Telemedicine in extreme conditions: supporting the Martin Strel Amazon Swim Expedition.

Slovenian Martin Strel, the Guinness world record holder in ultra marathon swimming, recently set a new world record by swimming the entire Amazon River. Over a 66-day period beginning in Atalaya, Peru, he swam to the Atlantic Ocean at Belém, Brazil. This record-breaking swim was part of the Amazon Swim Expedition. This entire mission was supported by a comprehensive medical team, the Amazon Virtual Medical Team (AVMT), which provided medical support using telemedicine. The AVMT, a multinational volunteer group of specialists, physicians, and telemedicine experts, provided medical support 24/7 in some of the most remote, dangerous, basin. The AVMT was directed basin. The AVMT was directed by Dr. Rifat Latifi and expedition team physician, Dr. Mateja de Leonni Stanonik, who was aboard the boat during the entire expedition. The expedition provided a unique opportunity to promote telemedicine and e-health in over 17 communities in the Amazon basin.

Implementation and evaluation of a low-cost telemedicine station in the remote Ecuadorian rainforest.

A clinical workstation was developed to provide basic telemedicine services in a medical clinic in rural Ecuador. The unit cost was less than $1000. The system provided videoconferencing and a Spanish language electronic medical record (EMR) for clinic consultations. All partners participated in the development of the EMR. Over a six-month period, almost all new patient encounters and ultrasound studies were entered into the EMR. Of 2387 patient encounters, 572 were recorded in electronic format and 80% were transmitted over the Internet for consultation. Four hundred and eight ultrasound studies were filed with the EMR and 90% were transmitted over the Internet for shared evaluation. During the six months of the study, there were no serious software or hardware problems. The doctor in Ecuador was initially trained at the laboratory in the USA. The two sites were in contact by email almost daily. Without such interaction, the performance of the software and hardware would probably have been worse. When a structured programme of instruction, protocols, EMR and technology support is in place, telemedicine can support remote rural practice.

Telemedicine and electronic health information for clinical continuity in a mobile surgery program.

INTRODUCTION: An intermittent surgical services program in rural Ecuador was able to benefit from close collaboration between surgeons and primary care physicians through the use of telemedicine technologies. METHODS: Inexpensive telemedicine workstations capable of patient documentation, imaging, and video-conferencing at extremely low bandwidth were established in collaborative primary care sites in rural Ecuador. Patients were screened for intermittent surgical services by primary caregivers according to the surgeons' guidelines. Real-time and store-and-forward telemedicine allowed appropriate collaborative, informed decision-making. Surgery was performed, and postoperative care was similarly handled by on-site, familiar primary caregivers. RESULTS: To date, this system has been used in more than 124 patient encounters (74 preoperative and 50 postoperative visits). The system allowed advance screening of patients on the part of the surgeons, leading to cancellations for 9 patients. Postoperatively, the system allowed 100% concurrence in postoperative diagnoses between the primary caregivers and the surgeons. CONCLUSIONS: Inexpensive, low-bandwidth telemedicine solutions can support intermittent surgical services by providing patients to have contact with specialist care through their familiar, local primary caregivers.

Remote anesthetic monitoring using satellite telecommunications and the Internet.

Remote collaboration for anesthesia requires considerable sharing of physiologic data, audio, and images on a consistent data platform. A low-bandwidth connection between Ecuador and the United States supported effective joint management of operative plan, airway, intraoperative decisions, and recovery. Transmission with a 64-Kbps InMarSat satellite telephone (Thrane & Thrane, Denmark) connection from hospitals in Macas and Sucúa, Ecuador, to Richmond, Virginia, included preoperative patient evaluations, video of endotracheal intubations, electrocardiogram waveforms, pulse oximetry measurements, arterial blood pressure readings, capnography readings, and auscultation of breath sounds.

Intermittent and mobile surgical services: logistics and outcomes.

A program of intermittent surgical services utilized a mobile facility to support multiple primary care sites in Ecuador. The fiscal and clinical outcomes of the program were analyzed. From 1994 to 2003 the mobile program responded to requests from 15 of 22 provinces of Ecuador for surgical care. The sites served could not offer permanent surgical care. Criteria for inclusion and follow-up were set. Medical records were kept in accordance with standards of the Ministry of Health. Standards of care and critical care pathways were instituted. The program had a permanent staff supplemented by volunteers. Cases were recorded and outcomes noted with respect to complications. The cost of the surgical aspect of the program was entirely covered by a foundation through donations and public service contracts. Financial records of the foundation were reviewed and the costs analyzed. A total of 4545 operations were done largely in general surgery specialties. The program made 40 to 50 excursions each year and proved to be a stable element of medical care delivery. There were no deaths, four major complications, and three minor complications. The cost per operation was less than $100. Comparison to U.S. and international volunteer organizations are reported. This program of intermittent mobile surgical services in coordination with fixed primary care constitutes a sustainable, high quality clinical program fully integrated into existing care of a national health ministry. In-country resources may provide greatly enhanced services at low cost and should be considered as an alternative.

Low-bandwidth telemedicine for pre- and postoperative evaluation in mobile surgical services.

Low-bandwidth telemedicine was used for the pre- and postoperative evaluation of patients treated by a mobile surgery service in remote Ecuador. Realtime and store-and-forward telemedicine was employed, using PCs connected via the ordinary telephone network. Between February 2002 and July 2003, 144 patients were studied preoperatively and 50 postoperatively. It was possible to establish 20 satisfactory preoperative realtime connections, which allowed good-quality, simultaneous audiovisual transmission. Thus, there were 124 preoperative assessments done by store-and-forward telemedicine and 50 postoperative assessments. Diagnoses and management plans made by a surgeon using telemedicine were compared with those made independently by a second surgeon, who saw the patient face to face. Due to poor quality of the transmitted images, 43 patients were excluded from the preoperative study and 13 from the postoperative study. In the 101 preoperative evaluations, there was agreement in 78 cases (77%); in the 37 postoperative evaluations, there was agreement in 36 cases (97%). Telemedicine may reduce the time required on site for preoperative planning, and may provide reliable postoperative surveillance, thus improving the efficiency of mobile surgery services.

Acquisition and evaluation of radiography images by digital camera.

To determine applicability of low-cost digital imaging for different radiographic modalities used in consultations from remote areas of the Ecuadorian rainforest with limited resources, both medical and financial. Low-cost digital imaging, consisting of hand-held digital cameras, was used for image capture at a remote location. Diagnostic radiographic images were captured in Ecuador by digital camera and transmitted to a password-protected File Transfer Protocol (FTP) server at VCU Medical Center in Richmond, Virginia, using standard Internet connectivity with standard security. After capture and subsequent transfer of images via low-bandwidth Internet connections, attending radiologists in the United States compared diagnoses to those from Ecuador to evaluate quality of image transfer. Corroborative diagnoses were obtained with the digital camera images for greater than 90% of the plain film and computed tomography studies. Ultrasound (U/S) studies demonstrated only 56% corroboration. Images of radiographs captured utilizing commercially available digital cameras can provide quality sufficient for expert consultation for many plain film studies for remote, underserved areas without access to advanced modalities.

Case report of remote anesthetic monitoring using telemedicine.

UNLABELLED: We report a case supporting the use of telecommunications technology from a remote location to monitor anesthetic events. Vital signs, data, and video were transmitted from surgery conducted in the remote Amazonian rainforests of Ecuador to Richmond, VA. This application of telemedicine technologies makes available expert advice from remote locations during surgical procedures. IMPLICATIONS: This study validates the use of telecommunications technology from a remote location to monitor an anesthetic event. This type of work makes expert advice available during surgical procedures.

Snakebites in the rainforests of Ecuador.

Epidemiologic information about snakebites in Ecuador is scarce. Snakebites are more common in the lowlands east of the Andes, in the Amazon basin. In the present study, a retrospective review of all ( n = 142) snakebite admissions to Hospital Pio XII, a regional health center/hospital in the canton of Sucúa, Morona Santiago, Ecuador was carried out between the years of 1996 and 2000. Bites occurred more frequently during the months of March to May. The largest group of patients were in the 15- to 49-year-old range (52.5%), and agricultural workers were the most affected of all patients by occupation (> 40%). In most cases of snakebite, patients could not identify the type of snake that had bitten them. A small number of patients ( n = 60, 42.3%) received some type of treatment prior to arrival at the hospital. Bites occurred most frequently on the left lower extremity (31.7%). Typical symptoms included pain and local edema at the snakebite site; generalized symptoms such as fever, nausea, and vomiting were less frequent. Most patients (almost 90%) received antivenin during hospitalization in addition to supportive care. The mean hospital stay was 4.3 days. More than 90% of all 142 patients recovered, about 8% with local abscesses. Mortality was 2.9% and occurred as a result of complications, including renal failure, respiratory failure, and disseminated intravascular coagulation.

Telemedicine to integrate intermittent surgical services into primary care.

Assessment 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.
