Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The pharmacy will package and distribute both the cranberry capsule and placebo using a coded number on identical bottles. The researchers and care staff will not be aware of the allocation of capsules.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)

Summary
Brief summary
This project seeks to provide evidence for managing urinary tract infection (UTI) using cranberry for an elderly population. Such evidence is important because UTI causes pain and negatively impacts on the quality of life of elderly residents. While there is a growing literature on the use of cranberry for the prevention of UTI, this evidence needs to be further explored within an elderly population specifically. This study will determine if cranberry capsules have an effect on UTI incidence and which particular symptoms and characteristics of bacteriuria it has the greatest effect on.
