Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Prospective, non-randomised, non-blinded clinical trial comparing two patient groups over two consecutive time periods.

Group 1 (Standard Care) – Patients have CRP levels measured on postoperative days 3 to 5 via a simple peripheral venous blood test which will be collected by a phlebotomist or doctor from the surgical team. A septic screen is performed based on the patients clinical status (vital signs, examination findings) rather than CRP alone.

Group 2 (CRP protocol group) - Patients have CRP levels measured on postoperative days 3 to 5 as for Group 1. If the CRP value is above certain thresholds on these days (>170mg/L on day 3, >125mg/L on day 4, or >50mg/L increase between day 3 and 4, or between day 4 and 5), a 'septic screen' will be performed on the same day to look for a source of infection regardless of normal vital signs or examination findings. This will include:
- CT scan of the abdomen and pelvis
- Chest x-ray
- Cultures of urine, wound and blood/central lines

Fidelity of this data will be ensured through prospective collection of CRP data and complications and further assessed through audit of electronic records and hospital notes at the end of the study.
Intervention code [1] 315327 0
Diagnosis / Prognosis
Comparator / control treatment
The interventional group will be compared to standard care where a septic screen is performed based on clinical status of the patient rather than routine blood tests. This is assessed by doctors on the surgical team and based on the patient's symptoms, vital signs, and physical examination.
Control group
Active

Outcomes
Primary outcome [1] 321105 0
Infectious complications (e.g. wound infection, chest infection, urinary tract infection, anastomotic leak, abdominal collection).
These will be assessed by the surgical team as part of routine clinical care and postoperative follow-up. They will be prospectively recorded by the principal investigator and research team.
Timepoint [1] 321105 0
Assessed daily while in hospital and then weekly once discharged until 30 days post surgery.
Secondary outcome [1] 374003 0
Re-intervention - composite of return to operating theatre or requiring radiological drainage.
These will be assessed by the surgical team as part of routine clinical care and postoperative follow-up. They will be prospectively recorded by the principal investigator and research team.

Summary
Brief summary
The purpose of this study is to evaluate a diagnostic blood test (C-reactive protein) to detect infection and inflammation in the first 3-5 days following bowel surgery.

Who is it for?

You may eligible for this study if you are 18 years or older and undergoing elective colonic or rectal resection with a primary anastomosis at Lyell McEwin Hospital.

Study details

Patients enrolled in the study will be allocated into two groups, the control and intervention group. Participants in the control group will be monitored via standard care protocols at the hospital. The intervention group will have a blood test with a small needle in the arm on days 3, 4 and 5 after surgery. If the CRP value is above certain thresholds on these days, a 'septic screen' will be performed to look for a source of infection. The assessments that you may be involved in include, a CT scan, chest x ray, wound swab and urine/blood tests.

It is hoped this research will help determine if using a clinical protocol based on the CRP to perform an infection screen will allow earlier detection of infectious complications following major colorectal surgery. It is hoped this will also allow for earlier intervention and treatment.
