcare costs. Preoperative nutrition status is a modifiable risk factor that can be optimized to improve surgical outcomes. Preoperative malnutrition screening creates an opportunity to identify and optimize the nutritional status of at-risk patients before surgery. This study is initiated to determine the prevalence of malnutrition among surgical patients enrolled in an Enhanced recovery after surgery (ERAS) program, using the SPENT and modified Nutrition Alert Form (NAF) during their visit to the preoperative clinic and evaluate the impact of preoperative nutrition education on body weight and nutrition status prior to surgery.
