House staff attitudes about influenza vaccination after participation in a clinical trial to improve vaccination of hospital patients.

We surveyed house staff who had participated in a trial that compared influenza vaccination strategies for inpatients. House staff who were exposed to computer-generated vaccination orders were more likely to report that they recommended vaccination to their inpatients and outpatients, compared with house staff who were not exposed to a vaccination intervention. Also, house staff did not recognize pregnant women as a high-priority population for influenza vaccination.
