Amid provider reports of financial barriers as an impediment to adult immunization, this study explores the time and costs of vaccination in adult provider practices. Both a Vaccination Time-Motion Study and Vaccine Practice Management Survey were conducted (March - October 2017) in a convenience sample of 19 family medicine (FM), internal medicine (IM), and obstetrician-gynecology (OBGYN) practices, in nine states. Practices were directly observed during a one week period; estimates were collected of time spent on activities that could not be directly observed. Cost estimates were calculated by converting staff time for performed activities. In the time-motion study, FM and IM practices spent similar time conducting vaccination activities (median = 5 min per vaccination), while OBGYN practices spent more time (median = 29 min per vaccination). Combining results from the time-motion study and the practice management survey, the median costs of vaccination remained similar for FM practices and IM practices at $7 and $8 per vaccination, respectively, but was substantially higher for OBGYN practices at $43 per vaccination. Factors that contributed to higher costs among OBGYN practices were the increased time to counsel patients, administer vaccines, and to plan and manage vaccine supplies. In addition, 68% of OBGYN patients who were offered and counseled to receive vaccines declined to receive them. Counseling patients who ultimately do not go on to receive a vaccine may be an important cost factor. Lower costs of vaccination services may be achieved by increasing efficiencies in workflow or the volume of vaccinations.
