RESUMEN
Objective To investigate the clinical application value of the critical value electric reporting system .Methods The critical value data from Aug .1 ,2015 to Jan .31 ,2016 were inquired through the electronic hospital information system (eHIS) .The incidence rate of critical values ,items distribution and department distribution were analyzed .Results A total of 3 405 items of crit‐ical value were reported .The occurrence rate of critical values was 0 .45% .The top 5 of critical values numbers were chlorine (25 .76% ) ,myocardial‐specific isoenzyme of creatine kinase (19 .97% ) ,serum sodium (9 .43% ) ,platelet count (9 .05% ) and partial pressure of carbon dioxide (6 .40% ) .The top 5 departments of critical values reported number were the cardiology department (18 .94% ) ,followed by neurological intensive care unit (12 .04% ) ,intensive care unit (9 .52% ) ,second wards of neurosurgery (5 .11% ) and neurovascular wards (5 .02% ) .The median time of critical value report was reduced by 33 .33% and the quartile range time weas reduced by 40 .00% .Conclusion The application of critical value electric reporting system reduces the elapsed time of critical value report ,increases the promptness and accuracy of critical value report ,and has an important significance to guarantee the medical quality .
