Oral anticoagulants are prescribed to approximately 5% of seniors and require diligent monitoring to avoid serious adverse events such as blood clots, hemorrhages and death. Monitoring warfarin use is labour intensive and challenging for both patients and medical staff.
The study, the first to use this interactive voice system, looked at an intervention where 226 patients were given medication instructions without direct human contact. Patients in the study group had stable anticoagulation control, spoke English, did not have hearing problems and 80% had been taking warfarin for more than 1 year. The system communicated information through dosage messages, appointment reminders and missed appointment messages to patients. Healthcare professionals reviewed daily web reports of the interactive voice response calls and contacted patients when dosage messages were unsuccessful.
"The interactive voice response system was effective in communicating complex information as 77.8% of messages were successfully delivered and did not require input from staff," write Dr. Alan Forster and coauthors from the Ottawa Hospital Research Institute and the University of Ottawa. "Importantly, the interactive voice response system reduced the workload of clinic staff by 33%."
Study limitations were that it included a select group of patients with stable anticoagulation control who are not representative of most community-based patients.
In a related commentary, Dr. Jerry Gurwitz of the University of Massachusetts Medical School writes that as managing warfarin therapy is expensive and labour-intensive, requiring frequent contact with patients to discuss results, provide instructions and schedule tests, "any technology-based intervention that could improve the quality and efficiency of anticoagulation care, while reducing costs, would be extremely attractive." He states that this study lays the foundation for more information-technology based approaches to oral anticoagulant management.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
