Design outcomes

Primary

MeasureTime frame
Patient outcome measures: 1. Number of doses of ibuprofen or other NSAID administered to each patient within 5 days after surgery, measured by reviewing the patient's medical records 2. Clinical effects of oral ibuprofen in reducing pain after major elective gut surgery measured using the Overall Benefit of Analgesia Scores (OBAS) recorded daily for 5 days after surgery 3. Total opioid dose (Oral Morphine Equivalents) within 5 days after surgery, measured by reviewing the patient's medical records 4. Clinical effects of oral ibuprofen in reducing pain after major elective gut surgery measured using the Numeric Rating Scale (NRS) pain scale on postoperative days 1 to 5 5. All complications within 30 days of surgery, measured by reviewing the patient's medical records 6. Mortality within 30 days of surgery, measured by reviewing the patient's medical records 7. Duration of hospital stay within 30 days of surgery, measured by reviewing the patient's medical records 8. Anastomotic leak graded within 30 days of surgery, measured by reviewing the patient's medical records 9. Acute kidney injury (KDIGO creatinine definition only) within 30 days of surgery, measured by reviewing the patient's medical records 10. Gastro-intestinal bleed within 30 days of surgery, measured by reviewing the patient's medical records Hospital-level feasibility outcomes: 1. Number of eligible patients per year in each hospital, measured using screening log data 2. Number of eligible patients randomised per year in each hospital, measured using screening log data 3. Participating hospitals randomising at least one patient within the 12-month recruitment period, measured using enrolment data 4. Number of consultant surgeons and anaesthetists in each hospital who support the recruitment of patients in their care in principle and the total number delivering care for elective colorectal surgery, measured using the feasibility site questionnaire
