Malnutrition is common in surgical patients. Many studies have shown a clear association between malnutrition and poor surgical outcomes. Parenteral nutrition (PN) is a nutrition intervention that is given by vein and can be safely provided to malnourished patients. It contains carbohydrates, fats, and protein just like you would normally in your diet. Pre-operative PN is able to improve outcomes in surgical patients. However, pre-operative PN has traditionally required hospital admission which results in increased length of stay, hospital cost, and hospital-acquired infection. Moreover, in hospital pre-operative PN may not be feasible or prioritized when access to inpatient surgery beds is limited. Outpatient PN provides the opportunity to solve this problem. The feasibility and impact of outpatient PN in malnourished patients undergoing major surgery have not previously been studied. This study aims to evaluate the feasibility of outpatient pre-operative PN and its effect on patient's outcomes.

| Measure | Description | Time Frame |
|---|---|---|
| Rate of parenteral nutrition completion | Rate of parenteral nutrition completion calculated by the number of patients who can complete parenteral nutrition before surgery for 5-10 days divided by total number of patients in parenteral nutrition group | through study completion, an average of 1 year |
| Postoperative complications evaluated by Clavien-Dindo Classification | Clavien-Dindo Classification classifies postoperative complications into 5 grades (grade I to grade V) from mild to severe complications Grade I: no need specific intervention Grade II: need phamacological treatment Grade III: need surgical/endoscopic/radiological intervention Grade IV: life-threatening complications requiring ICU managment Grade V: death of a patient | through study completion, an average of 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Length of hospital stay | Duration between hospital admission to discharge | through study completion, an average of 1 year |
| Quality of life: Short Form (SF)-12 questionnaire | Quality of life evaluated by Short Form (SF)-12 questionnaire A mental component score (MCS-12) and a physical component score (PCS-12) are calculated by summation of mental and physical questions, respectively. The score range from 0-100, which the higher score means the better quality of life. |

| Body weight | Body weight measurement in kilograms | 5-10 days during parenteral nutrition infusion |
| Nutrition status | Nutrition status evaluated by patient-generated subjective global assessment Patient-generated subjective global assessment divides a patient into 3 groups: A = well-nourished B = moderately malnourished or suspected malnutrition C = severely malnourished The total score is also calculated by summation of scores from weight, food intake, gastrointestinal symptoms, activity, metabolic demand, and physical examination. It ranges from 0-55, which the lower score means the better nutrition status. | 5-10 days during parenteral nutrition infusion |
