OBJECTIVE: to measure the performance of teaching hospitals by Data Envelopment Analysis (DEA) and to study the influence of environmental factors on the efficiency. METHODOLOGY: A hundred and four teaching hospitals were analyzed and the efficiency score was generated by DEA, VRS model, output oriented, with weight restrictions. The efficiency score criteria were then regressed on non-discretionary variables by logistic linear regression. RESULTS: the efficiency score mean was 49% (SD=26%); five hospitals were efficient. In logistic regression, the main predictors of efficiency were the size of the hospital (p=0.001), high teaching intensity (p=0.027) and low teaching dedication (p=0.006). There was no association between efficiency and ownership form or HDI of the surrounding municipality. CONCLUSION: hospital efficiency suffers the influence of different environmental factors, not necessarily under the control of the manager, that should be considered when defining administrative goals and financing pacts.
