[Comparative research on evaluation methods of quality of injury surveillance-based emergency room].
OBJECTIVE
To evaluate the quality of injury surveillance based-emergency room and find a simple, convenient and practical comprehensive evaluation method.


METHODS
Seventeen indexes were extracted from influencing factors questionnaires of injury surveillance which was collected in the emergency room of a general hospital from July 2006 to March 2007, evaluated by TOPSIS (Technique for order preference by similarity to ideal solution) and GRA (grey relational analysis), given the order and compared with the practical results from injury surveillance reporting cards and emergency department logs.


RESULTS
The correlation coefficient between GRA and practical results was 0.750 (P = 0.020). The correlation coefficient between TOPSIS and practical results was 0.167 (P = 0.668). The correlation coefficient between GRA and TOPSIS was 0.083 (P = 0.831).


CONCLUSIONS
GRA is more suitable than TOPSIS for evaluation of the quality of injury surveillance based-emergency room, and it can be used to evaluate the quality of injury surveillance, and provide timely and effective basis for injury prevention strategies.
