An automatic repositioning system to prevent pressure ulcers : a case series

The Danish automated Vendlet V5s repositioning system is intended to reduce pressure ulcer risk in patients and work-related musculoskeletal disorders (MSDs) in caregivers. In two Belgian nursing homes, 13 residents with mobility levels C, D and E experienced the repositioning system, operated by 35 caregivers, for 4 weeks. Data about skin condition, nursing time needed for repositioning and MSD symptoms were collected. The use of the repositioning system was not associated with the development of nor a reduction in skin problems; the study included residents who were vulnerable to or already had pressure ulcers. In addition, four pressure ulcers healed during the experiment. The research focused only on the automated repositioning system. Repositioning frequency and postures were determined by the standard nursing home protocol. Frequency depended on the support surface in use, and a limited number of patient criteria (mobility in bed, presence of bony prominences/pressure points and presence of non-blanchable erythema). In future studies, the Vendlet V5s system should be tested with a more individualised patient repositioning protocol, including more criteria such as fever and moisture. The automated system reduces nursing time so could potentially improve staff efficiency. Compared with manual repositioning, caregivers perceived fewer work-related MSD symptoms during repositioning when using the Vendlet V5s system. Controlled studies with larger samples are needed to verify these conclusions
