OBJECTIVE:To reduce dispensing errors in Pharmacy intravenous admixture service(PIVAS),improve compound-ing quality of transfusion and guarantee the safety and rationality of clinic transfusion. METHODS:The case tracking method was applied to analyze each link of the work in PIVAS to find the reasons of configuration errors and control risk;and then the system tracking method was applied to analyze the hidden safety risk and the crack of quality from the inside of the system and work flow. Countermeasures and supporting continuous improvement were established to evaluate the effect of management before and after 6 months. RESULTS:Tracer methodology(TM)was adopted to find out the weakness in the key link and work flow of the cause of the configuration errors,the relative work pattern and work environment was improved,the relative system was formulated and completed,strength of rewards and punishment was increased. Through the implementation of the countermeasures,the number of dispensing errors was reduced from 81 to 38,and the error rate was reduced from 0.035% to 0.011%(P<0.01). CONCLU-SIONS:TM can be adopted in the key link and work flow of the cause of the configuration errors,aim at formulate and strictly carry out relative countermeasures to reduce errors in PIVAS,and promote the safety of drug use.

Objective To recognize normal sinus rhythm (NSR), ventricular tachycardia (VT) and ventricular fibrillation (VF) from each other accurately and promptly. Methods A nonlinear descriptor based on multi-scale analysis, Hurst index, as a feature to quantify the nonlinear dynamics behavior of the ECG signal, was quoted in this paper. Results The nonlinear technique, Hurst index was examined and evaluated with ECG signals extracted from MIT-BIH Arrhythmia Database, MIT-BIH Malignant Ventricular Ectopy Database, and CU Ventricular Tachyarrhythmia Database under a specific moving-window length. The experiment showed good performance of this nonlinear descriptor. When the window length was 5 s long, the recognition accuracy for each of NSR, VT and VF was 100%. Besides, the computing speed was much faster than the speed obtained with a traditional non-linear technique, the complexity measure algorithm. Conclusion The Hurst index has a strong potential for life-threatening ventricular arrhythmia recognition in clinical applications.
