Abstract
Digital Pathology (also referred to as Telepathology and Whole Slide Imaging) is the process of producing high resolution digital images from tissue sections on glass slides. These glass slides are normally examined under a microscope by a pathologist as part of the diagnostic process. The emergence of digital pathology now means that digital images are stored on secure servers and can be viewed on computer monitors; enabling pathologists to work remotely and to collaborate with other colleagues when second opinions are needed. The implementation of digital pathology into clinical practice has many potential benefits. Although this has been long recognised, its adoption as a diagnostic tool remains low and pathologists’ projections about its future deployment are cautious. Notable early digital pathology adopters have led the way. The challenge now is to scale-up digital pathology beyond the relatively few large networks and centres of excellence. Many other areas of healthcare have accumulated experience about optimising approaches to digital health/healthcare technology deployment and sustainability. This has been done in a multi-disciplinary context and has applied theoretical/conceptual frameworks. Thus far there has been little use of similar frameworks in the planning of digital pathology deployment in clinical practice. In this essay, I will explore the scope of digital pathology implementation approaches that have been deployed in clinical practice and examine what can be learned from the wider healthcare experience of adopting, scaling-up and sustaining innovative healthcare solutions.

Abstract
INTRODUCTION Telehealth is an increasingly popular treatment delivery modality for mental healthcare, including evidence-based treatment for complex and intense psychopathologies such as post-traumatic stress disorder (PTSD). Despite the growing telehealth literature, there is a need for more confirmatory research on satisfaction with PTSD telehealth treatment, particularly among veterans, for whom the most rapid and permanent expansion of telehealth services has been implemented through the Department of Veterans Affairs. METHODS The current paper integrates data from two concurrent PTSD treatment outcome studies that compared prolonged exposure therapy delivered both in person and via telehealth for veterans (N = 140). Using two different measures of satisfaction (the Charleston Psychiatric Outpatient Satisfaction Scale-Veteran Affairs Version (CPOSS) and the Service Delivery Perception Questionnaire (SDPQ)), we hypothesized that PTSD improvement would predict satisfaction, but that delivery modality (in person vs telehealth) would not. RESULTS Results only partially supported the hypotheses, in that PTSD symptom improvement was associated with greater satisfaction, and in-person treatment modality was associated with satisfaction as measured by the CPOSS (but not the SDPQ). Subgroup differences by sex were found, such that male veterans, typically with combat-related trauma, were more satisfied with their PTSD treatment compared to female veterans, who were most frequently seen in this study for military sexual trauma. DISCUSSION Altogether, results illustrate a need for additional satisfaction studies with diverse samples and large sample sizes. Future research may benefit from examining satisfaction throughout treatment, identifying predictors of greater PTSD improvement, and further examining demographic subgroups.

Use of telehealth for facilitating the diagnostic assessment of Autism Spectrum Disorder (ASD): A scoping review. PLoS One 2020; 15:e0236415. [PMID: 32702017 PMCID: PMC7377392 DOI: 10.1371/journal.pone.0236415] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Accepted: 07/06/2020] [Indexed: 12/13/2022] Open
Abstract
There is a significant delay between seeking help and a confirmed diagnosis of Autism Spectrum Disorder (ASD). This delay can lead to poor outcomes for both the families and individuals. Telehealth potentially offers a way of improving the diagnostic pathway for ASD. We conducted a scoping review examining which telehealth approaches are used in the diagnosis and assessment of ASD in children and adults, whether they are feasible and acceptable, and how they compare with face-to-face diagnosis and assessment methods. A search for all peer-reviewed articles, combining the terms of autism and telehealth was conducted from 2000 to 2019. A total of 10 studies were identified for inclusion in the review. This review of the literature found there to be two methods of using telehealth: (a) Real-Time method e.g. video conferencing that enables teams in different areas to consult with the families and to assess the child/adult in real time and (b) A Store-and-Forward method as Naturalistic Observation Diagnostic Assessment (NODA) system to upload videos of child’s behaviors to a webportal that enables the clinicians to make an assessment remotely. The findings were positive, finding there to be high agreement in terms of the diagnosis between remote methods and face to face methods and with high levels of satisfaction among the families and clinicians. This field is in the very early stages and so only studies with small sample size using surveys and interviews were identified but the findings suggest that there is potential for telehealth methods to improve access to assessment and diagnosis of ASD used in conjunction with existing methods, especially for those with clear autism traits and adults with ASD. Larger randomised controlled trials of this technology are warranted.

Abstract
Military families experience unique stressful circumstances such as frequent moves, service-related physical and mental health difficulties, and separation from support. Although many families exhibit high resilience in response to these stressors, military children are at an increased risk for emotional and behavioral difficulties, exposure to intimate partner violence, and child maltreatment. These potential problems not only affect child functioning, but often also negatively impact family and veteran outcomes. Although the Department of Defense has enhanced efforts to address child and family trauma among military families, many veterans' families are still not receiving timely, evidence-based treatment. With many veterans receiving care through Veterans Affairs (VA) medical centers, incorporating family treatment into VA services is important for promoting optimal veteran outcomes. Trauma-focused cognitive-behavioral therapy (TF-CBT) has been used successfully for civilian and military children exposed to trauma including child maltreatment, intimate partner violence, and traumatic grief. This article reviews research regarding veterans' mental health, child and family functioning, and parenting, and highlights the value of implementing TF-CBT in the VA given its family and-resilience-focused structure, strong empirical support, and flexible delivery model. Strengths of delivering TF-CBT in the VA (e.g., provision of trauma services for families where veterans are already receiving care, family education about trauma), as well as implementation barriers (e.g., VA policy regarding veteran-focused treatment, reduced facility resources) are discussed. Finally, future research directions are proposed, including mixed-methods research with veterans' families to investigate the effectiveness and feasibility of TF-CBT dissemination within VA facilities.

[PMID: 29759085 PMCID: PMC5952632 DOI: 10.1186/s13000-018-0705-0] [Citation(s) in RCA: 21] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2017] [Accepted: 04/27/2018] [Indexed: 11/13/2022] Open
Abstract
Background Telepathology (TP) provides remote pathology services for primary diagnosis practices, including intraoperative consultation of surgical pathology; it has not been widely implemented in China. In this study, the results of an implementation were reported, which lasted for two and a half years, and demonstrated the experience of the diagnosis of the intraoperative frozen sections by using TP consultation platform of Southern Medical University and Guangzhou Huayin Medical Laboratory Center (SMU-HUAYIN TP) in China. Methods The SMU-HUAYIN TP consultation platform connects 71 participating basic hospitals and 11 senior pathologists. Nanfang Hospital is a high-level hospital located in a large city in China. This retrospective study summarizes the experience and results of TP for frozen section diagnosis by comparing the data of the platform and Nanfang Hospital over a period of 2.5 years from January 2015 to June 2017. Results A total of 5233 cases were submitted to the platform, including 1019 cases in 2015, 2320 cases in 2016, and 1894 cases in 2017. The most common cases were breast (30.42%), followed by thyroid (29.05%) and gynecological (24.86%). Average turn-around time (TAT) of the cases from the platform in 2015 and 2016 was controlled within 30 min. In most TP cases (90.31%) and cases from Nanfang Hospital (86.14%), a definitive diagnosis was provided. The coincidence rate was 99.77% in the TP cases and 99.35% in the cases from Nanfang Hospital. The false positive and false negative rates of TP cases were 0.04 and 0.19%, respectively and no significant difference was found among different senior pathologists (P = 0.974, P = 0.989, P > 0.05). Similarly, there was no significant difference between TP cases and cases from Nanfang Hospital that were diagnosed by the same senior pathologist (P > 0.05). Conclusions Our results indicate that TP in frozen section diagnosis could improve patient care and solve the problem of unevenly distributed pathology resources in China. We believe that in the near future, TP in frozen section diagnosis will become an important component of telemedicine and will play a significant role in health care reform in China.

Abstract
BACKGROUND The aim of this study is to investigate and compare the results of digital image analysis in pleural effusion cytology samples with conventional modalities. MATERIALS AND METHODS In this cross-sectional study, 53 pleural fluid cytology smears from Qaem hospital pathology department, located in Mashhad, Iran were investigated. Prior to digital analysis, all specimens were evaluated by two pathologists and categorized into three groups as: benign, suspicious, and malignant. Using an Olympus microscope and Olympus DP3 digital camera, digital images from cytology slides were captured. Appropriate images (n = 130) were separately imported to Adobe Photoshop CS5 and parameters including area and perimeter, circularity, Gray Value mean, integrated density, and nucleus to cytoplasm area ratio were analyzed. RESULTS Gray Value mean, nucleus to cytoplasm area ratio, and circularity showed the best sensitivity and specificity rates as well as significant differences between all groups. Also, nucleus area and perimeter showed a significant relation between suspicious and malignant groups with benign group. Whereas, there was no such difference between suspicious and malignant groups. CONCLUSION We concluded that digital image analysis is welcomed in the field of research on pleural fluid smears as it can provide quantitative data to apply various comparisons and reduce interobserver variation which could assist pathologists to achieve a more accurate diagnosis.

Abstract
We must include rural participants in health-related research if we are to address health-related disparities and inequity, particularly in mental health. However, the first step of the research process, in person, witnessed, signed informed consent is often a limiting factor and insurmountable barrier to precisely the type of research (e.g., telehealth) designed to overcome barriers of geographic distance and travel time. Telehealth, or the provision of medical care or services to patients by means of audio/video and procedure-specific technology, addresses some barriers to health created by rurality by making health care professionals more accessible to patients. A logical complement to telehealth is "teleconsent." Teleconsent can be defined as using remote, facial integrated identity verification to allow (a) remote guidance of participants through consent documents, and (b) digital signing by all parties, obviating the need for in person signed consent. The ability to review and sign consent documents via telehealth with synchronous viewing is a novel, innovative means by which to overcome the initial significant barrier to recruitment of rural participants into healthcare research. By leveraging the growing capabilities of telehealth, teletailoring studies can improve the efficiency of research recruitment and facilitate the consent process for under-represented populations in research. Strategies for implementation are clearly relevant to increasing the success of clinical trial recruitment.

Abstract
BACKGROUND Coordination between physicians and allied professionals is essential to the effective delivery of care services and is associated with positive patient outcomes. As information technology can radically transform how professionals collaborate, both researchers and healthcare accreditation bodies are devoting a growing interest to the means of achieving better coordination. INTRODUCTION The primary aim of this study is to explain the extent to which and how coordination practices between pathologists, technologists, and surgeons are transformed when telepathology is being implemented. MATERIALS AND METHODS An interpretive case study was conducted. A total of 60 semistructured interviews with key participants were conducted, in addition to several days of direct observation of telepathology-based intraoperative consultations (IOCs). RESULTS Three major kinds of transformation of coordination practices were observed. First, the telepathology system itself constrains and disrupts coordination routines, such as the presentation of slides. Second, anticipating IOC, proactively performed by the laboratory personnel in traditional settings, requires more formal requests in a telepathology context. Third, local technologists become more autonomous in performing complex macroscopy manipulations and managing the laboratory tasks traditionally performed by pathologists. CONCLUSIONS Successful coordination of work in a telepathology-based IOC context requires that significant transformations be anticipated and accounted for. Project managers need to formalize new work processes, support the transformations in professional roles, and mitigate the major hindrances that small material changes may have on work routines.

Abstract
Background: Post-traumatic stress disorder (PTSD) is a highly prevalent and impairing condition for which there are several evidence-based psychotherapies. However, a significant proportion of patients fail to complete a ‘sufficient dose’ of psychotherapy, potentially limiting treatment gains. Aims: The present study investigated predictors of premature treatment discontinuation during a trial of prolonged exposure (PE) therapy for PTSD. Method: Combat veterans with PTSD were recruited to participate in a randomized clinical trial of PE delivered in person or via telehealth technologies. Of the 150 initial participants, 61 participants discontinued the trial before the completion of eight sessions (of an 8‒12 session protocol). Treatment condition (telehealth or in person) and factors identified by prior research (age, combat theatre, social support, PTSD symptoms) were tested as predictors of treatment discontinuation. Results: A Cox proportional hazards model (a subtype of survival analysis) was used to evaluate predictors of treatment discontinuation. Disability status and treatment condition were identified as significant predictors of discontinuation, with a noted disability and use of telehealth demonstrating higher risk. Conclusions: The present findings highlight the influence of telehealth and disability status on treatment discontinuation, while minimizing the role of the previously identified variables from studies with less sensitive analyses.

Abstract
Introduction Although there is growing support that evidence-based psychotherapies (EBPs) delivered in-person and through telehealth are equivalent in terms of symptom reduction for posttraumatic stress disorder (PTSD), there has been far less investigation comparing these treatment modalities in terms of patient satisfaction. The present study investigated participant satisfaction and perception of the quality of service delivery within a clinical trial comparing the delivery of an EBP, Prolonged Exposure (PE) for PTSD, through home-based telehealth and in-person services. Methods Veterans ( N = 67) with PTSD were randomized to receive PE via video telehealth technology ( n = 27) or via in-person delivery ( n = 40). Participants completed service demographic questions, PTSD symptom assessments, and satisfaction and service delivery perception questionnaires. Results Analyses of covariance were used to investigate the influence of treatment modality on patient satisfaction and perceived quality of service delivery, while controlling for demographics and PTSD symptoms. No differences were observed on the majority of measures, with the exception of participants in the telehealth condition endorsing willingness to drive further for telehealth services as compared with participants in the in-person condition. Discussion Findings illustrate participant satisfaction and acceptance of EBPs delivered via telehealth at a level consistent with that of in-person services. Preliminary findings suggest that the experience of receiving telehealth services may be associated with increased willingness to participate in telehealth services again. Together, these findings of patient satisfaction and acceptance of telehealth services support the ongoing delivery of EBPs via telehealth as well as their future expansion.

Abstract
CONTEXT Telepathology is a particular form of telemedicine that fundamentally alters the way pathology services are delivered. Prior reviews in this area have mostly focused on 2 themes, namely technical feasibility issues and diagnosis accuracy. OBJECTIVES To synthesize the literature on telepathology implementation challenges and broader organizational and societal impacts and to propose a research agenda to guide future efforts in this domain. DATA SOURCES Two complementary databases were systematically searched: MEDLINE (PubMed) and ABI/INFORM (ProQuest). Peer-reviewed articles and conference proceedings were considered. The final sample consisted of 159 papers published between 1992 and 2013. CONCLUSIONS This review highlights the diversity of telepathology networks and the importance of considering these distinctions when interpreting research findings. Various network structures are associated with different benefits. Although the dominant rationale in single-site projects is financial, larger centralized and decentralized telepathology networks are targeting a more diverse set of benefits, including extending access to pathology to a whole region, achieving substantial economies of scale in workforce and equipment, and improving quality by standardizing care. Importantly, our synthesis reveals that the nature and scale of encountered implementation challenges also varies depending on the network structure. In smaller telepathology networks, organizational concerns are less prominent, and implementers are more focused on usability issues. As the network scope widens, organizational and legal issues gain prominence.

Abstract
CONTEXT Microbiology laboratories are continually pursuing means to improve quality, rapidity, and efficiency of specimen analysis in the face of limited resources. One means by which to achieve these improvements is through the remote analysis of digital images. Telemicrobiology enables the remote interpretation of images of microbiology specimens. To date, the practice of clinical telemicrobiology has not been thoroughly reviewed. OBJECTIVE To identify the various methods that can be employed for telemicrobiology, including emerging technologies that may provide value to the clinical laboratory. DATA SOURCES Peer-reviewed literature, conference proceedings, meeting presentations, and expert opinions pertaining to telemicrobiology have been evaluated. CONCLUSIONS A number of modalities have been employed for telemicroscopy, including static capture techniques, whole slide imaging, video telemicroscopy, mobile devices, and hybrid systems. Telemicrobiology has been successfully implemented for several applications, including routine primary diagnosis, expert teleconsultation, and proficiency testing. Emerging areas of telemicrobiology include digital plate reading of bacterial cultures, mobile health applications, and computer-augmented analysis of digital images. To date, static image capture techniques have been the most widely used modality for telemicrobiology, despite newer technologies being available that may produce better quality interpretations. Telemicrobiology adds value, quality, and efficiency to the clinical microbiology laboratory, and increased adoption of telemicrobiology is anticipated.

Abstract
Digital plate reading (DPR) is increasingly being adopted as a means to facilitate the analysis and improve the quality and efficiency within the clinical microbiology laboratory. This review discusses the role of DPR in the context of total laboratory automation and explores some of the platforms currently available or in development for digital image capturing of microbial growth on media. The review focuses on the advantages and challenges of DPR. Peer-reviewed studies describing the utility and quality of these novel DPR systems are largely lacking, and professional guidelines for DPR implementation and quality management are needed. Further development and more widespread adoption of DPR is anticipated.

Abstract
OBJECTIVES Telehealth technology may reduce the effect of treatment barriers and improve participation in treatment for veterans with posttraumatic stress disorder (PTSD). The present study is an ongoing randomized controlled trial comparing the effectiveness of prolonged exposure (PE) delivered via in person or home-based video telehealth modalities. METHOD A total of 52 veterans with combat-related PTSD were randomized to receive 8-12 weeks of PE through either home-based telehealth or standard in-person office-based care. RESULTS Participants evinced significant reductions in symptoms of PTSD, depression, and anxiety from pre- to posttreatment across both conditions. Analyses conducted within a noninferiority framework suggested nonsignificant treatment outcome differences in clinician-reported PTSD and self-reported anxiety between the conditions. Results were inconclusive for self-reported PTSD and depression symptoms. Patient satisfaction ratings did not significantly differ between the two groups. CONCLUSIONS Results suggest that PE can be delivered via home-based telehealth with outcomes and satisfaction ratings comparable to in-person practices for certain symptoms, however additional research is needed. This modality has the potential to address stigma- and geographic-related barriers to treatment, such as travel time and cost.

Abstract
Despite the high prevalence and potentially disabling consequences of mental disorders, specialized mental health services are extremely deficient, leading to the so-called 'Mental Health Gap'. Moreover, the services are concentrated in the urban areas, further worsening the rural-urban and tertiary primary care divide. Strengthening of and expanding the existing human resources and infrastructure, and integrating mental health into primary care appear to be the two major solutions. However, both the strategies are riddled with logistic difficulties and have a long gestation period. In such a scenario, telepsychiatry or e-mental health, defined as the use of information and communication technology to provide or support psychiatric services across distances, appears to be a promising answer. Due to its enormous potential, a review of the existing literature becomes imperative. An extensive search of literature was carried out and has been presented to delineate the modes of communication, acceptability and satisfaction, reliability, outcomes, cost-effectiveness, and legal and ethical challenges related to telepsychiatry. Telepsychiatry has been applied for direct patient care (diagnosis and management), consultation, and training, education, and research purposes. Both real-time, live interaction (synchronous) and store-forward (asynchronous) types of technologies have been used for these purposes. A growing amount of literature shows that training, supervision, and consultation by specialists to primary care physicians through telepsychiatry has several advantages. In this background, we have further focused on the models of telepsychiatry best suited for India, considering that mental health care can be integrated into primary care and taken to the doorstep of patients in the community.

Abstract
Background: There is a need for telemedicine, particularly in countries with large geographical areas and widely scattered low-density communities as is the case of the Canadian system, particularly if equality of care is to be achieved or the difference gap is to be narrowed between urban centers and more peripheral communities. Aims: 1. To validate teledermatopathology as a diagnostic tool in under-serviced areas; 2. To test its utilization in inflammatory and melanocytic lesions; 3. To compare the impact of 20× (0.5 μm/pixel) and 40× (0.25 μm/pixel) scans on the diagnostic accuracy. Materials and Methods: A total of 103 dermatopathology cases divided into three arms were evaluated by two pathologists and results compared. The first arm consisted of 79 consecutive routine cases (n=79). The second arm consisted of 12 inflammatory skin biopsies (n=12) and the third arm consisted of 12 melanocytic lesions (n=12). Diagnosis concordance was used to evaluate the first arm. Whereas concordance of preset objective findings were used to evaluate the second and third arms. Results: The diagnostic concordance rate for the first arm was 96%. The concordance rates of the objective findings for the second and third arms were 100%. The image quality was deemed superior to light microscopy for 40× scans. Conclusion: The current scanners produce high-resolution images that are adequate for evaluation of a variety of cases of different complexities.

Abstract
Recent research has focused on the effectiveness of evidence-based psychotherapy delivered via telehealth services. Unfortunately to date, the majority of studies employ very small samples and limited predictor and moderator variables. To address these concerns and further replicate and extend the literature on telehealth, the present study investigated the effectiveness of 12-session exposure therapy delivered either via telehealth (n=62) or in person (n=27) in veterans with posttraumatic stress disorder (PTSD). Findings demonstrated that although older veterans and Vietnam veterans were more likely to complete the telehealth treatment, telehealth findings were not influenced by patient age, sex, race, combat theater, or disability status. Exposure therapy delivered via telehealth was effective in reducing the symptoms of PTSD, anxiety, depression, stress, and general impairment with large effect sizes. Interestingly, exposure therapy via telehealth was less effective than exposure therapy delivered in person; however, lack of random assignment to condition limits conclusions of differential effectiveness. Overall, these findings support the utility of telehealth services to provide effective, evidence-based psychotherapies.

Abstract
Although telepathology (TP) has not been widely implemented for primary frozen section diagnoses, interest in its use is growing as we move into an age of increasing subspecialization and centralization of pathology services. University Health Network is a 3-site academic institution in downtown Toronto. The pathology department is consolidated at its Toronto General Hospital (TGH) site. The Toronto Western Hospital (TWH), located 1 mile to west of TGH, has no on-site pathologist, and generates 5 to 10 frozen section cases per week. More than 95% of these frozen sections are submitted by neurosurgeons, in most cases to confirm the presence of lesional tissue and establish a tissue diagnosis. In 2004, we implemented a robotic microscopy (RM) TP system to cover these frozen sections. In 2006, we changed to a virtual slide (VS) TP system. Between November 2004 and September 2006, 350 primary frozen section diagnoses were made by RM. An additional 633 have been reported by VS TP since October 2006, giving a total of 983 frozen sections from 790 patients. Of these cases, 88% have been single specimens with total turnaround times averaging 19.98 and 15.68 minutes per case by RM and VS TP, respectively (P < .0001). Pathologists required an average of 9.65 minutes to review a slide by RM. This decreased 4-fold to 2.25 minutes after the change to VS TP (P < .00001). Diagnostic accuracy has been 98% with both modalities, and our overall deferral rate has been 7.7%. Midcase technical failure has occurred in 3 cases (0.3%) resulting in a delay, where a pathologist went to TWH to report the frozen section. Discrepant cases have typically involved minor interpretive errors related to tumor type. None of our discrepant TP diagnoses has had clinical impact to date. We have found TP to be reliable and accurate for frozen section diagnoses. In addition to its superior speed and image quality, the VS approach readily facilitates consultation with colleagues on difficult cases. As a result, there has been greater overall pathologist satisfaction with VS TP.

Abstract
Up to a few years ago, the management of the information on the slides (virtual slides) in telepathology applications was principally based on the design and construction of a few identical and expensive platforms with microscope units and software tools for the display and for electronic control (zooming, moving, and cutting of images). The development of information technology tools allows the diffusion of new visualization strategies and the availability of low cost or free visualization proprietary tools. New competitive systems such as client-server architectures are available in telepathology today. The investigation of the new technologies for telepathology is a basic and core aspect in telemedicine technology assessment. A new interactive environment to investigate the health technology assessment of a telepathology system has been studied. In particular, in consideration of previous experience the methodology focused both on the senior pathologist and younger student pathologist. Two interactive forms were created by a working group: a feedback form and a diagnostic form. The first was designed to investigate the technology characteristics and acceptance of the telepathology systems. The second tool was designed to investigate the diagnostic accuracy on a significant sample of virtual slides by two different groups of pathologists (senior and younger students). The acceptance of the methodology was very high.

Abstract
Telemedicine has garnered significant attention over the past decade as a solution to cost and access challenges facing healthcare. Yet, utilization rates have not reached their full potential. One major barrier to the adoption of telemedicine cited in the literature is the lack of universal reimbursement from private payers. The purpose of this investigation was to capture a current picture of private reimbursement for telemedicine services in the United States. This investigation was a follow-up to a 2003 survey conducted by the American Telemedicine Association (ATA) and AMD Telemedicine. Representatives from 116 telemedicine programs were contacted between September and November 2005 via telephone and/or e-mail to participate in this survey. Of those contacted, we received responses from 64 organizations, a 55% response rate. To provide answers to our research questions, descriptive statistics were used for data analysis. Data indicate that the United States is progressing toward expanded private reimbursement for telemedicine services with 58% of responding organizations who provide potentially billable telemedicine services receiving private reimbursement (up 5% from 2003). In addition, it was found that 81% of those who receive private pay reported no differences between reimbursement for telemedicine services as compared to traditional faceto-face consults. Finally, of those who receive private pay, data indicated that telemedicine programs are submitting on average approximately 40% of consults for private reimbursement. While this investigation does suggest that we are making small improvements in private payer reimbursement, the change appears to lag behind a pace needed to optimize telemedicine deployment.

Abstract
BACKGROUND Diagnosis of pancreatic lesions can be accurately performed by endoscopic ultrasound guided fine needle aspiration (EUS-FNA) with onsite cytopathologists to assess specimen adequacy and to determine a preliminary diagnosis. Considerable time is needed to perform on-site assessments. This takes away work time of cytopathologists and prohibits them from serving remote locations. It is therefore logical to ask if real-time telecytopathology could be used to assess specimen adequacy and if telecytopathology diagnosis has the same level of agreement to the final diagnosis as that of onsite evaluation. In this study, we compare agreement between cytodiagnoses rendered using telecytopathology with onsite and final interpretations. METHOD 40 Diff-Quik-stained EUS-FNA were re-evaluated retrospectively (patient ages 31-62, 19:21 male:female, 15 non-malignant lesions, 25 malignant lesions as classified by final diagnosis). Each previously assessed by a cytopathologist and finally reviewed by the same or different cytopathologist. Blinded to the final diagnosis, a resident pathologist re-screened all slides for each case, selected a slide and marked the diagnostic cells most representative of the lesion. Blinded to the diagnosis, one cytopathologist assessed the marked cells through a real time remotely operated telecytopathology system (MedMicroscopy). Diagnosis and time spent were recorded. Kappa statistic was used to compare agreements between telecytopathology vs. original onsite vs. final diagnoses. RESULTS Time spent for prescreening ranged from 1 to 5 minutes (mean 2.6 +/- 1.3 minutes) and time spent for telecytopathology diagnosis ranged from 2-20 minutes (mean 7.5 +/- 4.5 minutes). Kappa statistics, K, was as follows: telecytopathology versus onsite diagnosis K, 95% CI = 0.65, 0.41-0.88, for telecytopathology versus final K, 95% CI = 0.61, 0.37-0.85 and for onsite diagnosis versus final K, 95% CI = 0.79, 0.61-0.98. There is no significant difference in agreement between onsite and telecytopathology diagnoses. Kappa values for telecytopathology were less than onsite evaluation when compared to the final diagnosis; however, the difference was not statistically significant. CONCLUSION This retrospective study demonstrates the potential use of telecytopathology as a valid substitute for onsite evaluation of pancreatic carcinoma by EUS-FNA.

Abstract
This paper examines the potential effects of using video-conferencing within the field of mental health in the UK. In order to assess the usefulness of telepsychiatric services, an electronic search was conducted for articles published between August 1998 and July 2006 using the MEDLINE, EMBASE, PsychINFO and Telemedicine and Information Exchange (TIE) databases. The search was carried out using the following terms: telepsychiatry, videoconferencing and telepsychology. A total of 178 articles were identified and based on review of the abstracts 72 were identified as being specific to efficacy, cost-effectiveness and satisfaction with psychiatric services delivered via videoconferencing. This paper concludes that the use of video conferencing can enhance psychiatric services within the UK especially for those patients who live in rural areas. Current advances in technology make this an increasingly more reliable and cost-effective method for assessing patients. The limitations of telemedicine are discussed and it is clear that this type of care is not suitable for all patients. Further research is required to assess the types of patients that telepsychiatry is most suitable for.

Abstract
Telepathology is the process of diagnostic histopathology performed on digital images viewed on a display screen rather than by conventional glass slide light microscopy. The technology of telepathology has radically improved over the past 5 years so that it is no longer the limiting factor in the diagnostic process. This review looks at the resources needed for dynamic and static telepathology, including image quality, computers and software interfaces, means of transmission and human resources. It critically analyses 32 published trials of telepathology, including some large prospective studies, in all areas of diagnostic histopathology including intraoperative frozen sections, routine and referral cases. New developments, including internet solutions and virtual microscopy, are described and there is analysis of the economics of telepathology within health care systems. The review concludes that all the necessary technology for telepathology is available, there is strong published evidence for a diagnostic accuracy comparable with glass slide diagnosis, in many contexts there is a clear-cut economic argument in favour of telepathology, and that the technique should now be integrated into mainstream diagnostic histopathology.

Abstract
To achieve real-time connectivity between its 8 hopital-based laboratories, Veterans Integrated Service Network (VISN) 12, headquartered in Chicago, IL, has implemented a hybrid dynamic store-and-forward (HDSF) telepathology network that extends across portions of 3 states. The majority of diagnostic telepathology functions are provided to the 3 hospitals (Iron Mountain, MI; Tomah, WI; and North Chicago, IL), which lack on-site pathologists and are serviced by the 4 pathologists located in Milwaukee, WI. In surgical pathology, routine primary diagnosis, frozen section diagnosis, and clinical consultation are provided with telepathology. In addition, autopsy and specialty clinical conferences are frequently performed by using telepathology. Telepathology has been applied to a variety of areas within clinical pathology as well, including protein electrophoresis, immunoelectrophoresis, peripheral blood smears, body fluids, microbiology, and distance learning. Implementation of telepathology has allowed VISN 12 to reach the goal of providing a single standard of accurate and timely pathology service, even at small sites that lack an on-site pathologist.

Abstract
We studied a series of 60 telepathology cases sent in consultation to the Department of Hematopathology from January 1, 1995, through July 31, 2000. Cases from the United States and the world representing academic, private, military, and federal sectors were reviewed. Ninety percent of patients were adults (54 of 60), and male patients outnumbered female patients 2 to 1. Ages were from 1 to 79 years (mean, 42 years). Forty-three cases were lymph nodes (72%), 14 were bone marrow or peripheral blood (23%), and 3 were from other sites (5%). Twenty-seven of the consultant diagnoses were benign (27 of 60). Twenty-nine were malignant (non-Hodgkin lymphoma, Hodgkin disease, and "other malignancy" groups), and 4 were nondiagnostic. Glass slide/paraffin tissue blocks were available in only 35 (58%) of 60 cases. The concordance rate for diagnostic telehematopathology cases with subsequent glass slide/paraffin block follow-up was 91% (29 of 32 cases). The discordance rate was 9% (3 of 32). This finding shows a high degree of diagnostic accuracy for consultative telehematopathology. Of 118 images analyzed, 58 were considered very good/good (49%), 32 were poor/very poor (27%), and 28 were fair (24%). Poor images had suboptimal resolution, color, or technical quality of transmission, and most poor images were low-power images. Additional case problems included insufficient immunoperoxidase stain availability, selection, and labeling; transmitted field selection; specimen preparation and staining; presence or absence of accompanying clinical data; and availability of ancillary studies such as flow cytometric, cytogenetic, and molecular data. From this analysis, the following recommendations are offered. To optimize telehematopathology consultation, include any additional information that have a significant influence on the final consultant diagnosis. Include any pertinent clinical information, laboratory data, special stains, immunoperoxidase stains, and molecular data. Select representative and diagnostically significant low-power and high-power fields for an accurate diagnosis. Label every immunostain or special stain submitted. Always send glass slides and tissue blocks when requested by the consultant. Optimize telemedicine microscopy and computer equipment with appropriate technical expertise, training, and support. In conclusion, the field of telepathology offers an exciting and potentially powerful solution to the problem of national and global subspecialty consultation. Hematopathology is potentially well suited to this technologically advanced marriage of computer and Internet technologies with modern microscopy, molecular diagnostics, immunophenotypic profiling, and the consultant pathologist.

Abstract
Telepathology is the use of telecommunications technology as a means to facilitate transfer of image-rich pathology data between remote locations for the purposes of diagnosis, education, and research. Although varying levels of technology exist to accomplish this task, static image--based systems are currently the most widely used around the world. Field selection and image quality have often been identified as major impediments to the successful use of static images for diagnostic telepathology. Between November 1994 and July 1999, the Armed Forces Institute of Pathology (AFIP) performed electronic consultation on over 1,250 static image--based cases, recording a clinically significant concordance rate of 97.3% between telepathology and final diagnosis (in cases in which follow-up material was available). For the same subset of cases, an absolute concordance rate of 73.7% was attained. A review of the case flow and construction of the AFIP telepathology system is presented, as well as factors that have an impact on the diagnostic accuracy of static image-based telepathology sytems in general.

Abstract
Telepathology is the practice of pathology at a distance by using video imaging and telecommunications. Significant progress has been made in telepathology. To date, 12 classes of telepathology systems have been engineered. Rapid and ultrarapid virtual slide processors may further expand the range of telepathology applications. Next-generation digital imaging light microscopes, such as miniaturized microscope arrays (MMA), may make virtual slide processing a routine laboratory tool. Diagnostic accuracy of telepathology is comparable with that of conventional light microscopy for most diagnoses. Current telepathology applications include intraoperative frozen sections services, routine surgical pathology services, second opinions, and subspecialty consultations. Three telepathology practice models are discussed: the subspecialty practice (SSP) model; the case triage practice (CTP) model; and the virtual group practice (VGP) model. Human factors influence performance with telepathology. Experience with 500 telepathology cases from multiple organs significantly reduces the video viewing time per case (P < .01). Many technology innovations can be represented as S-curves. After long incubation periods, technology use and/or efficiency may accelerate. Telepathology appears to be following an S-curve for a technical innovation.
