Physician acceptance of clinical information technology (IT) is important for its successful implementation. We propose that perceived threat to professional autonomy is a salient outcome belief affecting physician acceptance of an IT. In addition, level of knowledge codification of an IT is an important technological context affecting physician acceptance. Data from a sample of U.S. physicians were collected to test the hypotheses using partial least squares analysis. Results show that perceived threat to professional autonomy has a significant, negative direct influence on perceived usefulness of an IT and on intention to use that IT. Level of knowledge codification is also an important variable. The effect of perceived threat to professional autonomy is larger for clinical decision support systems than for electronic medical records systems. Awareness of these results would help managers better manage IT implementation in health care settings.
