The study started to enroll participants in December 2014 and was completed in May 2018. Participants included adults partially or completely dependent for bed mobility. Statistical analysis was performed from September 2018 to December 2022.<\/jats:p>\n <\/jats:sec>\n \n Intervention<\/jats:title>\n Nursing staff using visual feedback from CBPM technology for 72 hours.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Absolute number of sensing points with pressure readings greater than 40 mm Hg, mean interface pressure across all sensing points under a patient\u2019s body, proportion of participants who had pressure readings greater than 40 mm Hg, and pressure-related skin and soft tissue changes.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n There were 678 patients recruited. After attrition, 260 allocated to the control group (151 [58.1%] male; mean [SD] age, 61.9 [18.5] years) and 247 in the intervention group (147 [59.5%] male; mean [SD] age, 63.6 [18.1] years) were included in analyses. The absolute number of sensing points with pressures greater than 40 mm Hg were 11\u202f033 in the control group vs 9314 in the intervention group (\n P<\/jats:italic>\n \u2009=\u2009.16). The mean (SD) interface pressure was 6.80 (1.63) mm Hg in the control group vs 6.62 (1.51) mm Hg in the intervention group (\n P<\/jats:italic>\n \u2009=\u2009.18). The proportion of participants who had pressure readings greater than 40 mm Hg was 99.6% in both the control and intervention groups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n In this randomized clinical trial to evaluate the efficacy of CBPM technology in the reduction of interface pressure and the incidence of PIs in a tertiary acute care center, no statistically significant benefit was seen for any of the primary outcomes. These results suggest that longer duration of monitoring and adequately powered studies where CBPM feedback is integrated into a multifaceted intervention to prevent PI are needed.<\/jats:p>\n
