Clinical Effectiveness of Continuous Pressure Monitoring Systems for Pressure Ulcer Prevention: A Scoping Review

There are many circumstances where individuals with limited mobility are exposed to prolonged postures increasing the risk of pressure ulcers. Technologies have been developed to monitor posture, mobility and pressure exposure; however, their effectiveness in different clinical settings is unknown. The aim of this scoping review was to assess clinical studies using continuous pressure monitoring for the prevention and/or treatment of pressure ulcers. A scoping review of the literature was conducted using the PRISMA-ScR framework. Clinical-based studies were included which used continuous pressure monitoring for assessment and treatment over a minimum of a 2-h period. The outcomes included quantitative measures such as pressure distribution and mobility data, qualitative insights relating to patient comfort and acceptability, and the perceptions of healthcare staff regarding usability and clinical integration of the technology. Twenty-four studies were identified and included in the scoping review, conducted across eight countries spanning three continents. Most studies were undertaken in a hospital setting (67%, n = 16). Following review of the included papers, five core themes were identified: clinical outcomes, pressure metrics, posture and mobility, nurse feedback and patient experience. There was high heterogeneity in study design, outcome measures and different risk of bias limited the scope to synthesise the outcomes. Collectively, the studies indicate that CPM can enhance awareness of interface pressures, support clinical decision-making and inform repositioning strategies for individuals at risk of tissue damage. Reported benefits include greater staff confidence and patient engagement. However, consistent reductions in ulcer incidence have yet to be demonstrated, with larger trials with standardised outcomes required.
