Abstract:

Objective

To explore the effect of quality control circle in increasing the audit execution rate and improving quality of inspection report in clinical laboratory.

Methods

A quality control circle was set up to use professional tools to solve existing problems of inspection reports at 5 percent sampling of all the inspections. Before the application of a quality control circle method, the studied 2515 detection reports from Qctober 2012 to December 2012; after that, the studied 15089 detection reports from January 2013 to June 2014 in the clinical laboratory respectively. The exectution rate and cause analysis of the non-execution of double audit were compared. To confirm the effect of the intangible results such as application of quality control circle tool, communication coordination，brainstorm，teamwork spirit，question discovery and confidence, self efficacy scale was scored by 10 quality control circle members to compare the effect of activity score.

Results

The audit execution rate of inspection reports in clinical laboratory increased from 67.4% (1695/2515 reports) to 90.4% (13640/15089 reports) with significant difference (x²=983.16, P<0.01). To confirm the effect of intangible results, the average scores of application of quality control circle tool, communication coordination，brainstorm，teamwork spirit, question discovery and confidence obtained by questionnaire survey were totally increased more than 2.9, with the highest increment of 4.2 in application of quality control circle. Before and after the quality improvement, the difference is significant at the t value of -7.28, -6.53, -5.10, -9.66, -9.44, -5.34，P< 0.01 level.

Conclusion

With the application of quality control circle tools, the audit execution rate of inspection reports in clinical laboratory significantly increases and the quality management ability of quality control circle members to resolve actual clinical problems improves.
