For an easy use of model reduction techniques in applications, software solutions are needed. In this paper, we describe the MORLAB, Model Order Reduction LABoratory, toolbox as efficient implementation for dense, medium-scale linear time-invariant systems. Giving introduction to underlying programming principles toolbox, show basic idea spectral splitting and present overview about implemented...

There continues to be an unrelenting rise in the volumes of laboratory tests ordered in medicine, which is both expensive and has the potential for over-investigation. We performed a quantitative, observational, cross-sectional study of staff with the authority to initiate a laboratory test, using a voluntary, anonymous questionnaire. Our aim was to assess the awareness of and attitudes towards...

OBJECTIVES There is a need to develop and validate new metrics to access the appropriateness of laboratory test requests. METHODS The mean abnormal result rate (MARR) is a proposed measure of ordering selectivity, the premise being that higher mean abnormal rates represent more selective test ordering. As a validation of this metric, we compared the abnormal rate of lab tests with the number ...

OBJECTIVE To analyze the requesting patterns for a range of laboratory tests ordered in 2009 from eight laboratories providing services to eight health areas, using appropriate indicators. DESIGN Indicators measured every test request per 1,000 inhabitants, and indicators that measured the number of tests per related test requested by general practitioners were calculated. The savings generat...

OBJECTIVE Laboratory tests are ordered on a daily basis, even though disease probability is often very low. Abnormal results, especially mildly abnormal results, can be difficult to interpret in these circumstances. Further insights into the occurrence of abnormalities can help improve rational test ordering and test interpretation. The objective was therefore to examine the frequency of mildly...
