Transatlantic Telehealth Research Network (TTRN)

Telehealth Research Collaboration spans the Atlantic

The Transatlantic Telehealth Research Network (TTRN) is dedicated to developing cutting-edge research and innovation within telehealth. The research is interdisciplinary (medicine, engineering, nursing, organizational, economic, policy); and focuses on developing new diagnostic, preventive care and treatment methods/technologies for patients in their own homes utilizing telehealth. Problem-based, user-driven innovation is a key issue in international and interdisciplinary TTRN.

TTRN Mission

  • To prepare and launch an interdisciplinary, translantic research network on telehealth.
  • To develop synergy between telehealth programs between the United States and Denmark.
  • To collaborate on developing and testing new and emerging telehealth technologies.
  • Initiating a joint research program on telehealth and cardiology with a focus on new technologies for preventive care, treatment and rehabilitation of cardiac patients.
  • To develop a mutually beneficial program for exchange and knowledge-sharing for clinicians, Master’s students, PhD students and researchers within the field of telehealth.

In Vita – Invidualized Technology-Aided Assistance System in Heart Failure for Patients and Clinicians

Chronic heart failure (HF) is a complex clinical syndrome with poor prognosis. Telemonitoring has been available and in use for many years, especially in home care settings, by government agencies and by health maintenance organizations. The evidence of effects of home monitoring on heart failure patients is unclear.

The aim of this pilot study is to determine patient characteristics and device characteristics that form an ideal match between users and device as a precursor to implementing a randomized controlled trial of an innovative program of telemonitoring in HF. Subjects will be enrolled at 3 facilities: Cleveland Clinic, Cleveland OH, UC Davis, Sacramento CA and Vendsyssel Hospital, Denmark.  225 patients participated in the study. The study is conducted according to The Helsinki Declaration and is running from December 2013- November 2014. Based upon the results from the pilot phase, a 3-4 year research project will be designed and funding will be sought.

Teledi@log project

The idea behind the Teledi@log research and innovation project is to develop telerehabilitation concepts and technologies, so that all types of heart patients, regardless of severity, can be offered individualized, differentiated and coordinated telerehabilitation across sectors. The TTRN is on an International Advisory Board for the Teledi@log project.

“Heart on the right Path”

Professor Greg Niemeyer of the Social Apps Lab visits Aalborg University to facilitate a workshop in the development of a prototype of an animation tool for telerehabilitation of heart patients.
