    Abstract:
    BACKGROUND: Although international guidelines support the use of commercially available multichamber bags (MCBs), the majority of home parenteral nutrition (HPN) in the United Kingdom has been compounded PN, tailored to the patient. However, national capacity limitations in aseptic facilities have necessitated the increased use of MCBs. There are no studies evaluating the appropriateness or benefits of using a "hybrid" regimen incorporating both MCBs and compounded PN in patients already established on compounded HPN. METHODS: This was a cross-sectional audit evaluation conducted on September 1, 2021, at a national United Kingdom reference center. All HPN-dependent adults prescribed HPN for chronic intestinal failure were assessed by a multidisciplinary team for their potential of being switched to a "hybrid" regimen of MCBs and compounded PN. RESULTS: Of 180 patients currently receiving compounded HPN that included intravenous nitrogen with glucose ± lipid, 65 (36.1%) were deemed clinically suitable for a hybrid PN regimen, with minimal variance in PN constituents per week (volume 0%, non-nitrogen kilocalories 0%, nitrogen 0%, fat -0.2%, glucose 0%, sodium 0%, potassium 0%, calcium 0%, magnesium 0%, and phosphate -0.1%) and requiring no additional central venous catheter manipulations. The potential reduction in compounded PN would reduce by 3627 bags per year, equating to a cost saving of £141,453 per year (equivalent to $178,885). CONCLUSION: Wider use of hybrid MCB/compounded HPN regimens could lead to a reduction in the need for compounded PN to be produced by aseptic facilities. Further evaluation of acceptability and tolerance of hybrid regimens by patients already receiving compounded HPN is required.
