An economic analysis of repositioning for the prevention of pressure ulcers.

AIMS AND
OBJECTIVES: To compare pressure ulcer incidence and costs associated with repositioning older individuals in long-term care using two different repositioning regimes.
BACKGROUND: Repositioning has not always been integrated into pressure ulcer preventative methods, with arguments that it is an expensive procedure in terms of personnel and time.
DESIGN: Participants were randomly allocated to the experimental group (n = 99; repositioned every 3 hours, using the 30° tilt) and the control group (n = 114 standard care, repositioned every 6 hours, using the 90° lateral rotation). The analysis explored the incidence of pressure ulcer development and the cost difference between the two repositioning schedules, over a 4-week period.
RESULTS: The mean daily nurse time for repositioning was 18·5 minutes (experimental) and 24·5 minutes (control). Nurse time cost per patient over the study period was €206·6 (experimental) and €253·1 (control), 96·6% of participants (experimental) remained free of pressure ulcers, compared with 88·1% (control). The cost per patient free of ulcer was €213·9 (experimental) and €287·3 (control). Projected annual costs were estimated for the 588 (53·5%) residents in the 12 study sites requiring repositioning. The cost would be €1·59 m (experimental) and €2·10 m (control), a cost difference of €510,000. This represents a difference of 58·8 hours of nurse time, equivalent to approximately 12 full time nurses across the 12 sites.
CONCLUSION: Repositioning every 3 hours, using 30° tilt, has been shown to be more effective in less costly in terms of nurse time compared with standard care. RELEVANCE TO CLINICAL PRACTICE: Repositioning individuals at risk of pressure ulcer development makes both economic and clinical sense, thereby supporting the EPUAP/NPUAP 2009 guidelines.
