Is it always either too late or too early to assess a new technology?: The example of a new X-ray detector for conventional radiography.

EVAL, Paris, France.

In an ideal world, there would be an ideal strategy to assess new diagnostic technologies, with ordinaly classified levels of assessment: 1. technical assessment, 2. diagnostic performance, 3. diagnostic improvement, 4. impact on medical decisions, 5. impact on patients health. But all potential financers of assessment are not interested in all levels, and they may first want results from higher levels to get involved. A team of Russian Nuclear Physicists have used their knowledge in particles detection (multiwire proportional chamber) to develop a digital imaging device, which is routinely used by some physicians in Moscou and Novosibirsk. The only scientific assessment showed a dramatic reduction of X-ray doses (5 to 300 times less than conventional radiography). But it remains a technologically and commercialy imperfect prototype with no scientific clinical assessment. We decided to get one device in Paris (Hopital Saint-Vincent de Paul), in order to assess: 1. technical limits and needed improvements, 2. effective reduction of doses, 3. diagnostic information in some definite indication. A one year and half "battle" took place: 1. Health authorities (Health ministry Hospital administration from AP-HP and its assessment center -CEDIT-, experts in radiology) wanted to be convinced that it was not too early: "first improve the device", 2. Industrial authorities (Industry ministry and related granting institutions) wanted to be convinced that the device was a potentially future industrial product: "it may be too late regarding R&D of medical imaging industrials in this field, or too early because none of them is involved in your project, or you should become an industrial yourself". Happily, as a Nobel Prize in Physics participate to the project, we got a sponsoring grant by a health industrial not involved in medical imaging technologies (Baxter Company). This allowed us to start all the process, and the other partners followed: both technical and clinical assessments could begin in September 1994 preliminary results with be presented.
