Benchmarking diagnostic laboratory performance: Survey results for Germany, Austria, and Switzerland.

Altogether, 65 laboratories participated in the survey, 42 were hospital laboratories and 23 were commercial laboratories. Potential for further improvement and standardization became apparent across the board, e.g. use of IT for order management, auto-validation, or turn-around time (TAT) monitoring. Notably, a gap was identified regarding services provided to physicians, in particular "reflexive test suggestions", "proactive consultation on complex cases", and "diagnostic pathways guidance", which were only provided by about two thirds of laboratories. Concordantly, within-laboratory TAT (Lab TAT) was monitored by about 80% of respondents, while sample-to-result TAT, which is arguably the TAT most relevant to clinicians, was only monitored by 32% of respondents. Altogether, the need for stronger integration of the laboratory into the clinical care process became apparent and should be a main trajectory of future laboratory management.
