RESUMEN
Objective To know the relative efficiency condition in some cardiovascular surgical ICU for the nursing administrator to allocate the nursing resources.Methods Used the C2R model and the G2GS2 model to evaluate the effeciency of nursing manpowers in 12 cardiovascular surgical ICUs.Results The percentage of decision-making unit was 75% from the aspect of pure technique.The inefficent units can achieve the same levels of effeciency as the efficiency units by altering their inputs.Conclusions The coexistence of insufficiency and lower effeiciency were found in the nursing resource utilization of some cardiovascular surgical ICU,with a DEA based approach,we are able to provide scientific basis for the resource allocation through identifying the level of nursing efficiency.
