Research recommendation(s) from an individual piece of guidance Guidance: SEM Scanner 200 for preventing pressure ulcers Date issued: 14 October 2020 Research recommendations coming out of this guidance SEM Scanner 200, with visual skin assessment, shows promise for preventing pressure ulcers. However, there is not enough good-quality evidence to support the case for routine adoption in the NHS. A randomised controlled trial is recommended to address uncertainties about the clinical benefits of using the scanner compared with standard risk assessment. This should assess: using the scanner plus visual skin assessment compared with visual skin assessment alone for identifying pressure ulcer risk whether changes in clinical decision making from using the scanner reduce pressure ulcer incidence the clinical benefits and resource impact of using the scanner in different care settings the clinical benefits for different skin tones how well the scanner works across populations with a range of comorbidities patient-related outcome measures.
