Bevezetés: A szerzők a laboratóriumi diagnosztikai tevékenység hatékonyságát jellemző paraméter, az ún. „turnaround time” meghatározására alkalmas számítógépes programot dolgoztak ki laboratóriumukban. A turnaround time a minta laboratóriumba való beérkezése és az orvosi validálást követő eredménykiadás között eltelt idő, mely jól jellemzi az eredménykiadás hatékonyságát, és ezért a laboratóriumok működésének fontos minőségügyi paramétere. Módszer: Analízisük során a sürgős, rutin- és speciális vizsgálatokat külön kezelve 6 hónap adatait dolgozták fel, és a turnaround time medián, 5- és 95-percentil értékeit adták meg. Meghatározták emellett a maximálisnak definiált turnaround time értéket (sürgős 1 óra, rutin 4 óra, speciális 2–14 nap) meghaladó turnaround time értékű vizsgálatok („kiesők”) arányát is az összes vizsgálati számra vonatkoztatva. Eredmények: A sürgős vizsgálatok esetében a medián turnaround time 9–70 perc, a rutinvizsgálatoknál pedig 33–190 perc között volt. A speciális vizsgálatok jóval heterogénebb képet mutattak, és általában megállapítható volt, hogy a kis mintaszámú, nem automatizált, immunkémiai és hemosztázis-tesztek esetében magas a turnaround time értéke és a kiesők aránya. A rutinvizsgálatok longitudinális analízise egyértelműen mutatta, hogy 2006 első félévében javultak a vizsgálatok turnaround time értékei a laboratórium valamennyi részlegén. A turnaround time hosszát befolyásoló egyik lényeges paraméter az orvosi validálás ideje, ami jelentősen csökkenthető egy autovalidáló program segítségével. A szerzők adatai alapján az autovalidálás bevezetése akár 1–2 órával is csökkentette a rutinvizsgálatok medián turnaround time értékeit. Az alkalmazott számítógépes program alkalmas akár a mintaszállítás effektivitásának jellemzésére is, amit a szerzők két különböző mintaszállítási infrastruktúrával rendelkező sürgősségi részlegük összevetésével mutattak be. Következtetések: Az itt ismertetett turnaround time analízis az általános rutin része a világ fejlettebb országaiban tevékenykedő diagnosztikai laboratóriumokban, ugyanakkor az első ilyen próbálkozást jelenti Magyarországon.
