Intestinal Failure: Epidemiology, Catheter-Related Sepsis and Challenges.

Background The Leicestershire intestinal failure team (LIFT) service provides specialist intestinal failure care to patients in Leicestershire and surrounding counties. Aims To study the epidemiology of intestinal failure (IF) cases referred to the service and review outcomes particularly the indications and delivery of parenteral nutrition (PN). To review catheter-related sepsis (CRS) rates and identify areas for improvement. Methods Service data from January 2016 to November 2017 was analysed retrospectively. Descriptive and inferential statistical analysis was carried out. Chi-square/Fisher Exact tests were used to identify significance on categorical data and non-parametric settling was used for qualitative data analysis. Results A total of 365 patients were referred to the service from January 2016 to November 2017. 58% patients had grade I intestinal failure. 34% and 24% referrals were made by the colorectal and hepato-pancreato-biliary (HPB) units, respectively. Gut rest (27%) and small bowel obstruction (25%) were the most common indications for nutritional support. Duration of PN requirements varied greatly, but most patients (39%) required it for up to seven days. Single lumen PICC line (64%) and cephalic vein (54%) were the most commonly used catheter and site of vascular access, respectively. Chronicity of IF and number of vascular catheters required to provide PN were significantly associated with rates of CRS. Conclusion CRS was found to be statistically significantly associated with chronic IF and number of vascular access catheters required to provide PN. Cost implication and morbidity of CRS could be analysed further to identify other ways to provide safer and cost-efficient parental nutrition for patients with intestinal failure.
