laboratory performance - evaluation of immunohaematology external quality assessment results during 19 years in Austria}, series = {Clinical Chemistry and Laboratory Medicine (CCLM)}, volume = {2018}, journal = {Clinical Chemistry and Laboratory Medicine (CCLM)}, number = {56 (12)}, pages = {2039 -- 2046}, abstract = {Background ISO 9001 and ISO 15189 have been established as continuative models for quality systems beyond national laws, mandatory standards and guidelines of expert associations regarding analytical and organisational performance of medical laboratories and transfusion services. Although widely used, their impact on laboratory performance has not been investigated. Methods We retrospectively analysed the results of 167 laboratories in 59 distributions of the Austrian red cell immunohaematology external quality assessment (EQA) scheme in the years 1999-2017. The performance for each parameter and trends of individual participants were compared with respect to certification or accreditation status of participants' quality systems and to laboratory type. Results Considering more than 52,000 EQA results, the absence or presence of a laboratory quality management system showed different error rates. Laboratories with ISO 9001 or ISO 15189 certification/accreditation had 0.7\% incorrect results, while this rate was doubled without such quality systems (1.4\%, p=0.0002). Statistically significant error reductions were seen upon ISO 9001/ISO 15189 implementation (1.3\% before vs. 0.7\% after; p=0.0468). Transfusion services had fewer errors (0.9\%) compared to hospital and independent laboratories (both 1.2\%). Conclusions Implementation and maintenance of quality systems according to ISO 9001 or ISO 15189 as well as laboratory specialisation result in better analytical performance as can be seen in immunohaematology EQA results. The conclusion is that these results apply to other laboratory tests and perhaps to other areas of health care.}, subject = {ISO 15189}, language = {en} } @inproceedings{MayrHoferRafoltetal., author =
