  1. Nutrition screening and assessment of surgical patients Surgical Nutrition Training Module Level 1 Philippine Society of General Surgeons Committee on Surgical Training

  2. Objectives • To discuss body composition analysis in surgical patients • To discuss ways to improve body composition and function to improve outcomes in surgery

  3. Muscle and fat mass, all ages

  4. Body compartments in health and disease CARBO + OTHER (1%) PROTEIN (14%) PROTEIN (14%) PROTEIN (12%) PROTEIN (6%) FAT (23%) FAT (15%) FAT (25%) FAT (30%) WATER (72%) WATER (70%) WATER (60%) WATER (55%) OBESE NORMAL STARVATION CRITICAL CARE

  5. Loss of lean body mass = ↑mortality LBM=Lean Body Mass Demling RH. Nutrition, anabolism, and the wound healing process: an overview. Eplasty 2009;9:e9.

  6. Principles in surgical nutrition • Surgery causes cellular damage and metabolic responses that increase energy and nutrient needs • Immunosuppressionincreases susceptibility to bacterial and other infectious agent intrusion with their corresponding side effects • Wound healing requires increased energy and nutrient needs • Malnutrition affects surgical outcome(s) • Optimum outcome is dependent on preparation, operative method, and adequate support

  7. Malnutrition detection tools Nutrition screening Nutritional assessment

  8. The surgical nutrition process All admitted patients are nutritionally screened All nutritionally at risk patients are assessed All high risk patients are given nutrition care plans Monitoring of the nutrition process is done Nutrition care plan modification / Discharge

  9. Step 1: nutrition screening Goal: To identify the nutritionally at risk patients

  10. The surgical nutrition process All admitted patients are nutritionally screened All nutritionally at risk patients are assessed All high risk patients are given nutrition care plans Monitoring of the nutrition process is done Nutrition care plan modification / Discharge

  11. Basic data requirements • Body Mass Index • <18.5 underweight • 18.5 – 24.9 normal • 25 – 29.9 overweight • 30+ obese • Severe weight loss • >5% in 1 month • >7.5% in 3 months • >10% in 6 months • Mid Arm Circumference • Male: <17.6 cm • Female: <17.1 cm Height and weight taken from regularly calibrated instruments

  12. Nutrition Screening Form for Adult and Geriatric patients

  13. Nutrition Screening Form for Pediatric patients - boys

  14. Nutrition Screening Form for Pediatric patients - girls

  15. Outcome: nutrition surveillance

  16. Nutritional assessment Goal: To identify the nutritionally HIGH RISK patients

  17. The surgical nutrition process All admitted patients are nutritionally screened All nutritionally at risk patients are assessed All high risk patients are given nutrition care plans Monitoring of the nutrition process is done Nutrition care plan modification / Discharge

  18. Nutritional Assessment and Risk Level Form

  19. Outcome: complication prediction Predicting post-operative complications based on surgical nutritional risk level using the SNRAF in colon cancer patients - a Chinese General Hospital & Medical Center experience. Ocampo R B, Kadatuan Y, Torillo MR, Camarse CM, Malilay RB, Cheu G, Llido LO, Gilbuena AA. Yr 2007.

  20. A filtering process

  21. Case discussion: nutrition screening and assessment

  22. Gastric CA • FM, 68 y/o, admitted because of gastric mass and admitted to undergo gastrectomy • Ht - 1.65m; Wt. 46 kg; BMI=16.9 • Previous wt 4 months - 52 kg; % weight loss = 11% • Ancillary procedures: • Chest Xray: old (?) PTB • ECG: Normal heart • CBC: Hb=10; WBC=6,000; Platelets=250,000; N%=70; L%=10 • Electrolytes: Na=130; K=3.2 • BUN =25; Creatinine=1.2 • Albumin - 3

  23. Nutrition screening • Is the BMI <18.5 or >30? • Has the patient lost weight within the last three (3) months? • Did the patient have a reduced dietary intake in the last week? • Is the patient severely ill (e.g. in intensive therapy) • YES: BMI = 16.9 • YES: lost weight (11% in the last 4 months) • YES: reduced dietary intake • NO: not severely ill NUTRITION SCREEN RESULT: NUTRITIONALLY AT RISK

  24. Nutritional assessment/Risk Level SGA: Weight loss: >10% and gastro symptoms = (grade C) (3 pts) → severe malnutrition BMI=16.9 (2 pts) Albumin=3 (less than 3: 2 pts) TLC=600 (less than 900: 2 pts) Total Risk Score=9 Nutritional Assessment = Severe malnutrition Risk Level =High Risk of developing nutrition related complications

  25. Final decision • Nutrition build up of this patient is mandatory for at least 5 to 10 days • Other options: • Do surgery then continuous post-operative nutrition maintenance and build up • Needs a Nutrition Care Plan • Rationale: body composition and reserves cannot provide optimum condition for good healing and fast recovery plus reduction of complications (infection, dehiscence, fistula formation)
