A new clinical study by researchers at Stanford Health Care looked at whether a wearable patient sensor could improve patient outcomes. The study, “Effect of a wearable patient sensor on care delivery for preventing pressure injuries in acutely ill adults: A pragmatic randomized clinical trial (LS-HAPI study)” is available in the current online issue of International Journal of Nursing Studies. The study found that patients randomized to be treated by Leaf were 73 percent less likely to develop a pressure injury. The optimized care delivery enabled by Leaf translated into a significant reduction in hospital-acquired pressure injuries. The study can be found through PubMed.

The investigator-initiated, prospective, blinded, randomized, controlled trial involved over 1,200 patients and over 100,000 hours of data was analyzed. Patients were randomized to either a treatment or control group. In the treatment group, the Leaf sensor was used to help ensure that patients were repositioned with sufficient frequency and quality. The Leaf sensor continuously monitors all patient movements and is designed to notify providers if repositioning is required to prevent a pressure injury. The sensor seamlessly monitors patient position and activity, regardless of whether they are in bed, a chair, or ambulating.

Several studies have shown the Leaf System improves patient turning/mobility, reduces pressure injury rates, helps nurses prioritize patient care, improve caregiver workflow, and saves hospitals non-reimbursed costs associated with the treatment of pressure injuries.
