About this study
Official title: Prevalence of Preoperative Malnutrition and Changes in Nutritional Status Following Preoperative Nutrition Education in Surgical Patients Attending a Preoperative Clinic
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.
Read the detailed description
Preoperative nutrition risk or malnutrition negative impacts patients' ability to tolerate surgical stress, impairs wound healing, delays postoperative physical recovery, prolong hospital stay, and increases risk of infection, anemia, impaired gut function, skeletal muscle loss, overall postoperative complications, and healthcare cost.1-6 Importantly, preoperative nutrition status is a modifiable risk factor that can be optimized to improve surgical outcomes.6 However, malnutrition screening is not yet routinely integrated into all surgical pathways.7 Furthermore, only a small proportion of at-risk patients receive preoperative nutrition therapy.7,8 Recent literatures reports that up to 65% of patients admitted for surgery are either malnutrition or at risk of nutrition.7,9-11 This highlights the necessity of preoperative nutrition screening and intervention are needed to enhance postoperative outcomes. The importance of nutritional optimization extends beyond the immediate preoperative period and into the preadmission phase, forming a critical component of the perioperative care continuum, as emphasized by Enhanced Recovery After Surgery (ERAS) guidelines and prehabilitation program.12 Increased awareness has led to several strategies, including preoperative nutrition education, reducing of perioperative fasting, introduction of oral carbohydrate loading before surgery, and early postoperative feeding -all contributing to improved recovery.13,14 Despite growing awareness, considerable variation exists in the tools and criteria used to screen and assess malnutrition, which contributes to inconsistent prevalence data and may hinder timely intervention. Various nutrition screening tools are used worldwide, including the Malnutrition Screening Tool-Short Form (MST-SF), Mini Nutritional Assessment -Short Form (MNA-SF), Nutrition Risk Screening 2002 (NRS-2002), and the Malnutrition Universal Screening Tool (MUST). In Thailand, the SPENT Nutrition Screening Tool, endorsed by the Society of Parenteral and Enteral Nutrition of Thailand (SPENT), is commonly used in clinical settings. For more comprehensive evaluation, nutritional assessment tools such as the Subjective Global Assessment (SGA), Patient-Generated Subjective Global Assessment (PG-SGA), Global Leadership Initiative on Malnutrition (GLIM) criteria, Mini Nutritional Assessment (MNA), and the ASPEN/Academy of Nutrition and Dietetics Malnutrition Indicators (AAIM) are applied internationally. The modified Nutrition Alert Form (NAF), a simplified nutrition assessment tool, is also widely used in Thailand for preoperative patients due to its practicality and ease of use.15-17 This heterogeneity of tools, each incorporating different parameters and thresholds-such as BMI, recent weight loss, dietary intake, and disease burden-results in variability in sensitivity and specificity, complicating comparisons and underscoring the need for standardization tailored to surgical patients.
The reported prevalence of malnutrition in surgical patients varies widely depending on the type of surgery, socioeconomic background, presence of malignancy, and the screening tool used.15 Preoperative malnutrition screening creates an opportunity to identify and optimize the nutritional status of at-risk patients before surgery. Nevertheless, it remains underutilized due to barriers such as time limit and lack of awareness.16,17 The primary aim of this study is 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. The secondary aim is to evaluate the impact of preoperative nutrition education on body weight and nutrition status prior to surgery.

What is being measured
The primary outcome is the main question the study is designed to answer.
The prevalence of malnutrition using NAF score
The prevalence of malnutrition using Modified Nutrition Alert Form (NAF) score The minimum value for the NAF (Nutritional Assessment Form) is 0 and the maximum value is 88. The NAF uses a combination of BMI, serum albumin or total lymphocyte count to assess nutritional status, with scores ranging from 0-5 (NAF = A, normal to mild malnutrition), 6-10 (NAF = B, moderate malnutrition), and 11 or higher (NAF = C, severe malnutrition).
Measured: Baseline
Secondary outcomes (1)
The change in Modified NAF score
Changes in Nutrition status measured with change in Modified Modified Nutrition Alert Form (NAF) score. The minimum value for the NAF (Nutritional Assessment Form) is 0 and the maximum value is 88. The NAF uses a combination of BMI, serum albumin or total lymphocyte count to assess nutritional status, with scores ranging from 0-5 (NAF = A, normal to mild malnutrition), 6-10 (NAF = B, moderate malnutrition), and 11 or higher (NAF = C, severe malnutrition).
Measured: Preoperative period (up to 12 weeks before surgery)

Questions about this trial
What is this clinical trial studying?
An observational study of Nutrition Status, run by Siriraj Hospital at 1 site in Thailand.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 27 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Thailand. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mingkwan Wongyingsinn, MD (+66 81-915-3320, Mingkwan.won@mahidol.ac.th), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The prevalence of malnutrition using NAF score (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07125859, which also lists 21 linked publications.
