Abstract
Objective: This project's objective was to enhance efforts to improve vaccine-ordering efficiencies among targeted clinics using publicly purchased vaccines.
Design: Using an assessment of ordering behavior developed by the Centers for Disease Control and Prevention, we selected and trained immunization providers and assessed improvements in ordering behavior by comparing ordering patterns before and after the intervention.
Setting: A total of 144 Vaccines for Children program providers in Oregon.
Participants: We assessed 144 providers trained in the Economic Order Quantity process between January and November 2010.
Intervention (if applicable): Providers were invited to participate in regional trainings. Trainings included assignment of ordering frequency and dissemination of tools to support adherence to the recommended ordering frequency.
Main Outcome Measure(s): The percent increase in targeted clinics ordering according to recommended order frequency and the resulting decrease in orders placed, as an outcome of training and ordering tools.
Results: Only 35% of targeted providers were ordering according to the recommended ordering frequency before the project began. After completing training, utilizing ordering tools and ordering over a 7-month period, 78% of the targeted clinics were ordering according to the recommended frequency, a 120% increase in the number of clinics ordering with the recommended frequency. At baseline, targeted clinics placed 915 total vaccine orders over a 7-month period. After completing training and participating in the Economic Order Quantity process, only 645 orders were placed, a reduction of 30% .
Conclusions: The initiative was successful in reducing the number of orders placed by Vaccines for Children providers in Oregon. A previous effort to reduce ordering, without the use of training or tools, did not achieve the same levels of provider compliance, suggesting that the addition of staff and development of tools were helpful in supporting behavior change and improving providers' ability to adhere to assigned order frequencies. Reducing order frequency results in more efficient vaccine ordering patterns and benefits vaccine distributors, Oregon Immunization Program staff, and provider staff.
