Supplementary Material 2: Additional Appendices Appendix A. Scope 1. Guideline title The use of faecal microbiota transplant as treatment for recurrent or refractory Clostridium difficile infection and other potential indications: joint British Society of Gastroenterology (BSG) and Healthcare Infection Society (HIS) guidelines. 1.1. Short title The use of faecal microbiota transplant 2. The remit i. To review the evidence (include randomised trial evidence) for the efficacy of faecal microbiota transplant (FMT) in the treatment of adults (≥18 years), both in Clostridium difficile infection (CDI) and in other clinical conditions, and use this to make recommendations about optimal recipient selection and management, donor assessment, material preparation and administration, and other key elements of FMT delivery. ii. To provide specific guidance about best practice for an FMT service within the context of the regulatory framework for the intervention as it currently exists in the UK and beyond. Whilst this is not a guideline specifically addressing the management of Clostridium difficile infection (CDI), the working group will include consideration of where FMT should be considered within the conventional treatment algorithm of patients with CDI (specifically, in which patients it should be considered, and at which point in their care). The working group agreed that for the purposes of this guideline, faecal microbiota transplant would be defined as treatment that involves the administration of manipulated whole stool. 1 Supplementary Material 2 for Gut There is a growing literature of the use of ‘bacteriotherapy’ originally deriving from healthy donor stool as a potential alternative to FMT (including commensal bacteria, spores, bacteriophages and/ or bacterial proteins or metabolites). However, the working group considered this to still be at the research stage, and would not be considered further. 2.1. Population 2.1.1. Groups that will be covered Adults (≥18 years) in whom: i. FMT has been used as treatment for CDI. ii. FMT has been used as treatment for a non-CDI indication. Given the variability in the means used to diagnose CDI within different studies, the working group agreed to consider the suitability of the definition used on a study-by-study basis. 2.1.2. Groups that will not be covered Children and young people (<18 years). 2.2. Healthcare setting All settings in which National Health Service care is received, and/ or clinical trials are undertaken. 2.3. Clinical management 2.3.1. Key clinical issues that will be covered a) Appropriate selection of patients with CDI for FMT, and best practice in their management post- FMT. b) Optimal selection of donors of faecal material, and maintenance of a donor pool. c) Identification of the preferred means of preparation and administration of FMT to recipients. d) Evaluation of the safety and efficacy of FMT in treating non-CDI indications. e) Best practice in the development and delivery of an FMT service. 2.3.2. Clinical issues that will not be covered a) General management of CDI. 2 Supplementary Material 2 for Gut b) General management of non-CDI conditions in which FMT may have a role in therapy. 2.4. Main outcomes Recommendations for practice a) Patient/ recipient selection, and peri-FMT management b) Donor selection c) Preparation and administration of FMT d) Efficacy and safety of FMT for non-CDI indications e) Provision of an FMT service 2.5. Economic aspects Where FMT is being provided under a MHRA license according to Good Manufacturing Practice (GMP) standards, there are significant costs associated with initial setup and maintenance of the service. These include the cost of obtaining the relevant license, laboratory design and equipment to enable quality assurance, storage facilities for samples, etc. However, there is counterbalance to this, as the expectation of the working group is that the publication of this guideline may encourage provision of FMT as treatment for recurrent or refractory CDI. This has consistently been shown to be cost effective in comparison with anti-C. difficile antimicrobial therapy31–34, so overall costs associated with treating the condition may actually decrease. Furthermore, there may be changes to the practice of clinicians already offering the service. For example, encouraging the use of healthy unrelated donors (who can provide multiple stool donations after one screening) reduces the cost of screening when compared to the use of an FMT recipient’s relative as donor, who is likely to provide one donation only. 2.6. Status 2.6.1. Scope This is the final scope. 2.6.2. Timing The development of the guideline recommendation will begin in July 2017. 3 Supplementary Material 2 for Gut 3.
