Telemedicine: where it is and where it's going

Adaptation to Virtual Assessment during the COVID-19 Pandemic: Clinical Case Presentation Examination

BACKGROUND

Case presentation assessment is common in both medicine and dentistry and is known under various names depending on the country and institution. It relates mainly to aspects of diagnosis and treatment planning and is considered highly authentic and useful. The COVID-19 pandemic necessitated the movement of this assessment from face-to-face to online. The aim of this investigation was to explore the students' impressions of the two different examination modalities. With this information, a decision on future diets of this examination can be made to accommodate the students' perspectives.

METHODS

Quantitative and qualitative data were gathered using an online, self-administered survey.

RESULTS

The students were split 50/50 regarding which assessment modality they preferred. Overall, they considered the online examination to be fair, and the majority agreed that the online format allowed them to display their knowledge as well as face-to-face.

CONCLUSIONS

The delivery of case presentation examination is possible online. An online case presentation is a fair, useful, and authentic assessment that is appropriate to the needs of the faculty and students. Satisfaction with the two possible methods of conducting this assessment suggests it would be reasonable to conduct this examination online in the future.

Incidence and Predictors of Ventilator-Associated Pneumonia Among Adult Intubated Patients in Bahir Dar Specialized Hospitals, 2021: A Retrospective Follow-Up Study

INTRODUCTION

Ventilator-associated pneumonia refers to pneumonia that happens at least 48 hours after endotracheal intubation. It is associated with high economic costs, longer attributable lengths of stay in the hospital, and high mortality. Therefore, this study aims to determine the incidence and predictors of ventilator-associated pneumonia among adult intensive care unit admitted patients at Bahir Dar Specialized Hospitals.

METHODS

A retrospective follow-up study was conducted among 312 adult intensive care unit admitted patients. A data extraction checklist was used to collect the data. The collected data were coded, cleaned, and entered into EpiData version 3.1 and exported to SPSS version 22 and STATA version 14 for analysis. Descriptive analysis was done by using tables, text and percentages. Bivariable and multivariable log binomial analyses were conducted to identify predictors of ventilator-associated pneumonia. Variables having p-value <0.05 were considered statistically significant.

RESULTS

The study found that 27.9% (95% CI: 23%-33%) of patients developed ventilator-associated pneumonia and the incidence rate of VAP was 45.7 per 1000 ventilator days. Patient's stay more than or equal to 14 days (ARR: 13, 95% CI: 9.3-31) and 7-13 days on MV (ARR: 7.2, 95% CI: 6.2-11), blood transfusion (ARR: 2.8, 95% CI: 1.1-6.9), low GCS (ARR: 2.5, 95% CI: 1.3-5.1), use of corticosteroid (ARR: 2.1, 95% CI: 1.1-4.1), and supine head position (ARR: 8.1, 95% CI: 1.7-40) were identified as independent predictors of ventilator associated pneumonia.

CONCLUSION

Nearly one-fourth of the participants developed ventilator-associated pneumonia. Duration of ventilation, blood transfusion, corticosteroid use, supine head position, and low Glasgow coma scale were significant predictors of ventilator-associated pneumonia.

Efficacy of Telemedicine Utilization for Cardiac Outpatients’ Care during the Pandemic of COVID-19: A Large Center Experience in the Wave of the Pandemic

Introduction

Synchronous telemedicine using teleconferencing may play a role in clinical care. In a tertiary care center, video conferencing-enhanced virtual clinics were established via a new application platform. They were introduced during COVID-19 pandemic to connect patients to trained health-care providers via a secured line. While maintaining patients' privacy, they were theorized to offer effective communications and continuous clinical care. In this cross-sectional cohort study, we ought to examine the impact of service and the assistance they may offer to cardiac patients in the outpatient setup.

Methods

A prospective cohort study looking at all video-conferencing virtual clinics' visits during the pandemic with primary focus on cardiac outpatient clinic, addressing primary endpoints of need for admission or emergency visits from cardiac demises during the pandemic and secondary endpoint of patient satisfaction based on patients' experiences.

Results

A total of 6000 live care video-based chats were made over 10 months period from March 10^th, 2020, to January 30^th, 2021, among which 277 patients were evaluated in the virtual cardiac clinic, of these 193 (69.7%) were males, with mean age of 48 ± 15.60 (22.3%), patients were requested to present to clinic for further evaluation and testing, 20 (7.2%) patients were asked to visit the emergency room, of whom 8 (2.8%) patients were hospitalized. All 8 were admitted for high-risk findings that require immediate medical attention, 4/8 underwent cardiac catheterization, mean duration of admission was 2 ± 1 days. When compared to regular walk-in care, there was a statistical difference in admission rate and emergency visits p = 0.001 and p = 0.0001, respectively, both were statistically higher in the virtual clinic. The satisfaction rate in a 5-scale grading system was 97% of 4 and above recommending the continuation of the service beyond pandemic time.

Conclusions

Video-enhanced virtual cardiology clinic works safely and efficiently during COVID-19 pandemic with a difference in admission rate and ER visits when compared to walk-in clinic. It can be used during nonpandemic time to reduce load on hospital and clinic crowdedness. It also decreases the chances of COVID-19 transmission indirectly by reenforcing physical distance.

Different applications of telemedicine - assessing the challenges, barriers, and opportunities- a narrative review

Telemedicine (TLM) is a technique of telecommunication used to create, promote, or accelerate health services. Because of its societal significance, the current study attempted to demonstrate its essential applications in the health sector and the challenges, obstacles, and opportunities that lie ahead. Various studies and reports were received based on the subject of the current study, first using MeSH terms related to the subject in authentic and available international databases. After that, 30-related articles were selected based on the study criteria, and then the required results were extracted from the selected studies. The study results showed that TLM has a significant role in more than 13 major areas of health and treatment, and in most of these areas, it has made the relevant affairs easier for both patients and medical staff. Although TLM has many advantages, it still has obstacles and challenges requiring further studies to manage this technology better. Given the high importance of the TLM in the health sector in most countries worldwide, efforts are needed to promote this technology and remove the obstacles in front of it. Therefore, further evaluations of TLM efficiency in terms of economics, speed of action, effectiveness, and the provision of infrastructure are necessary to overcome the obstacles highlighted based on the results of these studies and improve the efficiency of using this technology.

Use of a Smartphone to Gather Parkinson's Disease Neurological Vital Signs during the COVID-19 Pandemic

Introduction

To overcome travel restrictions during the COVID-19 pandemic, consumer-based technology was rapidly deployed to the smartphones of individuals with Parkinson's disease (PD) participating in a 12-month exercise trial. The aim of the project was to determine the feasibility of utilizing a combined synchronous and asynchronous self-administered smartphone application to characterize PD symptoms.

Methods

A synchronous video virtual visit was completed for the administration of virtual Movement Disorder Society-Unified Parkinson's Disease Rating Scale III (vMDS-UPDRS III). Participants asynchronously completed a mobile application consisting of a measure of upper extremity bradykinesia (Finger Tapping Test) and information processing.

Results

Twenty-three individuals completed the assessments. The mean vMDS-UPDRS III was 23.65 ± 8.56 points. On average, the number of taps was significantly greater for the less affected limb, 97.96 ± 17.77 taps, compared to the more affected, 89.33 ± 18.66 taps (p = 0.025) with a significantly greater number of freezing episodes for the more affected limb (p < 0.05). Correlation analyses indicated the number of errors and the number of freezing episodes were significantly related to clinical ratings of vMDS-UPDRS III bradykinesia (Rho = 0.44, p < 0.01; R = 0.43, p < 0.01, resp.) and finger tapping performance (Rho = 0.31, p = 0.03; Rho = 0.32, p = 0.03, resp.). Discussion. The objective characterization of bradykinesia, akinesia, and nonmotor function and their relationship with clinical disease metrics indicate smartphone technology provides a remote method of characterizing important aspects of PD performance. While theoretical and position papers have been published on the potential of telemedicine to aid in the management of PD, this report translates the theory into a viable reality.

Development and Operation of a Video Teleconsultation System Using Integrated Medical Equipment Gateway: a National Project for Workers in Underserved Areas

Worker health centers and health zones provide occupational healthcare services to workers in underserved areas of industrial health. Health zones cannot counsel workers on occupational disease prevention; worker health center personnel have to provide such services through in-person visits. Video teleconsultation can increase the accessibility of high-quality services to workers who visit health zones and improve professional personnel’s efficiency. This study aimed to develop a system and an infrastructure that could facilitate video teleconsultation services between worker health centers and health zones, and analyze the services’ operation status. A video teleconsultation process based on the role of local and remote institutions was designed. Based on the designed services, a web system supporting teleconsultation and an integrated gateway guaranteeing the interface with medical equipment in the web environment was developed. After analyzing the working environment, an infrastructure consisting of networks, video equipment, medical equipment, and servers necessary for teleconsultation was designed. Statistical results from the developed system and a satisfaction survey conducted by the Korea Occupational Safety and Health Agency were used to analyze the video teleconsultation services’ operation status. A system, gateway, and hardware infrastructure within 21 worker health centers and 21 health zones has been operating this service since January 1, 2018. Over two years, the total number of teleconsultation service users was 4979, and the total number of questionnaire respondents was 1270. The total number of service activities was 6388 and total satisfaction was rated as 4.58 (± 0.59) out of 5. In this study, video teleconsultation services were evaluated as being very satisfactory. In particular, service accessibility and local medical personnel service were rated highly, demonstrating that the developed system and infrastructure were well designed according to the goals of the project.

Assessment of Disparities in Digital Access Among Medicare Beneficiaries and Implications for Telemedicine

This cross-sectional study uses data from the 2018 American Community Survey to assess disparities in digital access among Medicare beneficiaries by demographic and socioeconomic characteristics.

Important Administrative Aspects of Critical Care Telemedicine Programs

Conceptualizing, designing, implementing, and sustaining a successful critical care telemedicine program is a complex undertaking. All of these steps must be fully accomplished as a joint effort between a host facility and the telemedicine service provider. Important administrative considerations that must be incorporated into planning and execution steps include managing change. We briefly discuss critical aspects of establishing a sustainable business model, and aligning the critical care telemedicine program with institutional vision, goals, and mission. Discussed are important telemedicine provider infrastructure, key personnel considerations, and how a program defines and measures value.

Telementoring of primary care providers delivering hepatitis C treatment in New York City: Results from Project INSPIRE

INTRODUCTION

The recent availability of highly effective, easily administered, and relatively nontoxic treatments for hepatitis C virus (HCV) infection provides an opportunity for clinicians to treat HCV in nonspecialist settings with appropriate support. Project INSPIRE provides care coordination to HCV patients and a web-based training program (telementoring) on disease management and treatment by HCV specialists to primary care providers inexperienced in HCV treatment. Weekly telementoring sessions use a didactic and case-based approach to instruct non-HCV providers on how to identify and assess HCV treatment candidates and prescribe appropriate treatment.

METHODS

We used mixed methods to assess the telementoring service, including provider surveys and semistructured interviews. Quantitative data were analyzed using descriptive statistics, and qualitative data were analyzed to identify dominant themes.

RESULTS

Provider survey responses indicated an increased ability to identify and evaluate HCV treatment candidates and increased confidence in sharing knowledge with peers and patients. Interviews revealed a high degree of satisfaction with the telementoring service and Project INSPIRE overall. The telementoring service was viewed as having enhanced providers' knowledge, confidence, and ability to treat their own HCV-infected patients rather than having to refer them to an HCV specialist with resulting benefits for continuity of care. Providers reported comradery and collegiality with other INSPIRE providers and satisfaction with professional growth from attaining new knowledge and skills via the telementoring service.

CONCLUSIONS

Using readily available web conferencing technology, telementoring can facilitate knowledge transfer between specialists and primary care providers, facilitating continuity of care for patients and increased provider satisfaction.

Teleconsultation Program for Deployed Soldiers and Healthcare Professionals in Remote and Austere Environments

Background: In April 2004, the US Army Medical Department approved the use of the Army Knowledge Online (AKO) electronic e-mail system as a teleconsultation service for remote teledermatology consultations from healthcare providers in Iraq, Kuwait, and Afghanistan to medical subspecialists in the United States. The success of the system has resulted in expansion of the telemedicine program to include 11 additional clinical specialty services: (1) burn-trauma; (2) cardiology; (3) dermatology; (4) infectious disease; (5) nephrology; (6) ophthalmology; (7) pediatric intensive care; (8) preventive and occupational medicine; (9) neurology; (10) rheumatology; and (11) toxicology. The goal of the program is to provide a mechanism for enhanced diagnosis of remote cases resulting in a better evacuation system (i.e., only evacuation of appropriate cases). The service provides a standard practice for managing acute and emergent care requests between remote medical providers in austere environments and rear-based specialists in a timely and consistent manner.

Methods: Consults are generated using the AKO e-mail system routed through a contact group composed of volunteer, on-call consults. The project manager receives and monitors all teleconsultations to ensure Health Insurance Portability and Accountability Act compliance and consultant's recommendations are transmitted within a 24-hour mandated time period. A subspecialty “clinical champion” is responsible for recruiting consultants to answer teleconsultations and developing a call schedule for each specialty. Subspecialties may have individual consultants on call for specific days (e.g., dermatology and toxicology) or place entire groups on-call for a designated period of time (e.g., ophthalmology).

Results: As of May 2007, 2,337 consults were performed during 36 months, with an average reply time of five hours from receipt of the teleconsultation until a recommendation was sent to the referring physician. Most consultations have been for dermatology (66%), followed by infectious disease (10%). A total of 51 known evacuations were prevented from use of the program, while 63 known evacuations have resulted following receipt of the consultants' recommendation. A total of 313 teleconsultations also have been performed for non-US patients.

Conclusions: The teleconsultation program has proven to be a valuable resource for physicians deployed in austere and remote locations. Furthermore, use of such a system for physicians in austere environments may prevent unnecessary evacuations or result in appropriate evacuations for patients who initially may have been “underdiagnosed.”

Evaluation of new technologies in health-care systems: what’s the context?

Evaluation is an essential component of the introduction of new technologies, treatment modalities and models of service delivery across the health-care sector. Such work attracts significant levels of public funding, but little attention has been paid to understanding evaluation as more than a set of applied methodological activities. This paper sets out an agenda for a more complex and richer understanding of evaluation as a set of professional and organizational dynamics.

Patient satisfaction in telemedicine

Recent improvements in technology and telecommunications have resulted in renewed interest in telemedicine [1]. The UK’s National Health Service (NHS) Executive has recently published an ‘Information for Health’ strategy which states that ‘telemedicine and telecare will undoubtedly come to the fore as a way of providing services in the future. They have a key role to play in the Government’s plans to modernize the NHS’ [2]. Within the current climate, the future success of telemedicine will depend on patient and provider acceptance of such technologies. It is, therefore, imperative that the views and experiences of the users and providers of healthcare services are sought to enable problems to be resolved and issues addressed before telemedicine is fully implemented: ‘Information about the patients’ experiences can be an important lever for change, both highlighting where, and what sort of quality improvements are needed’ [3].

This paper provides an overview of telemedicine and patient satisfaction and considers the satisfaction studies to date. It finally discusses some of the problems in assessing patient satisfaction within telemedicine and how future studies may be improved in light of the findings. It is based upon work that is presently being carried out at the School of Health and Related Research (ScHARR) at the University of Sheffield as part of a Randomized Controlled Trial of telemedicine in dermatology, funded by the NHS Executive Research and Development Programme.

Information Retrieval in Telemedicine: a Comparative Study on Bibliographic Databases

Background and Aims:

The first step in each systematic review is selection of the most valid database that can provide the highest number of relevant references. This study was carried out to determine the most suitable database for information retrieval in telemedicine field.

Methods:

Cinhal, PubMed, Web of Science and Scopus databases were searched for telemedicine matched with Education, cost benefit and patient satisfaction. After analysis of the obtained results, the accuracy coefficient, sensitivity, uniqueness and overlap of databases were calculated.

Results:

The studied databases differed in the number of retrieved articles. PubMed was identified as the most suitable database for retrieving information on the selected topics with the accuracy and sensitivity ratios of 50.7% and 61.4% respectively. The uniqueness percent of retrieved articles ranged from 38% for Pubmed to 3.0% for Cinhal. The highest overlap rate (18.6%) was found between PubMed and Web of Science. Less than 1% of articles have been indexed in all searched databases.

Conclusion:

PubMed is suggested as the most suitable database for starting search in telemedicine and after PubMed, Scopus and Web of Science can retrieve about 90% of the relevant articles.

Patient perspectives of telemedicine quality

BACKGROUND

The purpose of this study was to explore the quality attributes required for effective telemedicine encounters from the perspective of the patient.

METHODS

We used a multi-method (direct observation, focus groups, survey) field study to collect data from patients who had experienced telemedicine encounters. Multi-perspectives (researcher and provider) were used to interpret a rich set of data from both a research and practice perspective.

RESULTS

The result of this field study is a taxonomy of quality attributes for telemedicine service encounters that prioritizes the attributes from the patient perspective. We identify opportunities to control the level of quality for each attribute (ie, who is responsible for control of each attribute and when control can be exerted in relation to the encounter process). This analysis reveals that many quality attributes are in the hands of various stakeholders, and all attributes can be addressed proactively to some degree before the encounter begins.

CONCLUSION

Identification of the quality attributes important to a telemedicine encounter from a patient perspective enables one to better design telemedicine encounters. This preliminary work not only identifies such attributes, but also ascertains who is best able to address quality issues prior to an encounter. For practitioners, explicit representation of the quality attributes of technology-based systems and processes and insight on controlling key attributes are essential to implementation, utilization, management, and common understanding.

Marked reductions in visual impairment due to diabetic retinopathy achieved by efficient screening and timely treatment

PURPOSE

Diabetic retinopathy (DR) is the most common complication of diabetes and needs to be diagnosed early to prevent severe sight-threatening retinopathy. Digital photography with telemedicine connections is a novel way to deliver cost-effective, accessible screening to remote areas. Screening for DR in a mobile eye examination unit (EyeMo) is compared to traditional service models (i.e. local municipal services or a commercial service provider). The quality of images, delays from screening to treatment, the stage of DR, coverage of screening and the rate of visual impairment due to DR are evaluated.

METHODS

EyeMo utilizes telemedicine technology. The electronic databases of the hospital and information from the Finnish Register of Visual Impairment were used to determine delays and the rate of visual impairment.

RESULTS

Fourteen thousand eight hundred and sixty-six fundus photographs were taken in EyeMo in 2007-2011. Coverage reached 78% of potential clients. No DR was detected in 43%, mild background retinopathy in 23%, moderate or severe background retinopathy in 31% and proliferative retinopathy in 3% of the evaluations. The quality of images was higher (p < 0.01) and delays shorter (p < 0.01) in EyeMo as compared to traditional service models. The rate of visual impairment due to DR decreased by 86% in the area covered by EyeMo, and the change compared favourably to the situation in the entire Finland (p < 0.0005).

CONCLUSION

EyeMo is a feasible model of telemedicine application for screening of DR. Effective screening and timely access to care may indeed have influenced the reduced rate of visual damage.

The costs of critical care telemedicine programs: a systematic review and analysis

BACKGROUND

Implementation of telemedicine programs in ICUs (tele-ICUs) may improve patient outcomes, but the costs of these programs are unknown. We performed a systematic literature review to summarize existing data on the costs of tele-ICUs and collected detailed data on the costs of implementing a tele-ICU in a network of Veterans Health Administration (VHA) hospitals.

METHODS

We conducted a systematic review of studies published between January 1, 1990, and July 1, 2011, reporting costs of tele-ICUs. Studies were summarized, and key cost data were abstracted. We then obtained the costs of implementing a tele-ICU in a network of seven VHA hospitals and report these costs in light of the existing literature.

RESULTS

Our systematic review identified eight studies reporting tele-ICU costs. These studies suggested combined implementation and first year of operation costs for a tele-ICU of $50,000 to $100,000 per monitored ICU-bed. Changes in patient care costs after tele-ICU implementation ranged from a $3,000 reduction to a $5,600 increase in hospital cost per patient. VHA data suggested a cost for implementation and first year of operation of $70,000 to $87,000 per ICU-bed, depending on the depreciation methods applied.

CONCLUSIONS

The cost of tele-ICU implementation is substantial, and the impact of these programs on hospital costs or profits is unclear. Until additional data become available, clinicians and administrators should carefully weigh the clinical and economic aspects of tele-ICUs when considering investing in this technology.

Centralization of a regional clinical microbiology service: The Calgary experience

Diagnostic laboratory services in Alberta have been dramatically restructured over the past five years. In 1994, Alberta Health embarked on an aggressive laboratory restructuring that cut back approximately 30% of the overall monies previously paid to the laboratory service sector in Calgary. A unique service delivery model consolidated all institutional and community-based diagnostic testing in a company called Calgary Laboratory Services (CLS) in late 1996. CLS was formed by a public/private partnership between the Calgary Regional Health Care Authority (CRHA) and MDS-Kasper Laboratories. By virtue of its customer service base and scope of testing, CLS provides comprehensive regional laboratory services to the entire populace. Regional microbiology services within CLS have been successfully consolidated over the past three years into a centralized high volume laboratory (HVL). Because the HVL is not located in a hospital, rapid response laboratories (RRLs) are operated at each acute care site. Although the initial principle behind the proposed test menus for the RRLs was that only procedures requiring a clinical turnaround time of more than 2 h stay on-site, many other principles had to be used to develop and implement an efficient and clinically relevant RRL model for microbiology. From these guiding principles, a detailed assessment of the needs of each institution and extensive networking with user groups, the functions of the microbiology RRLs were established and a detailed implementation plan drawn up. The experience at CLS with regards to restructuring a regional microbiology service is described herein. A post-hoc analysis provides the pros and cons of directing and operating a regionalized microbiology service.

Use of telemedicine and other strategies to increase the number of patients that may be treated with intravenous thrombolysis

Stroke is the fourth leading killer in the United States and a leading cause of adult long-term disability. The American Heart Association estimates that only 3% to 5% of patients with acute ischemic stroke are treated with intravenous thrombolysis. A way to improve the rates of treatment with thrombolysis in patients with acute ischemic stroke is the creation of telemedicine stroke networks. Data from many studies support the safety of expanding intravenous tissue plasminogen activator use with the help of telemedicine. In this article we discuss the current evidence for the use of telemedicine within stroke systems of care, the importance of coordinating care within the transferring facilities in the telestroke networks, telestroke economics and applicability, and how to potentially use the telestroke systems to increase recruitment of patients into acute stroke thrombolysis trials.

Detection of clinically significant retinopathy of prematurity using wide-angle digital retinal photography: a report by the American Academy of Ophthalmology

OBJECTIVE

To evaluate the accuracy of detecting clinically significant retinopathy of prematurity (ROP) using wide-angle digital retinal photography.

METHODS

Literature searches of PubMed and the Cochrane Library databases were conducted last on December 7, 2010, and yielded 414 unique citations. The authors assessed these 414 citations and marked 82 that potentially met the inclusion criteria. These 82 studies were reviewed in full text; 28 studies met inclusion criteria. The authors extracted from these studies information about study design, interventions, outcomes, and study quality. After data abstraction, 18 were excluded for study deficiencies or because they were superseded by a more recent publication. The methodologist reviewed the remaining 10 studies and assigned ratings of evidence quality; 7 studies were rated level I evidence and 3 studies were rated level III evidence.

RESULTS

There is level I evidence from ≥5 studies demonstrating that digital retinal photography has high accuracy for detection of clinically significant ROP. Level III studies have reported high accuracy, without any detectable complications, from real-world operational programs intended to detect clinically significant ROP through remote site interpretation of wide-angle retinal photographs.

CONCLUSIONS

Wide-angle digital retinal photography has the potential to complement standard ROP care. It may provide advantages through objective documentation of clinical examination findings, improved recognition of disease progression by comparing previous photographs, and the creation of image libraries for education and research.

[Economic aspects of integrated care]

For more than 10 years integrated care has been an inherent part of the German healthcare system. The aims of selective contracts are to minimize interface problems between outpatient and inpatient sectors, generalist und specialist care as well as to intensify competition. Despite repeated efforts by the legislator, comprehensive integrated healthcare is still limited to a few flagship projects. This is mainly due to low incentives on the part of both suppliers and customers. Therefore, this article focuses on the economic aspects of integrated care. From a theoretical perspective, integrated care improves efficiency in the healthcare sector by reducing interface problems and asymmetric information as well as by intensifying competition. In practice, however, there are a number of obstacles to implementation. Particularly noteworthy are the financial difficulties in addition to problems regarding sectoral budgeting and the long-term nature of investments. However, the political environment and thus the financial arrangements within the statutory health insurance seem to be more important for further development of integrated care in Germany than the financing issues.

Differences in readiness between rural hospitals and primary care providers for telemedicine adoption and implementation: findings from a statewide telemedicine survey

PURPOSE

Published advantages of and challenges with telemedicine led us to examine the scope of telemedicine adoption, implementation readiness, and barriers in a southern state where adoption has been historically low. We hypothesized that rural hospitals and primary care providers (RPCPs) differ on adoption, readiness, and implementation barriers. We examined the degree to which they differ on (a) telemedicine adoption or readiness; (b) telemedicine training needs; (c) current use of technology for patient care; and (d) environmental concerns in facilities for telemedicine.

METHODS

Paper surveys were sent to rural hospitals and RPCPs with response rates of 50% (n = 38) and 25.9% (n = 339), respectively. Three of 4 hospitals were represented. Chi-square analyses were used to test for differences between rural hospitals and RPCPs.

FINDINGS

Compared to RPCPs, rural hospitals were significantly more likely to report higher rates of telemedicine knowledge (P= .0007); planning for or implementing telemedicine (P < .0001); and reporting their disaster recovery data systems (P= .0002) and availability and location of outlets and connections (P= .03) as adequate for telemedicine. Rural hospitals were less likely to report having no telemedicine education needs (P= .04).

CONCLUSIONS

Telemedicine continues to be a viable solution for bridging geographic access gaps to a variety of specialty care. Users need assistance in understanding legal implications, care coordination, billing for services, and disaster data recovery. In rural areas, hospitals appear to best embody characteristics of facilities that successfully implement telemedicine and have the greatest degree of readiness.

Telemedicine: What have we learned?

As the health care industry is facing many challenges and is undergoing extensive change, telemedicine is in the position to address these challenges and be an important part of health care's development. Telemedicine has been used for approximately a half century, in which researchers have explored the different technologies utilized, clinical outcomes, cost benefits, perceptions, and adoption challenges of its use. This paper reviews and summarizes these findings and presents possible future research endeavors. Examining what is known about telemedicine can aid in the development of innovative, sustainable and beneficial health technologies that could positively impact health care delivery and outcomes.

Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP): 24-month experience with telemedicine screening

PURPOSE

To report the 24-month experience of the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) telemedicine initiative.

METHODS

Retrospective analysis of the SUNDROP archival data gathered between 1 December 2005 and 30 November 2007 to evaluate this diagnostic technology for ROP screening. One hundred and sixty consecutively enrolled infants meeting ROP examination criteria were screened with the RetCam II and evaluated by the SUNDROP reading centre at Stanford University. Nurses obtained five or six images in each eye. All patients also received a dilated examination within 1 week of discharge. Outcomes included treatment-warranted retinopathy of prematurity (TW-ROP) and anatomical outcomes.

RESULTS

In the initial 24-month period, the SUNDROP telemedicine initiative has not missed any TW-ROP. A total of 160 infants (320 eyes) were imaged, resulting in 669 exams and 7556 images. Seven infants were identified with TW-ROP; six underwent laser photocoagulation and one regressed spontaneously. The sensitivity was 100%, with specificity of 99.4%. No patient progressed to retinal detachment or other adverse outcomes.

CONCLUSION

The SUNDROP telemedicine screening initiative for ROP has been proven to have a high degree of sensitivity and specificity for the identification of treatment-warranted disease. All cases of treatment-warranted disease were captured. There were no adverse outcomes.

Telehealth ethics

The ethical implications of telehealth go well beyond providers' obligations to ensure privacy and confidentiality. The ethical conundrum of telehealth realizes the uniquely positive impact that telehealth can have on patients, providers, and clinical outcomes, as well as the potential for harm and abuse that may ensue. This article explores telehealth as one of many evolving information technologies that have ethical questions extending well beyond the confines of privacy and confidentiality. Providers and systems who utilize telehealth should also consider how it influences relationships with patients, access to healthcare, capacity for equitable treatment, cost, and quality of life. The ability to respond to these concerns will be important to the future development and deployment of this important technology as one means by which to improve access and quality of healthcare for all members of our society.

Image analysis for retinopathy of prematurity diagnosis

PURPOSE

To review findings from the authors' published studies involving telemedicine and image analysis for retinopathy of prematurity (ROP) diagnosis.

METHODS

Twenty-two ROP experts interpreted a set of 34 wide-angle retinal images for presence of plus disease. For each image, a reference standard diagnosis was defined from expert consensus. A computer-based system was used to measure individual and linear combinations of image parameters for arteries and veins: integrated curvature (IC), diameter, and tortuosity index (TI). Sensitivity, specificity, and receiver operating characteristic areas under the curve (AUC) for plus disease diagnosis were determined for each expert. Sensitivity and specificity curves were calculated for the computer-based system by varying the diagnostic cutoffs for arterial IC and venous diameter. Individual vessels from the original 34 images were identified with particular diagnostic cutoffs, and combined into composite wide-angle images using graphics editing software.

RESULTS

For plus disease diagnosis, expert sensitivity ranged from 0.308-1.000, specificity from 0.571-1.000, and AUC from 0.784 to 1.000. Among computer system parameters, one linear combination had AUC 0.967, which was greater than that of 18 of 22 (81.8%) experts. Composite computer-generated images were produced using the arterial IC and venous diameter values associated with 75% under-diagnosis of plus disease (ie, 25% sensitivity cutoff), 50% under-diagnosis of plus disease (ie, 50% sensitivity cutoff), and 25% under-diagnosis of plus disease (ie, 75% sensitivity cutoff).

CONCLUSIONS

Computer-based image analysis has the potential to diagnose severe ROP with comparable or better accuracy than experts, and could provide added value to telemedicine systems. Future quantitative definitions of plus disease might improve diagnostic objectivity.

Telemedicine for retinopathy of prematurity diagnosis: evaluation and challenges

Retinopathy of prematurity (ROP) is a vasoproliferative disorder affecting low birth weight infants. Although timely diagnosis and treatment can significantly reduce the risk of severe complications, ROP remains a leading cause of childhood blindness worldwide. Limitations of current disease management strategies include extensive travel and logistical coordination requirements for ophthalmologists and neonatologists, decreasing availability of adequately trained ophthalmologists at the point of care, variability in how retinal findings are diagnosed and documented, and a growing need for ROP care worldwide. Store-and-forward telemedicine is an emerging technology by which medical data are captured for subsequent interpretation by a remote expert. This has potential to improve accessibility, quality, and cost of ROP management. In this article, we summarize the current evaluation data on applications of telemedicine for ROP, particularly involving the diagnostic accuracy and reliability of remote image interpretation by experts. We also address challenges such as the cost-effectiveness of telemedicine, and highlight potential barriers to implementation of these systems. Understanding these principles is essential to determine future directions in research and development of telemedicine systems for ROP, as well as for other ophthalmic diseases.

Remote Hearing Screenings via Telehealth in a Rural Elementary School

Purpose

Telehealth (telepractice) is the provision of health care services using telecommunications. Telehealth technology typically has been employed to increase the level of health care access for consumers living in rural communities. In this way, audiologists can use telehealth to provide services in the rural school systems. This is important because school hearing screening programs are the foundation of educational audiology programs. Therefore, the goal of this study was to determine the feasibility of providing hearing screening services by telehealth technology to school-age children.

Method

Hearing screening services—including otoscopy, pure-tone, and immittance audiometry—were conducted on 32 children in 3rd grade attending an elementary school in rural Utah. Each child received 1 screening on-site and another through telehealth procedures.

Results

Immittance and otoscopy results were identical for on-site and telehealth screening protocols. Five children responded differently to pure-tone stimuli presented by the telehealth protocol than by the on-site protocol. However, no statistically significant difference was found for pure-tone screening results obtained by telehealth or on-site screening procedures (binomial test, p = .37). Likewise, overall screening results obtained by traditional and telehealth procedures were not statistically significant (binomial test, p = .37).

Conclusion

The results of this study suggest that school hearing screenings may be provided using telehealth technology. This study did find that 5 students performed differently to pure-tone screenings administered by the telehealth protocol in contrast to on-site hearing screening services. Further research is necessary to identify factors leading to false responses to pure-tone hearing screening when telehealth technology is used. In addition, telehealth hearing screening protocols should be conducted with participants of different age groups and experiencing a wide range of hearing loss to further clarify the value of telehealth technology.

Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP): 18-month experience with telemedicine screening

PURPOSE

To report the 18-month experience of the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) telemedicine initiative.

DESIGN

Retrospective analysis of the SUNDROP archival data between 1 December 2005 and 30 May 2007, evaluating this new diagnostic technology for ROP screening.

PARTICIPANTS

All 97 consecutively enrolled infants in the SUNDROP network.

METHODS

All patients were screened using the RetCam II, and evaluated by the SUNDROP reading center at Stanford University. Nurses were trained to obtain five images in each eye. All patients were screened by an ophthalmologist trained in diagnosing ROP within 1 week of discharge from the hospital.

MAIN OUTCOME MEASURES

Outcomes included referral-warranted disease, need for treatment, and anatomic outcomes. Referral-warranted disease was defined as any Early Treatment Retinopathy of Prematurity Disease Type 2 or greater, threshold disease, any plus disease, and any stage 4 or higher disease.

RESULTS

In the initial 18-month period, the SUNDROP telemedicine screening initiative has not missed any referral-warranted disease for ROP. A total of 97 infants (194 eyes) were enrolled, resulting in 443 unique examinations and 4,929 unique images. The mean birth weight of the infants was 1,186.9 grams, with a mean gestational age at birth of 28.9 weeks. Seven infants were identified with referral-warranted disease; six patients underwent laser photocoagulation and completely regressed. The one remaining patient regressed spontaneously, and did not require intervention. Calculated sensitivity and specificity was 100% and 98.9% respectively. No patient progressed to retinal detachment or other adverse outcome. Inadequate exposure, artifact, poor visualization of the periphery, and lack of a complete standardized image set in some patients were identified as areas requiring further assessment.

CONCLUSIONS

The SUNDROP telemedicine screening initiative for ROP has proven to have a high degree of sensitivity and specificity for identification of referral-warranted disease. Training was easily implemented. All cases of referral-warranted disease were captured. There were no adverse outcomes.

Telepsychiatry reduces geographic physician disparity in rural settings, but is it financially feasible because of reimbursement?

Telemedicine has been shown to improve rural patient outcomes in two randomized controlled trials, to increase access to many patients, to serve underserved minorities, and to train primary care providers. Yet, programs are dwindling even after successful grants due to inadequate reimbursement. Studies have been thoroughly done to gauge the payor status of potential rural telemedicine patients, as the "floodgates" are not generally open to all-including those who cannot pay-in typical grants. Or the population of one community may not be representative of others. This study is part of a grant that explored the use of telemedicine for rural service delivery, attempted to get a clear snapshot of whom would be served if all were invited (paying or not), and to understand issues with the reimbursement systems. This article (1) examines the receipts of reimbursement and insurance coverage during the 1-year grant period by determining actual versus projected reimbursements, (2) identifies what payor(s) typical patients use, and (3) identifies problems and barriers for future study. Other administrative issues pertinent to telemedicine and costs are briefly discussed (eg, no-show rates, staffing, scheduling).

Telemedicine Taxonomy: A Classification Tool

Telemedicine allows medical doctors and specialized skilled experts to provide services to patients who are in remote locations using advanced telecommunications. This paper presents a taxonomy that systematically classifies various telemedicine efforts worldwide using five major dimensions: application purpose, application area, environmental setting, communication infrastructure, and delivery options. To identify relationships and patterns between these different dimensions telemedicine programs survey data from the Telemedicine Information Exchange (TIE) was analyzed using multiple regression and path analysis. Major findings indicate that interactive video is the most preferred modality. Store-and-forward technology is preferred for ophthalmology, radiology, and pathology. However, a negative correlation exists between store-and-forward and interactive video with mental health application. The study also indicates that the Internet is still not the dominant communications infrastructure when it comes to telemedicine. We showed that these dimensions can capture almost all efforts in telemedicine and also help program planners to understand the issues in telemedicine deployment. Our findings indicate that the taxonomy is useful for categorizing and comparing existing programs, and can be used for planning future programs.

Information and communications technology in chronic disease care: what are the implications for payment?

New information and communication technology (ICT) has the potential to improve care for chronic conditions, deliver better health outcomes, and reduce direct and indirect costs. However, realizing these gains necessitates new forms of care delivery, through adoption of ICT, the specific choice of ICT, and changes to existing forms of health care delivery. Realizing these new forms of delivery requires appropriate payment policies. The authors review the literatures on health care payment and ICT in chronic care and then apply theoretical economic analysis to determine how ICT alters health care payment policy recommendations. Using diabetes as an example, the authors identify and illustrate the disease and technology features that determine the optimal form of payment. Overall, ICT shifts the optimal blend of fee-for-service and capitation toward greater capitation. Carve-outs for ICT-supported preventive care enable more high-powered payment while addressing selection concerns.

Health delivery system changes required when integrating telemedicine into existing treatment flows of information and patients

Business model and financial recovery issues dominate discussions about using telemedicine to improve chronic disease management. The technical issues are numerous, daunting and complex, but many can be addressed using the resources and infrastructure available in large, well-integrated clinical information systems. The cost-benefit balance will change when it becomes possible to use devices that are owned by patients for everyday use, rather than installing special-purpose devices for telemedicine. Technology and communications capabilities are driven mainly by market factors other than uses for health care. Provider-side telemedicine capabilities, specifically for upload, storage and display of home medical data, will improve as technology develops. How health-care providers will process the larger amount of data made available by telemedicine is a clinical issue, but it is likely that software will emerge to assist in this task. The alignment of financial incentives for health-care providers is a decisive factor in understanding why telemedicine has had substantial deployment within the US Veterans Hospital Administration system, and to some extent within prison health systems and the Kaiser Permanente Health Plan, but much less widely in other settings.

Remote image based retinopathy of prematurity diagnosis: a receiver operating characteristic analysis of accuracy

BACKGROUND/AIMS

Telemedicine offers potential to improve the accessibility and quality of diagnosis of retinopathy of prematurity (ROP). The aim of this study was to measure accuracy of remote image based ROP diagnosis by three readers using receiver operating characteristic (ROC) analysis.

METHODS

64 hospitalised infants who met ROP examination criteria underwent two consecutive bedside procedures: dilated examination by an experienced paediatric ophthalmologist and digital retinal imaging with a commercially available wide angle camera. 410 images from 163 eyes were reviewed independently by three trained ophthalmologist readers, who classified each eye into one of four categories: no ROP, mild ROP, type 2 prethreshold ROP, or ROP requiring treatment. Sensitivity and specificity for detection of mild or worse ROP, type 2 prethreshold or worse ROP, and ROP requiring treatment were determined, compared to a reference standard of dilated ophthalmoscopy. ROC curves were generated by calculating values for each reader at three diagnostic cut-off levels: mild or worse ROP (that is, reader was asked whether image sets represented mild or worse ROP), type 2 prethreshold or worse ROP (that is, reader was asked whether image sets represented type 2 prethreshold or worse ROP), and ROP requiring treatment.

RESULTS

Areas under ROC curves ranged from 0.747-0.896 for detection of mild or worse ROP, 0.905-0.946 for detection of type 2 prethreshold or worse ROP, and 0.941-0.968 for detection of ROP requiring treatment.

CONCLUSIONS

Remote interpretation is highly accurate among multiple readers for the detection of ROP requiring treatment, but less so for detection of mild or worse ROP.

Teledentistry for screening new patient orthodontic referrals. Part 2: GDP perception of the referral system

OBJECTIVE

To evaluate GDP opinion about a teledentistry system to screen new patient orthodontic referrals.

STUDY DESIGN

Cross-sectional questionnaire.

SAMPLE

Two hundred general dental practitioners (GDPs) were approached from Stockport, Rochdale, Oldham, Bury and Bolton in Greater Manchester, and High Peak in Derbyshire.

METHOD

A questionnaire about a teledentistry system for new orthodontic patients was developed, following interviews with eight GDPs participating in a teledentistry trial. The questionnaire was posted to another 200 GDPs who were asked questions on issues such as the efficiency of a teledentistry system; the usefulness of a teledentistry system from the patients' point of view; their view of a teledentistry system; and any concerns they had relating to security, confidentiality and consent.

RESULTS

Seventy one per cent of GDPs thought teledentistry for orthodontic referrals would be a good idea. At least 90% of responders agreed or neither agreed nor disagreed that patients would benefit from such a system. Over half of GDPs agreed or strongly agreed that there would be implications on their surgery time, expense and equipment security.

CONCLUSIONS

GDPs generally supported a teledentistry system for new patient orthodontic referrals. Although perceived patient advantages were agreed, GDPs tended to be less sure about the impact on them in terms of set-up expenses, time in the surgery and appropriate remuneration.

A randomized trial comparing telemedicine case management with usual care in older, ethnically diverse, medically underserved patients with diabetes mellitus

BACKGROUND

Telemedicine is a promising but largely unproven technology for providing case management services to patients with chronic conditions who experience barriers to access to care or a high burden of illness.

METHODS

The authors conducted a randomized, controlled trial comparing telemedicine case management to usual care, with blinding of those obtaining outcome data, in 1,665 Medicare recipients with diabetes, aged 55 years or greater, and living in federally designated medically underserved areas of New York State. The primary endpoints were HgbA1c, blood pressure, and low-density lipoprotein (LDL) cholesterol levels.

RESULTS

In the intervention group (n = 844), mean HgbA1c improved over one year from 7.35% to 6.97% and from 8.35% to 7.42% in the subgroup with baseline HgbA1c > or =7% (n = 353). In the usual care group (n = 821) mean HgbA1c improved over one year from 7.42% to 7.17%. Adjusted net reductions (one-year minus baseline mean values in each group, compared between groups) favoring the intervention were as follows: HgbA1c, 0.18% (p = 0.006), systolic and diastolic blood pressure, 3.4 (p = 0.001) and 1.9 mm Hg (p < 0.001), and LDL cholesterol, 9.5 mg/dL (p < 0.001). In the subgroup with baseline HgbA1c > or =7%, net adjusted reduction in HgbA1c favoring the intervention group was 0.32% (p = 0.002). Mean LDL cholesterol level in the intervention group at one year was 95.7 mg/dL. The intervention effects were similar in magnitude in the subgroups living in New York City and upstate New York.

CONCLUSION

Telemedicine case management improved glycemic control, blood pressure levels, and total and LDL cholesterol levels at one year of follow-up.

Help seeking behavior and the Internet: a national survey

Health-related websites have the potential to powerfully influence the attitudes and behavior of consumers. Access to reliable disease information online has been linked to reduced anxiety, increased feelings of self-efficacy, and decreases in utilization of ambulatory care. Studies report that Internet health information seekers are more likely to have health concerns; adult seekers are more likely to rate themselves as having poor health status and adolescent seekers are more likely to demonstrate clinical impairment or depressive symptomatology compared to non-seekers. Although more and more Americans are using the Internet for healthcare information, little is known about how this information affects their health behaviors. The current study extends the literature by examining characteristics associated with help seeking, either from a healthcare provider or from peers, as a direct result of health information found online. Medical care seekers appear to be using the Internet to enhance their medical care; they report using the information online to diagnose a problem and feel more comfortable about their health provider's advice given the information found on the Internet. Support seekers tend to be of slightly lower income compared to non-support seekers. They are also significantly more likely to have searched for information about a loved one's medical or health condition, signaling that many of these consumers may be caretakers.

Managing suicides via videoconferencing in a remote northern community in Canada

INTRODUCTION

Telehealth in remote communities has been reported to be cost-effective for emergency medicine and possibly for psychiatry.

METHODS

The cost of sending a patient out of a remote community for suicide assessment was compared with the cost of maintenance and on-line charges of videoconference. The cost comparison was used to determine the potential savings to the provincial government. User satisfaction was assessed through qualitative questionnaires.

RESULTS

The use of videoconferencing for mental health assessment for 71 patients in a remote northern community saved the Government of Newfoundland and Labrador dollar 140,088 in 2003. Patients and health professionals were satisfied with mental health assessment via videoconference.

CONCLUSION

The provision of mental health assessments for patients in a remote community in Labrador, Canada by videoconference was effective and saved money.

Privacy and security issues in teleradiology

Teleradiology is now well established within healthcare in the USA, but ethico-legal concepts surrounding this innovation remain unclear. New legislation, the Health Insurance Portability and Accountability Act, as well as ethical guidelines and common law demonstrate the importance being placed on security of electronic data and the protection of patients' personal data. Radiologists need to be aware of the security, privacy, and confidentiality issues which relate to teleradiology, so that they can safeguard not only their own interests but also the best interests of their patients.

A case study: telemedicine technology and peritoneal dialysis in children

We investigated the feasibility and effectiveness of a telemedicine system for monitoring pediatric patients undergoing automated peritoneal dialysis (APD) at home. The system uses modem-based communication between the patient's cycler and a computer in the dialysis unit, which allows data transmission and storage, and live patient-physician interaction by ISDN lines, modem, microphone with stereo speakers, and digital cameras for private video-conferencing and image capture. Two children aged 10 and 12 years, who live 1500 and 40 km from the dialysis unit, respectively, have been using the system for 7 months. All of the APD treatment data were stored and examined; 122 televisits were performed. The APD data show that both patients have complied with their dialysis prescription. The telemedicine system broadens patient/physician interchange and increases the quality of care and the life of children on peritoneal dialysis.

Telemedicine, rural elderly, and policy issues

Historically, rural America has had a difficult time providing health care to its residents, particularly its frail elderly population. Rural health care is often faced with a shortage of health care specialists, facilities with inferior equipment, and insufficient resources compared to health care in more urban areas. It is anticipated that the use of telemedicine will help address many of the problems facing the delivery of health care services to rural elderly. This paper reviews some innovative projects delivering services to the elderly. Also, the paper discusses several issues that need to be addressed before telemedicine can reach its full potential in improving access to health care, including reimbursement policies, patient and provider liability and confidentiality, and the infrastructure supporting telemedicine. Although telecommunications has tremendous potential to address the care needs of frail isolated elderly, without comprehensive reimbursement policies, guidelines for ethical conduct of a teleconsultation, acceptable security measures of patient records, and adequate as well as compatible infrastructure, that potential cannot be completely realized.

The computerized patient record: balancing effort and benefit

PROMISE AND REALITY: this review addresses two questions. First, why is the introduction of the computerized patient record (CPR) so slow, while its potential for improved quality of care and reduction of cost is well recognized? Second, what, in this respect, is the role of record architecture and standardization? BARRIERS: the impediments for CPR adoption are put in a larger context by addressing the relationship among effort, benefit, and the parties involved. An important financial impediment is insufficient return of investment. Other hurdles related to the use of CPRs are lack of integration and flexibility, which cause clinicians to experience insufficient reward to motivate them for data entry and changes in working style. Effort and benefit have to be balanced for each party involved. REQUIREMENTS FOR IMPROVEMENT: lack of standardization impedes exchange and sharing of medical data, and new developments cause fear of applications to become outdated. Flexibility in content and use, integration, and adaptability to change, are key requirements for CPR systems. These requirements can most effectively be met through an architecture that separates content and structure, such that the road to standardization is not paved with frequent expensive adaptations. STRATEGIES FOR IMPLEMENTATION: successful implementation and acceptance require reliable evaluation of applications by independent professional groups. Users need to be involved in setting priorities and planning for actual implementation.
