About

This single-blinded (only patients blinded) study is to assess the effect of cooling beddings on itch.

The primary objective is to test whether or not the use of the cooling beddings during 3 days can add at least 20% improvement in (nocturnal) itch as measured by the 0-10 NRS in comparison to a control group that does not use the cooling beddings.

Full description

Itch is the most common skin-related symptom. Staying/sleeping in a bed with a cooling properties could have a positive effect on (nocturnal) itch intensity, sleep quality and daytime performance in consequence. A mattress topper and bed linen with cooling effects that are commercially available (https://www.oba.ch/cool_gel_topper) by the OBA AG (Basel), which is the supplier of beds and bedding items of the University Hospital Basel, has been used in clinical routine. This single-blinded (only patients blinded) study is to assess the effect of cooling beddings on itch and to better rationalize the beddings 'use. No comparative data is available and the design is purely exploratory. The primary objective of this study is to test whether or not the use of the cooling beddings during 3 days can add at least 20% improvement in (nocturnal) itch as measured by the 0-10 NRS in comparison to a control group that does not use the cooling beddings.

Description:
Cooling beddings: linen made of the Outlast Technology https://www.outlast.com/en/. This product is made of 100 % lyocell and utilizes phase change materials based on natural wax. When this phase change material melts, heat is extracted from the environment and stored in microcapsules called thermocules. When the body cools down, these thermocules harden again release the heat from the linen. This might help to balances the body temperature and prevent warmth-aggravated itch. - The mattress is made of polyurethane foam and designed as a "cool gel" topper to be placed onto the standard hospital mattress. Heat is also absorbed and stored into this topper. This topper is covered with an Obatex cover. It protects the "cool gel" topper from moisture and organic liquids and is made of polyamide fabric.
