Clinical and Demographic Differences Among Cancer Survivors With Ostomies With and Without Informal Caregivers.

Informal caregivers have an essential role for cancer survivors (CS). There may be important clinical and demographic differences between CS with ostomies based on caregiver status. Our aim was to identify items that may lead to future recommendations and interventions for CS with ostomies. This is a secondary analysis of 216 CS with ostomies that were enrolled in a clinical trial. Baseline data collected included demographics, clinical characteristics, and surveys (patient activation, self-efficacy, City of Hope Quality of Life - Ostomy). These factors were compared based on caregiver status using chi-squared analysis and t-tests. Logistic regression was used to examine the factors that affect the likelihood of having a caregiver. Most participants had an identified caregiver (57%; 124/216). There was no difference in age based on caregiver status (mean 64.4 and 62.0 for those with and without a caregiver, respectively). Of those with a caregiver, 66.9% were males, 79.0% were partnered, and 87.1% were white. Those with caregivers had a higher prevalence of diabetes (p < 0.001), heart disease (p = 0.002), and mobility issues (p = 0.002). Survivors with caregivers had both higher incomes (p = 0.012) and levels of education (p = 0.049). The only difference in survey measures was those with a caregiver were more successful at getting help when needed (p = .045). Differences in gender and comorbidities of CS with caregivers demand further investigation. Interventions such as encouraging CS without caregivers to utilize available sources of social support, including other survivors with ostomies, may improve their care and quality of life.

Adapting to the burdens of care: a telehealth program for cancer survivors with ostomies.

PURPOSE: An ostomy introduces to cancer survivors new demands for self-care and healthcare resource use. A curriculum that teaches ostomates self-management skills may affect survivors' use of resources. METHODS: A prospective randomized trial comparing usual care (UC) with an Ostomy Self-Management Training (OSMT) program delivered by telehealth was conducted in patients with ostomies due to cancer. The intervention occurred over 5 weeks with survey administration at baseline, program completion, and 6 months after completion. Quantitative data were analyzed using a mixed-effects logistic model to predict mean values of resource and service use. Responses to the open-ended question were coded and analyzed with directed content analysis. RESULTS: One hundred and sixty-seven subjects (89 in the OSMT arm and 78 in the UC arm) completed the questionnaire at all time points. The changes in likelihoods of emptying one's ostomy bag > 8 times/week and of incurring any out-of-pocket costs on accessories were 14% greater for the intervention group (p = .029 and p = .063, respectively). Qualitative analysis reveals among the OSMT arm an increase in the proportion of ostomy-specific comments and a decrease in the same metric among the UC arm. Common themes included learning to work with equipment, dealing with gas build-up and finding well-fitting clothing. CONCLUSIONS: There are some indications that participants in this structured telehealth program are more active in ostomy self-care. The reported ostomy self-care activities, healthcare consumables, and healthcare services reported by both groups illustrate the complexity of survivorship care following ostomy surgery. National Clinical Trial Identifier: NCT02974634.

Stakeholder engagement and participation in the design, delivery, and dissemination of the ostomy self-management telehealth (OSMT) program.

PURPOSE: Stakeholder engagement is increasingly integrated into clinical research processes. We conducted a mixed methods analysis to describe stakeholders' (peer ostomates, ostomy nurses, telehealth engineers) perceptions of their engagement and participation in a multisite, randomized trial of a telehealth-delivered curriculum for cancer survivors with ostomies. METHODS: Stakeholder notes were analyzed using narrative analysis. We constructed a 15-item survey that assessed the following areas: adherence to stakeholder engagement principles, engagement/influence throughout the study process, impact on perceived well-being, and satisfaction. Stakeholders were invited to complete the survey anonymously. Quantitative survey data were tabulated through summary statistics. RESULTS: Across intervention sessions, an average of 7.7 ± 1.4 stakeholders attended and 2.6 ± 1.4 submitted a note per session. The survey response rate was 73% (11/15). Stakeholders reported high agreement that the study adhered to engagement principles (91% reciprocal relationships, 100% co-learning, partnership, and transparency/honesty/trust). They felt highly engaged (18% moderate, 73% great deal) and that they had influence on study initiation (27% moderate, 55% great deal), intervention delivery (9% moderate, 82% great deal), fidelity assessment (18% moderate, 73% great deal), analysis and interpretation (55% moderate, 27% great deal), and dissemination (45% moderate, 45% great deal). They reported high overall satisfaction with roles (91% great deal), believed the program was helpful for participants (91%), and that serving on study team benefited their own well-being (100%). CONCLUSIONS: Our strategy of stakeholder inclusion led to high engagement, input, satisfaction, and belief in success of program, which could be mirrored in other trials.

Cancer survivors' greatest challenges of living with an ostomy: findings from the Ostomy Self-Management Telehealth (OSMT) randomized trial.

OBJECTIVES: An ostomy results in lifelong quality of life changes for a cancer survivor. We describe the greatest challenges reported from a randomized trial of cancer survivors with stomas (ostomies). METHODS: Cancer survivors with ostomies participating in a multi-site randomized prospective trial of an Ostomy Self-Management Telehealth (OSMT) program versus usual care (UC) were surveyed at six months post accrual. An open-ended question requested greatest challenges after ostomy surgery. Quantitative descriptive and qualitative analyses were used to examine greatest challenges reported. RESULTS: A total of 118 trial participants identified greatest challenges with 55 in the OSMT and 63 in the UC. Six conceptual domains were used to code comments-physical, psychological, social, and spiritual quality of life; ostomy-specific issues, and healthcare issues. The OSMT contributed 187 comments, and UC contributed 235 comments. Ostomy specific issues and social well-being had the most comments overall with UC contributing more comments in all domains except physical well-being. Word Clouds revealed post-operative and treatment-related issues and going out in public as the most common challenges in both groups. Word Clouds compared types of ostomies revealing bowel function challenges (colostomy group), difficulties going out in public (ileostomy group), and positive support (urostomy group). CONCLUSIONS: Fewer challenges submitted by the OSMT group provide the beginning evidence of the OSMT program impact. Dominant challenges across both groups were social well-being and ostomy care. Challenges varied by type of ostomy. Findings support long-term care and support for all cancer survivors with ostomies. TRIAL REGISTRATION: NCT02974634.

Analysis of Telehealth Versus Telemedicine Terminology in the Telemedicine and e-Health Journal Between 2010 and 2020.

Introduction: The terms "telemedicine" and "telehealth" are similar, yet, carry different meanings and are often defined differently. Methods: A decadal longitudinal study analyzing the usage of these terms in the Telemedicine and e-Health Journal (TMJ) between 2010 and 2020 was conducted. Looking at the keywords assigned to the "Original Research" articles, "telemedicine" (34%) is used almost three times more than telehealth (12%). Although "other" keywords are assigned at a similar frequency as "telemedicine," a similar pattern is followed for the terms within the text. Results: "Telemedicine" and "other" terms are used the most (36%), while articles using both ("telemedicine" and "telehealth") (15%) or "telehealth" (14%) as terms throughout the article are less. This longitudinal study also analyzed the TMJs editorial board between 2010 and 2020. Most of the board is made up of physicians (MD or DO) (42) or PhDs (33), with 25 out the 75 having dual credentialing. Conclusions: Also, while there is international influence within the board (UK, India, France, Canada, etc.), most of the board is associated with an American organization (educational and/or corporate). Most of the board (34/75) has also been present between 10 and 11 years within the study period (a total of 11 years).

Programmatic Costs of the Telehealth Ostomy Self-Management Training: An Application of Time-Driven Activity-Based Costing.

OBJECTIVES: Programmatic cost assessment of novel clinical interventions can inform their widespread dissemination and implementation. This study aimed to determine the programmatic costs of a telehealth Ostomy Self-Management Training (OSMT) intervention for cancer survivors using Time-Driven Activity-Based Costing (TDABC) methodology. METHODS: We demonstrated a step-by-step application of TDABC based on a process map with core OSMT intervention activities and associated procedures and determined resource use and costs, per unit procedure. We also assessed per-patient costs from a payer perspective and provided estimates of total hours and costs by personnel, activity, and procedure. RESULTS: The per-patient cost of the OSMT was $1758. Personnel time accounted for 91% of the total cost. Site supervisor and information technology technician time were the most expensive personnel resources. Telehealth technical and communication equipment accounted for 8% of the total cost. Intervention coordination and monitoring efforts represented most of the total time cost (62%), followed by the intervention delivery (35%). The procedures with the highest cost were communication via phone or virtual meetings (24%), email exchanges (18%), and telehealth session delivery (18%). CONCLUSIONS: Future efforts to replicate, disseminate, and implement the OSMT intervention should anticipate funding for nonclinical components of the intervention, including coordination and monitoring, and consider how these activities can be performed most efficiently. For institutions without established telemedicine programs, selection of videoconferencing platforms and adequate staffing for participant technical support should be considered. Our step-by-step application of TDABC serves as a case study demonstrating how interventionists can gather data on resource use and costs of intervention activities concurrently with their collection of trial data.

An Ostomy Self-management Telehealth Intervention for Cancer Survivors: Technology-Related Findings From a Randomized Controlled Trial.

BACKGROUND: An Ostomy Self-management Telehealth (OSMT) intervention by nurse educators and peer ostomates can equip new ostomates with critical knowledge regarding ostomy care. A telehealth technology assessment aim was to measure telehealth engineer support requirements for telehealth technology-related (TTR) incidents encountered during OSMT intervention sessions held via a secure cloud-based videoconferencing service, Zoom for Healthcare. OBJECTIVE: This paper examines technology-related challenges, issues, and opportunities encountered in the use of telehealth in a randomized controlled trial intervention for cancer survivors living with a permanent ostomy. METHODS: The Arizona Telemedicine Program provided telehealth engineering support for 105 OSMT sessions, scheduled for 90 to 120 minutes each, over a 2-year period. The OSMT groups included up to 15 participants, comprising 4-6 ostomates, 4-6 peer ostomates, 2 nurse educators, and 1 telehealth engineer. OSMT-session TTR incidents were recorded contemporaneously in detailed notes by the research staff. TTR incidents were categorized and tallied. RESULTS: A total of 97.1% (102/105) OSMT sessions were completed as scheduled. In total, 3 OSMT sessions were not held owing to non-technology-related reasons. Of the 93 ostomates who participated in OSMT sessions, 80 (86%) completed their OSMT curriculum. TTR incidents occurred in 36.3% (37/102) of the completed sessions with varying disruptive impacts. No sessions were canceled or rescheduled because of TTR incidents. Disruptions from TTR incidents were minimized by following the TTR incident prevention and incident response plans. CONCLUSIONS: Telehealth videoconferencing technology can enable ostomates to participate in ostomy self-management education by incorporating dedicated telehealth engineering support. Potentially, OSMT greatly expands the availability of ostomy self-management education for new ostomates.

The Third National Telemedicine & Telehealth Service Provider Showcase Conference: Advancing Telehealth Partnerships.

INTRODUCTION: As telemedicine and telehealth services are experiencing increasing rates of adoption, industry leaders and healthcare service providers are becoming increasingly focused on human resource issues encountered in the delivery of a broad range of telehealth services. To create a forum for the discussion of many interrelated elements of telehealth service industry, a national conference entitled "Telemedicine & Telehealth Service Provider Showcase" (SPS) Conference was established in 2014, and repeated in 2016 and 2017, in Arizona. These SPS Conferences include thought leaders, telehealth service providers, government administrators, and academicians from leading programs addressing service provider workforce issues. METHODS: This report summarizes the content of SPS 2017 conference, held in Phoenix, AZ, October 2-3, 2017. The topics covered at SPS 2017 include using telehealth services as a strategic asset; development of appropriate effective partnerships; direct-to-consumer initiatives; important reimbursement, legislative, and regulatory issues (i.e., Centers for Medicare & Medicaid Services [CMS] approaches, financial models, and return on investment [ROI]); marketing; evaluation and applied metrics; remote monitoring and sensors; integration with electronic health records; and overall lessons learned. RESULTS: The content of SPS 2017 is summarized in the body of this report. The SPS 2017 program evaluators included attendees, speakers, and exhibitors. The knowledge attendees gained at SPS 2017 was characterized, by all three groups, as forward-looking and practical. CONCLUSION: SPS 2017 succeeded in identifying, and focusing on, solutions for issues, challenges, and barriers impacting the rapidly expanding telehealth service segment of the healthcare industry. The growing interest in this annual SPS Conference series apparently reflects, in part, the program committee's successes in identifying practical issues and their potential solutions.

The Empirical Foundations of Telepathology: Evidence of Feasibility and Intermediate Effects.

INTRODUCTION: Telepathology evolved from video microscopy (i.e., "television microscopy") research in the early 1950s to video microscopy used in basic research in the biological sciences to a basic diagnostic tool in telemedicine clinical applications. Its genesis can be traced to pioneering feasibility studies regarding the importance of color and other image-based parameters for rendering diagnoses and a series of studies assessing concordance of virtual slide and light microscopy diagnoses. This article documents the empirical foundations of telepathology. METHODS: A selective review of the research literature during the past decade (2005-2016) was conducted using robust research design and adequate sample size as criteria for inclusion. CONCLUSIONS: The evidence regarding feasibility/acceptance of telepathology and related information technology applications has been well documented for several decades. The majority of evidentiary studies focused on intermediate outcomes, as indicated by comparability between telepathology and conventional light microscopy. A consistent trend of concordance between the two modalities was observed in terms of diagnostic accuracy and reliability. Additional benefits include use of telepathology and whole slide imaging for teaching, research, and outreach to resource-limited countries. Challenges still exist, however, in terms of use of telepathology as an effective diagnostic modality in clinical practice.

Application and Utility of iPads in Pediatric Tele-echocardiography.

BACKGROUND: Telemedicine is used with increasing frequency to improve patient care in remote areas. The interpretation of medical imaging on iPad(®) (Apple, Cupertino, CA) tablets has been reported to be accurate. There are no studies on the use of iPads for interpretation of pediatric echocardiograms. We compared the quality of echo images, diagnostic accuracy, and review time using three different modalities: remote access on an iPad Air (iPad), remote access via a computer (Remote), and direct access on a computer linked through Ethernet to the server, the "gold standard" (Direct). MATERIALS AND METHODS: Fifty consecutive archived pediatric echocardiograms were interpreted using the three modalities. Studies were analyzed blindly by three pediatric cardiologists; review time, diagnostic accuracy, and image quality were documented. Diagnostic accuracy was assessed by comparing the study diagnoses with the official diagnosis in the patient's chart. Discrepancies between diagnoses were graded as major (more than one grade difference) or minor (one grade difference in severity of lesion). RESULTS: There were no significant differences in accuracy among the three modalities. There was one major discrepancy (size of patent ductus arteriosus); all others were minor, hemodynamically insignificant. Image quality ratings were better for iPad than Remote; Direct had the highest ratings. Review times (mean [standard deviation] minutes) were longest for iPad (5.89 [3.87]) and then Remote (4.72 [2.69]), with Direct having the shortest times (3.52 [1.42]) (p < 0.0001). CONCLUSIONS: Pediatric echocardiograms can be interpreted using convenient, portable devices while preserving accuracy and quality with slightly longer review times (1-2 min). These findings are important in the current era of increasing need for mobile health.

State medical licensure for telemedicine and teleradiology.

Physician medical licensure is state based for historical and constitutional reasons. It may also provide the best method for guaranteeing patient protection from unqualified, incompetent, impaired, or unprofessional practitioners of medicine. However, a significant cost for physicians practicing telemedicine is having to obtain multiple state medical licenses. There is reasonable likelihood that model legislation for the practice of telemedicine across state boundaries will be passed in the next few years, providing physicians with a simpler process for license reciprocity in multiple states via interstate licensing compacts. Physicians would have to be licensed in the state in which the patient resides. Patient complaints would still be adjudicated by the medical licensing board in the state where the patient resides according applicable state legislation.

Telephotography in trauma: a 2-year clinical experience.

INTRODUCTION: Smartphones can be used to record and transmit high-quality clinical photographs. The aim of this study was to describe our experience with smartphone telephotography in the care of trauma patients. We hypothesized that smartphone telephotography can be safely and effectively implemented on a trauma service. SUBJECTS AND METHODS: We performed a 2-year (January 2011-December 2012) prospective analysis of all patient photographs recorded by members of our trauma team at our Level I trauma center. All members of the trauma team recorded patient photographs and e-mailed them to a secure e-mail account. An administrative assistant uploaded a copy of each photgrapho into the patient's electronic medical record. We assessed the number of photographs collected and uploaded, as well as the success, failure, and complication rates. RESULTS: Our trauma team sent 7,200 photographs to a secure e-mail account. Of those, 6,120 (85%) were considered, after an initial review, to be of good quality. Of these, 3,320 photographs (54%) were successfully uploaded into a patient's electronic medical record; the remaining 2,800 photographs lacked adequate labeling and could not be uploaded. The average interval to uploading was 3 months. In total, 10 photographs were uploaded into the wrong patient's electronic medical record, for an error rate of 0.003%. We received only three complaints during the study period. CONCLUSIONS: Telephotography can be safely and effectively implemented in trauma clinical practice. Fears of Health Insurance Portability and Accountability Act violations are not valid, as the incidence of patient complaints is minimal when telephotography is implemented under strict guidelines and rules. Dedicated administrative personnel are essential for effective implementation of smartphone photography.

The empirical foundations of telemedicine interventions for chronic disease management.

The telemedicine intervention in chronic disease management promises to involve patients in their own care, provides continuous monitoring by their healthcare providers, identifies early symptoms, and responds promptly to exacerbations in their illnesses. This review set out to establish the evidence from the available literature on the impact of telemedicine for the management of three chronic diseases: congestive heart failure, stroke, and chronic obstructive pulmonary disease. By design, the review focuses on a limited set of representative chronic diseases because of their current and increasing importance relative to their prevalence, associated morbidity, mortality, and cost. Furthermore, these three diseases are amenable to timely interventions and secondary prevention through telemonitoring. The preponderance of evidence from studies using rigorous research methods points to beneficial results from telemonitoring in its various manifestations, albeit with a few exceptions. Generally, the benefits include reductions in use of service: hospital admissions/re-admissions, length of hospital stay, and emergency department visits typically declined. It is important that there often were reductions in mortality. Few studies reported neutral or mixed findings.

Telemedicine in an academic center--the Arizona Telemedicine Program.

This article provides background information on the history of telemedicine in Arizona and the Arizona Telemedicine Program (ATP). Following a brief overview of the growth of the ATP over the past 16 years, special focus is directed toward a description of the ATP business model, sustainability efforts of the Program, and ATP's future directions and goals. The ATP was established by the Arizona State Legislature in 1996 and, today, operates a large university-based statewide telemedicine consortium. It provides a spectrum of telemedicine support services to dozens of independent healthcare organizations throughout Arizona and bordering states. The ATP's backbone is a regional, 160-site dedicated healthcare and education broadband telecommunications network called the Arizona Telemedicine Network (ATN). The ATN is a fixed-cost network operated 24/7 by ATP engineers. In addition to providing access to the ATN, the ATP also provides its member individuals and organizations with benefits including biomedical communications services and expertise, telemedicine training on financial, legal, regulatory, and administrative support aspects, and access to subspecialty telemedicine consultation services.

Testing a top-down strategy for establishing a sustainable telemedicine program in a developing country: the Arizona telemedicine program-US Army-Republic of Panama Initiative.

OBJECTIVE: Many developing countries have shown interest in embracing telemedicine and incorporating it into their healthcare systems. In 2000, the U.S. Army Yuma Proving Ground (YPG) initiated a program to assist the Republic of Panama in establishing a demonstration Panamanian rural telemedicine program. YPG engaged the Arizona Telemedicine Program (ATP) to participate in the development and implementation of the program. MATERIALS AND METHODS: The ATP recommended adoption of a "top-down" strategy for creating the program. Early buy-in of the Panamanian Ministry of Health and academic leaders was regarded as critical to the achievement of long-term success. RESULTS: High-level meetings with the Minister of Health and the Rectors (i.e., Presidents) of the national universities gained early program support. A telemedicine demonstration project was established on a mountainous Indian reservation 230 miles west of Panama City. Today, three rural telemedicine clinics are linked to a regional Ministry of Health hospital for teleconsultations. Real-time bidirectional videoconferencing utilizes videophones connected over Internet protocol networks at a data rate of 768 kilobits per second to the San Felix Hospital. Telepediatrics, tele-obstetrics, telepulmonology, teledermatology, and tele-emergency medicine services became available. Telemedicine services were provided to the three sites for a total of 1,013 cases, with numbers of cases increasing each year. These three demonstration sites remained in operation after discontinuation of the U.S. involvement in September 2009 and serve as a model program for other telemedicine initiatives in Panama. CONCLUSIONS: Access to the assets of a partner-nation was invaluable in the establishment of the first model telemedicine demonstration program in Panama. After 3 years, the Panamanian Telemedicine and Telehealth Program (PTTP) became self-sufficient. The successful achievement of sustainability of the PTTP after disengagement by the United States fits the Latifi-Weinstein model for establishing telemedicine programs in developing countries.

Improving communication in level 1 trauma centers: replacing pagers with smartphones.

INTRODUCTION: Communication among healthcare providers continues to change, and 90% of healthcare providers are now carrying cellular phones. Compared with pagers, the rate and amount of information immediately available via cellular phones are far superior. Wireless devices such as smartphones are ideal in acute trauma settings as they can transfer patient information quickly in a coordinate manner to all the team members responsible for patient care. SUBJECTS AND METHODS: A questionnaire survey was distributed among all the trauma surgeons, surgery residents, and nurse practitioners who were a part of the trauma surgery team at a Level 1 trauma center. Answers to each question were recorded on a 5-point Likert scale. The completed survey questionnaires were analyzed using Statistical Package for Social Sciences software (SPSS version 17; SPSS, Inc., Chicago, IL). RESULTS: The respondents had an overall positive experience with the usage of the third-generation (3G) smartphones, with 94% of respondents in favor of having wireless means of communication at a Level 1 trauma center. Of respondents, 78% found the device very user friendly, 98% stated that use of smartphones had improved the speed and quality of communication, 96% indicated that 3G smartphones were a useful teaching tool, 90% of the individuals felt there was improvement in the physician's response time to both routine and critical patients, and 88% of respondents were aware of the rules and regulations of the Health Insurance Portability and Accountability Act. CONCLUSIONS: Smartphones in an acute trauma setting are easy to use and improve the means of communication among the team members by providing accurate and reliable information in real time. Smartphones are effective in patient follow-up and as a teaching tool. Strict rules need to be used to govern the use of smartphones to secure the safety and secrecy of patient information.

Video consultation for trauma and emergency surgical patients.

The saying goes that a picture is worth a thousand words, but what then is the value of video? For the care of trauma and emergency surgical patients, the use of video consultation between medical providers may be worth its weight in gold. Telemedicine has become an important tool in reducing the disparity among the haves and the have not's, in this case facilities with a trauma service and those without. This article presents the use of live video for trauma consultations between the only level 1 trauma center in Southern Arizona and several smaller rural hospitals. We also expand on what we believe the future and direction of telesurgery in the fields of critical care and trauma surgery.

Observer performance using virtual pathology slides: impact of LCD color reproduction accuracy.

The use of color LCDs in medical imaging is growing as more clinical specialties use digital images as a resource in diagnosis and treatment decisions. Telemedicine applications such as telepathology, teledermatology, and teleophthalmology rely heavily on color images. However, standard methods for calibrating, characterizing, and profiling color displays do not exist, resulting in inconsistent presentation. To address this, we developed a calibration, characterization, and profiling protocol for color-critical medical imaging applications. Physical characterization of displays calibrated with and without the protocol revealed high color reproduction accuracy with the protocol. The present study assessed the impact of this protocol on observer performance. A set of 250 breast biopsy virtual slide regions of interest (half malignant, half benign) were shown to six pathologists, once using the calibration protocol and once using the same display in its "native" off-the-shelf uncalibrated state. Diagnostic accuracy and time to render a decision were measured. In terms of ROC performance, Az (area under the curve) calibrated = 0.8570 and Az uncalibrated = 0.8488. No statistically significant difference (p = 0.4112) was observed. In terms of interpretation speed, mean calibrated = 4.895 s; mean uncalibrated = 6.304 s which is statistically significant (p = 0.0460). Early results suggest a slight advantage diagnostically for a properly calibrated and color-managed display and a significant potential advantage in terms of improved workflow. Future work should be conducted using different types of color images that may be more dependent on accurate color rendering and a wider range of LCDs with varying characteristics.

Remote diagnosis of congenital heart disease in southern Arizona: comparison between tele-echocardiography and videotapes.

OBJECTIVE: We report our experience with tele-echocardiography and echocardiograms recorded digitally or on videotape (recorded-echos) at The University of Arizona from August 2006 to December 2010 and compare their quality and diagnostic accuracy. MATERIALS AND METHODS: Tele-echocardiograms (tele-echos) were transmitted from the Yuma Regional Medical Center to The University of Arizona via a T-1 and aT-3 line at a bandwidth of 768 kilobits per second. Recorded-echos were shipped for interpretation to The University of Arizona by overnight mail. Diagnostic accuracy was assessed by comparing tele- and recorded-echos with electrocardiograms performed by a pediatric cardiologist (PedsCard-echos). RESULTS: Three hundred forty-six tele-echos in 260 patients and 455 recorded-echos in 406 patients were performed (median age, 6 and 8 days, respectively). Indications included possible congenital heart disease (CHD), patent ductus arteriosus (PDA), and persistent pulmonary hypertension of the newborn. Diagnostic categories included complex CHD, non-critical disease, PDA, and other. PedsCard-echos were available for 27% of the tele-echo and 30% of the recorded-echo patients. Comparisons between tele- and PedsCard-echo yielded no discrepancies in 12 (23%), expected resolution of condition in 26 (49%), and minor in 14 (26%). One (2%) major discrepancy was detected. Comparisons between recorded- and PedsCard-echo showed no discrepancies in 28 (40%), expected resolution of condition in 14 (20%), and minor discrepancies in 28 (40%) patients. No significant difference with respect to discrepancies was detected between tele- and recorded-echos. There was significant (p<0.01) improvement in tele- and recorded-echo study quality by 2010. CONCLUSIONS: (1) Tele-echocardiography can be performed successfully with excellent accuracy. (2) The quality of tele- and recorded-echo studies improved toward the end of the analysis period. (3) Although initially tele-echo studies were more accurate than recorded-echo studies, there was no difference between these two types of studies by the fourth year of the study. (4) Both tele- and recorded-echos were indispensible in the remote diagnosis of CHD.
