Pressure redistributing static chairs for preventing pressure ulcers Cochrane Database of Systematic Reviews 2022, Issue 2. Art. No.: CD013644. DOI: 10.1002/14651858.CD013644.pub2. ABSTRACT Background Sitting can be viewed as a therapeutic intervention and an important part of a person’s recovery process; but the risk of ulceration must be mitigated. Interventions for ulcer prevention in those at risk from prolonged sitting include the use of specialist cushions and surfaces, espe- cially for wheelchair users. Whilst there is interest in the effects of different pressure redistributing cushions for wheelchairs, the benefits of pressure redistributing static chairs, compared with standard chairs, for pressure ulcer development in at-risk people are not clear. Objectives To assess the effects of pressure redistributing static chairs on the prevention of pressure ulcers in health, rehabilitation and social care settings, and places of resi- dence in which people may spend their day. Search methods In June 2021 we searched the following electronic data- bases to identify reports of relevant randomised clinical trials: the Cochrane Wounds Specialised Register, the Cochrane Central Register of Controlled Trials (CEN- TRAL), Ovid MEDLINE, Ovid Embase and EBSCO CINAHL Plus (Cumulative Index to Nursing and Allied Health Literature). We also searched clinical trials regis- ters for ongoing and unpublished studies, and reference lists of relevant systematic reviews, meta-analyses and health technology reports. There were no restrictions by language, date of publication or study setting. Selection criteria We sought to include published or unpublished ran- domised controlled trials that assessed pressure redistrib- uting static chairs in the prevention or management of pressure ulcers. Data collection and analysis Two review authors independently performed study selection. We planned that two review authors would also assess the risk of bias, extract study data and assess the certainty of evidence according to GRADE method- ology. Main results We did not identify any studies that met the review eligi- bility criteria, nor any registered studies investigating the role of pressure redistributing static chairs in the preven- tion or management of pressure ulcers. Authors’ conclusions Currently, there is no randomised evidence that supports or refutes the role of pressure redistributing static chairs in the prevention or management of pressure ulcers. This is a priority area and there is a need to explore this inter- vention with rigorous and robust research. Plain language summary Do pressure redistributing static chairs help to prevent pressure ulcers? Key messages Despite a comprehensive search, we did not find any studies that looked at whether pressure redistributing static chairs help to prevent or manage pressure ulcers. This is an important topic area and high quality research is needed to determine whether or not such chairs bene- JOURNAL OF WOUND MANAGEMENT OFFICIAL JOURNAL OF THE EUROPEAN WOUND MANAGEMENT ASSOCIATION 130
