The H1N1 flu outbreak in Tennessee: public health response and vaccine distribution challenges

H1N1 Briefing

Case Briefing:

This case details the outbreak of the H1N1 flu in Tennessee during 2009, from the initial appearance of the flu strain to the first Tennessee cases in the spring of the year through the virus' dissipation and subsidence in the winter of 2009-1010. Public health entities and their successes and failures in preparing for and then addressing the flu's progress in the face of certain practical difficulties are the focus of the description provided by the authors, with imbalances and inefficiencies in the distribution of vaccines and thus in the availability of the vaccine to the general population and sensitive target groups forming the fundamental problem in this case. Topics involved include healthcare, the complexities of intra-governmental and governmental-private interactions, and organizational communication.

Summary

The H1N1 flu virus was initially identified in Mexico, Texas, and California, in April of 2009, and other states began preparing for an epidemic due to the lack of vaccine for this new and apparently virulent strain. Knowledge about the flu was limited and recommendations from the CDC regarding preparedness and reactions were uncertain and frequently changing in the early days of the virus' spread, leading to some confusion with school closures in Tennessee after the first cases appeared there. The public health officials and network seemed well-prepared for the worst, however, and had time over the summer to hold meetings with other relevant entities and parties and to develop a registration system for healthcare practitioners -- physicians and pharmacists -- that would help to ensure vaccines were delivered in a fair and timely manner in accordance with established priorities once a vaccine had been developed. The flu began to spread in earnest during September, after schools were back in session, yet a vaccine did not become available until October and was at first only available in a form not fit for certain high-risk (and therefore high priority) groups. Misunderstandings and miscommunications regarding the vaccine's availability exacerbated the issue of availability, and though the flu strain proved to be less virulent and less easily spread than initially feared missteps were made in informing practitioners and the public of best practices in confronting the flu. By the time the vaccine was widely available there was lessened demand due to public fears and the subsidence of the epidemic worries.

Background

The H1N1 flu scare was part of a series of viral epidemic scares that created something of a subdued panic during the first decade of the new millennium. SARS, the Avian Flu, the Hanta virus, and others became fairly regular news items that excited public interest and quite rightly led to adjustments in medical preparedness and protocol. The CDC remained a consistent and centralized source both for providing data and recommendations to state health departments as well as tracking cases through reports from medical offices, however the coordination of prevention and treatment efforts at the operational level was very much a matter for individual states and, depending on each state's system, state regions/counties. Tennessee had a mixed system with some centralized and some more regionalized decision-making abilities, as the case describes, and the lack of centralization as well as a lack of truly accurate and consistent information from the CDC contributed to problems observed in this case, given the background of reliance on centralized information sources.

Conclusions

All of the problems in this case can be traced in some measure to communication issues. Communications with the public, between governmental agencies, and with physicians and pharmacies providing vaccines all took place with a fair amount of efficacy but with key gaps or missteps. Though practical issues of the virus itself and the lack of an appropriate vaccine created the problem, it could have been more effectively dealt with had there been a more established and tested means of communication amongst Tennessee's public health entities. Greater transparency and immediacy in communications would also have been desirable.

Recommendations

Tennessee and the relevant officials/authorities in the state clearly learned from the 2009 H1N1 outbreak, given their comments in the case, and the lessons of this case can also be used to generate broader recommendations regarding the handling of public health issues and communication issues in complex systems on a more general basis. It is highly recommended that current communication protocols and hierarchies be examined and tested as applicable to ensure that an event with rapidly changing information and a need for comprehensive knowledge can be properly addressed. Ensuring that a clear system of communication that includes all relevant parties is in place before an emergency event is the only real means of ensuring that it will adequately operate during an emergency event. It is also recommended that even loosely organized and laterally extended networks, such as Tennessee's public health network, be given some degree of centrality when it comes to communication in order to facilitate the more effective and efficient spread of knowledge.
