Improving influenza vaccination performance in an HMO setting: the use of computer-generated reminders and peer comparison feedback.
We evaluated a program for improving influenza immunization performance in a health maintenance organization (HMO). The HMO implemented several interventions successively from 1984-87: a postcard reminder to members at high risk for complications of influenza, a computer-generated reminder to the physician at the time of any primary care visit by high-risk patients, performance feedback to chiefs of service, and, finally, retrospective feedback to each physician comparing his/her performance with that of the other physicians. We examined immunization rates for a group of members older than age 65, a high-risk group under age 65, and a group of diabetic members who had not been subject to the reminders (vs a group who had been covered by the program). Vaccination rates were increased in those diabetic members who received reminders. Nevertheless, among members younger and older than age 65 whose experience was observed over three flu seasons, a significant increase in vaccination rates was not achieved until physician feedback was added to the program. We conclude that each element of the reminder and feedback program has contributed to the overall increase in vaccination rates at the HMO and that effective ongoing influenza immunization programs can be implemented in practice settings with appropriate systems support.
