PURPOSE To present the lessons learned from an evaluation of a comprehensive telehealth project regarding success factors and evaluation methodology for such projects. METHODS A recent experience with the evaluation of new telehealth services in BC, Canada, is summarized. Two domains of clinical applications, as well as educational and administrative uses, and the project environment were evaluated. In order to contribute to the success of the project, the evaluation included formative and summative approaches employing qualitative and quantitative methods with data collection from telehealth events, participants and existing databases. The evaluation had to be carried out under severe budgetary and time constraints. We therefore deliberately chose a broad ranging exploratory approach within a framework provided, and generated questions to be answered on the basis of initial observations and participant driven interviews with progressively more focused and detailed data gathering, including perusal of a variety of existing data sources. A unique feature was an economic evaluation using static simulation models. RESULTS The evaluation yielded rich and detailed data, which were able to explain a number of unanticipated findings. One clinical application domain was cancelled after 6 months, the other continues. The factors contributing to success include: Focus on chronic conditions which require visual information for proper management. Involvement of established teams in regular scheduled visits or in sessions scheduled well in advance. Problems arose with: Ad hoc applications, in particular under emergency conditions. Applications that disregard established referral patterns. Applications that support only part of a units services. The latter leads to the service mismatch dilemma (SMMD) with the end result that even those e-health services provided are not used. The problems encountered were compounded by issues arising from the manner in which the telehealth services had been introduced, in particular the lack of time for preparation and establishment of routine use. Educational applications had significant clinical benefits. Administrative applications generated savings which exceeded the substantial capital investment and made educational and clinical applications available at variable cost. CONCLUSION Evaluation under severe constraints can yield rich information. The identified success factors, including provision of an overarching architecture and infrastructure, strong program management, thorough needs analysis and detailing applications to match the identified needs should improve the sustainability of e-health projects. Insights gained: Existing assumptions before the study was conducted: Evaluation has to proceed from identified questions according to a rigorous experimental design. Emergency and trauma services in remote regions can and should be supported via telehealth based on video-conferencing. Educational applications of telehealth directed at providers are beneficial for recruitment and retention of providers in remote areas. Insights gained by the study: An exploratory approach to evaluation using a multiplicity of methods can yield rich and detailed information even under severe constraints. Ad hoc and emergency clinical applications of telehealth can present problems unless they are based on thorough, detailed analyses of environment and need, conform to established practice patterns and rely on established trusting collaborative relationships. Less difficult applications should be introduced before attempting to support use under emergency conditions. Educational applications are of interest beyond the provider community to patients, family and community members, and have clinical value. In large, sparsely populated areas with difficult travel conditions administrative applications by themselves generate savings that compensate for the substantial capital investment for telehealth required for clinical applications.

PURPOSE To compute cost-effectiveness/cost-utility (CE/CU) ratios, from the treatment clinic and societal perspectives, for high-dose palliative radiotherapy treatment (RT) for advanced non-small-cell lung cancer (NSCLC) against best supportive care (BSC) as comparator, and thereby demonstrate a method for computing CE/CU ratios when randomized clinical trial (RCT) data cannot be generated. METHODS AND MATERIALS Unit cost estimates based on an earlier reported 1989-90 analysis of treatment costs at the Vancouver Island Cancer Centre, Victoria, British Columbia, Canada, are updated to 1997-1998 and then used to compute the incremental cost of an average dose of high-dose palliative RT. The incremental number of life days and quality-adjusted life days (QALDs) attributable to treatment are from earlier reported regression analyses of the survival and quality-of-life data from patients who enrolled prospectively in a lung cancer management cost-effectiveness study at the clinic over a 2-year period from 1990 to 1992. RESULTS The baseline CE and CU ratios are

CONCLUSION The cost effectiveness and cost utility of high-dose palliative RT for advanced NSCLC compares favorably with the cost effectiveness of other forms of treatment for NSCLC, of treatments of other forms of cancer, and of many other commonly used medical interventions; and lies within the US
