[Time requirements of medical and non-medical personnel for ultrasound studies].

To assess the time needed for ultrasound examinations for physicians and assistants we carried out a survey among members of the German Association of Ultrasound in Medicine (DEGUM) in hospitals and practices. The physician's examination time for the investigation of the upper abdomen and kidneys was 12.3 min with additional time for preparation (2.9 min), for work up (2.3 min) and written documentation (3.6 min), together 21.3 min. The examination times in practices (18.9 min) are shorter than in ultrasound labs in hospitals. Assistants in ultrasound laboratories need for organisation, upkeep of equipment, to filing the images in archives etc. medium 15.2 min per patient. Assistants with exclusive employment in the ultrasound laboratory need 17.6 min (4-57 min), whereas assistants employed in the ultrasound laboratory and other departments need 12.7 min (1.6-31 min). In internal practices the desired time is 7.9 min (3.5-20 min). Because of the different organisation in the ultrasound laboratories in several hospitals and in practices a comparison of times needed by assistant personnel (or, in many cases, by the physicians who perform such work themselves) is very difficult. The examination time really needed by physicians and the time for assistant personnel are shorter than presumed earlier, but are longer than estimated in the recent discussion about money saving in medicine.
