The lack of agreement on the use of over-shoes tends to perpetuate the
ritual of their use in general operating theatres. However, the limit
ed evidence which supports their use in such settings is not applicabl
e in a Day Surgery Unit where their use is not recommended. In order t
o reduce overt contamination in the unit theatre, a local protocol sho
uld be drawn up specifying the use of designated day unit footwear for
those that remain within the unit and for all persons entering the op
erating theatre.
