E-Mail Researchers saw a fourfold decline in the rate of patients who needed to go back to the hospital after total hip or knee replacements if they were enrolled in a program that used wearable step counters and conversational text messaging to keep tabs on recovery. The study was published in JAMA Network Open today. "There are great opportunities for health systems and clinicians to improve the quality and value of care for patients getting hip and knee joint replacement surgery, and some of the most important advances are focused on what happens when patients return home," said the study's lead author, Shivan Mehta, MD, associate chief innovation officer at Penn Medicine. "Technology, behavioral science insights, and care redesign can help to improve care at home and prevent patients from coming back to the hospital unnecessarily."
