Abstract
Finding new solutions for the challenge of cost- effective patient care without hazarding
the high quality of medical standard, is the key to optimization of the German
health system.
Means like staff reduction, implementing purchasing pools or digitalization of radiology
have been generally established in Medical Care Management. The next step to
economization is optimization of the involved processes.
One of the important benchmarks to compare the performance of radiologic departments
is the “report turn-around time” (RTAT), the period of time between the x-r ay
examination and the validation by the specialist, as together with the availability of
prompt radiologic diagnostics it has direct influence on the average length of stay and
thereby on the economic success of every single hospital.
For the optimization of the RTAT we used the Six-Sigma-Method, well-known from
process management in manufacturing industries, e.g. General Electric or Toyota. The
core elements of Six- Sigma are to describe, measure, analyze, improve and control all
kinds of processes using statistical methods. Furthermore it offers by its firmly structured
approach to process analysis an excellent base for process-oriented management.
By using Six-Sigma we were able to shorten the RTAT depending on the modality (CR,
CT or MRT) and on the interesting specified time interval (4h, 8h, 12h) between 3%
and 20%.
The amount of long lead time reports (LLTR) (more than 24h RTAT) could be reduced
from 9,2% to 3,9% of total reports.
Now we are able to validate independently of weekdays or time of day 96,1% of total
reports. The aim of eliminating every single LLTR was not achievable. 37% of the remaining
process-conform LLTR were due to extended acquisition time, 57% to delayed
validation. The amount of non-process-conform LLTR were reduced from 40% of total
reports to 6%.
As positive side-effect the implementation of Six-Sigma led to a general improvement
of understanding of intern process management in our members of staff.
Using the same human and technical resources process transparency combined with
optimization and consequent error prevention makes significant higher performance
possible.
