Microsystems in health care: Part 2. Creating a rich information environment.

BACKGROUND: A rich information environment supports the functioning of the small, functional, frontline units--the microsystems--that provide most health care to most people. Three settings represent case examples of how clinical microsystems use data in everyday practice to provide high-quality and cost-effective care. CASES: At The Spine Center at Dartmouth, Lebanon, New Hampshire, a patient value compass, a one-page health status report, is used to determine if the provided care and services are meeting the patient's needs. In Summit, New Jersey, Overlook Hospital's emergency department (ED) uses uses real-time process monitoring on patient care cycle times, quality and productivity indicator tracking, and patient and customer satisfaction tracking. These data streams create an information pool that is actively used in this ED icrosystem--minute by minute, hourly, daily, weekly, and annually--to analyze performance patterns and spot flaws that require action. The Shock Trauma Intensive Care Unit (STRICU), Intermountain Health Care, Salt Lake City, uses a data system to monitor the "wired" patient remotely and share information at any time in real time. Staff can complete shift reports in 10 minutes. DISCUSSION: Information exchange is the interface that connects staff to patients and staff to staff within the microsystem; microsystem to microsystem; and microsystem to macro-organization.

The role of nurses in installing telehealth technology in the home.

Home telehealth involves the use of video conferencing or remote monitoring equipment in patients' homes. The installation of hardware and training of patients has historically been performed by nurses, typically RNs. This article examines the experience of RNs as telehealth installers in the Informatics for Diabetes Education and Telemedicine (IDEATel) project, where RNs were responsible for the installation of the Home Telemedicine Units (HTUs) and for training patients in the use of the HTUs, blood pressure cuffs, and fingerstick glucose meters. Average installation and training time was 166 minutes (SD 51 min). Structured interviews with RN installers revealed that patient education and training accounted for roughly two thirds of the in-home time. Technology-related problems, especially those related to telecommunications, were the primary cause of installation difficulties. Thematic analysis of installer interviews identified eight major themes and confirmed the importance of both clinical and technical knowledge during the telehealth installation process.

Driving operations with decision support.

Technology has the power to do many things for home care agencies. Paperwork can be streamlined, productivity increased, patients can be monitored remotely. Decision support systems are the next logical step. A decision support system manages and organizes large amounts of data to assist managers in business decision-making. For the home care world, decision support systems help make sense of the wealth of data that agencies generate in response to Outcome and Assessment Information Set forms and prospective payment system claims.

Recent advances in home infant apnea monitoring.

Appropriate and effective nursing intervention is an essential element in determining how the family responds to the monitor in the home. Accurate assessment of the family system and dynamics provides the basis for a plan of care. The family's and infant's specific needs must be addressed. Careful implementation of the plan allows for changes and unexpected outcomes. Frequent evaluation of monitoring is necessary to determine if a change in the plan of care is needed. Recent changes in home apnea monitoring technology are rapidly altering the care of infants at risk for apnea and SIDS. The advent of the documented or recording monitor has the potential to demystify the events occurring while the infant is being monitored. Parents can get answers about their infant as quickly as a telephone call. The clinician can differentiate between a true and a false alarm and reassure the parents accordingly. Documenting false events and shallow-breathing alarms will potentially reduce the duration of monitoring, decreasing costs to the entire health care system. Documented monitoring is a valuable tool for nurses. For the staff nurse, clinical observation can be validated through trending and print out of events can be done at the bedside. For the advanced practice nurse, management of care can become more efficient through remote monitoring via modem. Patient teaching can be followed with immediate feedback. Monitors may assist in allaying anxiety in families who have lost children to SIDS or had an unexpected death in a previous sibling. Families may feel less anxious about having an "at risk" child in the home if the events are continuously being recorded. Length of hospital stay may decrease initially, with fewer rehospitalizations. Nursing research in these areas is necessary. Evaluating events occurring in the home may also help shed light on the enigma of SIDS. Several SIDS deaths have been recorded on documented monitors. If we can pinpoint exactly what takes place prior to and immediately after a SIDS episode, the enigma that has had physicians puzzled for so long may finally begin to unravel.

An intelligent remote monitoring system for artificial heart.

A web-based database system for intelligent remote monitoring of an artificial heart has been developed. It is important for patients with an artificial heart implant to be discharged from the hospital after an appropriate stabilization period for better recovery and quality of life. Reliable continuous remote monitoring systems for these patients with life support devices are gaining practical meaning. The authors have developed a remote monitoring system for this purpose that consists of a portable/desktop monitoring terminal, a database for continuous recording of patient and device status, a web-based data access system with which clinicians can access real-time patient and device status data and past history data, and an intelligent diagnosis algorithm module that noninvasively estimates blood pump output and makes automatic classification of the device status. The system has been tested with data generation emulators installed on remote sites for simulation study, and in two cases of animal experiments conducted at remote facilities. The system showed acceptable functionality and reliability. The intelligence algorithm also showed acceptable practicality in an application to animal experiment data.

Ambulatory monitoring for chronic cardiac and pulmonary patients.

In the Greek pilot of the e-Vital project, remote telemedicine services are provided to chronic cardiac and pulmonary patients who are not confined to a hospital (i.e. receiving home/ambulatory health care) with the aim of exploring the dynamics of interactive continuous chronic patient monitoring, particularly focusing on the impact on patient's quality of life, the patient's active involvement in their own care and according impact on the overall quality of healthcare provision, as well as the benefits for healthcare providers (time management, patient management, savings, etc). The current trial in progress validates the business potential of remote monitoring services and demonstrates the technical environment that enables patient-doctor interaction regardless of location and the according communication modes and protocols. The domain for applying the envisaged service is the private healthcare sector and the users groups include individual chronic patients with cardiac and pulmonary diseases. So far, from the patient's point of view, the service mainly appeals to patients with arrhythmias due to lightweight technology and easy processes involved in the transmission of 1-lead ECG. Asthma and COPD patients are also enthusiastic, as they can receive doctor advice in real time. From the health professional's point of view the service has real added value in the fields of diagnosis, prevention, monitoring and follow up. In the case of asthma and COPD the value of the service in diagnosis is even more apparent as these patients may be asymptomatic, when they visit their doctor and have exacerbations when they are at home. e-Vital in this case ensures that the healthcare professional will acquire the complete image of the patient condition. Finally, the experiences gained so far indicate that e-Vital could be particularly efficient in isolated areas, with shortage of experienced scientific personnel.

Home care artificial heart monitoring system via internet.

The availability of a remote management system, which provides both physiological-related information about the patient and device-related information about the implanted device, would be helpful during in vivo experiments or clinical trials involving artificial heart implantation. In order to be able to monitor the course of the in vivo experiment continuously regardless of the patient's location, an internet-based remote monitoring system was developed, which can monitor physiological-related information such as pressure (AoP, LAP, RAP, PAP) and flow data, as well as device-related information such as current, direction and pump operating conditions. The home care artificial heart monitoring system which we developed consists of four main components, which are the transcutaneous information transmission system (TITS), local monitoring station (LMS), data server station (DSS), and client monitoring station (CMS). The device-related information and physiological-related information can be transmitted in real time from a patient in a remote non-clinical environment to the specialist situated in a clinic depending on the current capabilities and availability of the internet. The local monitoring station situated at the remote site is composed of a data acquisition and preprocessing unit connected to a computer via its RS-232 port, and which communicate using a Java-based client-server architecture. The remote monitoring system so developed was used during an in vivo experiment of the artificial heart implantation for 2 months and performed successfully according to design specifications.

Transtelephone pacemaker monitoring: five years later.

Six hundred nineteen patients have been followed by remote monitoring of pacemaker function using ECG and rate or rate alone; 278 of 280 have had battery exhaustion or electronic failure demonstrated. Ten percent of exhausted pacemakers failed prior to the average longevity of the particular model, and 32% (89 of 280) exceeded 36 months' longevity; of these, 13% (37 of 280) lasted more than 40 months and 4.6% (13 of 280) exceeded 50 months. The error rate is 0.7% (2 of 280). With pulse generator longevity increasing, monitoring is done less frequently during the first 2 years, then calls are made weekly after 24 months.

Virtual reality-based orthopedic telerehabilitation.

Rehabilitation interventions in remote areas are problematic because of distance and available resources. Orthopedic impairments acquired by individuals in remote areas can then lead to permanent disabilities/loss of function because of lack of appropriate rehabilitation. A system being developed by Rutgers and Stanford Universities provides therapy at the patient's home, with remote monitoring and periodic re-assessment. This telerehabilitation system uses virtual reality and haptic interfaces, and a pair of networked PCs. It is intended for rehabilitation of patients with hand, elbow, knee and ankle impairments. Data from the first patient treated with the telerehabilitation system is encouraging.

Monitoring monitors.

A centralized, remote alarm system was implemented to alert nursing personnel when patient monitors located in isolation rooms go into alarm. The design includes a method of confirming the ON/OFF status of individual monitors to avoid operator error. This system utilizes low-cost individual patient monitors and includes interface devices, an alarm panel, and indicator panels. The design logic is based on the need for nursing personnel to also be alerted in the event of any abnormality associated with the patient monitors, the alarm panel itself, or with the interconnections. The system will also accommodate infusion pumps, respirators, or any other devices equipped with a remote alarm (nurse call) output.

System of telemedicine services designed for family doctors' practices.

The main goal of the most European telemedicine programs is to increase access to emergency and primary care; however, telemedicine presents both profound opportunities and challenges to general practice/family medicine. The aim of this project is to develop and demonstrate a regional primary care teleconsulting system in Poland linking an academic family medicine center and 10 family doctors' practices (both urban and rural) within a range of 100-200 km, serving a local population of 25,000 individuals. It is designed to support real-time consultations among health care providers via a computer network, provide secure access to multimedia patient records, and facilitate an innovative home monitoring and remote care from doctors to their patients. The entire process (planned for 3 years) includes: selecting the best technology (i.e., teletransmission system, communication protocols, etc.) and equipment; preparing the assumptions and conditions for formats and transmission rates; analysis of the existing techniques of compression and preparing own specific solution; finding an optimal infrastructure (i.e., equipment and communication configuration); implementing the system; evaluation of the medical, economic, organizational, and sociological aspects of the system (i.e., accessibility to primary health care, cost feasibility and cost-effectiveness of telemedicine services, quality of care assessment, etc.). The project offers the potential to improve: access to high-quality primary health care; the patient-physician bond and the attending physician's level of confidence; education of family doctors; use of expensive resources; and a convenient mode of delivering medical services to the patient.

Transtelephonic electrocardiographic monitoring of cardiac rehabilitation exercise sessions in coronary artery disease.

Transtelephonic monitoring of a single-lead electrocardiogram and on-demand 2-way voice communication were accomplished at 1,865 exercise sessions for 67 cardiac patients. Exercise sessions occurred either at the patients' homes or at remote hospital sites and began an average of 25 or 14 weeks, respectively, after hospital dismissal. Monitoring centers provided experienced nurses to direct all exercise sessions. The transtelephonic monitoring equipment was reliable with only one instance of system failure observed. A broad spectrum of patients with coronary artery disease, including some classified at higher risk, participated in the program. Patients exercised with a variety of equipment (cycle ergometer, treadmill, arm ergometer, cross-country ski simulator, combination arm-leg cycle ergometer, rowing machine), for 30 to 50 minutes, 1 to 3 times each week. No medical emergencies occurred, although 18 specific problems were discovered that led to further evaluation or change in the medical program of specific patients. Transtelephonic monitoring of cardiac rehabilitation exercise sessions at home and at remote hospitals appears safe and is attractive because not all patients have access to supervised exercise programs; this exercise assessment helps to maximally use highly trained cardiac rehabilitation personnel.

Usability of the remote console for virtual reality telerehabilitation: formative evaluation.

The Remote Console (ReCon) is a telerehabilitation application that allows therapists to remotely communicate with patients while monitoring and controlling their virtual rehabilitation exercises. It provides therapists visual feedback of patients' movements, their exercise simulations replicated in real time and with tools to conduct training without a face-to-face session. The Recon underwent a formative evaluation (a type of usability engineering methodology) used to refine its design. Five physical therapists from different practice settings acted as representative users. During the evaluation, these users made errors related to manipulation and finding and understanding controls. Technical issues with the server and audio communication were identified. These findings were used to fine-tune the ReCon system.

Multimedia telehomecare system using standard TV set.

Nowadays, there are a very large number of patients that need specific health support at home. The deployment of broadband communication networks is making feasible the provision of home care services with a proper quality of service. This paper presents a telehomecare multimedia platform that runs over integrated services digital network and internet protocol using videoconferencing standards H.320 and H.323, and standard TV set for patient interaction. This platform allows online remote monitoring: ECG, heart sound, blood pressure. Usability, affordability, and interoperability were considered for the design and development of its hardware and software components. A first evaluation of technical and usability aspects were carried forward with 52 patients of a private clinic and 10 students in the University. Results show a high rate (mean = 4.33, standard deviation--SD = 1.63 in a five-points Likert scale) in the global perception of users on the quality of images, voice, and feeling of virtual presence.

Shared virtual environments for telerehabilitation.

Current VR telerehabilitation systems use offline remote monitoring from the clinic and patient-therapist videoconferencing. Such "store and forward" and video-based systems cannot implement medical services involving patient therapist direct interaction. Real-time telerehabilitation applications (including remote therapy) can be developed using a shared Virtual Environment (VE) architecture. We developed a two-user shared VE for hand telerehabilitation. Each site has a telerehabilitation workstation with a videocamera and a Rutgers Master II (RMII) force feedback glove. Each user can control a virtual hand and interact hapticly with virtual objects. Simulated physical interactions between therapist and patient are implemented using hand force feedback. The therapist's graphic interface contains several virtual panels, which allow control over the rehabilitation process. These controls start a videoconferencing session, collect patient data, or apply therapy. Several experimental telerehabilitation scenarios were successfully tested on a LAN. A Web-based approach to "real-time" patient telemonitoring--the monitoring portal for hand telerehabilitation--was also developed. The therapist interface is implemented as a Java3D applet that monitors patient hand movement. The monitoring portal gives real-time performance on off-the-shelf desktop workstations.
