E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the effect of probiotics vs placebo, taken in conjunction with antibiotics, on the incidence of (AAD) in care home service users |
|
E.2.2 | Secondary objectives of the trial |
•To compare the effectiveness of probiotics vs. placebo, taken in conjunction with antibiotics, on the duration and severity of AAD in care home SUs. •To compare the effectiveness of the probiotics vs. placebo in reducing the incidence of C. difficile–associated diarrhoea (CDAD) in care home SUs. •To evaluate the impact of probiotics on Quality of Life (QoL) in care home SUs. •To evaluate the cost effectiveness of probiotics for AAD in care home SUs.

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
INCLUSION CRITERIA •Resident in a care home for 24 hours or more, with a minimum planned residential care of 1 month. •Able to provide informed consent or have a personal legal representative who can provide consent for inclusion. •If the SU takes a regular probiotic but chooses to discontinue the probiotic
|
|
E.4 | Principal exclusion criteria |
EXCLUSION CRITERIA •Severely immuno-compromised, e.g. known severe neutropenia •Has artificial heart valve in situ. •Medical history of acute pancreatitis. •Requires naso-jejunal feeding /nasogastric feeding due to difficulty of administering probiotic. •Currently has a colostomy.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome is the occurrence of at least one episode of AAD during the eight weeks following randomisation. AAD is defined as three or more loose stools (defined as a 5 – 7 on the British Stool Chart) in a 24 hour period following a period of normal stool consistency. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Between randomisation and during eight weeks following randomisation |
|
E.5.2 | Secondary end point(s) |
• Proportion of stool samples positive for Clostridium difficile toxin A or B from SUs who develop AAD during the eight week follow-up period. • Duration, frequency and recurrence of AAD during the eight-week follow-up period. • QoL, measured using EQ-5D at the point of consent, at the time of randomisation and each week during the eight-week follow-up period. • Recovery from illness that triggered antibiotic treatment. • Healthcare Resource UseHealth care utilisation costs, including GP and practice nurse consultations, other medication, procedures, investigations, hospital appointments, A&E attendances and any hospital inpatient admissions, measured at the end of the eight-week follow-up period. • Unplanned hospitalisations, including all-cause and AAD related, during the eight-week follow-up period. • Adverse Events: e.g. vomiting, abdominal pain, excessive flatulence, bloating, skin rashes, during the eight-week follow-up period. • Adherence to the antibiotic, probiotic/placebo treatment course. • All causes of mortality in the 8 week follow up period. |
