A large hospital group has lots of things to worry about. One of them is sepsis, the whole-body shutdown that can occur when a virulent infection hits a weakened immune system. It’s the number one cause of death in American hospitals. Another is pressure ulcers, a sure sign that immobile patients aren’t being properly cared for and also a gateway to mortality. Every hospital out there is fighting these and other problems by asking staff members to adhere to best practices. At Kaiser Permanente we’re making good progress.
