A paper written by John Fontanesi and myself was recently published in the October 2009 edition of the American Journal of Managed Care. The paper is titled “Delivering Vaccines: A Case Study of the Distribution System of Vaccines for Children.” The abstract of the paper is below:
Objective: To evaluate the efficacy of the central-
ization by the Centers for Disease Control and
Prevention of their pediatric vaccine distribution
system.
Study Design: In March 2007, the Centers for
Disease Control and Prevention began a pilot
program to reform the Vaccines for Children
(VFC) program. All California VFC providers
were required to place vaccine orders under
the centralized logistic system of the Vaccine
Management Business Improvement Project
(VMBIP). For this study, VFC ordering, use,
and delivery data were collected from 2 large
southern California healthcare providers that
collectively served more than 200,000 children.
Data collection occurred between January 2005
and June 2008.
Methods: This case study measures the change
in the mean VFC delivery times before and after
the VMBIP. The data underwent simulation to
estimate the number of days per year a provider
would have zero VFC inventory before and after
the VMBIP.
Results: After the VMBIP was implemented,
delivery times increased from 1.6 to 12.3 business
days (P <.001). The probability that VFC deliveries
took longer than 1 week increased from 7%
before the VMBIP to 89% afterward. Our simulation
demonstrates that for 7 of 11 vaccines investigat-
ed there was a statistically significant increase in
the number of days a provider would be without
VFC (P <.01).
Conclusion: Although the VMBIP was implement-
ed to save costs, this study finds that during the
VMBIP’s initial implementation timeline, providers
experienced longer delivery delays and a higher
probability of a VFC stockout.
