title: [Application of laboratory information system in the management of the key indicators of quality inspection].
abstract: OBJECTIVE
  To establish a system of monitoring the key indicator of quality for inspection (KIQI) on a laboratory information system (LIS), and to have a better management of KIQI.
  
  
  METHODS
  Clinical sample made in PUMCH were collected during the whole of 2014. Next, interactive input program were designed to accomplish data collecting of the disqualification rate of samples, the mistake rate of samples and the occasions of losing samples, etc. Then, a series moment of sample collection, laboratory sample arrived, sample test, sample check, response to critical value, namely, trajectory information left on LIS were recorded and the qualification rate of TAT, the notification rate of endangering result were calculated. Finally, the information about quality control were collected to build an internal quality control database and the KIQI, such as the out-of-control rate of quality control and the total error of test items were monitored.
  
  
  RESULTS
  The inspection of the sample management shows the disqualification rates in 2014 were all below the target, but the rates in January and February were a little high and the rates of four wards were above 2%. The mistake rates of samples was 0.47 cases/10 000 cases, attaining the target (< 2 cases/10 000 cases). Also, there was no occasion of losing samples in 2014, attaining the target too. The inspection of laboratory reports shows the qualification rates of TAT was within the acceptable range (> 95%), however the rates of blood routine in November (94.75%) was out of range. We have solved the problem by optimizing the processes. The notification rate of endangering result attained the target (≥ 98%), while the rate of timely notification is needed to improve. Quality inspection shows the CV of APTT in August (5.02%) was rising significantly, beyond the accepted CV (5.0%). We have solved the problem by changing the reagent. The CV of TT in 2014 were all below the allowable CV, thus the allowable CV of the next year lower to 10%.
  
  
  CONCLUSIONS
  It is an objective and effective method to manage KIQI with the powerful management mode of database and information process capability on LIS.
