Abstract:

Objective To investigate the efficiency of quality management for point-of-care testing（POCT） of blood gas analysis. Methods A quality management was set up to use professional tools to confirm the key elements for ensuring the quality of POCT in blood gas analysis. The quality management focused on constructing organizational structure and documenting all the process. Precision of internal quality control and bias of external quality control for pH value,partial pressure of carbon dioxide [p（CO_2）] and partial pressure of oxygen [p （O₂）_] in 2011 and 2015 were analyzed statistically. A score table was made and used to evaluate the efficiency of quality management for POCT in blood gas analysis. The effect of the results,such as inspection ability,clear structure,maneuverability,inspection quality,clinical satisfaction and after sale service,was evaluated. Results The results for precision of internal quality control and bias of external quality control had significant difference（P<0.05）. The average scores of the 6 dimensions were all improved,and the growth values were positive. The score of inspection ability was the highest with increasing by 5.1. Before and after the quality management,the difference had statistical significance（P<0.01）. Conclusions With the application of quality management,it is to clear the process,increase the inspection ability,ensure the inspection quality,increase the satisfaction degree for better clinical service.
