Inclusion criteria

Inclusion criteria: 1. People aged greater than or equal to 65 years, either sex 2. Admitted to hospital without diarrhoea 3. Have been exposed to one or more antibiotics within the last 7 days or are about to start antibiotic treatment

Exclusion criteria

Exclusion criteria: 1. People with known immunosuppressive disorder, prosthetic heart valve or active inflammatory bowel disease (the latter defined as requiring specific treatment in the past 12 months) 2. Acute pancreatitis (defined as abdominal pain with serum amylase or lipase concentration greater than or equal to three times the institutional upper limit of normal) 3. Jejunal tube in-situ and/or jejunal feeding (as documented in the clinical/nursing records) 4. Likely impaired splanchnic perfusion: any past or current abnormality or disease affecting the mesenteric arteries (as documented in the clinical records) 5. Severe illness requiring care in either a high dependency or intensive care unit (but not planned admission to these facilities for observation only, e.g., after cardiac surgery) 6. People with a previous history of adverse reactions to probiotics 7. Informed consent not granted by patient or their carer(s)

Design outcomes

Primary

MeasureTime frame
During antibiotic treatment and within 8 weeks of stopping antibiotics: 1. The occurrence of antibiotic associated diarrhoea (AAD) 2. The occurrence of C. difficile diarrhoea (CDD)

Secondary

MeasureTime frame
1. Severity and duration of AAD 2. Abdominal symptoms (abdominal pain, bloating, flatus, nausea) 3. Severity and duration of CDD and incidence of recurrence within the study period 4. Incidence of pseudomembranous colitis (PMC), need for colectomy, death 5. Well-being and quality of life 6. Duration of hospital stay 7. Adverse effects 8. Acceptability of the probiotic preparation 9. Viability of the probiotic at point of administration All of these outcomes will be measured during the period from participant recruitment to 8 weeks after stopping antibiotics, to a maximum of 12 weeks from recruitment. 10. Risk factors for ADD, CDD and severe disease (PMC, colectomy, death), assessed at participant recruitment
