Increasing access to care via tele-health: the Arizona experience

The Arizona Telemedicine Program (ATP) is a large, multidisciplinary, university-based program that provides telemedicine services, distance learning, informatics training, and telemedicine technology assessment capabilities to communities throughout Arizona. The types of teleconsultation services available include real-time and store-forward consultations, continuing medical education, and patient information sessions. Since the inception of the ATP, there have been 97,722 telemedicine events. The most frequently used telemedicine service is teleradiology, comprising 85,728 teleconsults. Next in frequency are teledermatology and telepsychiatry consultations. Results of patient satisfaction surveys indicate high levels of patient satisfaction with both real-time and store-forward consultations. Three studies of the efficacy of telemedicine services are discussed. One study of the efficacy and diagnostic accuracy of utilizing telecolposcopy, revealed a positive predictive value of the telecolposcopic impression of between 81% and 82%, while the positive predictive value of an in-person impression was 80%.     

A pilot study on tertiary teledermatology: feasibility and acceptance of telecommunication among dermatologists

Tertiary teledermatology (TTD), where a general dermatologist consults a specialized dermatologist on difficult cases, is a relatively new telemedicine service. We evaluated TTD in a Dutch university hospital, where 13 general dermatologists used TTD to consult 11 specialized dermatologists and two residents at the university medical centre. We measured the avoided referrals to the university centre, the usability of the system and the user acceptance of it. During a three-month study, general dermatologists consulted via TTD 28 times. In 17 of the consultations (61%), the general dermatologists would have referred their patients to the university centre if teledermatology had not been available. Referral was not necessary after teledermatology for 12 of these 17 consultations (71%). The mean usability score (0-100) of all the users was 80. All dermatologists were satisfied with TTD (mean satisfaction of 7.6 on a 10-point scale) and acceptance was high. The baseline measurements showed that half of tertiary referrals were suitable for TTD. These results suggest that TTD reduces unnecessary physical referrals and that users are satisfied with it. A large-scale evaluation is now required.     

User satisfaction with a telemedicine amputee clinic in Saskatchewan

A group of 15 patients with amputee-related diagnoses were given a satisfaction survey after telemedicine assessment. Most of the videoconferencing sessions used an IP connection at 768 kbit/s. The patients were seen at four sites. The average connection time was less than 5 min and the average time for a session was approximately 40 min. Thirteen questions required scaled responses (poor, fair, good, excellent) and two required yes/no answers. The 13 categories broadly related to satisfaction with the telemedicine service and the quality of specialist care. In all categories, 97% of the responses fell in the good to excellent range. Concerns were raised about ease of access to local telemedicine sites, connection waiting times and lack of familiarity with telemedicine technology. The study showed that telemedicine was acceptable to patients with amputations and provided a reliable assessment of the amputee.     

A randomized controlled trial assessing the health economics of realtime teledermatology compared with conventional care: an urban versus rural perspective

A randomized controlled trial was carried out to measure the cost-effectiveness of realtime teledermatology compared with conventional outpatient dermatology care for patients from urban and rural areas. One urban and one rural health centre were linked to a regional hospital in Northern Ireland by ISDN at 128 kbit/s. Over two years, 274 patients required a hospital outpatient dermatology referral--126 patients (46%) were randomized to a telemedicine consultation and 148 (54%) to a conventional hospital outpatient consultation. Of those seen by telemedicine, 61% were registered with an urban practice, compared with 71% of those seen conventionally. The clinical outcomes of the two types of consultation were similar--almost half the patients were managed after a single consultation with the dermatologist. The observed marginal cost per patient of the initial realtime teledermatology consultation was 52.85 Pounds for those in urban areas and 59.93 Pounds per patient for those from rural areas. The observed marginal cost of the initial conventional consultation was 47.13 Pounds for urban patients and 48.77 Pounds for rural patients. The total observed costs of teledermatology were higher than the costs of conventional care in both urban and rural areas, mainly because of the fixed equipment costs. Sensitivity analysis using a real-world scenario showed that in urban areas the average costs of the telemedicine and conventional consultations were about equal, while in rural areas the average cost of the telemedicine consultation was less than that of the conventional consultation.     

General practitioners' perceptions of asynchronous telemedicine in a randomized controlled trial of teledermatology

We studied the perceptions of general practitioners (GPs) towards teledermatology, before and after its introduction into eight general practices for the purposes of a randomized controlled trial. A postal questionnaire was distributed before the trial and again one year later. Thirty-six of the 42 GPs responded on each occasion (a response rate of 86%). In the second survey, only 21% of respondents indicated that they were satisfied with teledermatology in their practice, while 47% said that they were dissatisfied. Thirty-one per cent said that they felt confident about diagnosis and management of care through teledermatology, and 28% reported that they were unconfident. Only 23% of respondents said that they would consider using a telemedicine system in the future, while 34% said they would not (43% were unsure). There were no significant findings to suggest that the GPs' perceptions changed over time. Less favourable responses to telemedicine were found than has been observed in previous studies, which suggests that the model of telemedicine described in this study would not be widely acceptable to GPs.     

Systematic review of evidence for the benefits of telemedicine

A systematic review of telemedicine assessments based on searches of electronic databases between 1966 and December 2000 identified 66 scientifically credible studies that included comparison with a non-telemedicine alternative and that reported administrative changes, patient outcomes, or results of economic assessment. Thirty-seven of the studies (56%) suggested that telemedicine had advantages over the alternative approach, 24 (36%) also drew attention to some negative aspects or were unclear whether telemedicine had advantages and five (8%) found that the alternative approach had advantages over telemedicine. The most convincing evidence on the efficacy and effectiveness of telemedicine was given by some of the studies on teleradiology (especially neurosurgical applications), telemental health, transmission of echocardiographic images, teledermatology, home telecare and on some medical consultations. However, even in these applications, most of the available literature referred only to pilot projects and to short-term outcomes. Few papers considered the long-term or routine use of telemedicine. For several applications, including teleradiology, savings and sometimes clinical benefit were obtained through avoidance of travel and associated delays. Studies of home care and monitoring applications showed convincing evidence of benefit, while those on teledermatology indicated that there were cost disadvantages to health-care providers, although not to patients. Forty-four of the studies (67%) appeared to have potential to influence future decisions on the telemedicine application under consideration. However, a number of these had methodological limitations. Although useful clinical and economic outcomes data have been obtained for some telemedicine applications, good-quality studies are still scarce and the generalizability of most assessment findings is rather limited.     

Changes in the job situation due to telemedicine.

Little is known either about how telemedicine changes the job situation or about how the working environment might be improved for those involved in telemedicine. To investigate these issues, qualitative interviews were carried out with 30 people in Norway working with telepsychiatry (12 respondents), teledermatology (six respondents), a telepathology frozen-section service (10 respondents) and tele-otolaryngology (two respondents). The median annual number of remote consultations in telepsychiatry was nine, in teledermatology 81 and in the telepathology frozen-section service nine. The positive aspects of working with telemedicine included less travelling, which gave more time for other work, less need to travel in poor weather, new contacts, an increased sense of professional security (because support was readily available) and the satisfaction of seeing partners in communication. At its present volume, telemedicine generally fits into daily work patterns quite well. Problems do occur, but they can be solved by appropriate organizational measures. Long-term scheduling of telemedical sessions may be important. Many telemedicine workers want to have the equipment in their own office. Working with telemedicine can be tiring and those interviewed wanted to limit the number of hours per week. A solution may be to use large clinics, such as university clinics, where the telemedical work could be distributed between several specialists. Large telemedicine clinics with a full-time dedicated staff would need careful consideration of working practices.     

Patient cost-benefits of realtime teledermatology--a comparison of data from Northern Ireland and New Zealand

As part of a randomized controlled trial of the costs and benefits of realtime teledermatology in comparison with conventional face-to-face appointments, patients were asked to complete a questionnaire at the end of their consultation. One hundred and nine patients took part in an initial teledermatology consultation and 94 in a face-to-face consultation. The proportion of patients followed up by the dermatologist was almost the same after teledermatology (24%) as after a hospital appointment (26%) and for similar reasons. Two hundred and three questionnaires were completed after the first visit and a further 20 after subsequent visits. Patients seen by teledermatology at their own health centre travelled an average of 12 km, whereas those who attended a conventional clinic travelled an average of 271 km. The telemedicine group spent an average of 51 min attending the appointment compared with 4.3 h for those seen at the hospital. The results of the present study, as in a similar study conducted in Northern Ireland, show that the economic benefits of teledermatology favour the patient rather than the health-care system.     

Patient satisfaction with telemedical access to specialty services in rural California

We assessed patient satisfaction with the use of telemedicine in rural California, in comparison with usual face-to-face care. A standardized patient satisfaction questionnaire was developed using a five-point scale to measure dimensions of care in a telemedicine environment. Twenty-four primary care sites in 18 Californian counties submitted satisfaction data. The patient response rate was 61% (n = 793). Consultations were provided in 27 specialties. The responses to the questionnaires indicated that telemedicine made it easier for patients to receive specialty care (91% of patients satisfied, mean score 4.6). There was general satisfaction with telemedicine (87%, mean 4.5), a willingness to continue receiving services (90%, mean 4.6) and most patients felt that they would not receive better care in person (61%, mean 2.3). Patients stated that they received the necessary information from specialists (85%, mean 4.5) and had their questions answered by a primary care provider or nurse (89%, mean 4.7). Seven hundred and forty-one patients submitted travel information. There was an average decrease in travel distance of 170 km and time savings of 130 min using telemedicine. The average cost of travel to a specialty appointment was $83 (n = 310). The present study suggests that telemedicine is acceptable to patients as a method of improving access to specialty expertise, and compares favourably with face-to-face care.     

Patient and physician satisfaction in a clinical study of telemedicine in a hypertensive patient population

We studied patient and physician satisfaction with telemedicine for the care of a hypertensive population. Once recruited, participants were seen both in person and via telemedicine (in random order) on the same day. After each meeting, patient and physician satisfaction surveys were completed. In the 12-month study, there were 107 pairs of visits. The physicians reported a small but significant increase in workload, mental effort, technical skills and visit duration for telemedicine when compared with face-to-face consultations. They noted that the telemedicine system worked well in the majority of cases and could reduce the need for future treatment. Patients reported slightly but significantly higher satisfaction scores for the following for in-person than for telemedicine meetings: technical quality, interpersonal care and time spent. Patients reported high satisfaction scores for both telemedicine and in-person visits.     

Telemedicine and changes in the distribution of tasks between levels of care

The present investigation, which was part of a larger study, was designed to answer the question 'Has telemedicine produced changes in the distribution of tasks between the general practitioner and specialist, or between the local hospital and university/central hospital?' Qualitative interviews were carried out with 30 persons involved in four telemedicine services in Norway: teledermatology, tele-otolaryngology, telepsychiatry, and a telepathology frozen-section service. The results indicated that telemedicine does not produce large changes in the distribution of tasks. The reported effects were largest and most complex for telepsychiatry, followed by teledermatology. Local variations in how telemedicine is practised may explain the variation in the findings between telemedicine applications.     

A comparative study of teleconsultations versus face-to-face consultations

We compared the diagnoses made by one dermatologist via telemedicine with those of another dermatologist made in a face-to-face consultation. The patients first underwent a teledermatology consultation and then a face-to-face consultation. A general practitioner was present with the patient in the videoconference studio. Videoconferencing equipment connected at 384 kbit/s was used. The doctor-patient relationship and the satisfaction of the patients and dermatologists in the two settings were assessed, as well as technical conditions during the videoconferences. There were 121 patients, with a mean age of 40 years (range 17-82 years). There was a high degree of concordance between the two sets of diagnoses, with 72% complete agreement and 14% partial agreement between the two dermatologists. A total of 116 patients (96% of those included) completed a questionnaire. Both the patients and the dermatologists were in general satisfied with the videoconferences. Videoconferencing with a participating general practitioner may be useful in dermatology, but the technique should be used only for selected patients.     

Mobile teledermatology: a feasibility study of 58 subjects using mobile phones

We investigated the diagnostic agreement between teledermatology based on images from a mobile phone camera and face-to-face (FTF) dermatology. Diagnostic agreement was assessed for two teledermatologists (TD) in comparison with FTF consultations in 58 subjects. In almost three-quarters of the cases (TD1: 71%; TD2: 76%), the telediagnosis was fully concordant with the FTF diagnosis. Furthermore, the diagnosed diseases were almost all in the same diagnostic category (TD1: 97%; TD2: 90%). If mobile teledermatology had been used for remote triage, TD1 could have treated 53% subjects remotely and 47% subjects would have had to consult a dermatologist FTF. TD2 could have treated 59% subjects remotely, whereas 41% subjects would have had to consult a dermatologist FTF. Forty-eight subjects responded to a questionnaire, of whom only 10 had any concerns regarding teledermatology. Thirty-one subjects stated that they would be willing to pay to use a similar service in future and suggested an amount ranging from euro5 to euro50 per consultation (mean euro22) (euro = pound0.7, US $1.4). These results are encouraging as patient acceptance and reimbursement represent potential obstacles to the implementation of telemedicine services.     

Patient satisfaction with teledermatology: quantitative and qualitative results from a randomized controlled trial

As part of a randomized controlled trial involving 208 dermatology patients, a quantitative and qualitative study was undertaken to explore patients' satisfaction with a specialist dermatological opinion and further management obtained through either a traditional outpatient consultation (control group) or an asynchronous teleconsultation (telemedicine group). There was a response rate of 71% to the quantitative patient satisfaction survey (148 replies from 208 distributed questionnaires). The responders comprised 80 of the 111 telemedicine patients (72%) and 68 of the 97 control patients (70%). Overall levels of patient satisfaction were high in both groups, and there was no significant difference between them. Ninety per cent of patients in the control group were satisfied with their overall care, compared with 81% in the telemedicine group, and 87% of patients in the control group were satisfied with their overall management, compared with 84% in the telemedicine group. Follow-up qualitative interviews with 30 of the participants also suggested that patients were generally positive about their care and management, regardless of group, age or gender. Receiving a diagnosis, treatment and cure, receiving adequate information and explanations, the need to be taken seriously, the need for individualized personal care, and the importance of a short waiting time for an appointment and treatment were all aspects of care and management most likely to result in patient satisfaction, regardless of modality.     

The other side of teledermatology: patient preferences

We studied patient preferences for a real-time teledermatology consultation or a conventional dermatology consultation. Dermatology patients were given the option of being seen by a dermatologist at their outlying primary care site via telemedicine or of being examined face-to-face by the same dermatologist at the primary care site. The same dermatologist provided the teleconsultations and the conventional consultations. During a 16-month study period, 52 patients were evaluated via telemedicine and 46 patients were seen face-to-face. The demographics for both study groups were similar. Those patients who selected telemedicine were more likely to have seen a dermatologist fewer than twice during the previous year, more likely to self-describe themselves in excellent health and more likely to choose a face-to-face evaluation when presenting with a possible skin cancer or a mole. Patients aged 56 years or less tended to be more likely to be seen via telemedicine, although the association with age was not significant (P = 0.06). This information may help providers to devise strategies to direct patients to telemedicine if and when it is appropriate.     

Patient satisfaction with store-and-forward teledermatology

We assessed patient satisfaction with a nurse-led store-and-forward teledermatology service in Manchester. A teledermatology nurse obtained the patient's history, took digital photographs of the patient's skin lesion and then sent the information to a hospital dermatologist, who responded with management advice the following week. Of 141 patients who attended their teledermatology appointment, 123 (50 male, 73 female) completed the study questionnaire (87%). The average age of respondents was 42 years (SD 17, range 18-90 years). Ninety-three per cent reported that they were happy with the teleconsultation while 86% reported that it was more convenient than going to the outpatient clinic. Forty per cent agreed that they would feel more comfortable seeing the dermatologist in person while only 58% were comfortable with not speaking to the dermatologist about their skin condition. The absence of interaction with the dermatologist and the delay in receiving management advice may have contributed to the somewhat low satisfaction rates.     

Patient and physician satisfaction with telemedicine for monitoring vital signs

We evaluated user satisfaction with realtime telemedicine for monitoring vital signs. Over eight weeks, 20 patients and 12 residents in family medicine participated in the study. At the end of the study, the patients and doctors completed a questionnaire detailing satisfaction with the service. Responses were obtained from 18 of the 20 patients and were generally positive: 61% were comfortable using the system and 94% did not believe that the technology had a negative effect on their relationship with the health-care provider. Eleven physician responses were obtained. Physicians were more uncertain about the benefits of the service: only 45% felt that telemedicine could adequately assess patients, although 82% felt that telemedicine would be an important part of primary-care services. From a user perspective, our study showed that patients were more satisfied with the telemedicine service than were doctors.     

Attitude to telemedicine, and willingness to use it, in audiology patients

We studied the willingness of patients to use telemedicine for ear- and hearing-related appointments, and the factors that influenced their decision to participate in telemedicine. A survey was designed with questions about patient appointments, perceived advantages and barriers to telemedicine, and prior use of the Internet for health-related matters. A total of 116 patients in four audiology centres were surveyed from December 2004 to May 2005. There were 54 male and 62 female respondents; 46% of the participants were aged over 66 years. In all, 75% had not previously heard of telemedicine. The most common reasons for willingness to use telemedicine were to reduce the time waiting for an appointment and cost. The most common barrier to using telemedicine was a preference for face-to-face visits. Of those surveyed, 32% were willing to use telemedicine, 10% would sometimes be willing, 28% were unsure, and 30% were not willing. There was no relationship between willingness and age or gender, except that women over the age of 55 years were less willing. Patients who had previously heard of telemedicine and used the Internet for health-related matters, especially men, were more inclined to have a telemedicine appointment.
