A two-way messaging system to enhance antiretroviral adherence.
(65/1282)
Failure to adhere to complex antiretroviral regimens can lead to resistance and treatment failure among HIV-positive persons. In this study of the feasibility of an automated two-way messaging system to improve adherence, participants received multiple short daily messages designed to remind, educate, encourage adherence, and solicit responses concerning side effects and self-reported adherence. Twenty-five participants remained in the study for a median of 208 days, receiving 17,440 messages and replying to 14,677 (84%). Participants reported missing one or more doses on 36% of 743 queries and reported medication side effects on 26% of 729 queries. Participants expressed high satisfaction with the messaging system and reported that it helped with medication adherence. The study suggests that it is feasible to use an automated wireless two-way messaging system to communicate with HIV-positive patients over an extended period of time. (+info)
Medicare program; revisions to payment policies under the physician fee schedule for calendar year 2003 and inclusion of registered nurses in the personnel provision of the critical access hospital emergency services requirement for frontier areas and remote locations. Final rule with comment period.
(66/1282)
This final rule with comment period refines the resource-based practice expense relative value units (RVUs) and makes other changes to Medicare Part B payment policy. In addition, as required by statute, we are announcing the physician fee schedule update for CY 2003. The update to the physician fee schedule occurs as a result of a calculation methodology specified by law. That law required the Department to set annual updates based in part on estimates of several factors. Although subsequent after-the-fact data indicate that actual increases were different to some degree from earlier estimates, the law does not permit those estimates to be revised. A subsequent law required estimates to be revised for FY 2000 and beyond. Although we have exhaustively examined opportunities for a different interpretation of law that would allow us to correct the flaw in the formula administratively, current law does not permit such an interpretation. Accordingly, without Congressional action to address the current legal framework, the Department is compelled to announce herein a physician fee schedule update for CY 2003 of -4.4 percent. Because the Department would adopt a change in the formula that determines the physician update if the law permitted it, we have examined how proper adjustments to past data could result in a positive update. The Department believes that revisions of estimates used to establish the sustainable growth rates (SGR) for fiscal years (FY) 1998 and 1999 and Medicare volume performance standards (MVPS) for 1990-1996 would, under present calculations, result in a positive update. The Department intends to work closely with Congress to develop legislation that could permit a positive update, and hopes that such legislation can be passed before the negative update takes effect. Because the Department wishes to change the update promptly in the event that Congress provides the Department legal authority to do so, we are requesting comments regarding how physician fee schedule rates could and should be recalculated prospectively in the event that Congress provides the Department with legal authority to revise estimates used to establish the sustainable growth rates (SGR) and for 1998 and 1999 and the NVPS for 1990-1996. The other policy changes concern: the pricing of the technical component for positron emission tomography (PET) scans, Medicare qualifications for clinical nurse specialists, a process to add or delete services to the definition of telehealth, the definition for ZZZ global periods, global period for surface radiation, and an endoscopic base for urology codes. In addition, this rule updates the codes subject to physician self-referral prohibitions. We are expanding the definition of a screening fecal-occult blood test and are modifying our regulations to expand coverage for additional colorectal cancer screening tests through our national coverage determination process. We also make revisions to the sustainable growth rate, the anesthesia conversion factor, and the work values for some gastroenterologic services. We are making these changes to ensure that our payment systems are updated to reflect changes in medical practice and the relative value of services. This final rule also clarifies the enrollment of physical and occupational therapists as therapists in private practice and clarifies the policy regarding services and supplies incident to a physician's professional services. In addition, this final rule discusses physical and occupational therapy payment caps and makes technical changes to the definition of outpatient rehabilitation services. In addition, we are finalizing the calendar year (CY) 2002 interim RVUs and are issuing interim RVUs for new and revised procedure codes for calendar year (CY) 2003. As required by the statute, we are announcing that the physician fee schedule update for CY 2003 is -4.4 percent, the initial estimate of the sustainable growth rate for CY 2003 is 7.6 percent, and the conversion factor for CY 2003 is $34.5920. This final rule will also allow registered nurses (RNs) to provide emergency care in certain critical access hospitals (CAHs) in frontier areas (an area with fewer than six residents per square mile) or remote locations (locations designated in a State's rural health plan that we have approved.) This policy applies if the State, following consultation with the State Boards of Medicine and Nursing, and in accordance with State law, requests that RNs be included, along with a doctor of medicine or osteopathy, a physician's assistant, or a nurse practitioner with training or experience in emergency care, as personnel authorized to provide emergency services in CAHs in frontier areas or remote locations.

Integration of advanced technologies to enhance problem-based learning over distance: Project TOUCH.
(67/1282)
Distance education delivery has increased dramatically in recent years as a result of the rapid advancement of communication technology. The National Computational Science Alliance's Access Grid represents a significant advancement in communication technology with potential for distance medical education. The purpose of this study is to provide an overview of the TOUCH project (Telehealth Outreach for Unified Community Health; http://hsc.unm.edu/touch) with special emphasis on the process of problem-based learning case development for distribution over the Access Grid. The objective of the TOUCH project is to use emerging Internet-based technology to overcome geographic barriers for delivery of tutorial sessions to medical students pursuing rotations at remote sites. The TOUCH project also is aimed at developing a patient simulation engine and an immersive virtual reality environment to achieve a realistic health care scenario enhancing the learning experience. A traumatic head injury case is developed and distributed over the Access Grid as a demonstration of the TOUCH system. Project TOUCH serves as an example of a computer-based learning system for developing and implementing problem-based learning cases within the medical curriculum, but this system should be easily applied to other educational environments and disciplines involving functional and clinical anatomy. Future phases will explore PC versions of the TOUCH cases for increased distribution. (+info)
Virtual patient simulator for distributed collaborative medical education.
(68/1282)
Project TOUCH (Telehealth Outreach for Unified Community Health; http://hsc.unm.edu/touch) investigates the feasibility of using advanced technologies to enhance education in an innovative problem-based learning format currently being used in medical school curricula, applying specific clinical case models, and deploying to remote sites/workstations. The University of New Mexico's School of Medicine and the John A. Burns School of Medicine at the University of Hawai'i face similar health care challenges in providing and delivering services and training to remote and rural areas. Recognizing that health care needs are local and require local solutions, both states are committed to improving health care delivery to their unique populations by sharing information and experiences through emerging telehealth technologies by using high-performance computing and communications resources. The purpose of this study is to describe the deployment of a problem-based learning case distributed over the National Computational Science Alliance's Access Grid. Emphasis is placed on the underlying technical components of the TOUCH project, including the virtual reality development tool Flatland, the artificial intelligence-based simulation engine, the Access Grid, high-performance computing platforms, and the software that connects them all. In addition, educational and technical challenges for Project TOUCH are identified. (+info)
Telehealth technologies and applications for terrorism response: a report of the 2002 coastal North Carolina domestic preparedness training exercise.
(69/1282)
Effective response to natural or man-made disasters (i.e., terrorism) is predicated on the ability to communicate among the many organizations involved. Disaster response exercises enable disaster planners and responders to test procedures and technologies and incorporate the lessons learned from past disasters or exercises. On May 31 and June 1, 2002, one such exercise event took place at the Camp Lejeune Marine Corps Base in Jacksonville, North Carolina. During the exercise, East Carolina University tested: (1) in-place Telehealth networks and (2) rapidly deployable communications, networking, and data collection technologies such as satellite communications, local wireless networking, on-scene video, and clinical and environmental data acquisition and telemetry. Exercise participants included local, county, state, and military emergency medical services (EMS), emergency management, specialized response units, and local fire and police units. The technologies and operations concepts tested at the exercise and recommendations for using telehealth to improve disaster response are described. (+info)
Integration of telemedicine in graduate medical informatics education.
(70/1282)
An essential part of health informatics is telemedicine, the use of advanced telecommunications technologies to bridge distance and support health care delivery and education. This report discusses the integration of telemedicine into a medical informatics curriculum and, specifically, a framework for a telemedicine course. Within this framework, the objectives and exit competencies are presented and course sections are described: definitions, introduction to technical aspects of telemedicine, evolution of telemedicine and its impact on health care delivery, success and failure factors, and legal and ethical issues. The emphasis is on literature review tools, practical exposure to products and applications, and problem-based learning. Given the rapid advances in the telecommunication field, keeping the course material up to date becomes a challenge for the instructor who at the same time aims to equip students with the knowledge and tools they will need in their future role as decision makers to detect a need for, design, implement, maintain, or evaluate a telemedicine application.

Multi-purpose HealthCare Telemedicine Systems with mobile communication link support.
(71/1282)
The provision of effective emergency telemedicine and home monitoring solutions are the major fields of interest discussed in this study. Ambulances, Rural Health Centers (RHC) or other remote health location such as Ships navigating in wide seas are common examples of possible emergency sites, while critical care telemetry and telemedicine home follow-ups are important issues of telemonitoring. In order to support the above different growing application fields we created a combined real-time and store and forward facility that consists of a base unit and a telemedicine (mobile) unit. This integrated system: can be used when handling emergency cases in ambulances, RHC or ships by using a mobile telemedicine unit at the emergency site and a base unit at the hospital-expert's site, enhances intensive health care provision by giving a mobile base unit to the ICU doctor while the telemedicine unit remains at the ICU patient site and enables home telemonitoring, by installing the telemedicine unit at the patient's home while the base unit remains at the physician's office or hospital. The system allows the transmission of vital biosignals (3-12 lead ECG, SPO2, NIBP, IBP, Temp) and still images of the patient. The transmission is performed through GSM mobile telecommunication network, through satellite links (where GSM is not available) or through Plain Old Telephony Systems (POTS) where available. Using this device a specialist doctor can telematically "move" to the patient's site and instruct unspecialized personnel when handling an emergency or telemonitoring case. Due to the need of storing and archiving of all data interchanged during the telemedicine sessions, we have equipped the consultation site with a multimedia database able to store and manage the data collected by the system. The performance of the system has been technically tested over several telecommunication means; in addition the system has been clinically validated in three different countries using a standardized medical protocol.

Telerobotic laparoscopic repair of incisional ventral hernias using intraperitoneal prosthetic mesh.
(72/1282)
Laparoscopic ventral hernia repair shortens the length of hospital stay and achieves low rates of hernia recurrence. The inherent difficulties of performing advanced laparoscopy operations, however, have limited the adoption of this technique by many surgeons. We hypothesized that the virtual operative field and hand-like instruments of a telerobotic surgical system could overcome these limitations. We present herein the first 2 reported cases of telerobotic laparoscopic ventral hernia repair with mesh. The operations were accomplished with the da Vinci telerobotic surgical system. The hernia defects were repaired with dual-sided, expanded polytetrafluoroethylene (ePTFE) mesh. The mesh was secured in place with 8 sutures that were passed through the abdominal wall, and 5-mm surgical tacks were placed around the circumference of the mesh. The 2 operations were accomplished with total operative times of 120 and 135 minutes and total operating room times of 166 and 180 minutes, respectively. The patients were discharged home on postoperative days 1 and 4. The surgeon sat in an ergonomically comfortable position at a computer console that was remote from the patient. Immersion of the surgeon within the 3-dimensional virtual operative field expedited each stage of these procedures. The articulation of the wristed telerobotic instruments greatly facilitated reaching the anterior abdominal cavity near the abdominal wall. This report indicates that telerobotic laparoscopic ventral hernia repair is feasible and suggests that telepresence technology facilitates this procedure. (+info)
