What is Person-Centered Care?

Person-centered care is a systemized approach to delivering healthcare in a way that centers on the perspective of the whole patient and their loved ones, while promoting a healthy, encouraging environment for caregivers and addressing the health needs of the organization’s surrounding community.

Person-Centered Care: The Future of Wellness

Based on growing evidence and experience partnering with organizations and patient advocates around the world, Planetree affirms that person-centered care is more than the best approach for improving healthcare outcomes. It’s a goal the entire industry is moving toward. Our Person-Centered Care Certified organizations are leading the charge in a wellness revolution, setting an example for every professional who cares for patients.

It’s as much a moral imperative as it is a blueprint for success: Person-Centered Care Certified care centers lead in HCAHPS and other patient experience scores, patient outcomes, employee satisfaction and retention, and reputation. With results like that, it’s no wonder that healthcare organizations across the globe are moving toward the person-centered model — and making their communities healthier and happier in the process.
