Gender stereotypes and drinking cognitions as indicators of moderate and high risk drinking among young women and men

The study examined differences in gender stereotypes, restrained drinking and self-efficacy for alcohol refusal between moderate and high risk drinkers among a university sample of 301 women and 118 men. Both female and male high risk drinkers displayed a response conflict, typified by high scores on restrained drinking but low scores on self-efficacy. This pattern of response conflict was more pronounced for high risk drinking women, who also identified poorly with feminine trails (e.g. 'nurturing', 'love children', 'appreciative'). The findings are discussed in relation to society's double standard that accepts intoxication in men but condemns it in women. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.

A simulation model for analysing patient activity in dermatology

We developed a general model to assess patient activity within the primary and secondary health-care sectors following a dermatology outpatient consultation. Based on observed variables from the UK teledermatology trial, the model showed that up to 11 doctor-patient interactions occurred before a patient was ultimately discharged from care. In a cohort of 1000 patients, the average number of health-care visits was 2.4 (range 1-11). Simulation analysis suggested that the most important parameter affecting the total number of doctor-patient Interactions is patient discharge from care following the initial consultation. This implies that resources should be concentrated in this area. The introduction of teledermatology (either realtime or store and forward) changes the values of the model parameters. The model provides a quantitative tool for planning the future provision of dermatology health-care.

The potential of telemedicine for home nursing in Queensland

The potential for telemedicine in home nursing was examined by retrospectively reviewing the case-notes relating to home visits made by nurses in Queensland. The case-notes of 166 clients were randomly selected from 10 domiciliary nursing centres run by the Blue Care nursing organization in south-east Queensland. Two experienced community registered nurses independently undertook a retrospective review of the case-notes. Each reviewer made an independent judgement as to whether any of the home nursing visits in the episode of care could have been conducted by telemedicine. Visits requiring hands-on care were deemed to be unsuitable for telemedicine. A total of 12,630 home visits were reviewed. The median number of visits per client was 27 (range 1-722). The mean age of the clients was 72 years (range 2-93 years). A total of 1521 home visits (12%) were judged suitable for telemedicine. There was no significant difference in suitability between males (13%) and females (12%). Care interventions suitable for telemedicine were more likely to be those of a supportive, educational or review nature. Forty per cent of clients lived up to 5 km from the home nursing centre, 33% lived 5-10 km from the centre and 27% lived over 10 km from the centre. The results of the present study confirm the potential for telemedicine in home nursing in Australia.

A cost-minimization analysis of the societal costs of realtime teledermatology compared with conventional care: results from a randomized controlled trial in New Zealand

A randomized controlled trial was carried out to measure the societal costs of realtime teledermatology compared with those of conventional hospital care in New Zealand. Two rural health centres were linked to a specialist hospital via ISDN at 128 kbit/s. Over 10 months, 203 patients were referred for a specialist dermatological consultation and 26 were followed up, giving a total of 229 consultations. Fifty-four per cent were randomized to the teledermatology consultation and 46% to the conventional hospital consultation. A cost-minimization analysis was used to calculate the total costs of both types of dermatological consultation. The total cost of the 123 teledermatology consultations was NZ$34,346 and the total cost of the 106 conventional hospital consultations was NZ$30,081. The average societal cost of the teledermatology consultation was therefore NZ$279.23 compared with NZ$283.79 for the conventional hospital consultation. The marginal cost of seeing an additional patient was NZ$135 via teledermatology and NZ$284 via conventional hospital appointment. From a societal viewpoint, and assuming an equal outcome, teledermatology was a more cost-efficient use of resources than conventional hospital care.

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 f52.85 for those in urban areas and f59.93 per patient for those from rural areas. The observed marginal cost of the initial conventional consultation was f47.13 for urban patients and f48.77 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.

The effect of videoconferencing on the depth perception of observers

The ability of the human eye to perceive depth was measured using a specially designed instrument. Visual acuity and both monocular and binocular stereoacuity were measured when viewing the instrument directly and via a videoconferencing link. Ten subjects with an average age of 32.5 years (range 24-50) took part in the study. The group mean visual acuity using both eyes under normal test conditions was -0.04 logMAR (Snellen 6/5) compared with 0.18 logMAR (Snellen 6/10) for the video-link. The mean stereoacuity using both eyes was 37 (SD 18) under normal test conditions. When a videoconferencing link was used, the mean stereoacuity fell to 1218 (SD 1203) using one eye and to 1651 (SD 1419) using both eyes. The ability to perceive depth remotely via a video-link was significantly decreased compared with normal test conditions.

Telemedicine and developing countries - successful implementation will require a shared approach

Telemedicine is often proposed as a solution to certain health-care problems in the developing world. There seems to be little published experience on which to make judgements. A literature search revealed 39 articles, of which only two related to any kind of direct clinical work; most of them were review articles or editorials. The majority of the work reported was educational in nature, and there has been little clinical experience. It seems probable that telemedicine can help with the education of health-care workers and patients; it seems likely that it could bring major benefits to the organization of health-care. Without proper trials, it will be impossible to determine the place of health-care in the developing world. Trials are the only way in which rational decisions can ultimately be reached regarding whether scarce resources should be devoted to telemedicine in developing countries, or whether they should be employed in more conventional health-care measures whose outcomes are known to be cost-effective.

Experience with a low-cost telemedicine system in three developing countries

The Swinfen Charitable Trust was established in 1998 with the aim of helping the poor, sick and disabled in the developing world. It does this by setting up simple telemedicine links based on email to support doctors in isolated hospitals. The first telemedicine link was established to support the lone orthopaedic surgeon at the Centre for the Rehabilitation of the Paralysed (CRP) in Savar, near Dhaka in Bangladesh, in July 1999. An evaluation of the 27 referrals made during the first year of operation showed that the telemedical advice had been useful and cost-effective. Based on the success of the Bangladesh project, the Swinfen Charitable Trust supplied: digital cameras and tripods to more hospitals in other developing countries. These are Patan Hospital in Nepal (March 2000), Gizo Hospital in the Solomon Islands (March 2000), Helena Goldie Hospital: on New Georgia in the Solomon Islands (September 2000) and LAMB Hospital in Bangladesh (September 2000).

Cost implications of outpatient teleneurology

A randomized controlled trial was conducted to compare the costs of realtime teleneurology with the cost of conventional neurological care. Two district hospitals in Northern Ireland were equipped with videoconferencing units and were connected to the regional neurological centre by ISDN at 384 kbit/s. Of 168 patients randomized to the study, 141 kept their appointments (76 male, 65 female). Sixty-five patients were randomized to a conventional consultation while 76 were randomized to a teleconsultation. The average age was 44 years of those seen conventionally and 42 years of those seen by telemedicine. The groups had similar diagnoses. The telemedicine group required more investigations and reviews than the conventional group. The average cost of the conventional consultation was pound 49 compared with pound 72 for the teleconsultation. Realtime teleneurology was not as cost-effective as conventional care.

What constitutes success in telehealth?

Before telehealth applications can be judged, there must be some general understanding about what constitutes success. At first sight it seems that defining success in a telehealth application should be relatively easy: a successful application is one that produces high-quality care at low cost. However, the calculation of cost requires some care, since it depends on assuming a particular financial perspective (the patient's, the health-care provider's, or society's) and is meaningless without a statement of the workload being handled. Other factors include the context in which the service is being delivered. Ultimately, the political imperative may override any rational judgement of success.

The development of a pilot telemedicine network in Scotland: lessons learned

A pilot telemedicine network was established in 11 sites using funding provided by the Department of Trade and Industry in the UK. The main purpose of the project was to develop and evaluate clinical and educational links between central and peripheral sites in Scotland, The results were very encouraging, and clinical services were established in accident and emergency medicine, tele-ultrasound and clinical psychology. An undergraduate medical teaching service was also successfully established. All of these services are to be continued after the completion of the project. Many lessons were learned during the establishment of this network which will be useful in future projects. These included the importance of training for telemedicine users, the importance of identifying a telemedicine champion, the pitfall of health economics and the fact that services must be needs driven.

The point-of-referral barrier - a factor in the success of telehealth

A feasibility study was carried out to test the hypothesis that, for an effective telehealth service, a full-time coordinator is required to act as a single point of contact for consultation requests. By shifting the responsibility for telepaediatrics from the referrer to the provider, the telehealth process becomes equally (or more) attractive as the conventional alternative. Preliminary results showed that, within six months, telepaediatric activity increased to an average of 8 h per month. Not only did certain health services become more accessible to children and their families in remote areas of Queensland, but significant savings were also made. At least 12 patient transfers were avoided to and from the tertiary facility, with an estimated minimum saving of $18,000 to the health-care provider.

An analysis of why telehealth systems in Australia have not always succeeded

Telehealth programmes are rather similar to humans in the way that they are planned, develop, grow and ultimately die or disappear. To achieve good life expectancy for a telehealth programme there appear to be three major needs: nurturing, which includes the provision of money, ideas, education, training and innovation; experience, which involves an integrated management process, the achievement of long and wide patterns of usage, the development of updated policies and procedures and the involvement of multiple disciplines; success, which involves evidence of outcomes, evaluation and research, and, most important, the sharing of information through scientific and popular press publications, and conferences and collaborations with internal and external groups. The future of telehealth in Australia is at a watershed. There are now a substantial number of programmes, and there has been a large amount of financial and human investment in telehealth around the nation. There is, however, no forum for national leadership, no national association and little support at federal government level.
