- ItemCreating telehealth networks from existing infrastructures.(2008-02-28) Harnett, BrettImplementing a telehealth program from the technical standpoint can be an engineering and financial challenge due to associated costs such as hardware software networking administration and human expertise To maximize potential and minimize costs it makes sense to leverage existing telecommunications infrastructures and tailor the program based on what is available This is especially critical in developing nations where funding is often limited
- ItemCreating telehealth networks from existing infrastructures.(2005-03-07) Harnett, BrettImplementing a telehealth program can be a financial challenge due to associated costs such as hardware software networking administration and clinical expertise To maximize potential and minimize costs it makes sense to leverage existing telecommunications infrastructures and tailor the program based on what is available
- ItemA telemedicine system for wireless home healthcare based on Bluetooth and the Internet.(2013-04-10) Zhao, Xiaoming; Fei, Ding-Yu; Doarn, Charles R; Harnett, Brett; Merrell, RonaldThe VitalPoll Telemedicine System VTS was designed and developed for wireless home healthcare The aims of this study were to design the architecture and communication methods for a telemedicine system to implement a physiologic routing hub to collect data from different medical devices and sensors and to evaluate the feasibility of this system for applications in wireless home healthcare The VTS was built using Bluetooth wireless and Internet technologies with client server architecture Several medical devices which acquire vital signs such as real time electrocardiogram signals heart rate body temperature and activity physical motion were integrated into the VTS Medical information and data were transmitted over short range interface USB RS232 wireless communication and the Internet The medical results were stored in a database and presented using a web browser The patient s vital signals can be collected transmitted and displayed in real time by the VTS The experiments verified no data loss during Bluetooth and Internet communication Bluetooth and the Internet provide enough bandwidth channels to tranmit these vital signs The experimental results show that VTS may be suitable for a practical telemedicine system in home healthcare
- ItemTelemedicine systems and telecommunications.(2006-01-27) Harnett, BrettSuccessful telemedicine requires appropriate equipment and some kind of telecommunications medium However successful telemedicine requires more than just technology The three essential components are the personnel the technology and a liberal measure of perseverance Before the technology can be selected it is necessary to consider the nature of the information to be transmitted between the sites and the time frame over which it must be sent to achieve the desired clinical goals because this will determine the choice of equipment and the telecommunications network Factors to be considered include the types of information to be transmitted the quantity of information to be transferred and security and privacy e g in Europe and the USA there has been recent legislation about data security The choice of transmission method for any telemedicine application is in practice a compromise between what one would like and what one can afford In practice various trade offs have to be made which include cost availability of the service i e the coverage bandwidth reliability and quality of service Equipment and the telecommunications medium are a necessary but not sufficient pre requisite for a successful telemedicine programme The right people are also required and they must be properly trained
- ItemTelemedicine to integrate intermittent surgical services into primary care.(2002-05-21) Doarn, Charles R; Fitzgerald, Sara; Rodas, Edgar; Harnett, Brett; Prabe-Egge, Anita; Merrell, Ronald CAssessment of the logistics economic feasibility and accuracy of presurgical and postsurgical telemedicine consultations is reported Virtual patient surgeon consults were achieved through the use of desktop and laptop computers digital video and still cameras using two communications modalities Patients were selected from rural clinics in the southern Oriente region and from communities located in the Andes Mountain range outside of Cuenca Ecuador Patients were evaluated preoperatively and postoperatively by general surgeons working with the Cinterandes Foundation a not for profit organization providing surgical care in remote regions of Ecuador in cooperation with the Ministry of Health s primary care program Preoperative and postoperative telemedicine consultations had a high measure of clinical accuracy and some economic value Data were collected from several sites throughout the country during the course of the project Formidable challenges were encountered and are reported here
- ItemTranscontinental telesurgical nephrectomy using the da Vinci robot in a porcine model.(2008-05-05) Sterbis, Joseph R; Hanly, Eric J; Herman, Barry C; Marohn, Michael R; Broderick, Timothy J; Shih, Samuel P; Harnett, Brett; Doarn, Charles; Schenkman, Noah SRobotic telesurgery has been demonstrated over long distances and offers theoretical benefits to urologic training and the care of patients in remote regions The multiple arms and three dimensional vision of the da Vinci robotic system provide a platform conducive to long distance telementoring and telesurgery Whereas prior telesurgical efforts have used dedicated lines for information transmission the public Internet offers a less expensive alternative It was the intent of this study to test the validity of using the da Vinci system in urologic telesurgery and to conduct telerobotic nephrectomies using the public Internet
