Total laboratory automation in Japan. Past, present, and the future

The history of systematized automation in clinical laboratories in Japan started in 1981. At that time, about 12 laboratory technicians worked in a typical private University hospital laboratory (average size 1000 beds), whereas in national university hospitals (typical size 600 beds), the number of technicians was as low as 18-25. In 1981, the Kochi Medical School was founded as a new national school, and laboratory staffing was limited by the Ministry of Education to only 19 technicians for the first 3 years. Therefore, we started to develop a fully automated laboratory system by ourselves rather than accepting an intolerable shortage of technicians. The system was based on conveyor and robotic technology, and we called this approach systematization. Ten years later, systematized automation was introduced into the Japanese market. As a result, 72% of the national university hospitals in Japan installed commercial systems for systematization. There is a trend now in hospitals with sufficient numbers of technicians, to introduce fully automated systems in their laboratories as well, and even small hospitals with less than 100 beds are planning to introduce such systems. However, current technology is too expensive and not sufficiently standardized to meet the needs of these market segments in Japan. We recommend that companies agree on common shapes and sizes of racks and include more flexible robotic technology in their sample handling systems, to allow for plug and play systems and to make systematization affordable for every laboratory in the world.
