Abstract:Objective Under the operation of the clinical laboratory ISO15189 quality system, using the active intervention to study the percentage of inspection reports that have never been read and to find the after inspection(TAT) median change. Methods We collect data for hospitalized inpatients in our hospital in the first half of 2020 and the first half of 2021, the data contain inspection reports author time and first reading time. And the inspection item contains blood cell analysis, urine analysis, stool analysis, hepatic function test, renal function tests, blood electrolytes tests. In the unread reports, we classify and calculate the proportion of total according to the patient and item. If the reports has already been read, we classify and calculate after inspection (TAT) quartiles. 321279 samples were from 2020 and 436082 were from 2021. Results After active intervention, whether by the number of reports that patients have not read or by the type of item, their share has decreased. The after inspection (TAT) quartiles of the urgent reports is better the normal reports. The quartile after the intervention was better than before. Conlusion All indicators after the intervention were better than before the intervention, but we still need to continue to optimize. We need to reduce the number of unread reports as a percentage of the total and continue to work. When the report is reviewed, we also need to get the report read by healthcare workers faster.nread reports as a percentage of the total and continue to work.
