Systematic Review: Is Prescription of Pressure-relieving Air Cushions Justified in Acute and Subacute Settings?

Summary Background/Objective Pressure injuries are a common yet largely preventable complication of hospitalisation. Whilst occupational therapists commonly prescribe pressure-relieving devices to reduce these risks, evidence to support clinical decision-making is limited. The purpose of this study was thus to examine research literature as to the efficacy of pneumatic cushions for general acute/subacute patient populations. Methods A systematic search of various databases was conducted, and the literature was then appraised using standardised inclusion/exclusion parameters. Results Three randomised controlled trials were identified that met search criteria. Conclusion Whilst there is currently preliminary evidence to support the effectiveness of pneumatic pressure-relieving cushions as compared to standard foam, specific recommendations as to a preferred make/model of cushion for use within general hospital settings are not supported at this time.
