title: [Study on quality assurance in the prevention and therapy of decubitus ulcer by measuring the overlay pressure with test subjects on different prophylaxis systems].
abstract: The aim of this study on quality assurance in prevention and treatment of bedsores was to analyse the current state of treatment of pressure sores at the University Hospital in Marburg. Measurements of pressure exerted on the skin were taken of six soft storage systems and five alternating pressure systems. In addition, the study aimed to find out whether the applied method of pneumatic pressure measurement could be used with patients in every day nursing and whether reliable and valid data could be generated from patients who have already developed bedsores. In order to answer these questions measurements were taken on 23/19 patients, including patients in lateral position, placing measuring instruments between the mattress/bed system and the body. The soft storage systems results prove a significant pressure reduction at all measuring points (p < 0.05), at the os coccygis even a highly significant pressure reduction (p < 0.01). The alternating pressure systems results show that the average maximum pressure over 12 min lies between 56.39 mmHg and 38.94 mmHg with differing amplitudes (75.47 mmHg-5 mmHg) and alternating frequency (1.5 min-10 min).
