Early economic benefits of perioperative nasojejunal tube feeding in non-critical care adult surgical patients with gastric feed intolerance

Abstract

Background: Fluoroscopy-guided endoscopic placement of nasojejunal tubes (NJT) for perioperative short- or medium-term enteral nutrition (EN) is potentially required for anatomical gastric feed intolerance. Methods: Indication for NJT and successful insertion rates was determined. NJT insertion costs were calculated and compared with central venous catheter (CVC) insertion. Duration of NJT patency in non-critical care surgical patients was determined in days in a local cohort. EN costs were calculated over a hypothetical 28-day period factoring in expected NJT replacements due to blockage and compared with parenteral nutrition (PN) via CVC, which included routine CVC changes every 10 days. Public and private sectors were compared. Results: One hundred and two (93.6%) NJTs were placed successfully, with gastric outlet obstruction the most frequent indication (40.4%) with a median 10 days’ (range 1–68 days, IQR 6–16.75 days) usage. Irrevocable blockage occurred in 33 tubes after a median 9 days (range 3–34 days; IQR 4.75–16 days). Calculated EN costs over 28 days, including NJT replacement every 9 days, reached US$1 676.12 and PN costs with CVC replacement every 10 days, US$3 461.35 (p < 0.001) in the public sector. In the private sector PN costs at 28 days were significantly higher (p < 0.001) at US$5 261.14 compared with EN US$3 780.71. The cost benefit of EN over PN is seen after three days in the public, and four days in the private sector. Conclusion: Exponential cost saving occurs with EN via NJT over time, even when factoring in the likelihood of NJT replacements.
