Guidelines for colorectal cancer: effects on nutritional intervention

Area of Science:

• Clinical Nutrition
• Surgical Oncology
• Health Services Research

Background:

• Parenteral nutrition (PN) is crucial for patients with gastrointestinal insufficiency but carries risks and costs if misused.
• Optimizing PN use is essential for improving patient outcomes and managing healthcare expenses.

Purpose of the Study:

• To assess the impact of a Nutritional Support Unit and clinical practice guidelines on post-operative outcomes in elective colorectal cancer surgery.
• Evaluate changes in nutritional status, complication rates, and length of stay.

Main Methods:

• A prospective, observational study across three periods: guideline development (A), and first (B) and second (C) year post-implementation.
• Included 549 patients undergoing elective colorectal cancer surgery, analyzing nutritional status, PN use, post-operative complications (PC), nil by mouth duration (NPO), and length of stay (LOS).

Main Results:

• Post-operative parenteral nutrition (PPN) use decreased significantly from 79.1% to 12.8% (p<0.001).
• Overall post-operative complications (PC) dropped from 27.9% to 8.1% (p<0.001).
• Hospital length of stay (LOS) decreased significantly from 16 days to 11 days (p<0.001).

Conclusions:

• The establishment of a Nutritional Support Unit and adherence to clinical practice guidelines effectively optimized resource utilization.
• Unnecessary parenteral nutrition use was reduced, leading to fewer complications and shorter hospital stays for colorectal cancer patients.
