Methods: We developed and constructed a three-level linkage intervention system for pressure sores from Jun 2017 to Dec 2018, centered at the geriatrics department of the Ninth People's Hospital of Zhengzhou, China. The changes included improving the organization structure; formulating a unified evaluation system for quantitation of pressure sore risk management; formulating and standardizing the reporting/feedback mechanism; constructing and improving three-level linkage system staff training; and establishing a quality control system for process monitoring guidance and final evaluation feedback. Results: The incidence of pressure sores significantly decreased, nursing staff’s knowledge level regarding pressure sore prevention and treatment increased, and pressure sore cure rate and care satisfaction increased. Conclusion: Implementation of a three-level linkage intervention system for pressure sores in geriatric patients and standardizing pressure injury assessment helps achieve pressure sore prevention and early intervention, effectively reduces the occurrence of pressure sores in geriatric nursing homes, increases the cure rate, and improves care satisfaction among patients.   https://ijph.tums.ac.ir/index.php/ijph/article/view/26728 https://ijph.tums.ac.ir/index.php/ijph/article/download/26728/7624
