GRIFFIN HOSPITAL TO IMPLEMENT VREE HEALTH’S TRANSITIONADVANTAGE™ TO HELP PATIENTS TRANSITION FROM HOSPITAL TO HOME Post-Discharge Service Helps Patients and Caregivers Follow Care Plans and Improve Quality of Care North Wales, Pa. – May 14, 2013 – Vree Health, a subsidiary of Merck focused on technology-enabled services designed to improve the reach, cost-efficiency and efficacy of healthcare, today announced that Griffin Hospital will implement Vree Health’s TransitionAdvantage™, a post-discharge service designed to help hospitals reduce preventable 30-day patient readmissions. By engaging patients on a daily basis and improving coordination across care providers, TransitionAdvantage is designed to help patients adhere to the hospital’s recommended post-discharge care plan. “Helping patients transition from hospital to home is a major healthcare challenge that requires providing individual attention for each patient after they leave the hospital,” said Kathleen Martin, vice president for Patient Safety and Care Improvement at Griffin Hospital. “As part of our commitment to being a leader in preventing hospital readmissions, Griffin Hospital is excited to be implementing TransitionAdvantage as part of our efforts to support patients during their post-hospital recovery.” According to the authors of a study recently published in the Journal of the American Medical Association, “Medicare beneficiaries experience errors during transitions among care settings, yielding harms that include unnecessary rehospitalizations.”[i]. Griffin Hospital aims to facilitate care coordination by providing patients and their caregivers with access to TransitionAdvantage’s Transition Liaisons, who help keep caregivers up to date about the patient’s medications, care plan, health records, appointments and other important information. The TransitionAdvantage service will also engage patients through digital communication tools and daily health checks, collecting vital signs and other key data used to identify conditions that may signal health issues before they become serious and costly. “We are honored to be working with Griffin Hospital, which is nationally recognized for its patient-centered approach under the Planetree Model of Care, as well as its high quality of care and innovative approach to engaging the community to improve patient care,” said Kyle Dolbow, president of Vree Health. “Vree Health will provide the infrastructure, people and technology to help Griffin extend their resources to provide high-quality care to patients after they leave the hospital.” About Griffin Hospital Griffin Hospital, located in Derby, Conn., is a 160-bed acute care community hospital serving more than 107,000 residents of the Lower Naugatuck Valley Region of the state.
