Study information

Primary study design	Interventional
Study design	Randomised controlled trial
Secondary study design	Randomised controlled trial
Scientific title	Randomised controlled trial of thermostatic mixer valves in reducing bath hot tap water temperature in families with young children in social housing
Study objectives	To assess the effectiveness of Thermostatic Mixer Valves (TMVs) in reducing bath water temperature in the homes of families with children under the age of five years living in rented social housing.
Ethics approval(s)	Nottingham Research Ethics Committee 1 opinion given on 15th March 2005 (ref: 05/Q2403/37).
Health condition(s) or problem(s) studied	Childhood injury prevention: Bath tap water scald prevention
Intervention	The intervention will comprise: 1. Educational leaflet devised by the research team sent to participant prior to installation of TMV. 2. Installation of a TMV valve to the hot and cold water supply to the bath by a qualified plumber. The cost of the intervention will be borne by the social housing provider. The maximum temperature at which this will be set will be 44°C as agreed with the social housing provider. 3. Educational hanger on how to use TMV to be attached to the tap at installation. The control group receives no intervention or information.
Intervention type	Other
Primary outcome measure(s)	Proportion of families having bath tap hot water at or below 46°C at baseline, three and 12 months.
Key secondary outcome measure(s)	At 12 months only: Intervention group: 1. Proportion of valves: a. that fail or are replaced b. are unofficially adjusted 2. Acceptability of valves, potentially unsafe practices and adverse events in event of valve failure. In both groups: 1. Acceptability of bath hot tap water 2. Potentially unsafe practices and actual adverse events
Completion date	29/02/2008
