Comparative analysis of stat test turnaround times between emergency department and intensive care unit / 重庆医学

ABSTRACT

Objective To provide the objective evidence for reducing stat test turnaround time (TAT) reasonably through the comparative analysis of different intervals of stat test TAT between emergency department (ED) and intensive care unit (ICU ) . Methods Laboratory information system was used to collect data about blood cell analysis and biochemical profiles of department of emergency and ICU from 1st January to 31th March ,2014 ,then comparatively analyzing different intervals of stat test TAT be‐tween two departments .Results TAT outlier rates of stat CBC tests ordered by ED and ICU were 2 .4% and 15 .1% ,and that of stat biochemical profiles ordered by ED and ICU were 12 .3% and 24 .5% ,respectively .there were no significant differences in mean times between order‐to‐receipt of stat CBC tests and biochemical profiles ordered by ED and collection‐to‐receipt of stat CBC tests and biochemical profiles ordered by ICU [(11 .2 ± 4 .0) min vs .(11 .2 ± 4 .5) min ,P>0 .05 ;(13 .2 ± 14 .1)min vs .(13 .8 ± 9 .8) min ,P>0 .05] .ED had significantly shorter mean time of receipt‐to‐report than ICU for stat CBC tests and biochemical profile [(5 .8 ± 4 .4) min vs .(19 .3 ± 12 .5) min ,P0 .01] .The TAT mean times of stat CBC tests and biochemical profiles ordered by ED were shorter than those ordered by ICU [(17 .0 ± 6 .2) min vs .(30 .5 ± 14 .9) min ,P<0 .01 ;(46 .9 ± 17 .2) min vs .(49 .3 ± 16 .5) min ,P<0 .01] .Conclusion The ED TATs for CBC tests and biochemical pro‐files are reasonably set ,and each interval of the ED TATs is well controlled .The ICU TATs for CBCs and biochemical profiles should be reset ,and the process of stat test for ICU should be optimized .
