[Less frequent turning intervals and yet less pressure ulcers]

Abstract

The aim of the doctoral dissertation summarised here, was to study the effect of different turning intervals and to optimise this method of pressure ulcer prevention. Prior to the main study, the pressure reducing effect of mattresses, cushions, sitting and lying positions was investigated. Based on the results of 3 pre-studies, 4 different turning schemes were compared in a randomised controlled trial in 838 high-risk nursing home residents. Turning every 4 hours in combination with the use of a pressure reducing viscoelastic mattress reduced the number of pressure ulcers significantly compared to the other 3 schemes: turning every 6 hours on a viscoelastic mattress, and turning every 2 or 4 hours on a non-pressure reducing mattress.
