OBJECTIVES: We examined how family medicine clinic physicians and staff worked in collaborative teams to implement an automated clinical reminder to improve tetanus, diphtheria, and acellular pertussis (Tdap) booster vaccine administration and documentation.

METHODS: A clinical reminder was developed at 5 University of Michigan family medicine clinics to identify patients 11 to 64 years old who were in need of the Tdap booster vaccine. Quality improvement cycles were used to improve clinic care processes. Immunization rates from 2008 to 2011 were compared with rates at 4 primary care control clinics.

RESULTS: Vaccination rates among eligible patients increased from 15.5% to 47.3% within the family medicine clinics and from 14.1% to 30.2% within the control clinics. After adjustment for covariates, family medicine patients had a higher probability of vaccination than control patients during each measurement period (0.17 vs 0.15 at baseline, 0.53 vs 0.22 during year 1, and 0.50 vs 0.30 during year 2).

CONCLUSIONS: Automated clinical reminders, when designed and implemented via a consensus-based framework that addresses the process of care, can dramatically improve provision of preventive health care.
