An overview of telemedicine: the virtual gaze of health care in the next century

This article considers the role of telemedicine in the production of biomedical health care using three specific theoretical constructs as lenses through which to examine this phenomenon: (1) Foucault's medical "gaze"; (2) the political economy of health; and (3) deterritorialization and multisite ethnography. This examination focuses first on the changing corporate structure of health care and changing political attitudes toward telemedicine. Second, it documents the current use of telemedicine in prisons, the military, and in cross-cultural settings. Third, it discusses responses to telemedicine of individual physicians, health care staff, and patients, finding that these responses are broadly conditioned by an individual's mode of articulation with biomedical institutions and that they are mediated by personal experience.     

Development of a telemedicine program: a review of 1,000 videoconferencing consultations

Objective To examine the financial and organizational characteristics, demand for services, and satisfaction outcomes of a growing telemedicine program serving both urban or suburban and rural populations. Design Retrospective review of 1,000 consecutive telemedicine consultations in the University of California (UC) Davis Telemedicine Program. Setting Telemedicine videoconferencing units, used to integrate care in the UC Davis Health System among the UC Davis Medical Center and several urban or suburban primary care clinics, rural hospitals, and clinic affiliates. Subjects A total of 657 consecutive patients who consented to a telemedicine consultation. Main outcome measures Demographic information about the patient population, the rural and urban or suburban clinics, the types of specialty consultations, and telemedicine equipment used in the UC Davis Health System. Patient and physician satisfaction were measured on a 5-point Likert scale. Results Patients and primary care physicians reported high levels of satisfaction. Rural clinics requested more and a greater variety of specialist consultations than urban or suburban clinics. Conclusion Although referring physicians and patients indicate a high level of satisfaction with telemedicine services and insurers are negotiating reimbursement policies, additional research must investigate the reasons why some payers, patients, and providers resist participation in these services.     

The use of information technology in improving medical performance. Part II. Physician-support tools

Increasing data from a few sites demonstrate that information technologies can improve physician decision making and clinical effectiveness. For example, computer-based physician order entry systems, automated laboratory alert systems, and artificial neural networks have demonstrated significant reductions in medical errors. In addition, Internet services to disseminate new knowledge and safety alerts to physicians more rationally and effectively are rapidly developing, and telemedicine to improve rural access to specialty services is undergoing substantial growth. However, even technologies demonstrated to yield beneficial effects have not yet achieved widespread adoption, though the pace of change appears to be increasing as the Internet takes hold. Scientific evaluation of many technologies is also lacking, and the dangers of some of these technologies may be underappreciated. Research on the effects of specific technologies should be a priority. Policies should be developed to press information technology companies, such as pharmaceutical and medical device manufacturers, to recognize the importance of clinical evaluation. Research could also analyze the characteristics of effective technologies and of physicians and organizations who implement these technologies effectively.     

What are the facts concerning the number of residency positions in Canada?

Some physicians think the current squeeze facing postgraduate medical education was caused by cuts in the number of residency positions. The authors consulted the Canadian Post-MD Education Registry database to determine the actual state of postgraduate training opportunities and to correct erroneous views that may be affecting the debate over training positions. The danger, they say, is that misinformation may lead to inappropriate strategies for dealing with current challenges.     

Frustrated residents worry as they look toward an uncertain future.

Frustrated, disheartened and angry that most provinces have introduced disincentive measures that target young physicians, today''s residents are discouraged and uncertain about their future. Not only will the medical profession lose because of this situation, the residents say, but so will patients who are deprived of new ideas and physicians with the most current training. Nancy Robb examines the mood of the country''s physicians-in-waiting.     

Childproof caps open Pandora's box

This fall Ontario braced for possible strikes by public servants and teachers. A year earlier, the province''s physicians were preparing their own job action. Walkouts by physicians, which have not been uncommon since the introduction of medicare, create two camps. In one are physicians who say legal job actions are ethical and often improve health care for patients. In the other are some doctors and ethicists who question whether doctors have an ethical right to withdraw services, even if it is legal to do so. Nicole Baer interviewed members of both camps.     

MDs remain sceptical as chelation therapy goes mainstream in Saskatchewan

The College of Physicians and Surgeons of Saskatchewan recently agreed to allow physicians to administer chelation therapy. Supporters, relying on anecdotal evidence, say it works wonders in overcoming heart disease, but many physicians remain profoundly sceptical. In Saskatchewan, the college decision has proved popular with patients but has drawn an angry reaction from doctors.     

Telemedicine in plastic surgery: E-consult the attending surgeon

Telemedicine has evolved into a valuable but underused resource for the delivery of health care to patients at a distance, particularly where patient transport is impractical, expensive, complicated, and/or urgent. Today, over 250,000 telemedicine consults are generated annually, involving various specialties in both military and civilian health delivery systems. The ability to evaluate and triage plastic surgery patients through the use of telemedicine has not been widely explored. We have designed, developed, and tested a "store-and-forward" solution at UMass Memorial Hospital and Beth Israel Deaconess Hospital whereby the plastic surgery residents who responded to a consult request transmitted digital photographs by means of the Internet to the attending physician on call. The customary telephone call between resident and attending physician benefited from the additional photographic data, and patient management resulted in a clear, concise, and unambiguous treatment plan. The initial management suggested by the resident was modified on some occasions, particularly with complex problems. The use of digital images was especially helpful for evaluation of radiographs and complex wounds of the hand and face. The solution proved to be very valuable for both attending physicians and residents in plastic surgery. The photographs provide rich detail and resolution comparable to high-quality prints. The mechanics of obtaining images and the process of sending them electronically was readily mastered. Images reached their destination in only a few minutes over standard telephone lines. No problems were encountered while sending or viewing images on Macintosh or Windows platforms. Determining course of action with a complete clinical history now includes a level of visual detail previously not available. As this application expands into wider use, data integrity and safety will have to be more formally secured and monitored. Our model of telemedicine has broad-reaching ramifications for the improvement of health-care delivery locally, nationally, and internationally.     

Fraud worries insurance companies but should concern physicians too,industry says

The amount of insurance fraud is increasing in Canada. This should worry physicians, because all personal-injury claims must be substantiated by a medical certificate. The vast majority of physicians are honest and ethical, fraud investigators say, but some are being duped as patients scheme to cheat the insurance industry. In one sensational auto-insurance-fraud case, some Ontario physicians are being investigated about possible involvement in a self-referral scheme. Nicole Baer looks at insurance fraud and the challenges it poses for doctors.     

Canadians pay for harsh economic policies with their health,physicians warn.

Canada''s fiscal policies are damaging the health of Canadians, two physicians told a conference that examined globalization''s impact on the country. Near-record unemployment levels and the recent recession have forced 41% of families in which the parents are 30 or younger to live below the poverty level; more than 21% of Canadian children are also considered to live in poverty. The impact tight fiscal policies have on health and well-being are enormous, say the dean of medicine at the University of Western Ontario and the chair of the Canadian Institute of Child Health.     

Telemedicine for Hip Preservation Patients: Access,Ability and Preference

BackgroundRecent events have resulted in rapid rises in the use of telemedicine in orthopaedic surgery, despite limited evidence regarding patient preferences or concerns. The purpose of this study is to determine access to and, ability to use telemedicine technology in an adult hip preservation patient population, as well as determine associations with patient characteristics. Additionally, we seek to understand patients’ perceived benefits, risks and preferences of telemedicine.MethodsWe performed a cross-sectional survey administered on patients scheduled to undergo joint preservation surgery by one of three surgeons at a single academic institution. Both preoperative and postoperative established patients were included and called for a telephone administered survey if a date of surgery was scheduled between October 1, 2019 and March 30, 2020 and were 18 years or older. The survey had seven sections with 45 questions relating to demographics, technology access, videoconferencing capability, confidence using technology, telehealth experiences, perceptions.Results101 patients completed the survey (48% response rate, 101/212). Overall, 99% of participants reported using the internet, 94% reporting owning a device capable of videoconferencing, and 86% of patients had participated in a video call in the past year. When asked for their preferred method for a physician visit: 79% ranked in-person as their first choice and 16% ranked a videoconference visit as their first choice. Perceived benefits of telemedicine visits included reduced travel to appointments (97% agree) and reduced cost of attending appointments (69% agree). However, patients were concerned that they would not establish the same patient-physician connection (51% agree) and would not receive the same level of care (38% agree) through telemedicine visits versus in person visits.ConclusionThe majority of hip preservation patients have access to and are capable of using the technology required for telemedicine visits. However, patients still prefer to have in person visits over concerns that they will not establish the same patient-physician connection and will not receive the same level of care. Telemedicine visits in hip preservation patients may be most attractive to return patients with an established doctor-patient relationship, particularly those with concerns for long distances of travel and associated costs.Level of Evidence: III     

Visions of our health care future: is a parallel private system the answer?

In this time of spending restraint, arguments for and against a two-tier medical system are common. Proponents say governments can no longer afford to supply all the health care we want and Canadians should have the right to purchase it, just as they purchases other services and commodities. Opponents fear that administrative costs will rise greatly if this happens, the best physicians will leave the public system and public support for medicare will erode. For this article, Charlotte Gray sought opinions on whether a parallel private system is a good option for Canadians to consider.

Point-of-care pathology with miniature microscopes

Advances in optical designs are enabling the development of miniature microscopes that can examine tissue in situ for early anatomic and molecular indicators of disease, in real time, and at cellular resolution. These new devices will lead to major changes in how diseases are detected and managed, driving a shift from today's diagnostic paradigm of biopsy followed by histopathology and recommended therapy, to non-invasive point-of-care diagnosis with possible same-session definitive treatment. This shift may have major implications for the training requirements of future physicians to enable them to interpret real-time in vivo microscopic data, and will also shape the emerging fields of telepathology and telemedicine. Implementation of new technologies into clinical practice is a complex process that requires bridging gaps between clinicians, engineers and scientists. This article provides a forward-looking discussion of these issues, with a focus on malignant and pre-malignant lesions, by first highlighting some of the clinical areas where point-of-care in vivo microscopy could address unmet needs, and then by reviewing the technological challenges that are being addressed, or need to be addressed, for in vivo microscopy to become a standard clinical tool.     

Comparative Effectiveness of Different Forms of Telemedicine for Individuals with Heart Failure (HF): A Systematic Review and Network Meta-Analysis

BackgroundPrevious studies on telemedicine have either focused on its role in the management of chronic diseases in general or examined its effectiveness in comparison to standard post-discharge care. Little has been done to determine the comparative impact of different telemedicine options for a specific population such as individuals with heart failure (HF).LimitationsMuch of the evidence currently available has focused on the comparing either telephone support or telemonitoring with usual care. This has therefore limited our current understanding of how some of the less common forms of telemedicine compare to one another.ConclusionsCompared to usual care, structured telephone support and telemonitoring significantly reduced the odds of deaths and hospitalization due to heart failure. Despite being the most widely studied forms of telemedicine, little has been done to directly compare these two interventions against one another. Further research into their comparative cost-effectiveness is also warranted.     

Systematic review of cost effectiveness studies of telemedicine interventions

ObjectivesTo systematically review cost benefit studies of telemedicine.DesignSystematic review of English language, peer reviewed journal articles.Results557 articles without cost data categorised by topic. 55 articles with data initially categorised by cost variables employed in the study and conclusions. Only 24/55 (44%) studies met quality criteria justifying inclusion in a quality review. 20/24 (83%) restricted to simple cost comparisons. No study used cost utility analysis, the conventional means of establishing the “value for money” that a therapeutic intervention represents. Only 7/24 (29%) studies attempted to explore the level of utilisation that would be needed for telemedicine services to compare favourably with traditionally organised health care. None addressed this question in sufficient detail to adequately answer it. 15/24 (62.5%) of articles reviewed here provided no details of sensitivity analysis, a method all economic analyses should incorporate.ConclusionThere is no good evidence that telemedicine is a cost effective means of delivering health care.

What is already known on this topic

The use of telemedicine has garnered much attention in the past decadeHundreds of articles have been published claiming that telemedicine is cost effectiveHowever, missing from the literature is a synthesis or meta-analysis of these publications

What this study adds

A comprehensive literature search of cost related articles on telemedicine identified more than 600 articles, but only 9% contained any cost benefit dataOnly 4% of these articles met quality criteria justifying inclusion in a formalised quality review, and most of these were small scale, short term, pragmatic evaluations with few generalisable conclusionsThere is little published evidence to confirm whether or not telemedicine is a cost effective alternative to standard healthcare delivery     

Multi-purpose HealthCare Telemedicine Systems with mobile communication link support

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.     

Current experiences with internet telepathology and possible evolution in the next generation of Internet services.

The last five years experience has definitely demonstrated the possible applications of the Internet for telepathology. They may be listed as follows: (a) teleconsultation via multimedia e-mail; (b) teleconsultation via web-based tools; (c) distant education by means of World Wide Web; (d) virtual microscope management through Web and Java interfaces; (e) real-time consultations through Internet-based videoconferencing. Such applications have led to the recognition of some important limits of the Internet, when dealing with telemedicine: (i) no guarantees on the quality of service (QoS); (ii) inadequate security and privacy; (iii) for some countries, low bandwidth and thus low responsiveness for real-time applications. Currently, there are several innovations in the world of the Internet. Different initiatives have been aimed at an amelioration of the Internet protocols, in order to have quality of service, multimedia support, security and other advanced services, together with greater bandwidth. The forthcoming Internet improvements, although induced by electronic commerce, video on demand, and other commercial needs, are of real interest also for telemedicine, because they solve the limits currently slowing down the use of Internet. When such new services will be available, telepathology applications may switch from research to daily practice in a fast way.     

THE MISTREATED CHILD

“The battered child” has recently attracted the attention of physicians and social workers, but despite the fact that inflicted trauma produces characteristic x-ray changes, physicians are often reluctant to admit this cause. The neglected child may be more difficult to diagnose and is probably more common. The most typical example is the infant who is admitted to the hospital for “failure to thrive,” yet gains weight rapidly while away from his parents.The parents of both types of children are likely to be immature and inadequate, but much more study is required before the factors common to these parents are known, to say nothing of the means required for prevention and treatment.When the physician suspects that the parent is causing the difficulties manifested by the child, he should seek the help of a social worker in clarifying the situation and in contacting the appropriate social or legal agency. A greater awareness of the problems of these children should result in more rapid recognition of the condition, the establishment of well-defined methods of handling such cases, and ultimately better legislation to safeguard the child''s rights to a safe and healthy childhood.
