Risk of infection for elderly using toilets with automated wash- and dry function
Toilets with a built-in, automated wash- and dry function (also called bidet toilets, shower toilets, spray toilets etc) make it easier for users who have difficulties twisting their bodies and using toilet paper. For elderly in care homes, wash and dry-toilets are used to maintain personal intergrity and reduce the need for assistance.
Question
What scientific studies and systematic reviews have been published regarding the risk of infection for elderly users of toilets with an automated wash- and dry function?
Method
A systematic literature search was performed using the following databases: MedLine, Scopus och Cinahl, as well as the International HTA Database provided by INAHTA.
Two authors independently assessed the abstracts of all identified studies.
Risk of bias in relevant systematic reviews was assessed using an assessment tool based on AMSTAR.
Identified literature
No relevant systematic reviews were identified. However, one relevant primary study was identified [1]. Primary studies are not assessed for risk for bias.
